Abstract
In one embodiment, a method for providing voice and data service includes receiving voice telephone signals and data signals, and transmitting packets in a single protocol link layer over a subscriber line in response to the received telephone signals and the received data signals. The method also includes receiving packets in a single protocol link layer over the subscriber line, and transmitting data signals and voice telephone signals in response to the packets received from the subscriber line. In one embodiment, a network node and a network terminal unit communicate voice telephone signals and data signals by communicating packets in a single protocol link layer over a subscriber line. In another embodiment a first network node communicates voice telephone signals and data signals with a second network node by communicating packets in a single protocol link layer.
