3600 + ATM T1 IMA module =

[polm]

I have a 3600 series router with a NM-4T1-IMA module.

Can I use this to connect to a standard T1 link and provide routing across that link just like I would with a 2600 + WIC-1DSU-T1 ?

yes.

Its nothing more than a 4-8 port T1 card with a SAR chip.

that's what I was hoping ! thanks spidey.

segmentation and re-assembly. The hardware required to take a frame and chop it up into cells with appropriate addressing/signaling.

Reference my participation on the ATM vs. Ethernet forums in 1999. Not the internet kind, the kind where you get a bunch of geeks in a room and we geek fight and our findings are published.

I would double and triple check that... Since it includes a SAR chip, its going to encapsulate anything on the T-1 in ATM. If you only use a single T-1, thats fine. However, the other end of that T-1 must also be expecting ATM because its not going to be clear channel HDLC. Its actually a 4/8 port T-1 card hardwired for ATM... Its no different than a single DS3 card hardwired for ATM.

I agree, double check (ie, call cisco)

It was my understanding that you can use it just like a normal T1 card, but with the added benefit of hardware IMA. I've used them before in normal T1 applications but it has been quite a while.
