Abstract :
The new editions of CISPR 22/EN 55022 as well as CISPR 24/EN 55024 require testing of emission and immunity on telecommunication ports of information technology equipment (ITE) and telecommunication equipment. Signal transmission on unshielded telecommunication lines need transmission bandwidths up to 100 MHz for systems like “ISDN”, “ATM” (asynchronous transfer modus), “ADSL”, “VDSL”, “FDDI” (fibre distributed data interface-with wired extensions), “token ring”, “10BaseT” and “100BaseT”. The paper discusses test procedures and requirements for ISNs
