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.
