Title: Isdn communication system
Inventor: ASANO KIMI
IPC: G08C19/00
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To prevent interferences with communication performed by a demander and further to attain cost reduction by performing communication, while connecting a center and a meter through an ISDN public line and writing prescribed information in the user of call control message and a user information area by using only a D-channel between the center and the meter. SOLUTION: When a center 3 transmits a meter-reading request telegraphic message or the like to a line IF 5, the line IF 5 transmits this message, while using the D-channel of an ISDN public line 7. At that time, the center 3 sets a start telegraphic message or the like to the user/user information (UUI) of SETUP message and sends it through an I-NCU 11 to a gas meter 13. When the meter-reading requests telegraphic message or the like is received, the gas meter 13 turns a gas meter-reading value or the the like into a response telegraphic message, sets this message to the UUI of I-NCU 11 or DISC message, sends it to the line IF 5, while using the D-channel and disconnects the line. Thus, the center 3 can perform low-cost automatic meter-reading through the line IF 5, based on the response telegraphic message.
