Chapter 1 Introduction
This chapter introduces functions and structure of the SmartAX
MT880 ADSL terminal (hereinafter referred to as the MT880).
1.1 Functions and Features
The MT880 is a kind of Asymmetric Digital Subscriber Line (ADSL)
terminal. Through the MT880, data, video and audio are transmitted at
high rate in the common telephone line. The features of the MT880 are
shown as follows:
zHigh rate. The maximum downstream transfer rate is 24
Mbit/s; the maximum upstream transfer rate is 1.2 Mbit/s.
zStrong network adaptability. The MT880 can interconnect
with multiple Digital Subscriber Line Access Multiplexes
(DSLAMs)
zStrong maintainablity. The MT880 provides multiple
indicator status, which is convenient to locate failures.
zSimple operation of the configuration and management
page.
