Abstract

PURPOSE:To enable the bracketing of communication blocking factors, by sequentiall checking from lower hierarchy and giving correct data only to upper hierarchy for check, in a communication network in which data transmission and reception is made according to the protocol with hierarchy. CONSTITUTION:In a data communication newwork having a protocol with hierarchy, a signal flowing on a transmission line SLN and each frame including the data are monitored, and verification is made from the protocol of the level at the least hierarchy sequentially, and correct information only is given to the upper ranking protocol verification function. Thus, whether the communication failure factor between devices MD1, MD2 of the data communication network is at a public backet exchange network PKTN side, data terminal PT side or transmission line SLN, can be bracketed, and the detection of error, display and failed production data can be outputted with the protocol verification function at each hierarchy can be outputted even to the high speed and intelligent terminal of computers, etc.
