REMOTE MEASUREMENT UNIT WITH INTEGRATED LINE MEASUREMENT AND CONDITIONING FUNCTIONALITY

摘要

A processor-controlled integrated telephone line measurement and conditioning apparatus installable at a remote site provides a multiplicity of measurement and conditioning functions that are selectively executable in response to commands issued from a supervisory command site. The dual measurement and conditioning capabilities of the architecture of the present invention impart both virtual remote measurement unit (RMU) functionality and virtual metallic access unit (MAU) functionality that may be individually accessed and controlled. The RMU operates primarily as a test head that performs mechanized loop testing (MLT) tasks, while the MAU is operative to impart prescribed electrical conditions to a specified line circuit. When controllably accessed to operate as a virtual RMU, the present invention responds to instructions from a command site (loop maintenance operations system) and performs single-line demand tests on a line provided by a pair gain system. To operate as an MAU, the system receives commands from a direct access test unit (DATU) and performs line conditioning functions on the test line provided by the pair gain system.
