0x2953 Subsequent Information Status

If all the NPDI data cannot be sent from the Excel platform to the host in one Request for Service (RFS) with Data message, the remaining data is sent in the PPL Event Indication message (component ID 0x00A7 and event ID 0x23). If the Excel platform sends the data in multiple messages, the RFS with Data and subsequent PPL event indications, the Excel platform adds this TLV to those messages. This TLV indicates the sequence number of the message and whether it is the last Request for Service with Data message in the sequence.
