Method for accessing address identifier of communication subscriber

PURPOSE: To increase the accessing speed to the address identifier of a communi cation subscriber by providing first and second contracted address areas on a table and labeling the presence of addresses with bits. CONSTITUTION: A transmission address SA and a target address DA are given to a data packet and separately retrieved. Entries from '0' to '2047' are provided for table addressing and an memory address is indicated together with its number and offset. A list L1 shows an address to be processed and the offset indicates the address offset from a second address. In addition, different offsets are set at every table and each table is successively accessed through the offsets. Therefore, the accessing speed to the address identifier of communication connection filed on a table can be increased. COPYRIGHT: (C)1995,JPO
