ISDN Switch Loopback Test
The ISDN loopback test is designed to confirm the existence of a working ISDN line and the proper configuration
of certain Netopia R310 ISDN Router parameters. This test is available only on switched ISDN lines.
Using the first B-channel, the test calls the Netopia R310 on the second B-channel, creating a call loop back to
the unit.
To run the ISDN loopback test, select ISDN Switch Loopback Test in the Utilities & Diagnostics screen and
press Return. The ISDN Switch Loopback Test screen appears.
Note: "Number to Dial Directory Number 1 and 2" fields are only visible if there are no DNs in the ISDN line
configuration.
Select Run Test Now and press Return. The loopback test is executed immediately.
Note: Make sure neither B-channel is in use before you execute the loopback test.
The Status item reports one of three results:
Untested: The loopback test has not yet been run.
Loopback Test FAILED: The loopback test has failed. See “If the loopback test fails,” below, for troubleshooting
suggestions.
Loopback Test PASSED. The loopback test was successful. The line is working properly, and the directory
numbers (the ISDN phone numbers associated with each B-channel) are correct.
