[cisco-voip] T1 xover or straight through?

[Go0se]

As a general rule a T1 crossover cable is always required between PBXs no
matter how you interconnect them. I'm not aware of a T1 controller that will
auto-mdix. You can build your own T1 crossover - cross pins 1&2 to pins 4&5.
(1 to 4 and 2 to 5)

Anyone know if you need a straight through or t1 crossover to go from
an IAD to a 3845 with a PRI port?  We have some IAD's that terminate
with CMM's and those use t1 crossovers.  Not sure about the 3845
ports.

Connecting to AT&T circuits to the 3845's required straight through.
Wish I had one to test.

Just wondering if anyone might know, wondering if the 3845s can handle
either / or, and if the requirement comes from the demarc side (either
AT&T or IAD's).
