Cabling a card with or without a termination panel

241-1501-200 5.2S2
The information about custom-made or prefabricated cable assemblies for a
plug-in card or a termination panels is provided with the description of each
control processor (CP) or function processor (FP) card. Each description lists
the optional prefabricated cable assemblies and includes the specifications for
type of cable and connector, and includes the port pinouts of the faceplate
connections.
In general, cabling a Passport card port to a termination panel port means
doing Tx-to-Tx and Rx-to-Rx connections for the entire end-to-end
connection path. You can also determine the appropriate Tx-to-Rx
combinations depending whether the signal is exiting one unit and entering
the other provided the pattern of combinations is the same for the entire end-
to-end connection path. When the Tx-to-Rx combinations get criss-crossed
between an FP, a termination panel, and the far-end termination, the effect of
one error nullifying another can establish a workable connection. It is
important that you label the connection information of each Tx and Rx
connection onto the end of the cable at each break in the cable path.
Specific cabling information for the plug-in CPs and FPs is included in
"Control and function processors" (page 141).
Specific cabling information for the fanout and sparing panels of the DS3
cards is included in "Termination panels for FPs" (page 291).
