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 degrada-
tion 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 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.
Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or an electrician, as
appropriate.
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
requirement that the total of the Load Numbers of all devices does not exceed 100.
