Making and receiving calls
Manpack Transceiver 2110 series Reference Manual 191
Wildcard address syntax
If you want to send an ALE call to all stations that are tuned to the same frequency in an
ALE/CALM network or scanning the network, and receive a response, make a call
through the Emergency, Message, Phone, Selective, or Send Position call type using the
Wildcard address syntax.
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 send a response to the initiating station. These responses are returned in any slot
position (collisions may occur). For example, a call sent to EM? may be responded to by
stations in the network with a self address in the ranges EMA to EMZ and EM0 to EM9.
The initiating station then completes the link establishment with an acknowledgement
sent to all stations from which it received a response.
You can send multiple Wildcard addresses together to make a call to a range of stations,
for example, ?A,B??.
The allowable length of the self address at the called station is dependent on the length of
the self address used by the initiating station for the call.
NOTE
The Wildcard address syntax may be used if the MIL-STD-188-141B
ALE option is installed (2110 only).
NOTE
For information on entering text in a call address see page 77, Entering
text in an ALE call address.
CAUTION
If a station detects a Wildcard call to its matching self address, it sends a
response over the air.
NOTE For information on these call types see page 193, Call types.
NOTE
When you use a Wildcard address syntax through the Selective call type,
the call icon changes to the Wildcard call icon ( ) when the call is
started.
NOTE
The wildcard question marks can be in any position within the address.
The stations that respond have an address that is the same length as the
wildcard address sent from the initiating station.
If the length of the self address of the
initiating station is...
The length of the self address at the
called station can be...
1 to 3 characters 3 to 9 characters
4 to 6 characters 3 characters
