Cisco 2600 multilink config help

Hello folks, I have a Cisco 2600 with 2 Multilinked T1s from ATT. Am having some output issues on it. Input is fine (3Mb), but output has never exceeded like 512kb. Also, I am getting a lot of input/CRC/Frame errors on the Ethernet port. It is connected to a 24 port switch.

I really need some help on this, I think I have some type of configuration error.

Any suggestions? I don't know a whole lot about this.

Thanks.

First, let me be clear - I know NADA about this.

However, this site seems to be talking about that setup pretty clearly; http://www.tek-tips.com/viewthread.c...1225832&page=1
