Method and apparatus for bridging concurrent voice and data and SVD communication endpoints
First Claim
1. An apparatus for bridging communications between a first communication endpoint equipped with an Integrated Services Digital Network (ISDN) compliance data circuit terminating equipment (DCE) and a second communication endpoint equipped with a simultaneously voice and data (SVD) enabled DCE, said apparatus comprising:
- (a) first interface circuitry for interfacing with the first communication endpoint;
(b) second interface circuitry for interfacing with the second communication endpoint; and
(c) bridging circuitry coupled to the first and the second interface circuitry for operating the apparatus in one of at least four modes responsive to communication events as well as commands from the first and second communication endpoints, wherein the at least four modes include a first mode where the bridging circuitry bridges neither voice nor data between the first and the second interface circuitry, a second mode where the bridging circuitry bridges voice only between the first and the second interface circuitry, a third mode where the bridging circuitry bridges voice as well as data between the first and the second interface circuitry, and a fourth mode where the bridging circuitry bridges data only between the first and the second interface circuitry.

Abstract
A two way ISDN-SVD bridge is provided to bridge communications between an ISDN and a SVD communication endpoint. The bridge comprises a micro-controller, a data pump, an audio DSP, a CODEC, an ISDN interface, and a DAA. The micro-controller responsive to events and commands from the ISDN and SVD endpoints, controls operation of the bridge. In particular, it operates the bridge in one of at least four modes, an idle mode, a bridging voice only mode, a bridging voice and data mode, and a bridging data only mode.

10. In a communication bridging device, a method for bridging communications between a first communication endpoint equipped with an Integrated Services Digital Network (ISDN) compliance data circuit terminating equipment (DCE) and a second communication endpoint equipped with a simultaneously voice and data (SVD) enabled DCE, the method comprising the steps of:
-
a) placing the bridging device in a first operating mode under which neither voice nor data are bridged between an ISDN end and a SVD end of the bridging device; b) placing the bridging device in a second operating mode from the first operating mode, responsive to either an ISDN voice call from the first communication endpoint or a call from the second communication endpoint while the bridging device is in the first operating mode, wherein under the second operating mode only voice is bridged between the ISDN end and the SVD end of the bridging device; and c) returning the bridging device to the first operating mode from the second operating mode responsive to either termination of an ISDN voice call with the first communication endpoint or termination of the call with the second communication endpoint while the bridging device is operating in the second operating mode. - View Dependent Claims (11, 12)
