The factors affecting the wireless network coverage range include the location
of the product, distance between the product and a wireless terminal, number of
obstacles, obstacle material and density, and interference source. It is
recommended that you place the product in accordance with the following
principles to maximize the strength of wireless signals.
The product should be far away from the objects affecting wireless signal
propagation, for example, an object with a high reflectivity such as a metallic
object or a mirror.
The product should be far away fr om an electrical appliance with a strong
magnetic or electric field, for ex ampl e, a mic rowav e ove n, a ref riger ator, a
wireless router, a cordless phone, or a Bluetooth product.
The product should be installed on the same floor as the appli ed ar ea.
Do not put other objects on the product. Try to reduce the number of
obstacles between the product and a wireless terminal. Horizontally place
the product in the middle of the applied area and do not put it in a corner.
Do not place the product at a high position while it is placed horizontally. The
recommended height is 1.2 to 1.5 meters.
4 Troubleshooting
All indicators are OF F when the ZXHN H168N equipment is powered
ON.
First make sure that you have i nserted the power adapter of the ZXHN
H168N into a working power socket and that the Z XHN H168N has been
powered ON (the switch button is pressed down). If the indicators are still
OFF after confirmation of the above item s, may be t he hardware is damaged.
You may contact local operators for maintenance. Never dismantle the
equipment by yourself.
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. Neit her the access rate nor conv ersation qualit y
will fall even if you are in a call and online simultaneously .
How to properly install telephone extensions or other devices on the
VDSL2 line?
It is recommended to connect t he VDSL2 splitter to the telephone cabl e first
and then connect the phone sets to the splitter interfaces. Installing a
telephone directly before the splitt er will lead to connection failure between
the ZXHN H168N 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 li ne quality) and furthermore
affect the normal operation of VDSL2. If the phone set s are required to be
connected before the splitter, you should seriall y 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
First check whether the ZXHN H168N is in the normal state (Check the
indicators according to thi s user manual). If yes, the comput er or applic ation
network may be faulty. This is unrelated with VDSL2. If the ZXHN H168N 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:
i. The VDSL2 telephone cable connectors are proper.
ii. The VDSL2 is away from the power cable and large-power elect ronic
devices.
iii. No telephone extensions and fax mac hines are connected between th e
VDSL2 incoming line and splitter.
iv. The splitter has been installed correc tly.
v. The ZXHN H168N has good heat dissipation ratio.
What are reasons for VDSL2 synchronization failure (also referred as
link down or link establishment failure)?
If the VDSL2 suddenly fails to be synchronized (link down) during application,
usually the Link indicator on the ZXHN H168N will not be ON. It is suggested
to check the following steps one by one:
i. First check the quality of incoming cables and incoming cable connectors.
ii. Install the ZXHN H168N correctly based on the user gui dance. M inimi ze
the number of taps.
iii. Check whether the telephone cables and VDSL2 are in good connection
or whether the t elephone cables are normal.
iv. Try to disconnect the splitter and directly c onnect the ZXHN H168N 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 install ation of the incoming user side is improper.
Please reinstall it according to the user gui de.
v. If the VDSL2 still fails to be synchronized when the ZXHN H168N is
connected to the incoming user cable end, contact the operators to check
whether it is due to external line failure or ZXHN H168N failure.
vi. If the splitter problem is determined, call the operator for maintenance or
replacement.
vii. If the problem is due to the end office equipment failure, call the
operator to confirm it.
viii. Too long connection cabl e between the spli tt er and ZXHN H168N may
cause poor anti-interference perf ormance and synchronization difficulty.
Therefore, the connection cable should not be too long.
