![]() BT today confirmed plans to extend the rollout of its wholesale SDSL products to a further 50 exchanges. SDSL gives the same rate of data transfer upstream as downstream. It is particularly suitable for end-users such as SMEs, people in remote offices or teleworkers who require business-class connectivity to their service provider for applications such as fast file transfer and web hosting. BT Wholesale launched its SDSL services in September 2003 on 100 exchanges serving metropolitan areas in London, Greater Manchester, Merseyside, Yorkshire, the West Midlands and Scotland. A further 50 locations have now been selected on the basis of demand, market analysis and feedback from service providers. Exchanges to be upgraded in this phase of rollout will be in Greater London and West Midlands. BT Wholesale is planning to enable these exchanges by the end of January 2004. From http://www.btplc.co.uk/Mediacentre/A...03/an03161.htm which includes a list of exchanges. Regards Sunil |

SDSL gives the same rate of data How does SDSLs attenuation limits compare with ADSL? They are lower as SDSL is the same speed in both directions - I did hear a figure of 35dB quoted but thats unconfirmed - that would compare to a 45dB figure for 1 or 2MB ADSL Is SDSL merely a software switch, or does it require extra hardware at the exchange? I believe all the DSLAM's that BT have fitted can potentially support SDSL if upgraded via software. Though I imagine the reason its not being rolled out nationwide is given the way BT operate, they are deciating a DSLAM to SDSL rather than having the two services sharing the "same" equipment. BT have an SDSL checker at http://62.172.198.79/broadband1/gett...about_sdsl.asp Note: The SDSL products in Central London are actually supplied over Bulldog's network, which BT Wholesale resell. Bulldog resell BT Wholesale SDSL on the other enabled exchanges. Regards Sunil |
