‘0’: Remove delay
‘1’: Add delay
Bit 9:0: Indicates the amount of
delay to be added to/removed
from a Group, in cells (R). Due
to ICP deration of the cell rate,
the device will actually remove
A=R*(M/(M-1)) cells of delay.
Therefore, the requested amount
must be derated from the ideal to
account for this, R=A*((M-1)/M),
where M is the frame length (32,
64, 128, 256).
