CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label identifies
certified equipment. This certification means that the equipment
meets certain telecommunications network protective, operational,
and safety requirements. The Department does not guarantee the
equipment will operate to the user’s satisfaction.
Before installing this equipment, 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). Compliance
with the above conditions may not prevent degradation of service in
some situations.
Repairs to certified equipment should be made by an authorized Ca-
nadian maintenance facility designated by the supplier. Any repairs
or alterations made by the user to this equipment, or equipment mal-
functions, 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, telephone lines, and internal metallic
water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected 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 re-
quirement that the total of the Load Numbers of all devices does not
exceed 100.
Users should not attempt to make such connections
themselves, but should contact the appropriate electric
inspection authority, or an electrician, as appropriate.
