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 831/831B/831II/831BII and the 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 831/831B/831II/831BII, and
connect its other terminal to the Ethernet adapter of the customer computers
or ports of other network devices.
3 Connect the splitter
The splitter has three interfaces, which are described as follows:
z LINE: Connect the user telephone cable (RJ11 interface).
z MODEM (or ADSL): Connect the DSL interface of the ZXDSL
831/831B/831II/831BII.
z PHONE (or TEL): Connect the phone sets.
The installation process is as follows: Connect the DSL interface of the
ZXDSL 831/831B/831II/831BII to the MODEM interface of the splitter
ZXDSL 831/831B/831II/831BII User’s Manual

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.

5 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.

7 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 successfully. Therefore, 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.
