Title: Transmission line diagnostic equipment
Inventor: NARABA KEIZOU
IPC: H04L12/28
Filed: 1992-11-04
Abstract: PURPOSE:To allow a user to cope with an error quickly by diagnosing a normal state or an error depending whether or not a succeeding reception signal is arrived within a permissible delay time during the reception of a preceding reception signal and outputting error information while distinguishing a line length difference error from a line broken error. CONSTITUTION:An error diagnostic section 22 receiving a diagnostic execution command from a diagnostic timing transmission section 20 extracts a permissible delay time from a permissible time memory 14, and decides the presence of an error based on an arrival time difference given by a time difference detection section 17. When a succeeding reception signal (b) is received while a preceding reception signal (a) is received, the diagnostic section 22 diagnosing an error diagnoses the error to be a line length difference error. Furthermore, the diagnostic section 22 diagnoses the error to be a line broken error when the signal (b) is not obtained regardless of the lapse of the permissible delay time during the reception of the signal (a). Thus, the error is quickly coped with by outputting the result of error diagnosis while distinguishing the transmission line length difference error from the line broken error.
