11.2.10TSP - Transmit slot prohibit
This sentence is used to prohibit an AIS station from transmitting in the specified slots. The AIS Station
receiving this sentence should not use the next occurrence of the indicated slots. This sentence is designed to
be used to protect interrogation responses from interference from Base Station transmissions and for use with
AtoN Stations. For an AtoN Station the Unique Identifier is the AtoN Station Real MMSI.
11.2.11VER - Version
This sentence is used to provide identification and version information about a talker device. This sentence is
produced either as a reply to a query sentence. The contents of the data fields, except for the unique identifier,
should be manufactured into the talker device. The unique identifier is the AtoN Station Real MMSI. In order to
meet the 79-character requirement, a "multi-sentence message" may be needed to convey all the data fields.
Note 3 This field is used to indicate a sentence that is a status report of current settings or a configuration command
changing settings. This field should not be null.
“R’ = sentence is a query response,
“C” = sentence is a configuration command to change settings.
Note 1 The MMSI is defined in the AID sentence and is the MMSI of the Real AtoN.
Note 2 The sequential identifier provides an identification number from 0 to 99 that is sequentially assigned and is
incremented for each new TSP sentence. The count resets to 0 after 99 is used. This sequential identifier is used
to identify the Base Station’s response to this TSP-sentence when it replies with a slot prohibit status report (see
TSR-sentence).
Note 3 1 = Channel 1,
2 = Channel 2.
Note 4 This is for record keeping. It contains the hour, minute, and second of this request.
Note 5 This is the slot from which the following slot offsets are referenced.
Note 6 Slot offset of the first slot in the block of slots to be blocked from use by the Base Station.
0 indicates no prohibited slots.
Note 7 Total number of consecutive slots to be blocked from use by the Base Station. The first slot of the block is also part
of the count. Therefore, the minimum value is 1.
1-5 = number of prohibited slots.
Note 8 This field is used to control the prohibited slots. This field should not be null.
C = immediately restore for use all slots currently prohibited from use,
E = the slot prohibition expires for the slots identified in this sentence after their next occurrence,
P = prohibit the use of slots identified in this sentence. Slots are restored for use using “C” or “R”,
R = restore the use of slots identified in this sentence.
Note 9 This field is used to indicate a sentence that is a status report of current settings or a configuration command
changing settings. This field should not be null.
“R’ = sentence is a query response,
“C” = sentence is a configuration command to change settings.
