Making and receiving calls
Manpack Transceiver 2110 series Reference Manual 189
Group Selective address syntax
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 initiating station then completes the link
establishment with an acknowledgement sent to all stations from which it received a
response.
With Group Selective addresses, the length of the combined address can be no longer
than 12 ALE words, excluding commas. An ALE word has 3 characters. There can be no
more than 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.
NOTE
The Group Selective address syntax may be used if the MIL-STD-188-
141B ALE option is installed (2110 only).
NOTE
For information on entering text in a call address see page 77, Entering
text in an ALE call address.
CAUTION
If a station detects a Group Selective call to its matching self address, it
sends a response over the air.
NOTE For information on these call types see page 193, Call types.
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.
