NOTE 1 The length of an ITU-R M.1371 message may be long and may require the use of
multiple sentences. The first field specifies the total number of sentences used for
a message, minimum value 1. The second field identifies the order of this

0 to 9 that is sequentially assigned and is incremented for each new multi-
ssage. This allows for the possibility that other sentences
might be interleaved with the message sentences that, taken collectively, contain a

sentence in the message, minimum value 1. These cannot be null fields.
The Sequential message identifier provides a message identificatio
sentence message. The count resets to 0 after 9 is used. For a message requiring
multiple sentences, each sentence of the message contains the same sequential
message identification number. It is used to identify the sentences containing
portions of the same me
single message. This field shall be a null field when a message fits into one
sentence.
This is the channel used to broadcast the AIS message. The AIS channel fie
to either "A" or "B", indicates that the message was broadcast. If the message is
not broadcast, the "AIS Channel" field shall be null. The VHF channel numbers
for channels "A" and "B" are obtained by using an ACA-sentence "query" of the
AIS.
The maximum string length of encapsulation is limited such that the total number
of sentence characters does n
characters for a message using a single sentence.
To encapsulate, the number of binary bits must be a multiple of six. If it is not,
one to five "fill bits" are added. This parameter indicates the number of bits
were added to the last 6-bit coded character. This value shall be set to zero when
no "fill bits" have been added. This cannot be a null field.
