When installation is complete you will have one or more
standard RJ-11 jacks on the inside of your building. Jacks are
the receptacles you plug your phone into.
Radio antenna unit
(RAU)
The RAU, which acts as a radio
receiver and transmitter,
connects the telephone with the
Globalstar satellites. It is
essential that the RAU antenna
have a clear view of the sky and
the horizon.
Junction box
The junction box connects outside cables to
the inside wiring. It also receives power from
your power supply and supplies power to the
RAU. The junction box and the grounding
rod provide the user with protection against
lightning strikes to the RAU and outdoor
cabling.
Power supply
The power supply is the one selected by the service
provider and the installer. The power supply
provides 12+ volts to the junction box and RAU.
Note: Your installer will have equipped your
installation with a power supply.
The installation is described in detail in
