Abstract
An ingress TDM network segment () and an egress TDM network segment () are connected by a packet-switched network (). An ingress inter-working function () receives a TDM traffic flow () and an ingress data clock (). A first mapping function () maps the TDM data () into first data containers using an ingress reference clock (). The first mapping function conveys a difference between the ingress data clock () and the ingress reference clock () by a rate of justification operations to the mapped data within the first data containers. A second mapping function () maps the first data containers into second data containers using an ingress line clock (). The mapping conveys a difference between the ingress reference clock () and the ingress line clock () by a rate of justification operations to the mapped data within the second data containers. Re-mapping is performed at boundaries between packet sub-networks ().
