Bidirectional Handshake

The bidirectional handshake is used to exchange LQA scores with other stations
without establishing a link.

Note

The MICOM-2 can also be programmed to automatically initiate
the call to the station after finishing the bidirectional handshake
(using the BDLK parameter reached under the ALE programming
options).

A bidirectional handshake can be carried out with a single station or with all stations
in the net. It can be carried out either on a single channel, or on all the net channels.
When required, a message can also be added to the procedure.
After a bidirectional handshake with a single station, the LQA matrices of both
radios are updated. The operator can then initiate a call to that station and obtain the
best channel automatically.
When the bidirectional handshake procedure is performed with a net, all the stations
in the net update their LQA tables.
MICOM-2 will wait for responses for a certain time before entering the link state
with all the stations that responded within this interval (the maximum number of
stations that are accepted in a bidirectional handshake is 16).
