PairGain and Texas Instruments Achieve Industry Milestone for
System-Level ADSL Interoperability; G.lite Standards-Based
Solutions Are Successfully Demonstrated
Jump to first matched term
Tustin, Calif.--(BUSINESS WIRE)--Feb. 9, 1999--PairGain(R) Technologies, Inc. (NASDAQ: PAIR) and
Texas Instruments (TI) (NYSE: TXN), the worldwide leader in DSP solutions, announced today a
significant milestone toward industry-wide interoperability of ADSL (asymmetric digital subscriber line)
technology and G.lite, the ADSL variation specifically designed to deliver high-speed remote access to the
consumer marketplace. By successfully completing system-level interoperability testing, PairGain and TI
have shown standards-based solutions for both service providers and consumers. Both companies expect
this milestone to provide additional fuel to the already high market demand for ADSL services worldwide.
Interoperability testing took place during the first quarter and included successful full rate ADSL and G.lite
configurations. PairGain's Avidia(TM) System central office (CO) solution demonstrated interoperability
with TI's TNETD3000P customer premise (CPE) evaluation module (EVM), while PairGain's Megabit
Modems(R) demonstrated compatibility with TI's TNETD3000C CO EVM. ATM (asynchronous transfer
mode) cells were successfully passed over varying loop conditions in accordance with the ANSI T1.413
issue 2 standard. The testing confirmed that robust, high-performance ADSL, as well as sub-rate G.lite
connections could be achieved by implementing different products at each end of the wire. As a result,
PairGain and TI are answering market demands for interoperable, standards-based solutions from multiple
vendors.
The interoperability achieved by the PairGain and TI solutions will help drive applications such as IP voice
calls over the Internet, real-time streaming data, distance learning, video and multimedia to the consumer.
Achieving this milestone opens additional opportunities, because both companies' products can now
interoperate with product offerings from each other's business partners.
"When two industry leaders show interoperability while implementing an emerging technology, there is a
tremendous upside for all involved, from service providers to subscribers," said Kevin Woods, director of
product marketing for PairGain's Megabit Access products. "The early demonstration of ADSL and G.lite
interoperability is key to satisfying the demands of our customers and to the widespread acceptance of
the technology by carriers and consumers alike. Interoperability with TI is indicative of PairGain's
commitment to deliver standards-based ADSL solutions to the masses."
"We have now successfully enabled G.lite interoperability for the first time. As a demonstration of our
commitment to accelerate DSP-based ADSL deployment, we will continue working with our partners and
customers such as Alcatel, Siemens and Ericsson to achieve industry-wide interoperability," said James
Collinge, ADSL Marketing Manager for TI. "As we move ahead, TI will continue to strengthen its portfolio of
robust and fully-interoperable G.lite and full-rate ADSL chipset solutions."
