What It Indicates

Rx PDUs	The number of received AAL5 CPCS PDUs passed to a higher
	layer.
Tx Octets	The number of AAL5 CPCS octets (bytes) passed to the lower
	layer for transmission.
Rx Octets	The number of received AAL5 CPCS octets (bytes) passed to
	a higher layer.
Errored Tx PDUs	The number of AAL5 CPCS PDUs that could not be
	transmitted due to errors.
Errored Rx PDUs	The number of received AAL5 CPCS PDUs that contained
	errors.
Discarded Tx PDUs	The number of AAL5 CPCS PDUs received for transmission
	that were discarded.
Discarded Rx PDUs	The number of received AAL5 CPCS PDUs discarded.
TC Sublayer
Total Tx Cells	The number of cells transmitted.
Total Rx Cells	The number of cells received.
Total Rx Cells	The number of received cells dropped due to errors.
Dropped
Rx HEC Errors	The number of cells received whose HEC fields were in error.
Unknown Rx Cells	The number of received cells discarded during cell header
