6. Splitter/ Micro-filter Connection
The Splitter / Micro-filter are important for ADSL installation, they help direct
high-frequency signals to the ADSL modem & low frequency signals to the
telephone or other analogue device to prevent inter-modulation distortion & get
good speed/stable ADSL sync rate.
a) Splitter connection
If the installation has only a single telephone and a single ADSL modem, then a
splitter can be employed.
b) Micro-filter connection
If the installation has several telephones or other analog devices, then an internal
micro-filter can be employed at each analog device.
