Field Name
COM free buffer queue pool number.
BOM free buffer queue pool number.
Number of AAL3/4 cells received with CRC10 error.
Number of AAL3/4 cells received that did not have an active MID as determined by the MID_BITS
and MID0 fields.
Number of AAL3/4 cells received that had an unexpected LI value.
Number of AAL3/4 cells received that had an unexpected SN value.
Number of unexpected AAL3/4 BOM or SSM cells received.
Number of unexpected AAL3/4 EOM cells received.
Channel index of corresponding segmentation channel. Used by ER and PM-OAM processing.
Index into ER_SHIFT table for implicit congestion ER reduction. Base table address is given by
ER_SHIFT_B register field.
When ABR_VPC is a logic low, RX_COUNTER is the firewall mode credit counter. When ABR_VPC is
a logic high, VPC_INDEX is used to control a VPC group. See ABR_VPC for description of this field.
Enable destination ACR/ER change notification processing.
Logic high results in CR change notification; logic low results in ER change notification.
Destination ACR/ER change has been triggered. Initialize to logic low.
Indicates direction of destination ACR/ER trigger, logic high for HI, logic low for LO.
Congestion Identification number.
Enables explicit congestion ER reduction mechanism.
Enables implicit congestion ER reduction mechanism; not valid when EN_EXP_CNG is logic high.
Set CI to logic high in turned-around BCK RM cells.
Set NI to logic high in turned-around BCK RM cells.
Set ER to minimum of this value and in coming FWD RM ER value in turned-around BCK RM cells
when EN_EXP_CNG is logic high.
Destination ACR/ER upper threshold, exponent portion.
Destination ACR/ER upper threshold, mantissa portion.
Destination ACR/ER lower threshold, exponent portion.
Destination ACR/ER lower threshold, mantissa portion.
