MultiVOIP Gatekeeper User Guide
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 MULTIMODEMISI 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.
