[mod.telecom] Aftermarket pay phones

AWalker@RED.RUTGERS.EDU (*Hobbit*) (11/25/86)

I forget exactly who makes them, but a local diner has implemented these non-
AT&T pay phones.  They look similar except that the insert cards are done in
brown, the handset is black and extremely *heavy*, and the locks on the cash
box are the "TuBar" type.  I believe the manufacturer is Continental Comm
or some such; probably something related to Northern Telecom.  Anyway, you
pick up the hanset and get a dialtone generated by the phone itself, and as
you punch buttons a voice synth says "Two, Six, Seven, Four, ..." which takes
an annoyingly long time over a sequence of many digits, but at least you *can*
type ahead of the voice and let it buffer out.  It then asks, with the same
voice synth, for money.  *No* ACTS hookup.  Once money is inserted, or when
completing a free call, a dialer unit inside picks up the real line, dials the
sequence, and completes.  It is possible to hear the dialing softly in the
background; it is not doing anything funny like dialing an alternate carrier's
switch and then a code and your number.  It dials directly so this indicates
that the line behind it is normal.  It senses line voltage and resets when
the line voltage drops to return dialtone, so simply waiting for it to time
out won't bypass its internal billing mechanism.

The most hilarious part is the ordinary modular jack located under the shelf
it's mounted on.  Obviously these things would never survive outside... Anyway,
when you do the usual hack of dialing Directory or something and then yanking
the plug underneath to return outside dial tone, it voices "Error 4" or some
such at you.  I'm willing to bet it has all kinds of nifty diagnostic modes
you could put it into using the dial.
