scope:

The stimulus analogue line package defines ITU-T H.248 signals and events that are exchanged between a media gateway (MG) and a media gateway controller (MGC) for controlling analogue plain old telephone service (POTS) lines which can, for example, be used to host telephones, analogue private branch exchanges (PBXs) and turn-key systems. The signals and events defined in the package are stimulus in nature and enable the full set of POTS services that are delivered via a V5 local exchange (LE) and access network (AN) to be ubiquitously provided in a next generation network (NGN) MG and MGC architecture.

NOTE - The use of the Call Finished signal is a national option. It is included as part of a joint text with ETSI. In normal circumstances, the national specific functionality shall be included as a separate package. The use of the Call Finished signal shall not compromise existing ITU-T H.248 procedures.
