Question about Ground Start - Loop Start

[baze7]

I have an access advantage T1 for now. It runs in to a adtran TA850 channel bank, then analog into my norstar. I have been getting phantom rings, disconnects, and static for quite some time now. I have talked to AT&T they said the T1 is testing fine. My question is what can I look for. In the access advantage the FXS lines are set for loop start, the T1 is AMI per AT&T. Can someone tell me what else I can look at?

Thanks

bare7, did you get it resolved?

Also, per the title of your post- Norstars won't take ground start lines- gotta be loop. If you're concerned that your adtran may be giving you ground start, rest assured they're not. You wouldn't be able to call out.
