System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the Primary Signaling Link Hardware Check, for
example, you may also clear errors generated from other tests in the testing
sequence.
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.
This error might be helpful as a clue if the customer
complains of receiving unexpected intercept tone after
accessing ISDN trunks or PRI endpoints. Determine the
trunk group from the circuit pack and port number (in the
aux data field) and then check the BCC fields of the
pertinent routing patterns. 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).
