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

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 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 the devices does
not exceed 100.
