Internet Backbone Connectivity

An IP backbone link provides a uni or bi-directional, symmetrical or asymmetrical point-to-point connectivity between two parts of the Internet or a private network. InSat offers ISPs, telecommunications companies, and corporate clients Internet access via quality, reliable satellite links using DVB-S2/SCPC technology.

Satellite is the ideal solution to provide backbone connectivity to regions that have no access to a fiber or undersea cable infrastructure, or when the backbone link needs to cross regions that cannot be secured. It is also the fastest method to recover from a loss of connectivity due to a cable failure or natural disaster.
Because satellite is a communication system with very specific constraints, connecting two parts of an IP network over satellite requires specific solutions, but InSat provides an end-to-end solution that routes, encapsulates, secures, accelerates and shapes the satellite IP traffic in simple yet very bandwidth-efficient way to connect two routers over satellite.

Modern methods of digital high-level modulation and redundancy coding ensure high service reliability at acceptable capital and operating costs.

Backbone Internet connectivity is provided in two forms:

· one-way access using DVB-S2 technology, where the uplink is via a land line;

· two-way access using DVB-S2/SCPC technology, where both uplinks and downlinks are by satellite.

The most economical form is to use links via inclined-orbit satellites. These are satellites that have expended their orbital correction fuel and no longer retain their geostationary position. So the satellite antenna must be equipped with an automatic tracking system that follows the satellite. This technical complication is balanced by a substantial reduction in the cost of the service (by more than half) without loss of reliability.

Capabilities of the service:

1. Point-to-point connection or point-to-multipoint connection with separable downlinks;

2. Guaranteed CIR speed and peak PIR in each client line;

3. Use of the VCM option of the DVB-S2 standard to expedite installation of new ground stations and reduce capital costs;

4. Use of the ACM option of the DVB-S2 standard to ensure the highest service reliability under varying weather conditions;

5. C and Ku bands;

6. Transmit bands from 128 kbps to 160 Mbps, easy expansion of required band as necessary;

7. Geostationary and inclined-orbit satellites;

8. Use of equipment from leading world manufacturers;

9. 24/7 multilingual technical support with response time from 30 minutes;

10. Remote monitoring of client terminals to ensure proactive emergency response.
