Diversified DSL technologies and solutions

Given the massive investment in DSL broadband access services, it has become a matter of widespread concern for carriers to use existing resources to optimize the current network, reduce O & M costs, and provide richer services. As a world leading information technology manufacturer, Siemens has been committed to the Construction of China Telecom Networks for a long time. Apart from leading ADSLoverISDN/POTS solutions, Siemens has the latest insights on xDSL access technology and overall network solutions.

Wide and narrow band "integrated" solutions-currently, backbone networks of PSTN, ATM, and IP have been formed. At the access layer, integrated access can avoid repeated construction and save equipment investment. The integrated access method mainly enables operators to make full use of copper network resources, quickly deploy wide and narrow band users, and facilitate unified management of equipment and services by operators; as a partner of Siemens's largest voice and data network products overseas, BISC's "integrated" Integrated Access solution provides a narrowband and broadband integrated solution, add MiniDSLAM, a small-capacity broadband access device, to RSDLU for comprehensive access to POTS, ISDN, ADSLoverPOTS, ADSLoverISDN, SHDSL, DDN, and other wide and Narrow Band Services; make full use of the original idle transmission, power supply, distribution frames, cabinets and other resources to make the original equipment have higher availability and reduce construction costs. This solution is available for various cabinets, suitable for a variety of complex use environments. Strict internal commissioning and simple one-step installation ensures rapid system deployment.

SHDSL technology-in the face of different network needs of users, the segmentation of broadband access market businesses is increasingly concerned by the industry. Currently, carriers provide asymmetric ADSL solutions for both commercial and residential users, but the demand for commercial and residential broadband is different, the transmission environment required for commercial use is a two-way and symmetric traffic environment. Its primary concern is the stability of network performance. Another 2 m leased line solution is difficult for many users because of its expensive price. With the maturity of DSL technology, especially the large-scale application of ADSL, SHDSL technology targeting commercial users will become a new choice for such users. As the successor of HDSL and SDSL technologies, SHDSL uses two/four lines to transmit symmetric 2.3 Mbit/s/4.6 Mbit/s speeds, and the transmission distance can reach 5km ~ 7 km.

Intelligent Network Management System-with the widespread development of DSL services, efficient network management systems have become the key to the continuous development of operators. The ACI network management system launched by Siemens adopts the most advanced hierarchical structure design concept and divides the system into service layer, network layer, and network element layer. The multi-SERVER Client-Server architecture and modular software system enable the system to be deployed across regions and easily implement remote management.
