CBR Performance Monitoring Statistics

The CBR Performance Monitoring screens display the following statistics for the
CBR T1-DSX/E1 ports:
ES — The number of errored seconds (ESs) encountered by the CBR T1-DSX/E1
interface
SES — The number of severely-errored seconds (SESs) encountered by the CBR
T1-DSX/E1 interface
SEFS — The number of severely errored framing seconds (SEFSs) encountered by
the CBR T1-DSX/E1 interface
UAS — The number of unavailable seconds (UASs) encountered by the CBR
T1-DSX/E1 interface
CSS — The number of controlled slip seconds (CSSs) encountered by the CBR
T1-DSX/E1 interface
PCV — The number of path coding violations (PCVs) encountered by the CBR
T1-DSX/E1 interface
LES — The number of line errored seconds (LESs) encountered by the CBR
T1-DSX/E1 interface
BES — The number of bursty errored seconds (BESs) encountered by the CBR
T1-DSX/E1 interface
DM — The number of degraded minutes (DMs) encountered by the CBR
T1-DSX/E1 interface
LCV — The number of line coding violations (LCVs) encountered by the CBR
T1-DSX/E1 interface

CBR ATM Statistics

CBR ATM cell statistics are cell counts since the last counter reset. On the CBR
ATM Statistics screen, you can reset the counter by entering . ATM statistics are
c
displayed as a list rather than a table. The CBR T1-DSX and CBR E1 ATM Statistics
screens display the following statistics:
CBR virtual circuits must be present in the database in order to view these
statistics.
Total Cells Received — The total number of cells received over the virtual circuit.
Total Cells Transmitted — The total number of cells transmitted over the virtual
circuit.
Total Cell Pointer Errors — The number of cells dropped due to structure pointer
mismatches.
Total Cells Lost — The difference between the number of cells transmitted and
the number of cells received.
Total Number of Buffer Underflows — The number of buffer underflows over
the virtual circuit.
Total Number of Buffer Overflows — The number of buffer overflows over the
virtual circuit.
Total out of Sequence Errors — The number of cells received with
out-of-sequence number mismatch.
