CISCO UNIFIED VIDEOCONFERENCING SYSTEM
When used with any of the Cisco Unified Videoconferencing 3500 Series Multipoint Control Units (MCUs), the Cisco Unified
Videoconferencing 3522 and 3527 Gateways facilitate multiparticipant conferences using H.323, H.320, Skinny Client Control Protocol
(SCCP), or Session Initiation Protocol (SIP) endpoints, helping ensure cost-effective local and global participation for multi-location meetings.
The Cisco Unified Videoconferencing 3522 and 3527 Gateways are part of the Cisco family of videoconferencing products that also
includes the Cisco Unified Videoconferencing 3545 Series gateway modules, the Cisco Unified Videoconferencing 3515 and 3545 MCU,
and the Cisco IOS
®
Gatekeeper and IP-to-IP gateway products. In addition to integrating room-based systems, this solution facilitates
video telephony and video-enabled rich-media collaboration.
Table 1 describes the features of the Cisco Unified Videoconferencing 3522 and 3527 Gateways, and Table 2 lists the product
specifications.
