ABSTRACT:
A communications network is made up of a number of nodes. Frames of data transported on a circuit line are received at a first node of the network and segmented into packets such that a first packet includes a first portion of data from a frame and a second packet includes a second portion of data from the frame. A frame count value is added to a header in each of the first packet and the second packet. In addition, a first offset value is added to the first header and a second offset value is added to the second header. The first and second offset values correspond to respective temporal locations of the first and second portions of data from the frame of data. The first and second packet are transmitted across the telecommunications network to a second node where they are received and played out according to the frame count value and the first and second offset values such that the first and second portions of data occupy similar respective temporal locations within a played out frame as the first and second portions occupied in the original frame.
