UTOPIA (ATM) ADSL Modem Solution
The MTK-20150 is a complete ADSL modem solution consisting of an integrated
Analog Front-End (MTC-20154) and a DMT Modem and ATM Framer with
embedded ADSL Tranceiver Controller and Modem control interface (MTC-20156),
integrating the DMT/ATM digital modem and a dedicated ADSL Transceiver Controller
with associated firmware.
The MTK-20150 therefore provides all the active functions required to implement
a complete ATM-based, rate adaptive DMT ADSL modem.
The data interface is implemented as an ATM Utopia interface. A HW/FW
command and control interface (CTRLE), to communicate with external management
entities, is directly provided, without need for glue logic.
The chipset employs Discrete Multitone modulation as specified in ANSI T1.413.
It also complies with ITU G-dmt and G-Lite standards. Additional Reed Solomon
forward error correction with or without interleaving provides maximum noise
