Canadian Department of Communications Requirements
The Canadian Department of Communications label identifies certified equipment.
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, 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 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 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 water pipe system, if present,
are connected together. This precaution may be particularly important in rural areas.
NOTE
Users should not attempt to make electrical ground connections themselves, but
should contact the appropriate electrician authority.
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 number of devices does not exceed one
hundred.
