Method for automatically obtaining topological relation of telecommunication device

The present invention discloses a method of automatically obtains topology telecommunication device, the steps comprising: a main control board to the other board telecommunication device identification broadcast present logic board; telecommunication device of other boards within the received logical identification main board , reported the identification information of each logic board to the master; the logic-identification information reported by the telecommunication device according to the master board logic boards and other boards identifier generated topology FIG. The present invention is notified by the main control board to the other board logic identifier, and generates a topology diagram of logic-identification information reported by other boards, the whole process without human intervention, and therefore more quickly and accurately.
