Preface
Compliance
Certification Notice for Equipment Used in Canada
The Canadian Department of Communications label identifies certified
equipment. This
certification means that the equipment meets certain telecommunications-network
protective, operation, 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 (extension
cord). The customer should be aware that 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 maintenance facility—in
this case, your 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.

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 the devices does not exceed 100.
