7. When ready, press SEND to start transmitting. The display alternates between your self-address
and the channel used for the call is sent. If you did not select a specific channel, the channel
number changes as the radio sends the call on each channel assigned to the selected net.
After all the channels have been used, the call automatically stops.
You can press STOP at any time to end the call sooner.
2-12.3.4.12 Bidirectional Handshake
The bidirectional handshake is used to exchange LQA scores with other stations without establishing a
link.
NOTE
The Micom-Z 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-Z 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).
NOTE
Before starting, you may want to select a different net to use: see
instructions on page 2-35.
To execute a bidirectional handshake with an individual station:
1. Press LQA to enter the LQA menu.
2. Press BIDR. The last called address is displayed. If this is the address you want, skip directly to
Step 6 below.
3. To select a different address, use the UP/DOWN keys to scroll to the required address in the
directory, and then press ENTER to confirm your selection.
or
If the station you want to add to the group is not in the directory:
Enter the new station using the keypad. If you make a mistake, scroll to the desired position
using < −
< − < −
< − and/or − − >
− − >− − >
− − >, or clear (CLR) the whole entry and start again.
When ready, press SAVE to store the new station in the directory.
4. Press PAGE if you wish to attach a message to the bidirectional handshake process. After
confirming the message, exclamation mark precedes the name of the called station, indicating
that a message has been attached.
5. Press CHAN if you wish to execute a bidirectional handshake process on a specific channel.
6. Press SEND or ENTER in order to initiate the bidirectional handshake process. During this
process, you will see TO alternating with the number of the channel on which the set up request
is being sent.
