New Product Orderability Announcement:
Cisco IP/VC 3500 Series Gateway Version 2.0

April 7, 2003

The IP Communication Business Unit is pleased to announce availability of its new IP/VC videoconferencing gateway version 2.0. Videoconferencing gateways bridge the gap between the installed base of ISDN videoconferencing systems and the rapidly growing number of IP-based H.323 systems by translating calls from ISDN to IP (and IP to ISDN) to reach video endpoints on the IP network. The gateway connectivity enables worldwide reach and greater return on investments in existing ISDN equipment.

IP/VC gateway version 2.0 introduces new advanced features designed to provide high quality, high availability call management with enhanced packet handling and integrated network resource management. Overall, these improvements will raise the level of reliability, functionality and quality of a videoconferencing meeting.

The new gateway version 2.0 is available on these IP/VC gateway platforms:

Customer Benefits

Productivity Tool—Videoconferencing is a proven tool reducing customer travel costs and unproductive time while enhancing meeting capabilities and increasing employee productivity. The videoconferencing gateway allows for worldwide connectivity of videoconferencing solutions.

Return on Investment—Customers can increase the return on their network investment by converging voice, video and data solutions across one network. Videoconferencing gateways are a shared resource on the network helping to reduce costly ISDN connection to each end point.

Greater Flexibility—With IP, deploy videoconferencing systems and endpoints anywhere you have an IP network connection. The videoconferencing gateway allows customers to migrate to IP videoconferencing at their own pace by allowing communication between their new and old videoconferencing networks.

Improved Management—Gateway version 2.0 improves the look and feel of the interactive graphic user interface (GUI) making management and access to system information simple and intuitive.
