Transfer from China VoIP Forum On the PBX or local switch side, a small amount of power is not fully converted and returns along the original path, forming an echo. If the caller is not far from the PBX or vswitch, the echo will return very quickly and the Speaker cannot hear it. In this case, it does not matter. However, when the response time exceeds 10 ms, the human ears can hear the echo. In order to prevent echo, echo cancellation technology is

I. Protocol | protocols The protocol is used to define the methods and attributes required to complete certain functions. The protocol itself does not provide specific implementations of these functions, but is only used to describe these implementations. Classes, structs, and enumerations use the Protocol by providing the methods and attributes required by the Protocol. The type that can meet the Protocol requirements is called the Protocol owner. The Protocol may require the owner to provide s

telephone systems, there is a so-called "circuit counterattack ". The main original ECHO is a 2-4 Line conversion in the system. The mixer that completes the 2-4 conversion results in "leakage" due to impedance matching, resulting in "circuit echo ". From the connection method of the Internet IP Phone gateway, we can see that one end of the IP Phone gateway is connected to the PSTN and the other end is connected to the Internet.Although circuit ECHO is generated in the PSTN, it is also transmit

For rookie-level users, the most afraid of is the product problem, what small problems require people, it is extremely depressed. But many times the fault is oneself can solve, the following 52 hardware forum Netizen collects and collates several common trouble-solving methods, to treat the user. Perhaps after reading you will find yourself become a speaker master. 1. Sound can be played normally, but the noise of "chip-BA-PA" will come out from now

The audience at the best listening location (sweet spots) can ideally hear all the 3D audio effects, and the sound in other areas will be distorted. In this way, we need to select the correct position when listening. For a pair of speakers, there is a balance, vocal cords, details, three-dimensional sense of the best listening position, called Sweet Spot. Recording and production are always important for listening. Sweet Spot is usually located in the middle of a pair of stereo speakers, several

Each intent is associated with each IP prefix (destination IP) and connects the ingress connection point of the SDN network with a single egress connection point, pointing to the destination IP of the next-

object can have many types of sub-objects. For example, we have an object for managing sound cards. There may be several input and output ports on a sound card. We need to allocate a subobject to each input and output plug-in. Suppose we have an input wire plug-in, a microphone input plug-in, and a speaker output port, so we can have three sub-objects: ilinein, imicin, and ispeakerout. Each single object can have a function that controls its own plug

gateway one end of the PSTN connected to the other end of the Internet. 　　 Although the circuit echoes are generated in the PSTN, they also transmit the IP telephony gateway, which is one of the echo sources in the Internet voice transmission, and the second echo source in the Internet voice transmission is the so-called "acoustic echo". Acoustic echo is the sound of the Speaker's voice is picked up by the microphone to send back to the far end, which allows the remote speakers to hear their ow

What's AspectJ is described in http://www.ibm.com/developerworks/cn/java/l-aspectJ/index.html. The ASPECTJ is a code-generation tool (Generator). The ASPECTJ syntax is the syntax used to define code generation rules. If you have used Java Compiler Compiler (JavaCC), you will find that the concept of code generation rules is strikingly similar. ASPECTJ has its own syntax compiler tool, the result of compiling is Java class file, when running, classpath need to contain aspectj of a jar file (runti

Spring instantiates Bean using the static factory Method Knowledge Point introduction:Static factory, as its name implies, is to call the static factory method to obtain the desired objects. To allow spring to manage all objects, we cannot directly use engineering. the static method () is used to obtain objects, but is still obtained through spring injection.[For more information, see http://blog.csdn.net/mahoking] Procedure:1.

. When you execute many APIs in DbContext, the run of the DetectChanges method can be caused. In most cases, the DetectChanges method is fast enough to avoid performance problems. However, if there are a large number of objects in the memory or DbContext operations are performed one after another, the self-change detection behavior will become a performance concern. Fortunately, there are options to disable the automatic change detection and manually call it as needed. However, a slight careless
