摘要： A method, a system, and a network entity enable a detection of a connection fault and perform the switch-over in less than 50 ms. CV packets are being sent, for example, 1/10 ms (1 CV packet per 10 ms) or 1/15 ms (1 CV packet per 15 ms). The interval of the CV packets, consequently the frequency for sending CV packet, can be any interval that makes the switch-over time for a protected substantially real-time connection achievable. Moreover, the interval (the frequency) should be such that the interval makes the fault detection from the fault event to occur in less than 50 ms and triggers the switch-over to occur also in less than 50 ms from the occurrence of the fault event.

摘要： 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.
