Recommendation
This could be a local administration problem only, or a
mismatch between the local administration and that of the
network provider.
1. From the circuit pack and port number (in the Aux Data
field), determine the trunk group against which the error
was reported.
2. Display the trunk group form: If the trunk group is
Call-by-Call (Service Type is "cbc"), check every routing
pattern form containing this trunk group to see if the
Service/Feature fields contain the correct network
services purchased for this trunk. If the trunk group is
not Call-by-Call, check that the Service Type field
contains the single network service purchased for this
trunk.
3. If local administration appears correct, consult with the
customer and/or the network provider to determine the
services that the customer has subscribed to for this
trunk group.
If customer is complaining of unexpected intercept tones
when accessing ISDN trunks or PRI endpoints and no other
cause can be found, escalate the problem and provide the
next tier with this Error Log information.
First, eliminate any transitory state mismatch problems by
issuing the test port UUCSSpp command for the trunk port
shown in the aux data field. Test #256 (Service State Audit)
is the important test in the sequence. If this passes
satisfactorily, yet the customer continues to complain of
unexpected intercept tones when accessing ISDN trunks or
PRI endpoints and no other cause can be found, escalate
the problem and provide the next tier with this Error Log
information.
