[comp.dcom.telecom] Question About Test Tones

Jason Hillyard <6600jrh@ucsbuxa.ucsb.edu> (04/30/91)

While flipping through the Specialized Products catalog of telecom
gear, I saw several devices called "Analog Test Sets" which were
capable of generating certain tones for testing purposes.

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?
