AT&T Private Pay Phone Plus
February, 1988
APPENDIX A
USE WITH ADDITIONAL PHONE
The AT&T Private Pay Phone Plus has the capability of allowing an additional telephone to
be linked to it. When another telephone is linked to the AT&T Private Pay Phone
Plus, both
the AT&T Private Pay Phone
Plus and the other telephone will ring when a call is made to
either phone. Either telephone can be used to answer the call, but once the call is
answered with one of the telephones the other cannot be used to listen in on the call. This
is also true when a call is made from the AT&T Private Pay Phone
Plus or the linked
telephone. (Note: The telephone that is not used when answering or making a call is "dead"
until the call is finished.) The AT&T Private Pay Phone
Plus operates this way because of a
special circuit that has been built into it. This circuit is called the Exclusion Circuit and it
assures privacy.
You may, however, "pass" a call between the pay phone and the additional, or remote,
telephone. To pass a call from the pay phone to the remote telephone, follow these steps:
• Take the remote telephone off-hook (pick up receiver)
• After about a second, hang up pay phone
To pass a call from the remote telephone to the pay phone, follow these steps:
• Take the pay phone off-hook (pick up receiver)
• At pay phone, press
* button
• After about a second, hang up remote phone
To link an additional telephone to the AT&T Private Pay Phone
Plus, a special adapter
(specifically an AT&T 2670 T-Adapter) is needed. You will also need a 4-conductor modular
telephone line cord. An AT&T 2670 T-Adapter and 4-conductor line cord (at various lengths}
can be purchased at any AT&T Phone Center.
One of two methods can be used to wire an additional telephone to your Private Pay Phone.
The method used depends on the distance between the Private Pay Phone and the
additional telephone. If the distance is
25 feet or less, use Method 1. If the distance is more
than
25 feet, use Method 2.
CAUTION
The methods and equipment outlined below will reduce the chance of loss of service when
connecting an additional telephone pay phone. All connections and wires should be
protected. Any deviation from the methods outlined above may cause loss of service and
damage to your Private Pay Phone. To prevent this from happening, you may want to have a
qualified telephone service technician install the wiring necessary to connect an additional
telephone to your Private Pay Phone.
METHOD 1: 25 Ft. Or Less
If 25 feet or less of 4-conductor telephone line cord is needed, the following items are used:
