Notice for Canadian installations
The Industry 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 that the equipment will operate to the user’s satisfaction.
The Load Number (LN) assigned to each terminal device is the percentage of
the total load that can be connected to a telephone loop using the device. This
number prevents overloading. The termination on a loop can consist of any
combination of devices, provided that the total of the Load Numbers does not
exceed 100. An alphabetic suffix is also specified in the Load Number for the
appropriate ringing type (A or B), if applicable. For example, LN = 20 A
designates a Load Number of 20 and an “A” type ringer.
Before installing any equipment, users should ensure it is permissible to be
connected to the facilities of the local telecommunications company. The
equipment must 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
telephone 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.
