REQUIREMENTS
Industry Canada has established rules that permit this telephone system
to be directly connected to the telephone network. Prior to the connection
or disconnection of this telephone system to or from the telephone
network, the telephone company must be provided with the following
information.
1. Your telephone number:
2. IC Certificate number: 140 7942 A
3. Ringer Equivalence Number (REN) of the equipment: 2.1
The Industry Canada label identifies certified equipment. This certification
means that the equipment meets certain telecommunications network
protective, operational and safety requirements as prescribed in the
applicable Terminal Equipment Technical requirements document(s). The
Department does not guarantee that equipment operates to user
satisfaction.
Before installation, the user should ensure that it is permissible to connect
this equipment 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, when 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 applicable electric inspection authority, or electrician.
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 of an interface may
consist of any combination of devices subject only to the requirement that
the sum of the Ringer Equivalent Numbers of all the devices does not
exceed 5.
