Texas Instrument Unveils DSL Central Office Design for Telco Triple-Play

Texas Instruments unveiled an Integrated Voice and Data (IVD) reference design that enables triple-play delivery of voice, video and data over DSL. The design combines TI's central office chipset and narrowband POTS voice functionality with its Telogy software for Voice over Packet (VoP). TI said the new platform would allow service providers to quickly deploy IVD line cards in DSLAM, DLC and MDU applications to upgrade their large installed base of POTS subscribers for DSL service.



TI's AC7 IVD platform utilizes Wntegra's WinPath Access Packet Processor for VoP, DSL and IP multicast traffic aggregation and data management. Both VoP and packet aggregation capabilities can be provided as add-on modules. The line interface for POTS is managed by Legerity's subscriber line interface circuit (SLIC) and subscriber line audio-processing circuit (SLAC) technology, providing fully programmable transmission and loop supervision parameters.



The AC7 IVD solution's lead customer is Fujitsu Telecommunications Europe Limited where it is used in the company's Access Gateway platforms for residential and business service. Fujitsu's Integrated Voice Line Card Subsystem provides ADSL and voice from a single unit providing V5, ATM BLES or H.248 options for signaling. http://www.globalcrossing.com
