A table of M3UA/SUA/SGMP instances. There can be multiple M3UA or SUA instances on a given Signaling Gateway. Each instance is uniquely identified by the port number. The local port number of the ASP (cItpXuaAspLocalPort) matches with the port number of the instance (cItpXuaInstPort). Also for a given instance, there can be multiple local IP addresses which are used for the multi-homing feature of the SCTP associations. There can only be one instance of SGMP. M3UA or SUA instances can be offloaded to a VIP on a 7500 platform. When an instance is offloaded, all ASPs that belong to that instance are also offloaded. Entries are added to this table via cItpXuaInstRowStatus in accordance with the RowStatus convention.
