Cells transmitted—The number of ATM cells transmitted on the E3 since the last
user reset of this counter.
Cells dropped—The number of idle/unassigned cells encountered and dropped
on the interface.
Cells with HCS errors—The number of header check sequence (HCS) errored
cells encountered on the ATM interface.

Section Performance Monitoring (current, interval, and total)
ES—The number of errored seconds (ESs) encountered by the OC3/STM-1 section.
SES—The number of severely-errored seconds (SESs) encountered by the
OC3/STM-1 section.
SEFS—The number of severely errored framing seconds (SEFSs) encountered by
the OC3/STM-1 section.
CVS—The number of coding violations (CVs) encountered by the OC3/STM-1
section.
LOS—The number of Loss of Signal (LOS) conditions encountered by the
OC3/STM-1 section.
LOF—The number of Loss of Frame (LOF) conditions encountered by the
OC3/STM-1 section.
Line Performance Monitoring (current, interval, and total)
ES—The number of errored seconds (ESs) encountered by the OC3/STM-1 line.
SES—The number of severely-errored seconds (SESs) encountered by the
OC3/STM-1 line.
UAS—The number of unavailable seconds (UASs) encountered by the OC3/STM-1
line.
CVS—The number of coding violations (CVs) encountered by the OC3/STM-1 line.
AIS—The number of Alarm Indicator Signal (AIS) conditions encountered by the
OC3/STM-1 line.
RDI—The number of Remote Defect Indication (RDI) conditions encountered by
the OC3/STM-1 interface. Also known as FERF (Far End Receive Failure). This is the
alarm that is generated when a far end AIS or LOP defect is detected.
