1. In a digital loop transmission system including a local area network comprising a plurality of remote terminals, each having a preset unique multi-byte serial number, and at least one master circuit in one of said terminals, a method for assigning addresses to said terminals comprising the steps of:

  • generating a search address by each of said terminals which search address has a lesser number of bytes than the serial number;

    performing a binary search by the master circuit to determine the search address of each terminal wherein the master circuit sends a range of search addresses to remote terminals, each remote terminal with a search address within that range responds to the master circuit, and the master circuit divides the search range until it receives a single response from a remote terminal with a search address within the transmitted range; and

    assigning to each remote terminal by the master circuit an active address which is different from the search address and also has a lesser number of bytes than the serial number.
