SCS-8000E is configured of access capacity of 8 ~ 64 channels, with convention of 16 group meetings at the same time. Each access node supports a streaming bandwidth up to 4 Mbps. It is very suitable to multiple access networks with different bandwidth conditions such as the Internet, leased lines and LANs.

- Excellent Network Adaptability
With the embedded proxy service, SCS-8000E supports NAT/firewall transversal and allows to deploy endpoints at any place without interference of network security policy. Using Intelligent Packet Loss Recovery (IPLR) and QoS technologies, SCS-8000E ensures operation stability under various network environments, even through ADSL access from a remote site, your access quality to conference can also be maintained satisfactory.

- Powerful Conference Features
With a layout of 4, 9, or 16 sites in Continuous Presence and function of Intelligent Audio Mixing, SCS-8000E supports a perfect interactive conference with multiple parties. Conference template and conference booking command allow you to originate a conference with number of participants and various preset parameters, anytime just by simple button click. Furthermore, you may use Meeting Control System (MCS), a friendly GUI software for a complete conference management.

- High Security and Reliability
SCS-8000E gives a high-reliable 128-bit encryption mechanism to insure conference information security. Its embedded design architecture and strict authentication policy can completely protect system safety and prevent unauthorized access.

- Cost Effective and Protect Investment
With a single hardware platform, embedded design architecture integrated with services such as GK, proxy and T.120, SCS-8000E is an all-in-one solution for functions provided by multiple devices or servers otherwise. Therefore, your system setup and maintenance cost will be tremendously reduced. Since the system can be upgraded through software to higher version in terms of capacity, new protocols and features, your investment is fully protected.

MCU typically is deployed at corporations’ headquarters. It is responsible for the connections with the endpoints and the switching, transferring and processing of audiovisual data streams of the conference. For large systems, Samcen’s high-performance MCU (SCS-8000E) is recommended to provide connection and control at the headquarters. A typical network structure is shown in Fig. 1.

SCS-8000E has built-in gatekeeper and NAT/Firewall traversal capabilities. Therefore, no additional gatekeeper or proxy server is required. This has resulted in simple network structure, low investment cost and improved manageability.

SCS-8000E allows up to 64 conference connections and multiple conferences at the same time. Its powerful processing capability supports video synthesis, audio mix and auto transmission speed, achieving the highest videoconferencing performance.

In addition, the system’s unique multiple ISP access function provides a solution to the bandwidth bottleneck in multiple ISP environment, as seen in Fig. 2.
