From TI’s press release:
Texas Instruments Incorporated (TI) today introduced two new DSL residential gateway reference designs that add Voice over Internet Protocol (VoIP) and wireless home networking functionality. The new designs are based upon TIÂ´s AR7 DSL router-on-a-chip and combines key technologies of TIÂ´s broadband portfolio. These DSL, VoIP and WLAN technologies were designed to allow future system-level integration with platforms containing common hardware and software architectures. This design strategy made it possible to integrate the AR7 with TIÂ´s 802.11b/g platform and voice DSP with Telogy Software into a single system that provides consumers with cost-effective VoIP and WLAN for their homes.

The newest members joining AR7 and AR7W in the AR7 family are the AR7VWi and AR7V. The AR7VWi combines VoIP, 802.11b/g wireless home networking and DSL into a single platform. The AR7V provides VoIP over DSL. Manufacturers can use the AR7 family to develop complete ADSL product lines that are operator quality and deployment ready, due to extensive testing performed on the family in TI’s broadband labs and the field hardening that has occurred through real world deployments.
“DSL operators are striving to diversify their products by offering premium and bundled services at affordable prices to consumers,” said Mike Wolf, director of Enterprise and Residential Communications, In-Stat/MDR. “TI’s AR7 family is the perfect solution to fulfill this need. Operators can now cost-effectively deliver VoIP services and home networking, by using TI’s designs to provide VoIP over DSL, or with WLAN added on an integrated, easily deployable solution.”
Flexible, Integrated Solutions
The AR7 family enables manufacturers to quickly and easily deploy products with significant design reuse and reduced complexity. TI reduces the bill of materials (BOM) for VoIP DSL systems due to the motherboard level integration in the AR7VWi and AR7V. The AR7 family uses TIÂ´s low cost VLYNQ chip-to-chip serial interface to provide superior performance from the AR7 to the VoIP and WLAN sub-systems. With VLYNQ, manufacturers can add on-board co-processors and peripherals that transform their products into enhanced communications devices. TIÂ´s common DSL, VoIP and WLAN hardware and software architectures maximizes reuse across the product lines, further decreasing costs for manufacturers.
“TI is using our expertise, broadband portfolio, and understanding of OEM and operator needs to lay the perfect framework to take broadband to the next level of triple play services,” said Greg Jones, general manager of TI’s DSL Business Unit. “Adding reliable, proven VoIP and Wi-Fi capabilities to routers makes DSL services more attractive and will help operators add services to maintain and grow their subscriber base.”
One Family – Four Product Offerings
The new AR7 designs integrate TIÂ´s industry leading silicon and Telogy Software for VoIP. TIÂ´s VoIP solutions represent over 80 percent of the total VoIP integrated circuit (IC) shipment volume*. A full implementation of voice features that include echo cancellation, voice packet playout software, tone processing, voice activity detection, and multiple low bit rate (LBR) voice codecs for bandwidth reduction are included with the AR7V and the AR7VWi.
TI’s Linux Network Support Package (NSP) can be used with the AR7-based solutions to solve Quality of Service (QoS) challenges for voice. The advanced QoS implementation dynamically allocates the limited upstream bandwidth resources for optimum performance based on the ADSL line’s capabilities. The NSP provides four priority queues to enable the superior quality levels of voice and data over the ADSL connection. Dynamic Packet Fragmentation optimizes the use of upstream bandwidth available for data traffic after the voice packets are prioritized.
The AR7VWi, like the AR7W, includes TI’s TNETW1230 802.11b/g platform, so consumers can access broadband content and applications from anywhere in the home without wires. The AR7VWi will include the 802.11g throughput enhancement and reach extension technologies that TI plans to unveil later this year. These will deliver the throughput consumers need for multimedia applications and longer network range to cover an entire house with the maximum bandwidth available.
The AR7 family supports all existing DSL standards, including the new ADSL2 and ADSL2plus standards, enabling download speeds up to 24Mbps. For more information on the AR7 see: www.ti.com/ar7.
Full scale production and end-equipments based on the AR7V and AR7WVi are expected in June 2004.
