[Siemens takes ADSL on roadshow in Europe]
Eric --
I wrote to the media director listed at the bottom of a recent Siemen's press release and got the following reply:
>>>
Dear Mr. Mudge,
please find attached our press release regarding the cooperation with AMATI which shows our strong commitment to ADSL. Besides, at present we are carrying out a roadshow throughout Europe where we show some of our key access solutions to customers including ADSL. This roadshow is very well received.
Best regards,
Guenter Gaugler

The press release is from April, but since it gives a different perspective from Amati's, I'll add it here:

Public Communication Networks (™N)
For the trade press
Munich, 29 April 1997
For the highest speed in the access network:
Siemens, Italtel and Amati Communications agree to co-operate
Siemens AG Public Communication Networks Group (™N) and Italtel, the joint venture of Italian STET and Siemens, have agreed with Amati Communications Corp., San Jose, California, to develop products to transmit ATM data via ADSL connections. ADSL transmits data using existing copper telephone lines at a transmission rate of up to 8 Mbit/s. Data from computer networks, such as the Internet, is received up to 200 times more quickly than with conventional modems
™N and Amati will work together with Italtel on the next generation of ADSL systems, which are necessary for future professional telecommunication applications. These systems will also enable carriers to transmit ATM data directly to individual subscribers via existing copper telephone lines. In addition, Siemens will market Amati ADSL modems and distribution systems.
According to estimates of independent market research bodies, ADSL systems in 2001 will have a world market totaling around DM 9 billion.
Using the ADSL system, computer data is transmitted in a frequency band which does not impair existing telephone connections either in the analog or the digital telephone network. For example, ADSL can simultaneously transmit data up to 125 times more quickly at the same time as the ISDN system on the same copper cables. Moreover, ADSL data traffic places no load on the telephone switching systems since the ADSL data is fed directly into the computer network before the switching system.
Siemens has been keeping telecommunications carriers from Germany, USA, Holland, Brazil and South Africa informed about ADSL and its applications since October 1996. To this end, a demonstration system using Amati technology has been installed and this clearly demonstrated the speed benefits of ADSL compared to analog modems and digital ISDN access.
The Amati Communications Corporation is one of the leading developers of advanced transmission systems based on the so-called DMT technology. Amati has successfully tested its systems in field tests for "video on demand" with carriers in Europe and in the Asia-Pacific area, and is testing high-speed access to the Internet with an operator in the USA. The company is also active in the field of local networks with software and interface systems.
With its EWSD digital switching system, Siemens Public Communication Networks Group provides one of the best-selling systems of its type. More than 300 carriers in 93 countries, using over 130 million ports, are equipped with EWSD systems. For the access network area - the "last mile" in a telecommunications network, Siemens also offers a comprehensive range of products with its Multilink product family. Copper, coaxial, glass fiber cable and radio solutions can be combined in any way with one another. Existing twisted pair copper networks can be extended for the transmission of broadband telecommunication services.
The Siemens and Amati ADSL/ATM technology has already been shown at CeBIT `97 in Hanover. Visitors to the fair were able to use it to retrieve information such as high resolution graphics and video clips in real time from the Internet.
ADSL = Asymmetric Digital Subscriber Line
ATM = Asynchronous Transfer Mode
DMT = Digital Multitone Technology
