Abstract:
1. An automated telecommunications backup system operable to provide an alternative transmission route for time division multiplexing (TDM) telecommunications traffic being transmitted over a primary TDM link, comprising: a first system operable to monitor the primary TDM link between a first telecommunications node at a first location and at least one second telecommunications node at an at least one second location on a TDM network for a failure condition, wherein at least one of the first location and the at least one second location comprises at least one of a customer premises, or a network provider premises; and a second system operable to interface to back up at least a portion of the TDM telecommunications traffic of the TDM link over an Internet protocol (IP) packet based backup network, wherein said first system that monitors the primary TDM link, upon the detection of the failure condition, causes said second system to switch into circuit the IP packet based backup network, wherein said second system is further operable to interface the TDM telecommunications traffic to be transported between the first telecommunications node and the at least one second telecommunications node on the TDM network wherein said second system is operable to at least one of: wherein the TDM clock of TDM equipment at the at least one second location is kept in delayed operational synchronization with the TDM clock of TDM equipment at the first location by adjusting the TDM clock at the at least one second location to meet delay and jitter requirements of the TDM equipment coupled together by the IP packet based backup network, and wherein said second system is operable to reestablish the primary TDM link upon detecting by said first system that the primary TDM link has been restored.
