3.1.5.1.2 DVC Data (DYNVC_DATA)
The DYNVC_DATA (section 2.2.3.2) PDU is used to send data when the total length of the PDU message plus the PDU header exceeds 1,600 bytes or the length of the message data being sent is less than 1,590 bytes. In the case where the total length of the PDU message plus the PDU header exceeds 1,600 bytes, the DYNVC_DATA_FIRST (section 2.2.3.1) PDU is sent as the first data PDU, followed by DYNVC_DATA (section 2.2.3.2) PDUs until all the data has been sent.
To send compressed data, the DYNVC_DATA_COMPRESSED (section 2.2.3.4) PDU can be used in place of the DYNVC_DATA PDU, as specified in section 3.1.5.1.4.
