CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label identifies certi-
fied equipment. This certification means that the equipment meets certain
telecommunications network protective, operational, and safety require-
ments. 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 con-
nected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of connec-
tion. 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 condi-
tions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadi-
an maintenance facility designated by the supplier. Any repairs or alter-
ations 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 wa-
ter 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 per-
centage 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 con-
sist 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 contact the appropriate electric inspection authority,
or an electrician, as appropriate.
