connections. This protocol allows users to define their own traffic characteristics and require the network to complete services at a specific level of QoS. Physical Layer Specification ATM can run at a rate of hundreds of megabits per second or higher. In order to support such a high data rate, strict physical layer transport protocols must be developed. The most important thing in the physical layer is the synchronous digital SDH (synchronous Digi

Since the 1990s, Wavelength division multiplexing (WDM) has been deployed on a large scale in telecommunications networks, and the system's transmission capacity has increased by one times every 12-18 months. However, the control and management of optical networks remain in the traditional sense of SDH networks: The optical layer is simply a simple transport medium in the network, and its main function is to provide static high speed optical access to

future.Today's GPRS Transmission Design In the 3GPP standard design of GPRS, the Gb interface between the group control unit (PCU) and SGSN uses frame relay technology, as shown in ):In practice, this Gb interface is usually implemented using multiple physical E1 FR interfaces on BSC/PCU and SGSN.Most networks have multiple BSC/PCU sites, which converge to a small number of central sites. GPRS Support nodes are located in the central site. In these networks, the inter-board switching service co

It is said that China Netcom wants fiber optic access Optical fiber access technology is a future-oriented Broadband Network Access Technology for optical fiber to the roadside (HTTC) and optical fiber to the household (HTTH. Fiber-optic access network (OAN) is currently the most rapidly developed Access Network Technology in China Telecom. It not only focuses on effective access to narrowband services such as telephone, it can also solve the access problems of broadband services such as high-sp
