MICOM-2ES/2RS/2TS ALE Supplement to Owner's Guide
Receiving and Transmitting Calls in ALE Mode
The MICOM 2 supports the following types of ALE calls in accordance with
Individual call – call directed to a specific station.
Net call – call directed to a net (a net is a preprogrammed group of stations).
Group call – call directed to a group of stations.
AllCall – call directed to all other stations simultaneously (broadcast call); can
also be used as a distress call.
AnyCall – call directed to all other stations simultaneously, usually used to
detect new stations.
Wildcard call – call simultaneously addressed to a selected group of stations
within a net, with wildcards used within the address to specify the desired
stations. For efficient use of wildcards, an appropriate station naming plan must
be in place.
Self call – call using the station's own address, generally used for test purposes.
Bidirectional call – request for updating the LQA score with another station or
Sounding call – used to build a link quality database. This database stores
ongoing information on the current quality of the various channels programmed
for use by your radio.
All types of calls, except for sounding calls, can also carry messages.
During ALE calls, a link is established between the stations participating in the call.
During the link state, the radio operators have various options, many of them similar
to the options available in the channel mode. For a description of the link options, see
pages 19 to 23.
The information appearing in this section updates the ALE
operating instructions presented in previous publications.
Therefore, if your radio set supports MIL-STD-188-141B, use only
the ALE operating instructions appearing in this Supplement.
MICOM 2 also supports the MultiNet feature. When this feature is
enabled, it can receive and transmit ALE calls in several different
nets (up to 20). See details on page 12.
