The CTP150 device has five separate EIA-530 cabling options for the serial interface module, with a male HD-26 connector on the module end and the following connectors on the DCE or DTE end:
The pinouts for these connections have different configurations for EIA-530, RS-232, voice, and T1 interface signals.
Table 1 lists the EIA-530 interface signal pinouts for the HD-26 connector to the female DB-25 connector for the CTP150 platform.
