1.3 System Requirements
Before using ZXDSL 831, verify that you meet the following requirements:
· Subscription for ADSL service. Your ADSL service provider should provide you with at least one valid IP address (static assignment or dynamic assignment via dial-up connection).
· One or more computers, each contains an Ethernet 10/100M Base-T network interface card (NIC).
· A hub or switch, if you are connecting the device to more than one computer.
· For system configuration using the supplied web-based program: a web browser such as Internet Explorer v5.0 or later, or Netscape v6.0 or later.
| LED | Color | Function |
| PWR | Green | Power Indicator. On: Power is on, Off: No power |
| DIAG | Green | Self-test indicator. Blinking when the power is turned on and then off |
| LAN | Green | On: LAN link established and active |
| ACT | Green | Blinking: ADSL data activity occurs. May appear solid when data traffic is heavy. |
| DSL | Green | Steady: ADSL link established and active |
| Port | Function |
| DSL | Connects the device to an ADSL telephone jack or splitter using a RJ-11 telephone line |
| LAN | Connects the device to your PC's Ethernet port, or to the uplink port on your hub/switch, using a RJ-45 cable |
| RESET | Reset to factory defaults. To restore factory defaults, keep the device powered on and push a paper clip into the hole. Press down the button for 3 times and then release. |

| Switches the unit on and off |
| PWR | Connects to the supplied power adapter |
This Quick Installation describes how to connect the ZXDSL 831 device to your computer, LAN and the Internet.
This Quick Installation assumes you have subscribed to an ISP for ADSL service and only covers the basic configurations to be applied to residential or corporate networks.
3.1 Hardware Connection
Recommendation: It is recommended to follow the first example in actual connection!
Note: In the circumstance where the first connection example is not applicable and you choose to use the second example, you should install a MicroFilter on the telephone line (a splitter can never be used to replace the MicroFilter).
Special attention: Installing a telephone directly before the splitter will lead to a failure to connect to the CO side device and the Internet or slow connection speed. If you need to connect a telephone to the telephone line before the splitter, a microfilter is required. (Generally, you can connect only one MicroFilter before the splitter for reducing noise.)
1. Shown as the two examples below, use a Telephone line to connect the DSL
The splitter comes with three connectors as below:
LINE: Connects to a wall phone jack (RJ-11 jack)
MODEM: Connects to the DSL jack of ZXDSL 831
PHONE: Connects to a telephone set
2. Use a straight-through Ethernet cable to connect the LAN
Note: Use a “cross-over” Ethernet cable if the device’s LAN port is to connect to a non-UpLink port of a hub/switch.
3. Connect the power cord to the PWR connector on ZXDSL 831, then plug in the AC power adapter to the AC power outlet, and then press the on-off button.

4 Dial-up Connection
Once the hardware connection is properly done, you can use a dial-up connection software to start dialing to your ISP for Internet connection. The following description uses a PPPoE dial-up software, EnterNet300 v1.60, to serve as an example:
1. Launch EnterNet300 and create a new dial-up connection.
2. Enter the username and password (provided by your ADSL service provider).
3. Click “Connect” to initiate the dialing. Once the connection is established, you are ready to access the Internet.
