Organization: ITU-T
Publication Date: 1 July 2019
Status: active
Page Count: 26
scope:

This Recommendation complements the physical layer (PHY) specification in [ITU-T G.9701].

It specifies:

− power spectral density (PSD) limit mask requirements;

− a set of tools to support reduction of the transmit PSD mask;

− profile control parameters that determine spectral content, including the allowable maximum aggregate transmit power into a specified termination impedance; and

− a methodology for transmit PSD verification.

This ensures that the technology can address:

− regional requirements;

− operator deployment requirements, for example, compatibility with other digital subscriber line (DSL) technologies;

− applicable electromagnetic compatibility (EMC) regulations or standards; and

− local EMC issues.

For in-band limit PSD mask LPM_106high, in the case where transmission is not limited to networks with increased shielding, such as those with shielded cables or where cables are buried underground, conformance of equipment with this Recommendation may not ensure compliance with specific national or regional regulation on electromagnetic compatibility when installations are brought into service.
