This Recommendation describes a Stimulus Analogue Line package that defines new H.248 events, signals and parameters derived from the V5 PSTN protocol defined in ITU-T Rec. G.964.

To assist both vendors and operators in migrating V5 Local Exchange and access network nodes to a Next Generation Network Media Gateway and Media Gateway Controller architecture, the package provides guidelines for mapping the V5 PSTN Protocol to the "Stimulus Analogue line" package, other H.248 packages and the H.248.1 protocol.
