Packets are transmitted at set intervals. Packet Delay Variation is the maximum deviation from the nominal time the packets are expected to arrive at the far end device. IPmux-1 has a buffer that compensates for the deviation from the expected packet arrival time to prevent IPmux-1 buffers from emptying out or overflowing.

Packet Delay Variation is an important network parameter. Large PDV (exceeding the jitter buffer configuration) will cause receive buffer underflows and errors at the E1/T1 level (see Figure 1-18).

To compensate for large PDV, configure the PDVT (jitter) buffer to a higher value.
