1740 SHDSL 2/4-Wire Router User’s Guide
The Ringer Equivalence Number (or REN) is used to determine the number of devices that may be
connected to a telephone line. Excessive RENs on a telephone line may result in the devices not ringing
in response to an incoming call. In most but not all areas, the sum of RENs should not exceed five (5.0).
To be certain of the number of devices that may be connected to a line, as determined by the total RENs,
contact the local Telephone Company. The REN for this product is part of the product identifier that has
the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point. For
example, 03 represents a REN of 0.3.
If the modem 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.
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 necessary modifications to maintain uninterrupted service. If trouble is
experienced with the modem, refer to the repair and warranty information in this document.
If the equipment is causing harm to the telephone network, the Telephone Company may request that you
disconnect the equipment until the problem is resolved.
The user may make no repairs to the equipment.
Connection to party line service is subject to state tariffs. Contact the state public utility commission,
public service commission or corporation commission for information.
If the site has specially wired alarm equipment connected to the telephone line, ensure the installation of
the modem does not disable the alarm equipment. If you have questions about what will disable alarm
equipment, consult your Telephone Company or a qualified installer.
