| Next to existing Plain Old
Telephone Service (POTS) signals, ADSL signals are added to
the wires in the DataStream NOC. Although POTS and ADSL occupy
distinct channels, they might influence one another. Telephone
devices can possibly experience audible disruption whilst ADSL
signals can experience interference resulting in throughput
deterioration. |
| |
| To avoid this mutual
interference, an electronic central splitter or distributed
filter is required. A splitter splits or combines signals
while a filter prevents signals from entering or escaping from
devices. |
| |
| Central Splitter |
| |
| In the configuration below the
public telephone line terminates into a splitter. |
| |
 |
| Depending upon the existing
wiring and sockets, ADSL should now be present on all of your
wall sockets. In case of a new dedicated cable, ADSL service
is only present on those wall sockets attached to this
cable. |
| |
| |
| Distributed
Filters |
| |
| In this configuration, the
combined POTS/ADSL signals are distributed over the complete
in-house wiring. If your wall sockets are fully wired you can
connect your modem to any wall outlet supporting POTS
services. |
| |
 |
| |
| For optimum ADSL performance
and for telephony device protection from ADSL signals, filters
are to be inserted in front of any connected telephony device
inside your house. |
