Label the jacks at each location.
Identify and label the jacks at each location to avoid the possibility of improperly connecting any
of the lines to the telephones. To do so, write the line number(s) directly on each jack plate with
a felt-tip pen.
For example:
If you have difficulty in identifying wall jacks.
Call the vendor who installed the inside wiring and ask for assistance in identifying your existing
wiring system and jacks.
If you are installing new wiring and jacks.
If any new telephone wiring and modular jacks need to be installed, and four lines are to be used,
install two-line RJ14 jacks at each telephone location. Each RJ14 jack accommodates two tele-
phone lines.
