Course Brief

Fixed line voice revenues still account for over 2 Bn per quarter in the UK alone, with mobile revenues still larger. To make the most of this revenue voice providers must ensure their network costs are controlled to maximise profits. Effective capacity planning is the key to this process.

This course addresses the traditional techniques for sizing voice networks and the challenges in sizing for new technologies such as voice over IP

Course Prerequisites

  • Capacity Planning: Tools and Methods

Course Audience

  • Network Capacity Planners
  • Voice Network Engineers
  • Network Managers
  • Demand Planners
  • Voice Operations Staff

How Your Organisation Will Benefit

Attending this course you will learn:
  • How to generate of traffic data when little or no data is available
  • Traffic demand generation techniques
  • Traffic forecasting techniques.
  • Techniques to size voice links to minimize network expense without significantly impacting revenue
  • The appropriate capacity planning techniques for your company
  • How to reduce operational costs through accurate capacity planning
