A portable, automated telephone line test device includes a test module which applies test signals to a telephone line to be tested and detects electrical characteristics of the telephone line, and a user interface module. The user interface module includes a microprocessor, a display, a keyboard and a program memory in accordance with a standard microcomputer architecture. The processor of the user interface module is programmed to control the test module to perform a pre-programmed sequence of tests. The display provides indications of the tests being performed. The programmed sequence is varied by the device according to test results. Depending on the results obtained, the device also provides interpretative diagnostic messages and instructs the user to carry out additional test procedures.

Automated telephone line test apparatus with intelligent diagnostic function

The invention relates to a device and a method for testing of telephone a subscriber loop/access line using a central test head and a series of remote test devices. In this case, the test head sends a telephone call to a remote test device, the test device contains a caller identification circuit and micro controller designed to recognize telephone calls from the test head. Therefore, when this remote test device receives this call, it disconnects an attached telephone and it signals a test and measurement circuit to start conducting a test(s) with the test head. This series of tests could be used, as an example, to determine whether there is excessive circuit loss, C-notched noise, C message weighted noise or 3 Khz flat noise on a subscriber loop/access line. This testing device could save an access provider from having to send a representative to the customer/subscriber locations to test the subscriber loop/access line.
