`
`ABSTRACT
`
`The present invention describes a system and method for
`communicating voice and data over a packet-switched net-
`work that is adapted to coexist and communicate with a
`legacy PSTN. The system permits packet switching of voice
`calls and data calls through a data network from and to any
`of a LEC, a customer facility or a direct IP connection on the
`data network. The system includes soft switch sites, gateway
`sites, a data network, a provisioning component, a network
`event component and a network management component.
`The system interfaces with customer facilities (e.g., a PBX),
`carrier facilities (e.g., a LEC) and legacy signaling networks
`(e.g., SS7) to handle calls between any combination of
`on-network and off-network callers.
`
`The soft switch sites provide the core call processing for the
`voice network architecture. The soft switch sites manage the
`gateway sites in a preferred embodiment, using a protocol
`such as the Internet Protocol Device Control (IPDC) proto-
`col to request the set-up and tear-down of calls. The gateway
`sites originate and terminate calls between calling parties
`and called parties through the data network. The gateway
`sites include network access devices to provide access to
`network resources. The data network connects one or more
`of the soft switch sites to one or more of the gateway sites.
`The provisioning and network event component collects call
`events recorded at the soft switch sites. The network man-
`agement component includes a network operations center
`(NOC) for centralized network management.
