ADSL
is a technology that enables users to obtain high-speed access
to the Internet. It uses your existing copper phone line without
purchasing an additional line.
| But
How Does It Really Work ? |
ADSL
separates voice signals from high-speed data signals on the same
copper wire. It splits the analog signal into different frequency
bands. Standard voice signals travels at a low frequency through
the core (center) of the copper phone lines. The data signal is
transmitted at a much higher frequency and travels on the surface
of the copper phone lines. This technology allows users to make
voice calls while maintaining an online data connection. The data
signal does not to interfere with the voice or Custom-Calling
features that may be on the line. Because ZIBNUS Internet ADSL
service uses the existing wire pair that is distinct for each
location, we have what is called a PVC (Private Virtual Connection)
link to the Internet. This provides greater security for the customer’s
files and promotes much more consistent speed; both receiving
(downstream) and sending (upstream).
| It
Works on My Existing Phone Line ? |
Voice
signals travel over wire in an analog (continuous wave) form.
Data travels in a digital (on/off pulse) form. ADSL uses these
differences to maximize transmission capabilities over the copper
wire. Analog voice signals are carried at low frequencies inside
the copper wire. Digital data signals utilize the higher frequency
capability on the outside of the wire.
| Do
I get more Data through a Cable Modem Line than a Telephone
Line ? |
No.
Cable Internet services have to provide more 'available' bandwidth
because their subscribers share it with all of your neighbors.
Though 'available' in theory, the reality is often different.
