Network Call Trace

Network Call Trace (NCT) is available to trace a network call and to
diagnose network problems. When a network call is blocked, trace data
is output indicating the reason the call was blocked and the software
procedure responsible.
A network call can be traced by dialing a Special Prefix (SPRE) code and
the NCT feature code (9912) before the network number. When this is
done, call setup and status information is output to the system terminal as
the call tandems through the network. The trace information is output to
all the system terminals designated in LD 17 as ADAN = TTY and USER
= MTC.
