A broadband integrated access scheme based on SDH

The broadband access technology in Access network presents a new development trend. The traditional telephone network is bound to transition to the next generation Telecom network with data service as the center, broadband and IP as feature. The telecom business has gradually shifted from narrow-band service such as telephone to multimedia broadband service, which integrates voice, high-speed data and variable video. Faced with many access technology, how to choose the ideal solution, efficient and economic construction to meet the needs of various users of the access network is a focus of attention.
Days Connaught Thailand based on the telecommunications operators and their users to provide broadband access to the overall solution and technical advisory services, that access equipment should be able to flexible network, narrowband, broadband services can be integrated access, and to support future development. AXX155/E is just such a product. It combines circuit exchange and packet exchange organically, in a link with IP and TDM two kinds of data flow, the formation of SDH frames, making network access very easy and simple, IP channel bandwidth can be configured to achieve 100mbit/s, to achieve real wire speed. AXX155/E is fully compatible with other IP and TDM devices, and all interfaces are designed to be based on open standards that are tailored to the needs of the user for broadband and multiple services.
AXX155/E Access system based on SDH, the advantages of SDH technology into the Access network field, the transmission of the admission scheme is in line with the SDH system standards, its speed, frame structure, function and STM-1 consistent, can be connected with the STM-1 of any manufacturer.
Access network is a rapid development of the field, can be used to access the technology in the continuous emergence, it is difficult to predict what will be the new access business, especially broadband services. AXX155/E can dynamically allocate bandwidth, will be able to adapt to the development of broadband services, its access system uses virtual container (VC) to map TDM and IP signals to the STM-1. cascaded VC can map a larger data flow than a single VC, so it can use bandwidth more efficiently and realize the demand for bandwidth. For most of the non-telecom standard broadband services, such as IP services, can improve bandwidth utilization. axx155/e IP data is mapped to the VC12 container, the bandwidth control can be controlled by the number of different quantities of VC12 (1~50) to control, IP bandwidth can reach the maximum 100mbit/s, is the real line speed, high-bandwidth equipment.
