Audio Telemetry for a Computer Installation

This article relates to an arrangement for providing a maintenance and repair service for a computer installation located at a distance from a maintenance center (CE Office). The CE Office is connected to the computer installation through a telephone network.

The computer installation is connected to the telephone network through a local private branch exchange (PBX) and is actually coupled to the PBX by means of a Voice/Telephony Adapter (VTA) which effectively converts the computer installation into a telephone extension from the PBX.

The VTA includes a microprocessor and emulates the functions of a push- button telephone. It can call up other telephones by generating dual tone multi- frequency (DTMF) coded signals for the required numbers. It can recognize and respond to incoming calls and can decode incoming DTMF signals. It can perform analog-to-digital conversion on incoming speech and pass this to a storage device in the computer installation. Also, it can perform digital-to-analog conversion on stored digitized speech, thus enabling speech messages to be sent to a remote telephone.

The VTA is used as a means of direct voice communication with thhe CE Office for the purpose of audio telemetry, as illustrated in the figure. This enables the Customer Engineer (CE) to interrogate the computer installation by DTMF signals from the CE Office and the computer installation to give spoken responses. The connection can be established either by the computer installation generating the correct DTMF signals and calling up the CE Office, in the event of failure of the installation, for example, or by the CE calling up the computer installation on an enquiry basis, for preventive maintenance, for example.

The computer installation includes a program called the Audio Reliability Availability and Servi...
