NOTICE
The Industry Canada label identifies certified equipment. This
certification means that the equipment meets certain telecommunications
networks 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 conditions may not prevent
degradation of service in some situations.
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
requirements that the total of the Load Numbers of all the devices does
not exceed 100.
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 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 electrician,
as appropriate.
