E1 over ATM

We have a VWIC2-2MFT-T1/E1 card on the router 3845. Want to configure E1 over ATM, but not able to get the ATM interface. I am not able to find any command like " mode atm..." or " channel-group 0 unframed" Any idea how to configure on the contoller E1?

Re: E1 over ATM

Hi,

I suppose you mean ATM over E1?

A VWIC2-2MFT-T1/E1  card by itself doesn't support ATM. You need a card like AIM-ATM or something similar to enable ATM on these E1 cards. Here's a link to the documentation for this card

http://www.cisco.com/en/US/products/hw/routers/ps259/products_data_sheet09186a0080088753.html#wp39561

Once you have the necessary hardware, here's the  configuration you would need

network-clock-participate wic 0

network-clock-participate aim 0

network-clock-select 1 T1 0/0/0

network-clock-select 2 T1 0/0/1

!

controller T1 0/0/0

mode atm aim 0

framing esf

linecode b8zs

!

controller T1 0/0/1

mode atm aim 0

framing esf

linecode b8zs

!

Once this is done, you should see the ATM interfaces. Feel free to substitute E1 standards for T1 mentioned here and change the slot numbers as necessary.

Hope this helps
