Maintenance and Troubleshooting
If the switch identifiers are correct and the problem persists, do one of the following:
I
– 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 Technical Support
Organization 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 MAGIX 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 MAGIX-PBX and System B can be set to MAGIX-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 MAGIX systems connected to it by tandem PRI trunks must specify MAGIX-Ntwk. If
the Interface field specifies User, the MERLIN MAGIX system facilities must be programmed with
the MAGIX-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. Run the PRI
Tandem Trunk Mode Demand Test by using the following procedure:

Back Back
Test Passed appears If the MERLIN MAGIX system at the other end of the PRI tandem
I
trunk is programmed in the opposite mode, the screen below appears.
Test Failed appears if the MERLIN MAGIX system at the other end of the PRI tandem
I
trunk is programmed in the same mode, or does not respond within the timeout, the screen
below appears.
If the system at the other end does not respond, the 100D module at the other end may not be
I
programmed for PRI, or the system at the other end of the PRI circuit may not be a MERLIN
MAGIX system.
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 MAGIX
systems:
System A LEGEND-PBX
