4. Reset the IAD (page 15) when you finish voice path configuration.

When you choose a specific voice gateway, the IAD displays option E on the Main menu specifically for the voice gateway you’ve selected. Proceed to the section for configuring a specific gateway:

Inter-arrival jitter is the difference in relative transit time for two packets. It is the difference between the packet's RTP time-stamp and the receiver's clock at the time of arrival of the packet.

As shown in the equation below, this is equivalent to the difference in the relative transit time for two packets: the relative transit time is the difference between a packet's RTP time-stamp and the receivers clock at the time of arrival, measured in the same units.

If Si is the RTP time-stamp from packet i and Ri is the time of arrival in RTP time-stamp units for packet i, then for two packets i and j, D may be expressed as:

D(ij) = (Rj -Ri) -(Sj -Si) = (Rj -Sj) -(Ri -Si)

The interval jitter is calculated continuously as each data packet i is received from source SSRC-n, using this difference D for that packet and of the previous packet i-1 in order of arrival (not necessarily in sequence), according to the formula:

J = J + ({D (i-l, i)} -J)/16

The Jitter Delay should only be set by a Network Administrator. To set jitter delay (0 to 50 ms—default 0 ms), follow these steps:

1.Type J on the Voice Configuration menu to select Set Jitter Delay.

2.The IAD displays this prompt:

Enter number of ms to delay [10]:

Type the delay value and press Enter.

3.The IAD saves the jitter delay and displays the Voice Configuration menu so you can continue with other voice path configuration.

4.Reset the IAD (page 15) when you finish voice path configuration.
