The ATLAS needs to have the T1/PRI port configured for PRI under the DIAL PLAN.
You can look at this Cisco Academy Guide for details. The guide is for the ATLAS 550, but all the ATLAS products have the same configuration for the DIAL PLAN.
It looks like your PRI switch type is going to be "AT&T 4ESS.
Hope this helps,
By typing AT&T 4ess you are referring to the Adtran side, right?
There is no AT&T 4ESS on Cisco router under the isdn switch-type:
PSTN_WKF_2(config)#isdn switch-type ?
primary-4ess Lucent 4ESS switch type for the U.S.
primary-5ess Lucent 5ESS switch type for the U.S.
primary-dms100 Northern Telecom DMS-100 switch type for the U.S.
primary-dpnss DPNSS switch type for Europe
primary-net5 NET5 switch type for UK, Europe, Asia and Australia
primary-ni National ISDN Switch type for the U.S.
primary-ntt NTT switch type for Japan
primary-qsig QSIG switch type
Yes, I was referring to the ADTRAN ATLAS configuration, since your Cisco is set up "primary-4ess". The ATLAS switch types are:
Lucent 5E Lucent 5Ess switch type
Northern DMS100 Nothern Telecom DMS-100 (sometimes called NI-1)
National ISDN National ISDN (also known as NI-2)
AT&T 4ESS AT&T 4ESS switch type
If you have any compatibility issues, it is more common to run the NATIONAL switch type.
