Newsletter: GL Announces New and Enhanced Analog Phone Simulator

Welcome to the March issue of GL Communications' Newsletter providing information about new introductions in GL Communications' Digital and Analog Call Simulation Products.

The DCOSS APS (Analog Phone Simulator), converts a GL DCOSS (Digital Central Office Switch Simulator) into an analog phone simulator that simulates a bank of up to 384 analog telephones. Using GL's basic DCOSS with T1 interface cards and the new APSCB24/48 external channel banks, the DCOSS APS may be used to test a Central Office (CO), PBX, Gateway, or other telecommunications equipment, that uses local loop interfaces (RJ-11 type).

The figure below depicts the mechanism in APS:

All functionality currently associated with the DCOSS, including bulk calling, scripting, and remote client/server, may be used to control the APSCB24/48 2-wire analog ports. In addition to this functionality, all traffic supported by the DCOSS (Fax, Modem, Voice Files, DTMF/MF Digits, Frequency Tones) is also fully supported by the APSCB24/48 devices.

The DCOSS connects to the APSCB24/48 via a T1 (up to two T1's per APSCB24/48) and digital calls are generated to the APSCB24/48 using the DCOSS GUI. Each digital call signifies analog offhook with DTMF dialed digits from the APSCB24/48. Both outgoing and incoming analog calls are supported. The connection to the APSCB24/48 includes a standard amphenol connector, which can be connected to a breakout box that supports up to 24 2-wire interfaces. Each of the analog ports (up to 48 per APSCB24/48, maximum of 384 ports per DCOSS system) serves as an independent analog telephone, which can be individually configured and activated for various telephony tasks.
