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.
1.2 Hardware Configuration
This section mainly introduces the appearance and structure of
the MT880.

Note:
Figures of the front panel and the rear panel are only for your
reference.
1.2.1 Front Panel
Figure 1-1 shows the front panel of the MT880.
Figure 1-1 Front panel of the MT880
Table 1-1 shows descriptions of indicators of the MT880 in the
front panel.
Table 1-1 Indicator descriptions
Indicator Color Status Description
Green On The MT880 is powered on.
Power Green Off The MT880 is powered off.
Green Blinking The MT880 is being activated.
Green On The MT880 is activated.
Orange Blinking The built-in PPP dial-up software
is dialing.
Orange On
The built-in PPP dial-up software
succeeds in dialing.
ADSL LINK
Orange/Green Off
The telephone line is not
connected or the next activation is
being prepared.

Indicator Color Status Description
Green Blinking There is traffic over the ADSL
interface.
ADSL ACT
Green Off
No data is transmitted through the
ADSL interface.
Green On
The Ethernet interface is normally
connected and the data is
transmitted at 10 Mbit/s.
Orange On
The Ethernet interface is normally
connected and the data is
transmitted at 100 Mbit/s.
LAN LINK
Orange/Green Off The Ethernet interface is not
connected with the network cable.
Green Blinking There is traffic over the Ethernet
interface.
LAN ACT
Green Off
No data is transmitted through the
Ethernet interface.
Note:
PPP = Point-to-Point Protocol
Note:
If the MT880 fails to be activated, it tries again after an interval. In such
an interval (about 1 minite), the ADSL LINK indicator is off.
1.2.2 Rear Panel
Figure 1-2 shows the rear panel of the MT880.

Figure 1-2 Rear panel of the MT880
Table 1-2 shows descriptions of interfaces and buttons of the
MT880 in the rear panel.
Table 1-2 Descriptions of Interfaces and Buttons
Interface/Button Description
ADSL It is used to connect with the Modem interface of a
splitter.
Ethernet It is used to connect with a computer or a switch.
Reset
It is used to restore the default settings of the MT880.
Once you use this function, all your customized
settings will be lost. Therefore, be careful with it.
Power It is used to power on/off the MT880.
12V AC 0.8A It is used to connect with the power adapter.
1.2.3 Splitter
The external splitter can efficiently reduces the signal disturbance
on the telephone line. When voice and data are transmitted on the
same telephone line at the same time, you need to use the external
splitter to separate the voice and data signals:
zLINE: Connecting to the phone jack on the wall.
zPHONE: Connecting to the telephone.
zMODEM: Connecting to the ADSL interface of the MT880.
