Near Encounter Mode
GROUP | 1 | 2 | 3 | 4 |
---|---|---|---|---|
G1 | Pa1 | Pa2 | Pa3 | Eb4 |
G2 | Eb1 | Eb2 | Eb3 | Eg6 |
G3 | Pd9 | Pd10 | Pd11 | Ad3 |
G4 | Eg7 | Eg8 | Eg9 | Eb5 |
G5 | PSA3 | PSB3 | PAB12 | PAB13 |
G6 | Pa4 | Pa8 | ESA0 | ESB0 |

G9 | EAB10 | Pa5 | Pa6 | Pa7 |
G15 | Aa1 | Aa2 | Pa6 | Pa7 |
G17 | Ib | Ia | See note 1 | |
G18 | See note 2 |
NOTE 1: The Status words S3-S6 are subcommutated into words 3 and 4 by the 2 low order bits of the frame counter as follows:
(Frame Count) MOD 2 | WORD 3 | WORD 4 |
---|---|---|
00 | S5 | S5 |
01 | S1 | S3 |
10 | S6 | S6 |
11 | S2 | S4 |
NOTE 2: Group 18 is derived by subcommutating the groups listed above into the Group 18 readout using the frame counter. The frame counter is incremented at the end of each Group 18 readout sequence. The readout sequence is as follows:
FRAME COUNTER BITS 2-5 |
RATE GROUP | FRAME COUNTER BITS 2-5 |
RATE GROUP |
---|---|---|---|
0000 | 1 | 0101 | 6 |
0001 | 2 | 0110 | 7 |
0010 | 3 | 0111 | 15 |
0011 | 4 | 1000 | 9 |
0100 | 5 |
