Alcatel uses TI DSPs for VoDSL solution
Alcatel is incorporate TI's programmable DSPs into its leading central office VoDSL solution, enabling service providers to maximise revenue for digital voice services over existing copper
Alcatel, the world leader in DSL equipment, currently uses TI's DSPs and Telogy Software products in its Speed Touch integrated access devices (IADs). The agreement is now extended to the central office to include Alcatel's 7300 Advanced Services Access Manager (ASAM), the world's most widely deployed broadband access platform.

Alcatel's 7300 ASAM makes optimal use of the network's bandwidth resources to more efficiently deliver multiple toll-quality voice lines and data simultaneously with the use of Telogy Software products.
By using TI's voice-optimised DSPs and Telogy Software products, Alcatel's 7300 ASAM will support a broad set of carrier class features including tone detection and generation, voice activity detection, echo cancellation up to 128ms, comfort noise generation and fax relay.
The 7300 ASAM's integrated VoDSL gateway will also support a range of voice encoding technologies including pulse code modulation (PCM) and adaptive differential PCM (ADPCM).
In addition, Telogy Software products support the ATM Forum BLES standard.
TI's programmable TMS320C5421 DSPs and Telogy Software products provide future-proof technology allowing Alcatel to upgrade its VoDSL solutions for the purpose of adding new features and supporting evolving standards.
Programmable DSPs, such as TI's voice-optimised TMS320C5400, are required for telecommunications applications where real-time algorithm processing is needed since the DSP can perform the necessary multiply-accumulates for MIPS-intensive or high-bandwidth applications such as voice processing.
Moving forward, TI offers manufacturers a competitive roadmap that combines Telogy Software products such as low-bitrate codecs with the higher density and performance of the new TMS320C5500 family.
