  • Page 97: Fundamentals

    Fundamentals Fundamentals VoIP makes the transmission of voice and telephony signalling via IP (“Internet Protocol”) possible. After a connection is established, the terminal collects voice data (PCM data), which is then sent to the receiver using an IP packet. PCM data can also be compressed to save bandwidth.
  • Page 98 Fundamentals The length of the voice-data packets must therefore be adjusted to the requirements of the transmission medium. Shorter voice- data packets can be sent if a direct ethernet connection exists. If an 64 kbit/s ISDN line is to be used for transmission, then longer voice-data packets should be used.

  • Page 99: Voice Quality

    Fundamentals Voice Quality The achievable voice quality depends on various factors. It is pos- sible to optimise voice-data transmission on an existing network using the available configuration settings. Measuring the network quality may also help. The following comparison provides a guide to voice quality with specific quality levels: Quality Levels for Voice Transmission with VoIP Level...

  • Page 100: Optimisation

    Fundamentals The achievable voice quality also depends on the packet propaga- tion delay and the packet loss between the terminals involved. These parameters can be determined using the “ping” pro- gramme. Note: Measurements made with “ping” are round-trip propaga- tion delays. Divide the maximum value displayed by two.
