successful.
Cause No. 39 – Permanent frame mode connection is out-of-service [Q.850 only]

immediately. May also indicate a data link layer malfunction locally or at the remote network
interface or that a call was cleared due to protocol error(s) at the remote network interface.
Cause No. 42 – Net busy, redial (Switching Equipment Congestion)
is cause indicates that the switching equipment generating this cause is experiencing a period
of high traffic.
Cause No. 43 – Access/user information discarded
is cause indicates that the network unable to deliver user information (i.e user-to-user
information, low level compatibility or sub-address, etc) to the remote users as requested.
Cause No. 44 – No channel available (Requested circuit/channel not available)
is cause is returned when the circuit or channel indicated by the requesting entity cannot be
provided by the other side of the interface.
Cause No. 46 – Precedence call blocked [Q.850 only]
is cause is used to indicate that there are no pre-emptable circuits or that the called user is
busy with a call of equal or higher pre-emptable level.
Cause No. 47 – Resource unavailable/New Destination
is cause is used to report a resource unavailable event only when no other cause in the
resource unavailable class applies.
or
is cause is used to indicate that the original destination is unavailable and to invoke redirec-
tion to a new destination.
Cause No. 49 – QOS unacceptable
is cause is returned when the Quality of Service is unacceptable.
CLASS 1.3 (service or option not available)
Cause No. 50 – Requested facility not subscribed
e cause is used to report that the user cannot use this feature because s/he has not subscribed

Cause No. 51 – Bearer capability incompatible with service request
is cause indicates a user request for action was rejected because the action was incompatible
with the capability of the call.
Cause No. 52 – Outgoing calls barred
is cause indicates that because of call screening provided by the network, the calling user is
not permitted to make a call.
