RADview-SC/TDMoIP IPmux-11 Viewing Bundle Intervals Statistics 6-5
Parameter Remarks
Buffer Underflow (sec) Number of seconds in the current interval that the receive (Eth to TDM) buffer
underflowed. When a continuous underflow is caused by a loss of frame flow, a
single buffer underflow is counted. A buffer undeflow indicates that frames were
dropped because the receive buffer was in an underrun state. The buffer enters
underflow state when:
• Sequence errors occur
• Flow underrun takes place due to PDV expiration
• An overflow condition occurs
Buffer Overflow (sec) Number of seconds in the current interval that the receive (Eth to TDM) buffer
overflowed. A buffer overflow indicates that frames were dropped because the
receive buffer exceeded the maximum allowed depth.
Max. Delay Variation
(10 μsec)
Maximum size of the buffer (in 10s of μsec) in the selected interval
Note: This parameter is used for a CES E1/T1 card whose hardware version is greater
than 5.00.
Min Jitter Buffer Level
(msec)
Minimum jitter buffer level (in msec) for the current interval
Max Jitter Buffer Level
(msec)
Maximum jitter buffer level (in msec) for the current interval
6.5 Viewing Bundle Intervals Statistics
RADview can display Intervals Statistics, information and graphs that aggregate the
statistics over 15 minute intervals. The Bundle Intervals Statistics command
displays intervals statistics for the selected bundle connection, in both table and
graph formats. This information is useful for assessing quality of service, for
network troubleshooting and planning purposes.
To view a list of statistics from previous intervals:
1. Select Statistics > Bundle Connection Statistics...
The Bundle Statistics dialog box appears (
Figure 6-2).
2. Select the bundle for which you wish to display the statistics.
3. Click <Bundle Intervals Statistics…>.
The Bundle Intervals Statistics dialog box appears.
