■Timeslot 1 to 7 information (Un\G1245456 to Un\1245567)
Timeslot 1 to 7 information is stored in the same order as Timeslot 0 information.
RX offset/size information
■RX offset/size information (Un\G1245696 to Un\G1246179)
The start number and the number of points of RX for each station are stored.
Address
Un\G1245696 to Un\G1245697
Un\G1245698 to Un\G1245699
Un\G1245700 to Un\G1245701


Un\G1246176 to Un\G1246177
Un\G1246178 to Un\G1246179
The buffer memory address for the offset and size of each station number can be calculated using the following formulas:
• Offset buffer memory address = 1245696 + (station No.)  4
• Size buffer memory address = 1245698 + (station No.)  4
