Can I use my modem during thunderstorm ?
ADSL modems can be damaged by thunderstorms. Our product
warranty does not apply to damage caused by lightning. If your area
is frequent in thunderstorms, you are advised to use a surge protector.
Certain surge protectors have been reported to reduce download speed,
so you are advised to test your speed before and after installation to
make sure that it adds no problems to your line.
Do I need to install additional telephone lines in order to use ADSL?
No, you do not need to do so. ADSL and standard voice telephones
operate on a different set of frequencies. The difference in frequencies
allows both IP (Internet) traffic and voice traffic to co-exist on a same
physical phone line.
Will my old PC be fast enough for ADSL?
Yes. But if you start to use the ADSL line to view video-on-demand or
other memory- and processor-hungry functions, you may well decide
that your PC is too slow. However, there are still many sites that can
be accessed by slower PCs.
How can I send/receive fax as well as surf the Internet at the same
time ?
To send/receive fax, you may connect your fax machine to the
PHONE
jack of your modem (same as the way you connect to the telephone
set as illustrated in
Chapter 3 - Connecting DSL258E
).
Do I need to use an ISDN splitter when using ADSL ?
Your modem may or may not have a built-in ISDN splitter at the
PHONE jack. Check with your Internet Service Provider.
However
, if you are sharing the ADSL line with other telephone line
extensions, you will need to have an ISDN splitter connected between
the other telephone set and the telephone wall socket connecting to it.
