AT&T Private Pay Phone Plus
APPENDIX B
USE BEHIND PBX
February, 1988
Because of the way some PBX systems interface with the network, the AT&T Private Pay
Phone
Plus may not work with your system. There are many kinds of PBX systems, and the
only way to be sure
if the phone will work installed behind a particular system is to discuss
the installation with your dealer. Following are some general guidelines:
1. Check the P.U.C. regulations for your state. There may be restrictions on installing a
pay phone behind a PBX.
2. You cannot install the pay phone behind PBX's without outward dialing capability and
enough lines to handle all the calls on the syste!11 most of the time. The pay phone will
abort a call if a line is not available. The phone may be programmed for a PBX access
code, if necessary.
3. You cannot install the pay phone behind a PBX system without direct inward dialing
capability. The phone must be accessible via its own telephone number so that it can
be programmed.
4. You cannot install the pay phone behind a low voltage PBX system. The phone
requires 25 volts on-hook.
5. You cannot install the pay phone on a PBX system with auto-route selection. Choosing
a route may take too long to establish a call and the phone will abort the call.
6. Do not include the pay phone telephone number in a PBX hunt group.
7. Administer the pay phone number without call waiting, call forwarding, or toll
restriction features.
8. Because of the way some PBX's interface with the network, use touch tone dialing
only.
