Chapter 1  Safety Guidance 
1.1  Safety Check   
Before  installing  the  ZXHN  H108N  ADSL  equipment,  you  must  check  the 
following items.   
1  Electric safety 
- Ensure  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   
- Because  the  running  electric  devices  easily  generate  heat,  please 
ensure  that  these  devices  are  positioned  in  a  well  ventilated 
environment.   
- The devices should be placed on a stable and flat plane.   
- Never expose the equipment to direct sunshine, and never place it on a 
PC case.   
- Keep the equipment away from heat and water.   
- Check  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 
- Read the user manual carefully before using the equipment.   
- Note all Cautions in the user manual and product guide.   
- Never use an accessory unbelonging to the  equipment without  prior 
consent  of  the  manufacture,  because  it  may  cause  fire  or  product 
damage.   

ZXHN H108N User’s Manual                                                           
2 
- Use the power adapter accompanied in the package.   
- Rather than directly connecting phones to the ADSL line, led them out 
from the phone interface of the splitter.   
- Never place any objects on the equipment. 
- Keep the equipment dry, ventilated and rainproof, and clean.   
- Unplug the power and all connection cables in case of thunderstorms, 
to protect the equipment against lightning.   
- Clean the equipment using a soft and dry  cloth rather than liquid or 
atomizers. Power off the equipment before cleansing it.   
- Power off the idle equipment.   
- Keep 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. 
- Do not open the case of the equipment, especially during equipment 
power-on.   
- Before plugging/unplugging the power, make sure that the power is off, 
thus avoiding surge.   
- Be careful when unplugging the power, because the transformer may 
be very hot.   
- Keep 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

4.  Connect Ethernet port of the Gateway  with 10/100BASE-T port of the 
computer using the network cable that comes with the modem. 
5.  Plug in the power cord, and turn on the power. 
If you don’t want Internet services and telephone voice services simultaneously, 
please  just  connect  the  LINE  port  of  the  Gateway  with  the  RJ-11  port  (the 
phone jack) on the wall using a telephone cord. In this case, the splitter is not 
necessary. 
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  ZXHN  H108N,  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:   
-  LINE: Connect the user telephone cable (RJ11 interface). 
-  MODEM (or ADSL): Connect the DSL interface of the ZXHN H108N.   
-  PHONE (or TEL): Connect the phone sets.   
The  installation  process  is  as  follows:  Connect  the  LINE  interface  of  the 
ZXHN H108N to the MODEM(or ADSL) interface of the splitter using the 
RJ-11 telephone cable, connect the phone set lines to the PHONE(or TEL) 
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 POWER interface of the 
ZXHN H108N, and the other terminal to the socket on the wall, and then 
switch on the power of the ZXHN H108N equipment.   
Checking all connection cables 

ZXHN H108N User’s Manual                                                           
10 
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 ZXHN H108N, 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 
ZXHN  H108N  turn  green,  it  indicates  that  the  computer  and  the  ZXHN 
H108N 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 ZXHN H108N is powered on or off.   

11 
Appendix A FAQs   
1 
All indicators are off after the ZXHN H108N equipment is powered on. 
First make sure that you have inserted  the  power adapter of the  ZXHN H108N into a working 
power  socket  and  that  the  ZXHN  H108N  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 
Sometimes, the ADSL users cannot gain access to the Internet normally. 
First check whether the ZXHN H108N 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.   
4 
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.   
5 
What  are  reasons  for  ADSL  synchronization  failure  (also  referred  to  link  down  or  link 
establishment failure)? 

ZXHN H108N User’s Manual                                                           
12 
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. 
6 
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.
