My current G450 gateway has the PRI line connecting to it via an adtran device. It was left over from when there was an IP Office at this location and never was removed when the gateway was installed. I am trying to remove this out of the configuration now but I can't seem to get the PRI to come up after it is removed. I have the board programmed, hopefully correctly, and have tried a standard Cat 5 cable from the demarc to the board and have also tried the T1 crossover cable. Nothing will bring the line up until the adtran is back in place. I can't figure out what I am missing so I am hoping someone in this forum can help me out. Thank you!
