RINGER EQUIVALENCE (REN)
The REN is used to determine the quantity of devices which may be connected to the
telephone line. Excessive RENs on the telephone line may result in the devices not ringing
in response to an incoming call. In most but not all areas, the sum of the RENs should not
exceed 5.0. To be certain of the number of devices that may be connected to the line, as
determined by the number of RENs, contact the telephone company to determine the
maximum REN for the calling area.
INCIDENCE OF HARM
If the terminal equipment, the DCS 400si, causes harm to the telephone network, the
telephone company will notify you in advance that temporary discontinuance of service
may be required. But if advance notice is not practical, the telephone company will notify
the customer as soon as possible. Also, you will be advised of your right to file a complaint
with the FCC if you believe it is necessary.
CHANGES TO TELEPHONE COMPANY EQUIPMENT OR FACILITIES
The telephone company may make changes in its facilities, equipment, operations or
procedures that could affect the operation of the equipment. If this happens, the telephone
company will provide advance notice in order for you to make the necessary modifications
so that you may maintain uninterrupted service.

is subject to state tariffs.
The DCS 400si system uses toll restriction and LCR features that are programmed to
allow dialing over the public telephone network. The North American Numbering Plan
(NANP) determines these network area codes and exchange codes. Failure to update the
system programming or software may deny you access to new area codes and exchanges.
Bell Communication Research (Bellcore) administers the NANP and publishes it. To ob-
tain the latest information and keep your system current, contact Bellcore at (201) 829-
