1 Introduction
The GO-DSL-N151 device is an ADSL access device that supports multiple line
modes. With four 10/100Base-T Ethernet interfaces at the user end, it provides
high-speed ADSL broadband connection to the Internet or Intranet for high-end
users such as net cafes and office users. The device provides high performance
access to the Internet with a downlink of 24 Mbps and an uplink of 1 Mbps.
As a WLAN AP or WLAN router, the device supports WLAN access to the
Internet. It complies with the IEEE 802.11b/g/n specifications, WEP, WPA and
WPA2 security specifications.
1.1 Safety Precautions
Take the following instructions to prevent the device from risks and damage
caused by fire or electric power:
Use the type of power marked by the volume label.
Use the power adapter packed in the device package.
Pay attention to the power load of the outlet or prolonged lines. An
overburden power outlet or damaged lines and plugs may cause electric
shock or fire accident. Check the power cords regularly. If you find any
damage, replace it at once.
Proper space left for heat dissipation is necessary to avoid damage
caused by overheating to the device. The long and thin holes on the device
are designed for heat dissipation to ensure that the device works normally.
Do not cover these heat dissipation holes.
Do not put this device close to a place where a heat source exists or high
temperature occurs. Avoid the device from direct sunshine.
Do not put this device close to a place where it is overdamp or watery. Do
not spill any fluid on this device.
Do not connect this device to any PCs or electronic products, unless our
customer engineer or your broadband provider instructs you to do this,
because any wrong connection may cause power or fire risk.
Do not place this device on an unstable surface or support.

2 Hardware Installation
Step 1 Connect the DSL interface of the device and the Modem interface of
the splitter through a telephone cable. Connect the phone to the
Phone interface of the splitter through a cable. Connect the incoming
line to the Line interface of the splitter.
The splitter has three interfaces:
Line: Connect to a wall phone jack (RJ-11 jack).
Modem: Connect to the ADSL jack of the device.
Phone: Connect to a telephone set.
Step 2 Connect the LAN interface of the device to the network card of the PC
through an Ethernet cable (MDI/MDIX).
Note:
Use twisted-pair cables to connect with the hub or switch.
Step 3 Plug one end of the power adapter to the wall outlet and connect the
other end to the Power interface of the device.
Connection 1
Figure 1 shows the application diagram for the connection of the router, PC,
splitter and the telephone sets, when no telephone set is placed before the
splitter.

Note:
When connection 2 is used, the filter must be installed close to the telephone
cable. See Figure2. Do not use the splitter to replace the filter.
Installing a telephone directly before the splitter may lead to failure of
connection between the device and the central office or failure of Internet
access or slow connection speed. If you really need to add a telephone set
before the splitter, you must add a microfilter before a telephone set. Do not
connect several telephones before the splitter or connect several telephones
with the microfilter.
