Bad word count
Call Retry Limit
This option sets the maximum number of sequentially received bad ALE words which are
allowed before the ALE processor decides that the quality of the current channel is too poor
to establish an ALE link. A bad word is a word that has exceeded either the BER or Golay
Threshold.
The value can be set between 0 and 4.
If the test fails during the process of establishing the ALE link, the call aborts and the
transceiver returns to scan mode.
This option controls the number of times the ALE station tries to establish an ALE link using
each channel in turn form the scan group.
The limit can be set between 0 and 98. If 99 is selected this is interpreted as “no limit”.
On each selected channel, two attempts are made to establish a link before going onto the
next preferred channel, where two more attempts are made and so on, until all channels in
the scan table have been tried (unless a link is established).
The sequence is then repeated dependent upon call retry limit set above.
Note: Retry duration can be made up to one minute per channel.
