摘要： In a high-speed packet multiplex communication network including a transmission line with a predetermined bandwidth and accommodating a plurality of information sources, the sources having various packet delivery rates over a range of between a peak rate and a lower rate than an average rate and demanding various transport performances, the sources are preliminarily classified into a plurality of types according to transport performances required and different transmission priorities are assigned to the different types, respectively. Bandwidths of sources of first priority and second priority are determined ones corresponding to the peak rate and the average rate, respectively. A virtual bandwidth may be calculated for the second priority source as a value between the peak and average rates. In response to connection requests from the sources, each of the connection requests is admitted when a bandwidth defined by the priority of each source is accepted in a residual bandwidth of the predetermined bandwidth, and the packets from the source of the first priority are preferentially transmitted to the transmission line, packets of the second priority source are transmitted when packets of the first priority source are absent. Thus, high bandwidth efficiency is insured while the high transport performance of the first priority source is maintained.

摘要： Signals on an incoming highway of a time division switching system are written into an alternate one of first and second time switch memories and are sequentially read out of the other alternate one of the memories into the time slots of an outgoing highway of the system in accordance with a phase difference between incoming and outgoing frames and a time slot interchanging relationship between signals on the incoming highway and corresponding signals on the outgoing highway, so that the beginning of the outgoing frame coincides with one of the time slots of the incoming frame which is displaced from the beginning of the incoming frame by an amount equal to the detected phase difference. Alternatively, if the time slot of at least one signal of a multi-channel call on the incoming highway is later than the time slot of a corresponding signal on the outgoing highway, all signals of that multi-channel call are sequentially read out of the memories into a given outgoing highway so that they correspond to those on an incoming frame which is one frame prior to the one being written at the beginning of the given outgoing frame. If the time slots of all signals of a multi-channel call on the incoming highway are earlier than those of respectively corresponding signals on the outgoing highway, all signals of that multi-channel call are sequentially read out of the memories into an outgoing frame so that they correspond to those on an incoming frame which is being written at the beginning of the outgoing frame.

摘要： A system and method for operating a Broadband ISDN to support a viable virtual private network (VPN) service are attained by establishing a plurality of virtual path links connecting customer locations and broadband switching systems, by cross-connecting virtual channel links at the broadband switching systems to establish end-to-end virtual channel connections, and by policing both the input and output traffic only on the virtual path links. The egress policing function is attained through the use of the ingress policing processors by looping back one customer's traffic from an outgoing trunk into an input port on the broadband switching system.

摘要： A negative-phase output signal in an ECL circuit is extracted by an emitter-follower circuit, and the extracted signal is differentiated at its leading edge by a capacitor driven by the emitter-follower circuit so as to form a pulse wave, thus the differentiated signal drives a transistor connected in parallel with an emitter-follower resistor to which a positive-phase output signal is supplied. With this operation, a large amount of current flows only at the trailing edge of the output signal to shorten the fall time of the output from the logic circuit.

摘要： In a time division switching system, a reference pulse generator generates constant reference timing pulses for operating a switch. First and second variable phase pulse generators generate first and second trains of variable phase timing pulses. Data signals on a first group of input lines are multiplexed in response to the timing pulses of the first train to produce a first time division multiplexed (TDM) signal and data signals on a second group of the input lines are multiplexed in response to the timing pulses of the second train to produce a second TDM signal. The TDM signals are carried on first and second highways respectively to the space switch. The first and second variable phase pulse generators are controlled so that the timing of each of the first and second TDM signals coincides in the space switch with the reference timing pulse.
