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 private networked switch and be routed
across the private network to an extension on another system in the private
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 private
networked systems so that calls are properly synchronized. For details about
clock synchronization in a private network, see "Clock Synchronization" in
