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
document(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.”
