Texas Instruments (TI) is talking to telecommunications equipment manufacturers and network operators about adopting a unified DSL standard called Uni-DSL (UDSL) which incorporates all the DSL types - ADSL, ADSL2, ADSL2+, VDSL, VDSL2 and UHDSL (ultra high-speed DSL).
"We’re in discussions with worldwide operators on the concept and we’re in strategic discussions with key customers," said Michael Seidl, TI’s European DSL business development manager for broadband communications.
TI intends to start production of UDSL chip-sets in June 2005, with the first equipment to use them coming out in June 2006 and with projected mass deployment in June 2007.
The idea is to cater for the different geographical ambitions of the telcos and the different requirements of consumer with one universal chipset.
For instance, France is focusing on video over low data rates (6-10Mbit/s); Italy is focusing on video over high speed DSL (10Mbit/s symmetric); the UK and Germany are mainly concerned with achieving 100 per cent coverage; Japan is going for fibre plus VDSL; Korea is targetting high data rate; China wants ADSL with reach extension and is not, yet, concerned with high data rate.
Therefore, a UDSL chipset ranging from the 8Mbit/s of ADSL up to the 100Mbit/s symmetric of UHDSL, should suit all geographies.
"It provides a universal service so a consumer can sign up to anything he likes," said Seidl. For network operators it allows the provision of the ‘triple play’ of voice, video and data.
UDSL will be backwards compatible with installed equipment. "It allows operators to provide all DMT-based services off one line, and on home gateways, making deployment more affordable," said Seidl.
