Correct
you are looking for a DS1-X cable. If I recall, T1 cables are RJ48c spec, so
in a crossover scenario pin1 goes to pin4 and pin 2 goes to pin5 and vice versa.
If you had the wrong cable, the carrier wouldn't even come up, let alone the B
or D channels.

Maybe I misunderstand, but what you're saying doesn't seem right. I've never
connected Asterisk to Asterisk but I've connected Asterisk line side to a bunch
of different things (Avaya and Nortel PBXs). I've alway used a T1 crossover
cable and then had one side act as NET and the other as CPE.
My understanding was that the crossover cable addressed the electrical
requirements and the CPE/NET settings addressed signalling requirements. Am I
wrong?
I would expect that if Dave had the wrong cable, he wouldn't get anything at
all in terms of call setup. In fact, I would think the B and D channels
wouldn't initialise.
