UC520 ISDN issues

Unanswered Question
Jan 14th, 2010

Hi Everyone,

I have a customer with a UC 520 telephone sytem. The equipment has been setup with 2 ISDN ports. At this stage only one is been used, but everytime I do work on this, it actives the second ISDN port. The first call pick up 0/1/0 port. When you make a second call out it picks up 0/1/1 port. 0/1/1 is not been used. In the programming how can I turn off 0/1/1 totally. look forward on your email back. thank you

regards

Chris Kane

I have this problem too.

Hi Chris,

You can Administratively shut it down :)

Type the following commands in

Router# conf t

**It will now go into configuration mode**

Router(config)#

**Type the following**

Router(config)#interface BRI0/1/1

**It will now be in Interface Configuration mode**
Router(config-if)#

**Type the following**

Router(config-if)#shut

This will put that interface in Administratively shutdown mode, it should not reactivate itself until you do it by running the "no shut" command on that interface.

Of course the above assumes you know your way around the CLI (At least basic understanding).

Hope this helps and it solves your problem for you.

Cheers,

David.
