MODULAR JACKS
To install your telephone, you must have a modular wall jack
at the desired location. If your telephone line does not have a
modular jack, you must have one installed.
DANGER: To reduce the risk of electrical shock
and personal injury, observe the following when
installing station wiring:
1. Never install telephone wiring during a
lightning storm.
2. Never install telephone jacks in wet locations
unless the jack is specifically designed for
wet locations.
3. Never touch uninsulated telephone wires or
terminals unless the telephone line has been
disconnected at the network interface.
4. Use caution when installing or modifying
telephone lines.
Various types of modular wall
jacks are shown to the right.
The USOC RJ11C modular
wall jack is for desk tele-
phones and the USOC RJ11W
modular wall jack is for modu-
lar wall telephones.
The USOC RJ11W modular
wall jack must be in the cor-
rect mounting position before
mounting a modular wall tele-
phone. Check to make sure it
is in the position shown.
