Yes. At that point, you're looking for a T1 "cross-over".
The pinout is as follows: 1 4 RX/Ring/- <-->TX/Ring/- 2 5 RX/Tip/+ <-->TX/Tip/+ 4 1 TX/Ring/- <-->RX/Ring/- 5 2 TX/Tip/+ <-->RX/Tip/+ 3 3 Shield/Return/Ground 6 6 Shield/Return/Ground On 3/18/07, Jeronimo Romero <[EMAIL PROTECTED]> wrote:
I assume that I would need to cross these pins over if I were going from t1 card to t1 card.

T1s use 1 and 2 (rx tip and ring) and 4 and 5 (tx tip and ring) for signals. A T1 loopback plug would be wired 1 to 4 and 2 to 5. They come in handy for testing T1 cards or for providing a hard loop for the telco.
