Analog Voice Bridge
First Claim
1. A communication system comprising:
- a first codec configured in a first computing system, the first codec coupled to a first terminal through a first packet network and operable to decapsulate an analog voice signal from a first packet stream received from the first terminal; and
a second codec configured in a second computing system that is separate from the first computing system, the second codec coupled to a second terminal through a second packet network and the first codec through an analog voice line and one or more signaling lines, the first packet network and the second packet network are configured in a multi-level security (MLS) architecture, the first packet network having a security level that is different than the security level of the second packet network, the second codec operable to;
encapsulate the analog voice signal in a second packet stream and transmit the second packet stream to the second terminal;
the analog voice line operable to;
convey the analog voice signal from the first codec to the second codec while restricting communication of the first packet stream with the second packet network or the second packet stream with the first packet network;
the one or more signaling lines operable to;
convey control signals associated with the analog voice signal, the signaling lines being decoupled from the first packet network or the second packet network.

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.

12. A communication method comprising:
-
decapsulating, using a first codec, an analog voice signal from a first packet stream transmitted over a first packet network by a first terminal; transmitting the analog voice signal over an analog voice line to a second codec, the analog voice line restricting transmission of voice data packets between the first packet network and the second packet network; and encapsulating, by the second codec, the transmitted analog voice signal in a second packet stream, and transmitting the second packet stream to a second terminal through a second packet network. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
