This Recommendation defines several packages that provide support for extended line supervision and metering analogue lines capabilities for ITU-T Rec. H.248. This version adds a phased metering signal suitable for use with complex metering scenarios that are beyond the capability of the metering signals already present in the package. It also introduces a new package to perform metering pulse detection by Media Gateways, and updates all the packages in this Recommendation to conform to the new Packages Template.
