Abstract: A method for directly converting packet-based voice data of two non-compatible formats, (e.g., VoIP and VOATM), is described. A VoIP call agent sets a connection between a VoIP edge gateway and an interworking unit (IWU). The IWU allows the VoATM network to appear as a TDM network to the VoIP call agent. The VoIP call agent selects a virtual trunk group and channel identification code through the interworking unit and transmits the selection to a VoATM call agent. The IWU allows the VoIP network to appear as a TDM network to the VoATM call agent such that the VoATM call agent establishes a connection between the virtual trunk group and a VoATM network device. The IWU allows the VoATM network to appear as a TDM network to the VoIP call agent such that the VoIP call agent establishes a connection between the virtual trunk group and a VoIP network device.

Abstract: A silicon carbide semiconductor device that includes J-FETs has a drift layer of epitaxially grown silicon carbide having a lower impurity concentration level than a substrate on which the drift layer is formed. Trenches are formed in the surface of the drift layer, and first gate areas are formed on inner walls of the trenches. Second gate areas are formed in isolation from the first gate areas. A source area is formed on channel areas, which are located between the first and second gate areas in the drift layer. A method of manufacturing the device ensures uniform channel layer quality, which allows the device to have a normally-off characteristic, small size, and a low likelihood of defects.

Abstract: Methods and apparatus are disclosed for changing the bandwidth or other traffic characteristic of an established packet call in response to an identification of the requirements of the call. For example, in response to the detection of a type of call, such as a fax or modem call, ATM signaling is performed with peer signaling agent(s) located in the ATM network to increase the bandwidth of an already established portion of a call through the ATM network. This signaling typically includes sending a call modify request message and receiving a modify acknowledgement message, with these messages typically, but not limited to, conforming with a Q.2963 signaling standard.
