Quick question: If I have two E1 ports (RJ45), then will running a straight ethernet cable between the two ports have the same affect as plugging a ballan into each port and using a pair of coax (over a v. short distance).

Likewise would using an ethernet crossover cable have the same affect as swapping the pairs round on one balland.

Or are the pinouts different to ethernet? I tried googling but couldn't find anything (perhaps because I can't seem to spell ballan :/ ).

The pinouts are different. It's easy to make your own E1 crosscable though.

E1 uses pairs 4-5 and 3-6, just swap those.

4-5 <------------> 3-6 3-6 <------------> 4-5

I wrote this from memory, and I got it wrong. Sorry. It's not 4/5 and 3/6, but 1/2 and 4/5 (as others undoubtedly will point out). Mike.
