DTMF Receiver Subassembly (RRCS)
The RRCS translates DTMF tones from DID/Tie/ANI/DNIS/DISA lines, built-in AA, DTMF
standard telephones, and other peripheral devices to data signals for the system.
The RRCS can be attached to the common control unit and is available with either 4, 8, or 12
(RRCS-4, -8 or -12) shared receiver circuits. See

Printed Circuit Boards (PCBs)

PCBs are installed in the cabinets to provide interface for stations, lines, and peripherals. Each
PCB measures 7.5 x 5.5 inches (190 x 140 mm) and mounts in the slot with a 44-pin backplane
connector. PCB external connections to station equipment are made to the Main Distribution
Frame (MDF) using industry-standard connectors. For more details, see
Peripherals.
