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.

Users should not attempt to make such connections themselves, but

should contract 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.
