In my travels through the building's fern closets recently, while mapping
how they wired this place, I found the following scribbled on the wall:
800-352-4732
0480 + phone no.
Naturally, I tried it [with a touch-tone set, or course!]. When the 800
number answers, it gives a brief tone, around 1350 Hz [?]. Upon entering
0480, it rings once and gives three more tone bursts. Entering a subsequent
number, with or without area code, delays for a bit, feeps a few more times,
and goes to a weird busy tone. Terminating the subsequent number with ''#''
eliminates the timeout.
Ideally, this thing could be a voice-synth database that would tell you the
current cable/pair numbers for a given line. I believe that I give NJ Bell
too much credit by assuming that they would actually have something like
that set up. Anyone have any idea what this thing really is?

I have heard tales of a device called a Dialed Number Recorder [DNR] that
the telco sometimes places on a line to record any and all touch-tone
digits dialed, whether to dial an initial call or after it's connected.
The purpose is apparently to log activities of fone hackers and build a
case against them in event of toll fraud, etc. It seems to me that such
a device would permit any telco employee free access to your personal
carrier passwords, banking services, and anything else you might do over
the fern using touch-tones. Is this legal? Does anyone know more about
these devices, what they do, and when they may be placed on a line?
