Defining AVC-Based Conference Profiles
Polycom®, Inc. 42
Line Rate Select the conference bit rate. The line rate
represents the combined video, audio
and Content rate
.
The default setting is 384 Kbps.
Notes:
• This field is displayed in all tabs.
• The maximum line rate at which ISDN endpoints can connect to a conference is
768 kbps.
Downspeeding is not supported. As a result, ISDN calls will consume
bandwidth resources according to the Line Rate specified in the conference
Profile. For example, if the conference Line Rate is 512kbps, ISDN calls
connecting at lower line rates (256kbps) will still consume the bandwidth
resources of 512kbps calls. As a result, if bandwidth resources are fully
consumed, ISDN calls may be rejected before media card resources are
exhausted.
• The Collaboration Server supports AVC-CP conferences at line rates of up to
6Mbps:
For Dial-in calls only.
For use with HD1080p30/60 and HD720p60 resolutions.
To prevent excessive bandwidth usage and resource consumption, the system
will ignore a Line Rate of 6Mbps, substituting line rates appropriate to the
Maximum Resolution defined.
For MPMRx and RMX1800:
Up to 1Mbps for SD30, CIF60 and below
Up to 4Mbps for SD60, HD720p30
Up to 6Mbps for HD720p60, HD1080p30, HD1080p60
For MPMx:
Up to 2Mbps for SD30, CIF60 and below
Up to 4Mbps for SD60, HD720p30 and above
(RMX1800-0 maximum AVC-CP conferencing line rate: 4Mbps.)
• If ‘Maximum Resolution’ is specified in ‘Video Quality Parameters’, the line rate
might be modified automatically according to table ‘Maximum negotiated line
rate for resolutions’.
• If ‘Maximum Resolution’ is specified in ‘Video Quality Parameters’, the line rate
might be modified automatically according to the Maximum Negotiated Line Rate
for Resolutions table.
Conferencing Mode Select the required Conferencing Mode. The selection affects the available tabs
and their fields.
Notes:
• This field is displayed in all tabs.
• If the selected Line Rate is higher than 4Mbps, and Conferencing Mode is
modified to SVC Only or CP and SVC, the line rate is dropped to match
SVC-enabled conferencing rates.
