Overview

SatNet AmerHis Mesh Terminals Advantech Satellite Networks AmerHis terminals are full-featured DVB-RCS compliant terminals. These rackmountable units are a slim 1U form factor. They are configurable configurable and out-of-the box ready for use in the AmerHis Mesh system.
The SatNet AmerHis Terminal offers simple connectivity to your corporate LAN and is one of the fastest satellite interactive terminals available today. A truly corporate solution, the Model 2020 is designed to provide enterprise level quality of service demanded of today’s connected world.
As a replacement to your existing T1 or E1 line or as a backup, the Model 2020 always-on performance provides bandwidth when you need it. Designed to support up to 20Mbps on the AmerHis forward link and up to 4 Mbps on the return channel.

AmerHis System
The AmerHis system is compliant with the standards DVB-S and DVB-RCS. The compatibility with these two standards is combined together with multispot capabilities and full mesh connectivity between the different U/L and D/L beams in the system. This allows User Terminals (RCST) to be directly connected. The Gateways (RSGW) provide access to terrestrial networks. The Network Control Center/Network Management Center (NCC/NMC) is responsible for managing on-board resources and user terminals. The following figure illustrates this new concept:

The main characteristics of the AmerHis system are:
ƒ The up-link uses MF-TDMA according to the DVB-RCS standard, MPEG profile
ƒ The down-link is fully DVB-S compatible
ƒ A digital processor on-board the satellite allows to route MPEG packets from up-link to downlink beams in a flexible way with on-board multicast support
ƒ The system implements a sophisticated connection control scheme, called C2P (note: this is not the same than the SatLabs’ CCP protocol), allowing point-to-point as well as point-tomultipoint connections
ƒ The system supports single hop connectivity between users (mesh connectivity) system; C2P allows to establish connection between Gateway and RCST
ƒ The SatNet AmerHis Terminal can be reconfigured to support regular DVB-RCS star and/orAmerHis mesh system through through two different software loads
ƒ Beam coverage: Ku band, Europe, Brazil, North and South America
ƒ The system supports symmetric predictive traffic, as well as bursty traffic generated by a large number of users, owing to dynamic allocation
ƒ The system supports access to external networks via the RSGWs such as PSTN and ISDN as well as private IP networks belonging to ISPs
ƒ The system supports integrated IP based data services
ƒ ISPs can manage their own low-cost gateway (RSGW) and provide Internet access to their subscribers; services such as VoIP and video conferencing can be provided; ISPs choose their own SLAs
ƒ Companies can set up their own VPNs and share their allocated capacity between all their sites; the AmerHis system allows the scheduling of specific connectivity requirements
ƒ The AmerHis payload offers multiplexing and demultiplexing of MPEG-2 transport streams and is therefore capable of offering IP services over MPEG-2 as well as routing video
