Eia-530 Connector Interface Signal Pinouts (Db-25 Female Dce) - Juniper CTP Series Hardware Manual

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:
Female DB-25 connector on the DCE end for EIA-530/RS-422/V.11, RS-232/V.24, V.35
Male DB-25 connector on the DTE end for EIA-530/RS-422/V.11, RS-232/V.24, V.35
Female DB-15 connector on the DCE end for X.21
Male DB-15 connector on the DTE end for X.21
RJ-45 connector for Radio V.24 Sync interface
The pinouts for these connections have different configurations for EIA-530, RS-232, voice, and T1
interface signals.
