Abstract

Embodiments disclosed herein provide a hybrid fiber-copper access network in which a main OLT sends data to the DSLAMs via a plurality of point-to-point optical fiber connections. A standby OLT is provided which has a plurality of point-to-multi-point optical fiber connections to the DSLAMs. In the event of a failure, data can be sent to some of the DSLAMs via the standby OLT and the point-to-multi-point optical fiber connections. Following the rectification of the fault, the network can revert to its normal state and transmit data to the DSLAMs via the main OLT and the plurality of point-to-point optical fiber connections.
