Notice: The Canadian Industry and Science Canada label identifies certified
equipment. This certification means that the equipment meets certain telecommu-
nications network protective, operational, and safety requirements. The Depart-
ment 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 equip-
ment must also be installed using an acceptable methods of connection. In some
cases, the company’s inside wiring associated with a single line individual service

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 main-
tenance facility designated by the supplier. Any repairs or alterations made by the
user to this equipment, or equipment malfunctions, may give the telecommunica-
tions company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connec-
tions 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.
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 combina-
tion 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 contract the appropriate electric inspection authority, or an elec-
trician, as appropriate.
