DID or PRI Dial-Plan Routed Calls Not Completed

DID or PRI Dial-Plan Routed
Calls Not Completed
Possible Cause 1: DID and PRI calls cannot be routed to a 5-digit DEFINITY
ECS or DEFINITY ProLogix Solutions system.
What to Do: Verify system programming and the digits received from the PSTN.
Refer to Chapter 5, "Non-Local Dial Plan Number" for details on programming
required.
Possible Cause 2: DID or PRI routing not correct
What to Do: The coordinating system manager should check the DID or PRI
routing. These calls may come into one networked switch and be routed across
the network to an extension on another system in the network. The routing must
specify the correct tandem trunk pools, extension numbers, and digit
manipulation.
If the routing is correct, contact the service provider. If the service provider
instructs you to do so, call the Lucent Technologies Helpline at 1 800 628-2888;
consultation charges may apply.
Excessive Line Noise on Voice and
Data Calls
Possible Cause: Clocks are not properly synchronized.
What to Do: The coordinating system manager should check error logs at
problem systems. If slips are occurring at a high rate or an alarm was raised, clock
synchronization is a problem. The coordinating system manager should then
check the programming for the PRI tandem trunk(s) and/or PSTN digital facilities
that carry the calls. A single clock source is used for all networked systems so that
calls are properly synchronized. For details about clock synchronization in a
network, see
synchronization, see Chapter 4 of System Programming .
If the clock source is correct, ensure that the specified port is functioning properly
and has an in-service facility connected to it.
If this does not solve or explain the problem, call the Lucent Technologies Helpline
at 1 800 628-2888; consultation charges may apply.
