ANY 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 ANY call uses a
special address syntax @@? that ALE
stations recognise. The ANY call requests
an automatic response from stations
detecting the call. 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. The operator
at the initiating station can use these
responses to gather information on the
status of the stations using the network.
Stations can be configured to respond to or
to ignore ANY calls.
A selective ANY call addresses a subset of
stations tuned to the same frequency in an
ALE/CALM network or scanning the
network.
A multiple selective ANY call addresses
these subsets within the one call.
automatic tuning
antenna
An antenna designed for use with
multichannel transceivers. It uses a
microcontrolled stepper motor to give
continuous tuning over the operating
frequency range of the antenna.
channel Frequencies programmed in the transceiver
to transmit and receive signals on air.
