CTP1000 Interface Module 100-to-25-Pin Cable Pinouts
The CTP1004 and CTP1012 devices provide 100-pin connectors for external serial interface
connections. The CTP1004 has one connector, and the CTP1012 has three 100-pin
connectors. This 100-pin output is on a quad cable (a Revision B or later cable ordered
separately) with the other end split into four standard DB-25 connectors, labeled
P0 , P1 ,
P2 , and P3 , connected to the serial interface. These port numbers correspond to the
port-numbering scheme implemented in the software configuration.
The pinouts for these connections have different configurations for EIA-530, RS-232,
voice, and T1 interface signals.
