4.2.4. DC characteristic :

All requirement of this specification can be met in the presence of all POTS loop currents

from 0mA to 100mA. This POTS splitter can pass POTS tip-to-ring dc voltages of 0V to

72V and ringing signals of 40V to 80Vrms at any frequency from22Hz to 28Hz with a DC

component in the range from 0V to 72V. The dc resistance from tip-to-ring at the line port

interface with the phone interface shorted, shall be less than or equal to 25 ohms. The DC

resistance from tip-to-ground and from ring-to-ground at the POTS interface with the U-R

interface open shall be greater than or equal to 5 Megohms. The ground point shall be

local building or green wire ground. As an objective , the dc resistance should exceed

10MΩ.
