    Abstract: Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, mechanisms, and means for establishing a call across a network. For example, the network may include a first edge switch, a second edge switch, and an ATM core network coupled to the first and the second edge switches and configured to allow the second edge switch to communicate with the first edge switch. The second edge switch, being responsive to a received Q.2630.1 AAL2 message, is configured to send a first Private Network-Network Interface (PNNI) setup message to the first edge switch as part of establishing a call between or through one or more of the first and the second edge switches.

    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. 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.

    Abstract: In general, in one aspect, the disclosure describes a semiconductor device that includes a functional circuit and a dc-to-dc power converter. The power converter converts, regulates, and filters a DC input voltage to produce a DC output voltage and provides the DC output voltage to the functional circuit. The dc-to-dc power converter has an operating frequency above 10 MHz.

    Abstract: An embodiment may include an apparatus comprising a dejitter buffer to receive packets containing audio data, a codec coupled with the dejitter buffer, the codec to receive coded audio frames from the dejitter buffer and decode them, and a concealed seconds meter coupled with the dejitter buffer, the concealed seconds meter to record concealment events by the decoder to provide an objective measure of media impairment. Another exemplary embodiment may be a method comprising receiving packets containing audio information at a dejitter buffer, decomposing the packets to coded audio frames, sending the coded audio frames to a decoder and decoding the frames, generating a concealment output stream if the decoder does not receive a valid frame from the dejitter buffer, and recording concealment events to provide an objective measure of media impairment.
