摘要： A system and method for designing a dial plan for Voice over Internet Protocol (VoIP) systems includes generating an abstract dial plan design which is platform independent, the dial plan including rules for routing communications in a VoIP network structure. The dial plan is validated through simulations prior to deployment to evaluate the dial plan performance under simulated conditions. The dial plan design is translated to provide compatibility with a deployed network using platform specific configuration adaptors.

摘要： A method characterizes a customer line for data transmission. The method includes measuring electrical properties of the customer line from a central location, identifying a line model from the measurements, and identifying a modem model for a modem selected for use with the customer line. The modem model gives performance data for the selected modem. The method also predicts performance data for the customer line when operated with the selected modem by combining the line and modem models.

摘要： Disclosed are an exchange which performs call connection control for subscribers in a plurality of areas having different toll numbers, and a method of controlling connection of calls in this exchange. A telephone number translation table is created in accordance with a telephone number structure comprising an internal toll number and internal local office numbers, wherein the internal toll number is a string of numerals shared by toll numbers in the plurality of areas, and the internal local office numbers are numbers obtained by adding a number, which is not shared by the toll numbers in the plurality of areas, onto the beginning of local office numbers that follow the unshared number. The exchange performs switching service control using the telephone number translation table.

摘要： There is provided an electronic inductance circuit having a transistor, a first resistor, a second resistor, a capacitor and a first current source. The main current path of the transistor and the first resistor are connected in series to form a first serial circuit between an input terminal and an output terminal. The second resistor and the capacitor are connected in series to form a second serial circuit between the input and output terminals, thus forming a parallel circuit of the first and second serial circuits. The connection point between the second resistor and the capacitor is coupled to the control terminal of the transistor. The connection point is connected to the first current source for determining the operating point of the transistor.
