9. Diagnostic using the internal Trace
For more sophisticated debugging an internal trace functionality is implemented.
This logging mechanism allows writing of ISDN and serial interface activities into
a wrap around buffer. The type of entries can be selected by a trace mask.
trcmsk – set tracemask
trcmsk par Setup the mask to select the type of data to be written
into the tracebuffer.
Default: D channel Layer 1 and 3, DTE interfacelines,
DTE-Data in connection-setup and clearing-phase.
The parameter par has to be setup in the following way,
all bytes have to be entered (default 00 00 00 00 00 00 00 80):
par := bl1 bl2 bl3 dl1 dl2 dl3 sl1 app
bl1 reserved 00
bl2 B channel frames (layer 2) disabled 00 (default)
enable HDLC frames 03
bl3 B channel packets (layer 3) disabled 00 (default)
enable X.25 packets 03
dl1 D channel layer 1 status disabled 00 (default)
enable C/I codes and states 77
dl2 D channel LAPD frames disabled 00 (default)
enable HDLC frames 03
dl3 D channel layer 3 messages disabled 00 (default)
enable layer 3 messages 72
sl1 serial line trace disabled 00 (default)
enable serial trace 05
app No call logging 00
enable call logging 80 (default)
