Appendix A FAQs
1
All indicators are off after the ZXDSL 831A
equipment is powered on
Ⅱ
First make sure that you have inserted the power adapter of the ZXDSL 831A
into
Ⅱ
a working power socket and that the ZXDSL 831A
has been powered on (the
Ⅱ
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 831A
and
Ⅱ
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 831A
is in
Ⅱ
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.
