Motorola MICOM-2ES/2RS/2TS ALE - Manual (Page 23)

New ALE Features
• A receiving station will accept a wildcard character as a substitute for the
alphanumeric character in its own address that occupies the same position. This
means that the wildcard character is a substitute for any of 36 characters and
digits (A to Z, 0 to 9) in the Basic 38 character subset.
• Multiple wildcard characters can be used in different positions of the same
address (basic or extended).
See Table 2 for examples of patterns using the “?” wildcard symbol.
Table 2. Use of “?” Wildcard Symbol
Pattern Interpretation
A B C “Standard” 3-character address, shown here for reference. All the characters in
this word must be evaluated
A B ?
A ? C
? B C
“Standard” “wild-1” address word. Indicates that only the positions occupied by
other characters (“A” and “B”) need be evaluated: the position occupied by the
“?” symbol can be ignored (ignored in this context means that any valid character
is accepted)
A ? ?
? B ?
? ? C
“Standard” “wild-2” address word. Indicates that only the position occupied by an
character (“A”, “B” or “C”) need be evaluated: the positions occupied by the “?”
symbols can be ignored
? ? ? “Standard” “wild-3” address word. Indicates that all of the three positions in this
word can be ignored
A B @ “Stuff-1” reduced address field, shown here for reference. Only the first two
characters in this word must be evaluated
A ? @
? B @
“Wild-1” “stuff-1” address. Only the character “A” or “B” in this word must be
evaluated
? ? @ “Wild-2” “stuff-2” address. Only the character “A” or “B” in this word must be
evaluated
A @ @ “Stuff-2” reduced address field, shown here for reference. Only the first character
in this word must be evaluated
? @ @ “Wild-1” “stuff-2” address. Only the first character in this word must be
evaluated, and is ignored
@ A B “Double selective AnyCall” address word, shown here for reference: only the last
two characters in this word must be evaluated
