Abstract: Computer-implemented methods and systems are provided that receive, at an implantable medical device (IMD), a programming package comprising a collection of configuration change requests, transaction credentials, and a signature indicative of a source of the programming package. The transaction credentials include a first hash of the collection of configuration change requests. The IMD validates an external device as the source by decrypting the signature using a key that is uniquely associated with the external device. The IMD verifies the transaction credentials and the configuration change requests of the programming package, and generates a second hash of the collection of configuration change requests. Responsive to both (i) the second hash matching the first hash and (ii) the transaction credentials and the configuration change requests being verified, the IMD executes the collection of configuration change requests to update an operating configuration of the IMD.

Abstract: Call admission methods for admitting connections into ATM/IP networks having a plurality of communication channels are disclosed. An overbooking technique is utilized which distinguishes among the different service classes. Each service class is assigned an overbooking factor. The call admission is determined based on the overbooking factor assigned to the class and the effective bandwidth for that service class. In addition, methods are disclosed for performing appropriate bookkeeping, i.e., updating and maintaining information concerning the state of the system.

Abstract: A switch or other processing element of a communication system is configured to detect automatically the particular version of an asynchronous transfer mode (ATM) user-network interface (UNI) protocol or other signaling protocol utilized by a customer premises equipment (CPE) device or other device coupled to the switch. The switch analyzes at least one message received in a signaling channel from the coupled device in order to determine the particular version of the protocol, and stores an indicator of the particular version of the protocol for use in subsequent interaction with the coupled device. Call processing functions of the switch may be reconfigured based at least in part on the determination of the particular protocol version.
