Error Description

3894 Protocol detail; may offer a
clue if customer is having

3902 FRANCE ONLY: Service
not authorized.

available, unspecified.

report a service or option
not available event only
when no other cause in the
service or option not

ISDN-SGR (ISDN-PRI Signaling Group)
Recommendation
This could be a local administration problem only, or a
mismatch between the local administration and that of
the network provider.
From the media module and port number (in the Aux
Data field), determine the trunk group against which
the error was reported.
Display the trunk group form: If the trunk group is
Call-by-Call (Service Type is "cbc"), check all routing
pattern forms 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.
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 GGGVSpp 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.
