AT&T Private Pay Phone Plus
February, 1988
• If you are using the "groove" method, determine where groove should go and
groove surface. (Note: A groove may not be necessary if you are using a 178A
Backboard, and do not plan to drill a hole through the wall. Refer to Figure 7.)
• Drill all necessary holes.
7. Lay Power Cable, Ground Wire, and Telephone Line Cord
• Lay the power cable, ground wire, and 2-conductor telephone line cord. If a hole
was drilled through the wall, put them through hole. If a groove was placed on the
wall, channel them along groove. (You may need to tape the cable, wire, and line
cord down in groove.) In either case, make sure they can reach their respective
connections. Refer to Figure 6.
8. Mount AT&T Private Pay Phone
Plus Housing
• If a backboard is being used, place the electrical power cable, ground wire, and 2-
conductor telephone line cord through the wire entrance hole on backboard. Then
mount the backboard to the surface. Install the four security studs (shipped loose)
into the back of the_ phone.
• Place electrical power cable, ground wire, and 2-conductor telephone line cord
through wire entrance hole in phone (outside to inside). Refer to Figure 7.
• If the rubber grommet is not already cut, use a pair of scissors or a utility knife to
cut the hole in the grommet part of the way up and part of the way down. The
grommet is there to keep out moisture and dust, so don't cut more than necessary.
Bring electrical power cable, ground wire, and telephone line cord through center
hole of grommet. Refer to Figure 10.
• Place rubber grommet back into base housing (thus sealing the opening in the back
of the base housing). See Figure 10.
• If a backboard is being used, place the security studs protruding from the back of
the phone into the keyhole slots on the backboard and let the phone drop into
position. Screw the phone to the backboard using the seven mounting screws
shipped with the phone (see Figure 9).
• If a backboard is not being use, have an assistant hold the phone's housing against
mounting surface with holes aligned. Insert screws (make sure the phone is
vertical -- Table 1) and tighten. The phone housing should now be firmly mounted
against surface.
