Using Automatic Link Establishment (ALE)
77
Using the Inlink Function
When the inlink function is enabled (see instructions in the ALE Options
Configuration section starting on page 91), the stations participating in a
call are automatically notified by a DISC message whenever another
participant leaves (disconnects from) the call.

The link is then automatically disconnected when only one station is left (that is, after all the other
participants disconnected).
The inlink function is available in any type of call that involves the setting up of a link using
bidirectional handshaking. Therefore, you can use it in individual calls, group calls, net calls, etc., but
not in AllCalls and self calls.
Notes
For the inlink function to operate correctly, it must be enabled on all the stations.
Do not enable the inlink function when communicating with a radio that does not
support the full ALE capabilities in accordance with MIL-STD-188-141B.
To avoid disconnecting the link too soon as a result of inactivity (that is,
after the PTT time-out interval (PTOT) programmed under the ALE Options
Configuration section), each participant can request other stations to wait
beyond the PTOT interval (up to 10 minutes more) before automatic
disconnection occurs.

This option (TOT – time-out interval) is displayed over the F4 key after the link is set up: to send a
request for the other stations to wait more time, press the TOT (F4) key.
Transmitting ALE Calls in the Channel Mode
The ALE option is available in both the ALE and Channel modes and therefore, the radio can also
answer ALE calls.
The transmission process is similar for both operating modes, with the following differences:
In the Channel mode, every call is initiated on the currently selected channel.
The LQA function is not available in the Channel mode: sounding and bidirectional calls can
only be initiated in the ALE mode.
When the radio is in the Channel mode, it uses the parameters programmed for net 1.
Important
If net 1 is not programmed, there is no ALE functionality in the Channel
mode, even if the ALE option is turned on.
