Technical Concepts
Static and Adaptive Jitter Buffer
In the case of data transmission, packet loss should be as low as possible to guarantee data
integrity. Delays, however, do not play a significant role.
9.5.2 How the Jitter Buffer Works
The jitter buffer supports three different modes. Two of these are suitable for voice transmission
and one is for data transmission (for example, transparent fax, transparent modem or ISDN da-
ta):
● static jitter buffer for voice
● static jitter buffer for data
● adaptive (dynamic) jitter buffer for voice
The adaptive jitter buffer is specially designed for voice transmission. While the average packet
delay remains constant for the static jitter buffer, it is automatically adapted depending on the
situation in the case of the adaptive jitter buffer.
