CAB-RBBN-16T1E1 Cable Connector Pin Assignments

The CAB-RBBN-16T1E and CAB-RBBN-16T1E1-Y cable connectors pin assignments are shown
inTable B -32. In the RBBN card, Tx and Rx are separated into two connectors, and the cable is identical
for both connectors. That is why the table lists only tip and ring instead of TTIP/TRING and
RTIP/RRING.
