These boxes can generate 404, 1004, 2804, and 3804 Hz tones. I assume these tones are used when measuring line loss. Does anyone know for sure? Also, these boxes can generate a 2713 Hz tone for "activating a Bell 829 loopback device." Does anyone know how this works? Jason Hillyard 6600jrh@ucsbuxa.ucsb.edu
