7. At the rear of the carrier, connect the appropriate DTE interface cable (EIA-232-D
or V.35) to the rear connector plate. For an EIA-232-D interface cable, connect the
EIA-232-D cable to the top DTE connector on the rear connector plate.
For the 25-pin V.35 interface, a V.35 adapter is shipped with the unit. To connect a
V.35 adapter to the 25-pin V.35 connector, perform the following steps:
— Connect the 25-pin end of the V.35 adapter to the bottom DTE connector of
the rear connector plate. Tighten the thumbscrews on each side of the
connector.
— Connect the V.35 interface cable to the 34-pin end of the V.35 adapter, then
tighten the screws on each side of the cable connector.

at the rear of the carrier. These interfaces are specified in the USOC RJ48T, and
the pin assignments are shown in Appendix D of the User's Guide. Proper network
connection to the DDS facility or to the network channel-terminating equipment
must be made at the far end of the cable.
