Abstract

PURPOSE:To realize a combination between the general circuit and the public circuit without worsening the call loss and the attenuation distortion by providing the next incoming trunk monitor means into the trunk within the public charging local trunk. CONSTITUTION:Pattern ''3'' in the Karnaugh map shows the case in that the outgoing connection call is connected to outgoing trunk OGT9 via the loop around connection. In this case, incoming trunk ICT of the next station connected to OGT via the trunk line is monitored by next ICT monitor relay 17 which is provided within public charging local trunk IOT-CH8. As a result, next ICT monitor function which is so far provided within OGT can be omitted, and furthermore preceding monitor function 1 and call capacitor 3 are provided also within IOT-CH. Thus, a perfect pattern can be formed at the OGT side, improving the call loss and the attenuation distortion.
