Field
Description
InOctets
Number of received octets over the interface
OutOctects
Number of transmitted octets over the interface
InErrors
Number of cells dropped due to uncorrectable HEC
errors
InUnknown
Number of received cells discarded during cell header
validation, including cells with unrecognized VPI/VCI
values, and cells with invalid cell header patterns. If
cells with undefined PTI values are discarded, they are
also counted here.
InHecErrors
Number of cells received with an ATM Cell header HEC
error.
InInvalidVpiVciErrors
Number of cells received with an unregistered VCC
address.
InPortNotEnabledErrors

enabled.
InPtiErrors
Number of cells received with an ATM header Payload
Type Indicator (PTI) error.
InIdleCells
Number of idle cells received.
InCircuitTypeErrors
Number of cells received with an illegal circuit type.
InOamRmCrcErrors
Number of OAM and RM cells received with CRC errors.
InGfcErrors
Number of cells received with a non-zero GFC.
Tab. 4: ATM AAL5 Layer Statistics over ADSL interface
Field
Description
InOctets
Number of received AAL5/AAL0 CPCS PDU octets.
OutOctets
Number of AAL5/AAL0 CPCS PDU octets transmitted.
InUcastPkts
Number of received AAL5/AAL0 CPCS PDUs passed to
a higher-layer.
OutUcastPkts
Number of AAL5/AAL0 CPCS PDUs received from a
higher-layer for transmission.
InErrors
Number of AAL5/AAL0 CPCS PDUs received that
contain an error. The types of errors counted include
CRC-32 errors, SAR timeout errors and oversized SDU
errors.
OutErrors
Number of AAL5/AAL0 CPCS PDUs that could not be
transmitted due to errors.
InDiscards
