CANADIAN EQUIPMENT LIMITATIONS
The Industry Canada Certification label identifies certified equipment.
This certification means that the equipment meets certain telecommu-
nications network 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 permissi-
ble to be connected to the facilities of the local telecommunications com-
pany. 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 cer-
tified 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 Cana-
dian maintenance facility designated by the supplier. Any repairs or al-
terations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to re-
quest 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.
Users should not attempt to make such connections themselves, but should con-
tact the appropriate electric inspection authority, or an electrician, as appropri-
ate.
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 adapt-
er is used to determine the total number of devices that may be connect-
ed to each circuit. The sum of the RENs from all devices in the circuit
should not exceed a total of 5.0.
