Abstract: An active/standby switching system includes two AAL2 (ATM Adaptation Layer Type 2) cell assembling/disassembling processor units (20, 30) as an active system and a standby system so that active/standby switching is carried out between the active system and the standby system. The active/standby switching is carried out by transferring, from one of the AAL2 cell assembling/disassembling processor units (20) which has been the active system to the other AAL2 cell assembling/disassembling processor unit(30) which has been the standby system, handover information to prevent cell loss of AAL2 cells from occurring as a result of the active/standby switching and uncompleted cell data in the course of disassembling, the AAL2 cell assembling/disassembling processor unit (30) to become a new active system receiving the handover information and the uncompleted cell data and carrying out AAL2 cell assembling or disassembling.

Abstract: In a voice interception system, a voice is intercepted by applying a function of a vocoder installed in a voice signal processor to a mobile switching station. This interception implies a conversion between an ATM cell of an AAL2pf, an AAL2, and an AAL1 (PCM), and a conversion between an ATM cell of an AAL2pf and an AAL1 (TFO) in a TFO case. The ATM cell of the AAL2 in the ATM network is picked up from an ATM switch and is intercepted. If a voice TFO CODEC method is used, the above functions are applied to a voice monitor and a voice signal, during a telephone call between mobile stations, is intercepted. It is possible with the disclosed invention to carry out a voice interception only by controlling the ATM switch without individual control of both the ATM switch and an STM switch.

Abstract: In a voice interception system, a voice is intercepted by applying a function of a vocoder (9-1) installed in a voice signal processor (3-1) to a mobile switching station (2). The above-mentioned function implies the functions of a conversion between an ATM cell of an AAL2pf, an AAL2 and an AAL1 (PCM) and a conversion between an ATM cell of an AAL2pf and an AAL1 (TFO) in a TFO case. The ATM cell of the AAL2 in the ATM network is picked up from an ATM switch (2-2) and it is intercepted. In particular, if a voice CODEC method referred to as TFO is used, the above-mentioned functions are applied to a voice monitor (2-5). Accordingly, a voice during a telephone call between mobile stations is intercepted. A path connection around the voice monitor (2-5) in an exchange is carried out at an initially setting stage of the exchange.

A constant-current circuit is, in parallel, connected to a voltage dividing point of charge voltage of an output capacitor to be connected to an input terminal of an error amplifier of a booster converter circuit and realized by a plurality of resistors so that control of a constant-current value of the constant-current circuit is performed with the rectified output from the rectifying circuit. As a result, the loads to be borne by the circuit components of the AC-DC converter can be made constant regardless of the supplied AC voltage level so that the size and cost of the AC-DC converter are reduced.

Abstract: The present invention provides an AC-DC converter in which an application range of an AC input voltage can be extended, keeping a voltage in a circuit from rising at a light load. In an AC-DC converter having a rectifier 3, a boost chopper 4 and a DC-DC converter 5, a PWM circuit 6, an one-shot multivibrator 7, a pulse synthesizer 8 and a comparator 9 are further arranged. The pulse synthesizer 8 generates a second pulse signal having a pulse width being narrower by a pulse width of the delay pulse V.sub.pD than that of the first pulse signal V.sub.pa by means of the first pulse signal V.sub.pa which the PWM circuit 6 output s and a delay pulse V.sub.pD generating in said one-shot multivibrator 7. The comparator 9 compares a voltage V.sub.C boosted up by the boost chopper 4 with a reference voltage V.sub.REF to stop generating the delay pulse when voltage V.sub.C drops below the reference voltage V.sub.REF .

Abstract: This invention provides an AC-DC converter in which the shape and the cost do not increase by a measure for a harmonic distortion in the power factor improved AC-DC converter generating little harmonic distortion. In the AC-DC converter, a control input terminal of a switching transistor of an active filter is connected to an output terminal of a flip-flop, a set input terminal of which is connected to a DC-DC converter to receive a synchronizing pulse signal therefrom. A reset input terminal of the flip-flop is connected to an output terminal of a comparator to receive an OFF-timing signal from the comparator. The comparator determines OFF-timing of the switching transistor by comparing a level voltage with an outout voltage from a saw-tooth wave generating circuit. Thereby since it is not required that an active filter has a multiplier and an an oscillating circuit, its circuit construction is simple and the AC-DC converter in small size and at low cost is realized.
