5. Check with your T1 or PRI service provider to see if through-fed repeaters are
used on the T1 or PRI span. The EE-DTM does not provide the DC
connection required for through-fed repeaters. If through-fed repeaters are
used on the T1 span, disable the internal CSU and connect the EE-DTM to an
external CSU.
6. If the problem persists, replace the EE-DTM.
For information on how to replace any system components, refer to the Enterprise
Edge Installation and Maintenance Guide

Monitoring the T1 or PRI signal

If you are finding minimal faults with the T1 or PRI signal, you can monitor the
signal to try and isolate the problem. The monitor jack on the EE-DTM faceplate
provides non-intrusive, bridged in-service monitoring of the T1 or PRI signal.
Connect a protocol analyzer or other test equipment into the monitor jack to monitor
the signal received from the network, and the signal transmitted by Enterprise Edge.

Problems with Trunk or Station Modules

1. Choose Resources, Media Bay Modules and the bus that the module is on to
ensure that the module is not disabled. For more information, refer to the
procedure,
2. Disable the module using the procedure,
3. Enable the module using the procedure,
4. For an EE-DTM, EE-CTM or EE-DSM:
Check the external line by terminating a single-line telephone directly on the
distribution block, or equivalent, which connects to the Trunk Module.
5. For the EE-ASM:
If the EE-ASM is still down, power down, then power up the Enterprise Edge
system.

Notify service provider of T1 or PRI signaling disruption.
Notify your T1 or PRI service provider before disconnecting your T1 or PRI
lines, removing power to your system, or performing any other action that
disrupts your T1 or PRI signaling. Failure to notify your T1 or PRI service
provider may result in a loss of T1 or PRI service.
