Thanks to Scrapps who stars on the Aware thread there is a good reference to Siemens XDSL solutions. Amati and TI are mentioned in it as well as other vendors like Aware for g.lite:

Munich , May 21, 1999
Siemens offers service providers all the broadband
end-to-end xDSL-solutions for the digital
subscriber access
For the trade press
The Siemens Information and Communication
Networks Group offers service providers global
end-to-end solutions for implementing all DSL
technologies. The range of technologies available
includes ADSL, U-ADSL/G.Lite, HDSL and SDSL.
Using systems from Siemens, service providers can
connect subscribers either to the ATM broadband
access system XpressLink D in the local exchange,
or to the digital switching system EWSD, or via the
network access system FastLink. The requisite DSL
technologies and the user products are developed
by Siemens both in their own research laboratories
and in close cooperation with global leaders in this
field such as Infineon, Amati Corp., Aware Inc.,
Efficient Networks Inc. and Texas Instruments Inc.
Cooperation is in areas of joint activities such as
specifications for innovative applications in
hardware and software, development,
manufacturing, product sales and marketing as well
as complete solutions. At the forefront of all the
development work is the task of creating DSL
system solutions tailored to the individual needs of
the service providers and suitable for setting up an
end-to-end DSL infrastructure with the appropriate
services such as teleworking, remote LAN access
and faster Internet access.
Joint ventures for DSL technology exist with:
Amati Communications Corp., San Jose, California,
USA, for joint development of products for
transmitting ATM data via ADSL connections.
Amati develops ADSL end devices and software
which Siemens integrates into ATM systems.
Siemens has been working together with Amati and
Texas Instruments since the end of 1996 on
XpressLink D and ADSL and since end of 1998 they
have integrated G.Lite as a software option in
XpressLink D. Amati was bought up by Texas
Instruments over a year ago but cooperation
between Siemens and TI continues.
Aware Inc., Bedford, Massachusetts, USA, in the
area of U-ADSL/G.Lite technology for rapid
subscriber access to the Internet. Aware supplies
G.lite-compatible DSL system design, software
models and services for optimization at the system
level. G.Lite (U-ADSL) software from Aware is
implemented in the Subscriber Line Module (SLM)
using network access technology - in the EWSD
digital switching system at the interface to the
subscriber.
Efficient Networks Inc., Dallas, USA, for joint
development , manufacturing and sales of
end-to-end solutions for digital subscriber
connections (DSL) with the ATM broadband
access system XpressLink D by service providers
based on ATM technology. Efficient Networks
develops and markets CPE devices with the
SpeedStream DSL product range such as external
Ethernet modems, external USB modems as well as
internal modems and adapters for end users.
Efficient's Speedstream products are used in
XpressLink D and EWSD as subscribers' modems.
Infineon Technologies, a Siemens subsidiary, for
developing innovative semiconductor solutions for
the EWSD system. Infineon is global leader in
semiconductor manufacturing for integration of
interfaces for telecommunications.
Texas Instruments Inc. (TI), Dallas, USA for
developing an integrated subscriber line card for
EWSD local exchanges. EWSD uses a digital signal
processor (DSP) from TI which uses TMS320C6000
technology. The subscriber line card forms a G.Lite
(U-ADSL) interface. Voice communication using
this technology occurs in parallel with data
communication in accordance with the
specifications for G.Lite. The Siemens solution
currently supports two subscriber modems per DSP
(eight subscriber connections with voice and data
communication per card) and enables service
providers to equip their EWSD switching systems
for DSL technology without requiring additional
racks or new cabling in the local exchange. In
addition or alternately, XpressLink D offers the
option of incorporating both ADSL and G.Lite in all
existing networks independent from the existing
narrowband technology. XpressLink D currently
offers the highest integration with two G.Lite or
ADSL subscribers per card with the next version
increasing the number of subscribers to sixteen.
G.Lite implementation from Siemens and TI allows
Internet access without changes to home cabling,
"Plug and Play" and without diplexers (splitter or
network termination, NT) at both connection ends.
Siemens is developing a rapid Internet access for
ISDN subscribers with SDSL for speeds of up to 2.3
Mbit/s in both directions.
Siemens uses its extensive experience in the
technology of voice-data integration to integrate
the various DSL technologies into the broadband
access system XpressLink D as well as into the
EWSD switching system family and the Access
Network System FastLink
XpressLink D from Siemens is a
broadbandconnection system providing broadband
IP and ATM services via ADSL, U-ADSL/G.Lite
and in the future also SDSL and VDSL technology
via copper cable. XpressLink D can be installed in
the local exchange or in a 3GDLC system (Integrated
Narrowband/Broadband Digital Loop Carrier
System), e.g. in FastLink D as an access platform for
comprehensive end-to-end services.
EWSD from Siemens are digital communication
systems which combine the currently separate
networks for voice/ISDN, Internet traffic and
broadband communication. Under the banner
"EWSD Innovations" with its EWSD PowerNode,
EWSD InterNode and EWSD BroadbandNode,
Siemens is developing high performance platforms
for all existing and new communication services
and, with its modern broadband family, is offering a
universal infrastructure for Internet, voice and data.
It supports popular services from voice
communication via the Internet to multimedia
applications via one uniform network access. EWSD
Innovations offers network providers solutions for
rapid and flexible provision of newly-combined
voice/data services. The end customer can be
offered all the services from a single source.
FastLink from Siemens is a modular access system
used for telephony, data networks, city and
corporate networks. FastLink is a universal platform
providing the operator with a uniform system for all
services under the common management system
AccessIntegrator.
All the best,
