Fragmented Indicates the number of packets that arrived to the IP
card fragmented (i.e., a single packet broken by the
network into multiple packets). This value can indicate
the delay and reordering of fragmented packets that
require additional processing, but is not considered a
fault.
The Fragmented information is displayed with the
following details:
• Accumulated N - total number of packets that
were fragmented since the channel opened.
• Accumulated % - percentage of fragmented
packets out of the total number of packets
transmitted since the channel opened.
• Interval N - number of fragmented packets
received in the last RTP report interval (default
interval is 5 minutes).
• Interval % - percentage of fragmented packets out
of the total number of packets transmitted in the
last RTP report interval (default interval is 5
minutes).
• Peak - the highest number of fragmented packets
in a report interval from the beginning of the
channel's life span.

Jitter
Mechanism
The values this information provides may indicate
problems with the network which can affect the audio
and video quality.
Jitter Buffer Size The maximum permitted delay in milliseconds in the
expected arrival time (buffer size) determining whether
packets are processed or considered as lost.
For example, if the jitter buffer size is 15-milliseconds
and a packet from an endpoint arrives with a
12-millisecond delay, the packet is processed.
• N - the current jitter buffer size.
• Peak - the highest jitter buffer size from the
beginning of the channel's life span.
