Centrex & PBX Demonstrator

49300 Centrex Demo
Model 49300

The Proctor Model 49300 Demonstrator enables realistic demonstration of Centrex and PBX station telephone equipment and call processing features, without using telephone company facilities or services. The unit demonstrates all major Centrex or PBX calling features, including station-to-station calls, call transfers, hold functions, conference calls, and CLASS services, such as Caller ID. In addition, the 49300 can demonstrate other types of phone products, like FAX, auto-attendant systems, voice mail, modems, and standard or cordless telephones. If a standard central office loop is required for a particular demonstration, the unit is equipped with a C.O. line jack for optional access to the telephone network. The compact, portable 49300 can be operated wherever standard AC power is available. Its modular quick-connect jacks allow a complete working demonstration to be set up or disassembled in a matter of minutes. The 49300 is equipped with a wide array of Centrex and PBX calling features that can programmed using a tone dial telephone or a PC running special software developed by Proctor. Programming customizes the 49300 for different applications and user requirements, such as different Centrex switch type emulation packages, custom call processing codes and telephone numbers for its four stations.

How It Works

49300 Schematic

The 49300 works just like a standalone miniaturized Telco central office. It provides dialing and ringing over its four simulated phone lines, and it includes a precision tone plant that produces authentic sounding call progress tones, such as dial, ringback, busy tones, etc. The user simply plugs the demo unit into the nearest standard AC outlet, plugs in the line cords of the four telephone devices and dials one of the other devices. The unit's four demonstration ports support two simultaneous phone conversations or data transmissions.
The 49300 can be programmed with special dialing and ringing codes that enable specific call features, ringing patterns and access to certain ports. It also enables user to select between 115VAC or 230VAC operation.
The 49200 can also be used to quickly check basic phone equipment functions, like the dial, ringer, line, etc.
