Telephone Company Procedures: The goal of the telephone com-
pany is to provide you with the best service it can. In order to do
this, it may occasionally be necessary for them to make changes
in their equipment, operations or procedures. If these changes
might affect your service or the operation of your equipment, the
telephone company will give you notice, in writing, to allow you to
make any changes necessary to maintain uninterrupted service.
In certain circumstances, it may be necessary for the telephone
company to request information from you concerning the equip-
ment which you have connected to your telephone line. Upon
request of the telephone company, provide the FCC registration
number and the ringer equivalence number (REN); both of these
items are listed on the equipment label. The sum of aII of the
REN’s on your telephone lines should be less than five in order to
assure proper service from the telephone company. In some cases,
a sum of five may not be useable on a given line. Consult your
telephone provider.
If Problems Arise: If any of your telephone equipment is not oper-
ating properly, you should immediately remove it from your tele-
phone line, as it may cause harm to the telephone network. If the
telephone company notes a problem, they may temporarily dis-
continue service. When practical, they will notify you in advance of
this disconnection. If advance notice is not feasible, you will be
notified as soon as possible. When you are notified, you will be
given the opportunity to correct the problem and informed of your
right to file a complaint with the FCC. Contact your local telephone
service provider if you have any questions about your phone line.
