the resistance from ring to tip is measured if this resistance is again greater than 50k u03c9 the wires pass and the next test is performed this test also known as a 34 continuity test 34 determines if the ringer in the customer 39 s telephone is connected by measuring the capacitance of the customer 39 s ringer if the ringer is connected the wires pass all tests if not the wire fail and an indication of 34 no ringer 34 is given going back to step 3 if the resistance is not greater than 50k u03c9 the wires must be tested further to determine if there is in fact a leak or if the customer 39 s receiver is off hook these tests are illustrated in the right hand leg of the diagram thus in the next test with the tip conductor again grounded resistance is measured with a 15 milliamp current applied if the measured resistance is not less than 650 u03c9 the wires fail the leak test since the receiver could not exhibit this resitance if the receiver were off hook if the resistance is less than 650 u03c9 the resistance of ring to tip is again measured since there still might be an off hook condition but this time with 1 milliamp of current through the wires if the resistance is not greater than 200 u03c9 the wires fail the leak test since again there cannot be an off hook condition exhibiting this resistance if the resistance is greater than 200 u03c9 the wires are tested one more time to determine.
