Wildcard call An ALE address syntax used to broadcast to
any station that is tuned to the same
frequency in an ALE/CALM network or
scanning the network. The Wildcard address
syntax, which ALE stations recognise, uses
the wildcard character ? as a placeholder for
characters within a self address of a
receiving station. Stations that detect the
call and whose self address matches the
pattern in the wildcard address will send a
response to the initiating station. These
responses are returned in any slot position
(collisions may occur). The initiating station
then completes the link establishment with
an acknowledgement sent to all stations
from which it received a response.
A multiple Wildcard call addresses
matching subsets within the one call.
