3-12.3.4.10 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 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 Appendix C, which present details on ALE addressing
(including the use of wildcards in addresses).
NOTE
Before starting, you may want to select a different net to use: see
instructions on page 3-36.
When MultiNet is enabled, you will be prompted for a net number as
soon as you press CALL to start a call.
To transmit a wildcard call:
1. Press CALL. The radio displays the last called address.
If you see the address you want (that is, you want to repeat the last
wildcard call), skip directly to Step 11 below, otherwise continue as
explained below.
