Get an "RJ-48 inline coupler" - this is basically two RJ-48 sockets wired back-to-back, and is normally used to join two shorter cables into a single longer cable. Get a "T1 loopback plug" - This is basically an RJ-48 plug with two wires; one wire connects pins 1 to 4, the second wire connects pins 2 to 5. Plug a cable from the line termination point in the room (the wall jack) to the P130. Wait about 60 seconds. If the line is not reporting "LA" [Link Active] then get the telco on the line. Get someone who can test the circuit - this can typically be done from the central office. Once you get the right person on the line - DON'T LET THEM GO until you are done. 1) Have them test the line [while plugged into the P130]. What do they see? Make sure they knock down any loopbacks they may be running. Even if they don't think there is one, make sure they send the signals to turn off any loopbacks that may have been set up previously. 2) Unplug the cable from the P130. Plug the cable into the coupler. Plug the loopback plug into the coupler. This is a "hard[wired] loop[back]". What do they see? 3) Unplug the loopback plug into the coupler. This is an open circuit. What do they see? 4) Disconnect the coupler from the cable and reattach the cable to the P130. What do they see? 5) With the cable on the P130, enable the [new in 5.1A] line loopback feature. Open the Mod Config > Nailed T1 menu, Set Loop Back=Line Loopback. What do they see? 6) Turn off the Line Loopback on the P130. What do they see? These tests can help to isolate the location of the problem.
