Next-generation product line integrates DVB-S2/ACM efficiencies into iDirect’s Intelligent Platform

Herndon, Va., June 17, 2008 – VT iDirect, Inc. (iDirect), a company of VT Systems Inc (VT Systems) and a world leader in satellite-based IP communications technology today launched the first suite of DVB-S2/ACM products in its Evolution product line – the Evolution X3 router, XLC-10 line card and iDX software. These new products enable service providers to leverage the benefits of DVB-S2 with Adaptive Coding and Modulation (ACM) to lower operating costs and increase their business opportunities. The Evolution offerings complement iDirect’s widely-deployed, award winning iNFINITI product line.

The Evolution X3 is an integrated satellite modem and IP router with Ethernet interface. The X3 maximizes bandwidth efficiency, featuring DVB-S2/ACM on the outbound carrier and iDirect’s patented, deterministic TDMA on the inbound channel. It supports a wide range of IP data rates, carrier modulations and FEC codes, including downstream modulations of up to 16APSK and upstream modulations of 8PSK. The Evolution product line, which includes the XLC-10, iDX and X3, enables satellite networks to reach data speeds of up to 156 Megabits per second.

Extensive tests show that the Evolution product line can deliver a 30 percent improvement in bandwidth efficiency over DVB-S systems. An additional gain of 50 percent is possible through ACM, an advanced feature of the DVB-S2 standard which iDirect has built into its Evolution product line.  These dramatic gains open new opportunities for service providers to improve support for a range of IP applications, including virtual private networks (VPN), voice over IP (VoIP), videoconferencing, enterprise networks, point of sale, SCADA, telemetry, multimedia and Internet cafes.

The new Evolution product line fully integrates with the advanced features of the iDirect Intelligent Platform to help operators amplify the gains of DVB-S2. One of the platform’s key features, Group QoS, enables service providers to combine multiple small networks into a single, larger carrier that is better able to leverage the efficiency of DVB-S2/ACM. In addition, new features have been built into iDirect’s iVantage network management system that allow service providers to track ACM gains in real time and configure their networks to optimize bandwidth efficiency.

With Evolution, service providers can readily upgrade to DVB-S2/ACM in their existing iDirect chassis. Once in place, feature enhancements and updates can be made instantly with over-the-air software upgrades.

“With Evolution, our customers can take full advantage of the new standard’s efficiencies and better meet the demands of organizations that require constant broadband connectivity for every application and geography. We’ve gone to great lengths to ensure that our system can be quickly implemented and easily expanded. ”
