Enabling the Communication Port for Carrier-Mounted DSU/CSUs
Communication between the carrier-mounted DSU/CSUs and an external PC,
ASCII device, SNMP manager, or async terminal interface (attached either locally
or through an external modem) occurs through a shared communication (COM)
port. (For COM port cabling information, refer to the
COMSPHERE 3000 Series
Carrier Installation Manual
.) Unlike standalone DSU/CSUs, the carrier-mounted
DSU/CSUs do not have a dedicated COM port for external access. Once the COM
port is enabled, other COM port configuration options can be selected. These
options are used to configure Port 2 on the Auxiliary Backplane as a COM port for
the carrier.
NOTE:
If a Model 3161 DSU/CSU has the COM port enabled, Port 2 cannot be used
as a data port.
Procedure
To enable the COM port on the carrier-mounted DSU/CSU:
1. From the top-level menu screen, select Cnfig.
2. Select the configuration option set to be copied into the Edit area by using the
appropriate Function key. Use the scroll keys, if necessary.
3. Select Edit.
4. From the Edit screen, press the
key until the User selection appears on the
screen.
