Abstract
An audio communications device adapter connects a plurality of audio communications devices, such as headsets, to digital data paths, such as T1 or E1 data paths in a telephony system. The adapter comprises one or more analog audio signal connectors that connect to analog audio signal paths coupled to the audio communications devices for receiving and transmitting outgoing and incoming analog audio signals. The adapter also includes a digital data connector for connecting to digital data paths to transmit and receive outgoing and incoming digital data streams containing digital encoded audio signal data. A digital data formatter coupled to the digital data connector extracts the incoming digital encoded audio signal data from the incoming digital data stream and formats the outgoing digital encoded audio signal data. The digital data formatter includes a T1 framer and interface, serial PROMs for programming the T1 framer and interface, timing and control circuits, and a T1 transmit equalizer. An audio signal converter coupled to the analog audio signal connector and to the digital data formatter converts the outgoing analog audio signals into the outgoing digital encoded audio signal data and converts the incoming digital encoded audio signal data into the incoming analog audio signals. The audio signal converter includes a plurality of codec circuits.
