xiv Users Manual
Telecommunications per DOC notice
(for products fitted with an IC-compliant modem)
The Industry Canada 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 users’ satisfaction.
Before installing this equipment, users should make sure 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
inside wiring associated with a single-line individual service may be extended by
means of a certified connector assembly. 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 designated by the 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 make sure, 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.
To avoid electrical shock or equipment malfunction do not attempt to make
electrical ground connections by yourself. Contact the appropriate inspection
authority or an electrician, as appropriate.
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 may consist of any combination of
devices subject only to the requirement that the sum of the Ringer Equivalence
Numbers of all the devices does not exceed 5.
