Dedicated line refers to relying on the backbone network and broadband metropolitan area network resources in China, providing various dedicated line access methods to meet the needs of group customers to access the Internet and conduct various applications in the city interconnection network.
For example, China Mobile's current Internet dedicated lines are divided into two categories: PON access dedicated lines and PTN access dedicated lines.
Dedicated lines provide group customers with dedicated links of various speeds, directly connecting to China Mobile's CMNet network, enabling convenient and fast high-speed Internet access services. Customers can access China Mobile's Internet through wired or wireless means, with flexible bandwidth options.
In addition to providing basic high-speed Internet access functions, dedicated lines can also support various new Internet comprehensive applications, such as multimedia information retrieval, IP telephony, video conferencing, online, e-commerce, etc.
The composition of home broadband networks is similar to a highway system, with high-speed roads between cities, municipal roads within cities, branch roads, and access roads connecting to users' homes or neighborhoods. The "access line" is like the road connecting the user's doorstep or neighborhood entrance to the municipal road.
"Access speed" refers to the speed that the "access line" can achieve. Generally speaking, the higher the access speed, the shorter the waiting time for Internet access, and the better the user experience. "Bandwidth" represents the ability of communication lines to transmit data. "Bandwidth" is like the width of roads in a highway system. Increasing bandwidth is equivalent to widening the road, allowing more and faster traffic.
