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 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.
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 procedure on page A of this document.
