EXTRACT_STATUS_CFM
0x99
Extract Status Confirm header
1
location
0x00 – location 0
0x01 – location 1
Since SDEC can extract two services
simultaneously, system controller
assigns an extraction location.
2
Channel number
1-255
Extracted channel number
3
SID
1-255
SID of location 0 extraction.
4
Extraction status
0x00 – Not initiated
0x01 – In progress
0x02 - Ok
0x03 – Incorrect parameter in
command.
5
extract_error_status
bit 7 – PC Detect

0x00 – PCID_DETECTED
bit 6 – Service Detect
0x40 – SID_UNDETECTED
0x00 – SID_DETECTED
bit 5 – SC Type Detect
0x20 – SCT_UNDETECTED
0x00 – SCT_DETECTED
bit 4 – Authorization

0x00 – TOD_OK
The bits are ordered from left to right.
The MSB is on the left and the LSB is on
the right.
b7, b6, b5, b4, b3, b2, b1, b0
6 – 8
Counter
Byte 6: LSB byte
Byte 7: Middle byte
Byte 8: MSB byte
If status=0, counter = 0
For all other status, counter is #x432ms
for actual time, counter will be running
free until a channel is selected or
initialized on the next fast extract
command
