MID_BITS
Enables the VCC table entry. If disabled, the cell is discarded.
When VC_EN is a logic high, configure channel to process specific AAL as listed below; otherwise,
when VC_EN is a logic low, a value of 11 causes the CELL_DSC_CNT counter not to be incremented.
00 = AAL5
01 = AAL0
10 = AAL3/4
11 = Reserved
FIFO buffer Full Discard. When a logic high and RSM_CTRL1(OAM_QU_EN) is a logic low, OAM cells
are discarded when the incoming DMA FIFO buffer is almost full.
Pointer to a PM-OAM processing word. Index with reference to top of VPI Index table. Used by the
OAM cells detected on AAL3/4 channels.
Same as AAL_EN field in standard RSM VCC entry. Used by OAM cells detected on AAL3/4 channels.
Indicates the last entry in the VCC table in which time-out processing occurs.
Enable time-out process of the VCC entry. Must be set to a logic 0.
When logic high, allow a MID value of 0; otherwise, 0 is invalid.
