Splitters and Microfilters
This appendix tells you how to install a POTS splitter or a telephone microfilter.
Connecting a POTS Splitter
When you use the Full Rate (G.dmt) ADSL standard, you can use a POTS (Plain Old Telephone Service) splitter
to separate the telephone and ADSL signals. This allows simultaneous Internet access and telephone service on
the same line. A splitter also eliminates the destructive interference conditions caused by telephone sets.
Install the POTS splitter at the point where the telephone line enters your residence, as shown in the following
figure.
Figure 161
Connecting a POTS Splitter
1
Connect the side labeled “Phone” or “TEL” to your telephone.
2
Connect the side labeled “Modem” or “DSL” to your ZyXEL Device.
3
Connect the side labeled “Line” to the telephone wall jack.
Telephone Microfilters
Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL transmissions
take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter, for your
telephone, to ensure that ADSL transmissions do not interfere with your telephone voice transmissions. The use
of a telephone microfilter is optional.
1
Locate and disconnect each telephone.
2
Connect a cable from the wall jack to the “wall side” of the microfilter.
3
Connect the “phone side” of the microfilter to your telephone as shown in the following figure.
