Methods, systems, and computer readable media can be operable to facilitate the recovery of a failed data path. A determination may be made that one or more channels have become unavailable to a central device. The central device may identify an opportunity to attempt to recover the one or more unavailable channels, the opportunity being based upon a waiting period, time-of-day, device activity, or other parameter. A communication interface associated with the central device may be re-initialized so that the central device can attempt to recover the one or more unavailable channels.

Automatic recovery from impaired data path

Switch and MAC layer components are located at a headend and PHY layer components for connecting a plurality of end-user devices are located remotely at nodes. Using SSMII technology, MAC layer ports can communicate with an equal number of PHY layer interface ports serially. Thus, the MAC layer connects to the PHY layer via fiber links, a separate link being used for each direction of traffic data flow. Information data is encoded along with a frame sync signal and a clock signal into a serial stream for transmission across the network. The serial stream is decoded at the other end, and the frame sync signal is extracted to provided timing functionality. This allows full duplex operation with the MAC layer separated from the PHY layer at distances greater than a few inches. Also, user device status may be monitored at the single switch location.
