advantages, and each has its own shortcomings.1 Current main access network technologyIn many scenarios, ADSL technology using the original telephone lines, without modification can transmit high-speed data (downlink 12.5-8mb/s, uplink 16-640kb/s), the local Dslam after reuse and ATM network adaptation, is a traditional carrier development network special fancy of the program, But ADSL provides the bandwidth is not too high, the actual use of the ope

First look at a picture, the painting is very frustrated, will see.When the TCP client communicates with the server, it is the server that gets the client's socket to communicate.TCP is equivalent to a previous landline, has an earpiece and a microphone, a speaks with a microphone, and B listens with the earpiece.Let's talk about the use of TCP in Java and the steps.TCP Client steps:1. Set up the socket service and identify the IP and port2. Get the i

can I use the API? Is there any other way to do this ?? Nokia introduced the use of ASP voice proxy server, which is a plug-in. In this case, the program will be very large. How can this intercom be implemented ?? Answer: You can capture and play simultaneously on s60. Refer to this example File Name: S60_Platform_Full-Duplex_Audio_Example_2_0_en.zip Description: This C ++ example application plays and records audio simultaneously, reading from the microphone and writ

class, listening for and accepting connections to this socket.2. The client program creates a socket and requests a connection to the server.3, the server receives a connection request from the client, the Accept () method returns a socket object and obtains the data from the client.When using the Accept () method of the service-side ServerSocket If the data is heard, the socket object returned is the client with the requested connection.Socket, where the OutputStream object obtained by the ser

China's communication industry is developing rapidly, with more and more market demands. At the same time, many Internet access technologies and methods have emerged, here we will introduce you to the discussion about data bypass in the access technology. Currently, Internet access is divided into two types: broadband access and narrowband dial-up access. For broadband access, there are two main methods: ADSL access based on existing copper access networks and direct data access based on optical

Many enterprise users usually deploy VOIP network phones as one of the most important considerations when deploying network applications. In terms of enterprise-level mature network application models, the trend of such VOIP phones becoming the mainstream communication applications of enterprises is becoming more and more obvious. In fact, according to a recent survey by Telappliant, 100 of the 41% companies in various UK industries are already using VoIP phones, in order to improve the efficien

Suppose you call a little (local host), live in a large yard (local area network), there are many neighbors (Internet neighbors), the door of the front of the door to see the big Uncle Li, Li is your gateway. When you want to play with a partner in the yard, as long as you shout his name in the yard (ping him), he will respond to you when he hears it and run out to play with you.But you are not allowed to walk out of the door, you and the outside world all contact, must master Li (Gateway) to he

The past wiring method is to the various facilities of the wiring design and construction, such as telephone systems, fire, security alarm systems are independent. A high degree of automation in the building, a variety of line including, not only difficult to manage, cabling high cost, and lack of function, not adapt to the needs of the situation. Integrated wiring is to take these shortcomings and adopt standardized measures to achieve a unified mate

1 frameworks/base/telephony/Java/Android/telephony/CDMA provides APIs for using the specific telephone functions of CDMA.1.1) cdmacelllocation is the direct derived class of celllocation, indicating the location of a CDMA mobile phone call.Code Division Multiple Access, also known as code division multiple access, is a technology used in wireless communication. CDMA allows all users to use all the frequencies at the same time (1.2288 MHz ), in additio

waiting for the CPU to process over a period of time, that is, the length of the CPU usage queue. It is also simple to say that the length of the process queue, load average data is to check the number of active processes every 5 seconds, and then calculate the value by the specific algorithm.There are two different concepts to differentiate between CPU load and CPU utilization. CPU utilization shows the percentage of CPU that the program consumes in real time during runtime, while the CPU load

information on stress testing, an analogy to explain the difference between CPU utilization and load average and the implications for stress testing? We'll analogy the CPU to a phone booth, and each process is a person who needs to call. There are now 4 telephone booths (just like our machines have 4 cores) and 10 people need to call. The rule for using the phone now is that the administrator will give each person a 1-minute use of the phone in the o

network broadband access, high-speed Internet access, the user access to multimedia information greatly increased, to achieve high-speed Internet access and save costs; In addition to the traditional Internet Service (send and receive email, FTP, www browsing, online chatting, playing games, etc., but also can carry out value-added services such as VOD video-on-demand business, narrow band with multimedia information Services (online education and training, online medical, IP video conferencing

Field As IP phones enter the market, IP Phone operators will launch new applications in addition to providing voice mail, call waiting, and high-speed access services to make their services favored by users. 1.1 assign the IP address of a common phone A new application of IP phones is to assign IP capabilities to common phones. For example, Aplio/Phone2.0, recently released by Aplio, can connect common telephones to the Internet and be used together with IP phones and conference software compat

What is ip pbx? Ip pbx is a complete set of technologies that can provide telephone calls through the IP data network. All sessions are transmitted over the network in the form of data. This technology not only includes advanced communication functions, but also provides enterprises with extensibility and reliability. Ip pbx can also be connected to a traditional PSTN line through an optional gateway. Therefore, it is easy to upgrade daily business co
