Impact scope: no device test is available for users with MX and operators, haha MX60 introduction Figure 1 Brief Description: MX60 is a carrier-level Voice Gateway. The permission settings for managing users are divided into two levels: Administrator and operator. The specific permission is granted to me (figure 2 ). However, the permiss

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

Introduction My company wowould like to set up a call center. the call center needs a VOIP router. we choosed Cisco 2811, and we applied an E1 cable to host 30 phones in. we need to do necessary configuration in the Cisco 2811 router. Config the Cisco 2811 router We have Ed the router. we started to config the router. first we checked the delivery list file in the package, and found a console cable. the console cable is used to config the router. one

It has a Chinese operation interface and is easy to set up. It is suitable for enterprises to build a telephone network and allow free calls between extensions,Each extension can also be called to a traditional telephone network, or used as a telephone customer service

Java EE Development of various types of resources download list, the history of the most complete IT resources, personal collection summary. synchronous, asynchronous, blocking, and non-blocking are some basic sockets calling methods, and one of the basic concepts that need to be understood and differentiated when doing network programming. There are a wealth of articles and discussions on this topic, whi

This article will introduce you to an article on the concepts of PHP-Socket-blocking and non-blocking, synchronization and Asynchronization. I hope this article will help you. This article will introduce you to an article on the concepts of PHP-Socket-blocking and non-blocking, synchronization and Asynchronization. I h

Blocking functions: Connect, Accept,send/recv/sendto/recvfrom and other read-write functions.Functions that do not block: Bind, Listen,socket, closesocket.The Linux network communication model is:Blocking IO Model (synchronous), non-blocking IO model (copy synchronization), IO multiplexing model (multithreaded synchronization), signal driven IO model (copy synchronization), Asynchronous IO Model (async).nod

High-performance IO Design Mode: blocking/non-blocking, synchronous/asynchronous parsing, io Design Mode When it comes to high performance, I think everyone like this. Today we will mainly understand several key concepts in high performance I/O design, the most important first step in doing anything is to make the concept clear, isn't it? Here is: blocking, non-

Callable, Future blocking queue blocking stack, callablefutureSimple Applications of Callable and Future Before Java 5, the thread does not return values. It often takes a long time to "have" the returned values, and the code is not easy to write. Or simply bypass this hurdle and go another way. Now Java finally has a task that can return values (also called a thread. The Callable interface must be implem

Recently encountered some common concepts, especially the concept of network programming, such as: blocking, non-blocking, asynchronous I/O and so on, for these concepts themselves are not too clear understanding, but very vague concept, said understand it also understand, but to let oneself accurately describe the specific details of the concept, but said not so accurate, This is the reason why they have n

To put it more simply: Obstruction is not the end of the work, no return,Non-group games you do it first, I'll see if there's anything else. Tell me when it's over. Let's take the most commonly used send and recv two functions ...For example, you call the Send function to send a certain byte, in the system sent to do the work is actually just the data transfer (COPY) to the TCP/IP protocol stack output buffer, and its success does not mean that the data has been successfully sent out, if the tcp

I. Conceptual UnderstandingIn the network programming, we often see Synchronization (sync), asynchronous (async), blocking (block), non-blocking (Unblock) four ways to call: Sync: The so-called synchronization is that when a function call is made, the call does not return until the result is obtained. That is, one thing must be done, so that the next thing is done before you can do it. Async: Asynchro

Advantages and disadvantages of blocking and non-blocking Io packages in Java The cornerstone behind NiO design: the reactor model, which is used for event Multi-Channel Separation and dispatching of the architecture model. Reactor: an architecture pattern used for event Multi-Channel Separation and allocation Generally, a file or device specified by a file descriptor can work in two ways:
