ISDN event cause codes

These codes appear as associated (secondary) parameters in some
of the ISDN events.
Cause No. 1: unallocated (unassigned number). This cause
indicates that the destination requested by the calling user cannot
be reached because, although the number is in a valid format, it is
not currently assigned (allocated).
Cause No. 2: no route to specified transit network. This cause
indicates that the equipment sending this cause has received a
request to route the call through a particular transit network which it
does not recognize. The equipment sending this cause does not
recognize the transit network either because the transit network
does not exist or because that particular network, while it does
exist, does not serve the equipment that is sending this cause.
This cause is supported on a network-dependent basis.
Cause No. 3: no route to destination. This cause indicates that
the called user cannot be reached because the network through
which the call has been routed does not serve the destination
desired.
