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.
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.
