Installing the Model 3616 DualFlow DSU

7.At the rear of the carrier, connect the appropriate router 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 Interconnect Cable is shipped with the unit. To connect a V.35 Interface Cable to the 25-pin V.35 connector, refer to Figure 3-4 and perform the following steps:

a.Connect the 25-pin end of the DSU's V.35 Interconnect Cable to the bottom DTE connector of the rear connector plate. Tighten the screws on each side of the connector.

b.Connect the 34-pin end of the DSU's V.35 Interconnect Cable to the V.35 interface cable, then tighten the screws on each side of this connector.

8.The installed DSU is connected to the DDS network through the 50-pin connectors at the rear of the carrier. These interfaces are specified in the USOC RJ48T, and the pin assignments are shown in Appendix D. Proper network connection to the DDS facility or to the network channel- terminating equipment must be made at the far end of the cable.

9.If the network line and remote DSU are installed and tested, do a Remote Loopback ± a Test Pattern test.

10.If the Front Panel test switch strap is to be disabled, slide the DSU slightly out of the carrier, open switch S3-1, then reseat the DSU into the carrier. Do this now.

11.Circuit ID information can be written on the cover plate under the appropriate slot number.
