The MLLN, Managed Leased Line Network is an integrated, fully managed, multi-service digital network platform through which BSNL can offer a wide range of services at an optimal cost to Business Subscribers. Backed by a flexible Network Management System with powerful diagnostics and maintenance tools, the MLLN can be used to provide high-speed leased lines with improved Quality of Service, High availability and reliability.
The MLLN provides variable bandwidth line connectivity. The State-of-the art technology equipment MLLN is designed mainly for effective control on the leased lines so that the down time is very much minimized and the circuit efficiency is increased thus achieving more customer satisfaction. This supports data ranging from 64 Kbps to 2048 Kbps. In MLLN Network conventional PCM Primary Mux and subscriber Modems are replaced by Versatile Mux and Network Terminating Units respectively. MLLN mainly consists of Digital Cross Connect (DXC), Versatile Mux (V-Mux), Network Terminating Unit (NTU) and Network Management System (NMS). DXCs and V-Muxs are interconnected via optical fibre links and alternate routing facility incase of any route failure. V-Mux is in turn connected to NTUs at Customer premises through 2 wire copper pair. At the top of it NMS is suitably placed in a central location for effective control and monitor. NTUs are fully managed from NMS.They are programmable for different data speeds ranging from 64kbps to 2048kbps.
• Controlled and Managed Leased Line Network • Bandwidth management as per the Customer demand. • Pro-active maintenance, without waiting for customer to book a complaint. • Self diagnostic/software loops to check E1 connectivity to DXC,V-Mux /software loop checking copper pair at NTU point for immediately identifying the fault section for troubleshooting. • Alternate routing in case of any route failure. • Generation of the periodic performance reports for self-analysis.
• Bandwidth management as per customer requirement (64 Kbps and Nx64 Kbps upto 2048kbps) • Saving the cost of modems. NTU is provided by BSNL without any charge. • Time dependent Bandwidth
Leased circuits on MLLN can be provided in the places being served under the following Telephone Exchange Areas in Calcutta Telephones.
Due to the wide range of applications in various sectors like Banking, Financial Institutions, Stock Markets, Newspaper Industry, Broadcasting Houses and Internet Service Providers, this Managed Leased Line equipment will benefit all sections of people be way of faster Internet access, Accessibility of Bank Accounts from anywhere, instant news coverage etc.
