CERTIFICATION NOTICE FOR TELEPHONE EQUIPMENT USED IN CANADA
The Industry Canada label identifies certified equipment. This certification means
that the equipment meets certain telecommunications-network protective,
operation, and safety requirements. Industry Canada 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
might not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian
maintenance facility—in this case, Black Box. 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.
