Chapter 1 Safety Guidance
1.1 Safety Check
Before installing the ZXDSL 831A ADSLⅡequipment, you must check the
following items.
1 Electric safety
zEnsure that there are no inflammable, conductive or moist objects
around. Check whether the cables are aged and whether other
electrical appliances are placed stably.
2 Equipment position
zBecause the running electric devices easily generate heat, please
ensure that these devices are positioned in a well ventilated
environment.
zThe devices should be placed on a stable and flat plane.
zNever expose the equipment to direct sunshine, and never place it on a
PC case.
zKeep the equipment away from heat and water.
zCheck whether power supply is available. The input voltage
fluctuation range must be less than 10%. The power plug should not
share one socket with a hair drier, iron or refrigerator.
1.2 Safety Cautions
zRead the user manual carefully before using the equipment.
zNote all Cautions in the user manual and product guide.
zNever use an accessory unbelonging to the equipment without prior
consent of the manufacture, because it may cause fire or product
damage.

ZXDSL 831AⅡUser’sManual

zUse the power adapter accompanied in the package.
zRather than directly connecting phones to the ADSL line, led them out
from the phone interface of the splitter.
zNever place any objects on the equipment.
zKeep the equipment dry, ventilated and rainproof, and clean.
zUnplug the power and all connection cables in case of thunderstorms,
to protect the equipment against lightning.
zClean the equipment using a soft and dry cloth rather than liquid or
atomizers. Power off the equipment before cleansing it.
zPower off the idle equipment.
zKeep the ventilation hole clean and prevent any objects from dropping
into the equipment through it. Otherwise, it may cause short circuit
and further cause equipment damage and fire. Do not spray liquid on
the surface of the equipment.
zDo not open the case of the equipment, especially during equipment
power-on.
zBefore plugging/unplugging the power, make sure that the power is off,
thus avoiding surge.
zBe careful when unplugging the power, because the transformer may
be very hot.
zKeep the equipment and all its parts and accessories out of children’s
reach.
Note:
Please read the above safety guidance carefully before equipment use. Users
should assume responsibilities for any accidents due to incompliance with the
above instructions .

Connection 1
The following connection method is recommended.
Figure 3.2-1 shows the connection between a ZXDSL 831A , computer,Ⅱ
splitter and telephones.
Figure 3.2-1 ZXDSL 831A Connection Schematic Diagram (No Phone sets are Installed Before theⅡ
Splitter)
Connection 2
Figure 3.2-2 shows the connection when the splitter is installed near the
ZXDSL 831A .Ⅱ

ZXDSL 831AⅡUser’s Manual

Figure 3.2-2 ZXDSL 831A Connection Schematic Diagram (Phone sets are Installed Before the Splitter)Ⅱ
Note:
In the circumstance where the first connection example is not applicable and
you choose to use the second example, you must install a MicroFilter on the
telephone cable (as illustrated in Figure 3.3-2, do not use a splitter to replace
the MicroFilter).
Installing a telephone directly before the splitter will lead to a failure of
connection between the ZXDSL 831A andⅡthe device at central office side,
or a failure of access into the Internet, or a slow connection speed. If you really
need to add a telephone set before the splitter, you have to add a MicroFilter
before the telephone set. Do not connect several telephones before the splitter.
Moreover, do not connect several telephones with MicroFilters.
The filter is not a standard-configuration device and you should separately
purchase it from the operator.
Connection procedures
1 Power off the equipment before all the other devices are connected.
2 Connect the network cables: Insert the RJ-45 Ethernet cable connector
into the Ethernet interface of the ZXDSL 831A , and connect its otherⅡ

ZXDSL 831AⅡUser’sManual

terminal to the Ethernet adapter of the customer computers or ports of other
network devices.
3 Connect the plug of the USB cable into the USB port of the ZXDSL
831AⅡ, connect the other end of the USB cable to the USB port of the PC.
4 Connect the splitter
The splitter has three interfaces, which are described as follows:
zLINE: Connect the user telephone cable (RJ11 interface).
zMODEM (or ADSL): Connect the DSL interface of the ZXDSL 831A .Ⅱ
zPHONE (or TEL): Connect the phone sets.
The installation process is as follows: Connect the DSL interface of the
ZXDSL 831AⅡto the MODEM interface of the splitter using the RJ-11
telephone cable, connect the phone set lines to the PHONE interface of the
splitter, and then connect the user telephone cable port to the LINE interface
of the splitter.
5 Connect the power
Connect one terminal of the power adapter to the PWR interface of the
ZXDSL 831A , and the other terminal to the socket on the wall, and thenⅡ
switch on the power of the ZXDSL 831A equipment.Ⅱ
Checking all connection cables
Check all connection cables following the below procedure.
1 Check the ADSL cable connection
If the DSL LED is on upon power-on of the ZXDSL 831A ,Ⅱit indicates
that the ADSL line is correctly connected (Generally it takes one to two
minutes to perform the ADSL connection).
2 Check the computer connection
If both the LINK LED on the computer adapter and the Ethernet LED of the
ZXDSL 831A turn green,Ⅱit indicates that the computer and the ZXDSL
831A equipment are correctly connected.Ⅱ
3 Check the telephone cable connection

ZXDSL 831AⅡUser’s Manual
11
The telephone cable is correctly connected if the received telephone signals
are normal and free of noise. And the telephone will not be affected no
matter whether the ZXDSL 831A isⅡpowered on or off.

Chapter 4 Install USB Driver
If you want the ZXDSL 831A to be connected with a PC throughⅡthe USB
interface, you need to install the USB driver first. Read a certain section below
pertinent to your operating system. If you have already installed the driver,
skip this chapter.
ZXDSL 831AⅡis a device with both Ethernet Interface and USB Interface,
which is independent, you may use either of them to connect to the different
computers, in this way the two computers can connect to the network at one
time. ZXDSL 831AⅡcan be seen as a simple two-port HUB. So, do not
connect both the Ethernet Interface and USB Interface to a same computer.
When using USB Interface, you must install the drivers. After installation, a
virtual network card, "ZTE USB Remote NDIS Device", will be added into the
computer. It has all the functions of a real network card, and it makes
installation more easily
