Have a 3620 RAS router w/ PRI/digital modems connected to T1 that I can't seem to connect to any faster then 24k bps it also has a problem dropping connections.
Any input is greatly appreciated
Here's a look at the running config.

It wont take much to bring the modems (I am assuming they are MICA) to good looking connect speeds.
Since you are running some flavour of IOS rel 11.3 which is pretty old so I am assuming your modem code is not uptodate either. Therefore, please upgrade your MICAs to portware 2.7.3.0 as well as IOS to some latest 12.1 or 12.2 and see the difference.
