NVOY™ TRANSCEIVER REFERENCE MANUAL
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 that will be
tolerated and corrected in this test, which indicates the quality of the channels on
which you are prepared to accept calls.
Range: 0 to 4
Default value: 2
CAUTION: It is recommended that this entry is not altered from the default setting.
ALE Hangup ALL Call
The ALE Hangup ALL Call entry sets whether or not the initiator of an ALL call
can hang up the call to all linked stations.
During an ALL call, a link is established implicitly without the called stations
responding to the calling station. When the ALE Hangup ALL Call entry is set to
Enabled, the calling station sends a link termination sequence when SCAN is
pressed. All stations that entered the link hang up the link and return to scanning when
they receive this sequence.
Default value: Enabled
ALE Hangup Phone Call
The ALE Hangup Phone Call entry sets whether or not a member of an ALE link
to an automated radio/telephone interconnect unit sends a link termination sequence
when SCAN is pressed.
During any ALE Phone call, a link is established between the calling station and the
station with an automated radio/telephone interconnect unit, for example, a Codan
3033 Telephone Interconnect. When the ALE Hangup Phone Call entry is set to
Enabled, all stations receive a link termination sequence when SCAN is pressed at
one of the stations. All stations that entered the link hang up the link and return to
scanning when they receive this sequence. This value may be required in ALE/CALM
HF networks with an automatic interconnect unit.
If the ALE Hangup Phone Call entry is set to Disabled, a link termination
sequence is not sent when SCAN is pressed at any of the stations in the link. In this
case, a hangup sequence must be sent separately to the radio/telephone interconnect
unit to clear the telephone line, or it hangs up after a timeout period.
Default value: Enabled
