摘要： Method for registering an overload situation in a telephone exchange system comprising a local exchange (LE), an access node (AN), a concentrating interface (V5) connecting the access node (AN) to the local exchange (LE), a resource manager (RMA), which is part of the local exchange (LE) and a statistical unit (STU), which is part of the local exchange (LE). The method comprises the steps of scanning the concentrating interface (V5) to find a free time slot and detecting by means of the resource manager (RMA) that the concentrating interface (V5) is overloaded. The method further comprises the steps of sending to the statistical unit (STU) a message reporting congestion, based on information existing in the resource manager (RMA), and recording the congestion situation into a traffic measurement report by means of the statistical unit (STU).

摘要： A communication company accumulates a communication time or the amount of communication for a call when the call is received, and provides additional service such as discount for a called party according to an accumulated communication time or the accumulated amount of communication. Another example of additional service is discount made according to whether a first communication company providing communication service between a called party and a first switching office and a second communication company providing communication service between a calling party and a second switching office are identical.

摘要： A frequency domain reflectometry-based bridged tap detection system for a telecommunication wireline employs a prescribed filtering operator, such as a nullbest-fitnull curve filter or a piecewise high pass filter bank, upstream of a Fourier processing operator, to improve the signal-to-noise ratio of the digitized amplitude array of the swept frequency band. To fit the response tones within the dynamic range of the analog-to-digital converter that digitizes the response tones detected from the wireline, a signal conditioning circuit, comprised of a comb filter bank, envelope detector and compander, is installed between the test head and the input to the analog-to-digital converter.

摘要： In a system and method for determining the suitability of a copper pair line for xDSL service use, characteristic parameters of a copper pair line to be tested are measured. These characteristics include a wire gauge, length, and temperature of the copper pair line. In addition, characteristics such as the presence of short circuits, longitudinal balance, the presence of load coils, wideband noise and loop attenuation are tested for the copper pair line. A plant map of the copper pair line is then determined based on the measured and tested characteristics. Using the above characteristics and the plant map of the copper pair line, a transfer function representative of the plant map is determined which is then used to analyze and thereby qualify the copper pair line.

摘要： A communication network (10) utilized for providing communications between a first party and a second party includes a surveillance server (26) within a core network (10) to provide communication surveillance capability. The core network (10) may be a packet data network, and the surveillance server (26) is operable responsive to trigger information to establish communications surveillance. Communication surveillance may be established by creating duplicate bearer packets of those data packets carrying the communicated data between the parties, creating duplicate control packets of those data packets carrying in-band or out-of-band call control information between the parties and within the packet data network, and/or various combinations thereof. The duplicate bearer packets and the duplicate control packets are routed to appropriate authorized law enforcement agencies for providing surveillance.

摘要： A network interface circuit employing differentially driven capacitive couplings across a high voltage isolation boundary and in which a null/null CODEC is positioned on the line side of the high voltage interface. In this manner, only four wires cross the high voltage boundary, namely differential pairs for transmit data and receive data. The transfer functions for setting AC and DC parameters, such as impedance matching, are provided by digital filters. Further, with the CODEC on the line side of the high voltage isolation interface, the data which crosses the interface is modulated at the null/null data rate and, thus, capacitive coupling can be used across the high voltage isolation boundary without the loss of DC data.
