Statistic Definition
LOG NUMBER 64
DESCRIPTION This log indicates that the unit attempted a PSTN connection to its
peer unit at too slow a bit rate. This severely damages system
performance since all bandwidth calculations are incorrect.
SEVERITY MAJOR
TASK TP
PRODUCT RLC, 9150
CANCELLATION None
ACTION TO BE TAKEN The PSTN path between a 9150 and RLC requires a clear 64K
channel.
If this log occurs every time a PSTN call is made, then either the
wrong service has been ordered from the telephone company or the
telephone company has provided the wrong service.
If this log occurs intermittently then the connection through the central
office has encountered some sort of problem.
It is still possible, however, that the wrong service has been ordered,
or provided, and that the majority of the time the PSTN has had a
clear channel by chance. Some customers have reported that they
requested the 64K channel, but a 54K channel was provided instead.
Another possible scenario is that bit errors could be occurring,
preventing communication from initializing at 64K, but allowing 56K.
This is probably the lease frequent cause.
PARAMETERS None
