Abstract
System and method for providing a termination point for service emulation instances in an access network is provided. In an embodiment, the service emulation instances are implemented utilizing, for example, pseudowires. Communications to and from the access network are aggregated and transmitted via one or more pseudowires to a service emulation instance terminator. The service emulation instance terminator converts the traffic to its native form and, if necessary, converts the traffic to a different type of format or service. The service emulation instance terminator then frames the traffic for the appropriate type of service and transmits the traffic to the service edge. Traffic received from the service is removed prepended with a pseudowire label and aggregated with other traffic. The aggregated traffic is transmitted to the customer via the access network. If necessary, an interworking function may convert the traffic from one type of service to another type of service.
