Abstract

PURPOSE:To obtain a common line signal information collection and analysis method independently of the type of exchanges without giving any effect onto a processing capability of the exchange main body by monitoring a common line signal from a common line signal monitor terminal of the exchange or a repeater and extracting only a signal in matching with desired information. CONSTITUTION:Common line signal information is extracted from monitor terminals 11 to 13 of an exchange in plural exchange accommodation buildings 10. An adaptor 14 receives the information of planes A, B of the monitor terminals 11 to 13. Usually each 50% of the both is received and when one information is in error, 100% of the other information is received. Then the adaptor 14 is used to monitor call connection information from the monitor terminals 11 to 13 of the subscriber exchange or the common line signal monitor terminal of the common line signal repeater and extracts and processes only the required information signal. The extracted signal is sent to an analysis center through a communication channel 31 and required information is processed and outputted by a computer in the analysis center.

2. Description of the Related Art In a public communication network or a private line network, the communication status of each line is grasped, for example, which direction of communication is most frequently used for each communication ground or exchange area, traffic information for each hour,
Ascertaining the presence / absence of a congestion time zone is important for operating a communication network as a telecommunications carrier. Conventionally, as a method for grasping the communication state of each line, a method of directly connecting a monitor device (for example, a recorder or the like) to the line and operating the monitor device for a required time to analyze the extracted data is available. is there. However, this method has the following problems. Since a monitor device is physically connected and extracted for each required line, it takes time to set up the device, and if the number of monitor devices is limited, the measurement line will be limited. Since the measured data is brought to the analysis center for analysis processing, it takes time and effort for analysis. Further, as another conventional method, there is a method of transmitting the call information generated in the exchange to the processing center using the common line signaling network after performing the normal connection processing. However, this method also has the following problems. Since the exchange uses the common line signaling network to transmit, the load on the processor of the exchange is increased, and since the measurement data is transmitted using the common line signaling network, the transmission load on the common line signaling path is increased. Interface devices, processing devices, etc. depend on the type of switchboard, and have low flexibility in extracting and analyzing various types of information included in call information.
