Description 1.1. GENERAL SYSTEM DESCRIPTION SYSTEM DESCRIPTION Ring-Master CB901 is an all-to-all direct speech system, controlled by a fully electronic central exchange. The brain of the system is a 16-bits microprocessor offering the user a wide selection of programmable features, designed to achieve flexibility and optimal efficiency in internal communication. The systemconfiguration (numbering plan, etc.) as well as all features are simply programmed by using a dataterminal or PC (Personal Computer) The processorcard in the CB901 has built-in non-volatile memory. This secure that the memory of the system, where all programmed information, features and system configuration are stored, will be maintained for up to 10 years. FAIL-SAFE POWER SUPPLY SUBSCRIBER CAPACITY, FROM 2 to 7170. The modular structure of the central permits easy expansion. Each subscriber card ( 8 subscriber positions) simply plugs in into the basic cardrack. A wide range of stations are available, such as desk stations, surface and flush mounted stations, light and heavy industrial stations, explosionproof stations, etc. SIMPLIFIED CABLING The unique cabling concept allows for different cabling arrangements. Both the power supply and controlunits can be mounted decentralized. Each station requires one single pair for audio and signalling and one pair for power supply. It is not necessary to power the stations from the central, remote groups of stations can be supplied from local mains power units, to save cabling. In addition, the controlunit itself can be decentralized. Each controlunit (stage) for 240 subscribers can be installed anywhere in the system. The interconnection cabling between the master unit and the stages is ordinary telephone wire or optical fibre. COMPACT SIZE The basic cardrack DP979, equipped for 96 subscribers measures only 256mm x 570mm x 271mm (10.1" x 22.4" x 10.9"). Silent in operation, once fitted with its cover, the central can operate inconspicuously in almost any location. The Ring-Master CB901 system is divided into 4 categories based on the number capacity: Single-Stage System CB901-1; up to maximum DP979/DP991 240 subscribers 80 subscribers Double-Stage System Ring-Master CB901-2; above 240 and up to 480 subscribers Triple-Stage System CB9013; above 480 and up to 717 DP980/DP992 subscribers 160 subscribers Multi-Stage System CB901Ring-Master M; above 717 up to max. 7170 subscribers SINGLE-STAGE SYSTEM, CB901-1. Up to 240 subscribers. In a Single-Stage System, CB901-1, the central unit consists of a Basic 5 SYSTEM CONFIGURATION System CB901 Description Ring-Master Cardrack DP979/DP991(CE certified) containing the Basic Cardset DP952E and Subscriber cards DP978/DP990 (for display stations). There is room for max. 10 DP978’s, i.e. 80 subscribers. If the number requirements exceed this, an additional Subscriber Cardrack DP980/DP992 (CE certified) can be added, giving a maximum capacity of 240 subscribers in a single-stage system. In a Double-Stage System, CB901-2, two Single-Stage Systems CB901-1 are interconnected by an 18-pair installation cable. This gives the system 8 interlinks between the stages. The maximum distance between the stages is 1.5 km. Each stage can have 240 subscribers, giving a maximum capacity of 480 in a Double-Stage System. The Triple-Stage System CB901-3 configuration consists of three Single-Stage Systems CB901-1 interconnected by 18-pair installation cable in a triangle configuration. The system is equipped for 8 interlinks between each stage. Maximum distance between the stages is 1.5 km. Each stage can have 239 subscribers, giving a maximum capacity of 717 in a Triple-Stage System. The Multi-Stage System CB901-M configuration consists of one control unit called DNC (Digital Network Controller) and up to 30 slave stages. The DNC unit has no subscriber connections itself, all slaves are wired to this unit and it handles all traffic between them. For interconnection, fibre optic or standard 2-pair telephone cable can be used. Each slave stage contains maximum 239 call numbers, which gives a total capacity of 7170 subscribers in a system. A Multi-Stage System CB901-M has 8 interlinks (audio channels) between the DNC unit and each slave stage and the DNC unit itself has 1024 internal audio channels. LINK CAPACITY Each slave-stage of 240 (239) call numbers is equipped with 15 internal links. Each Digital Network Controller (DNC) is equipped with 1024 internal links. Between each slave-stage and the DNC unit 8 interlinks are available. Stations for the CB901 systems can be classified in 2 main groups: MASTER STATIONS - (Ring-Master category AA) Stations that can initiate and receive calls. SUBSTATIONS - (Ring-Master category AB) Stations that can only receive calls or have a limited initiation capacity. A wide range of stations can be supplied for the CB901 systems. This includes the Master Station AA960, a loudspeaking desk station with a 8-character alphanumeric display containing a variety of user information. AA960 is designed for desk use or wall mounting, using the neat wallbracket GF933. Station AA916 is a Master Station without display, but with the same range of system features as AA960. Furthermore the AA903 for flushmounting, two types of industrial master stations, explosionproof stations and a variety of substations for desk and/or wall mounting are available. Microphone units for use together with external loudspeakers can also be supplied. All Master Stations have a full international keypad layout. This keypad is used both for initiating calls and for dialling feature codes. To dial another subscriber, the initiator presses the first digit of the desired call number. Immediately a call tone is heard, indicating that a free link is obtained and that the remaining digits can be dialled. As soon as a connection is established, both parties hear a warning tone of approx. 1 second, and in both stations the red lamp is lit. The conversation can continue until one of the parties presses the X-button to cancel the call. If the called station is in privacy mode, the caller will hear a warbling tone.

The Subscriber Cardrack DP980/DP992 has room for addional subscriber cards: 18-37 NFE1625 (DP978)/NFE1813 (DP990-for display stations) - Subscriber Cards, 8 subscribers on each card. Each stage in a CB901 system consists at least of one DP979/DP991 Basic Cardrack. If there are more than 96 subscribers in the stage, the Subscriber Cardrack DP980/DP992 must be added. All PCB’s in the CB901 system are plug-in to simplify expansion. Each subscriber card DP978/DP990 is prepared for 8 subscribers. The Basic Cardrack DP979/DP991 has room for 10 Subscriber Cards DP978/DP990 = 80 subscribers. The Subscriber Cardrack DP980/DP992 has room for further 20 Subscriber Cards DP978/ DP990 = 160 subscribers. This adds up to 240 subscribers per stage and each stage has 15 internal conversation channels (links). NOTE: If no Subscriber Cardrack is installed in a system, the Basic Cardrack can be equipped with 12 subscriber cards (96 subscribers). In the CB901-3 and CB901-M systems, each slave has 239 subscribers. Whenever auxiliary equipment is connected that requires subscriber positions, the number of subscriber positions will be reduced equally. Note. The CE certified central units are: DP991, DP992 and the ventilation unit DP992. 7 System CB901 Description THE BASIC CARDSET DP952E Ring-Master This microprocessor controlled Basic Cardset consists of 7 cards, and in the following we will give you a short explanation of each one: Processor Card NFE1683 This card contains the microprocessor (MC 68000 series), its program and memory. The 512K bytes program, which controls all computer operations is located in 4 plug-in PROMs (Programmable Read Only Memories). This enables easy updating of the system’s specifications. The operating system is MTOS and the program is written in high level language C. Timing Control Card NFE1606 This card contains the main oscillator (10.7 MHz) and provides all timing signals in the central unit. In this way the system is synchronized all the way through, which minimizes noise generation in the audio links Switch Control Card NFE1519 This card sets up / disconnects links, directed by the processor. It handles the PAM(Pulse Amplitude Modulation) sampling control for all links. There are 32 time-slots in the system. One time-slot is allocated for the subscriber scanner and one for the tone receiver, leaving 30 time-slots for audio connections. This means that there is room for 15 simultaneous audio links. Audio Control Card NFE1607 The voice control circuits (duplex and simplex) are located on this card, together with the tone receiver for dialling and tone transmitter for optional features. Link Card NFE1521 (x2) It connects the audio signals between the subscribers. Each subscriber is connected to one time-slot, and each of the two link cards can control 15 time-slots. Power Card NFE1528 It contains a switching power supply, synchronized with the main oscillator to minimize noise. The circuits on the card transfer the incoming 24 V DC into the internal control voltages: +12V, -12V, +5V and -5V. Subscriber Card NFE1625 (DP978)/NFE1813 (DP990) It terminates the lines (1-pair cable per station) for 8 subscribers and is the interface card between the stations and the central unit. The card splits up the audio/signalling information to/from the subscribers. Two models of the subscriber card are available. NFE1625 (DP978) operates with all types of stations, except AA960 with display, (will work, but no indication in display). The model NFE1813 (DP990) must be used for full feature operation with the display station AA960. All other stations will also work with this subscriber card. Both cards can be installed in the same system One other PCB can be inserted in the Basic Cardrack DP979/DP991): Program Distribution Control Card NFE1626 (DP977) It interfaces the internal communication system to external program sources and allows the subscribers to activate and connect program (music) channels as well as alarm channels. The card contains circuits that enable each subscriber to individually choose from any of the program channels and to choose the desired volume. It also contains 2 alarm channels, one with priority over the other. The alarm channels are activated by external contacts and spoken messages can be transmitted to all stations e.g. from a tape recorder. 8 System CB901 Ring-Master THE NUMBERING PLAN Description The numberíng plan of the central is flexible. Any station can have any call number within the choosen number series. A call number can have 2, 3, 4, 5 or 6 digits. As standard, the number series start with 10, 100, 1000, etc. Using the Service Terminal, you can determine any of the digits from 1 - 9 to be the first digit in a call number. Digits that are not used as first digit in a call number can be used for feature codes. A feature code can have 1, 2, 3, 4, 5 or 6 digits. The number of digits in a call number is determined by switches on the Timing Control Card NFE1606. Complete system configuration and feature programming is carried out using a special software program SVT (SerVice Terminal). The service terminal is interfaced via the RS 232 port to the CPU card NFE1683. Remote service/programming is also possible via modems. Using a PC (Personal Computer), the system configuration/features can be stored on a floppy disk. The Ring-Master CB901 uses electronic crossconnections, i.e. all numbering or renumbering of extensions is made by onsite programming, without the need for time-consuming rewiring on a crossconnection frame. Programming/reprogramming of call numbers is also possible from any master station or from a single dedicated master station. This eliminates the need of the Service Terminal, but is intended for service personnel only. STENTO ASA can supply a model of the System CB901 system to meet the CENELEC (Comité Européen de Normalisation Électrotechnique) requirements for EMC (Electro Magnetic Compatibility). The equipment have been successfully tested by the accredited Danish institute DELTA and complies with the standards: EN-50081-1 for emission and EN-50082 for immunity as prescribed in the "EMC Directive".

Stations The stations are basically divided into two categories; Master Stations and Sub Stations. Master Stations - able to make calls and to receive calls from any other call number. Sub Stations - for receiving calls only, from any master station. Some substations have keypad with limited call access (station with auto-dialling and stations with direct access feature). A variety of models are available. These include the display master station AA960 and master station AA916 without display, (they are both one-piece units designed for desk or wall-mounting). Several industrial master stations are available: AA903/ AA905/ AA906/ AA911/AA912 and AA961, substations AB911/ AB912/ AB92/ ex-proof station AF903, vandal proof stations AB931/AB933, door stations AB931A/AB933A and remote microphone and loudspeaker units. Each master station is equipped with a keyboard with full international standards, simple push-button dialling process places all the features at the user’s finger tips. Making a call, the user presses the button corresponding to the first digit of the desired call number. Dial access is virtually instantaneous since all station positions are scanned continuously. On receiving a steady dialling tone, the user continues dialling. Call connection is indicated in both the initiating and the receiving station by a warning tone and a station lamp which remains lit until the call is cancelled by either party pressing X. Should the receiving station be busy, the caller receives an intermittent tone. A continuous warbling tone indicates, that a station is placed in privacy, wishing to remain undisturbed. All Ring-Master stations are CE certified and complies with EMC Directive 89/336EEC. Excellent sound reproduction. Multi-colour LED for indications.

System CB901 Ring-Master Features CHAPTER 3. Features. Note. The description of the features in this handbook is based on the software version TX5.0. The performance of a feature in the display station AA960/aa961, can differ from the rest of the Ring-Master stations which have no display or keys F, *,# and M. Specific display station operation is indicated with italic font. Microphone Cutoff Allows a user to say something confidential to a person in the same room without this remark being heard by the other party. To temporarily disconnect the station microphone, press down the M key (mute). The letter M will be displayed. Release the key to continue in loudspeaking mode. If the M-button is pressed twice (within 0,4 sec.) the microphone mute function is locked into mute mode. To reset, tap the M-button once. For stations AA903 and AA905, press down the privacy switch temporarily. The privacy switch can be in any position,- black or orange plate. Station in Idle When station not in use, the LED is blank. Display station: In the display, the ID TEXT is the idle info. To scroll for CALL NO and TIME, press the scroll keys. To toggle 12 and 24 hrs., press the "T" button Loudspeaking Allows any subscriber to direct a conversation in loudspeaking (voice switching duplex) mode. The duration of a conversation is by default unlimited, but can be restricted using the service terminal (SVT programming). This applies to any conversation, loudspeaking or confidential. Display station: When making a call, the numbers dialled are shown in the display. When connected, the called stations's ID TEXT is displayed. Receiving a call, the caller's ID TEXT is displayed. To see the CALL NO and TIME, use the scroll keys. To adjust volume, press volume keys or . The station has 16 levels, indicated by 5 strokes in display. Manual speech control/ T-Simplex mode When calling to or from exceptionally noisy areas, a user can press down the T-button, to obtain manual control of the speech direction. Simply press the Tbutton to talk and release to listen. Either party may use this feature at any time during a call. If one party in a conversation has pressed his T-button and then the other party presses his T-button, the rule is that the last one who presses his T-button overrides the first. To revert to handsfree, tap the T-button for less than 400 ms. This feature does not function over tie-lines or between stages in multi-stage configurations. Confidential At any time during a call, either one or both of the parties can pick up their station, pressing the handset key, and use the set in the same way as a conventional telephone handset, to carry out a confidential (softspeaking) conversation. As soon as both stations in a connection are used in this mode the system operates in full duplex, that is, both parties can speak and listen simultaneously as in a conventional telephone conversation. To revert to loudspeaking, press the handset key again. Privacy Any subscriber in the system can block incoming calls by switching the station into privacy mode. Station AA916: press both scroll keys simultaneously. Station AA960: dial the feature code for privacy (default F1 or 951). Stations AA903/AA905: slide the privacy switch on the station (exposing a bright orange plate). Privacy has no effect on outgoing calls. The system has 2 different privacy modes: Privacy A: Subscriber B switches his station to privacy mode. Subscriber A calls B. B hears a short privacy tone (warbling tone). A hears a “ringing tone” (as a telephone) for about 12 secs. To accept the call B can press 0-button within 12 sec., A and B get a warning tone and a normal conversation is set up. If B does not press 0 within 12 sec. then A is cancelled. 21 System CB901 Features When the call is cancelled, B remains in privacy as long as the station is in privacy mode. Privacy A is provided as default in the system. Privacy B: As in mode A, except that the tone in both stations is a “ringing tone” (as a telephone) which is heard in both stations for about 12 seconds. Privacy B is individually programmable to any subscriber in the system. Stations can be programmed to NEVER be in privacy, or ALWAYS in privacy. The selected privacy mode is ignored. Valid to both privacy categories. Display station: To activate the Privacy mode, press the function key F plus 1, F1 (or the default code 951). PRIVACY is displayed. To open for incoming calls again, dial F1 again (or 951). Calling a station in privacy mode, the text PRIVACY, called station's ID TEXT and CALL NO auto scroll. In the receiving station, the LED lights red and CALL RQ (call request) caller's ID TEXT and CALL NO autoscroll. Ring-Master Service Terminal. Display Station: When hurry up is activated, the text HURRY UP will be displayed in the called station. The LED flashes red. Alarm Feature Two separate alarm channels can broadcast high priority information (such as hazard warnings etc..) to all stations in the system. The feature is implemented completely in hardware, there is no software control. Triggering of the alarm channels (dry contact), and content of the alarm message is sent via external equipment (e.g. tape recorder etc.). Both alarm channels have priority over programme distribution channels, All Call, Group Calls, privacy and busy stations. Furthermore, alarm channel no. 1 has priority over alarm channel no. 2. Any existing connections are not cancelled, the alarm is superimposed over existing conversations. Camp On A caller can automatically camp on to a busy station for a maximum of 15 seconds. If the extension becomes free within this period the caller will be automatically connected, otherwise the caller is automatically cancelled. If several parties try to camp on to the same extension, the second will get a busy tone for two intervals and then be cancelled. This indicates that someone else is in front in the queue. There is no restriction on camp on in the system,- only link capacity. Display Station: Calling a busy station, BUSY, the called station's ID TEXT and CALL NO are displayed, the 3 windows autoscroll. In the called station, CALL RQ (call request), the calling station's ID TEXT and CALL NO will autoscroll. The LED flashes red. Multichannel Programme Distribution Any user can dial into any of a max. of 8 programme channels (e.g. background music, radio programmes etc.) and select the desired output volume. The following sequence must be followed to initiate a programme channel: - First dial the feature code (default 98) - Dial digit 1 to 8 for the required channel - Dial digit 1 to 4 for the required volume The desired programme channel is connected. To change programme or volume (or both), dial the code (no need to dial X to cancel first). To cancel a programme channel, press X. The programme channel will automatically be suspended if the station is called or makes call, but is restored when the call is cancelled. Display Station: The ID TEXT for the selected program channel will be displayed. To step the channels, press a preprogrammed feature code (default F9 or 949). Hurry Up When calling a busy station, the caller can indicate that he is waiting by injecting a “hurry up” tone in the busy station. A is connected to B. C calls A. When the caller C gets the busy tone, he can press 0 button within 12 secs. and the hurry up tone is heard in A. If the connection is finished within 12 secs. then C is connected to A and both A and C get a warning tone. If the conversation does not finish within 12 secs, then C can press 0 again (and subsequently as many times as required) to obtain the 12 secs. “camp on” (each time C presses 0 an auto timer is reset). All stations have access to hurry up, except priority stations, which will cancel the blocking conversation. It is possible to enable/disable the feature via the 22 Data Transmission Allows a subscriber to communicate via DTMF with a device which is driven by DTMF tones (e.g. remote control device/decoder). The user calls the remote control device (which is assigned an access code). Any subsequent key pressed will be converted to DTMF and transmitted to the receiver. The call is cancelled with a feature code. The position of all remote control stations in a system must be programmed with the Service Terminal, otherwise the system assumes these positions are connected to a standard intercom station. System CB901 Ring-Master Direct Access Some substations have only a single push button (for alarm, ring, door etc.). When subscriber A pressing this button a call or a call request is made to a preprogrammed receiver B. This feature applies to stations with “CALL” button (e.g. AB921/AB921-F/AB931/AB931-F/AB931A/AB931A-F or specially modified stations). This feature also applies to the Master Display Station AA960, the Alarm Input feature. There is no limitation to the number of direct access stations in the system. There is no limitation to which other station the call gives access to. If the receiving station is in privacy, and does not answer with the 0-button, then the system can automatically (after 15 secs or the timeout is programmable with the SVT programming software) send a paging output and then cancel. This is valid if the receiver is programmed with paging feature. If the receiving station is a Central Answering Service (CAS) station then the caller will hear a ringing tone until answered. When a direct access station is programmed with a special “always page” privilege, then pressing the Direct Access button always results in a pager output. This can also be combined with the privilege preprogrammed pager data, then this data is sent to the pagers’ display instead of call number. Features Example: Programming the sequence: F* 1 3 1002 X will put call number 1002 on key 3. F* 3 5 1204 X will put call number 1204 on key-combination F plus 5, (F5). Display Station: The feature code to start programming the keys is F* (same as 914). The following info text is displayed: TABLE - KEY NO - NUMBER. . Priority Stations can be defined as “priority” stations enabling them to override a called station which is busy in a conversation or in privacy, resulting in a duplex connection with the called station. The priority station receives the busy tone, then dials 0. The existing call is cancelled and the priority station is connected to the called station in a normal duplex conversation. Connections set up normally (without using “0” option) can be cancelled by other priority stations. Connections set up by use of priority cannot be cancelled by other priority stations (the connection has “priority status”). There is no limit to the number of priority stations in a system. Priority stations must be programmed using the Service Terminal, otherwise no station has priority. Priority cannot cancel a conference call or a callconnection in progress. At any time during a normal call, a connection can obtain a “priority status” when one of the priority callers presses 0. Direct Dialling It is possible to program keys 0 to 9 and F0 to F9 of the AA960/AA961 stations' keypad to dial 20 frequently used numbers (call numbers or feature codes) with one/ two key-stroke(s). When a programmed key is pressed, a dial tone is heard as normal. If no other key is pressed within 1 second, then the programmed number is automatically dialled. If a second key is pressed within 1 second, then a normal dial sequence can take place. Programming: Programming of the direct dialling data, relevant to the different keys, can be made both by the station itself or from the SVT central software programming. To program the Direct Dialling feature, dial the feature code F* (or 914). Then dial the table number 1 or 3 (1 for keys 0 to 9,Fand - 3 for key-kombination F plus keys 0 to 9 plus 9) followed by the key number (09) and the required data (call number, feature code etc.). In the display the following info text is displayed: TABLE - KEY NO - NUMBER. End programming with the X key. All Call Allows general simplex messages to be broadcasted to every station in the system. The All Call is initiated by an authorized subscriber dialling the all call number. If an All Call is cancelled with 8 (instead of X) one answer back can be made to the All Call initiator by dialling 90 (no time limitation). If the initiator presses 90 first, the reply feature is cancelled. Any call number can be programmed as access number for the All Call. Only preprogrammed stations in the system have access to the feature, but any call number can be given this possibility. Any call number can be programmed to have the “all call x-out” function. A receiver of All Call with this privilege can cancel the incoming all call message by pressing the X-button. The duration of the All Call is standard limited to 30 seconds, but can be changed with the Service Terminal. 23 System CB901 Features Programming of All Call access code, and stations with All Call initiative access, is Service Terminal programmable. There are no default All Call numbers. If the feature is not programmed, this feature is disabled. It is possible to program “restricted All Call”. This means that any one group (as in Group Call, next section) can be excluded from the All Call (“negative group”). As there are up to 64 groups in the system, there can be one All Call per negative group plus one all call for all groups, giving max. of 65 all call access groups. An All Call overrides all other calls in the system except alarm channels. Existing calls at the time of the All Call are not cancelled. Only one All- or Group Call can be made in the system at the same time. Display Station: In the station initiating All Call, the remaining speech TIME will be displayed, (count down). Ring-Master Display Station: In the station initiating group-call, the remaining speech TIME will be displayed, (count down). Hunt Each station in the system is allowed one Hunt number to which the central automatically hunts if the station is busy or in privacy. Several stations can thus be linked together, so that the search continues until a free station is found. The search stops after a maximum of 10 hunts have been made. The search also stops if the hunt returns to the caller before 10 hunts have been made. All members of a group hunting and a chain identifier must be programmed with the Service Terminal. If the facility is not SVT programmed this feature is disabled. Display Station: In the calling station the user will see HUNT, the CALL NO, the ID TEXT and CALL NO for the hunted station. All 4 windows will scroll, window no. 2 (called number) will flash fast. If Advanced Display Info privilege is not programmed for the subscriber, window 1 (HUNT) and 2 (CALL NO) will not be displayed. Group Call Allows a subscriber to call a group of stations in the system, with a single code access, and to broadcast a simplex message. The Group Call is initiated by an authorized subscriber dialling the group access code. If a Group Call is cancelled with 8 (instead of X) one answer back can be made to the Group Call initiator by dialling 90 (no time limitation). If the initiator presses 90, then the reply feature is cancelled. The system can have up to 64 Group Call groups. Any call number can be programmed as access number for the Group Call. Only preprogrammed stations in the system have access to the feature, but any call number can be given this possibility. There is no limit to the number of members in each of the 64 groups, and a call number can be member of up to 64 groups. The duration of a Group Call is standard limited to 30 seconds, but can be changed with the Service Terminal. Programming of Group Call access codes, and stations with Group Call initiative access, is Service Terminal programmable. There are no default group call numbers. If the feature is not programmed, this feature is disabled. A Group Call overrides all other calls in the system except alarm channels and all call, but no existing calls are cancelled. Any one of the 64 groups can be a “negative” group in an All Call, so that the All Call includes all subscribers in the system except those in the specified group. Any call number can be programmed to have the “group call x-out” function. A receiver of Group Call with this privilege can cancel the incoming Group Call message by pressing the X-button. Conference Bringing in one at a time, anyone can dial up to 4 other extensions to set up a minimum of 3-party, maximum 5-party conference call (5 is default). Subscriber A dials B and a connection is established. A then dials C and a 3-party conference is established. A can similarly dial up to 2 more subscribers. The conference can proceed either in hands free or confidential mode, and the called extensions can freely leave the conference at any time. Only the initiator to a conference can bring in new members to the conference. The initiator can disconnect the last called extension by pressing X once. Pressing once more, the next (backwise) will be cancelled. Pressing X twice within 1 second cancels the complete conference call. Any called extension may freely leave the conference call by pressing X. When anyone is joining or leaving a conference, the initiator will hear a warning tone. All stations can set up a conference. A maximum of 8 conference calls can take place simultaneously, or limited to the link capacity (30 timeslots). A priority station cannot cancel a member of a conference call. If all stations in a conference call are used in confidential mode, the call is still in voice switching mode (not in full duplex as in an ordinary call). If any of the conference parties uses the T-button for Simplex mode (or to interrupt a conversation between 24 System CB901 Ring-Master two others) this station will be heard by all the others. When the T-button is released, the conference goes automatically back to duplex. The feature is enabled/disabled from the Service Terminal. The maximum number of participants in a conference (3 - 30) is terminal programmable, the preprogrammed figure is 5. Display Station: In the station initiating conference, CONF will be displayed. In the receiving stations, CONF, caller's ID TEXT and CALL NO will autoscroll. Features dialling F6 or 913 as a prompt for the optional call number. Display Station: To activate the Call Forward feature, press F5 (same as 910 in mode 1). CALL FWD and TO NUM will be displayed. Dial the call no to forward to. The display will show, CALL FWD and forwarded CALL NO. When calling a forwarded station the display will auto scroll: CALL FWD, the called CALL NO, the ID TEXT and CALL NO forwarded to. Window no. 2, the called number will flash fast. To cancel the call forward, press F6X (same as 913X). If Advanced Display Info privilege is not SVT programmed for the subscriber, window 1 (CALL FWD) and 2 (CALL NO) will not be displayed. Call Forward This feature gives a subscriber A the ability to route an incoming caller C to another station B. There exist 3 types of call forward: Mode 1. At own station A, transfer A to another station B. At own station A, forward A to another station B. A dials the facility code F5 or 910 plus B’s call number. This feature code can be dialled either when station is in idle (no call established) or while in duplex connection. A short acceptance tone is heard in A’s set immediately. From then on, short information tones (repetitive) are heard in A station at intervals of 5 minutes. Any call to A will now be routed to B. Mode 2. At another station B, transfer A to B. At another station B, forward A to B. B dials the facility code (911) plus A’s call number. A short acceptance tone is heard in B’s set immediately. From then on, short information tones (repetitive) are heard in A station at intervals of 5 minutes. Any call to A will now be routed to B. Mode 3. At another station B, transfer A to C. At another station B, forward A to C. B dials the facility code (912) plus A’s call number and then C’s number, (C’s number must be dialled within 12 seconds). A short acceptance tone is heard in B’s set immediately. From then on, short information tones (repetitive) are heard in A’s station at intervals of 5 minutes. Any call to A will now be routed to C. The repetitive information tone (every 5 min) can be disabled at any time after the transfer by switching the set to privacy. More than one subscriber is allowed to forward to the same station. To cancel the call forward: 1. Dial F6 or 913 from A’s station (followed by X or wait 5 seconds). A’s station then receives a short hurry up tone as an acknowledgement. 2. Dial F6 or 913 999 from B’s station followed by A’s number (within 5 seconds). B’s station then receives a short hurry up tone as an acknowledgement. In both cases 1 and 2 a hurry up tone is heard after Secretary Transfer This feature transfers calls initiated to the boss over to the secretary. Unlike CALL FORWARD the boss and secretary can confer in full duplex while incoming caller is kept on hold. The secretary number for the boss is programmed using the Service Terminal or by the boss dialling the feature code. The feature code for both is 935 and to cancel the feature again, 936. Caller A calls to the boss, but instead a connection between A and the secretary is established, (both get warning tones). When the secretary presses the 0button, A is put on hold (A gets a short privacy tone and then no audio, but the station remains on). The secretary establishes a full duplex connection with the boss (both get a warning tone). The secretary can now toggle full duplex conversation between boss and caller A by pressing 0-button. Each time the secretary presses 0, a full duplex conversation is established, both parties get a warning tone. The remaining party gets a hold tone if he is the caller A, or is simply cancelled with no tone if he is the boss. There is no limit to the number of times the secretary presses 0. If A cancels while on hold, no further connection can be made between secretary and caller A, using the 0button. The secretary puts the incoming caller A through to the boss by pressing X instead of 0 while in duplex connection with the boss. This causes the secretary to be cancelled (no tone). The caller A and the boss get warning tones and a full duplex connection is established. If the boss does not wish to accept A’s call, then he can press X while in full duplex with the secretary, or the secretary can press X while in full duplex with A. Several stations can forward to the same secretary. 25 System CB901 Features Display Station: To activate the Secretary Transfer feature dial the feature code 935 on the Boss' station. SECRETRY and info text TO NUM will auto-scroll. Dial the call number for the required secretary. In the calling station, the caller will see the following 4 windows auto-scroll: SECRETRY, the boss' CALL NO, secretary's ID TEXT and NUMBER. When the secretary is routed to the boss (caller on HOLD) the display will autoscroll SECRETRY, boss' ID TEXT and NUMBER. Ring-Master The feature code 941 8 is used to stop the memorising. Last callers redial is restricted to ordinary incoming calls and calls to stations in privacy. Using a non display station, the subscriber can only dial the feature code 941 and a call will be established to the first call logged in the queue. If the station is a Display Master Station (AA960 or AA961) the user can see the queue of calls in the display and scroll the queue to search for specific call numbers. The following codes (digits) are used to display the queue: Call Transfer Subscribers in the system can call a certain number (the transfer centre) and request for connection to another extension. Subscriber A calls B (the transfer centre). A asks for a connection to subscriber C. B dials the feature code followed by C’s number. All three stations are now connected, but there is only audio connection between B and C (A is put on hold and gets a continuous hold tone). The transfer centre (B) can now establish a connection between A and C and leave the connection by dialling X. If the transfer centre (B) decides not to make the connection between A and C, he dials the feature code and C is cancelled, and B is reconnected to A. The feature is provided as default, but can be disabled using the Service Terminal. The default feature code for Call Transfer is 916. Display Station: To activate the Call Transfer, dial the feature code 916. TRANSFER and TO NUM is displayed. Dial the call number to transfer to. Last Number Redial A subscriber can initiate “Last Number Redial” by dialling a feature code. Last number redial is restricted to ordinary calls, group calls, all calls and calls to a CAS (Central Answering Service) group. This feature is provided as default and can be disabled using the service terminal (SVT programming). The default feature code for Last Number Redial is F2 or 940. Display Station: To activate Last Number Redial, dial F2 (or 940). 941 1 displays first call number in queue. Display shows CALL NUMBER then digit 3: view next in queue. Display shows CALL NUMBER digit 2: view previous in queue. Display shows CALL NUMBER digit 1: view first in queue. Display shows CALL NUMBER digit 7: delete current entry, and display next in queue. Display shows LASTCALL, EMPTY digit 0 or F: to accept entry, establishing call to the displayed number. 941 5 disables the Call Last Callers information display in idle station. Display shows LASTCALL, DISPLAY, DISABLED 941 6 enables the Call Last Callers information display in idle station. Display shows LASTCALL, DISPLAY, ENABLED 941 7 deletes the Call Last Callers queue. Display shows LASTCALL, EMPTY 941 8 disables the Call Last Callers feature for this station. Display shows LASTCALL DISABLED 941 9 enables the Call Last Callers feature for this station. Display shows LASTCALL ENABLED or activate Call Last Callers with a function key,dial F3. Paging Allows a caller to page an absent subscriber. The caller can select several different paging modes to give different display information to the paged receiver. Subscriber A calls B and a duplex connection is established. A dials 8 (or 8 followed by additional information within 2 seconds). If a paging channel is free, then A is cancelled and gets a warning tone. If all paging channels are busy, then neither the A nor B connection is cancelled and the paging can be repeated. Call Last Callers Any subscriber can re-establish a connection to the last 10 callers by dialling a feature code, code F3 or 941. To start memorising the 10 last incoming calls the subscriber must use a feature code, code 941 9. 26 System CB901 Ring-Master The following paging features can be activated: 1. Initiator’s call-number in display. To activate paging, cancel the call with 8. A preprogrammed beep tone is heard in the receiver, and the caller’s call-number is displayed. 2. Preprogrammed individual message in display. Each subscriber can be programmed to transmit a prefix message to the called person’s pager. This message (alpha numeric) will be displayed instead of the caller’s call-number. 3. Preprogrammed system message in display. In addition to one of the above features, a subscriber can transmit a preprogrammed system message to the called person’s pager. 10 different system messages (alpha numeric) are available (0-9). To activate such type of paging, cancel the established call with 8 followed by the number (0-9) indicating the required system message. In addition, digits dialled on the intercom station’s keypad will be added to the end of the selected system message. Note that a position with no station attached is always in privacy, and can be used for users who only have a pager and no station (“dummy numbers”). See feature “Dummy number and auto-paging). The system has two “pager alarm” features. Dialling an alarm feature code, a special pager is activated and preprogrammed data is displayed. Features group. If the call has been offered to all available operators, and none of them accepted the call, the call will be routed to a hunt number instead. There can be max. 40 CAS groups in a system. There is no limit to the number of operators per group. Once in full duplex, no other features are available (except alarm, All-/ Group Call override). The feature must be programmed using the Service Terminal, otherwise the feature is disabled. Once logged in, it is possible to log in/out using the privacy function. The CAS operator will have a 2 second delay (programmable with SVT) between accepted calls, this to be able to initiate outgoing calls. Display Station: CAS mode 4 is used when operating with the display station AA960/AA961. The CAS call will be presented in all onlogged operator stations simultaneously, (in parallel). When an operator is logging on to a CAS group, ONLOGGED will be displayed. Calling a CAS number, CAS CALL will be displayed in the calling station. In the CAS operator station, the display will auto scroll how many callers in queue and ID text and call number for the first entry, ( QUEUE 3, ENTRY 1, ID TEXT , CALL NO.) To see the next caller (entry), press digit 3,6 or 9 on the station's keypad. To display the previous entry, press button 1,4 or 7. To accept the selected entry, press button 0 or F. Central Answering Service (CAS) A number of stations can be programmed in a linechain function for simultaneous central answering service with automatic queuing of incoming calls. A station which is defined as a CAS operator can log on to a CAS group by dialling the feature code and the call number to the group. Several such stations can log on to the same CAS group. The default feature code is 928 for log in and 928X for log out. If a subscriber calls a CAS group, and no one is logged on to this group, the subscriber is routed to a hunt number instead. If there are operators logged on, the first call to the CAS group will be offered to the operator that first logged on. The second call to the second operator, and so on. The caller will hear a ringing tone, or is connected to a program distribution channel, until the operator answers. The operator that gets a call will hear a ringing tone. This tone lasts for 15 sec’s during which time the operator can accept the call by pressing the 0button. If he accepts, a normal duplex conversation will be established between the caller and operator. If the operator does not accept the call, i.e. presses the Xbutton, or not accepts before the 15 sec’s timeout, the call will be offered to the next free operator in the CAS Call Back When a busy station is called, it is possible to dial a feature code, and have the system “call back” when you and the called station both are free. In the meantime you are free to make other calls. The default feature code is 8. When both stations are free, the initiator hears a special call back tone for 12 seconds. This is the warning that the called station is now free. If a connection is wanted, press the feature code (8) during the tone period and a normal connection is established. If the call is not wanted, no code is pressed, and the feature is auto-cancelled after 12 seconds. There is no limit to the number of call backs in the system and several stations can be queued up on the same extension number. This feature is not available when calling to stations with device type: CENTRAL ANSWERING SERVICE. Display Station: In the calling station, when the called station is free, the text CALLBACK and the called stations ID TEXT and CALL NO will auto scroll. The LED will flash green. 27 System CB901 Features Call Reply When a station is called, but without reply, it is possible to dial a feature code, and leave a message in the system that you want “call back”. The default feature code is 915. Subscriber A calls B, and when in duplex connection A dials the feature code. The connection is autocancelled and in the B station a short tone is heard every 5 min. When the B subscriber is back at the station, and hears the tone, he can dial the feature code (915) and is automatically connected to subscriber A, (both get warning tones). There is no limit to how many subscribers that can leave a message at the same station, or to different stations. The feature is general to the system and is programmed with the Service Terminal. The standard feature code i 915. Display Station: To activate Call Reply, dial F4 (same as 915). In the station where Call Reply is activated, the text CALLRPLY, DIAL and 915 will autoscroll. Ring-Master celled after the tone and the initiators’ call number is shown in the pager display. Please, see feature “PAGING” for details regarding various transmission alternatives. The feature is programmed by the Service Terminal. Open Station This feature allows a subscriber to rcall a busy station (programmed with the open station privilege) and set up a conference call. Subscriber A calls B (the open station) and a normal duplex connection is made, both A and B get warning tones. Subscriber C calls B and a 3-way conference is set up, both C and B get warning tones. Subscriber D calls B and a 4-way conference is set up, both D and B get warning tones. The call is cancelled the same way as CONFERENCE where in this case subscriber B (the open station) leads the conference. The maximum number of participants in the conference is Service Terminal programmable, with the default of 5. Display station: Calling a open station position, the text OPEN and the called position ID TEXT and CALL NO auto scroll. Sectoring The CB 901 system can be divided into independent sectors. Each station can be programmed with the Service Terminal to receive, transmit or receive and transmit to any combination of sectors. The system has 32 sectors. Any station in the system can be member of several sectors. Each station can be individually programmed to have access to call into another sector, and access to receive calls from any other sector. All sectors are Service Terminal programmable. As default, all extensions can call and receive calls from the first sector (sector no. 1) when the system is initialized. This means that with no programming of sectoring information, any caller in the system can call to/receive from all other callers. Direct Conference Dialling Some stations (programmable with Service Terminal) can be given access to initiate a conference call by dialling a feature code plus the required conference group. The system has a maximum of 10 preprogrammed conference groups (0 - 9). As a normal conference call, there are max. 10 participants as default in the system. The feature code is 937 + conference group (0-9). There is no warning tone on the receiving side, and the receiving stations cannot cancel with X. Dialling X on the initiator station cancels the whole conference. If a subscriber tries to initiate a direct conference call, but one or more of the conference participants are busy in another call, the initiator will receive a busy signal and no connection is made. Dummy Number and Auto Paging A line position can be programmed to status “dummy number”, no station connected. This feature is used when a person has no station in the CB 901 system, but it is required that it should be possible to page him, (give message to the pager’s display). Dialling the call number of a “dummy position”, the call will automatically be cancelled after approx. 2 seconds. A tone is heard in this 2 sec. period indicating that (if required), additional digits can be dialled for transmission to the pagers display. If no additional digits are pressed, the setup is can- Absence Registration (Display Station). The user has the possibility to "Absence Register" his station in two different modes, time- or date indication. To activate the absence registration feature, the user dials: - F0 (or the code 955). 4 digits must now be entered for time indication. - 956. 4 digits must now be entered for date indication. If the station activating the Absence Registration feature has a display ABSENCE - DIAL - TIME (or 28 System CB901 Ring-Master DATE) will auto-scroll in the station's display. If a subscriber, with a display master station (AA960), calls a station which is Absence Registered, the display will auto-scroll ABSENCE - TIME (or DATE) together with the called ID TEXT and CALL NO. To cancel the Absence Registration feature dial F0X (or 955X or 956X). The LED flashes orange. Features now be sent. Using a station with F-button, this button must be pressed to send the message. Different messages can be tested, when the right one is selected, dial F. If one of the last 5 messages is selected (5-9), digit information can be added. The additional digits will be shown in window no.2, following the fixed text in window no. 1. The info text in the display is: DIAL MESSAGE - DATA. The message is sent when the X-button is pressed. In the called display station the user will see four windows auto-scroll MESSAGE WAITING - DIAL - 958. To see the message text, dial the feature code 958. Use the scroll keys to read the windows. Dial the X key to delete the message. Message Display, (Display Station) The Message Display feature gives a caller the possibility to send a message string to be displayed on a display station. Additional numeric information can be added to some of the messages (messages 5 to 9) by keying the appropriate keys, e.g. "CALL-INT" - "12345". The system operates with 10 different messages. Messages 0 - 4 have fixed 16 characters, 2 windows: 0: CALL RECEPTN 1: CALL SWBOARD 2: CALL HOME 3: VISITOR LOBBY 4: Messages 5 - 9 have fixed 8 characters, 1 window and up to 8 digits can be added in window no. 2: 5: CALL INT XXXXXXXX 6: CALL TEL XXXXXXXX 7: MEETING XXXXXXXX 8: 9: A message can be sent i two different ways: Before a connection is established: The feature code 957 is dialled. The display will auto scroll the info: DIAL - NUMBER. Dial the required call number. The display will auto scroll the info: DIAL - MESSAGE - NUMBER. Dial the required message. If one of the first 5 messages is selected (0 - 4), and the user has a master station without F-button, the message will now be sent. Using a station with F-button, this button must be pressed to send the message. Different messages can be tested, when the right one is selected, dial F. If one of the last 5 messages is selected (5-9), digit information can be added. The additional digits will be shown in window no.2, following the fixed text in window no. 1. The info text in the display is: DIAL MESSAGE - DATA. The message is sent when the Xbutton is pressed. After a connection is established: When a connection is established , dial the feature code 957. The display will auto scroll the info: DIAL MESSAGE - NUMBER. Dial the required message. If one of the first 5 messages is selected (0 - 4), and the user has a master station without F-button, the message will Visicall Features. A Visicall station AE111 consists of a Visicall module plus an additional plug-in station AA904. The Visicall module has 32 direct dial keys. The Visicall module also has a 2 x 16 character display. Programming of the direct dialling keys and buffering of messages are internal features of the Visicall station. Caller Identification This feature informs a Visicall operator who is calling or is trying to call. There are two modes for caller identification: Mode A. If the Visicall operator wants to identify an incoming caller, the feature code can be dialled after the call has been established, and this will result in the caller’s call number being displayed on the Visicall display. The default feature code is 926. Mode B. There is no need to dial the feature code, the callers number always appears on the Visicall display after the warning tone. If the Visicall station (AA904) is switched for privacy, then the caller's number is displayed automatically, no need to dial the feature code (regardless of mode A/B). Message Display This feature gives a caller the possibility to cause a message string to be displayed on a called Visicall station. Additional numeric information can be added to the message by dialling the appropriate keys, e.g. “CALL EXTENSION” —— “6363” To transmit a message from any station to a Visicall station, first establish a normal connection, then dial the feature code followed by a number indicating the required message (0 - 9). The default feature code is 927. If numeric information is to be added, then this should then follow (up to 9 digits). Press X and the connection will be cancelled and the message ( and numeric info.) will be displayed in the Visicall’s display. 29 System CB901 Features The Visicall station can store up to 10 prerecorded messages and this feature along with the ability to read and delete these messages is an internal function of the Visicall station. If the Visicall station is in privacy, a message can be sent by dialling the feature code (927) within 15 seconds. If the Visicall subscriber accepts with 0-button while the caller transmits a message, a normal duplex connection will be established and the message will be displayed. Ring-Master - privacy - busy - reject (call not established) Each independent system is allocated an “area code” call number. There can be up to 10 area code numbers corresponding to 10 interconnected systems. This means that one system can call up to 9 other centrals. There can be up to 5 tie-lines between any two areas of centrals. In this configuration, by dialling the area code number, a group hunting sequence will automatically find the first available free tie-line. Speed Group Phone Book To simplify the dialling procedures for frequently used call numbers, the CB901 exchange can be programmed with abbreviated dialling numbers, consisting of two digits. If a display station is used, the caller can scroll the ID text for these preprogrammed numbers. Maximum 32 call numbers can be stored for each station (each phone book table) and a maximum of 32 phone books can be programmed in each CB901 system. The caller dials a feature code followed by the speed call number. The default feature is 923, but should be changed to a one digit code for easy access. Alternatively, the user dials FF (or 959) and the first ID text in the speed group phone book will be displayed. To display the other subscribers (totally 32 ID texts), the scroll keys must be used. When the required subscriber's ID text is displayed, press the F key to dial. Each system (any size) contains maximum 32 speed group phone books tables. Each such table contain 32 call numbers. A subscriber number in one slave stage can be member of a speed group phone book table in another stage. All call numbers must be entered using the Service Terminal, otherwise the feature is disabled. Voice Messaging, Absent Staff Registration (Multi-Svim) It is possible to store 24 seconds of voice messages. A separate printed circuit board can be installed in an ordinary subscriber position. The maximum length of the voice message is 24 seconds, which can be divided as follows by use of switches: - 8 messages of 3 seconds, - 6 messages of 4 seconds, - 4 messages of 6 seconds, - 1 message of 24 seconds, If more than 24 seconds are required, additional voice messaging cards can be installed. Recording of messages is carried out on site from any station in the system. When recording is completed, a switch is set on the card to secure the voice message memory. The function is now available for all subscribers in the system. The function is activated by utilizing the Call-forward feature. In other words, you transfer your station to one of the prerecorded messages. Each message has been given a fixed subscriber number. When calling this number you will hear the message, then press 99 and set your station in privacy mode. Anyone calling your station in your absence will receive the message you have chosen. When you return to your station, simply cancel the Call-forward function. ADDITIONAL FEATURES: 1: Individual messages. Some selected persons can be given the possibility of recording individual messages. The sectoring feature is programmed using the Multi Purpose Relay unit GH933. 2: Dynamic information channel. Any subscriber can call the actual “information number” and listen to a prerecorded message of up to 24 seconds. Intersystem Tie-Lines Two or more geographically separated Ring-Master systems may be connected by means of tie-line interface units coupled to each end of a rented or privately owned 4-wire telephone line. Dialling access to a tie-line will be prefixed with the digit 0, followed by a digit identifying the required remote central (1-5 digits), followed without pause by the local number of the desired station. There is no limit in the distance between installations. The line can be microwave, pcm or radio. The tie-line unit is connected to an ordinary subscriber position in the system. Only normal calls can be activated over the line. The receiving B-subscriber responds with: - answer (establishing a call) 30 System CB901 Ring-Master 3: Automatic autodialler with spoken message. By activating a closing contact (for example door station AB913) it is possible to send a message of 24 secs. to any predetermined subscriber number. 4: Delayed messages. One may call the predetermined autodialler number and talk for max. 24 secs, and the message will be recorded. Immediately after having cancelled, the autodialler will dial the preprogrammed subscriber number (for example the All Call number). The problem with feedback is avoided. Features grammed for each subscriber, Call Reply Time. If the paging receiver has no display, then this answering time must be programmed. If the paging receiver has a display, then this answering time is normally set to zero (default). The paging channel is therefore cleared immediately after transmission of the paging information. The answering time can be programmed from 1 to 12 minutes. One paging channel will be busy for each paging call, during the "wait for paging answer" period. If the page call is not answered within the programmed wait period, then the page call is automatically erased from memory. The system has 10 paging channels, thus accepting 10 simultaneous pocket page calls. The paged person must go to the nearest master station and dial 8 plus his own call number. A connection will then automatically be established between the station that made the page call, and the station from which the page call was answered. Public Address Interface Any public address system can be connected to the CB901 system by means of a special interconnection unit. Giving this interconnection unit a normal extension number, any master station can call this number to make an announcement. The group call or all-call facilities can also be used as public address. Two-way Mobile Radio Interface The CB901 system can be interfaced to a closed two-way radio network. Two interfaces are available: HD935 - no selective call. Any master station in the system can dial the call number dedicated to the radio interface unit HD935. This connects him to the radio network. All mobile units will receive the call and can reply. Simplex or duplex operation is dependent of the radio equipment, but speech control with the T-button is recommended. An incoming call from a mobile radio user will call up the base radio operator in the normal manner and cannot be transferred. The operator has to ask the wanted CB901 user to dial up the HD935 unit, which connects him to the radio circuit. HD938 - selective call. This unit permits for selective calling in both directions. Any CB901 subscriber can call any mobil radio unit directely and any radio unit can dial up any individually CB901 extension. Both units are connected to the CB901 system as an ordinary subscriber call number, 4 wires Telephone Interface An interface unit, HD939, can be supplied to operate between the public telephone network and the CB901 intercom exchange. The interface is used to make calls from any intercom master station to the telephone network and to make calls from outside telephones into any intercom station. Multiple interfaces can be used in the system. Each interface connects to one telephone line and requires only one station port in the CB901 system. Connections are established in full duplex loudspeaking handsfree mode. Radio Paging Interface The Paging feature can operate in combination with many of the other features in the CB901 central. The purpose of this feature is to transmit information to a radio paging system, including text that can be written in the display of a pocket receiver. The information can be transmitted directly when a specific number is called, or after some action in the calling station. The pager number can be from 1 to 5 digits, depending on the connected paging system. Via SVT a paging answering time can be pro- 31 Features 32 1 Display System CB901 Display features Feature: Display info at Power Up Ring-Master IDLE - Station not in use 2 How to use Display Stations Feature: Display info in the CALLING station Win. #1 Win. #2 LED Ring-Master LOUDSPEAKING/ SOFTSPEAKING Description: When connected, the ID TEXT is displayed.

Proper planning minimizes the time required and costs incurred during an installation. In the long term, maintenance, changes and expansions can be accomplished efficiently when planned for prior to the initial installation. This results in customer satisfaction and goodwill through a minimum disruption of their business activities. Ultimately, customer satisfaction results in additional sales. Each customer’s facility is different and requires a tailored approach to ensure that the job runs smoothly. Each facility will have its own combination of circumstances which must be addressed. The table below summarizes the major stages of a typical installation. The sequence in which the stages are accomplished might vary, the work involved in each stage itself can be modified to reflect the particular circumstances of each installation. The general approach, however, should include the following stages: STEP INSTALLATION 1. Site survey and data collection. 2. Plan major equipment layout. (Central, system power supply, and location of the various stations, speakers, etc. 3. Plan cable routing. 4. Prepare and pre-assemble the central and power supply at the shop facility. 5. Site work: a. Running of station cables. b. Equipment mounting (central, power supply, etc.). c. Installation of stations and speakers. d. System programming and adjustments. 6. System check-out and commissioning. 7. Customer introduction and training. NON STRUCTURAL CONSIDERATIONS: A. The central and power supply must be mounted on the wall or in a 19" rack. B. Location of the majority of stations, locate the central strategically, so that you can minimize the length of the cable runs. C. Location of existing telephone ducts or conduits. D. The AC line should be exclusively dedicated to the system. If the line is equipped with a circuit breaker at the service entrance panel, the circuit breaker switch should be labelled: “DO NOT TURN OFF” E. The equipment should be installed in an area that has adequate ventilation. A temperature range of 0 degrees C (32 degrees F) to 25 degrees C (77 degrees F) and a humidity range of 30% to 90% relative must be maintained. F. Appropriate lighting conditions and adequate working space should be provided for future service calls. G. Consideration must be given to those conditions that may cause damage to the equipment. For example, dust or vapour from flammable or corrosive solvent may cause damage, even so static electricity from carpets and plastic furniture, or direct sunlight. The installation site should not be located in an area likely to be flooded or likely to be damaged by moving objects nearby. H. The central should NOT be installed in an area near electrical noise producing equipment, such as heavy motors, welders, dimmers, radio transmitters, copying machines, etc. I. The power supply (or transformer) must be mounted ABOVE the central. This is to prevent overheating of the central. J. Check carefully that the central equipment has not been damaged during transport. Observe specially the pins on the flatcable contacts as well as the pins on the PCB’s. K. There are 4 screw holes in the cabinet for mounting on the wall or in a 19" rack. The installation cable can enter the cabinet at all 4 corners. B. Central Location A summary of the environmental factors affecting the Ring-Master CB901 system is presented in the listing below. These factors must be considered when developing a detailed system plan. Site preparation is dependent upon the customer’s facilities. In many cases there may only be one location where the central and power supply (or transformer) can be mounted. However, if there is a choice of location, the advantages and disadvantages of each location should be considered. 43 System CB901 Installation C. Cabling Requirements Each station is connected to the central by 4 leads (in two twisted pairs), 1 pair for audio and signalling and 1 pair for power supply. The 24V DC can either be supplied directly from the central, or a group of stations can be powered from a remote power supply. Ring-Master central must be increased accordingly. However, independent local DC power supplies can be used for distant stations. No reference wiring between local and central power supplies is necessary. IMPORTANT NOTE: If a number of stations are powered from a common/parallel DC power pair, voltage fluctuations can result in incidental crosstalk. Therefore it is essential that a separate power pair is always used for each station. If the output voltage of the power supply is adjusted for 27,0 V DC (recommended), this will give the following cable lengths at the indicated types of telephone cable used: 250 meter at 0,5 mm diameter copper cable 350 “ “ 0,6 mm “ “ “ 600 “ “ 0,8 mm “ “ “ 900 “ “ 1,0 mm “ “ “ If the actual distance exceeds these norms, it is recommended to increase the diameter of the cable (by using several wires), or to install a local power supply close to the station(s). Table with technical data related to the calculation of cable lengths: Normal voltage to the station (LA925/LA924A): 27,0 V Maximum voltage to the station: 28,5 V Minimum voltage to the station: 21,0 V Normal power consumption of the station: 100 mA Maximum power consumption of the station: 150 mA In the CB901 system, the following loop resistance values of the installation cable to the stations can be accepted: Max. loop resistance station wire pair no. 1, leads 1 and 2 = 240 Ohm Max. loop resistance station wire pair no. 2, leads 3 and 4 = 40 Ohm. Leads No. 1 and No. 2. Individual leads, i.e. a separate twisted pair is required for each station. Galvanically connected to KRONE subscriber terminal of flatcables BF927 in the central, these pairs carry tone signalling (CCITT norm) for dialling, audio transmission and DC control signals for stations. The maximum loop resistance of this pair is 240 Ohm, corresponding to approx. 2 km cable length from station to central, using standard telephone cable with 0,6mm diam. wiring. A longer distance (loop resistance more than 240 Ohm) can cause incorrect dialling transmission. If the cable to a station or a group of stations is running close to radio aerials or other interference sources, the leads should be shielded. Leads No. 3 and No. 4. These leads carry operating voltage to the stations. The maximum / minimum station voltage for proper operation is 28,5V - 21V. This allows a loop resistance between each station and power supply (centralized or local) of 40 Ohm, giving a distance of 350 meters on 0,6mm copper wire and 600m on 0,8mm. (based on power supply output of 27,0V). The above calculations are based on the average power consumption of 150mA per station and that the power supply is adjusted for an output of 27,0 V DC. The LA925 (LA924A for 110V AC) supplied by Stento ASA can be easily adjusted.
