4.3.13 rfConfig - RF Setup Commands
The rfConfig mode allows you to view and modify the subscriber RF settings. The
following table lists all commands available in this mode.
Important: The subscriber must be rebooted before changes to the rfConfig frequency
settings become effective

Frequency Scanning
Scanning ranges must not intersect or overlap. When changing settings, the order of data
entry must ensure the 'Hi' setting is always greater than the 'Lo' setting. For example,
when changing from the default setting 'Hi=0, Lo=0' you must enter the Hi setting first.
The subscriber always performs a frequency scan at power-on or reboot. Scanning is
performed using 250 KHz steps, monitoring each step for approximately one second. If
there are no bsIdTable entries at power-on/reboot, the subscriber will always complete
the entire scan for all entered ranges. Unlisted base stations are added to the bsIdTable in
order based on signal level (CINR). When the scan is completed, the subscriber will
attempt to register with the base station having the best signal quality. If no base stations
were detected, or the subscriber is unable to register with any detected base station, the
scan is repeated.
If bsIdTable entries exist at power-on/reboot, the scan is stopped immediately when any
base station listed in the bsIdTable is detected, and the subscriber will attempt to register
with that base station. If the subscriber is unable to register with any detected base
station, the scan is repeated.
