So I've worked one of Cisco's newer cards the NM-1T3/E3 This card is supported on the 2650XM and up. The processor on the 2600 series routers will only support subrate T3 tho. This means that you must set the dsu bandwidth below 25000 or so. If you try and do full rate you will get input and output errors on the interface but no errors on the controller. Which I feel is a weird response.
I found that there is not much documentation around for this card. to set it up you fisrt need to use the card type command. the syntax is card type *T3 or E3* *module number*. You will then have a controller interface and a serial interface to work with. From there is a pretty standard setup.
If you need a T3 on a lowend platform this is the card for you.
