Cause No. 81: invalid call reference value. The equipment
sending this cause has received a message with a call reference
which is not currently in use on the user-network inter face.
Cause No. 82: identified channel does not exist. The equipment
sending this cause has received a request to use a channel not
activated on the inter face for a call. For example, this cause is
generated if a user has subscribed to the channels numbered from
1 to 12 on a primar y rate inter face and the user equipment or the
network attempts to use channels 13 through 23.
Cause No. 83: a suspended call exists, but this call identity does
not. A call resume has been attempted with a call identity which
differs from that in use for any presently suspended call(s).
Cause No. 84: call identity in use. The network has received a
call-suspend request. The call-suspend request contained a call
identity (including the null call identity) which is already in use for a
suspended call within the domain of inter faces over which the call
might be resumed.
Cause No. 85: no call suspended. The network has received a call
resume request with a call identity information element which
presently does not indicate any suspended call within the domain
inter faces over which calls may be resumed.
Cause No. 86: call having the requested call identity has been
cleared. The network has received a call resume request with a call
identity information element which once indicated a suspended call,
however, that suspended call was cleared while suspended (either
by a network time-out or by a remote user).
Cause No. 88: incompatible destination. The equipment sending
this cause has received a request to establish a call that has a
low-layer compatibility, high-layer compatibility, or other compatibility
attribute (for example, data rate) which cannot be accommodated.
Cause No. 91: invalid transit network selection. A transit network
identification was received which is of an incorrect format as
defined in Annex C/Q.931.
Cause No. 95: invalid message, unspecified. This cause is used
to repor t an invalid message event only when no other cause in the
invalid-message class applies.
