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, 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 limitations 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 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.
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.
Users should not attempt to make such connections themselves, but should contract the
appropriate electric inspection authority, or an electrician, as appropriate.
