Alcatel demonstrated one of the industry's first asynchronous digital subscribe line (ADSL) modems for ISDN lines at a European trade show this week.
At Exponet 98 in Dusseldorf, Germany, Alcatel showed off its ADSL modem that delivers data speeds of up to 8Mbps to current ISDN networks. The standard for this was "determined" - or made stable - by the International Telecommunications Union (ITU) last month and is expected to be agreed next June.
ADSL modems for ISDN are beginning to trickle out from vendors, including Alcatel. According to Luc Verbinnen, Alcatel's ADSL product manager, they are priced at a similar rate to existing ADSL modems.
ADSL is more commonly used to provide high speed network access to traditional copper telephone wires. Residential users are able to surf the Net at high speeds and take telephone calls at the same time.
ADSL for ISDN is a new phenomenon and is long awaited in Germany where there is a higher penetration of ISDN among telephony subscribers.
