DTMF Receiver Unit (BRCS-4, BRCS-8, BRCS-12)
There are three BRCSs: the BRCS-4 has four DTMF receiver circuits; the BRCS-8 has eight
receiver circuits; and the BRCS-12 has 12 receiver circuits.The BRCS is shown in
The B1CU can support up to 12 DTMF receiver circuits; all other processors can have up to 24
circuits. One BRCS can be installed on each processor PCB.
The DTMF receiver subassembly (BRCS) translates DTMF signals to data signals and attaches to
common control units with 4, 8, or 12 receiver circuits.
➤
To install an BRCS onto B1CU, B2CAU/B2CBU, B3CAU/B3CBU, or B5CAU/B5CBU
➤
Mate BRCS connectors (see
) with the applicable BCU PCB. Apply firm, even
pressure to the BRCS to ensure proper mating of the connectors. Connectors for each BCU
card are shown on
. One BRCS (4, 8, or 12) can be installed on each
processor, allowing up to 12 DTMF receivers on B1CU and 24 on all other processors.
Note
The BRCS connectors on these PCBs are positioned to allow installation of the BRCS
only in the proper position.
