Canadian Limitations Notice
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
of a 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 certificated equipment. This certification means that the
equipment meets certain telecommunications network protective, operational and safety requirements.
The Industry Canada does not guarantee the equipment will operate to the users 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.
Compliance with BABT Requirements
Approved for connection to telecommunications system specified in the instructions for use subject to the
conditions set out in them.
Warning: Interconnection directly, or by way of other apparatus, of ports marked "SAFETY WARNING see
instructions for use" with ports marked or not so marked may produce hazardous conditions on the network.
Advice should be obtained from a competent engineer before such a connection is made.
It is a condition of approval that the power required by the host and the total of all adapter cards installed
within the host environment, together with any auxiliary apparatus, does not exceed the power specification as
stated in the Technical Reference Material of the host apparatus.
The power requirements for the MultiModem ISI are:
Modem operating voltages: +12V D.C., -12V D. C., +5V D.C.
Modem power consumption: 8 Watts
In order to maintain the independent approval of this card, it is essential that when other option cards are
introduced which use or generate a hazardous voltage, the minimum creepages and clearances specified in the
following table are maintained. A hazardous voltage is one which exceeds 42.4V peak a.c or 50V d.c. If you have
any doubt, seek advice from a competent engineer before installing other adapters into the host equipment.
The equipment must be installed such that with the exception of connection to the host, clearance and creepage
distances shown in the following table are maintained between the card and any other assemblies which use or
generate a voltage shown in that table. The larger the distance shown in brackets applies where the local
environment within the host is subject to conductive pollution or dry nonconductive pollution which could
become conductive due to condensation. Failure to maintain these minimum distances would invalidate
approval.
