Error on DISA BCM 400

[firefoxfire]

Trying to set up DISA on a PRI on a BCM 400 and when I enter the PUBLIC DISA DN and PUBLIC AUTO DISA DN is keeps saying "3319 not a valid option for Public DISA DN" I have read the docs for setting up DISA on a DID number on a PRI but I still can not get it to work.

Does anyone have the step by step instructions? Thank you

The problem was that I had TARGET LINE 260 with RCVD DIGITS 3319 and I tried to assign the DISA DN and that is the onflict. It can only be one or there other. So I deleted 260's RCVD DIGITS and it took it ok for the DISA DN and I got stutter dial tone and everything works ok now.
