Error
Code Description
3906 Protocol detail; may offer a
clue if customer is having
ISDN calls denied with an
unexpected intercept tone.
3909 A request to use a network
service has been made, but
the network has rejected
the request because the
requested service is not
implemented.
3928 A call was denied because
of a basic incompatibility
between the type of call and
either the facilities selected
by the routing pattern or the
called user itself.
System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. For example, by clearing error codes associated with the
Primary Signaling Link Hardware check (#636), you may also clear errors
generated from other tests in the testing sequence.

Recommendation
1. If customer is complaining of unexpected intercept
tones when accessing ISDN trunks or PRI endpoints
and no other cause can be found, escalate to the
problem and provide the next tier with this Error Log
information.
1. Follow the recommendations listed above for Error
Type 3890.
This error might be helpful as a clue if the customer
complains of receiving unexpected intercept tone after
accessing ISDN trunks or PRI endpoints.
1. Determine the trunk group from the circuit pack and
port number (in the aux data field)
2. check the BCC fields of the pertinent routing patterns.
3. Also, investigate whether or not the calling and called
endpoints are compatible (for example, some ISDN
switches may not allow a voice station to call a data
extension).
