Note
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.
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 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.
Users should not attempt to make such
connections themselves, but should contact the appropriate electric
inspection authority, or electrician, as appropriate.
Note
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 Number of all the devices does not
exceed 5.
