Connect the cable wires to the proper pinouts on the RJ-48C connector on the D/240PCI-
T1 end of the cable. The pinout designation is shown in Figure 13. Consult your CSU
documentation for the proper pinout designation and connector type for the CSU.
You should also follow your CSU documentation concerning grounding the cable. CSU-
to-equipment cables are usually grounded at one end only. The CSU end of the cable is
grounded and the D/240PCI-T1 end of the cable is not. If it is required by the CSU, you
can ground the D/240PCI-T1 end of the cable by attaching the common shield to the
metal casing of the plug you are connecting to the D/240PCI-T1. This will provide
adequate grounding to the platform chassis when the cable is attached to a properly
installed D/240PCI-T1 card.

To cable D/240PCI-T1 linecards:
1.
Connect the T1 line–to–CSU cable to the CSU.
2.
Connect the grounded end of the CSU–to–D/240PCI-T1 adapter cable to the
connector on the CSU.
3.
Connect the ungrounded end of the CSU–to–D/240PCI-T1 adapter cable to the
RJ-48C connector at the back of the D/240PCI-T1.
4.
If the CSU requires that you ground both ends of the CSU–to–D/240PCI-T1 adapter
cable, attach the common shield on the adapter to the metal casing of the connector on
the D/240PCI-T1. This will provide adequate grounding to the platform chassis.
