IPC: H04L12/437
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To allow any communication station to act like a transmission station and to attain multiple address transmission from a transmission station by allowing a communication station failed in transmission to inform fault information to all communication stations via a communication station at an opposite side. SOLUTION: Communication stations (a)-(f) possibly acting like a transmission station are coupled in a loop by a full duplex communication line 20. Each communication station is provided with reception sections 1, 6, transmission sections 2, 7, and a control section 3. When a communication station receiving transmission data cannot send data to an adjacent communication station, the communication station unable to send the data informs fault information to all the communication stations via a communication station at the other side. Thus, each communication station recognizes where the communication is interrupted, transmission data are sent in other loop and then sent surely.

Abstract: PURPOSE:To facilitate the input of a telephone and to prevent a mistaken call and a malicious call by automatically recognizing the number string of a telephone number by means of reading a bar code so as to automatically execute oscillation. CONSTITUTION:The telephone number shown by the character string of about ten digits is made into the bar code so as to print it.
