Re: OC-3 connectivity to branch site

First, you will need to determine the type of OC-3 being brought to you from your Telco provider and verify that you purchase the correct 3640 interface. The URL below will take you to the interface selection or you can go to the cisco product catalog for the 3600 router line.

OC-3 circuits are fiber optic, ATM circuits that provide a number configuration options for QOS and are ideal for both large amounts of data as well as voice/video applications. Just about anything you would ever want to know about ATM can be found

As far as the IOS version, I would select the appropriate version for the protocols I was intending to run as well as meeting the requriements for the network modules I was installing. I had good luck with 12.0(7)T on a 7204VXR for an OC3 with T1 CES routing IP only.

Interface configuration is pretty straightforward and there are numerous examples avaible at the TAC, but you can start here at the ATM configuration guide:
