27 Destination out of
order A signaling message cannot be delivered because
the interface is not functioning correctly, and the
destination cannot be reached. This condition
might be temporary; for example, remote
equipment might be turned off.
28 Invalid number
format Destination address was incomplete or presented
in an unrecognizable format, which prevented the
connection from being established.
29 Facility rejected The network cannot provide the facility requested
by the user.
30 Response to
STATUS INQUIRY The equipment returns this message when it
receives a STATUS INQUIRY message.
31 Normal, unspecified A normal event has occurred with no standard
cause applying. No resulting action is required.
34 No circuit/channel
available The call cannot be taken because no appropriate
channel is available to establish the connection.
38 Network out of order A network problem prevented the call from
reaching its destination. Attempts to reconnect will
probably fail until the network problem is
corrected.
41 Temporary failure A network error occurred. The problem will be
resolved shortly. Attempts to reconnect may
succeed.
42 Switching
equipment
congestion The destination cannot be reached because the
network switching equipment is temporarily
overloaded.
43 Access information
discarded The requested access information cannot be
provided by the network. The diagnostic message
may explain the problem.
44 Requested
circuit/channel not
available The remote equipment cannot provide the
requested channel. This may be temporary.
47 Resource
unavailable,
unspecified An unknown problem prevents the remote
equipment from providing the requested resource.
49 Quality of service
unavailable The network cannot provide the requested quality
of service (as defined by CCITT recommendation
X.213). This may be a subscription problem.
50 Requested facility
not subscribed The remote equipment is capable of providing the
requested supplementary service, but is not
subscribed to it.
