Reference Guide for the Model RT328 and Model RH348 ISDN Routers
D-2 Using the Protocol Analyzer and Trace Tools
ISDN Protocol Analyzer
An ISDN call connection failure can be diagnosed using the ISDN embedded protocol analyzer
(EPA) of the Model RT328/RH348 router. The EPA executes from the command line interface
within the internal Manager. You must first connect to the router using the serial Manager port.
The EPA will not operate by Telnet.
To invoke the EPA:
1.
Access the internal Manager using a serial terminal connection.
2.
If you will be tracing an outgoing call, go to Menu 11 (Remote Node Setup) and note
which remote node number, N
, corresponds to the location you will be calling.
3.
Invoke the Command Interpreter Mode (Menu 24.8).
4.
Turn on the screen capture/log capability:
rt328> isdn ana on
5.
Trace the call.
To trace an outgoing call, force the router to dial the remote node by entering:
rt328> isdn dial N
(
N
is the remote node number shown in Menu 11.)
Or, to trace an incoming call, enable incoming trace by entering:
rt328> sys event
6.
Wait for all progress messages, and then (if necessary) force the router to drop the ISDN
connection by entering:
rt328> isdn drop all
7.
Display the analyzer trace by entering:
rt328> isdn ana disp
The trace appears on the screen as in Figure D-1. Use PageUp and PageDown to inspect the entire
trace.
Figure D-1 shows the ISDN Protocol Analyzer Display.
