摘要： PURPOSE:To suppress the fluctuation of the load on a signal source, by receiving a continuous call signal and an intermittent pattern, and interrupting the continuous call signal in accordance with the intermittent pattern. to transmit the interrupted call signal to a subscriber line. CONSTITUTION:A storage circuit 10 stores the type of call signal which is to be transmitted by a subscriber circuit in response to the type of call connection to plural subscriber circuits. An intermittent patter signal producing circuit 12 produces a signal corresponding to the intermittent pattern of each type of call signal. A data distributing circuit 14 receives a continuous call signal produced from a signal source 2 and an intermittent pattern and interrupts the continuous call signal in accordance with the intermittent pattern to transmit the interrupted call signals to subscriber circuits 30-3n. Thus an increment of types of call signals receives a control of phase by a phase data which is autonomously produced by a hardware to cope with a change of the intermittent pattern. In such a way, the fluctuation of the load on the signal source 2 is suppressed.

摘要： PURPOSE:To improve the effect of line concentration, by providing a means which performs time division line concentration for subscriber terminals and a means which performs time division line concentration after the subscriber terminals are spatially divided and line-concentrated. CONSTITUTION:A line concentrator consists of telephone sets 1-1-1-k with a low call rate, a subscriber 4 of a high call rate, a spatial division line concentration switch network SD NW, mixed line concentration trunk circuits TC1- TCl, time division line concentration subscriber circuits SCA-SCC, and a time switch T. When single subscribers 1-1-1-k of a low call rate make calls, a central processing unit CC gives an instruction to a line concentration controller CONT to connect the subscriber and the trunk circuit TCl with the network SD NW. A P time slot on a digital highway is connected with the time switch T. Thus, the telephone set 1-1 is connected to a dial register circuit via a time division switch network.

摘要： PURPOSE:To realize easily the electronic ring trip function of the ring trip system of a telephone switchboard by periodically detecting a call signal voltage at a constant voltage level point which is higher than a call signal voltage at the off-hook time and lower than that an on-hook time. CONSTITUTION:In the ring trip system which discriminates whether a called subscriber answers or not by sending out a call signal from ringing-tone source IR to telephone set SUB of the called subscriber, level detector AA is connected to resistance R0 via tone source IR so as to detect voltage levels of subscriber's lines L1 and L2 at the periodical point in time when the call signal from tone source IR constant in level. Further, this system is equipped with guard timing supply circuit MM which detects the malfunction of detector AA judging from rush current generated at lines L1 and L2 when a trunk pattern is changed over, and zero-cross circuit BB and AND circuit LL which detect the periodical point when the call signal from tone source IR becomes constant in voltage level, thereby constituting the ring trip system.

摘要： PURPOSE:To prevent the latency of an on-stack trouble by setting a loop by a tested path and an interrupt path and supplying a two-way voltage and a detecting whether the loop current is flowed or not under the state where off instructions are issued to a switching element in each stage. CONSTITUTION:A testing loop is set by trunk TRK, switch cross points and interrupt cross points of network NW, and testing circuit TST, and floating current sources CSA and CSB which can switch the currnet direction and current detector circuits ICKHA and ICKHB are provided in TST, thereby making two-way current supply possible. Then, cross points of NW are turned OFF in order from the first stage; and the current is flowed in the testing loop to detect the loop current when a cross point which should be in an OFF-state is in an ON-state, and this cross point is decided to be an on-stack trouble.
