4.4 DC characteristic
All requirements of this specification can be met in the presence of all POTS loop currents
from 0mA to 80mA. This filter can pass POTS tip-to-ring DC voltages of 45 to 52V and
ringing signals of 100Vrms at frequency range from15.3Hz to 68Hz with a DC component in
the range from 45 to 52V. The DC resistance from tip-to-ring at the line port interface with
the phone interface shorted, shall be less than or equal to 50Ω for one splitter. The DC
resistance from tip-to-ground and from ring-to-ground at the POTS interface with the U-C
interface open shall be greater than or equal to 5MΩ. The ground point shall be local
building or green wire ground. As an objective, the DC resistance should exceed 20MΩ.
