4.1.1 Plan FSU Configuration
The FSU must be configured at subscription time with the subscriber’s
telephone number, authentication key, operator ID, and carrier channel. The
subscriber’s data must also be entered into the COT. The following data must
be entered for each subscriber:
• Telephone number
• Authentication key
• FXO port
RP numbers of the RPs having the control channel for each FSU must also be
entered in the COT. The RP numbers are determined either by the Coverage
Map or by the installer at the subscriber’s site. Once the FSU main unit and
antenna are installed, the installer uses the PHS Field Analyzer or equivalent
to determine which RP’s signal is received by the FSU. This is accomplished
by measuring the Received Signal Strength (RSS). Some FSUs will receive
signals from multiple RPs, the installer must identify them and measure their
RSS. Once RP number(s) are configured in the COT for the FSU, these RPs
become the only RP(s) through which the FSU can place and receive calls.
Refer to Section 4.2 for additional information regarding FSU configuration
instructions.
Use local procedures to ensure that the COT’s System Administrator gets the
RP numbers and the associated telephone numbers for entry into the COT.
Until an FSU’s RP numbers are configured in the COT, it will use any
available RP for placing and receiving calls.
4.1.2 Antenna Orientation
Careful placement of the antenna is necessary to ensure clear reception.
Position the antenna so that it is :
• In clear view of a Radio Port
• Not blocked by buildings, summer foliage nor heavy traffic
of large vehicles
• At least 2 meters in height, use Coverage Map and on-site
measurements to determine exact height, usually 2 meters
or higher
• Directed towards the strongest RSS measurement, for
directional antenna only
