Private Network Call Transmission Level (Volume) Too Low or Too High
51–60 = trunk connected to a system that is not a MERLIN
LEGEND Communications System (for example, a DEFINITY
ProLogix Solutions communications system) and is within 200
miles
NOTE:
DEFINITY ECS and DEFINITY ProLogix Solutions systems are beyond the
scope of this guide. For information about how these systems identify
tandem facilities, see the documentation for the applicable system.
Follow the steps below to check on the problem.
1. Check the routing for the call, and identify each system where the
call is routed, including the system where the call originated or
was received from the public switched telephone network. See
"Reviewing the Non-Local Dial Plan and Routing" in Chapter 6 of
Network Reference for instructions.
2. As necessary, note the switch identifier programmed on each
system for the trunks that carry the calls. To review a report
including the switch identifiers programmed on a system, select
the
choose
3. Look for switch identifiers that incorrectly specify the distance
between systems or that specify the incorrect type of system. The
diagram below shows how switch identifiers might be
programmed at either end of tandem trunks in a hypothetical
private network. A switch identifier is programmed to identify the
system at the opposite end of the tandem trunk. In the example,
all three switches are MERLIN LEGEND Communications
Systems. On the facility that links Systems A and B, the system
managers program identifiers to indicate that they are within 200
miles of one another. Next to the name of each system, is the
switch identifier associated with that switch. The switch is
option on the System Programming menu and then
