Abstract:
1. A method of extending a data service of a legacy network through a broadband packet network, the method comprising steps of: a) at an ingress gateway, accumulating payload data comprising a predetermined number of successive bytes of a data stream respecting the data service independently of a communications protocol of the data stream, the data stream being a legacy data stream originating in the legacy network and received by the ingress gateway through the legacy network; b) encapsulating the payload data within a container; c) encapsulating the container within a protocol data unit (PDU) of the broadband packet network; and d) forwarding the PDU through the broadband packet network to an egress gateway irrespective of routing information contained within the data stream; wherein the data stream is a circuit-switched data stream comprising pulse code modulated PCM signals, and the number of accumulated bytes forming the payload data is equivalent to Ps=(Nc×Nm)×n, where:
