Introduction

Ideally, setting up an ISDN connection is very much a straightforward process:

z Connect the router to the ISDN network interface.

z Configure ISDN call definitions on the router. See How To Configure ISDN Calls On Allied

Telesis Routers, available from www.alliedtelesis.com/resources/literature/howto.aspx.

z Send traffic.

However, for one reason or another, there are occasions when the setup process is not as

smooth as it should be.

So if you have set up your router to communicate over ISDN, but the setup does not appear

to be working, this How To Note contains some steps you can take to try and resolve the

problem.

Which products does it apply to?

This configuration applies to the following Allied Telesis routers and switches, when a BRI or

PRI interface is installed in the base unit or through a PIC:

z AR300 series routers

z AR400 series routers

z AR700 series routers
