11Chapter Multiplay broadband Elements _ Function

• Broadband Remote Access Server (BBRAS)


  Component of broadband access network

  
• Gigabit and Fast Ethernet Aggregation Switches (LAN Switches)


  Component of broadband access network

  
• Digital Subscriber Line Access Multiplexers (DSLAMs)


  Component of broadband access network

  
• SSSS/SSSC (Subscriber Service Selection System/ Centre)


  Component of broadband access network

  
• Servers for AAA, LDAP at Pune


  Component of broadband access network

  
• Provisioning and configuration management at NOC

  Component of broadband access network

  
• Broadband Network Architecture (NIB 2)

  1. Access

  2. Distribution

  3. Metro Core

  4. Core

  
• Core


  • MPLS based IP infrastructure in 71 cities being expanded to 106 cities, as part of Project 1 of NIB-II
• Distribution + Metro Core


  • From Tier 2 Switch onward (towards the network)
• Access


  • DSLAM to user
• Network diagram of NIB-II shows the deployment of network elements and their arrangement in different types of cities across the country
• Multiplay is expansion of DSL Broad band Network of BSNL
• Network Designed to cater to Multiplay services
• DSLAM continue to work in star topology
• Uplink bandwidth of DSLAM is min. 1+1 GE
• The Aggregation Network for Multiplay will be in Ring Topology based on RPR instead of the existing tree structure of Project 2.2
• Connection Admission Control and hierarchal QoS implementation
• New applications like automated subscriber installation and on going support is introduced
• The Traffic aggregation to Core Backbone happens across 100 cities instead 23 cities of Project 2.2
• Hardware


  • CPE (UTStarcom Contract Manufacturer SemIndia)
  • DSLAM (UTStarcom)
  • RPR (UTStarcom)
  • OCLAN (ZTE)
  • BNG (Redback)
  • Servers (SUN)
• Miscellaneous Components


  • Converters
  • DSL Tester
  • Desktop/Laptop

  • eMS for above Hardware
• Application / Server Infrastructure


  • NOC &DR
  • Regional POP
  • Aggregation Network
  • Access Network
  • Other

  
• TVOIP (IPTV)


  Delivers television programmes to households via broadband connection using Internet protocols
• TVOIP (IPTV)


  • Requires a subscription and IPTV set-top box (STB)
  • Typically bundled with other services like Video on Demand (VOD), Voice Over IP (VOIP) or digital Phone, and Web access
  • IPTV viewers will have full control over functionality such as rewind, fast-forward, pause, and so on
• VOIP


  Technology used to transmit voice conversations over a data network using the Internet Protocol
• NMS (Five Layer Model)


  • Fault
  • Configuration
  • Accounting and Asset Management
  • Performance
  • Security
