Connecting to a Serial Interface

You connect 44-pin serial cables to the connectors on ARN adapter and expansion modules. Each serial interface supports multiple WAN protocols at a transmission rate of 1200 b/s to 2.048 Mb/s.

To connect to the serial interface:

1.Locate the serial interface cable.

The serial interfaces automatically configure the desired electrical interface when used with standard keyed cables. For information about cables available from Nortel Networks, see the Cable Guide.

Note: The Cable Guide refers to serial cables that transmit synchronous data as “synchronous” cables.

2.Connect the cable to an expansion module serial interface (Figure 1-11) or an adapter module serial interface (Figure 1-12).
