ITU-T K.93 PDF

This Recommendation provides an immunity test for home network devices against broadband disturbances. The purpose of this Recommendation is to ensure normal operation of telecommunication devices in home networks and to provide additional requirements that do not cover existing international standards. However, this Recommendation is not intended to replace or duplicate international or national regulations or laws.

With the advent of Internet technologies, there are many telecommunication devices being used on customer premises. Therefore, new electromagnetic compatibility (EMC) problems can occur in such environments. These problems are caused by broadband disturbances produced by electrical devices.

Many broadband services, such as Internet protocol television (IPTV) and voice over Internet protocol (VoIP), have been introduced to the home by telecommunication operators. These services require operators to be able to underwrite quality of service (QoS) levels, since both services are essentially streamed, and hence loss or delay of packets can be immediately apparent to the user as service interruptions. Resolving EMC issues of broadband services is one of the key factors for ensuring QoS in home networks. Furthermore, the width of the frequency band used in the home is increasing and shifting to a higher frequency range.
