Q: What’s the maximum length of the telephone cable from the FXS interface of router to the phone set?
A: It is suggested that the length of the telephone cable be not more than 200 meters.
Note: The telephone cable connected to the FXS interface can adopt the indoor cabling mode only. The outdoor cabling mode may have a negative impact on voice, resulting from great interference. A more serious case is that the lightning strike may result in the damage of the whole router!
