Title: Switching circuit
Inventor: YOSHIDA YUKIYOSHI
IPC: H03K17/62
Filed: 1982-02-06
Abstract: PURPOSE:To reduce the number of amplifiers, by grouping input signals for every plural numbers, amplifying the signals after time division with a contact switch in each group and time-dividing the signals with a contactless switch. CONSTITUTION:Analog signals are applied to input terminals T11-Tmn. Contact switches S11, S21...Sm1 are turned on simultaneously and each input signal is amplified with amplifiers AG1-AGm. The contactless switch S1 is set on near the end of the on-time of the switch S11 and with the turning off of the switch S1, the contact switch S12 and the contactless switch S2 are closed. Thus, the contactless switches S1-Sm are sequentially set on and off, then the contact switches having the present switching order in the switching group relating to the contactless switches are set on. Thus, the input signals at the terminals T11-Tm1 sequentially appears at an output terminal Tout, this process is repeated and the input signals at the input terminals T1n- Tmn appear at the output terminals.

IPC: H04L69/40
Filed: 1995-02-06
Abstract: PURPOSE: To easily discriminate the erroneous operation of a user and a true fault by counting the abnormal signal from a corresponding line state circuit end transmitting a fault alarm when the count value reaches a preliminarily determined count value. CONSTITUTION: When a line interface 11-0 is in its using state, the state of a signal '1' is transmitted from the incoming call detection part and the signal is supplied to an AND circuit 212 and a NOT circuit 214. For the period when the state of the signal '1' is continued, the circuit 212 makes the pulse from a pulse oscillator 211 pass and the number of the passed pulse is counted by a pulse counter 213. At this stage, when the pulse frequency of the oscillator 211 is set to one pulse for every 10 seconds and the line interface 11-0 is continuously used for 38 seeds, the count number of the counter 213 becomes 3. This count value is successively supplied to a comparator circuit 215 and is recorded, the value is compared with preliminarily set maximum and minimum allowable values.  If the values are within the range, a normal signal is transmitted, and if the value becomes the outside of the allowable range, an abnormal signal is transmitted.
