Private Network Call Transmission Level (Volume) Too Low or Too High
programmed on the switches on the other end of the tandem
trunk. Systems B and C are linked by trunks whose identifiers
indicate distant systems.
System A
NY, NY
The example below shows programming that would be incorrect
in the same private network. The link between Systems A and B
has mismatched identifiers, because System B specifies that
System A is more than 200 miles away. System C incorrectly
specifies System B as a non-MERLIN LEGEND Communications
System.
System A

4. If any of the programming is incorrect, one or more system
managers must correct it. The coordinating system manager
must clear any changes. To change the switch identifiers at your
local system, see "Switch Identifiers" on page 5–13 or "UDP
Facilities" in Chapter 3 of System Programming . If the
programming appears to be correct, skip to Step 6.
5. Make some test calls across the private network. If calls are at the
proper levels, the problem is solved. If transmission levels are still
incorrect, proceed to Step 6.
6. If the identifiers appear correct but the distance between systems
is between 180 and 220 miles, you may need to experiment with
switch identifiers in order to achieve the correct transmission
levels. Return to Step 4.
If changing one or more switch identifiers do not solve the problem,
Possible Cause 2: More than three analog spans are involved in the call.
What to Do: This may occur when calls are transferred or forwarded multiple
times across analog facilities. Consider changing to digital facilities if this
