ABSTRACT:
For enabling to obtain automatically a proper identifier of a remote terminal and to assign an identification number to the remote terminal in order to performing supple communication control of a data transmission system wherein upward communication is performed according to a TDMA system and downward communication is performed according to a TDM system making use of cells having fixed length; a local station of the system comprises: a command-cell generation timer (112) for generating a command-cell generation trigger periodically, a command-cell generating unit (113) for generating a command cell to be downward transmitted every time the command-cell generation trigger is supplied by writing an available identification number therein, a window generation timer (111) for enabling a window signal every time the command-cell generation trigger is supplied for inhibiting transmission of upward cells from the remote terminals whereto identification numbers are assigned, a control-data-cell generating/terminating unit (107) for detecting a newly installed remote terminal by receiving a control data cell during the window signal is enabled, wherein a proper identifier of the newly installed remote terminal is written, and a terminal management unit (109) for assigning the available identification number to the newly installed remote terminal.
