excessive congestion on the network interface. If the congestion is not corrected the
quality of voice calls will be affected. The topology of the network attached to the
network interface with the errors should be examined and modified to better
segment and isolate network traffic.
Viewing Advanced System Information
To view advanced system information for the 4300T proceed to the System
Information page as follows:
A. Select System.
B. Select System Overview.
C. Select System Information.
The following system information is displayed:
System Uptime
System Uptime displays the current time, the
amount of time elapsed since the last system
reboot, and the system load averages for the past
1, 5, and 15 minutes. Uptime can help trace
when a power outage may have interrupted
service. Load averages that remain greater than
2 indicate excessive system loading. Partitioning
voice traffic using a second system may be
required.
Process Information
Displays the active processes in the 4300T.
Memory Usage
Displays detailed memory allocation information
that may be of use to technical support.
System Logging Messages
Displays information logged during system boot and normal operation. Logging
messages may indicate unauthorized attempts to access the 4300T, process restart
messages, and excessive resource utilization messages.
Passive Voice Call Monitoring
The 4300T monitors live voice calls and performs objective speech quality
assessment. This information enables the network operator to assess voice quality
for the purposes of SLA tracking or problem isolation. Mean Opinion Score (MOS)
results for RTP streams in both directions of a VoIP call are calculated at call
completion. This information along with the IP addresses of the VoIP endpoints
supporting the call are logged locally and optionally sent to an external syslog server
(see Enable Remote System Logging for instructions on enabling logging to a
remote syslog server). Additionally the 4300T will generate a real-time message for
any MOS values calculated less than 2.5 (considered poor quality) during an active
call.
