BYTE

FIELD

VALUE

DESCRIPTION

EXTRACT_STATUS_CFM

0x99

Extract Status Confirm header

location

0x00 – location 0

0x01 – location 1

Since SDEC can extract two services

simultaneously, system controller

assigns an extraction location.

Channel number

1-255

Extracted channel number

SID

1-255

SID of location 0 extraction.

Extraction status

0x00 – Not initiated

0x01 – In progress

0x02 - Ok

0x03 – Incorrect parameter in

command.

bit 6 – Service Detect

0x40 – SID_UNDETECTED

0x00 – SID_DETECTED

bit 5 – SC Type Detect

0x20 – SCT_UNDETECTED

0x00 – SCT_DETECTED

bit 4 – Authorization

0x10 – AUTH_MISSING

0x00 – AUTH_OK

bit 3 – Reserved

bit 2 – RAT Block

0x04 – RAT_BLOCKED

0x00 – RAT_UNBLOCKED

bit 1 – RAT Low

0x02 – RAT_LOW

0x00 – RAT_OK

b0 – TOD Rollback

0x01 – TOD_ROLLBACK

0x00 – TOD_OK

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
