Figure 8.2.13-1: Volume Threshold
The following flags are coded within Octet 5:
– Bit 1 – TOVOL: If this bit is set to "1", then the Total Volume field shall be present, otherwise the Total Volume field shall not be present.
– Bit 2 – ULVOL: If this bit is set to "1", then the Uplink Volume field shall be present, otherwise the Uplink Volume field shall not be present.
– Bit 3 – DLVOL: If this bit is set to "1", then the Downlink Volume field shall be present, otherwise the Downlink Volume field shall not be present.
– Bit 4 to 8: Spare, for future use and set to "0".
At least one bit shall be set to "1". Several bits may be set to "1".
The Total Volume, Uplink Volume and Downlink Volume fields shall be encoded as an Unsigned64 binary integer value. They shall contain the total, uplink or downlink number of octets respectively.
