Asymmetric Digital Subscriber Line (ADSL) is a form of
DSL, a data communications technology that enables
faster data transmission over copper telephone lines
than a conventional modem can provide. It does this by
utilizing frequencies that are normally not used by a
voice telephone call, in particular, frequencies higher
than normal human hearing. This signal will not travel
very far over normal telephone cables, so ADSL can only
be used over short distances, typically less than 2km.¡@
FUNCTION: Plain old telephone Service (POTS) filter allows only voice signals to pass through to
the subscriber's phone answering/fax machine and other analog devices while DATA signals pass onto the computer. DSL filter, "PHONE" line (pin 3&4) is conditioned and ADSL line (pin 2/5 & 3/4) is remained clear for DSL compatible devices.
FEATURES: - Isolate telephone equipment impedance from ADSL and Home Phone Network (HPN) housing wiring.
- Attenuate ADSL and HPN signal to phone equipment to prevent conversion to voice band signals.
- Minimize voice band interference-transmission, signaling, and supervision.

MICROFILTER
A DSL microfilter is an analog low-pass filter installed
on telephones and other analog devices to prevent
interference between such devices and Digital Subscriber
Line (DSL) service operating on the same line. Without
the installation of DSL microfilters, high-frequency
signals from analog devices can result in reduced
performance and connection problems with DSL service,
and the high-frequency signals from the DSL service can
result in line noise and other issues for analog
devices.
