Introduction The present document describes H.248 example message flows that are exchanged between a MGC
37、 and an AGW/RGW in order to deliver a Plain Old Telephone Service (POTS). ETSI ETSI TR 183 040 V1.1.1 (2007-02) 7 1 Scope The present document describes example message flows that are exchanged between the AGW/RGW and the MGC for support of POTS lines based on the ETSI H.248 profile 1 and the H.248.
38、34 stimulus analogue line “stimal“ package. Other alternative POTS message flows based on the ETSI H.248 profile 1 and for example the H.248.1 analogue line package (“al“) are also valid and examples will be described in future versions of this document.“ 2 References For the purposes of this Techni

45、OTE: The “Q interface“ (e.g. ITU-T Recommendation M.3010, clause 3.26) relates to the “q reference point“ (e.g. ITU-T Recommendation M.3010, clause 3.27) and corresponds here to the interface between the H.248 AMG/RMG as Network Element Function (NEF) and the Operations Systems Function (OSF).

46、esidential media GateWay 4 Message Flows The message flows contain annotation that depict the key functions that are performed by the AGW/RGW and the MGC. Although the message flows are not exhaustive they cover the most common scenarios and serve as a framework for constructing flows for other mark
47、ets and other exceptional conditions not provided herein. Hence the flows shown in this document are examples only. Many similar or equivalent flows including the alternative use of descriptors and parameters are equally valid, provided they conform to the ETSI H.248 profile 1. The following salient
48、 points should be noted when reading the message flows: Message Header is excluded from the H.248 flows. A end is used to refer to the AGW/RGW/MGC entities where the originating/outgoing call is initiated. B end is used to refer to the AGW/RGW/MGC entities where the terminating/incoming call is init
49、iated. DialPlanI is the dial plan that is loaded in the AGW/RGW via the MGC for performing initial digit string matches. It is not overwritten and remains present in the AGW/RGW for its life time. Primitives that are applicable to the 2 wire analogue interface are shown using a dashed arrow. The following should be noted with respect to SDP: The delimiter at the end of SDP lines is “. However this is not illustrated in the message flows for clarity. In the Local Descriptor returned from the AGW/RGW to MGC the s, t, and o lines will be present. Similarly
