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.
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.
