If the interface is not activated, the reason could be one of the following:

The interface has been put into NT mode.

On the AT-AR041 and AT-AR042 multi-BRI NSM modules it is possible to put the ISDN

interface(s) into NT mode so that they can emulate a network switch interface. This can

be useful for bench testing network configurations. To see which mode the ISDN interface

is currently in, use the command:

show bri=n state

The first item in the output, Interface Type, will have either the value NT or the value TE.

If the ISDN interface is in TE mode then it is set up correctly.

If the ISDN interface is in NT mode it is set up incorrectly, and it is a matter of changing

a pair of jumpers on the circuit board to put the interface back into TE mode.

There is a physical fault in the router's ISDN interface circuitry.

The router is able to test its own interface. The steps to performing the self-test are:

Create a BRI loopback plug and insert it into the interface socket.

If the BRI interface under consideration is on an ICM card, it is not necessary to use a

loopback plug, as the interface is capable of internal loopback, and so does not need

external loopback.

At the command prompt, enter the command:

enable test int=brin

where n is the number of the BRI interface under consideration. Interfaces are

numbered from 0.

This initiates a 4-minute self-test.

Wait 4 minutes, until the router outputs a message to inform you that the self-test is

complete.

Then enter the command:

show test

which will output the test results as shown in the following figure.

ICM-BRI1

Result

no test

complete

good

If the Result column shows the result to be good, then the BRI interface has no physical

faults (that the self-test can detect, anyway). If the result is anything other than good,

then the interface is faulty and you need to contact your distributor regarding a repair.
