PRI/BRI Call Monitoring
The CT 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
. 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.
shows typical
ISDN PRI start-up and synchronisation 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, 8, 1, none.
Note
The RPTU and the RBSU ISDN interface PCBs each have a call-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.
