ZXDSL 931DII User Manual
Note:
If the first connection is not applicable, please adopt the second connection
method. In the second method, install a MicroFilter on the telephone cable
(as illustrated in Figure 3.3-2, do not use a splitter to replace the MicroFilter).
Install the telephone directly before the splitter installation. Or it will lead to
the ZXDSL 931DII and the central office connection failure, causing
Internet access failure, or results in slow connection speed. If a telephone
set is needed to be added before the splitter,, please add a MicroFilter
before the telephone set. Do not connect several telephones before the splitter
and do not connect several telephones with MicroFilter.
If the MicroFilter is not a standard-configuration device, please separately
purchase it from the operator.
Connection Procedure
1 Power OFF the equipment before all other devices are connected.
2
Connect the network cables: connect the RJ-45 Ethernet cable connector
with the Ethernet interface of the ZXDSL 931 CII. Connect other
terminals to the Ethernet adapter of the user computers or ports of other
network devices.
3
Connect the splitter.
The splitter has three interfaces, which are described as follows:
z
LINE: It is connected with the user telephone cable (RJ-11 interface).
z
MODEM (or VDSL): It is connected with the Line interface of the
ZXDSL 931DII.
z
PHONE (or TEL): It is connected to the phone sets.
z
The installation process is as follows: Connect the Line interface of the
ZXDSL 931DII to the splitter MODEM interface by using the RJ-11
telephone cable. Connect the phone set lines to the splitter PHONE
9
ZXDSL 931DII User Manual
interface. Connect the user telephone cable port to the splitter LINE
interface.
4 Connect the power
Connect one power adapter terminal to the power interface of the ZXDSL
931DII, and the other terminal to the socket on the wall. Then switch ON the
ZXDSL 931DII equipment power.
Checking All Connection Cables
Check all connection cables according to the following steps:
1 Check the VDSL2 cable connection
If the Link LED is ON normally, it indicates that the VDSL2 line is correctly
connected (Generally it takes one to two minutes to perform the VDSL2
connection)
2 Check the computer connection
If both the computer Link LEDs are ON and the ZXDSL 931DII LAN LED
is green, it indicates that the computer and the ZXDSL 931DII equipment
are correctly connected.
3 Check the telephone cable connection
If the received telephone signals are normal and free of noise, it indicates the
telephone cable is correctly connected. Power ON/OFF status of the ZXDSL
931DII will not affect the telephone.

Appendix A FAQs
No.
Problem and Troubleshooting
1
All indicators are OFF when the ZXDSL 931DII equipment is powered ON.
First make sure that you have inserted the power adapter of the ZXDSL 931DII
into a working power socket and that the ZXDSL 931DII has been powered ON
(the switch button is pressed down). If the indicators are still OFF after
confirmation of the above items, may be the hardware is damaged. You may
contact local operators for maintenance. Never dismantle the equipment by
yourself.
2
Will VDSL2 affect the telephone conversation quality? Will making phone
calls cause a slow online rate?
VDSL2 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 online simultaneously.
3
How to properly install telephone extensions or other devices on the VDSL2
line?
It is recommended to connect the VDSL2 splitter to the telephone cable first and
then connect the phone sets to the splitter interfaces. Installing a telephone
directly before the splitter will lead to connection failure between the ZXDSL
931DII and the device at central office side, or an Internet access failure, or a
slow connection speed. Connecting other electronic devices between the user end
and splitter may affect the VDSL2 communications (since VDSL2 has a higher
requirement for the line quality) and furthermore affect the normal operation of
VDSL2. If the phone sets are required to be connected before the splitter, you
should serially connect the MicroFilter before the phone sets (Generally, to
minimize interference, only one MicroFilter can be connected before the
splitter).

Sometimes, the VDSL2 users cannot access to the Internet normally
11
ZXDSL 931DII User Manual
No.
Problem and Troubleshooting
First check whether the ZXDSL 931DII is in the normal state (Check the
indicators according to this user manual). If yes, the computer or application
network may be faulty. This is unrelated with VDSL2. If the VDSL2 MODEM is
abnormal, check the status of indicators one by one to remove the fault.
It is suggested to check the following items before seeking help from operators:
1. The VDSL2 telephone cable connectors are proper.
2. The VDSL2 is away from the power cable and large-power electronic
devices.
3. No telephone extensions and fax machines are connected between the
VDSL2 incoming line and splitter.
4. The splitter has been installed correctly.
5. The VDSL2 MODEM has good heat dissipation ratio.
5
What are reasons for VDSL2 synchronization failure (also referred as link
down or link establishment failure)?
12
ZXDSL 931DII User Manual
No.
Problem and Troubleshooting
If the VDSL2 suddenly fails to be synchronized (link down) during application,
usually the Link indicator on the MODEM will not be ON. It is suggested to
check the following steps one by one:
1. First check the quality of incoming cables and incoming cable connectors.
2. Install the VDSL2 MODEM correctly based on the user guidance. Minimize
the number of taps.
3. Check whether the telephone cables and VDSL2 are in good connection or
whether the telephone cables are normal.
4. Try to disconnect the splitter and directly connect the VDSL2 MODEM to
the incoming user cable end. Ensure the problem is not due to improper
installation or incoming user line quality. If the VDSL2 can be synchronized
again, it means that installation of the incoming user side is improper. Please
reinstall it according to the user guide.
5. If the VDSL2 still fails to be synchronized when the VDSL2 MODEM is
connected to the incoming user 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 operator for maintenance or
replacement.
7. If the problem is due to the end office equipment failure, call the operator to
confirm it.
8. Too long connection cable between the splitter and VDSL2 MODEM may
cause poor anti-interference performance and synchronization difficulty.
Therefore, the connection cable should not be too long.
