摘要： A system, apparatus, and method for fault-tolerant communication of data embodied in a packet. The communication includes transmission of a starting sequence signal, the starting sequence signal including a first character string followed by a second character string. Transmitting the packet of information after the starting sequence signal has been transmitted, and transmitting an ending sequence signal after the packet has been transmitted, the ending sequence signal including a third character string followed by a fourth character string. The present invention also includes receiving the starting sequence signal transmitted from the transmitting means, and comparing the first and second character strings for the starting sequence signal to first and second pre-determined character strings. A buffer is reset so that it may receive the packet if the first and second character strings match the first and second pre-determined character strings, respectively. Once the buffer is reset, the ending sequence signal is received and the third and fourth character strings of the ending sequence signal are compared to third and fourth pre-determined character strings. If the third and fourth character strings match the third and fourth pre-determined character strings, respectively, the received packet is processed. If the third and fourth character strings do not match the third and fourth pre-determined character strings, the packet is disregarded.
摘要翻译：用于容纳在分组中的数据的容错通信的系统，装置和方法。通信包括发送起始序列信号，起始序列信号包括第一字符串和第二字符串。在发送起始顺序信号之后发送信息分组，并且在分组被发送之后发送结束序列信号，结束序列信号包括第三个字符串，随后是第四个字符串。本发明还包括接收从发送装置发送的起始序列信号，以及将起始序列信号的第一和第二字符串与第一和第二预定字符串进行比较。缓冲器被复位，使得如果第一和第二字符串分别与第一和第二预定字符串匹配，则可以接收数据包。一旦缓冲器复位，接收到结束序列信号，并将结束序列信号的第三和第四字符串与第三和第四预定字符串进行比较。如果第三和第四字符串分别与第三和第四预定字符串匹配，则处理接收到的分组。如果第三和第四字符串与第三和第四预定字符串不匹配，则忽略分组。

摘要： The present invention includes software and hardware components to enable digital data communication over standard telephone lines. The present invention converts analog voice signals to digital data, compresses that data and places the compressed speech data into packets for transfer over the telephone lines to a remote site. A voice control digital signal processor (DSP) operates to use one of a plurality of speech compression algorithms which produce a scaleable amount of compression. The rate of compression is inversely proportional to the quality of the speech the compression algorithm is able to reproduce. The higher the compression, the lower the reproduction quality. The selection of the rate of compression is dependant on such factors as the speed or data bandwidth on the communications connection between the two sites, the data demand between the sites and amount of silence detected in the speech signal. The voice compression rate is dynamically changed as the aforementioned factors change. A negotiation handshake protocol is described which enables the two sites to negotiate the compression rate based on such factors.

摘要： A personal communications system is described which includes components of software and hardware operating in conjunction with a personal computer. The user interface control software operates on a personal computer, preferably within the Microsoft Windows.RTM. environment. The software control system communicates with hardware components linked to the software through the personal computer serial communications port. The hardware components include telephone communication equipment, digital signal processors, and hardware to enable voice, fax and data communication with a remote site connected through a standard telephone line. The functions of the hardware components are controlled by control software operating within the hardware component and from the software components operating within the personal computer. The major functions of the system are a telephone function, a voice mail function, a fax manager function, a multi-media mail function, a show and tell function, a terminal function and an address book function. The telephone function allows the present system to operate, from the users perspective, as a conventional telephone using either hands-free, headset or handset operation. The telephone function is more sophisticated than a standard telephone in that the present system converts the voice into a digital signal which can be processed with echo cancellation, compressed, stored as digital data for later retrieval and transmitted as digital voice data concurrent with the transfer of digital information data.

摘要： A personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. The personal communications system is equipped with two telephone line interfaces to allow connection between two remote sites. The connection between the first remote site and the local site may operate in a voice over data communications mode to simultaneously send compressed voice and data. A digital transmission protocol which is consistent with current packet standards is used to create an independent channel through use of a modified supervisory packet for negotiating communication parameters, including the speech compression algorithm, the speech compression ratio, the communication multiplex scheme, and other operations needed for control of remote hardware interfaces.

摘要： Outgoing multi-media data components are provided in a communication system and method implemented under control of a user interface program. Each of the outgoing multi-media data components includes one or more types of information (e.g., textual information, graphical information, and audio information). Two or more outgoing multi-media data components are combined under control of a local user via input to the user interface program resulting in combined outgoing multi-media mail. At least one of the two or more outgoing multi-media data components is of a type of information different than another of the two or more outgoing multi-media data components. The combined outgoing multi-media mail is provided for communication to a remote location.

摘要： An interface for modems is described which provides rapid identification of a caller and limited access based on a variety of parameters obtained from caller identification information encoded by the telephone company. A line reversal detector is incorporated to signal when the caller identification information is available for reception. A two stage detection system is used to eliminate false signaling of line reversals and discriminate line reversals from ringing and other noise signals.

摘要： A personal communications system is described which includes components of software and hardware operating in conjunction with a personal computer. The user interface control software operates on a personal computer, preferably within the Microsoft Windows.RTM. environment. The software control system communicates with hardware components linked to the software through the personal computer serial communications port. The hardware components include telephone communication equipment, digital signal processors, and hardware to enable voice, fax and data communication with a remote site connected through a standard telephone line. The functions of the hardware components are controlled by control software operating within the hardware component and from the software components operating within the personal computer. The major functions of the system are a telephone function, a voice mail function, a fax manager function, a multi-media mail function, a show and tell function, a terminal function and an address book function. The telephone function allows the present system to operate, from the users perspective, as a conventional telephone using either hands-free, headset or handset operation. The telephone function is more sophisticated than a standard telephone in that the present system converts the voice into a digital signal which can be processed with echo cancellation, compressed, stored as digital data for later retrieval and transmitted as digital voice data concurrent with the transfer of digital information data.
摘要翻译：描述了个人通信系统，其包括与个人计算机一起操作的软件和硬件的组件。用户界面控制软件在个人计算机上运行，最好在Microsoft Windows TM环境中运行。软件控制系统通过个人计算机串行通信端口与链接到软件的硬件组件进行通信。硬件组件包括电话通信设备，数字信号处理器和硬件，以便通过标准电话线连接的远程站点进行语音，传真和数据通信。硬件组件的功能由在硬件组件内运行的控制软件和在个人计算机内运行的软件组件控制。系统的主要功能是电话功能，语音信箱功能，传真管理功能，多媒体邮件功能，演示功能，终端功能和通讯录功能。电话功能允许本系统从用户的角度来操作，使用免提，耳机或手机操作的常规电话。电话功能比标准电话更复杂，因为本系统将语音转换为数字信号，该数字信号可以用回波消除，压缩，存储为数字数据进行处理，以供以后检索并作为数字语音数据传输，同时传输数字信息数据。
