Industry Canada Compliance Information
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. In
some cases, the company's inside wiring associated with a single line individual service may be extended by means of
a certified connector assembly (telephone extension cord). 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 ensure for their own protection that the electrical ground connections of the power utility, telephone
lines and internal metallic waterpipe system, if present, are connected together. This precaution may be particularly
important in rural areas.
The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a
telephone loop which is used by the device, to prevent overloading. The termination on a loop may consist of any
combination of devices subject only to the equipment that the total of the LNs of all devices does not exceed 100.
The ringer equivalence number (REN) assigned to each terminal adapter is used to determine the total number of
devices that may be connected to each circuit. The sum of the RENs from all devices in the circuit should not exceed
a total of 5.0.

the equipment meets certain telecommunications network protective, operational, and safety
requirements. The Department of Commerce does not guarantee the equipment will operate to the
user's satisfaction.
Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or an electrician, as appropriate.
