Definition
Destination address was incomplete or presented in an
unrecognizable format, which prevented the connection
from being established.
The network cannot provide the facility requested by the
user.
The equipment returns this message when it receives a
STATUS INQUIRY message.
A normal event has occurred with no standard cause
applying. No resulting action is required.
The call cannot be taken because no appropriate
channel is available to establish the connection.
A network problem prevented the call from reaching its
destination. Attempts to reconnect will probably fail until
the network problem is corrected.
A network error occurred. The problem will be resolved
shortly. Attempts to reconnect may succeed.
The destination cannot be reached because the
network switching equipment is temporarily overloaded.
The requested access information cannot be provided
by the network. The diagnostic message may explain
the problem.
The remote equipment cannot provide the requested
channel. This may be temporary.
An unknown problem prevents the remote equipment
from providing the requested resource.
The network cannot provide the requested quality of
service (as defined by CCITT recommendation X.213).
This may be a subscription problem.
The remote equipment is capable of providing the
requested supplementary service, but is not subscribed
to it.
The caller has requested a bearer capability that the
network can provide, but the user is not authorized to
use. This may be a subscription problem.
The network normally provides the requested bearer
capability, but cannot provide it now. This may be a
temporary network problem or a subscription problem.
An unspecified problem prevents the network or remote
equipment from providing the requested service or
option. This might be a subscription problem.
