摘要： The present invention enables a dial modem capable of simultaneous voice and data (SVD) operation and connected to a conventional telephone set to automatically select between SVD operation, analog voice operation and digital data operation when transmitting or receiving communication signals based on the position of the telephone set's hookswitch. The invention includes a hookswitch position detector, connected to the telephone set, for sensing the current position of the hookswitch, and a signal controller, connected to the hookswitch position detector. The signal controller may be configured to enable either of two hookswitch control option settings. The hookswitch control option settings determine the manner in which the controller responds to the current hookswitch position ("on-hook" or "off-hook") detected by the hookswitch position detector. The first hookswitch control option setting causes the signal controller to disable the initiation of SVD operation by the modem when originating and receiving calls if the hookswitch position detector indicates that the hookswitch position is "off-hook." The second hookswitch control option setting causes the signal controller to enable the initiation of SVD operation by the modem when originating and receiving calls if the hookswitch position detector indicates that the hookswitch position is "off-hook."
摘要翻译：本发明使得能够同时进行语音和数据（SVD）操作并连接到常规电话机的拨号调制解调器能够在基于该信号的位置发送或接收通信信号时在SVD操作，模拟语音操作和数字数据操作之间自动选择电话机的钩开关本发明包括连接到电话机的钩开关位置检测器，用于感测钩开关的当前位置，以及连接到钩开关位置检测器的信号控制器。信号控制器可以被配置为启用两个钩开关控制选项设置中的任一个。钩开关控制选项设置决定了控制器响应钩开关位置检测器检测到的当前钩开关位置（“挂机”或“摘机”）的方式。第一个钩开关控制选项设置使得信号控制器在发起和接收呼叫时禁止由调制解调器启动SVD操作，如果钩开关位置检测器指示钩开关位置为“摘机”。第二个钩开关控制选项设置使得信号控制器在发起和接收呼叫时启用调制解调器的SVD操作，如果钩开关位置检测器指示钩开关位置为“摘机”。

摘要： A transmitting Mu-law modem creates a probe signal by modifying the 7th bit of each of a number of PCM samples during the "hand-shaking" phase of a data connection. Furthermore, the transmitting Mu-law modem only makes this modification on those PCM samples that fall into the range of segment 1 as defined in CCITT Recommendation G.711. Similarly, a receiving Mu-law modem searches for this known pattern. Upon detection of this pattern, the receiving Mu-law modem provides an acknowledgment signal and both modems subsequently switch to a digital-mode of operation. On the other hand, if, in fact, there is a least one analog link in the data connection, the probe signal becomes distorted and, since the receiving Mu-law modem does not detect the probe signal, handshaking is completed in the standard fashion.

摘要： A modified version of the operating communication program of a stored program controlled apparatus is installed with the aid of a downloadable start address specification means, optionally realized with an EEPROM memory. The start address specification means stores information that is downloaded through a communication port in the apparatus, and that information is used in defining the address from where the communication programs are initiated. In accordance with the method of this invention, downloading of the entire new set of programs is effected by first downloading a segment of the essential portion of the new package of programs. Control is then transferred to the new segment by downloading appropriate information into the start address specification means. Thereafter, utilizing the downloaded essential portion of the new package of programs, the remainder of the new package is downloaded.

摘要翻译：发送的律法调制解调器通过在数据连接的“握手”阶段期间修改多个PCM采样中的每一个的第7位来产生探测信号。此外，发送的律法调制解调器仅对落在CCITG建议G.711中定义的段1范围内的那些PCM采样进行此修改。类似地，接收的Mu律调制解调器搜索该已知模式。当检测到这种模式时，接收的律法调制解调器提供确认信号，并且两个调制解调器随后切换到数字操作模式。另一方面，如果事实上在数据连接中存在至少一个模拟链路，则探测信号变得失真，并且由于接收到的律法调制解调器没有检测到探测信号，所以以标准方式完成握手。
