<p>PURPOSE:To provide a buffer address management method in which a buffer address including a large scale error and buffer addresses in duplicate are detected. CONSTITUTION:An address operating state table registering the operating state of all buffer addresses in existence in an exchange is provided in an operating state storage section 21 to grasp which buffer address is actually in existence in a common buffer memory of the exchange and in which queue the address is at present in existence. A non-existence buffer address including a bit error is detected by the retrieval operation of an address operating state table in state check sections 22a, 22b. Furthermore, before the buffer address is stored in an idle address queue 10 and stored in an address queue 11, a state value by the state value check section is referenced and a default state by state registration sections 24a, 24b is fixedly registered.</p> |
