What Are the Troubleshooting Features?

The T1 access unit is designed to provide you with many years of trouble-free
service. If a communication problem occurs, however, refer to the information in
this chapter for possible solutions.
The T1 access unit can:
Detect and report faults
Perform diagnostic tests
Use the test jacks on the front panel of the Single and Dual T1 NAM, and the
DSX APM to help isolate problems.
Statistics are also collected to help you determine how long a problem has
existed. See Chapter 7,
Displaying System Information
, for information on
statistics.
These features ensure that your T1 access unit is giving you optimum
performance in your network.

How Do I Know There Is a Problem?

The T1 access unit offers three major mechanisms that alert you to possible
problems:
LEDs
Alarms
SNMP Traps
If monitoring the system, the System and Test Status screen can also indicate
that there is a problem.
