Users should make sure, for their own protection, that the electrical ground connections of the power utility,

telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution may

be particularly important in rural areas.

The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the

maximum number of terminals allowed to be connected to a telephone interface. The termination on an

interface may consist of any combination of devices subject only to the requirement that the sum of the Ringer

Equivalence Numbers of all the devices does not exceed 5.

Warning To avoid electrical shock or equipment malfunction do not attempt to

make electrical ground connections by yourself. Contact the

appropriate inspection authority or an electrician, as appropriate.
