8x+2y...

just for completeness and so i don't appear completely invested in the method i developed to understand dscp and the corresponding af decimal values (even though i am)

here it is...


af31

8 x 3 + 2 x 1 = 26

af22

8 x 2 + 2 x 2 = 20

simply multiply the first af digit by 8 and add the second digit multiplied by 2...

or my way...

cs 0                                   0

cs1                                    8
  af11                                10
  af12                                12
  af13                                14
    
   

cs2                                    16

  af21                                18
  af22                                20
  af23                                22

so what's the decimal value of cs3? right...

my way is better... based on the cs values you can map the whole thing out on paper in 30 seconds...
