ADSL CO Chipset from TI Enables New Revenue Generating Services While Reducing Operators' Network Costs

Integrated 16-port Multi-Service, Multi-Standard Platform Supports ADSL, ADSL2, ADSL2plus, Including Extended Reach and Enhanced Upstream Standards

Sep 8, 2003

DALLAS (Sept. 8, 2003) - A new 16-port, multi-service ADSL central office (CO) chipset that reduces operators´ and manufacturers´ total cost of ownership of their ADSL systems was introduced today by Texas Instruments Incorporated (TI) (NYSE: TXN). The chipset raises the bar for integration on silicon for COs with a 2-chip architecture that results in significant cost savings in the manufacturing and operational expenses of ADSL systems. TI is enabling manufacturers and operators to more cost effectively provide and deploy ADSL infrastructure networks by supporting both new and legacy ADSL standards and providing robust interoperability performance. (See: www.ti.com/ac7overview.)
The AC7, TI's seventh-generation CO solution, enables multi-service and multi-standard support of ADSL, including legacy protocols, as well as ADSL2 and ADSL2plus. Included among the features in AC7 are support of reach-extended ADSL2 (G.992.3 Annex L), enhanced-upstream operation enabling upstream bit rates over POTS as high as 3.5 Mbps (G.992.3 Annex J and G.992.5 Annexes J and L). Each of these standards and operational modes can be supported from any port on a single linecard with software provisioning.
This full suite of standards enables operators to tier their service offerings for consumers, offer the triple play of voice, video and data services, and expand their service area to provide DSL to more households. TI's large investment in interoperability testing equipment and labs, along with extensive testing of the AC7 against most major modems, allows operators around the world to protect their installed customer premises equipment (CPE) base.
"TI is addressing the key operator and infrastructure equipment requirements with one DSL CO chipset that enables lower network and system costs with the ability to reach more subscribers," said Matt Davis, director of Yankee Group's Broadband Access Service. "Providing support for multiple ADSL services on any port, TI's AC7 gives operators the ability to offer triple-play and enhanced upstream services to compete in the broadband market without having to completely upgrade their entire infrastructure."

Reducing Total Cost of Ownership

The level of integration achieved by the AC7 enables the highest densities for central office applications. This integration also reduces the total cost of ownership for OEMs and operators to develop, deploy and maintain DSL systems and networks through a variety of cost efficiencies and expense reductions.

For CO equipment manufacturers, the AC7 improves R&D and manufacturing efficiency by:

  • Reducing hardware development expenses through the use of one board for worldwide deployments. 
  • Lowering software development expenses through backward compatibility with previous TI CO chipsets. 
  • Controlling operational expenses through over a 40 percent reduction of active and passive components compared to leading CO chipsets. This results in lower purchasing, inventory and assembly costs. 
  • Optimizing PCB (printed circuit board) complexity through complete integration of all analog signal traces between chipset devices. 
  • Eliminating interoperability risk through high-performance interoperability with previously deployed CPE modems.

For operators, the AC7 minimizes capital expenditures and operational expenses by:

  • Lowering capital expenditures by enabling lower system-level costs while continuing to increase the amount of revenue generating services. 
  • Controlling provisioning expenses through broad interoperability testing for new and legacy standards, minimizing help desk calls and truck-roll dispatches. 
  • Reducing operational expenses by providing the lowest chipset power consumption to limit network-level electricity draw. 
  • Lowering maintenance expenses through advanced levels of integration improving linecard field reliability.

"With the introduction of the AC7, TI continues to lead the industry in integration, performance, quality and interoperability. The benefit to manufacturers and operators is a reduction in their total cost of ownership," said Greg Jones, general manager of TI's DSL Business Unit. "As a multi-service, multi-standard solution, the AC7 protects operators' existing network investment and enables future growth with new revenue generating services with minimal costs."


The AC7 is expected to begin sampling in 4Q 2003 with full production expected in early 2004.
