Patent ID: 8711836

Claim:
An apparatus comprising: a synchronization information receiver to receive network synchronization information from a network communication link that enables communications with a communication network, the received network synchronization information for synchronizing communication equipment with the communication network; a quality monitor to monitor a quality measure of the received network synchronization information; and a synchronization information distributor to provide, based on the received network synchronization information, local synchronization information for synchronizing local communication equipment with the communication network, and to provide, based on the received network synchronization information, remote synchronization information for transmission to remote communication equipment via a Quality of Service (QoS) forwarding mechanism over a Digital Subscriber Line (DSL) communication link, the remote synchronization information for synchronizing the remote communication equipment with the communication network, the local communication equipment and the remote communication equipment comprising respective installations of wireless communication equipment that are coupled to a further communication network comprising the DSL communication link and provide a wireless communication service to wireless communication devices within respective service areas, the network communication link comprising a bonded communication link, the synchronization information receiver being operable to isolate respective redundant frequency reference signals from multiple DSL communication links of the bonded communication link, the redundant frequency reference signals comprising the network synchronization information, one of the redundant frequency reference signals being selected for use as basis for the local synchronization information responsive to a result of monitoring by the quality monitor, the quality measure comprising respective error rates of the redundant frequency reference signals, the redundant frequency reference signal having a lowest error rate being selected for use as basis for the local synchronization information, the synchronization information distributor being operable to determine the respective error rates based on a PRBS (Pseudo-Random Bit Sequence) that is combined with the redundant frequency reference signals.
