The UNIVERGE™ NEAX® 2400 Internet Protocol eXchange (IPX), the newest member of the UNIVERGE NEAX family, fuses existing NEC technologies with dynamic advancements in hardware and software to satisfy the most stringent system requirements.

NEC also introduces the next level of Internet Protocol (IP) medium -- peer-to-peer switching -- into the UNIVERGE NEAX 2400. This capability allows the UNIVERGE NEAX 2400 to provide all of NEC's networking services and Dterm Series E digital telephone features when deployed over an IP network.

Peer-to-peer switching means the stations participating in a call are connected directly to each other through the IP network. The voice signals travel through the IP network but do not "go through" the switch as they do in traditional telephony. The fact that the UNIVERGE NEAX 2400 IPX can function in and support a "hybrid" network with traditional digital/analog switching, IP/TDM switching and pure peer-to-peer IP switching means the users can continue to utilize their existing equipment while they phase in IP Telephony and lay the foundation for future networks.
