Among the three options described in the introduction, this Recommendation limits the scope to the employed technologies to improve spectral efficiency for downstream and upstream over hybrid fibre/coax (HFC)-based networks. The requirements stated herein are intended to be technology neutral. Furthermore, this Recommendation defines the requirements for advanced digital cable transmission technologies on the physical layer, which includes modulation, channel coding, transmission schemes and frame structure for providing higher spectral efficiency.

Recommendation ITU-T G.9902 contains the physical layer (PHY) and the data link layer (DLL) specifications for the ITU-T G.9902 narrowband orthogonal frequency division multiplexing (OFDM) power line communication transceivers operating over alternating current and direct current electric power lines over frequencies below 500 kHz. This Recommendation supports indoor and outdoor communications over low voltage-lines, medium-voltage lines, through transformer low-voltage to medium-voltage and through transformer medium-voltage to low- voltage power lines in both urban and long-distance rural communications. This Recommendation addresses grid to utility meter applications, advanced metering infrastructure (AMI) and other 'Smart Grid' applications such as the charging of electric vehicles, home automation and home area network (HAN) communications scenarios. This Recommendation does not contain the control parameters that determine spectral content, power spectral density (PSD) mask requirements and the set of tools to support a reduction of the transmit PSD; all of which are detailed in [ITU-T G.9901].

Recommendation ITU-T G.9904 contains the physical layer (PHY) and data link layer (DLL) specification for PRIME narrowband orthogonal frequency division multiplexing (OFDM) power line communication transceivers for communications via alternating current and direct current electric power lines over frequencies below 500 kHz. This Recommendation supports indoor and outdoor communications over low-voltage lines, medium-voltage lines, through transformer low- voltage to medium-voltage and through transformer medium-voltage to low-voltage power lines in both urban and in long distance rural communications. This Recommendation addresses grid to utility meter applications, advanced metering infrastructure (AMI), and other 'Smart Grid' applications such as the charging of electric vehicles, home automation and home area networking (HAN) communications scenarios. This Recommendation removes the control parameters that determine spectral content, power spectral density (PSD) mask requirements, and the set of tools to support reduction of the transmit PSD, all of which have been moved to Recommendation ITU-T G.9901.

This Recommendation deals with the risk management of lightning protection of telecommunication networks using cables with metallic conductors. The risk assessment is limited to physical damage and failure of insulation of telecommunication lines (buried or aerial cables, shielded or unshielded cables) which can cause the loss of service. This Recommendation provides a procedure for the evaluation of such a risk. Once an upper tolerable limit for the risk has been selected, this procedure allows the selection of appropriate protection measures to be adopted to reduce the risk to a level at or below the tolerable limit. This Recommendation shall be used together with [ITU-T K.47], which provides the risk assessment and the protection measures against lightning flashes to the telecommunication line and to connected structures, and [ITU-T K.46], which provides the risk assessment and the protection measures against lightning flashes near the telecommunication line. The protection need for line equipment (such as multiplexers, power amplifiers, optical network units) and line termination equipment is not considered in this Recommendation and it should be evaluated using the risk assessment applied to the structure where the equipment is located (i.e., exchange, customer's building, or remote electronic site). The protection of persons using telecommunication equipment inside the customer's structure, from dangerous situations caused by touch voltages is outside the scope of this Recommendation and it should be evaluated using the risk assessment applied to the customer's structure.
