The connector pinouts for the optional four-port IMA expansion module are the
same as those for the standard T1/E1 UNI with IMA interface.
The following tables list the connector pinouts for the serial port interfaces (V.35,
RS-422, EIA530, and X.21).
PathBuilder S330/S310 cables are compatible with Cisco cables, except for the
DCE EIA530, which Cisco does not manufacture.
