Response Time
The next field is the response time. This is the amount of time in
TWs that the unit will wait for a response, before going on the next
channel. Default time of 30TW is adequate for most radios.
SPECIAL ADDRESS TYPES
There are three additional address types called “allcall”, “anycall”, and
“wildcard”. These types are programmable under the SINGLE type.
These call types require some ALE expertise for proper utilization.
All Call Allows a message or call to be broadcast to multiple
stations without requiring a response from them.
Any Call Allows a call to multiple stations without having to know
their entire address.
Wild Card Used to call multiple stations. The called stations will
accept the wild card character as a match for the
character in it’s address that occupies that same position
in the address.
