Private Network Calling Problems
— If the call is being routed over any tandem PRI facilities, go to
Possible Cause 7.
— If the call is being routed over tandem tie trunks only, call the
Lucent Technologies Helpline at 1 800 628-2888; consultation
charges may apply.
Possible Cause 7: The Switch Type setting at both ends of a tandem PRI
facility may match.
What to Do: The coordinating system manager must check the programmed
Switch Type settings at private networked systems. Calls are not routed
properly unless the Switch Type setting is correctly programmed at the systems
on both ends of any tandem PRI facilities on the call route. If only MERLIN
LEGEND Communications Systems are included in the routing, the switch type
settings on the systems must be different. For example, if System A is
connected to System B by tandem PRI trunks, System A can be set to a switch
type of LEGEND-PBX and System B can be set to LEGEND-Ntwk. It does not
matter which system is assigned the PBX or Network switch type as long as the
switch types are different.
If a DEFINITY ECS or DEFINITY ProLogix Solutions system has its Interface
field set to Network, any MERLIN LEGEND Communications Systems
connected to it by tandem PRI trunks must specify LEGEND-Ntwk. If the
Interface field specifies User, the MERLIN LEGEND Communications System
facilities must be programmed with the LEGEND-PBX setting.
If the call is routed over a tandem PRI facility connected to your system,
ensure that the system at the other end of the facility is programmed
correctly to work with your own setting. Consult system Non-Local UDP
Administration Form in the Installation Specification. To see a report
