Multi-DSL technology and solutions

In the face of the large-scale input of DSL broadband Access service, how to optimize the current network and reduce the cost of operation and maintenance while providing more abundant business has become a widely concerned problem for operators. As a leading global information technology manufacturer, Siemens has long been committed to the construction of China Telecom network. In addition to having a leading adsloverisdn/pots solution, Siemens has the latest insights on xDSL access technology and overall network solutions. --Editor

Wide, narrow band "integration" solution-the current PSTN, ATM, IP backbone Network has been formed, in the access layer through integrated access to avoid duplication of construction, save equipment investment. Integrated access to this "integration" approach is to enable operators to fully utilize the copper wire network resources, rapid deployment of narrow band users, while facilitating the operator of the equipment and the unified management of the business; as a partner of Siemens ' largest voice and data network products, Bisc Company's "integration" Integrated Access solution provides narrowband and broadband convergence solution, add small capacity broadband access equipment in Rsdlu Minidslam, integrated access pots, ISDN, adsloverpots, Adsloverisdn, SHDSL, DDN and other narrow band business , make full use of the original free transmission, power supply, wiring frame, cabinets and other resources, so that the original equipment has a higher availability, reduce construction costs; The solution introduces a variety of indoor (outside) boxes, suitable for a variety of complex use environment, strict internal debugging and simple "one-step" installation concept to ensure rapid deployment of the system.

SHDSL technology--facing the different needs of users to the network, the segmentation of the broadband access market is more and more concerned by the industry. At present, operators for both commercial users and residential users are asymmetric ADSL scheme, but the demand for commercial and home broadband is different, the business needs of the transport environment is a two-way, symmetrical traffic environment, the stability of network performance is its primary concern. Another 2M-line scheme is hard to bear for many users because of its expensive price. With the maturity of DSL technology, especially the large-scale application of ADSL, the SHDSL technology for commercial users will become a new choice for this kind of users. SHDSL, as a successor to HDSL and SDSL technology, uses a 2-line/4-line transmission of symmetrical 2.3mbit/s/4.6mbit/s rates, with transmission distances up to 5km~7km.

Intelligent network Management System--with the wide development of DSL business, efficient network management system has become the key to the continuous growth of operators. The ACI network Management system introduced by Siemens adopts the most advanced hierarchical structure design concept, which divides the system into service layer, network layer and network element layer. Multi-server Client-server structure, modular software system, make the system has cross-regional deployable, easy to achieve remote management.
