The service is provided by SBC/AT&T.  The intended market is
Payphone Service Providers (i.e. COCOT operators) who want to
use real payphones using telco-side billing/control (ACTS) rather
than internal logic.  I use it simply because I have a couple
2C2s (one is new-old stock!) a 1D2, and a 2D2.

It's kind of expensive, about 65$/month after taxes.

No, I haven't tried putting more than one payphone on it at a
time.  At worst, I suspect it wouldn't work at all (since the
coin tests wouldn't work right) and at best, it'd be odd, since
the coin relay in all connected phones would actuate in unison.

Oh, it's not a 17Q, it's a 1PC (the 17Q is, electrically, no
different from a regular business phone line, it's the 1PC
that has the coin signaling).  The 17Q is what they delivered
at first, in error.

Dunno who your telco is, but for SBC/AT&T, go here:
https://primeaccess.att.com/  (and click on "Payphone")

That site is interesting.  You can buy pretty much anything
these days from AT&T if you're willing to pay for it.  Such a
change from the bad old days when the telcos were fortresses
and you couldn't so much as order Touch-Tone service without
proving that you hadn't stolen one of their Touch-Tone phones.
