*To enable stepdown (slower data transmission speed), set 4800 speed to ON. On the modem, set Options 50, 56, and 73 to y.

Continue the installation according to the following steps. The 7400A is configured for DTE modem pool operation with D-lead controlled 2296-type modems. The mounting package includes an adapter harness (WP90780L0), an OR-6316 bridging adapter, and a 2296 modem control cable (D- Lead).

13.Connect the 50-pin connector on the adapter harness to P1 on the bridging adapter [see Figure 11-6,AUDIX Networking (Modem Pooling) With 7400A DSUs]. Then plug each numbered connector (D8W-87 cords) on the harness into the LINE jack on the corresponding 7400A (see the numbered slots on the mounting rack).

14.Connect the 25-pair cable from the switch to J1 on the bridging adapter. For correct wiring of the switch cable, see the table titled WP90780L0 25-Pair Cable Adapter for Use with Direct Cabling to Multiple Mount for DCP Installations in the 7400A Data Module User’s manual.

15.Connect the 50-pin plug of the D-Lead cable to J2 on the bridging adapter.

16.Put the cover on the bridging adapter.

17.Connect the other end of the D-Lead cable to the Data Mode Control connector on the modem rack.
