Network Call Transmission Level (Volume) Too Low or Too High
Network Call Transmission Level
(Volume) Too Low or Too High
When transmission levels are too high or too low, the coordinating system
manager must investigate the cause.
Possible Cause 1: Switch identifiers programmed incorrectly.
What to Do: Refer to the table below as you examine the problem. It lists the
rules for programming switch identifiers. At each system in a network, each
tandem trunk is programmed (individually or as part of a block of trunks) to
indicate the type of system connected to the other end of the trunk as well as
the distance between the connected systems.
1–20 = trunk connected to a MERLIN LEGEND Communications
System that is more than 200 miles away
21–40 = trunk connected to a MERLIN LEGEND Communications
System that is within 200 miles
41–50 = trunk connected to a system that is not a MERLIN
LEGEND Communications System (for example, a DEFINITY
ECS communications system) and is more than 200 miles away
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.
