Cause Definition
An invalid message was received, and no
standard cause applies. This is usually due to a
D-channel error. If this error occurs
systematically, report it to your ISDN service
provider.
The receiving equipment received a message
that did not include one of the mandatory
information elements. This is usually due to a
D-channel error. If this error occurs
systematically, report it to your ISDN service
provider.
The receiving equipment received an
unrecognized message, either because the
message type was invalid or because the
message type was valid but not supported.
Cause 97 is due to either a problem with the
remote configuration or a problem with the local
D channel.
The remote equipment received an invalid
message, and no standard cause applies. Cause
98 is usually due to a D-channel error. If this error
occurs systematically, report it to your ISDN
service provider.
The remote equipment received a message that
includes information elements which were not
recognized. This is usually due to a D-channel
error. If this error occurs systematically, report it
to your ISDN service provider.
The remote equipment received a message that
includes invalid information in the information
element. This is usually due to a D-channel error.
The remote equipment received an unexpected
message that does not correspond to the current
state of the connection. This is usually due to a
D-channel error.
A timer expiry initiated an error-handling
(recovery) procedure. This problem is typically
temporary.
An unspecified D-channel error when no other
standard cause applies.
