IMX/IPX on opposite side which do not support peer-to-peer connections. The IP-PAD is required for
connections between IP terminals and IP trunks. A maximum of one IP trunk card can be
accommodated per PIM with a maximum of eight IP trunk cards per system. Voice compression of
G.729a (8 kbps) and G.723.1 (5.3 kbps / 6.3 kbps) can be provided by the IP trunks with VCT cards.

IP packets and transmit them over the data network. All CCIS centralized and transparent features can
be used connecting up to 255 NEAX systems in a network for a total of 130,560 station ports.
