<p>In an integrated digital network with at least three nodes, A (31), B (33), and C (35), a call placed at node A (31) to be transmitted through the network from node A (31) to node B (33) to node C (35), is compressed in multiple modes. In response to the path selected, the speech signal in node A (31) is compressed in a first mode for transmission to node B (33). In node B (33), the speech signal is compressed in a second mode for transmission to node C (35), where the first and second modes involve dissimilar algorithms for compression of speech signals. At node C (35), the speech signal would again be adapted for supply to a receiving station. The system can accommodate as many modes of compression as desired.</p> |
