DCE to DTE connection will work just fine.

You can connect the two together but you will need to make sure one supplies clocking, and I am not sure on the media type but if you use RJ-45 make sure the pairs are flipped at the distant end.

For instance:

Router A

1-2-4-5

|- |- |- |

4-5-1-2

Router B

This is known as a T1 crossover

Yes, you can connect back to back using

Smart Serial DTE Interface To Smart Serial DCE Interface Crossover Cable.

Normally this is done for studying purpose.

I did purchase some of them last year from http://www.anthonypanda.com/?sp=&p=6&cat2=0&cat1=0&cat0=2&id=22&cat1=0&cat0=2&new=&more=&s=46b15dcbbdd425421eb3389650329c54〈=en
