Private Network Calling Problems

Private Network Calling Problems
In Release 6.0 and later systems (Hybrid/PBX mode), when a system is
configured in a private network, various calls placed on one switch to another
switch may not complete correctly.
NOTE:
If your private network consists of more than two systems, a system
manager in the private network should be appointed to maintain system
forms for all systems in the private network. Any local modifications
should be cleared with this coordinating system manager, who must
ensure that changes to a local system do not have undesirable effects on
the private network as a whole. When modifications are made, he or she
should see that corresponding changes are made, as necessary, at
private networked systems. If your private network consists of two
systems, the managers should work together to assess and agree upon
any changes.
Troubleshooting Guidelines and Preparation
Before troubleshooting problems, obtain copies of your system's planning
forms. Many of the solutions offered in this chapter require that you contact the
coordinating system manager in your private network, who maintains records of
how systems in your private network are programmed and keeps them up to
date. Problems can occur when changes are made in a private network without
considering the needs of the private network as a whole. In particular, changes
to local and non-local dial plans, Uniform Dial Plan (UDP) routes, Automatic
Route Selection (ARS) routes, and remote access settings can have
unintended effects on other systems in your private network.
To solve a problem, you may need to perform system programming using your
MLX-20L programming console or PC equipped with System Programming and
Maintenance (SPM) software.
Most of the problems outlined here can be solved by system managers working
together in a two system private network or with the coordinating system
manager in a larger private network. However, some problems require the
