What kind of T1 service to use with a T1 IMA card?

[admin_2]

If I have two routers geographically separated, and each router has a 4 port T1 IMA ATM module, what kind of T1 service do I need to order?

Let's say I want 3Mbps bandwidth. So, I have to order 2 access T1's at each location. Now, do these T1's have to be leased lines? Can they be frame-relay? Can I connect the IMA card to a provider's ATM network??

Also, will a multiport IMA ATM card support just one T1, or does it have to be at least two??

The IMA cards are specifically for

ATM network connectivity;

You can use any number of the 4 ports

that you wish.
