2 Agenda Conventional telephone and data networking Voice data convergence IP telephony PBX based IP telephony Implementing convergence networks

3 Data Network NMS Internet LAN WAN LAN

4 Telephone Network NMS Internet LAN Copper PBX PSTN NMS WAN LAN Copper PBX

5 Conventional Network Infrastructure Separate Telephone and Data Network Separate Set of Infrastructure : High Total Cost of Ownership Extremely Complex Network : Difficult to Upgrade and Expand Network Need Multiple Team of Administrators : Difficult to Administrate and Operate Network

6 Agenda Conventional voice and data networking Voice data convergence IP telephony PBX based IP telephony Implementing convergence networks

7 What is Voice Data Convergence? VOICE and DATA on the Same Media : LAN, WAN

8 Voice over Data Network Technology WAN Solution : VoATM, VoFR, VoIP LAN Solution : VoATM, VoIP Valued Added Application : VoIP Voice Over IP Technology is Total Solution in Voice Data Convergence

9 IP Technology Drivers Internet Explosion Everything Over IP Wave : IP as the main protocol for Data, Voice, Desktop Video will run on IP. IP is on the way to do what ATM and ISDN failed to do : Integrate all the services. Same Technology for Internet and Intranet Cost Savings : People try to lower the Telecom Costs H.323, SIP is Main Standard

10 Convergence Communication Data Voice Single Infrastructure Video Internet Packet-Based IP Network Integration of data, voice, and video services into a single packetbased IP infrastructure Both in enterprise and public service provider network infrastructure

11 Converging voice and data onto a single network is the major strategy on which enterprises must embark if they are to resolve the conflict between network budgets and desired network capabilities.

12 Benefits of Voice Data Convergence Reduction in Network Infrastructure Cost Converging Multiple Network Infrastructure to a Single IP-based Network. Lower System Expansion Cost Eliminating Long Distance Call Charge Reduction in Staffing and Administration Cost Easy to Integrated with New Application : Call Center, UC, IVR, Enterprise Applications

37 Agenda Conventional voice and data networking Voice data convergence IP telephony PBX based IP telephony Implementing convergence networks

38 Implementing convergence network Has enough bandwidth to carry VoIP traffic Has implemented a QoS strategy Power In-Line Enable

39 Why QoS? Can t we just increase Bandwidth? Increased bandwidth reduces queuing delay, however Some applications such as VoIP: Require consistent Delay Performance Behave poorly under bursty network conditions QoS provides the ability to read, alter, prioritize and tag or mark IP traffic based upon information in the IP header The ability to prioritize traffic allows for: Better voice quality when using IP telephony Better quality streaming videos and video conferencing The ability to offer levels of service based upon bandwidth allocation

40 QoS Implementation Edge Switch Classification Rate Limit Voice Traffic : High Priority Internet Traffic : Low Priority Core Access Switch High Medium Low Core Switch : -Queuing : High 60% Medium 30% Low 10% ERP Traffic :Medium Priority

41 Wire-rate Intelligence & One Touch Manageability Voice, Video, Data Services differentiation at Wire speed or every thing will be slow down L2/L3/L4 Wire rate classification what ever the action QOS, rate limiting, mapping...filtering, NAT...Load Balancing One Touch Manageability to easily deploy complex functions and save on network operator costs Automatic settings of QOS for IP Phones and servers across the entire network with a few clicks Unified platform to support data and voice management

42 QoS Policy Management What Allows admin to easily configure QoS settings Automatically replicates to all other switches with a click Two modes - easy and expert Benefits Reduces man hours configuring network Ensures voice throughput Configurations easily updated QoS QoS QoS QoS QoS QoS Configuration Network Manager

43 What Power In Line Enable IP equipment powered directly from network port 802.3af standards based Chassis IP power capable from day one Benefits Reduces electrical cabling Allows equipment placement where no electrical outlets exist Embedded power management Auto-sensing of termination equipment IP PBX In-Line Power Comm Line IP Phones Network
