International Classification:

H04W 4/00
G10L 19/14
H04L 12/56

US Classification:

370328, 704205, 370401, 704E19008

Abstract:

According to one embodiment, a communication network includes an analog voice bridge coupled to two secure network domains that each have a differing security level. The analog voice bridge includes two codecs that are coupled together through an analog voice line that transfers analog voice signals. The analog voice bridge is coupled to each secure network domain through a network switch that transfers data packet streams from their respective networks to the codecs while restricting data packets that are not associated with the data packet stream.

US Classification:

370352

Abstract:

According to one embodiment, a communication system includes an analog voice bridge coupling one secure network domain to another. The analog voice bridge includes two codecs that are each coupled to a secure network domain and to each other through an analog voice line. One codec decapsulates an analog voice signal from a digital voice stream received from a terminal, and transmits the analog voice signal to the other codec through the analog voice line. The other codec encapsulate the analog voice signal in another digital voice stream and transmit the encapsulated digital voice stream to another terminal coupled through the other secure network domain. The analog voice line conveys the analog voice signal from the first codec to the second codec while restricting communication of the digital packet stream between the two secure network domains.

Abstract:

According to one embodiment, a computer system executing a computer program is coupled to multiple secure network domains configured in a multi-level security architecture. The computer program simultaneously establishes a voice connection with a first terminal configured on a first secure network domain and a second terminal configured on a second secure network domain. The computer program may then selectively couple an electroacoustical transducer to the first terminal or the second terminal, and generate an indicator on a user interface indicating the security level of the selected terminal.
