IPC: H04L12/56
Filed: 1995-04-27
Abstract: PURPOSE:To obtain a switching system in which queue control according to a dynamic scheduling algorithm is attained by adding a tag representing a destination bit and an output sequence to a cell. CONSTITUTION:A cell reaches an input processing section 16 via an input link 14. The input processing section 16 processes the arrived cell for each cell. The input processing section 16 calculates a tag for each cell in addition to the internal processing conducted by any ATM switch. The tag is calculated based on the scheduling algorithm corresponding to a virtual channel of the cell. After the calculation, the tap, destination information and a buffer address of the cell are outputted and stored in a queue of a queue retrieval section 18. Since a tag in a binary number is added to each cell stored in the queue, the queue retrieves a cell having a minimum value tag quickly among cells having a specific destination.

IPC: H03F3/00
Filed: 1987-04-27
Abstract: PURPOSE:To simplify the circuit constitution by providing an object emphasis characteristic to each of input circuits of an FM modulation circuit comprising an oscillation circuit whose oscillating frequency is varied depending on the current generated from a current source and the plural input circuits varying the current generated from the current source in response to the signal. CONSTITUTION:A signal VA is impressed to an input terminal 30A and zero or a negative voltage is impressed to an input terminal 30B to turn off a transistor (TR) 6. The signal VA is converted into a current by a TR 5 and in this case the signal is subjected to emphasis processing by resistors R3, R4 and a capacitor C2. Since the change in the collector current of the TR 5 is a change in the current flowing through TRs 3, 4, the oscillating frequency of the multivibrator is demodulated while being subjected to emphasis processing. Thus, the output signal V0 subjected to emphasis processing and FM modulation suitable for the recording system A is obtained. Conversely, in applying the signal processing suitable for the recording system B, the TR 5 is turned off and a signal VB is impressed on the input terminal 30B.

Abstract: PURPOSE:To suppress oscillation at an unnecessary wavelength created at the rise of pulse modulation and obtain excellent transmission characteristics by inserting a saturable absorber into a light path between a laser and an optical fiber. CONSTITUTION:A saturable absorber 5 is inserted into a light path between a laser 1 and an optical fiber 4. The light absorption mechanism consists of absorption between band and band or absorption between band and impurity. In this case, when a laser oscillates at a wavelength of, for instance, 1.55mum, the semiconductor material with a high energy corresponding to the band gap of 1.55mum or larger is employed. In order to realize the saturable absorption in the semiconductor. The semiconductor is doped with an impurity having a level suitable for creasing the absorption of a light with a wavelength of 1.55mum. If a laser beam is applied to a board made of semiconductor like this, the absorption is continued until photo density becomes equal to impurity density and the light is not absorbed after that and the saturable absorption is realized. With this constitution, excellent transmission characteristics can be obtained.
