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.
CAUTION:
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.
