- In March 2003, STMicroelectronics introduced its "ZipperWire" DMT-VDSL chipset, claiming the ability to deliver an aggregate data rate in excess of 100 Mbps over short copper loops. ST's new ZipperWire chipset, which is designed for both central-office and customer-premises-equipment, integrates a complete Frequency Division Duplex DMT VDSL modem from the line to the ATM interface in just two chips. ZipperWire can be programmed for granular, symmetric and asymmetric data rates from 64kbps to 100Mbps in both directions with a reach of up to 4,500 feet. It supports all of the international VDSL-DMT standards (ITU-T, T1e1.4, ETSI) and is compliant with the 997, 998 and Flex frequency plans. STMicroelectronics also noted that its chipset provides spectral compatibility with ADSL, SDSL, ISDN and strong immunity to both bridged taps and radio frequency interference.
- To date, ST has shipped over 50 million ports of xDSL products.
