The HN1040 Voice Appliance is a state-of-the-art telephony device that provides efficient telephone and fax connectivity via the HUGHES� HN and HX networks. The HN1040 is an excellent solution for the enterprise, kiosk, Internet caf�, or telephony markets where reliable low-cost telephony service is needed. This inexpensive add-on provides telephony services that can generate additional revenues for value-added resellers (VARs) and service providers. The HN1040 provides up to four toll-quality telephone or Group 3 facsimile channels via satellite to the PSTN or, optionally, to a Voice over IP (VoIP) network.
The HN1040, a simple addition to either the HN or HX terminals, provides the transport for carrying telephony traffic via satellite to the Hughes Network Operations Center (NOC). In a typical configuration, a voice gateway at the NOC provides connectivity to the PSTN. The standard H.323 protocol suite is used between the HN1040 and the gateway for call setup and teardown.
Implementing the G.729AB 8 kbps voice codec with echo cancellation, voice activity detection, and comfort noise generation, the HN1040 offers superior telephony quality. Facsimile calls are supported using the T.38 fax over IP protocol to rates of 9.6 kbps. The HN1040 also supports a flexible dialing plan.
Optimized for use with the HN and HX systems, the voice appliance automatically reserves bandwidth through an HN or HX network when each call is initiated. Additionally, the HN1040 and the NOC components prioritize the associated voice stream to ensure end-to-end toll-quality transmission of the call. The prioritization of voice over data significantly improves the quality of service. The HN and HX systems also facilitate short call setup times�typically less than four seconds�and low end-to-end delay inside the HN and HX networks. Transmission efficiency is further improved by compressing the voice packets.
The Hughes NOC equipment routes the voice calls to the PSTN via an H.323 voice gateway. The voice gateway performs the conversion from the H.323 protocol and the PSTN signaling. The voice gateway provides an E1 interface to the PSTN. Multiple voice gateways may be configured at the NOC. A gatekeeper provides the address resolution between the HN1040 and multiple voice gateways. Alternatively, the voice appliance facilitates international long-distance calling to any phone by connecting, via the NOC, directly to a network of multiple Points of Presence (POP) around the world. When integrated with technology from authorized VoIP service providers, the HN1040 supports such advanced features as Interactive Voice Response (IVR) and easy-to-use online account management.
The HughesVision� Network Management System (NMS) provides monitoring and control of the voice appliance, as well as the HN and HX terminals. Downloads of software and configuration parameters are also performed by the NMS.
