; DTMF Reverse Twist and Normal Twist is the difference in power between the row and column energies.
;
; Normal Twist is where the row energy is greater than the column energy.
; Reverse Twist is where the column energy is greater.
;
; Power level difference between frequencies for different Administrations/RPOAs
