The HN1040 Voice Appliance is a state-of-the-art telephony device that provides efficient telephone and fax connectivity via the HN network. The HN1040 is an excellent solution for the enterprise, kiosk, Internet cafe, 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 the HN terminal, provides the transport for carrying telephony traffic via satellite to the 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.
