摘要： A single ended, frequency domain reflectometry signal processing based scheme measures loop loss of a telecommunications wireline. A distortion-corrected, normalized data array is differentially combined with an associated set of wireline noise spectrum values. The resulting noise margin data is processed by a Shannon Theorem operator, to produce a set of N frequency bins, each containing the number of bits which the link will support for a respective tone. The bit contents of the bins represent a composite bit rate that is available for use for ADSL signalling.

摘要： A method and apparatus for automated sectionalization of a DS1/DS3 data path based upon information received at a single location along the path. A test and monitor device is located at a point of demarcation between an LEC and an IEC. A Remote Module is located at a point of demarcation between the LEC and CPE. The test and monitor device is fully ANSI compatible. The information that is received is processed in a three step process in order to generate a "Sectionalizer Report". In preparing the Sectionalizer Report, the information output from a filter is used to determine where particular Events originated. A Remote Alarm Indication-Customer Installation signal is generated to enhance the ability to sectionalize the data path.

摘要： An environmentally protected electrical socket and plug assembly retains environmental security throughout repeated connections and disconnections. The socket and plug assembly includes a socket containing an electrical conductor and adapted to insertably receive a plug, an environmental sealant at least partially filling the socket so that the sealant is at least partially displaced from the socket when the plug is inserted into the socket, and an elastomeric containment means for containing displaced sealant when the plug is inserted into the socket and for urging the sealant back into the socket when the plug is removed.

摘要： A test system for local subscriber lines, which is used with a telephone communication system having a central office exchange, local subscribers accommodated by the central office exchange, and intervening units, i.e., a central office terminal, a subscriber side remote terminal, and a transmission line connected therebetween. This test system carries out a remote test and a local test independently by using a test line connected between remote test equipment and the remote terminal in which an artificial off-hook creation unit is introduced. This unit is made active when a local test is carried out for each subscriber line, to thereby avoid an occurrence of errors in the remote test.

摘要： A circuit arrangement is disclosed by which one of two subscribers (T1, T2) can be connected to a subscriber line (ASL) of the public telecommunication network if a device (2) associated with both subscribers (T1, T2) experiences trouble. The two subscribers (T1, T2) are, in normal operation, both connected to the subscriber line (ASL). Transmission of the signals takes place in this case between the device (2) and an office of the telecommunication network digitally over the subscriber line (ASL). In the event of a disturbance, one subscriber (T1) can be connected by a bypass line (8) to the office with analog signal transfer.
