ST70135

The ST70135 is designed as one kind of ASCOT ADSL modem chip device that can be used in (1)high speed internet access; (2)remote access to corporate network for telecommuters and branch offices; (3)video-on-demand over twisted pair; (4)CPE ADSL modems, and routers; (5)ADSL PC NIC's; (6)G. LITE CPE splitterless applications. Also this device can easily be hooked up with ATM systems through the built-in UTOPIA level 2/1 interface.

Features of the ST70135 are:(1)COMPLETE CHIP SET FOR ADSL CPE MODEM; (2)COMPLIANCE WITH ANSI T1.413 ISSUE 1 & ISSUE 2; (3)compliance with g.992.1 (full rate) & G.992.2 (G. lite); (4)implements discrete multitone (DMT) modulation and demodulation on cpe side; (5)data rates up to 8mbps downstream and to 1mbps upstream with 32kbps granularity; (6)built-in atm transport; (7)support adaptive rate mode in 32Mbps increments; (8)255/128 carriers with 4.3125 KHz spacing; (9)dedicatedsoftware driveravailable; (10)processor independent c++ source compilation; (11)frequency division multiplexing (FDM) for high robustness in presence of crosstalk; (12)reed-solomon forward error correction; (13)trellis coder and decoder; (14)programmable simultaneous support of interleaved and non-interleaved channels (dual latency); (15)full, reduced and minimal atm overhead framing modes; (16)bit stream mode capablity for stm transport; (17)direct connection to atm systems via utopia interface (level 1 or 2).
