IP Network Interface Series 3 Voice Coder Packet Rate Information

For the IP Network Interface Series 3 card there is a coupling between the Payload Type (codec) and Payload Size (packet rate). Unlike the VDAC-ONE card, the base packet rate (sampling) of a codec is different for different codecs. This implies that a Payload Size, which is defined in multiples of the base packet rate are specific to the Payload Type. The table below shows the relationship between the Payload Type and Payload Size on an IPN-3 card. It also shows a list of all Voice Coders supported by the IPN-3 card.
