    TAU-72.IP/TAU-36.IP Universal Network Terminal allows to connect analogue phone units to packed- based data networks accessible through copper-wire or optical Ethernet interfaces. TAU-72.IP/TAU-36.IP could be used as a subscriber access point utilizing SIP/SIP-T and H.323 protocols and provides a perfect telephone communication solution for underpopulated areas, offices, dwellings and geographically dispersed facilities.

  • Page 10: Product Description

    2 PRODUCT DESCRIPTION 2.1 Purpose TAU-72.IP/TAU-36.IP is a subscriber VoIP gateway with integrated Layer 2 Ethernet switch that uses copper-wire and optical Gigabit Ethernet interfaces to establish connection to provider's IP network. In order to transfer data via IP networks, device converts analogue voice signals to digital data packets.
