Connections for Traffic Card Cables
All traffic card cables, with the exception of the DS-3 and E3 cables, are connected to the front panels of
the cards; DS-3 and E3 cables are connected to the rear of the chassis. See the “Traffic Card Cables” section
in Appendix A, “Cables and Pin Assignments,” for cable specifications.
Not all ports are enabled on a low-density version of a traffic card; low density traffic cards are identified
by the label on the lower ejector lever.
Table 4-3 lists the port data for traffic cards; in the table, ER, IR, LR, and SR abbreviations are used for
Intermediate Reach, Long Reach, and Short Reach, respectively.
