EQUIPMENT ATTACHMENT LIMITATIONS
(For Canada Only)
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 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.
Caution:
Users should not attempt to make such connections themselves,
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
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 REN=0.3
