PURPOSE:To improve the utilizing efficiency of a memory and the operation of the titled system by registering a special code in an address of a RAM accessed from a terminal CONSTITUTION:When a caller terminal, e.g., a terminal 11 depresses trunk line buttons 91-95 or an extension button 10, a control line 6 detects it, acquires an external line 31, controls a cross point 5 to connect the terminal 11 and an external line 31. Then, when an abbreviation dial is inputted by using a key pad 8 of the terminal 11, a CPU61 of the circuit 6 recognizes it, accesses a RAM 63, reads a dial number from the abbreviation address and sends it to the external line 31. In when an abbreviation dial is inputted from the terminal 11 after the external line 31 is acquired again, the CPU61 reads the special code registered in the abbreviation address of the RAM63, reads the content of the address and sends it to the external line 31, the memory dial after the specific code is real and sent to the external line 31.
