Canadian Equipment Limitations
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. In some cases, the company's inside wiring
associated with a single line individual service may be
extended by means of a certified connector assembly
(telephone extension cord). The customer should be
aware that compliance with the above conditions may
not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an
authorized Canadian maintenance facility 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 re-
quest the user to disconnect the equipment.
Users should ensure for their own protection that the
electrical ground connections of the power utility, tele-
phone lines and internal metallic waterpipe system, if
present, are connected together. This precaution may be
particularly important in rural areas.
The Load Number (LN) assigned to each terminal de-
vice denotes the percentage of the total load to be con-
nected to a telephone loop which is used by the device,
to prevent overloading. The termination on a loop may
consist of any combination of devices subject only to the
equipment that the total of the LNs of all devices does
not exceed 100.
The ringer equivalence number (REN) assigned to each
terminal adapter is used to determine the total number
of devices that may be connected to each circuit. The
sum of the RENs from all devices in the circuit should
not exceed a total of 5.0.
NOTE
The Industry Canada Certification label identifies
certified equipment. This certification means that
the equipment meets certain telecommunications
network protective, operational, and safety
requirements. The Department of Commerce does
not guarantee the equipment will operate to the
user's satisfaction.
CAUTION
Users should not attempt to make such connections
themselves, but should contact the appropriate
electric inspection authority, or an electrician, as
appropriate.
