111. vals Packet Delay Variation is the maximum deviation from the nominal time the packets are expected to arrive at the receiving device The TDMoP IC controls a buffer that compensates for the deviation from the expected packet arrival time to prevent buffer overflow or underflow Packet Delay Variation is an important network parameter Large PDV exceeding the jitter buffer configuration causes receive buffer overflow or underflow and errors in the recovered E1 T1 signal To compensate for large PDV the PDVT jitter buffer should be configured to a higher value Figure 1 11 Packet Delay Variation Packets Leaving Near end TDMoIP Eval Board i Packets Arriving at Far End TDMoIP Eval Board zDD Te nA t 1 4 11 1 Differential Time The TDMoP IC is equipped with a Packet Delay Variation Tolerance PDVT buffer The PDVT buffer is filled by the payload of incoming packets and emptied to fill the outgoing E1 T1 or serial data stream The jitter buffer depth is defined by the Rx_max_buff_size parameter When the jitter buffer level reaches the value of Rx_max_buff_size an overrun situation is declared The Differential Time parameter defines the amount of data to be stored in the jitter buffer to compensate for network delay variation This parameter has two implications e Differential Time defines the IC s immunity to network packet delay variation e The data arri
