8.17 Trace Mask Configuration Request
Set the ISUP module's event masks for tracing (input and output) messages
to the trace module on a per-primitive basis and tracing non-primitive events
on a per-event basis. The Trace Mask Configuration Request message can be
used to enable and disable the tracing of some or all of the messages
supported by the ISUP module. This message may be sent at any time even
before the initial per-module configuration message has been sent to the
ISUP module. The fields in the masks are defined below:

Parameters
op_evt_mask
The output event trace mask. This is a 32-bit value with bits set to 1 to
cause a trace message to be sent to the system trace module whenever a
message is issued by ISUP for the events indicated:
