Dual port interface for communication between a voice-over-data system and a conventional voice system
First Claim
1. A communication apparatus, comprising:
- a data interface;
first telephone line interface means for connection to a first telephone line;
second telephone line interface means for connection to a second telephone line;
voice conversion means for converting incoming digital voice data into outgoing voice signals and for converting incoming voice signals into outgoing digital voice data;
voice compression means coupled to the voice conversion means for compressing the outgoing digital voice data into compressed outgoing digital voice data and for decompressing compressed incoming digital voice data into the incoming digital voice data; and
main control means coupled to the voice compression means, the voice conversion means, the data interface, the first telephone line interface means and the second telephone line interface means, forreceiving and demultiplexing the compressed incoming digital voice data and first computer digital data from the first telephone line interface means from the first telephone line,transmitting the first computer digital data to the data interface,passing the compressed incoming digital voice data to the voice compression means and transmitting the outgoing voice signals from the voice conversion means to the second telephone line interface means for transmission on the second telephone line,receiving the incoming voice signals from the second telephone line interface means from the second telephone line, passing the incoming voice signals to the voice conversion means, and obtaining the compressed outgoing digital voice data from the voice compression means,receiving second computer digital data from the data interface, andmultiplexing and transmitting the compressed outgoing digital voice data with the second computer digital data to the first telephone line interface means for transmission on the first telephone line.

Abstract
A personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. The personal communications system is equipped with two telephone line interfaces to allow connection between two remote sites. The connection between the first remote site and the local site may operate in a voice over data communications mode to simultaneously send compressed voice and data. The connection between the local site and a second site is a voice only connection allowing the first remote site to talk to the second remote site without breaking the data communication connection between the first site and the local site. The second remote site may be a public telephone network. The communication between the first remote site and the second remote site through the local site may also be a data communication connection, or it may also be a voice over data communication connection.
