Texas Instruments introduced a new 16-port, multi-service ADSL central office (CO) chipset for both new and legacy ADSL standards. The two-chip “AC7” implementation, which represents 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 line card with software provisioning. The AC7 is expected to begin sampling in 4Q 2003 with full production expected in early 2004.
Texas Instruments said that supporting the full suite of DSL 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.
