The IPN-3 card meets all of the software requirements specified for the IPN-2 card with the following exception:
• The Mindspeed modules do not have a software readable serial number - which is not necessary.
The following are new requirements for the IPN-3 card:
• The IPN-3 card interoperates with the IPN-2 card
• The IPN-3 can pass RTP traffic with the VDAC-ONE running RTP codecs G.711, G.723.1 and G.729
The IPN-3 can reside in the same chassis as an IPN-2 and a VDAC-ONE.
