1.OVERVIEW
1.1ABOUT ADSL
An ADSL MODEM is a broadband Internet access device，which utilizes the high frequency segment of
the phone line to transmit high-speed data without affecting the voice transmission. The frequency of the ADSL
signal is higher than that of voice, so voice and ADSL signal can coexist in one line by using a splitter to
insulate each from the other. ADSL data transfer adapts the asymmetry model. It supports upload transmission
speed up to 1Mbps and download speed up to 8 Mbps (24Mbps for ADSL2+). ADSL is an ideal device for
broadband access.
1.2 ABOUT ADSL2/2+
Transmission performance of ADSL2 is improved comparing with the first generation of ADSL. These
improvements are mainly concerned with long distance, anti-line-loss, anti-noise, etc. By doubling the
transmission bandwidth, ADSL2+ has implemented a downlink rate as high as 24 Mbps. Therefore, Internet
applications such as synchronous transmission of multi video stream, online games and huge capacity of
downloading files are made possible.
1.3FEATURES
1、Support ANSI T1.413 ISSUE 2、ITU G.992.1 (G.DMT)、ITU G.992.2 (G.LITE).
2、Web-based configuration and monitoring.
3、Support up to 4 PVCs.
4、Routing function.
5、NAPT、DHCP function.
6、Maximum downstream transmission rates of 8 Mbps（24Mbps for ADSL2+）。
7、Maximum upstream transmission rates of 1Mbps
8、Transmission distance up to 5.5 km.

Introduction：
1、Use a telephone cord to connect the LINE port of the splitter with the RJ-11 port (the phone jack) on
the wall.
2、Use another telephone cord to connect the ADSL port of the splitter with the LINE port of the ADSL
Modem.
3、Use another telephone cord to connect the telephone set with the PHONE port of the splitter.
4、Connect Ethernet port of the ADSL MODEM with 10/100BASE-T port of the computer using the
network cable that comes with the modem.
5、Plug in the power cord, and turn on the power.
If you do not want Internet services and telephone voice services simultaneously, please just connect the
LINE port of the ADSL Modem with the RJ-11 port (the phone jack) on the wall using a telephone cord. In this
case, the splitter is not necessary.

3.CONFIGURATION
3.1 DEFAULT CONFIGURATION
ADSL MODEM has pre-configured with the following VCI/VPI. The default dial-up mode is bridge
encapsulation. For bridge mode, no need to configure any more parameter. However, the third party dial-up
software is needed for connection with the Internet
Tabel 3.1
Link Name VCI VPI
pvc_0_32 0 32
pvc_8_35 8 35
pvc_0_35 0 35
pvc_8_81 8 81
3.2 COMPUTER CONFIGURATION
The default IP address for ADSL MODEM is: 192.168.1.1; The Subnet Mask is：255.255.255.0. Users can
configure ADSL MODEM through an Internet browser. ADSL MODEM can be used as gateway and DNS
server; users need to set the computer’s TCP/IP protocol as follow:
1、Set the computer IP address at same segment of ADSL MODEM，such as set the IP address of the
network card to one of the “192.168.1.2”～“192.168.1.254”.
2、Set the computer’s gateway the same IP address as the ADSL Modem’s.
3、Set computer’s DNS server the same as ADSL Modem’s IP address or that of an effective DNS server.
3.3 ADSL MODEM CONFIGURATION
3.3.1 LOG IN
Open the browser; input http://192.168.1.1 at the address column. Press “Enter” key then the entry dialog
box will show up as Figure 3.1. Input “username” and “password” (capital sensitive), then press Enter.
