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.
If you want to send an ALE call to specific stations that are named in the call but are
not members of a pre-determined group, make a call through the Emergency,
Message, Phone, Selective, or Send Position call type using the Group Selective
address syntax.
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 BOB1,BOB2,BOB3,BOB4,TIM,JOHN,MIK,SUE has
five different first ALE words, that is, BOB, TIM, JOH, MIK and SUE. However, this
address will be rejected because it has a total of 13 ALE words, that is, BOB, 1, BOB,
2, BOB, 3, BOB, 4, TIM, JOH, N, MIK and SUE.
If the length of the self address of the
calling station is...
The length of the address at the called
station can be...
