ABSTRACT To be able to give the most efficient and effective service as possible, having an organized and reliable telephone system is a must. With the current technological innovation, communications as a necessity have been continuously changing, improving every specification and virtually upbringing the fastest way possible for transactions. This paper intends to design a proposal PABX plan and layout for a two-storey college building. The design of the PABX system aims to divide and transfer incoming calls to a college department and help them connect their respective networks. One of its goal is to branch out the extension lines properly such that department and offices can communicate and share information effectively. In this branching, it includes the respective office local numbers and a helpful automated message. This documentation is composed of the essential files and data to support the viability of the proposed PABX design. Sanchez, Santisteban, Suarez ii PABX Design called private branch exchanges (PBX) . either internally or externally. including automated greetings. a PBX is the backbone of a corporate phone network. Since almost all private branch exchanges today are automatic. is a tool that connects all telephone lines in a workplace. If it is internally. Over time. it creates the connection between two users. And. Second. such systems . dialling menus. then the call will follow the internal call coverage settings. the PBX maintains the connections as long as the user requires the connection to be active. the receiver's coverage settings will be enacted. finally. PABX system. several advanced features were added to make PBX more efficient. voicemail connections. Basically. Third. Business networks utilizing a PBX have a number of lines or a T-1 digital connection coming into it to provide service and branches open connections throughout the enterprise. PBX systems provide four basic functions. among others. Suarez iii PABX Design . it disconnects users when the phone is hung up. Originally. the abbreviation "PBX" usually implies a "PABX. Small companies typically use multiple-line systems to handle their incoming and outgoing phone calls. it provides call logs and tracks usage. In simple terms." PBX stands for private branch exchange. Santisteban. If it cannot make the connection externally. In this scenario. it routes incoming calls to the right departments within the organisation.required the use of a live operator. PRELIMINARIES A private automatic branch exchange (PABX) is an automatic telephone switching system within a private enterprise. It also permits internal calling from extension to extension. First.III. four lines come into the business and are all visible on a multiple-line phone. which usually involves voicemail. Sanchez. and teleconferencing. letting their phone carrier handle the management of those lines. Suarez iii PABX Design . Santisteban.Sanchez. The area where the machines would be installed should be well protected all around from rain. Programming of the PBX machines . which enables callers to hear pre-recorded announcements or instructions. allowing them to reach the department they want to call.the PBX machine should be configured. switches. number plan. System Cards – These include devices for switching. and batteries that allow the system to run round the clock. Sanchez. Suarez iv PABX Design . lst of extension lines should be properly documented and stored safely. Wiring should normally sealed always. Steps to install a PABX system: 1. power connections and grounding must be checked and verified. If wires are not sealed. and power cards that facilitate the PABX operations. Grounding is very important for any PBX machines to work. Wiring for extension lines . The room should be dust free.One should always keep in mind for future enhancement and redundancy should be maintained. than probability of cable cutting or disconnection would increase. Power back. UPS (Uninterruptible Power Supply) – It consists of sensors. logic. It should be air conditioned area. Microcomputer – This is the central processing unit that interprets caller requests.The most essential parts required to set up a PABX system include the following: Switchboard – One common feature is the IVR (Interactive Voice Response). Santisteban. All required features. 3. control. Every extension should be numbered on MDF and stored for any future reference. 2. Survey the premise and make diagram . Sanchez. Suarez iv PABX Design . Santisteban. installation and wiring is very high. Cost of maintaining a PBX system is also high with trained people needed to maintain the hardware and equipment. Investments in the PBX system can be reduced over the years.Advantages: Multiple extensions can share cost of incoming phone calls. Disadvantages: Cost of setting up which includes equipment. Santisteban. Sanchez. Employees using mobile phones are not able to receive work related phones as PBX is not designed as such. Important add on features are quite expensive which results in escalating cost. PBX systems have started becoming aged as they work only within a centralized office. features extension and up gradation is possible. In high-tech expensive phone systems. Most PBX systems are rigid in case of flexibility of adding new extension lines and the need for buying new systems arises as business expands. With globalization. Suarez v PABX Design . Incoming calls cost is minimal and sometimes even free. Santisteban.
