ENGINEERING INSTRUCTIONSTRANSMISSION CPE STM1 EI NO. INSTALATION AND TESTING PROCEDURE OF CUSTOMER PREMISES EQUIPMENT STM1 ITI Make (TEJAS) 1.0 SCOPE: This Engineering Instruction provides Installation information and describes various tests to be conducted on CPE (Customer Premises Equipment) STM1 during commissioning. The system is manufactured by M/s TEJAS Networks, Inc. USA and supplied by ITI. 2.0 GENERAL: The equipment establishes a 622/155 Mb/s trans system whose high flexibility allows to set up various configurations mainly line terminal or insert/ drop multiplexer with protection option. The equipment can be plesiosync or synchronous i.e. 2/34/140 PDH tributaries or 155.520/622 Mb/s synchronous tributaries. The equipment can be configured independently in Mesh, Ring, linear and Bus architectures and also a mix of the above. Also it can be flexibly configured with equipment redundancy for all or for a selected few among the modules. The main features of the system is 1) Easy network manageability 2) Flexible configuration 3) Lower cost per line 4) Easy upgradeability 5) Support for both data and voice over SDH 6) Higher reliability 3.0 INSTALLATION: 3.1 Unpacking: First check the shipment container for any kind of damage and then unpack the equipment pack with upright mark always at the top, remove all shock proof materials, polyethylene packing and ascertain and confirm that no physical damage taken place and items available as per packing list. 3.2 Installation of the Rack: Installation requires fixing of Rack and mounting sub-rack structure in the rack. Drill hole on the floor to fix the rack. (Holes are provided in the base plate of the rack). Fixing of the rack is done by anchor bolt jammed by the help of plugging compound and ensures the verticality of rack. 3.3 E3 (34Mb/s) connection: The E3 (34Mb/s) traffic is received and transmitted through an interface (TE31) card. The connectivity is made through two BNC connectors (Tx & Rx). 3.4 Ethernet connection: The Ethernet traffic is received and transmitted through an Ethernet interface (TP01) card. The connectivity is made through an RJ45 connector. Connect the cable to RJ45 connector to the marked position and ensure that retention slide operates to hold the connector in place. 3.5 STM1 connection: (Optical) The STM1 optical traffic is received and transmitted through STM1 interface on the base card. The connectivity is made through an SC connectors (Tx & Rx).
