Re: connect two T1 card by cross cable?

Yes, you may. However, an Ethernet cross-over cable will not work.

You need a cable or device that will cross pins 1&2 with pins 4&5 (for T1).

Holding the end of the cable with the clip down/away from you, the pair to the left will be either orange or green. The pair in the middle of the connector will be blue. You want to exchange the far left pair with the middle pair (orange or green, with the blue).

Don't forget to configure one side as a DCE and supply clock.

Good Luck

it works, thanks

i should cross pin 1 with pin 4 and 2 with 5.

i don't need to configure one side to DCE. they worked now without any configuration.

thanks again.
