New AVC CP Profile - General Parameters

Line Rate

Routing Name
Polycom®, Inc.
Description
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.
 Up to 1Mbps for SD30, CIF60 and below
 Up to 4Mbps for SD60, HD720p30
 Up to 6Mbps for HD720p60, HD1080p30, HD1080p60
(RMX 1800 with no DSP cards 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
for Resolutions table.
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.
Enter the Profile name using ASCII characters set.
The Routing Name can be defined by the user or automatically generated by the
system if no Routing Name is entered as follows:
• If an all ASCII text is entered in Display Name, it is used also as the Routing
Name.
• If any combination of Unicode and ASCII text (or full Unicode text) is entered in
Display Name, the ID (such as Conference ID) is used as the Routing Name.
