c#做的端口转发工具,modbus传感器数据通过外网连接服务器的502端口，但是传感器又是的modbus从站，所以开发了这款转发工具，和一般的端口转发有区别，这里实现的是502-503端口的数据互转，502是tcpserver，503也是TCPserver，tcp client<-->tcpserver(502)<-->tcpserver(503)<--->tcpclient
The data of Modbus sensor is connected to the 502 port of the server through the external network, but the sensor is a MODBUS slave station. Therefore, this forwarding tool is developed, which is different from the general port forwarding. Here, 502 is tcpserver, 503 is tcpserver, TCP client < -- > tcpserver (502) < --- > tcpserver (503) < --- > tcpcclient (2020-08-21, C#, 214KB, 下载11次)

ITU-T G.722.2
国际电信联盟G.722.2建议书，2003年7月版。该建议书是语音通讯领域的压缩标准，被GSM，WCDMA，3GPP等采用，题目为16kbit下的宽带语音编码，使用自适应多率宽带编码。
内容主要有代数码激励线性预测编码(ACELP)，话音活动检测(VAD)等。
This Recommendation describes the high quality Adaptive Multi-Rate Wideband (AMR-WB)
encoder and decoder that is primarily intended for 7 kHz bandwidth speech signals. AMR-WB
operates at a multitude of bit rates ranging from 6.6 kbit/s to 23.85 kbit/s. The bit rate may be
changed at any 20-ms frame boundary.
Annex C includes an integrated C source code software package which contains the implementation
of the G.722.2 encoder and decoder and its Annexes A and B and Appendix I. A set of digital test
vectors for developers is provided in Annex D. These test vectors are a verification tool providing an
indication of success in implementing this codec.
G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP
specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector. (2010-04-21, C/C++, 711KB, 下载117次)
