This sentence is used to both enter and obtain channel management
information. When sent to an AIS unit, the ACA-sentence provides
regional information that the unit stores and uses to manage the
internal VHF radio. When sent from an AIS unit, the ACA-sentence
provides the current channel management information retained by the
AIS unit. The information contained in this sentence is similar to the
information contained in an ITU-R M.1371 message 22. The
information contained in this sentence directly relates to the
"Initialisation Phase" and "Dual Channel operation and Channel
management" of the AIS unit as described in ITU-R M.1371.
NOTE 1 This is used to bind the contents of the ACA and ACS sentences
together. If provided by the AIS, the ACS sentence shall immediately
follow the related ACA sentence, and both sentences shall contain the
same sequence number. The AIS generating ACA and ACS sentences
shall increment the sequence number by one each time an ACA/ACS
pair is created. After "9" is used, the sequence numbering process
shall begin again from "0". If the sequence numbers do not match, the
information contained in an ACS sentence is not related to the
information in an ACA sentence. The ACS sentence may be used to
respond to an "ACA Query-sentence" (See IEC 61162-1, § 5.3.2.).
The AIS shall respond by providing ACA/ACS pairs for each of the
stored regional operating settings. At any given time, the maximum
number of pairs is eight. When an ACS sentence is not sent following
an ACA sentence, the sequence number may be null.
NOTE 2 Value of 1 nautical mile to a value of 8 nautical miles (with a
resolution of 1 nautical mile)
NOTE 3 VHF channel number, see ITU-R M.1084, Annex 4
