Users should ensure 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.
CAUTION: Users should not attempt to make
such connections themselves, but should contact
the appropriate electric inspection authority, or
electrician, as appropriate. The Ringer Equivalent
Number is 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 Equivalent Number of all the
devices not exceed five.
