AllCall Addresses

An AllCall is a general broadcast that does not request responses and does not designate any specific

addressee: a call with this address is accepted by any station, which then stops scanning and listens to

the call. The most common use of AllCalls is in cases of distress: when in distress, it is more likely to

want to make any available connection in the minimum period of time than to issue a call to an

individual or to a select group.

The global AllCall address is @?@. As a variation, the calling station can also use selective AllCall.

Basically, the selective AllCall address is identical in function to the global AllCall, except that it

specifies the last single character of the addresses of the desired su/jointfilesconvert/270802/bgroup of receiving stations (that is,

it replaces the ? with an alphanumeric – see more details in Table 1). Any station whose address

matches the pattern stops scanning and listens.

The operator can always initiate an outgoing (transmit) AllCall, but the MICOM-3 can be programmed

to accept or ignore incoming (receive) AllCalls.

When a radio issues an AllCall, all the stations that are capable of receiving calls receive the AllCall.

In the scan mode, if the MICOM-3 station is set to receive AllCalls, it stops scanning when an AllCall

is received. If an AllCall channel has been defined, then outgoing AllCalls are performed on that

channel. If no AllCall channel has been defined, the call is performed on the first scanned channel of

the net. In the Channel mode, outgoing AllCalls are performed on the currently active channel.

Note

You can transmit an AllCall by pressing the ESC button for a few seconds.

AnyCalls

An AnyCall is a general broadcast similar to AllCall with the difference that it requests responses,

without designating any specific addressee(s). Therefore, an ALE station may use the AnyCall to

generate responses from essentially unspecified stations, and thus it can identify new stations and

connectivities.

The global AnyCall address is @@?. As a variation, the calling station can also use selective AnyCall,

which is identical in function to the global AnyCall, except that it specifies the last single character of

1 2 ... 53 54 55 56 57 58 59 60 61 62 63 ... 163 164
