Network Telephony Application of network developmentFirst, the original telephone communication introductionWe are familiar with the telephone communication methods, generally there are two kinds. One is a wired landline, the other is a wireless mobile phone (where I see wireless landline phones as a landline). Although the two kinds of telephone communication in

I. Overview Integrated wiring is a modular and highly flexible information transmission channel between buildings or architectural complexes. It enables voice, data, imaging, and switching devices to connect with other information management systems, as well as external connections. It also includes all cables and related connection parts between the connection point of the building's external network or the telecommunication line and the application system equipment. Integrated wiring consists

communication with the outside world, and increase investment. 　　And with the development of business and the size of the increase in communications costs will increase the trend of increase in telecommunications costs in this middle occupies a large proportion. So how can companies reduce these costs and improve competitiveness? 　　In addition to the management of ways to save costs, the advent of VoIP technology for enterprises from the technical level to reduce communication costs to provide

Implementation principles and key technologies of VOIP: basic principles and implementation forms IP telephone systems convert analog signals of common telephones into IP data packets sent by computers over the Internet, at the same time, it also converts the received IP packet into a sound analog electrical signal. After the conversion and compression of the IP Phone System, the transmission rate of each common phone is approximately 8-11 kbit/s band

The strong electric well is 36 volts above can make people's doom of the Wire, is generally 220 volts of the mains power cord, weak in the well is 36 volts below the electricity of the dead wire, such as

Local network, the English name is network. The local network is the abbreviation for the local telephone network, which is a telephone network consisting of a number of end bureaux or a plurality of end bureaux and sinks, a repeater, a long city relay, a subscriber line and a telephone terminal within the same long-distance numbering area.Each local network is

I. Introduction When a call is established for a traditional telephone exchange network, the signaling point code of the next exchange board is determined based on the E.164 number of the called phone number, and then the call is routed through the No. 7 signaling network according to the signaling point code, the essence of all call routes is to determine the signaling point encoding according to E.164, and then use the signaling point encoding for

This question is simple at the beginning. It is nothing more than converting a string of characters into a phone number separated, then, output the number that appears more than once in alphabetical ascending order. However, this operation will time out... in fact, the '-' in the middle of the phone number is removed, and the phone number is actually an integer. With this idea, it's easy. You only need to set up an extremely large array containing all possible phone numbers, and the value of the

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
