Show the current parameter settings. Displays the set commands above and the following:
rxfreq
Current receiver frequency (KHz).
rftemp
rftemp
Radio temperature (Celsius).
rxrfrssi
rxrfrssi
Received RSSI.
rxlock
rxlock
Receiver lock mode.
0 - Disabled.
1 - Enabled.
txlock
Transmitter lock mode.
0 - Disabled.
1 - Enabled.
Notes:
1.
When specifying a single channel, enter the RF frequency in the 'hirffreq
n
' setting
and then enter the identical value in the 'lorffreq
n
' setting.
2.
Scanning ranges must not intersect or overlap.
3.
When changing settings, the order of data entry must ensure the 'hirffreq
n
' setting is
always greater than the 'lorffreq
n
' setting. For example, when changing from the
default setting (hirffreq
n
=lorffreq
n
=0) you must enter the hirffreq
n
setting first.
Frequency Scanning
Frequency scanning is performed in 250 KHz steps, monitoring each step for
Frequency scanning is performed in 250 KHz steps, monitoring each step for
approximately four seconds. The subscriber will always complete the entire scan for all
non-zero ranges. If all ranges are zero, the subscriber will scan the entire range of the
radio. During the scan, the subscriber compiles a table of detected base stations (filtered
by the bsidtable entries) and orders the results based on priority and then signal level
(CINR). Once the scan is completed, the table is saved in non-volatile RAM (preserved
through subscriber reboot/power-cycle).
A frequency scan is triggered by any of the following events:
A frequency scan is triggered by any of the following events:
1.
The RF parameters are modified.
2.
The bsidtable (allowed base station list) is modified.
3.
There are no base stations in the scanning results table.
Following any of the events listed above, the subscriber attempts to register with the first
base station in the scanning results table. If the subscriber is unable to register with a
base station, that entry is removed from the scanning results table. Once registered, the
subscriber remains connected to that base station. If the connection to the base station
is lost while the subscriber is online (e.g., base station rebooted), that base station is
removed from the scanning results table, and the subscriber attempts to register with the
next base station in the scanning results table. If the scanning results table becomes
empty, the scanning process is restarted.
