Abstract: PROBLEM TO BE SOLVED: To provide a wavelength division multiplex switch network. SOLUTION: Switch modules (102) of this invention are interconnected via optical links (104) to form an exchange system (100). By using different wavelengths of the optical links (104), communication is selected between the switch modules. The wavelength is assigned for communication between the switch modules constantly or variably. The wavelength is subjected to time division multiplex processing or divided further in partial wavelength. The switch modules are communicated by selectively transmitting/receiving the wavelengths assigned to the optical links.

Abstract: PROBLEM TO BE SOLVED: To efficiently process a client with the high frequency of utilization while surely providing prescribed services to all the clients. SOLUTION: The existence of data call to generate a line with the high frequency of utilization is detected by detecting a response signal (301), testing the signal of tone or the like on the node of that call later (311) and investigating whether the duration of that call exceeds prescribed time or not (315). The line for transmitting or receiving the data call exceeding the prescribed time is monitored for next measuring its frequency of utilization. As a result, the line with the high frequency of utilization can be detected by monitoring only the comparatively less lines for transmitting or receiving the data call.

Abstract: PROBLEM TO BE SOLVED: To provide a system that automatically reassigns an echo canceler to another facility in the case that it is decided that a facility to which the echo canceler has been assigned does not generate vast profit from echo cancelation. SOLUTION: The echo canceling system provided with self-deactivation processing of this invention includes an echo canceler and an echo detector employing an adaptive filter. The adaptive filter decodes an estimate value of an echo signal in existence in an unprocessed signal received from a near-end of a communication channel. The echo detector compares the energy of the unprocessed received signal with the energy of the received signal whose echo is canceled. When the difference is high, the echo canceler is left as active. The difference, that is, the estimated echo energy is small, the echo canceler is deactivated and the echo detector selects the unprocessed received signal as its output. In the case that a plurality of channels for echo cancelation is to be served, the deactivated echo canceler is reassigned to serve for another communication channel.

Abstract: PROBLEM TO BE SOLVED: To provide a remote call direction revision system placed in the inside of a local access network that sets the direction of a data traffic addressed to the internet to a channel directly connecting to the internet. SOLUTION: This call direction revision system has a processing module 134 accessing stored data for receiving protocol information ancillary to a call by a subscriber's equipment. The processing module 134 generates a direction setting message, based on the protocol information and stored data. The call direction revision system is further provided with a direction setting module 136, configured to change the direction of the call from the subscriber's equipment. The direction setting module 136 receives a direction setting message from the processing module 134 and changes the direction of a call to reduce congestion, in compliance with the direction setting message, then the device in the local access network adjusts the call whose direction is changed. Thus, congestion in the inside of the local access network resulting from the data traffic addressed to the internet is reduced.

Abstract: PROBLEM TO BE SOLVED: To surely distinguish a special call such as a data call, etc., from a voice call and to enable proper processing for charging, according to the kinds of call by easily and inexpensively providing superior method and device capable of detecting the specific call such as the data call, etc., in a frequency band on the basis of each call in a telecommunication exchange system. SOLUTION: A data call is detected by detecting a response signal (301), after connecting a tone detector to a call (309) and detecting a characteristic tone to the data call using a tone detector (311). When the tone to the data call is detected, a record for charging the call is marked as a data call (315). Consequently, a charge which is different from that for the voice call is imposed on the data call.

Abstract: PROBLEM TO BE SOLVED: To synchronize the different networks with each other to prevent the call clipping and to improve the call processing efficiency in an electric communication system where the different networks are connected to each other by delaying the message that is received via a virtual transport. SOLUTION: When a subscriber telephone set 112 calls a telephone set 178 and a signal transfer point 140 receives a call establishing signal message, a virtual transport server 150 stores a common channel signal message in a memory 182. When a prescribed time passed, a packet data network 190, i.e., a different network decides the establishment of a voice path between the calling and called sides and transmits a message to perform a call setting operation. Thus, the common channel signal message is delayed to establish a voice path before a call setting process is executed. As a result, the call setting operation is surely attained between the different electric communication network.

Abstract: PROBLEM TO BE SOLVED: To enable access to all the time slots of a TSI by storing a packet in a packet assembler-inverse assembler, transmitting it and directly connecting a processor for inserting the output packet to an output buffer to the memory of the TSI. SOLUTION: A trunk time slot stores a PCM signal 203 and sends the packet to a RAM 211 for assembling/inversely assembling it. A line time slot is sent to a modem signal processor 201, analog PCM data are transformed to digital data to be used for the RAM 20, and the digital data in the RAM 211 are transformed to analog PCM data for transmission to the line time slot. The packet assembled or inversely assembled by the RAM 211 is changed so as to have a data address by a routing processor 213 and stored in a TSI start interface 105. Thus, the ATM network is directly interfaced while using the ATM interface 221.

Abstract: PROBLEM TO BE SOLVED: To apply routing to a call in way of minimizing the cost for the call by deciding selection of a public exchange telephone network trunk line or an internet connection in a calling switching system. SOLUTION: Upon the receipt of a request from a master station 25 to set up connection by a calling switch 1, the switch 1 discriminates whether the call is sent via a telephone long distance network 11 that interconnects a calling long distance access switch 1 and a termination long distance access switch 2 or via the Internet 10. When the calling switch 1 decides on the routing of the call via the telephone network 11, the routing is executed in the conventional manner. When routing of the call is decided via the Internet 10, a series of packets are exchanged between the calling long distance access switch 1 and the termination long distance access switch 2, and the calling switch 1 sends an initial address message including a call identifier 41 to the termination switch 2.

Abstract: PROBLEM TO BE SOLVED: To surely present a prescribed service to all customers and to efficiently process a line of high utilization by providing the excellent method and device which can easily and inexpensively detect the line of high utilization in an electric communication switching system. SOLUTION: The existence of a data call which causes a line of high utilization is detected (311) by testing a signal like a tone on the connection part of this call after detection of a response signal (301). Lines through which the data call is transmitted or received are monitored for the purpose of measuring their degrees of utilization. As the result, the line of high utilization is detected by monitoring only a relatively smaller number of lines through which the data call is transmitted or received.
