Networks for fixed operators

When trying to deploy area networks, operators frequently face landline monopolization. It is rather difficult for operators to lay their own lines and the expected traffic may not guarantee any return on investment.

Obviously, satellite channels are the only way to rapidly establish a fixed network with points of connection in all communities in a given area. Despite their small size and low cost, VSAT terminals have much traffic-carrying capacity and support various interfaces and signaling systems.

It takes just one day to install a satellite terminal connecting the area operator in a community. Also, the terminal can be used to provide voice and data services to individuals or corporate customers. Even if there is a landline to the point of presence, satellite communications is still a perfect backup solution.

The satellite terminal can be equipped with two or more E1 G-703 interfaces and supports various signaling systems (EuroISDN, Russian standard No.7). Also, analog interfaces can be installed to connect payphones and telephones of end users. An integrated IP port will provide broadband access to external networks (internet) and other stations in the network. This can be used for full-scale services.

The interfaces process and compress voice traffic and signaling by forming IP packets which are then transmitted via satellite to the hub station, routed to the required point of connection and converted by a similar interface to a digital flow with the corresponding signaling. Owing to an advanced compression processor and a speech pause optimization system, voice service in the satellite network uses very little resources.
