Industry Canada: Equipment attachment limitation
NOTICE: The Industry Canada Label identifies certified equipment. This certification
means that the equipment meets telecommunications network protective, operational,
and safety requirements as prescribed in the appropriate Terminal Equipment Technical
Requirements document(s). The Department does not guarantee that the equipment will
operate to the user’s satisfaction.
Before installing this equipment, you 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. You should be aware that
compliance with the above conditions might not prevent degradation in service in some
situations.
Repairs to certified equipment should be coordinated by a representative designated by
the supplier. Any repairs or alterations made by the user to this equipment, or equipment
malfunctions, can give the telecommunications company cause to request you to
disconnect the equipment.
You should ensure, for your 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 can be particularly important in rural areas.
Caution: You should not attempt to make such connections yourself, but should contact
the appropriate electric inspection authority, or electrician, as appropriate.
NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device
provides an indication of the maximum number of terminals allowed to be connected to
a telephone interface. The termination on an interface can consist of any combination of
devices subject only to the requirements that the sum of the Ringer Equivalence
Numbers of all the devices does not exceed 5.
