3If you are connecting a supervisory console to the MultiMux, connect a terminal or PC to the COMMAND PORT connector via an appropriate RS232C cable. The PC must be running communications software.

Note

Any cables connected to the computer should be shielded to reduce interference.

4Apply power to the supervisory console and enter AT and then hit Return. If you get an OK message back, you are communicating with the Command Port. The Command Port operates at up to 19.2K bps.

Command Modem

5To connect the built-in command modem to a standard phone line, connect the RJ11 cable to the 2400 BPS MODEM DIAL-UP LINE connector on the back panel of the MultiMux and the phone jack.

Composite Link

6 Verify that the FC channel LEDs on the front panel flash on for a few seconds and then go out.

7Verify that the CD, RCV, XMT, CTS LEDs on the composite link (A or B) that you have connected are on and the RD LED goes off for that link. Proceed to configuring the Sync Data Channel or the Async Channels.

Note

This verifies that the composite link

is up and working.

If the RD LED stays lit, the composite link device is not configured to communicate with the link, configure the internal DSU. Proceed to configuring the composite link.

If the XMT and CTS LEDs lite for composite link A or B and the RD LED goes off, the remote mux is not powered on or the remote DSU is not configured for the composite link. Proceed to configuring the composite link.

9Based on the listed conditions for the composite links, reconfigure the parameters to match your actual composite link requirements by entering commands as described in Chapter 5.

As you change parameters, they will not actually be incorporated into your running system until you execute a Store New Parameters (&W) command.

Sync Data Channel - Port B only

10To configure port B as the Synchronous Data Channel, enter $MUXBSYNC command.

11Enter a Store Parameter (&W) command and then reset the MultiMux by entering a reset (Z) command or powering the MultiMux off and back on.

12Enter $L command again to redisplay the configuration. The display appears as follows:
