摘要： A jitter buffer controller allows the depth of the jitter buffer to be adjusted dynamically according to the varying jitter of the current sequence. The contents of the jitter buffer are examined during a transmission. If the delay or average delay within the buffer drops to a predetermined threshold, then the size or depth of the jitter buffer is increased.

摘要： A method of transmitting DTMF signals over a compressed computer network (24) comprises sending a packet containing a compressed DTMF signal followed by a confirmation packet. The confirmation packet preferably comprises an uncompressed DTMF signal which is transmitted on the same logical channel as the packets that represent voice signals. To detect the DTMF signal transmitted, a telephony Internet server (28) decompresses packets as they are received. If a packet appears to contain a compressed DTMF signal, the telephony Internet server looks for the presence of the confirmation packet before processing the previously received packet as a DTMF signal. In an alternative embodiment, the confirmation packet comprises a code that represents a DTMF signal. The packets that represent the voice signal and the code representing the DTMF signal are sent on separate virtual channels of the same logical channel. At a receiving end, data on one channel is directed by a separation logic block (114) to a speech decompressor (116) while another channel is directed to a DTMF signal generator (118) that generates a DTMF signal when a corresponding code is detected. The outputs of either the speech decompressor or the DTMF signal generator are applied to a receiving telephone (124).
摘要翻译：一种通过压缩计算机网络（24）发送DTMF信号的方法包括发送包含压缩DTMF信号的数据包，随后是确认数据包。确认分组优选地包括在与表示语音信号的分组相同的逻辑信道上发送的未压缩DTMF信号。为了检测所发送的DTMF信号，电话互联网服务器（28）在收到分组时解压缩数据包。如果分组看起来包含压缩的DTMF信号，则电话互联网服务器在将先前接收到的分组处理为DTMF信号之前查找确认分组的存在。在替代实施例中，确认分组包括表示DTMF信号的代码。表示语音信号的分组和表示DTMF信号的代码在相同逻辑信道的分开的虚拟信道上发送。在接收端，一个信道上的数据被分离逻辑块（114）引导到语音解压缩器（116），而另一个信道被引导到当检测到相应代码时产生DTMF信号的DTMF信号发生器（118）。语音解压缩器或DTMF信号发生器的输出被应用于接收电话（124）。

摘要： A system and a method for managing incoming calls within a call queue include a network bandwidth monitor for monitoring network bandwidth availability on a call center and a queue call rate monitor for determining a total of all call charge rates associated with the calls. A queue manager determines the order of advancement of the calls within the queue. If the network bandwidth monitor determines that network bandwidth availability is below a predetermined threshold, high network bandwidth calls are preferentially advanced to free up additional network bandwidth. Calls with high charge rates are preferentially advanced if the total call charge rate in the queue exceeds a predetermined maximum threshold. If the maximum total call charge rate threshold is exceeded and the network bandwidth availability level is below the minimum threshold, a relative priority for maintaining network bandwidth availability and reducing total call charge rates will determine the order of call advancement. In a preferred embodiment, a router resource monitor determines whether router resource availability is above a minimum threshold level. Different priority sets are configured for each combination of a low network bandwidth availability state, a low router resource availability state, and/or a high total call charge rate state. Call advancement within the queue is at least partially determined by the priority sets.

摘要： A method and system for providing security for a computing device include resolving conflicts between a password-protected screen saver and communication notification capabilities by selectively enabling access to specific communications when the computing device is in a locked mode. The screen saver of the computing device is configured to switch the device from a normal operative mode to a locked mode in response to detection of a preset condition, such as the expiration of an idle-time timer. The computing device then remains in the locked mode until a preset authorization condition is recognized, e.g., entering a password. However, with the computing device in the locked mode, a subset of communication access capabilities is enabled. Specifically, notification of incoming communications is enabled. Preferably, connectivity for select types of outgoing calls is also enabled, e.g., connectivity for emergency calls. In the preferred embodiment, the conflicts are resolved by integrating the screen saver with communication access capabilities in a single software package. Also in the preferred embodiment, the communication access capabilities are provided by a telephony over LAN application and a switch to the locked mode is disabled during communication sessions involving the computing device. In other embodiments, while in a locked mode, incoming calls may be preconfigured by the user to selectively break through security features based on caller identification information.

摘要： Methods and apparatus are described for facilitating multiple data communications with a first platform (100, 102, and 104) using a single communication conduit (108) having first and second channels. First data are transmitted between the first platform and a second platform (114) via the first and second channels (202). It is determined whether an incoming call comprises second data of a particular type (206). Where the incoming call comprises the second data of the particular type (208), transmission of the first data via the second channel is inhibited (226) thereby enabling reception of the second data by the first platform via the second channel while the first data continue to be transmitted via the first channel. The second data are then received at the first platform via the second channel (230). Transmission of the first data via the first and second channels is resumed in response to termination of transmission of the second data (266).

摘要： An embodiment of the present invention provides an audio message, such as the identification of a caller, without requiring pre-recording by the call receiver, and providing the audio message in the caller's own voice, if they so desire. According to an embodiment of the present invention, a caller may record her identification prior to making a telephone call. The recorded identification would be sent along with each call the caller makes. The caller's recorded identification would be received by the receiver and announced to the receiver. The caller may also record an image to be sent along with her calls such that the receiver of her call may see her recorded image displayed when her call is being announced. Accordingly, an embodiment of the present invention allows identification of first-time callers and infrequent callers without the need for the call receiver to pre-record the caller's identity.

摘要： A contention protocol permitting transmission of isochronous data. A device (104) wishing to transmit isochronous data can reserve periodic time slots for the transmission. Either the device (104) or a network controller (101) transmits the reservation information to other devices (106, 108) on the network. When non-isochronous transmissions are desired, the devices (104, 106, 108) contend for access using the CSMA/CD protocols, but taking into account the already reserved time slots. For example, the reserved period may be added to the randomly chosen backoff window. Alternatively, if a backoff window expires during a reserved period, the backoff window may be restarted upon completion of the reserved period. If not all the devices (104, 106, 108) on the network employ this modified CSMA/CD protocol, a "dummy" frame is provided at the beginning of each isochronous transmission. If another device is contending for access, the dummy frame collides, and the other device backs off. The isochronous transmission then proceeds.

摘要： A safety system for electronic devices having multiple power inputs includes dedicating a different power detector to each power input and includes disabling all of the power inputs upon detection that one input has been disabled. Each of the power inputs is typically a power cord that provides electrical energy to a discrete electrical circuit. Thus, the safety system permits the electronic device to use a different power supply for each electrical circuit, while ensuring that there is no erroneous assumption that disconnecting one of the power cords will de-energize the entire electronic device. In the preferred embodiment, the paths to the power supplies are disabled by opening relay switches, with the switches that are specific to a power cord being in a logical AND arrangement.
