Cisco 3845 - AIM-ATM-4T1 - Image?

Note, these images are basicly two trains with minor bug fixes between them. You have 12.4(x)T and 12.4(x), with the SP Services feature license. Not a whole lotta difference between them altogether.

The Cisco Product guide says the ATIM-ATM-4T1 is supported on the 3800 series from 12.3(11)T onwards in the SP Services feature set.

So, you should be safe with any of these.

I'd try 12.4(16b) first off, although if you need the features in the T train for other things, then 12.4(15)T1 would be the next one. You shouldn't need T for just the AIM-ATM-4T1, but other features you configure may need it.

Thanks for the quick response. Can you give me some idea what the T train does exactly? We have a 3662 with a first generation IMA card installed that was communicating with an identical 3662. One of the

3662's has died and we replaced it with the 3845 and the AIM-ATM-4T1. I know it's a heavy request, but do you happen to know if your images will support the trunking of the T1's for data to the older 3660?

Thanks!

The T train is the Technology train. This is where Cisco develops new features and beta tests them on users. Most new features you get are going to be in the T train first, and then IOS next-gen takes the previous T train and makes it the mainline. So eventually 12.5 will be what 12.4T has in it.

IMA binding of T1 traffic should be a pretty basic application for the AIM-ATM, I'd imagine any IOS image that supports the AIM-ATM supports IMA binding the T1s. Afterall, the 3662 is two gens back, and was doing it for you.. I personally haven't done it with this hardware combo, but Cisco Feature Navigator (cisco.com/go/fn) says Inverse Multiplexing over ATM (IMA) is supported on the 3845 for 12.4 SP Services. (with no subversion selected).
