56K/DS0 loopback plug - 04/28/10 10:41 PM
It has been quite some time since I've had to turn-up and test DS0's, but I am needing a loopback plug to test a 56K circuit. I have my circuit terminated on a RJ48S, using R1 on pin 1, T1 on pin 2, T on ping 7, and R on pin 8. I was reading on the forums that the loopback connects pins 1-7 and 2-8. Shouldn't the proper loopback on this actually be 1-8 and 2-7?
