Configuring Demand Routing for Primary ISDN Modules
Troubleshooting Demand Routing
To set up a test call, enter the following from the BRI interface configuration
mode context:
Syntax: test-call [dial <number> | answer | hangup]
To enter test call mode, enter:
ProCurve(config- bri 2/1)# test-call answer
This command configures the router to receive test calls.
To dial a test call, enter:
Syntax: test-call dial <number>
Replace <number> with the LDN of the ISDN interface you want to connect
to. Enter the LDN without using any special characters. For example, you
may enter:
ProCurve(config-bri 2/1)# test-call dial 15555551212
The router will then make a call. Once the test call is connected, the routers
will exchange keepalives every 10 seconds.
To disconnect the test call and free the allocated BRI channels, enter:
Syntax: test-call hangup [channels <channel range>]
Entering the hangup option disconnects the entire ISDN test call. You can
also hang up a single B channel by using the hangup channels option and
specifying on which channel or channels you want to terminate the connec-
tion. For example, if you want to hang up both B channels but leave the D
channel connected, enter:
ProCurve(config-bri 2/1)# test-call hangup channels 1,2
or
ProCurve(config-bri 2/1)# test-call hangup channels 1-2
To hang up a specific channel, enter the number of the B channel you want to
disconnect. For example, if you wanted to hang up channel B2, you would
enter:
ProCurve(config-bri 2/1)# test-call hangup channel 2
Test calls allow you to check the physical ISDN connection, end to end,
between the calling router and the receiving router.
