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.
2. Connect the cable to an expansion module serial interface (Figure 1-11)
or an adapter module serial interface (Figure 1-12) .
Note: The Cable Guide refers to serial cables that transmit synchronous data
as “synchronous” cables.
