2110 SSB Transceiver Reference Manual 161
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, and Send Position call types using the Group Selective address syntax
(see page 167, Emergency call, page 168, Message call, page 169, Phone call, page 169,
Selective call, and page 170, Send Position call). 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 in the transceiver.
NOTE
You cannot use the Group Selective address syntax in the Get Position or
Get Status call type.
NOTE
For information on entering text in a call address see page 56, Entering
text in an ALE call address.
CAUTION
If a station detects a Group Selective call to its matching self address, it
will send a response over the air.
NOTE
When you use a Group Selective address syntax through the Selective call
type, the call icon will change to the Group Selective call icon ( ) when
the call is started.
