ADSL to go over ISDN

Antony Savvas

Lucent has moved into the broadband asymmetrical digital subscriber line (ADSL) market in a big way with a solution that can run over existing ISDN lines.

The Stinger ADSL-over-ISDN interface module is aimed at those service providers who are looking to coax users into providing faster and feature-rich content over their ISDN lines at speeds of up to 8mbps.

Lucent has not announced any UK operators that will use Stinger, but users should be aware that users in Germany have had difficulty combining ADSL infrastructure with ISDN systems. Although crosstalk interference was a problem in Germany, Deutsche Telekom has gained a lead on UK telecoms providers by selling ADSL as an "upgrade" to ISDN.

Lucent feels the opportunity of bringing in ADSL over ISDN is too good to miss because of the high number of ISDN lines across Europe compared to the US.

Lucent's ITU-approved solution supports all types of digital subscriber line (DSL) service, including the slower G.Lite version, which is cheaper to implement.
