ABSTRACT:
A diagnostic system comprises a plurlity of remote computers connected to a switched telephone network to which a diagnostic center and an adminstrator's station are also connected. The diagnostic center includes a data processor for preparing a diagnostic file for each of the remote computers and storing it into a first memory. Each diagnostic file contains a remote computer's identification, a remote computer's telephone number, diagnostic commands, expectation values and an administrator's telephone number. The center transfers files from the first memory to a second memory and sequentially recalls data in each file in the second memory. The center first sends dialing information to the network according to the recalled computer's telephone number to establish a first path to a computer identified by the recalled identification and then sends out test signals according to the recalled diagnostic commands to the identified computer to detect responses from it. If there is a match between each response and each recalled expectation value, the first path is released and a new path is established to the next remote computer. If there is a mismatch, the first path is released and a second path is established to the administrator's station and contents of the mismatch and the recalled identification are sent to the administrator's station to notify abnormalities.
