1.OVERVIEW

1.1 ABOUT 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. Th e frequ ency 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.

1.3 FEATURES

1、 Support ANSI T1.413 ISSUE 2、 ITU G.992.1 (G.DMT)、ITU G.992.2 (G.LITE)、ITU G992.3、

ITU G992.5

2、 Web-based configuration and monitoring.

3、 Support multiple PVCs.

4、 Routing function.

5、 NAPT、DH CP function.

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 wi th the modem.

5、 Pl ug in th e po wer 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.

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
