If a Digital Communicator is
Connected to a Telephone Line:
Do not notify the telephone company. It
is no longer necessary to call the telephone
company to notify it of the registration and
ringer equivalence numbers of anY
telephone instrument being connected to
the public switched telephone network.
The telephone company will call and re-
quest this information if a need arises in
the future.
Ringer Equivalence Number.
The FCC Registration I-abel, found on
top of your system and on the bottom of
your telephone sets, includes the ringer
equivalence number (REN). This is a rep-
resentation of the electrical load that will
be applied to your telephone line. This sys-
tem has a ringer equivalence of zero.
Therefore, it does not affect the load of the
telephone company central ofFtce equiP-
ment when your telephones ring. The
telephone line servicing your premises will
not operate properly if the total ringer load
exceeds the capability of the central office
equipment. That is, if too many ringen are
connected to the line, there may be insuf-
ficient enerry to ring your telePhones. If
the ringer load is excessive, you may also
have difficulty dialing telephone numbers.
If you want to know the total REN al-
lowed for your telephone line, you may call
your telephone comPany. However, as a
rule of thumb, a total REN of five (5)
should permit normal operation of your
telephone sets and equipment. To deter-
mine the total ringer load, list the REN of
each of your telephone sets or devices con-
nected to your telephone line. Add these
numbers; the result is the total REN for
your line. If this number exceeds 5, you
may want to consult your telephone com-
pany to determine whether or not ProPer
operation of your equipment is possible.
Rights of the Telephone Com'
pany
If your digital communicator causes
harm to the telephone network, the
telephone comPany may discontinue your
service temporarily. If possible, they will
notify you in advance. But if advance
notice is not practical, you will be notified
as soon as possible. You will be given the
opportunity to correct the situation and
you will be informed of your right to file a
complaint with the FCC.
Your telephone company may make
changes in its facilities, equipment, opera-
tions or procedures that could affect the
proper function of your communicator. If
they do, you will be notified in adrance to
give you an opportunity to maintain
unintemrpted sewice,
