Course Objectives

Introduction to Cisco Voice Design Concepts

  • differentiate between analog and digital signaling and recognize their impact on voice transmission.
  • identify the components and features of the telephone network.
  • recognize how PSTN numbering plans work and identify the role of PSTN features and how they are implemented.
  • identify reasons for implementing converged voice and data networking and identify the components in converged networks.
  • identify the most common IP telephony designs and show how voice-enabled routing is utilized in its implementation.
  • identify issues relating to voice in packet networks and list and recognize the most frequent coding and transport control mechanisms.
  • identify Voice over Frame Relay and ATM implementations and list their benefits.
  • list and identify components of packet voice networks in enterprise networks.
  • identify and minimize network delays, and estimate the number of simultaneous calls using a certain coding type on a WAN link.
  • list the QoS mechanisms and identify their impact on voice quality.
  • identify network delay and bandwidth issues and determine how to resolve them in a given scenario.
  • differentiate between on-net and off-net calling and outline how they can be used to minimize voice communication costs.
  • calculate the probability of a voice call being blocked and determine the number of circuits required for an acceptable Grade of Service.
  • recognize the impact of coding mechanisms on resource planning and identify the key considerations in planning WAN capacity for voice.
  • identify best practices for IP telephony capacity planning.
  • show the effect of transporting voice traffic across data networks in a given scenario.
