asterisk users - Oct 2007 - Need T1 crossover cable?

I'm connecting a T1 PCI card to a Nortel Option 61 switch T1 card.  My
Sangoma A102D shipped with 2 T1 cables - which I assume are straight
through.  Do I need to make crossover cables for this scenario?
 
Thanks

Yes - a crossover *is* needed in this configuration.

Yes, use a T1 crossover(not an ethernet crossover).

As people answered here you need a crossed cable; Note that T1/E1 cables are
different than Ethernet.

T1/E1 uses pins 1,2,4,5 (while Ethernet uses 1,2,3,6). A crossed T1 cable is:

1  ----  4
2  ----  5
4  ----  1
5  ----  2
