How to limit the noise in the telephone?
All modems ADSL are not identical vis-a-vis the noise. Some do not allow any more the use of the old telephone so much there is noise on the line. How much time did I hear "you can speak more extremely, I do not hear you"?
But It is true also that certain operators estimate that the traditional telephone line is obsolete, thanks to their subscription unlimited on their line téléphonique(IP). See impossible if one passes in total deblocking. In this case, only the telephone
connected on the modem functions.
For those and those which want to still use to them ' vieux' telephone, time that the friends compare that their telephone number to changed,
IT SHOULD BE KNOWN THAT IT IS COMPLETELY POSSIBLE TO PUT SEVERAL FILTERS ADSL IN SERIES.
As long as you find that the level of noise is too high, add a new filter. On the other hand, each filter lowers the noise level of 2dB in the telephone, therefore the maximum number will depend on your telephone. But up to 3, there should
not be problem.
Always connect the telephone at the end and modem ADSL ALWAYS on the first filter.
