Private Network Calling Problems
If you have a MERLIN LEGEND system Release 6.0, or if you want more
information about the Switch Type setting, consult the system Non-Local
UDP Administration Form in the Installation Specification. To see a report
including the switch type programmed for PRI facilities on your system,
select the
choose
of the Network Reference provides summary instructions for
determining the switch type programmed at your system and changing
it if necessary. The procedure for "Switch Type" in the "PRI Facilities"
section of Chapter 3 of System Programming gives full details.
If the call is carried over other systems connected by tandem PRI
facilities, the coordinating system manger must ensure that the settings
are correct, as in this example of MERLIN LEGEND Communications
Systems:
System A LEGEND-PBX
If the switch type settings are correct and problem persists, do one of
the following:
— If the call is a data call, go to Possible Cause 8.
— If the call is not a data call, call the Lucent Technologies Helpline
at 1 800 628-2888; consultation charges may apply.
Possible Cause 8: The FRL for the default COR for tie trunks (T1-emulated
voice or data, or analog) on the remote system may be blocking tandem calls.
The private network includes at least one analog tie trunk.
What to Do: Check with the coordinating system manager so that he or she can
determine where the problem exists. This may involve more than one system,
depending upon how your private network is set up. For example, a call might
be routed across the private network in a fashion such as this:
Origin System A
In this configuration, the coordinating system manager must check routes and
default COR attributes for Systems B and C.
