The Ameritec AM7 Central Office Simulator is a simulator of Central Office switches, PABX switches, or the Public Switched Telephone Network (PSTN). The AM7 is user-programmable, allowing realistic testing when an actual switch is not available. It is a self-contained, compact, lightweight unit which is easily hand carried, or can be rack mounted for laboratory use. The AM7 mainframe is a miniature, high performance, non-blocking digital switch. It is capable of switching up to 48,000 calls per hour, and has 10 option card slots for installation of plug-in interfaces. Interface options include: • 1 - 10 Analog Loop/Ground Start linecards • 1 - 10 Dual Line Analog E & M linecards • 1 - 4 Single Line T1 PCM linecards and/or Single Line DLC linecards • 1 - 7 Tone Receivers for decoding MF and DTMF digits for use with PCM or DLC interfaces The AM7 is easily configured to simulate a variety of CO or PABX switches. This allows testing to be performed in development or manufacturing environments without having to connect lines to a live switch. • The Analog line interface options for the AM7 make it perfect for testing of Customer Premises Equipment (CPE), particularly in development, manufacturing, and repair areas. • The PCM line interface option allows testing of CPE or switching equipment with T1 interfaces, and when used in combination with Analog linecards, allows the AM7 to simulate the subscriber and trunk functions of a switch. • The DLC option allows the AM7 to fully simulate a COT, making the AM7 perfect for installation testing of SLC ®96 Remote Terminals (RTs). The portability of the AM7 allows use in the field to test or install CPE or other equipment. The ability to remote control the AM7 via a built in RS-232 port makes it suitable for automated test applications in the laboratory.
