Is it ok to cross connect 2 CISCO 2600 routers with T1 cards?

I was given 2 identical Cisco 2600 routers, both have T1 cards in them. I would like to test the routers but don't have a T1 line available.
Is it ok to use a crossover cable between the 2 T1 cards in the 2 routers?

Yes, but you need a T1 crossover cable (versus an Ethernet crossover cable).

I know how to make a crossover cable for a T1.
Someone told me that you can't cross these cards due to a possiblity of power overdrive. His words.

Not sure what he meant.  Maybe the TX line is to hot for the RX line if they are a direct cross.

Yes, I've done it before. It should be fine.

I currently have 4 different 2600s ( 2 2612s and 2 2620s ) crossconnected to eachother at home in my test rack.  No problems at all.
