Abstract:
A redundancy system for a telecommunications system comprising:one or more resources; a controller coupled to the resources via a controller bus; another controller coupled to the resources via another controller bus; and wherein the one or more resources are each coupled to the controller bus and the other controller bus, such that a change in control between the controller and the other controller may be accomplished by transmitting control data to the one or more resources to transfer from the controller bus to the other controller bus; and wherein configuration data for the controller is also transmitted to the other controller such that the controller and the other controller can both obtain active control of the telecommunications system; and wherein the one or more resources further comprise: a plurality of active transport units that are operable to establish and maintain telecommunications channels; at least one spare transport unit; and wherein the spare transport unit is operable to receive configuration data from any of the transport units so as to assume the operations of any of the transport units in the event of failure of one of the transport units.
