Formula for determining the frame delay:
Fdel
Cdel
TSout = Time-slot number out
TSin
TSdur = Time-slot duration = 32
With the above you should be able to calculate the frame delays for all switching possibilities.

Applications
= Frame delay (e.g. Fdel = 1.5 means 1 frame delay and
= Component delay
= Time-slot number in
C del – (TS out – TS in) TS dur + 1024
Fdel = 0.8 means 0 frame delay)
