Looking to expand its Digital Subscriber Line (DSL) chip business into the consumer space, Siemens has licensed the discrete
multitone (DMT) coding technology from Aware Inc., Bedford, Mass.
Siemens will leverage this DMT technology in order to bring out a new
line of chipsets for central-office and modem applications based on the
emerging G.Lite standard, a DSL-based protocol that promises to deliver
data at speeds of up to 1.5-Mbit/s downstream and 384-Kbit/s upstream.
Siemens will disclose more details about its G.Lite-based chipset in
the near future, but the product will basically combine Aware's
"splitterless" DSL-Lite coding technology for use in high-speed data
transmission. Siemens' chipset will also consist of its own,
digital-signal processor technology, dubbed Carmel.
Siemens' solution will be among the first to combine voice and data
services on a chipset, thereby eliminating the ``splitter'' equipment.
Aware's DSL-Lite technology delivers data transmission speeds of up to
1.5-Mbit/s downstream and up to 512-Kbit/s upstream at distances of up
to 24,000 feet.
Siemens will demonstrate its chipset for central-office applications by
The deal could propel Siemens into a leadership role in the DSL market.
In addition to its upcoming G.Lite solution, the German chip giant has a
chipset for the another DSL market, high-bit-rate DSL or HDSL, a
technology that transmits data at 1.544-Mbit/s over two pairs of copper
It is also a major boost for Aware, which has also licensed its DMT
technology to 3Com, Analog Devices Inc., and the Microelectronics Group
of Lucent Technologies Inc. "Based on the massive, installed base of
existing Siemens line-card, chipsets in more than 120 countries, we see
an enormous upgrade opportunity with this new solution, " said Michael
Tzannes, president and chief executive officer of Aware.
