MODULES (E1/PRA-1) > PERFORMANCE CURRENT
Write security: 5; Read security: 5
The performance fields (either current, 15-minute total, or 24-hour total) provide status on key
performance measures as specified in G.821 and RFC 1406 for the E1/PRA port as follows:
PRT Displays the port number
CLR Clears performance information for the selected port
ES Errored Second (ES) is a second with one or more error events OR one or more Out
Of Frame events OR one or more Controlled Slips
BES Bursty Errored Second (BES) is a second with more than one, but less than 320 error
events
SES Severely Errored Second (SES) is a second with 320 or more error events OR one or
more Out Of Frame events
UAS Unavailable Second is a second in which the E1 was not available for use (due to
outage, alarms, etc.).
CSS Controlled Slip Second
SEFS Severely Errored Frame Second is a second that contains four consecutive errored
framing patterns
DM Degraded Minutes is the number of minutes with a bit error rate of 10 -6 or greater
LCV Line Code Violation indicates a mismatch in line coding somewhere in the network
and is determined by receiving an invalid line violation (bipolar violation).
PCV Path Code Violation is a received error in the frame synchronization bit (for non
CRC framing) or a CRC error (CRC framing).
LES Line Errored Second is a second in which an error was received on the T1.
LOFC Loss of Frame Count is a count of seconds in which a valid framing pattern could not
be obtained
MODULES ((E1/PRA-1) > PERFORMANCE 15MIN
Write security: 5; Read security: 5
Stores the performance data for the previous 15-minute window. Refer to Modules (E1/PRA-1) >
Performance Current for a detailed description of these fields.
MODULES (E1/PRA-1) > PERFORMANCE 24HR
Write security: 5; Read security: 5
Stores the performance data for the previous 24-hour window. Refer to Modules (E1/PRA-1) >
Performance Current for a detailed description of these fields.
MODULES (E1/PRA-1) > CONFIGURATION
Write security: 5; Read security: 5
All of the following configurable parameters apply whether the port is connected to a Primary Rate Access
circuit or a channelized E1 circuit.
