Abstract: A line-conditioning test unit query system automatically queries direct access test units of respective telephone facilities that are used for conditioning and testing telephone lines, to obtain data representative of usage by the test units. A centralized usage tracking or polling processor is programmed to execute a polling routine, which sequences through dialing directory listing each test unit of the network. The polling processor generates tone signal-formatted commands to which the test units respond with synthesized voice messages containing usage parameter data. Using a speech-to-text conversion operator, the routine converts synthesized voice responses from the queried DATUs into digital data for storage in a relational database, from which usage reports are derived.
