Abacus PCG Digital Call Generator & Switch Simulator card with the following options: Hardware revision: 20 Rear card is included Call gen T1 CAS E1 CAS PRA SS7 The PCM Circuit Generator (PCG) subsystem provides one PCM circuit at the T1 (1.544 Mbps) or the E1 (2.048 Mbps) rate. The circuit can emulate a telephone exchange (central office) or a terminal. You can configure any of the channels to be an originating channel or a terminating channel (calling or called party). The PCG subsystem comprises the following two printed circuit assemblies: PCG: the front card, which has active electronics and is installed into the front of the shelf. PCI: the rear card, which has connectors and jumpers and is installed into the rear of the shelf to provides the physical means of connection to your system under test. Features One four-wire (full duplex) circuit Call generation and switching Built-in protocol analyzers Test T1 (1544 kb/s) and E1 (2048 kb/s) 32-bit processor, DSPs, and flash memory to ensure full computing and upgrading capabilities Standard ISDN protocols are supplied, and each standard protocol can be customized Programmable call progress tones Flexible call sequences Generate 20,000 calls or switch 13,400 calls Program test duration to be random or fixed from 1 s to 5 years Verify that speech path is established and retained for duration of call Results are automatically and continuously gathered and presented in tables and graphs End-to-end testing with other interfaces on Abacus1 NOTE: No software of any kind (external or internal) is provided with the Hardware.
