ATM Services on 3900 series routers

[nitsg.gupta]

Dear All,

I have existing 3745 router with "NM-4E1-IMA"   card and need the same card on 3845 & 3945 router. I have checked  card   replacement docs of this card and found "AIM-ATM-4T1/E1" card as   replacement for 3845 router.

I am not getting any document which provides card replacemnt info for 3945  series   router.

I need 2 or 4-port E1 ATM Network Module with IMA OR any module which   fulfills the need of this requirement on 3945 router.

Our WAN links are E1 links and configuration is done under ATM interface.

Any 1 or 2 E1 port module with ATM. Please suggest.

Thanks,

Nitin

Hello Nitin,

I'm afraid the only ATM interface supported are T3/E3 or OC3

see

http://www.cisco.com/en/US/prod/collateral/routers/ps10538/aag_c07_563807.pdf

modules AIM are listed under the unsupported list.

But the new routers have a different module already installed that might be used with the E1/T1 VWIC2

see also Q&A

Q. Will the integrated services routers generation 2 support traditional interface types such as Inverse Multiplexing over ATM (IMA)?

A. The new routers are designed to provide the interfaces and services in today's advanced networks and to keep up with network growth for many years to come. As part of that design philosophy, some traditional connection methods with very little market demand are not supported in favor of more modern connection types. IMA is one such technology, and it will continue to be available for some time on existing integrated services routers. A full list of supported modules is available at http://www.cisco.com/go/isr.

Hope to help

Thanks Giuseppe,

I already had this info and was looking for something which solves the issue. so this new ISR2 routers will not support ATM services with E1/T1 at all.

anyway thank you very much for your help.

regards,

Nitin
