Items (b) and (d) are indicated on the label. The Ringer Equivalence Number (REN) is
used to determine how many devices can be connected to your telephone line. In most
areas, the sum of the REN of all the devices on any one line should not exceed 5.0. If
too many devices are attached, they may not ring properly.
Industry Canada Required Information
EQUIPMENT ATTACHMENTS LIMITATIONS
To ensure that certified equipment is attached correctly and only to the networks of
participating carriers, the following statement shall accompany each unit of certified
equipment offered for sale. This statement must be included conspicuously in written or
electronic format, at or near the front of each copy of the operating manual, or
accompany other technical information, or be included as a separate sheet. The
required statement is:
“
NOTICE : The Industry Canada label identifies certified equipment. This certification
means that the equipment meets telecommunications network protective, operational
and safety requirements as prescribed in the appropriate Terminal Equipment Technical
Requirements documents(s). The department does not guarantee the equipment will
operate to the user’s satisfaction.”
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment
must also be installed using an acceptable method of connection. The customer should
be aware that compliance with the above conditions might not prevent degradation of
service in some situations.
Repairs to certified equipment should be coordinated by a representative designated by
the supplier. Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request
the user to disconnect the equipment.
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.”
An explanatory note on Ringer Equivalence Numbers (see Section 10.0) and their use
must be provided for the terminal equipment user in the information accompanying the
terminal equipment. A notice similar to the following would be suitable:
“
NOTICE : The Ringer Equivalence Number (REN) assigned to each terminal device
provides 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 equivalence
Numbers of all the devices does not exceed 5.”
