4.Splitter/ Micro-filter Connection
Splitter / Micro-filter are important for ADSL installation. High-frequency signals are directed to the ADSL modem, and low-frequency signals are directed to the telephone or other analog voice-channel device to prevent inter-modulation distortion and also to get good speed and 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.
