The method for determining jitter of a signal in a serial link according to the invention comprising the following steps: First, a section of the signal transmitted via a transmission channel is sampled at different sampling times. The total number of edges in the section is determined. The neighboring sample values are analyzed and from that a statistical value is formed. From the statistical value and the total number of edges a figure of merit is determined. Finally, by means of a look-up table or a jitter-versus-figure of merit curve, the total jitter corresponding to the figure of merit is derived.

A VTMS queue scheduler integrates traffic shaping and link sharing functions within a single mechanism and that scales to an arbitrary number of queues of an intermediate station in a computer network. The scheduler assigns committed information bit rate and excess information bit rate values per queue, along with a shaped maximum bit rate per media link of the station. The integration of shaping and sharing functions decreases latency-induced inaccuracies by eliminating a queue and feedback mechanism between the sharing and shaping functions of conventional systems.

A method and apparatus for preauthorizing electronic fund transfers from a consumer's bank account without obtaining actual written authentication from the consumer is implemented in connection with a direct marketing strategy for a financial product which, in the presently preferred embodiment of the invention, is a mortgage acceleration program. The invention provides for the mailing of a solicitation to a consumer, i.e. a prospective customer, based upon such factors as mortgage data that the financial institution may posses concerning the consumer. The mailing includes an authorization and passcode which, in the presently preferred embodiment of the invention, is an ACH authorization and passcode. When the consumer receives the solicitation, he may decide to enroll in the mortgage acceleration program. The consumer places a telephone call to a telemarketing organization at a telephone number that accompanied the solicitation. The consumer provides the passcode to a representative of the telemarketing organization and the telemarketing organization attempts to verify the passcode. If the passcode is successfully verified, then the consumer is enrolled in the mortgage acceleration program. Thus, the invention provides a deceptively simple and specific implementation of the “similarly authenticated” requirement of the EFTA that is applicable to direct marketing solicitations made by, or on behalf of, financial institutions. That is, the passcode provided by the consumer meets the requirement of a “digital signature or other code.” Yet, the consumer is not required to provide an actual written signature, nor is the consumer required to use a computer or other electronic means to conclude the transaction.

A communications system employs a HARQ method and, for at least some transmission formats, incremental redundancy (IR) signals. For such formats, the multiple IR signals are derived from a single turbo encoded signal by forming multiple permutations of the encoded signal.

The method relates to discriminating between an internal arc and a circuit-breaking arc established in the enclosure of a circuit breaker in a bay of a medium or high voltage metal-clad substation. The appearance of an internal arc is detected by a protection system which responds by transmitting a disengagement order to the circuit breaker, thereby causing a circuit-breaking arc to appear. The pressure of the dielectric gas inside the enclosure of the circuit breaker, is continuously measured and recorded so that after the instant at which the disengagement order is transmitted, it is possible to recover a first pressure value measured before the instant. The first pressure value is then compared with a second pressure value measured after the said instant in order to identify whether the internal arc was struck in the circuit breaker enclosure.
