The TDR is coupled to a PBX which is configured to route telephony data to the TDR. The TDR processes the telephony data by converting it to a form that can be transmitted over the WAN. The TDR can also re-route the data back through the PBX for transmission over a PSTN. The TDR maintains the traditional telephony interface of dialing in response to a dial tone. Using the TDR, telephony users gain advantages offered by WAN data transmission including store-and-forward delivery, optimized bandwidth allocation, and secure data transmission without having to learn a new user interface. In addition, multiple call originator telephone devices can use a single TDR.Field of SearchCombined circuit switching and packet switchingSwitching network having separate elements to handle circuit switched traffic and packet switched traffic Routing packets through a circuit switching network Routing circuit switched traffic through a packet switching network Determination of communication parameters Having a signaling feature Signaling (ancillary to main information) Adaptive Transmission bandwidth conservation Assignment of variable bandwidth or time period for transmission or reception PATHFINDING OR ROUTING Using messages having an address field as header Spanning tree Passing a signal identifying the idle or busy state of a channel (e.g., token passing) Fault detection Having transmission of a digital message signal over a telephone line Having electronic mail Computer-to-computer data streaming | |
