Table17-10 ISDN Cause Values (continued)
Hex Value
Cause
Explanation
95
Call rejected
The destination is capable of accepting the
call, but it rejected the call for an unknown
reason.
9C
Invalid number format
The connection could not be established
because the destination address was
presented in an unrecognizable format or
because the destination address was
incomplete.
9F
Normal, unspecified
This reports the occurrence of a normal event
when no standard cause applies. No action is
required.
A2
No circuit/channel
available
The connection cannot be established
because no appropriate channel is available
to take the call.
A6
Network out of order
The destination cannot be reached because
the network is not functioning correctly, and
the condition might last for an extended
period of time. An immediate reconnect
attempt will probably be unsuccessful.
AC
Requested
circuit/channel not
available
The remote equipment cannot provide the
requested channel for an unknown reason.
This might be a temporary problem.
B2
Requested facility not
subscribed
The remote equipment supports the
requested supplementary service by
subscription only. This is frequently a
reference to long-distance service.
continues
B9
Bearer capability not
authorized
The user requested a bearer capability that
the network provides, but the user is not
authorized to use it. This might be a
subscription problem.
D8
Incompatible destination
This indicates that an attempt was made to
connect to non-ISDN equipment—for
example, to an analog line.
E0
Mandatory information
element missing
The receiving equipment received a message
that did not include one of the mandatory
information elements. This is usually the
result of a D-channel error. If this error
occurs systematically, report it to your ISDN
service provider.
E4
Invalid information
element contents
The remote equipment received a message
that includes invalid information in the
information element. This is usually the
result of a D-channel error.
