[sci.electronics] Toll restrictors, pay phones

wtm@neoucom.UUCP (Bill Mayhew) (05/25/89)

Putting up a pay phone in one's place of business can be a risky
proposition.  There are some companies around that don't care who
gets left holding the bag for an uprofitable pay station; often it
is the customer that gets burned.  Careful research is advised.
There are many goverment regulations that pay stations must comply
with, thus installation is not a do-it-yourself operation.

Toll restrictors are quite readily available to prevent dialing out
into unauthorized exchanges or long distance.  Smart units also
prevent users from dialing by pulsing the hookswitch.  I have a
friend who buys outgoing WATS for a business run from his home.  I
believe the carrier is a comany named Light-tel (or similar).  The
service includes a toll restrictor/ number converter that functions
transparently.  Local calls are passed without discernible delay,
while long distnace calls are forwarded to the WATS by adding a
prefix.  The whole thing is transparent to the end user, but can be
bypassed by dialing a security code for direct access to the line.

Toll restrictors are inexpensive enough that it is easier to just
buy one instead of building ... unless you enjoy construction for
the hobby aspect.
