SES-The number of severely-errored seconds (SESs) encountered by the T1/E1 interface. SEFS-The number of severely errored framing seconds (SEFSs) encountered by the T1/E1 interface. UAS-The number of unavailable seconds (UASs) encountered by the T1/E1 interface. CSS-The number of controlled slip seconds (CSSs) encountered by the T1/E1 interface. PCV-The number of path coding violations (PCVs) encountered by the T1/E1 interface. LES-The number of line errored seconds (LESs) encountered by the T1/E1 interface. BES-The number of bursty errored seconds (BESs) encountered by the T1/E1 interface. DM-The number of degraded minutes (DM) encountered by the T1/E1 interface. LCV-The number of line coding violations (LCVs) encountered by the T1/E1 interface. T1/E1 Port/Link IMA LInk Performance Statistics The T1/E1 Link Performance Monitoring screen lists the following statistics: IV-IMA-IMA violation; the number of errored, invalid, or missing ICP cells. SES-IMA-Near end severely-errored seconds; the number of seconds with IMA violation, LOS, AIS, OOF, LCD, LIF, LODS at the near end. SES-IMA-FE-Far end severely-errored seconds; the number of seconds with IMA violation, LOS, AIS, OOF, LCD, LIF, LODS at the far end. UAS-IMA-Near end unavailable seconds; the number of unavailable seconds at the near end. UAS-IMA-FE-Far end unavailable seconds; the number of unavailable seconds at the far end. Tx-UUS-IMA-Near end transmit unusable seconds; the number of unusable seconds at the near end interworking Tx link state machine.
