MUNICH -- Infineon Technologies AG today announced plans to introduced a new chip-set series for 4-band very-high-bit rate digital subscriber line (VDSL) networks with support for asynchronous transfer mode (ATM) and packet-over-VDSL communications.
With the availability to supporting either ATM or packet-over-VDSL, the new chip sets will enable telecom equipment makers to produce broadband systems with the highest possible broadband transmission rates for copper phone lines, Infineon said. These high-speed transmission rates will support digital subscriber line multiplexers (DSLAMs), switches, and customer premise equipment (CPE), said the Munich chip maker.
The new 4-band VDSL chip series will be formally introduced at FS-VDSL meeting in Denver (hosted by the Full Service-VDSL Committee) next week, March 4-6.
"Telecommunications companies have been eagerly seeking a true, broadband over copper solution to meet market demand for a 'triple play' of integrated fast Internet access, video with high quality streaming media, and voice services delivered over the same copper wire," said Christian Wolff, vice president and general manager of Infineon's Access Business Unit.
"The new 4-Band VDSL family signifies a technological breakthrough, being the first commercially available standards compliant VDSL solution as well as the first to support both ATM and Packet over VDSL functionalities," he said.
The 4-band VDSL chip sets incorporate Infineon's 10BaseS Ethernet-over-VDSL technology and support for packet-over-VDSL. The chip set series is "a major step in the adoption of Ethernet in the local copper loop," Wolff said.
The chip sets feature "all-in-one" circuitry including embedded interleaver memory, microprocessor, anti-aliasing filters, gain amplifier, DCXO, ADC and DAC, said Infineon. Two initial members in the chip set series will support fast and slow channels, sleep and wake up modes, power back off, blind acquisition and channel equalization. The 4bVDSL and PoVDSL have an integrated controller and flexible software, allowing for operation of the modem as a stand-alone VDSL physical-layer (PHY), Infineon said.
The 4bVDSL ATM-based chip set features a dual-latency UTOPIA interface as well as a built-in PCM interface -- and is able to transport up to four E1/T1/J1 lines using the same twisted pair.
The PoVDSL (packet-over-VDSL) chip set features an MII interface (IEEE 802.3) supporting PTM-TC (HDLC) as per ITU-T G.993.1 standard definition. A PCM transport is in parallel to PTM traffic.
Engineering samples of Infineon's 4-Band VDSL chip set series will be available at the start of the second quarter of 2002. Pricing was not released.
