scope:

The present document defines the transmitted signal characteristcis delivered across a HFC cable network to the customer network interfaces distributed within the home network received and processed by the consumer end terminals for reception of multimedia services.

The signal characteristics are defined across the operating frequency and in accordance with network equipment built to European standards.

The present document provides valuable input to engineers and developers containing the technical basis to take into account when developing harmonized technical conditions for new radio services operating in the same frequency range as currently occupied by cable distribution networks.

It presents the technical basis for coexistence between these new radio services and existing non-radio end-user equipment for fixed broadcasting and broadband electronic communication services, specifically those services delivered by European cable based systems (PAL/SECAM, DVB-C, Euro-DOCSIS).

The impact to non-radio end user equipment for fixed broadcast and broadband electronic communication services is given in terms of the operational characteristics of the wanted signals and tolerable limits of the unwanted signals as a factor of the distance between them before the unwanted interfering signal will disrupt the end users equipment for fixed broadcasting and broadband electronic communication services (e.g. digital and analogue television, internet high speed data and telephony services).
