Notice to Users of the Canadian Telephone Network
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 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. 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 coordinated by a representative
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 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 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.
If your equipment is in need of repair, refer to the procedures described in the
next section.
