2 T1 to Ethernet P2P to T1's - Adtran 908E gen 2

[rbidlack]

I have a customer who needs to set up a p2p Adtran 908E with 2 T1's on each side. 2 T1's - Ethernet - Ethernet - 2 T1's. Basically wants to use them as media converters. I was thinking of setting them up as sip gateways pointed at each other but they can't make the T1's PRI's. Maybe I am over complicating things but here is the config of what I have. This needs to traverse over the eth 0/2 interface, which is able to ping across to each other. I assume I need some type of trunk between the two but I'm not sure how to set that up.

I have a similar issue to yours and was hoping that someone would offer you some help. Have you figured it out yet?

Are you using Ethernet between the TA908s to extend T1s to external locations, or using T1s between the TA908s to extend Ethernet to external locations? Is this for data or for voice?

It would help if you could be more specific as to the problem that you're trying to solve. It sounds like either bridging or a pseudowire type of setup is what you're trying to achieve.

Some older TA900 firmware supported bridge groups but that was removed a long time ago. If we knew the exact use case or what you are trying to accomplish it would help.

Using Ethernet between adtrans to extend voice t1

Sorry for the late reply but in case this is still needed for someone else I'll update. 

I actually ended up using Engage IPTube devices that convert a T1 to ethernet since the Adtrans wouldn't pass through the DS0 signaling.
