ALL call
NOTE: The global ALL address syntax may be used if the FED-STD-1045
ALE/CALM option or MIL-STD-188-141B ALE option is installed.
If you want to send an ALE call to all stations that are tuned to the same frequency in
an ALE/CALM HF network or scanning the channels in the scan table(s) associated
with the HF network, make a call through the Emergency, Message, Phone, Selective,
or Send Position call type using the global ALL address syntax.
The ALL call does not specifically call any stations, and does not request any
automatic responses from stations that enter the link. Stations can be configured to
accept or to ignore ALL calls.
NOTE: When you use an ALL address syntax through the Selective call type,
the call icon changes to the ALL call icon ( ) when the call is started.
The global ALL address syntax is @?@. All stations detecting the call enter an ALE
link with the calling station, if enabled to do so. The group of linking stations can be
narrowed by using a selective ALL address syntax (MIL-STD-188-141B ALE
option). In this address, the ? is replaced by an upper-case letter or number, for
example, @A@. All stations detecting the call that have this letter or number as the
last character in their self address for the ALE/CALM HF network enter the link.
If you send a selective ALL call to a group of stations, you can send another selective
ALL call to bring more stations into the link. For example, if you initially call @A@,
all stations tuned to the same frequency in an ALE/CALM HF network or scanning
the HF network with an A as the last character of their self address enter the link. If
you follow this with a call to @B@, then a further group of stations with B as the last
character of their self address also enter the link. If the called stations are already in a
link, this link is closed and a new link created with the new call.
Alternatively, you can send multiple ALL addresses together to make a call to a range
of stations, for example, @A@,@B@.
