GR 3053 CORE : ISSUE 1

Defines generic requirements applicable to Signaling Gateways (SGWs) in Voice over Packet (VOP) Next Generation Networks (NGNs). The SGW provides signaling connectivity between a Signaling System Number 7 (SS7) signaling network and a VOP network. This document defines the functional requirements for the SS7 interface, packet network interface, management interworking between the SS7 and packet network, and interaction between the SGW and the Call Connection Agent (CCA) in the VOP network. It also specifies an overview of the VOP network management strategy and details functional operations requirements that need to be supported by an SGW. This GR is one of a set of GRs for the operation of VOP in NGNs.
