The corresponding Bulk Dump will be sent.
In the Voice Mode, Model ID = 57H is transmitted, in the VL-
XG Model ID = Channel 4 is transmitted.
For the Address and Byte Count, refer to the supplementary
tables.
Here, the Byte Count is indicated by the “TOTAL SIZE” in
the table.
The block’s leading byte is the Bulk Dump and Dump Request’s
Address.
A “Block” is the lumped together unit which is indicated by
the “Total Size”.
The Check Sum is the value that results in a value of 0 for the
lower 7 bits when the Start Address, Byte Count, Data, plus
the Check Sum itself are added.
