DSL Solutions Based on TI's Next-Generation UR8 Residential Gateway Architecture

The UR8 architecture comprises an advanced multimedia gateway processor, a programmable DSL PHY, a high-performance DSP-based voice sub-system and a rich set of local area network (LAN) interfaces. Multiple processors enable the intelligent management of broadband distribution for enhanced throughput and performance. A well-defined application program interface (API) reduces time to market by allowing hardware and software reuse across all DSL platforms.



The UR8 architecture leverages a dedicated DSP to enable exceptional voice capabilities and delivers on TI's vision of Fixed Mobile Convergence (FMC) throughout the home with support for up to four

channels of wireline or wireless voice. Its high-performance programmable voice subsystem allows manufacturers to leverage TI's extensive voice codec library and Telogy SoftwareTM for VoIP, including

wideband codecs, wireline and wireless codecs, and advanced features such as fax and modem relay, packet-loss minimization and noise-reducing algorithms.



The UR8 architecture also has a rich set of interfaces to support distribution of broadband services throughout the home over multiple home networking technologies, including Ethernet, WiFi and standards offered by the HomePlug Powerline Alliance, Multimedia over Coax Alliance and Home Phoneline Networking Alliance (HomePNATM).



In addition, the UR8 platforms leverage the extensive interoperability footprint of TI's field-proven AR7 product family to enable manufacturers to take advantage of existing product investments to

develop high-performance, interoperable next-generation RG solutions.
