If you select [2] VC Statistics, an additional screen appears from which you must
select the virtual circuit for which you want to view statistics.

Voice Compression Module Performance Monitoring Statistics

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

Voice Compression Module VC Statistics

Voice compression module VC statistics are frame and byte counts since the last
counter reset. On the VCM VC Statistics window, you can reset the counter by
entering . VC statistics are displayed as a list rather than a table. The VCM
c
T1-DSX and VCM E1 VC Statistics screens display the following statistics:
Received Frames — The total number of frames received over the virtual circuit
Transmitted Frames — The total number of frames transmitted over the virtual
circuit
AAL5 Errors — The total number of invalid frames (received with good FCS but
could not be processed due to wrong content) received over the virtual circuit
Discarded Congested Frames — The total number of frames received over the
virtual circuit that were discarded due to congestion (not transmitted due to link
congestion)
