Spirent Abacus 5000 PCG3 PCG-3004BF Subsystem provides PCM circuits that can emulate a telephone exchange (central office) or a terminal. The PCG3  subsystem provides TDM call generation and switching functionality to test PCM T1/E1 circuits with 24 or 30 channels per circuit. Each channel can be configured as an originating (calling party) or terminating (called party) channel.
