Table 1. Use of “@” Stuffing Symbol (Cont.)

Pattern

Interpretation

 

 

@A @ “Selective AllCall” global address: each station with the same last character “A” stop scanning and listen (unless this function is inhibited

@@ ? “AnyCall” global address (see also Table 2): all the stations stop scanning and respond in randomly selected timeslots (unless this function is inhibited)

@@ A “Selective AnyCall” address: each station with same last character(s) “A” (or

@ B@

“B”) stops scanning and responds in a randomly selected timeslot (unless this

function is inhibited), using its own address

(option)

 

@A B “Double selective AnyCall” address: each station with same last characters “AB”

@ C D

(or “CD”) stops scanning and responds in a randomly selected timeslot (unless

this function is inhibited), using its own address

(option)

 

@@ @ “Null” address; all the stations ignore this address. The null address intended for use in test and maintenance, or to create an extra “buffer” timeslot

Net Addresses

The purpose of a net call is to rapidly and efficiently establish contact with multiple prearranged (net) stations. This is achieved by the use of a single net address.

The net address is actually an additional address assigned in common to all the stations that are members of a specific net. Its address structure is identical to that used for individual station addresses (basic or extended, with or without stuffing, as necessary).

When defining a net, each member station is automatically assigned a timeslot: by having each station answer a call request in a different timeslot, collisions are avoided.

Group Addresses

The purpose of a group call is to rapidly and efficiently establish contact with multiple non-prearranged (group) stations.

To make a group call, a calling ALE station uses a sequence of the actual individual station addresses of the called stations.

Special Addressing Modes – Use of Wildcards

A “wildcard” is a special character,“?”, that a calling station can use to address multiple stations with a single call address. The following rules apply:

•The total length of a calling address that includes wildcard(s) must be equal to that of the called station addresses.
