A value of 1 means that all cells are counted for the link N+8. A value of 0 means that all
stuff cells are counted for the link N+8.
A value of 1 enables the IMA mode for the link N+8. A value of 0 enables the non-IMA
mode for the link N+8.
A value of 1 enables the descrambling of the cell for the link N+8
When set to 1, count all USER cells for link N+8,
when cleared to 0, count Filler/Idle/Unassigned cells for link N+8.
A value of 1 means that the Unassigned and Idle cells are discarded upon reception for the
link N+8.
A value of 1 enables the discard option of the cells with wrong HEC. A value of 0 will
disables the discard option, all the cells will be written to the receive buffer.
A value of 1 signifies that the ATM Forum polynomial value (coset) is not to be added to the
HEC before the verification. A value of 0 means that the HEC is calculated and compared
(i.e., including the coset).
A value of 1 enables the correction of the cells with a wrong HEC. A value of 0 disable the
correction of the HEC.
A value of 1 means that all cells are counted for the link N. A value of 0 means that all stuff
cells are counted for the link N.
A value of 1 enables the IMA mode for this link. A value of 0 enables the non-IMA mode for
the link N.
A value of 1 enables the descrambling of the cell for the link N
When set to 1, count all USER cells for link N,
when cleared to 0, count Filler/Idle/Unassigned cells for link N.
Unused. Read 0’s.
