4.2.2. DC characteristic :

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

from 0mA to 100mA. This ISDN splitter can pass ISDN tip-to-ring dc voltages of 0V to 72V

and ringing signals of 40V to 80Vrms at any frequency from 22Hz 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 12.5 ohms. The

DC resistance from tip-to-ground and from ring-to-ground at the ISDN 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.
