Any Calls
An Any Call is a linked call which can be answered by up to 16 stations. The called stations
pick out a random time slot for their response.
Whether a station actually sets up a link when receiving an Any Call is up to configuration.
LQA Calls
An LQA Call is a call directed to a particular station. As soon as the link has been established,
the LQA data of the two stations are exchanged.
Sound Calls
A Sound Call is a call which is not directed to any particular station. All stations listening in
on the calling channel automatically carry out a channel analysis.

ALE-2G Missions and Database
The operator plans ALE-2G networks using the R&S Mission Planner. The R&S Mission
Planner generates the ALE-2G database for each radio in the network and the operator has
to load the data into each participating radio in the network. The ALE-2G network shall con-
sist of at least 2 radios and up to 15 radios.

User Unique Functions
The User Unique Function (UUF) is used to control the link mode (i.e. traffic type). Two types
of link mode are defined. These types are manufacturer specific.
•
Analog voice / FF
•
Internal modem
The default link mode is analog voice / FF, i.e. when no UUF is used, the link mode is analog
voice. The radio has the capability to send and process the UUF words defined also for other
Rohde & Schwarz radios supporting UUF.
In the call phase, a UUF command word is transmitted which depends on the link mode cur-
rently set on the radio.
