T1/E1 Port/Link Statistics
This section describes the T1/E1 port/link statistics.
T1/E1 Port/Link Physical Performance Statistics
The T1 (DS1)/E1 UNI Physical Performance Monitoring screen displays the following statistics.
You can view the statistics as current, interval, or total data.
ES—The number of errored seconds (ESs) encountered by the T1/E1 interface.
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.
Rx-UUS-IMA—Near end receive unusable seconds; the number of unusable seconds at the near end interworking Rx link state machine.
Tx-UUS-IMA-FE—Far end transmit unusable seconds; the number of unusable seconds at the far end interworking Tx link state machine.
