Path connection, telephone control, and transmission / reception / storage of voice and information data to / from FAX or PC via adapter.
[0005]
Conventional key telephone systems are disclosed in, for example, Japanese Patent Laid-Open Nos. 7-95638 and 9-116625. In these conventional key telephone systems, noise generated at each connection interface between the key telephone main device and the telephone, adapter, office line, and dedicated line as CTS system components becomes a problem. Therefore, the key telephone main unit software monitors and detects unauthorized interface operations and noise generation, and resets the CTS system components when they occur. As a result, the key telephone system is restarted and the key telephone system is prevented from being out of control.
[0006]
Key phone main unit software's noise judgment criteria are data analysis of response data received via interface board, data fraud determination, occurrence of noise due to receiving data outside expected code, and recovery from noise occurrence state It is a judgment. This noise determination process is not a discrimination for each device connected as a CTS system component device but a uniform determination criterion. In addition, since this determination process is performed for all interfaces, there is a drawback that the processing capability of the key telephone main unit software decreases when the number of CTS system components connected is increased.
[0007]
A conventional Pkg interface procedure is shown in FIG. FIG. 5 shows a Pkg interface procedure between the key telephone main unit software 201, Pkg 202, and telephone 203. In other words, this is an example of an interface between the telephone 203 and the Pkg 202 that is a board for executing an interface with the telephone 203. In FIG. 5, the key telephone main unit software 201 monitors the response data received from the Pkg 202, analyzes each data, determines whether or not the data is illegal, and determines whether noise has occurred or recovered. Processing contradiction occurred due to a state mismatch with Pkg202.
[0008]
[Problems to be solved by the invention]
In the conventional key telephone system, the key telephone main unit software and the CTS system component device are inconsistent, and the operation of the key telephone system is stopped. Further, in the office line and leased line control, there is a possibility that the user will be burdened with an expensive line usage fee while remaining in the line supplement state. Further, it is not possible to clearly determine whether the noise is secondary noise generated during maintenance work performed by maintenance personnel due to an increase in the number of telephones and office lines or noise generated during normal operation.
[0009]
Therefore, an interface configuration and procedure for maintaining and improving the throughput of the key telephone main unit software is required.
[0010]
