New ALE Features

Note

In the following sections, “A,” “B,” “C” or “D” indicates any
alphanumeric character other than “@” or “?”.

MICOM 2 has the capacity to store and use 100 addresses of up to 15 characters
each. MICOM 2 will reject addresses longer than 15 characters, and will notify you
with an UFA WRONG message.

Address and Call Types

ALE stations, including the MICOM 2, have the capability and flexibility to link with
one or many prearranged or as-needed single or multiple stations. There are three
general addressing methods:

• Individual station addressing
• Multiple stations addressing, for example, net and group
• Special addressing modes, for example, AllCall, AnyCall, etc.

The following sections explain the addressing modes and how they can be used for
various purposes.

Individual Station Address

The individual station address may contain 1, 2, 3, 4, or 5 words. To enable using
addresses that are not an integer multiple of 3 characters (for example, an address
consisting of 1, 2, 7, 8, 10, …, etc. characters), stuffing can be used: with stuffing,
the last address word includes one or two stuffing symbols in the last position(s) (see
the “stuff-1” and “stuff-2” patterns in Table 1).
The wildcard symbol cannot be included in an individual station address, nor in a call
request to an individual station.

Table 1. Use of “@” Stuffing Symbol

Pattern Interpretation

A B C

“Standard” 3-character address word, shown here for reference. Only the station
with this address stops scanning and responds

A B @ “Stuff-1” reduced address field, used to add characters “A, B” at the end of the

address

A @ @

“Stuff-2” reduced address field, used to add character “A” at the end of
the address

@ ? @

“AllCall” global address (see also Table 2): all the stations stop and listen (unless
this function is inhibited)
