Field Field description
Default bandwidth The network capacity used by the media
(both to and from channels established by the
the server) TelePresence Server to unknown
endpoints and to new pre-configured
endpoints for which a value has not been
set.
Maximum Sets the maximum payload size (in bytes)
transmitted video of the packets sent by the TelePresence
packet size Server for outgoing video streams (from
the TelePresence Server to connected
endpoints and endpoint groups).

Usage tips
When the TelePresence Server makes a
call to an endpoint, it chooses the
maximum bandwidth that is allowed to be
used for the media channels which
comprise that call. This field sets that
maximum bandwidth, and is the total
bandwidth of the audio, video, and content
channels combined. For endpoint groups,
this is the maximum bandwidth per
endpoint.
This setting can be overridden for
individual endpoints in the
settings page.
This setting can be overridden for
individual endpoints in the
settings page.
Video streams generally contain packets
of different lengths. This parameter only
sets the maximum size of a transmitted
network datagram. The Cisco
TelePresence Server optimally splits the
video stream into packets of this size or
smaller. Thus, most transmitted packets
will not reach this maximum size.
Increasing this value can cause
fragmentation of packets which impairs
performance and can cause packet loss.
Decreasing this value too much can also
impair performance.
Note: You should only modify this setting if
there is a known packet size restriction in
the path between the Cisco TelePresence
Server and potential connected endpoints.
