3. Leased lines Limited to point-to-point communication Limits who you can talk to Carriers offer leased lines at an attractive price per bit sent to keep high-volume customers Leased Line

4. Point to point connection. Multi-label-protocol-switching(MPLS) VPN. Internet Leased Line.

5. A dedicated link through the service providers’ network. This link is not shared with other customers, and provides a dedicated circuit between two locations it is a permanently established circuit through the service provider’s switched network, similar to what is illustrated in the figure below.

8. This connection is directly "laid in" for you - thus you end up with a dedicated connection - for high end business's usually, with higher speeds, lower contention and faster response times to any problems. Data security.

9. As the organization grows present networking solution becomes costly since we will have to invest on Multiple links and Networking equipments. Provisioning & Commissioning.

10. MPLS VPN stands for MULTIPROTOCOL LABEL SWITCHINGVIRTUAL PRIVATE NETWORK. An MPLS Network is formed by connecting each location with a single link to a service provider MPLS network

13. The performance characteristics of layer 2 networks The connectivity and network services of layer 3 networks Improves the price/performance of network layer routing Improved scalability

14. Quality of Service: Since MPLS network enables traffic engineering, it is possible to send (for example) – data traffic over a lower priority path and real time delay sensitive voice/ video packets over a high priority/ lesser used/ shorter path. This enables network convergence (The Wide Area Network becomes more suitable for introduction of new services like voice, video, multicast traffic, hosting etc). Connection oriented network: MPLS is a connection-oriented network unlike connection less networks like IP. So, it is more reliable. Bandwidth Allocation: MPLS networks allow for dynamic bandwidth allocation and hence can be used to provide bandwidth on demand (for a specific period etc) to customers. Further, rate limiting and other bandwidth management parameters allow a certain bandwidth to be dedicated for mission critical applications.

15. MPLS port and loop rates were higher than expected. Had the network been more geographically diverse, this factor would have been less noticeable, but for sites that were all close together and yet some distance from the closest POP, the pricing was out of line. MPLS requires greater IT overhead to manage all of the routers at each site. The customer was looking to decrease the IT burden, not increase it.

17. An Internet Leased Line is usually a dedicated line which offers direct connectivity to the Internet. This is done by connecting the nearest service provider nodal point and the customer premises with a dedicated copper line, optical fiber cable, radio links

19. Internet Leased Lines offer same speed for both uploads and downloads (symmetric connectivity), while in broadband (through DSL technology) the speeds are always optimized for downloads and the upload speeds are much lesser. etc. all of which are used by medium and large businesses regularly. Generally, broadband connectivity is shared with multiple users in a locality. Broadband plans generally denote the best bandwidth that can be attained and not the assured bandwidth levels. But a 2 Mbps Internet Leased Line should give 2 Mbps of performance as it is a dedicated connection without any sharing.

20. G-4 MUX MLLN VMUX

22. P.C.M stand for pulse coded modulation. A dedicated phone connection supporting data rates of 2.048Mbits per second. An E- 1 line actually consists of 32 individual channels, each of which supports 64Kbits per second. Each 64Kbit/second channel can be configured to carry voice or data traffic.

23. 32 Timeslots Total. Each channel holds 8 Bits. Each channel repeats 64,000 times a second (64 Kbps). 30 TIME SLOTS for voice calls.

24. The MLLN is an integrated, fully managed, multi-service digital network platform through which service provider 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 QoS (Quality of Service), high availability and reliability. The Network Management System also supports Service Provisioning, Network Optimization, Planning and Service Monitoring. The system offers features such as end to end circuit creation and monitoring, Circuit Loop Test and fault isolation, Alternate re- routing of traffic in case of trunk failure, Software programmability of NTUs, etc.

26. Circuit fault reports generated proactively. On demand the bandwidth can be increased. Protection against the failure of the circuit. Centrally managed from Network Management System. Easy re-routing and configuration
