Callback Does Not Work
Callback Does Not Work
Callback allows queueing for an available line/trunk connected to the local
system. If a user attempts an ARS- or UDP-routed call and hears a busy signal
or warble tone, the signal may be derived from a non-local system’s tandem or
PSTN facilities. If this is the case, Callback does not work. When all available
routes on the local system are busy, a caller can use Callback to wait for an
available facility in the Route 1 pool.
Private 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 private 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
