Group Selective call
NOTE: This address syntax may be used if the MIL-STD-188-141B ALE
option is installed.
CAUTION: If a station detects a Group Selective call to its matching self address,
it sends a response over the air.
A Group Selective call may be made to specific stations that are tuned to or scanning
the same frequency in an ALE/CALM HF network. The Group Selective address
syntax may be used with the Emergency, Message, Phone, Selective, or Send Position
call type.
The Group Selective call requests an automatic response from stations that detect the
call and whose self addresses match one of those in the call. These responses are sent
in reverse order from that provided in the call. The calling station then completes the
link establishment with an acknowledgement sent to all stations from which it
received a response.
NOTE: When you use a Group Selective address syntax through the Selective
call type, the call icon changes to the Group Selective call icon ( )
when the call is started.
With Group Selective addresses, the length of the combined address can have up to
12 ALE words, excluding commas. An ALE word has 3 characters. There can be up
to five different first ALE words in the combined address.
For example, an address of BOB,BOB2,BOB3,BOB4,TIM,JOHN,MIK,SUE has
five different first ALE words, that is, BOB, TIM, JOH, MIK and SUE. This address
has a total of 12 ALE words, that is, BOB, BOB, 2, BOB, 3, BOB, 4, TIM, JOH, N,
MIK and SUE.
