ALE Call Weighting
When the quality of a channel is tested the channel is given an LQA score. The ALE Call
Weighting entry enables you to weight the scoring process according to the use of the
transceiver. For example, if the transceiver is mainly used to make voice calls you would
select Mostly voice. When Lowest acceptable is selected the transceiver will attempt a
call on the channel with the lowest frequency (with an LQA score above the set
threshold), then attempt the channel with the next higher frequency and LQA score etc,
until a link is established. In some situations where propagation distances may be less
than a few hundred kilometres, weighting the LQA scores in this way increases their
effectiveness.
ALE Golay
ALE control information is sent and received in blocks of data called ALE words. After
a word has been received, BER tested and accepted, the transceiver performs a Golay
test to check it for errors and correct it if necessary.
The number of error bits per word indicates the quality of the channel used to transmit
the word. Golay testing can detect and correct up to three error bits per ALE word. It can
also detect four error bits but is not guaranteed to correct all four. Note that excessive
errors can sometimes create false readings.
The ALE Golay entry enables you to specify the number of errors you will tolerate and
correct in this test, which indicates the quality of the channels on which you are prepared
to accept calls. Also see page 210, ALE BER.
ALE Hangup ALL Call
During an ALL call, a link is established implicitly without the receiving stations
responding to the initiating station. When the ALE Hangup ALL Call entry is enabled,
the initiating station will send a link termination sequence when SCAN is pressed. All
stations that entered the link will hang up the link and return to scanning when they
receive this sequence.
ALE LQA Average
When the transceiver periodically tests the quality of the channels in your network it
stores the results for future use. The transceiver uses an averaging method to reduce the
effect that the new reading may have on the current channel values.
CAUTION It is recommended that this entry is not altered from the factory setting.
