AC power contact test
This test simulates the direct contact between the telecom lines and the AC mains lines.
The AC power contact test consists in applying 240 V
minutes to the device under test. The ITT K17 recommendation specifies an internal
generator impedance allowing 10 A
The behavior of the TSI with respect to this surge is given in

due to the action of the serial PTC that limits the current through the line. This PTC is
mandatory for this test. It can also be replaced by a fuse or any other serial protection that
“opens” the line loop under AC contact test.
