Possible Cause

A failure message
appears followed
by an 8-digit code
(

x x x x x x x x )

Internal DSU/CSU problem.

Record the 8-digit code, then
contact your service
representative.

Mgmt link is down

1. The manager configuration is

mismatched with the
DSU/CSU configuration.

2. The manager’s link layer

protocol is not running.

1. Check that the configurations

are matched.

2. Start the link layer protocol.

Test Jacks

Two test jacks are located on the front panel: Net Mon (Network Monitor) In, and
Net Mon Out.

Net Mon In nonintrusively monitors the signal going into the network.

Net Mon Out nonintrusively monitors the signal coming from the network.

Test Commands

The test commands enable you to run loopbacks and test patterns on the
DSU/CSU, and to test the front panel LEDs. These tests can help you isolate
areas of trouble if you are having problems with your DSU/CSU.

To access all Test commands from the Test branch, press F2 to select Test from
the top-level menu screen.
