NOTICE
The Industry Canada label identifies certified equipment. This certification means that
the equipment meets certain telecommunications networks protective, operational
and safety requirements. 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. 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.
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 requirements that the total of the Load Numbers of all the devices
does not exceed 100.
