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
numbers of all the devices does not exceed 5.
Notice: The Industry Canada label identifies certified equipment. This
certification means that the equipment meets certain
telecommunications 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
permissible 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 made by an authorized Canadian maintenance
facility 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
may 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.
