Pri/Bri Call Monitoring - Toshiba STRATA DK14 Installation And Maintenance Manual

PRI/BRI Call Monitoring

The DK ISDN circuit cards provide an RS-232 monitor function that enables you to monitor the
ISDN D-channel call progress layer two and three messages (setup, connect, and release). This
data can be monitored live, saved to a file, and/or printed using a PC with communication
software.
The hardware connections and communication parameters for the ISDN monitor port are shown in
Figure 16-33. Once this connection is setup and established, call monitoring data continues to be
sent (on the fly) as PRI and BRI calls are originated or received.
Two sample printouts from the RPTU monitor are provided.
start-up and synchronization sequences that occur at connection and power on.
shows typical ISDN PRI outgoing call setup and release sequences. BRI monitor data is similar to
PRI monitor data.
The communication parameters for all call-monitor jacks are 9600 bps, 7, 1, even.

monitor jack. The pin numbering and communication parameters are the same for each
call-monitor jack. The call-monitor jack on each PCB provides data only for the circuits of
the PCB on which it appears.
