Abstract: A fax-aware telephone for handling facsimile transmissions over a computer network, such as the Internet, that includes a facsimile processing unit for handling an incoming or outgoing facsimile call, a voice processing unit for handling an incoming or outgoing voice call, a memory unit for storing an incoming facsimile transmission, and a file transfer protocol client for transferring a facsimile transmission to the computer network, an external storage device, or to a printer driver. The fax-aware telephone handles a facsimile call and a voice call together over a single data line from a computer network.

Abstract: A method to reduce memory requirements for a packet loss concealment algorithm in the event of packet loss in a receiver of pulse code modulated voice signals. A voice playout unit in the receiver shares its nominal delay buffer with a history buffer of a packet loss concealment algorithm up to a maximum limit described in a standard. This reduces or eliminates need to allocate memory for the history buffer. A history buffer can also be extended to retain an original portion of voice signal packets received prior to a packet loss as well as generated voice signals as they are generated. A scratch buffer is used as a working buffer and replaces the function of a pitch buffer.

Abstract translation: 在脉冲编码调制语音信号的接收机中发生分组丢失的情况下，减少分组丢失隐藏算法的存储器要求的方法。 接收机中的语音播出单元使用分组丢失隐藏算法的历史缓冲器共享其标称延迟缓冲器，直到标准中描述的最大限度。 这减少或消除了为历史缓冲区分配内存的需要。 还可以扩展历史缓冲器以保留在分组丢失之前接收到的语音信号分组的原始部分以及在生成的语音信号时产生的语音信号。 暂存缓冲区用作工作缓冲区，并替代音调缓冲区的功能。
