I'm new to the adtran atlas 550. I'm using it for now 2 months. I'm trying to do a network with 3 cisco router 2811. It is a frame relay network using T1 card. The main problem is the Quat T1/pri module.The status goes from online to error 1 sec every 30 sec. The network isn't working. I've done all the maping, set the clock internal, enterred my DLCIs. There's no alarm. The adtran is sending package to the router but this one does not respond. On the router, all my network is set. here's an exemple of my 2811 config.

The real question is : Where's the problem? Im working on this for 2 weeks now. Any solutions why my card give me an error each 30 sec?
It sounds like the ATLAS T1 interface has clock slips. You can verify this by going to MODULES in the ATLAS menu, and then going to the MENU for the T1 module with the ERROR indications, and then going to PERFORMANCE CURR. Under the PERFORMANCE, if the CSS (controlled slip seconds) is incrementing then the ATLAS is taking clock slips on that T1 interface.
In your Cisco configuration I don't see a clock-source setting, but I don't remember what the default is for the Cisco. If the ATLAS' Primary Timing Source is set to INTERNAL, then make sure the Ciscos take timing from the T1s coming from the ATLAS.
Hope this helps,
Patrick

After verifying, it's a clock slip. All I have to do is identify where comes the other clock. I use the one on the line from the ADTRAN. On the cisco router, i had to set the clock source line on the controller T1.
I still have the problem, but now the Quad T1 card doesn't go online/error. Can you help me about the clock slip or I should ask the question on cisco community?
I'm not sure what the problem is now? You said the errors stopped on the ATLAS. Is the Cisco showing errors now? If it is, then I'm afraid you will need to go to the Cisco community for assistance with that.
If there is another issue, then I'll need more information about what that issue is.
We do have a guide for configuring an ATLAS for the Cisco Academy (https://supportforums.adtran.com/docs/DOC-1259). The Frame Relay configuration starts on page 5.
There is also a document for configuring Frame Relay to the internal router of the ATLAS (https://supportforums.adtran.com/docs/DOC-1298).
You do have encapsulation frame-relay IETF on the Cisco, which is needed to work with the ATLAS' Frame Relay.
Are the T1's in the ATLAS configured for all 24 DS0s? Is the Frame Relay UP? Are the DLCIs Active?
