Impulse voltage generator for telecom applications EMC Partner AG
ITU T-K44, K20, K21 FCC part68

The ITU T-K44 recommendation describes a series of surge impulses for telecom applications. Besides the ITU requirements, similar impulses are specified in the FCC part 68 standard for telecom terminal equipment.
ITU tests are divided into Basic and Enhanced levels. Basic level tests are disturbance tests where the Equipment Under Test(EUT) should recover from the impulse disturbance. Enhanced level tests cause destruction of the EUT. The purpose of these tests is to ensure the equipment does not become a fire or fragmentation hazard. 10/700us impulses are applied to telecom lines at up to 6kV for enhanced level. 8/20us current impulses test protection devices mounted in telecom interfaces and the Combination Wave Generator(CWG) is used on power interfaces.
EMC PARTNER offer a range of test equipment to meet these requirements.
