AT&T Private Pay Phone Plus
February, 1988
Select the following telephone services from your local telephone company:
• Local service
• Long distance service
• Do not select any Custom Calling features, such as Call Waiting.
• As a deterrent against fraud, if your local telephone company offers the service, you may
want to subscribe to a feature that prohibits operator assist•:?d calls from being charged
to the pay phone line. Only direct dialing charges should be charged to the line.
Reversed charges, 3rd party charges, and collect calls to the AT&T Private Pay Phone
Plus should not be allowed. Check with your local telephone company to make sure that
your line has such a feature, if available.
NOTE- State P.UC. regulations may specify that the AT&T Private Pay Phone Plus has to be
connected to a special telephone line. Check with your local telephone company.
Electrical Service
The AT&T Private Pay Phone Plus connects to a 110-volt outlet for power. A 30-foot power
cable has been provided as part of the phone package. The 110-volt outlet must be within
30 feet of the AT&T Private Pay Phone
Plus if you are using 22-gauge wire. If you use 20-
gauge wire, the maximum distance is 48 feet, and if you use 18-gauge wire the maximum
dista,1ce is 76 feet (only one wire is needed for the "CT" connection when using 18-gauge
copper wire). Exceeding these maximums may prevent the phone from receiving enough
power to operate.
If necessary, install (or have installed) an electrical outlet nearer the phone. Be sure the
outlet can be protected against unauthorized access.
Grounding
The AT&T Private Pay Phone Plus must be grounded for proper operation and electrical
safety. Also, the phone's ground must be bonded (electrically connected) to the ground used
for 110-volt power and telephone service.
WARNING
Failure to ground and bond the pay phone 110-volt electrical power and telephone service
properly can result in risk of dangerous electrical shock from lightning. If secure grounds
can not be obtained as explained below, contact a qualified electrician to do the service.
Grounding the AT&T Private Pay Phone Plus
The ground at the AT&T Private Pay Phone Plus can consist of one of the following:
• A ground wire connected to the phone directly. (The phone has a location for
attachment of a ground wire.) Refer to Figure 3.
• A ground wire connectea to a phone enclosure. (The AT&T enclosures have a location
for attachment of a ground wire.)
• A pedestal mount that is attached to a concrete encased ground, as defined in No. 5,
below. If in doubt that a concrete base is grounded, use a ground wire.
When a ground wire is required, we recommend a 14-AWG or larger copper wire with no
splices. Use the shortest possible length of ground wire. The ground wire is not supplied
with the AT&T Private Pay Phone
Plus.
