Abstract: Methods for detecting and correcting data errors in an RF data link include identifying valid data frames and corrupted data frames by measuring a data corruption level for each transmitted data frame, comparing the measured data corruption level for each corrupted data frame to a data corruption threshold, reconstructing the corrupted data frames having a data corruption level below the data corruption threshold, reconstructing the data block using data from valid and reconstructed data frames, and/or verifying the data in the reconstructed data block.

Abstract: In one embodiment, a receiver on a credit-based flow-controlled interface is configured to free one or more data credits early when a data payload is received that incurs fewer unused data credits within a buffer memory that is allocated at a coarser granularity than the data credits. In another embodiment, header credits and data credits are dynamically adjusted based on actual packet data payload sizes.

Abstract: Certain exemplary embodiments comprise a method, which can comprise automatically generating a trouble ticket responsive to a determined failure of one or more elements of a management Permanent Virtual Circuit (PVC). The management PVC can be established between a signaling device and a device communicatively coupled to a backbone network.

Abstract: A data verification method and system is provided. The data verification method includes the steps of transmitting data from a sender to a receiver over a signaling channel, transmitting a first set of bits to the receiver over a voice channel, wherein the first set of bits is generated using the data in the sender, and verifying the data through comparison between the first set of bits and a second set of bits that is generated based on the data in the receiver. The first and the second sets of bits may be a group of bits that are selected from a hash value using a selection mask in the sender and the receiver respectively, wherein the section mask has the same length as the hash value and the hash value is calculated based on the data, and the selection mask may be pre-defined between the sender and the receiver.
