摘要:
A communication network including connection switching exchanges, such as an ATM, a connection management apparatus is provided in a network management unit of a communication network. A group of logical connections with a fixed group size and consecutive identifiers assigned to the connections is treated as a unit. The number of logical connections in the group is an integer with a power of 2. The logical connections and connection identifiers assigned to the logical connections are set up and released in connection setting units each equal to a multiple of the group size in a unitary manner across the network. A priority level is assigned to each connection setting unit. When logical connections have been set for connection setting units sharing the same connection identifiers, logical connections with the shared connection identifiers pertaining to a connection setting unit with a smaller size is considered to be valid.

In a communication network including connection switching exchanges such as an ATM, a connection management means is provided in a network management unit of the communication network. A group of logical connections with a fixed group size and consecutive identifiers assigned to the connections is treated as a unit. The number of logical connections in such a group is an integer with power of 2. Logical connections in the communication network and connection identifiers assigned to the logical connections are set up and released in connection setting units each equal to a multiple of the group size in a unitary manner across the whole communication network. A priority level is assigned to each connection setting unit. When logical connections have been set for a plurality of connection setting units sharing the same connection identifiers, logical connections with the shared connection identifiers pertaining to a connection setting unit with a smallest size is considered to be valid.

In a communication network constituted of relay nodes and edge nodes interconnected by communication lines and a network manager, the network manager manages relay nodes and edge nodes connected to the network manager by operation management communication lines. The network manager requests to set a logical connection between an ingress and an egress of the connection, and in response to this request, relay nodes and edge nodes set a logical connection specifying at least one of a transmission source and a destination.

An instruction acceptance program is provided which is capable of saving time and labor required if a user has to choose a driver individually when choosing and executing either faxing or printing. This instruction acceptance program is used for allowing: a display control portion to display, in a display portion of a personal computer, a processing choice message which prompts the input of an instruction to execute either faxing or printing (Si); and an acceptance portion to accept the instruction to execute either faxing or printing.
摘要:
An echo suppressor for a communication system wherein a signal sent to a transmitting line is returned to a receiving line with some delay. The suppressor comprises an attenuator for attenuating the amplitude of a received speech signal. The transmitting speech signal amplitude level is compared to the amplitude of a receiving speech signal, and according to the result obtained, a signal for controlling the signal attenuation of the attenuator is generated. The delay time, until the attenuation control signal operates on the attenuator according to a change in the amplitude level of the receiving speech signal, is controlled. The controlled delay time is normally held at a predetermined maximum value, and is minimized when a change in amplitude of the receiving speech signal indicates a beginning of speech. Thus, an echo of the speech uttered by a near end user can be suppressed without impairing a beginning of the speech signal uttered by a far end user.

A method and apparatus for speech signal detection and classification in which a partial auto-correlation and residual power analyzation circuit extracts a normalized first-order partial auto-correlation coefficient and K.sub.1 a normalized zero-order residual power E.sub.N from an input signal, and a sound source analyzation circuit extracts a normalized residual correlation .phi. from the input signal, and in which on the basis of these extracted parameters, speech signals are detected, and, when so detected, the detected speech signals are classified into a voiced sound V, an unvoiced sound U and silence S. The classification of the respective voiced sound, unvoiced sound and silence is determined on the basis of preset threshold values that are mutually considered and which correspond to values of these extracted K.sub.1, E.sub.N and .phi. parameters for establishing boundary values for classifying the input signals into a voiced sound, an unvoiced sound or silence.

摘要:
A bidirectional communication system in which dial-up connection for transmitting communication data may be disconnected when not used, and may be insured to be reconnected when needed. Also, the system includes an arrangement in which availability of connection with dial-up may be notified/determined in advance. The bidirectional communication system includes a first communication station and one or more second communication stations, the second communication stations receiving information delivery service from the first communication station, and the second communication stations performing data communication with the first communication station by means of dial-up link. The first communication station includes: an assignor assigning to the second communication station a protocol identifier of a network layer; a connector/disconnector for connecting/disconnecting the communication link according to respectively the presence and absence of communication data from the second communication station; and a storage holding the protocol identifier of the network layer assigned to the second communication station during the information delivery service from the second communication station.
摘要:
In a subscriber information service system including a plurality of terminal equipment, and an information server for presenting personal information of a called subscriber to user at each of the terminal equipment, the information server being connected to the plurality of terminal equipment through a communication network, the information server has a subscriber information table consisting of a plurality of personal records each including a personal identifier assigned to a subscriber, a name of the subscriber, status information of the subscriber, and a name and an equipment address of the communication equipment which can be utilized by a user, and a facility of transmitting content data of the personal record of the specific subscriber registrated in the subscriber information table to each of the terminal equipment. Prior to the communication with the called subscriber, the user at each of the terminal equipment requests the information server to transmit the personal record of the called subscriber, and determines both the status of the called subscriber and the optimal communication equipment by referring to the contents of the personal record received from the information server.
