The lower the average and maximum delay is set, the more natural voice transmission will sound to subscribers. However this increases the danger of packet loss and in turn the danger of information loss and distortions. Higher delay values mean less packets get lost, however, it takes longer until a subscriber hears what the other subscriber is saying. Extensive delays can lead to communication difficulties. The following diagram illustrates this:

When the HG 3500/75 board is being generated, generous values are set with which most installations will start without any problem. In many cases, these values can then be reduced selectively.
