IC CS-03 requirements
NOTICE: The Industry Canada label identifies certified equipment. This certification means the
equipment meets certain telecommunications network protective, operational, and safety
requirements as prescribed in the appropriate Terminal Equipment Technical Requirement
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 for the
equipment 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 can 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) of this device is 0.7.
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 Number of all the devices does not exceed
five (5.0). The standard connecting arrangement code (telephone jack type) for equipment with
direct connections to the telephone network is CA11A.
