© 2008 Cisco Systems, Inc. All rights reserved. 3 Cisco TelePresence Interop Key Messages  Cisco TelePresence is based on open standards, including SIP, H.264, AAC-LD and G.711  Provides interoperability between TelePresence and standard- definition Videoconferencing / Video Telephony  Solution will maintain the rich, immersive experience between TelePresence participants, while providing a bridge to existing Videoconferencing / Video Telephony devices  Leverages the existing Cisco Unified Videoconferencing 3500 Series (CUVC) Multipoint and H.320 ISDN Gateway products Cisco has been offering the CUVC family since CUVC has a proven track record of interoperating with virtually all vendors/models/versions of H.323 and H.320 –based Videoconferencing and SCCP –based Video Telephony equipment

All rights reserved. 12  CUVC 5.5 and 5.6 are the only supported model of MCU  The CUVC MCU must be dedicated to TelePresence and controlled by Cisco TelePresence Manager. You cannot share this MCU with CUCV-M or Cisco MeetingPlace controlled meetings  Encryption is not supported for interop-enabled multipoint meetings (e.g. Secure RTP (sRTP) on the TelePresence side does not interoperate with H.235 on the Videoconferencing side)  TelePresence participants and CUVC participants will not be able to share slides, documents or document cameras (e.g. Auto Collaborate on the TelePresence side does not interoperate with H.239 on the CUVC side Recommend using MeetingPlace or WebEx to facilitate collaboration  Far End Camera Control (FECC) will not be provided. TelePresence participants will not be able to control (zoom, pan or tilt) the cameras of CUVC participants  Reduces CTMS and CUVC port capacity by 1 per meeting. E.g. CTMS can support up to 48 segments, and CUVC can support up to 24 participants. Reduce by 1 each for each simultaneous meeting Cisco TelePresence Interop Other Caveats / Limitations
