CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label identifies certified equip-
ment. 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, ensure that it is permissible to be connected to the fa-
cilities of the local telecommunications company. The equipment must also be in-
stalled 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). 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 mainte-
nance facility designated by the supplier. Any repairs or alterations made by the user
to this equipment, or equipment malfunctions, may give the telecommunications com-
pany 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 contact 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.
