  • Address management for remote terminals in digital loop transmission systems
    Patent number: 5502438
    Abstract: Disclosed is a method and apparatus for identifying remote terminals which are networked in a digital loop transmission system. A Site Interface Unit (SIU) at one of the remote terminals acts as a master. The Bank Controller Unit (BCU) at each remote terminal calculates a 16-bit number based on its 60-byte serial number. A binary search is then performed by the SIU to determine the calculated number of each BCU, and an address is assigned to each remote terminal by the SIU. Any conflicts in the numbers initially calculated are resolved by transmission of the full 60-byte serial number.
