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.

4 Connect the power

Connect one terminal of the power adapter to the PWR interface of the

ZXDSL 831/831B/831II/831BII, and the other terminal to the socket on the

wall, and then switch on the power of the ZXDSL 831/831B/831II/831BII

equipment.

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 831/831B/831II/831BII,

it 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 831/831B/831II/831BII turn green, it indicates that the computer

and the ZXDSL 831/831B/831II/831BII equipment are correctly connected.

3

Check the telephone cable connection

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 831/831B/831II/831BII is powered on or off.

Appendix A FAQs

1

All indicators are off after the ZXDSL 831/831B/831II/831BII equipment is

powered on

First make sure that you have inserted the power adapter of the ZXDSL

831/831B/831II/831BII into a working power socket and that the ZXDSL

831/831B/831II/831BII has been powered on (the switch button is pressed down). If

the indicators are still off after confirmation of the above items, the hardware is

damaged probably. You may contact local operators for maintenance. Never

dismantle the equipment by yourself.

2

Will ADSL affect the telephone conversation quality? Will making phone calls

cause a slow online rate?

ADSL separates voices from data through the frequency division multiplexing

technology. Therefore, voices and data run in different paths without mutual

interference. Neither the access rate nor conversation quality will fall even if you are

in a call and on line simultaneously.

3

How to properly install telephone extensions or other devices on the ADSL line?

It is recommended to first connect the ADSL splitter to the incoming customer end of

the telephone cable, and then connect the phone sets to the splitter interfaces.

Installing a telephone directly before the splitter will lead to a failure of connection

between the ZXDSL 831/831B/831II/831BII and the device at central office side, or

a failure of access into the Internet, or a slow connection speed.Connecting some

other electronic devices between the incoming customer end and splitter may affect

the ADSL communications (since ADSL has a higher requirement for the line

quality) and furthermore affect the normal operation of ADSL. If the phone sets are

required to be connected before the splitter, you should serially connect the filter

MicroFilter before the phone sets (Generally, to minimize interference, only one

filter MicroFilter can be hang before the splitter).

4

Sometimes, the ADSL users cannot gain access to the Internet normally

First check whether the ZXDSL 831/831B/831II/831BII is in the normal state

(Check the indicators with this user manual). If yes, the computer or application

network may be faulty, which is unrelated with ADSL. If the ADSL Modem is

abnormal, check the status of indicators one by one to remove the fault.

You are suggested to first make sure the following items before seeking help from

operators: 1. The ADSL telephone cable connectors are proper; 2. The ADSL is away

from the power cable and large-power electronic devices; 3. No telephone extensions

and fax machines are installed between the ADSL incoming line and splitter; 4. The

splitter has been correctly installed; 5. The ADSL MODEM is of good heat

dissipation.

Password verification failure

MODEM synchronization and connection are normal. However, sometimes the

password fails to be verified.

1. Note that the account and password are case sensitive and some accounts contain a

domain name.

2. Virtual dialup software. It is possible that sometimes the virtual dialup software is

faulty, or conflict with other software in the operating system. At this time, you are

suggested to reinstall the dialup software or replace it with other software.

3. Network adapter drive program problem.

4. In arrears of fees. Pay the fee timely in this case.

6

What are reasons for ADSL synchronization failure (also referred to link down

or link establishment failure)?

If the ADSL suddenly fails to be synchronized (link down) during application,

usually the DSL indicator of the MODEM will not be solid on. You are suggested for

checkup in the following sequence:

1. First check the quality of incoming cables and incoming cable connectors.

2. Install the ADSL Modem correctly based on the user guide, to minimize the

number of taps.

3. Check whether the telephone cables and ADSL are in good contact or whether the

telephone cables are normal.

4. Try to disconnect the splitter and directly connect the ADSL Modem to the

incoming customer cable end to ensure that the problem is not due to improper

installation or incoming customer line quality. If the ADSL can be synchronized

again, it means that installation of the incoming customer part is improper. Please

reinstall it according to the user guide.

5. If the ADSL still fails to be synchronized after the ADSL Modem has been

connected to the incoming customer cable end, contact the operators to check

whether it is due to external line failure or Modem failure.

6. If the splitter problem is determined, call the operators for maintenance or

replacement.

7. The problem may be also due to the end office equipment fault of the operator.

Call the operator to confirm it.

8. Too long connection cable between the splitter and ADSL Modem may cause poor

anti-interference

performance

and

synchronization

difficulty.

Therefore,

the

connection cable should not be too long.

The authenticated user names and passwords cannot be re-authenticated?

This problem may be due to the following reasons:

1. Your account

has expired or you are a defaulting subscriber (please pay the

deficit sum).

2. You move into a new area. Because the account and the path PVC are bundled by

some operators, your previous account and password cannot be authenticated after

you changed your path.

3. One of your accounts has logged on successfullyTherefore, you will fail to be

re-authenticated because the operator has recognized the uniqueness of this account

4. Maybe you failed to deregister your account timely in the Broadband Access

Server (BAS) when you were off line abnormally, so the BAS or the billing system

deemed that your account was still available. Therefore, your re-login may fail

because of uniqueness of your account You are suggested to redial up later. If still

failing, contact the operator for a solution.
