Typical X.25 and ISDN Data Analyzer Sessions
4-Channel T1/E1 Multiplexer Sessions
Starting ACC and ISDN
Once a ttgenfile is properly configured per the preceding installation, the
ACC Mux subsystem can be started using the appropriate .tmem file:
$ zmasterd cold /opt/acc/cfg/isdn.tmem
Once ACC Mux is up and running, start the ISDN subsystem daemon:
$ /opt/acc/bin/isdnconfd -f /opt/acc/cfg/isdn/icheck/itest
Once the ISDN/ACC subsystem is up and running, start the pcapture
daemon:
$ /opt/acc/bin/pcapture
(The pcapture program can also be started automatically with the ACC
Mux Subsystem by adding the statement “start pcapture” to the file
/usr/zcomopt/acc/cfg/zmasterd_list. This will cause zm asterd to
automatically start this program.)
X.25 Connection
This sequence verifies that X.25 Virtual Circuits can be established over
ISDN B (Bearer) channels. For these sessions the x25server and x25check
routines were run on the same node to execute a loopback connection
test, but verification of Packet Level connection between a local source
node and a remote destination node is essentially the same.
Bring up the Level 2 connections using x25init on the configuration files.
For example:
# x25init -c /etc/x25/00looptest
Since the x25server utility awaits call requests from x25check,itis
scheduled first and followed by the x25check routine:
# x25server
# x25check 4082524346 -ilooplink -n 1 -s 10
Arguments used for the x25check runstring are the
programmatic_access_name (-i), the number_of_messages (-n), and the
size_of_messages (-s) in octets.
