Used Cisco IP/VC 3500 Series Videoconferencing System

Product Overview

The Cisco videoconferencing solution is the Cisco IP/VC product family, which comprises several products. The new IP/VC 3500 Series consists of the IP/VC 3510 Multipoint Control Unit, the IP/VC 3520 and 3525 Gateways, and the IP/VC 3530 Video Terminal Adapter. In addition, the Cisco Multimedia Conference Manager is an H.323 gatekeeper/proxy. The Cisco IP/VC product family is designed to work with H.323-standards based videoconference client devices from a variety of vendors.

These products, and the solutions they enable, are developed for enterprises and service providers who want a reliable, easy-to-manage, cost-effective network infrastructure for videoconferencing applications deployment. The Cisco IP/VC product family enables videoconferencing over IP networks, and at the same time, integrates legacy H.320 systems and networks protecting original investments that enterprises make in videoconferencing.

The Cisco IP/VC 3510 Multipoint Control Unit (MCU) enables conferences between three or more endpoints. Multiple participants in multiple locations can attend the same meeting with full real-time interactivity. The IP/VC 3510 MCU is designed to allow users to spontaneously initiate full multimedia, multipoint conferences, including data conferencing. It runs unattended-there is no need to schedule conferences in advance.

The IP/VC 3520 and the IP/VC 3525 Gateways are self-contained systems that translate between H.323 and H.320 protocols. These gateways let users connect IP-based H.323 videoconference networks to legacy circuit-switched H.320 networks. Like the IP/VC 3510 MCU, the IP/VC Gateways offer built-in gatekeeper functions for small videoconferencing networks, a compact design, and reliable RISC architecture.

The IP/VC 3530 Video Terminal Adapter (VTA) is a self-contained video interface that connects one H.320 system to an IP network. It allows companies to protect their investment in legacy technologies while implementing new IP-based multimedia communications. The IP/VC 3530 VTA connects an H.320 room-based system or small-group system to a LAN. It offers two V.35 WAN interfaces, EIA/TIA-366 signaling, a low-profile compact design, and RISC architecture to ensure reliability and easy installation.

The Multimedia Conference Manager (MCM) software is part of Cisco IOS Software. It functions as a high-performance H.323 gatekeeper and proxy, enabling network managers to control bandwidth and priority settings for H.323 videoconferencing services based on individual network configurations and capacities. The MCM is available across a wide range of Cisco router platforms, including the Cisco 2500, 2600, 3600, and the MC3810 multiservice access concentrator.

Key Features and Benefits
