Abstract: A method and system for controlling configuration of a relay, where the relay has a coverage footprint and provides service on a first air interface having a frequency bandwidth, and where the relay is served by a donor access node over a second air interface on which the donor access node provides service. Per the disclosure, an entity detects that load on the second air interface on which the donor access node provides service is threshold high, and in response to at least that detecting, the relay is made to reduce the coverage footprint of the relay and/or to reduce the frequency bandwidth of the first air interface on which the relay provides service.

Abstract: Systems and methods for fault tolerant communication are provided. A base site is coupled to a central office via a channel service unit. The channel service unit is coupled to the central office via primary and secondary communications links. A first and second permanent virtual circuit couple the channel service unit to a wireless carrier core network. When there is a fault on the primary communication link or the primary permanent virtual circuit user network interface of an aggregator, the secondary communication link is established and the secondary permanent virtual circuit is activated. Communications are then routed to the wireless carrier core network via the secondary communication link and the secondary permanent virtual circuit.
