Transmitting Wildcard Calls
Wildcard calls, that is, calls in which the destination address includes the wildcard
character ?, let you to simultaneously address multiple stations with a single address:
• Any station receiving an address with wildcards stops scanning and checks the
address length: if the number of characters in the received address is different
from the number of characters in its own self-address, the station ignores the
call.
• If the received address matches the length, a receiving station checks the
significant positions in the received address against its own. For example, the
stations JOHN and JOIN will both accept a call with the address JO?N.
• Each station accepting the call answers the calling station in a pseudo-random
slot.
MICOM-2 will wait for responses for a certain time before entering the link state
with all the stations that responded within this interval (the maximum number of
stations that are accepted in a wildcard call is 16). Therefore, with the wildcard
option, the link set up process takes more time, because the radio waits longer to get
responses (it cannot “guess” the number of stations that will answer).
Before continuing, you may wish to review pages 7 to 11, which present details on
ALE addressing (including the use of wildcards in addresses).
