DESCRIPTION
ST70137 is STMicroelectronics UNICORN
chipset ADSL DMT transceiver for controllerless
ADSL CPE modem.
UNICORNTMallows to develop easily and quickly
low cost ADSL CPE modem for PC environment.
UNICORNTMis made of two devices, ST70137
and ST70136 or ST70134 (CPE ADSL Analog
Front End). ST70137 provides PCI and USB
interface. PCI is used to build ADSL CPE modem
bundled in the PC, USB interface is used to build
external bus powered ADSL modem.
ST70137 is compliant with ITU 992.1 Annexe A
and B, with ITU 992.2 and with ANSI T1.413.
UNICORNTMchipset is delivered with a complete
PC software suite for Microsoft Windows 98,
Windows 2000 and Windows NT. NDIS5.0 PCI
driver and USB driver with ADSL modem control
and ATM device driver are provided assuring full
ATM support. Configuration and diagnostic tools
are also provided.
UNICORNTMchipset and PC software ensure
interoperability with the most deployed DSLAM.
