  1. MGC Release 7.0 Product Update Presentation

  2. MGC Release 7.0 Introduction Release 7.0 is focused on the following areas: • New ISDN and IP resource modules • SIP • IP Enhancements • Reliability – IP & Unified Conferences • Security • Quality Of Conferencing Experience – Video, Audio & Content

  3. MGC Release 7.0 Highlights New Resource Modules SIP Support IP Enhancements

  4. MGC Release 7.0 Highlights Reliability for IP Conferences Reliability for Unified Conferences

  5. MGC Release 7.0 Highlights Security Quality Of Conference Experience - Video Quality Of Conference Experience - Content

  6. MGC Release 7.0 Highlights Quality Of Conference Experience - Audio

  7. New ISDN Resource Modules • 3 new modules: Mux+ 10, Mux+ 20 and Mux+ 40 • Mux+ is required for AES encrypted ISDN participants • Unused reserved Mux+ resources can be freed up for other users • Dynamic allocation of Mux resources according to bandwidth requirement – Mux 10 supports 10 sites @ 384 kbps, 20 sites @ 128 kbps • Mux and Mux+ can be combined in a conference - AES uses Mux+ • If AES is disabled, first Mux resources are used, then Mux+

  8. MUX+ Advantages • Higher capacity and encryption: The MUX+ has enhanced functionality compared with the current MUX board • Enhanced trace mechanism – MUX+ logger is used to retrieve diagnostic file when a MUX+ module shows a fault • Flexible ports: Eliminates the traditional limitation of configuring the MUX per rate and decreases resource fragmentation

  9. Mux+ Capacities & Prices Driving Down the price of ISDN! • Pricing includes • - Bonding • - H.320 port licenses • All new systems will ship with the new MUX+ modules

  10. New IP+ Resource Modules • Release 7.0 includes new IP 12 and IP 24 resource modules, built on the same design of the existing IP 48 module • AES and SIP: • New IP+12 and IP+24 support AES and SIP for the MGC 50/100 • Existing IP12 and IP24 modules do not support AES and SIP. • IP12/24 and IP+ modules can be used in the same conference. IP+ is used for SIP and AES participants. • Capacities on all IP+ modules are halved when AES is enabled

  11. SIP – Session Initiated ProtocolNext Generation IP conferencing • Audio, video and unified conferencing, using SIP • Interop support for industry leading desktop applications: • Polycom Web Office • Microsoft LCS • Nortel MCS • Others to follow …. • Bridge the “old” and “new - SIP” worlds • Support for ISDN, H.323 and SIP participants all in same conference • Enable new services based on SIP capabilities • Complete Polycom SIP solution • MCU, A/V Endpoints, user and admin portal, SIP server, NAT / Firewall traversal solution Unified Conferencing=(H323+H320+SIP)(A/V/D)

  12. SIP support for Unified Conferencing • On-demand, Reserved, attended and unattended conferencing • Support for key multipoint conferencing scenarios • Direct Dial in, “Single Dial” service, ad-hoc (external DB integration), “Dial-out” – auto / manual / blast / by sub-groups • All currently supported audio / video algorithms • Transcoding and CP support • Integration with Microsoft-LCS and Nortel-MCS environments • Client based “Buddy list” to join a conference • Multi-party IM session can be converted to and A/V/D conference run on MGC

  13. SIP MGC Notes • MGC 50 – MGC 100 Hardware Requirements • the existing IP48+ modules (v 4.23 and higher) • the new IP+12 and IP+24 modules • MGC 25 is already enabled to support SIP • Included in the MGC for No Charge. No license is required.

  14. IP Enhancements • Entry Queue graphic display (welcome slide) for both H.323 and SIP based video endpoints • H.323 Far end camera control – MCU & GW • H.323 Annex Q - H.281 over H.224 • Radvision’s proprietary FECC

  15. IP Conferencing Reliability • RTP Monitoring • RTP packets: loss, out of order, fragmented packets • Jitter mechanism: buffer size, late packets, overflow • Info per each media channel (audio in/out, video in/out, content) • DHCP • IP media interface can now obtain its IP information address via DHCP • NAT Traversal • MCU inserts external IP addresses as its media channel addresses • Works by Static Mapping – each internal IP address (IP board) is translated into a specific external address • Link DNS name to the IP interface – especially useful in SIP • Alternate GK • Enables redundancy in case the primary GK fails or wants to share its load with other GKs

  16. Any Network Conferencing Reliability The “World’s Best Transcoding” Just Got Better

  17. SecurityAES • Encryption is used to transit Video/Audio securely over IP/ISDN. The sender encodes it, and unless the recipient has the “key” it can’t be read. • MGC version 7 supports standard based AES in IP and ISDN calls • Requires IP+ module for IP calls and MUX+ for ISDN calls • The MGC25 is already hardware enabled to support AES. • Media (A & V) encryption for H.323 and H.320 endpoints • Only P+C and H.239 standard will be supported • CDR - A new field “Encrypted Yes/ No” in the conference level, and in the participant level will be available • Included in the MGC for No Charge. No license is required.

  18. AESSession Guidelines • Encryption is part of the conference reservation, and can not be changed while the conference is on going • The conference settings apply to all participants, a change can be made at the participants level • A combination of encrypted and non encrypted endpoints are allowed with the exception that in the case of a VSW conference all ISDN participants must be the same type (i.e. encrypted or non-encrypted)

  19. Video QualityH.264 Video • Standards based video compression • Uses half the bit rate while providing high video quality at lower speeds • Supported in video switched, continuous presence and gateway calls • Continuous Presence - supports H.264 for IP and ISDN, and can add participants with other protocols (H.261/H.263) • Requires Video+8

  20. Video Quality 4CIF Video In CP/Tx Conferences • MGC Version 7 provides the flexibility to select quality options. Configure via “Media Settings” under “Quality” option: • Motion: CIF resolution only • Sharpness: enable 4CIF • Endpoints that support 4CIF video resolution and endpoints that do not support 4CIF can participate in the same conference, using their optimum capabilities • Standard feature on the MGC video+8 resource module

  21. Video Quality Highest Common Enhancements • Improved MCU connectivity - reduces Secondary connection, due to EP parameters inconsistency • Improved Move between conferences – in general and Entry Queue access conferences in particular (as EQ uses the move mechanism) • Additional parameter support for H.264, H.263 annexes (F, N, T, I*), Pro-Motion, VGA/SVGA/XGA resolutions

  22. Content QualityH.239 • Signaling for H.320 and H.323 will be according to ITU-T H.239 implementation guide • Resolutions: • 4CIF - 704 x 576 • XGA - 1024 x 768 • SVGA – 600 x 800 • The Speaker may switch from People CIF to Content in 4CIF or SVGA/XGA • MGC Transcoding has been extended to support Polycom People + Content and H.239 People + Content in the same conference • H.239 / P+C are supported in cascade between H.323 conferences • Supports Highest Common

  23. Audio QualitySilenceIT • MGC automatically detects noisy lines or music when put on hold, and mutes those participants • Participant is notified if he/she has been muted • Participant has 4 choices to re-join the conference: • Un-mute and re-join • Adjust the SilenceIT algorithm and re-join the conference un-muted • Disable the feature and re-join un-muted • Re-join muted • IVR/DTMF is used to select options • Conference level setting • Enable SilenceIT feature can be selected only if IVR is enabled • Patent pending

  24. Audio QualityAudio Error Resilience • Due to occasional IP network problems, IP packets may get corrupted or lost, resulting in chopped audio. • The MCU has the capability to replace the lost/corrupt audio packets, smoothing out the audio when such conditions occurs. • It is accomplished by storing 40ms of the most recently decoded audio and using this data to generate synthesized audio to replace the packets • It improves the overall quality of VoIP conferencing
