HCSFTR[1:0]:

The HCS filter bits, HCSFTR[1:0] indicate the number of consecutive error-

free cells required, while in detection mode, before reverting back to

correction mode.

HCSFTR[1:0]

Cell Acceptance Threshold

One ATM cell with correct HCS before resumption of cell

acceptance. This cell is accepted.

Two ATM cells with correct HCS before resumption of cell

acceptance. The last cell is accepted.

Four ATM cells with correct HCS before resumption of cell

acceptance. The last cell is accepted.

Eight ATM cells with correct HCS before resumption of cell

acceptance. The last cell is accepted.

ALIGN[1:0]:

ALIGN[1:0] configures the RXCP-50 to perform cell delineation based on

byte, nibble, or bit wide search algorithms when ATM Direct Mapping is used.

Cell alignment is relative to overhead bits in the serial input data stream. The

ALIGN[1:0] bits are valid only if ATM direct mapping is used - PLCP framing

must be disabled. Recommended settings for DS3, E3, and J2 are shown.
