3640 Line Modules Needed For my Setup - Advice?

[starsky]

All-

I've got a pretty basic question. I've been running a 3640 Cisco with 4 T1 CSU/DSU modules for a number of years.

We are now going to "up" our bandwidth and our provider is going to give us a single Ethernet handoff. So basically I can just "throw away" the T1 modules and I need an Ethernet modules.

What specifically do I need?

I've been checking out the line card list on Cisco's site:

http://www.cisco.com/en/US/products/hw/routers/ps274/prod_models_comparison.html

As far as my router is concerned, it will just think it's on a lan because our provider is just setting us up with an Ethernet handoff (at least that's my guess)

I'd like 10/100 - FastEthernet capability - we can burst up to 100 megs.

I'm assuming: NM-2FE2W or NM-1FE2W or NM-1FE-FX

Does that sound right?

Thanks in advance,

Hutch
