Small System Solutions
For a small system with limited number of conference sites, an MT with embedded MCU will be adequate to link multipoint MTs and control conferences without the need of any additional stand-alone MCU’s, as shown in Figure 1. The initial investment therefore is limited. An MT with an embedded MCU in the headquarters provides MCU functions for as many as six sites, besides its own MT functions. Each remote MT is chosen according to the application and the size of the meeting room to link to the central MT/MCU.

The TrueSens system provides complete embedded MCU functions, compared to the simplified embedded MCU in traditional systems. TrueSens’ embedded MCU terminal features a powerful access mode through dual network interface in multiple network sections and delivers gatekeeper, firewall/NAT traversal functions. Any conference site, whether through Internet or VPN/Intranet access, can be accessed directly, thus allowing quick deployment in different network environments without the necessity of an additional PC or server. Other features such as Continuous Presence (CP) and mixing enable an effective multipoint conference. The launch and management of a conference can be operated on a remote control.
 

Large and Medium System Solutions
For large-/medium-sized systems, an independent high-performance MCU can be configured in the headquarters to achieve multipoint access and conference control. The conference rooms at headquarters and remote branches are equipped with MTs according to the requirements of the sites, as shown in Figure 2.

The system provides access for several to dozens of conference sites. Multiple meetings can be held at the same time. A stand-alone MCU delivers key functions such as gatekeeper and firewall/NAT traversal. Additional gatekeeper server or proxy server is not required. This unique and simplified architecture reduces investment costs and improves manageability as well. The system’s powerful media processing capability enables advanced applications including CP, mixing and code stream adaptation, resulting better performances in a multi-party conference.
 

Multi-ISP Solutions
The innovative built-in multi-ISP connection mechanism by Kedacom flexibly allows multiple accesses through different Internet service providers to eliminate bandwidth bottlenecks among multiple ISP, as shown in Figure 3.
