  • Patent number: 8000429
    Abstract: In a jitter correction method and circuit, combination data combined by adding, to referenced data, an end bit of data 1 clock prior to and a head bit of data 1 clock subsequent to the referenced data is sequentially generated. Each bit of the combination data is sequentially referred. When a change between a referenced bit and a bit directly adjoining the referenced bit is detected, and when a number of references reaches a multiplication number of the oversampling and a change between at least three adjoining bits including the referenced bit is not detected, change position display data regarding the directly adjoining bit as a change bit of the referenced data is generated and the number of references is initialized. When the change is not detected and the number of references does not reach the multiplication number, the number of references is incremented.

  • Patent number: 7418036
    Abstract: In a method and a circuit for timing pulse generation, a frame pulse of a corresponding system is masked when an alarm signal of either a working system or a protection system is received, a monitoring window which indicates an absorbable range of delay time difference between the frame pulses is generated upon an arrival of the frame pulse of the system selected by a switching signal, when the alarm signal of a system not selected is generated upon selection of the switching signal. Alternatively, a request signal for regenerating the monitoring window which indicates an absorbable range of delay time difference between the frame pulses is provided upon an arrival of the frame pulse of the system selected by the switching signal, when a slip signal is generated upon selection of the switching signal.

  • Patent number: 7400655
    Abstract: A transmission device which cross connects channels on a synchronous multiplex transmission network which forms a ring, and which performs restoration of communication by looping back signals in a protection path when a failure occurs includes a memory area which stores information for determining whether an alarm indication signal needs to be inserted in a channel or not, wherein the size of the memory area corresponds to the number of channels targeted for the restoration, and a part which inserts said alarm indication signal in a channel by switching results of the determination according to predetermined information. Further, the transmission device may switch and recover a path without skipping an event which arises between polling accesses by a CPU of said transmission device. Furthermore, the transmission device may include a part, provided in each interface part, which performs phase adjusting of channel signals.

  • Patent number: 7397882
    Abstract: A digital phase locked circuit provides an output clock signal whose phase is synchronous with the phase of an input clock signal under a desired level of a phase absorption characteristic even if the input clock signal is supplied in a burst fashion. A phase comparing part compares the phase of the output clock signal with the phase of the input clock signal. A phase comparison result detecting part outputs an INC/DEC request signal for controlling a division operation based on a phase comparison signal. An execution rate computing part computes a phase difference between the input clock signal and the output clock signal based on the INC/DEC request signal and outputs an execution rate corresponding to the phase difference. A clock generating part controls a division operation for the master clock signal in accordance with the INC/DEC request signal and changes phase absorption speed of the output clock signal in accordance with the execution rate.

  • Patent number: 7355967
    Abstract: There is disclosed a transmission device performing NUT setting and its establishment efficiently and precisely. A setting information relay unit relays setting information that places a specific channel out of a channel used for restoration. A channel establishment unit determines, by referring to the setting information, whether a channel of interest should be placed out of a channel for restoration and establish the channel. A route switch control unit recognizes a section in which the channel that is not used for restoration has been established and a fault bypass control condition at the time of occurrence of a fault and performs a route switching control based on a result of recognition.
