There are still many access networks in the video conference. Here we will introduce common access methods in section 7, including using ISDN lines, renting ddnleased lines, and using PSTN systems. Most users are most concerned about Video Conferencing Systems in the following aspects: audio and video quality, system price, system security, and scalability. There are two common network environments: one is a circuit switching network, such as
interface between GSM system and other public telecommunication networkOther public telecommunication networks mainly refer to public telephone networks (PSTN), Integrated Services Digital Networks (ISDN), packet-switched public data networks (PSPDN) and circuit-switched public data networks (CSPDN). GSM systems are interconnected with these public telecommunication networks through MSC, and their interfaces must meet CCITT's relevant interfaces and

For most users, the most important factors of video conferencing system are the following aspects: Audio and video quality, system price, security and scalability of the system. At present, there are two main types of network environment, one is based on circuit switching network, such as ISDN, DDN, PSTN and so on. The other is a packet-switched network, such as ATM, IP, Frame Relay, and so on.

entirely on the state of the function called, similar to the closure structure, this will point to the window Global Object. Through the call, you can specify the this value in the call function.
JS classes are generally written into closures, and prototype is used for objects. Prototype and function objects are the most special of JavaScript (I personally think the coolest part, the key is that the writing is very flexible and the reading structure is very clear ), so I generally like to use
