A method is provided for protection switching in an optical network. The method may include establishing a baseline power level for a channel. The method may further include receiving a signal associated with the channel via each of a first path of the optical network and a second path of the optical network. The method may also include monitoring a power intensity of the signal received via the first path. The method may additionally include protection switching from the signal received via the first path to the signal received via the second path in response to a determination that the baseline power level exceeds the power intensity of the signal received via the first path by a predetermined threshold.

Method and system for protection switching

A method is provided for protection switching in an optical network. The method may include: (i) establishing a baseline power level for a channel and a threshold value for the channel approximately equal to a predetermined threshold value; (ii) receiving a signal associated with the channel via each of a first path of the optical network and a second path of the optical network; (iii) monitoring a power intensity of the signal received via the first path; (iv) determining an average power intensity of the signal received via the first path based on the monitored power intensity; (v) modifying at least one of the baseline power level and the threshold value in response to a determination that the average power intensity exceeds the baseline power level; and (vi) protection switching from the signal received via the first path to the signal received via the second path in response to a determination that the baseline power level exceeds the power intensity of the signal received via the first path by the threshold.

A system () for communicating information associated with one or more subscribers includes a connecting link (). A first switching system () coupled to the connecting link () communicates remote voice signals () and remote data signals () using the connecting link (). A second switching system () coupled to the connecting link () includes an interface () to receive the remote voice signals () and the remote data signals () using the connecting link (). The second switching system () also includes subscriber line ports () for receiving local voice signals () and local data signals () from subscribers. The interface () of the second switching system () selectively communicates the highest priority available signals using an outgoing link, voice signals () having higher priority than data signals (). In a more particular embodiment, the remote voice signals () may have higher priority than the local voice signals ().

System and method for prioritizing and communicating subscriber voice and data information

A system for switching and routing data associated with one or more subscribers within a subscriber community includes layer-2 switching functionality and an intermediate device, both within a first network access switch. The intermediate device is operable to receive data units from the layer-2 switching functionality and to selectively store first data units received by the intermediate device after layer-3 routing functionality has begun to process a data block comprising the first data units and before all other data units within the data block ahead of the first data units have been switched for communication and external device of layer 2 switching functionality of another network access switch.
