signalStatusBlock OBJECT-TYPE
SYNTAX OerString
ACCESS read-write
STATUS mandatory
DESCRIPTION
"<Definition> An OER encoded string of the signalStatusTable structure as defined below. This object is used for uploading configuration data from the ASC in a bandwidth efficient manner.
The following data is repeated for each channel. OPTIONAL fields shall be present only if there are changes in the data values and if the data is supported by the implementation. The OPTIONAL fields shall be omitted for any data that has not changed from a previously transmitted object or not supported by the implementation.
signalStatus ::= SEQUENCE {
ascCurrentTick.0, -- @NTCIP1202-v03, Bytes 1 & 2
channelData SEQUENCE OF channelSignalData OPTIONAL}
channelSignalData ::= SEQUENCE {
channelNumber.x -- 1 BYTE @NTCIP1202-v03
signalStatusBitMask.x -- 1 BYTE
signalState.x OPTIONAL, -- 1 BYTE @NTCIP1202-v03
signalStateMinEndTick.x OPTIONAL, -- 2 BYTES @NTCIP1202-v03
signalStateMaxEndTick.x OPTIONAL, -- 2 BYTES @NTCIP1202-v03
signalStateLikelyEndTick.x OPTIONAL, -- 2 BYTES @NTCIP1202-v03
signalStateTickConfidence.x OPTIONAL, -- 1 BYTE @NTCIP1202-v03
signalNextTick.x OPTIONAL -- 2 BYTES @NTCIP1202-v03}
where:
signalStatusBitMask is a bit mask (INTEGER (0..255)) defining the data that follows in the OerString. When a bit=1, the data is included in the OerString. If a bit=0, the corresponding data is omitted and not in the OER string.
Bit 7: Reserved
Bit 6: Reserved
Bit 5: signalNextTick - reference tick to next green state data is present. Values are 0..36001. 36001 means could not calculate or undefined.
Bit 4: signalStateTickConfidence data for this channel is present (1 byte).
Bit 3: signalStateLikelyEndTick data for this channel is present (2 bytes). Values are 0..36001. 36001 means could not calculate or undefined.
Bit 2: signalStateMaxEndTick data for this channel is present (2 bytes). Values are 0..36001. 36001 means could not calculate or undefined.
Bit 1: signalStateMinEndTick data for this channel is present (2 bytes). Values are 0..36001. 36001 means could not calculate or undefined.
Bit 0: signalState data for this channel is present (1 byte).
