5.5.2 MODEM A & B (J7 & J11) G703/RS422 Serial Universal Interface
w/SCSI
connectors
The Modem Channel a Port is a 68-Pin High-Density Female SCSI Connector. This port is the
data interface used to connect to the primary and backup modems. This interface supplies the
RS422 Synchrounous, G703, IDR and IBS data information from the modems. Refer to Table 5-
5 for pinouts.
