NEC 2000 IPS
The 2000 IPS system provides a rich set of existing NEC PABX features together with pure IP telephony switching, thus allowing either;
1) a full IP solution,
2) a partial IP solution, or
3) a complete traditional TDM system with the option to go IP at any time.

With the ability for peer to peer IP telephony, the NEC 2000 IPS physically integrates its PABX switching fabric with a LAN/WAN environment for the routing of trunk traffic or for the local / remote connectivity of desk top handsets.
The NEC 2000 IPS also supports intelligent trunk routing with Common Channel Interface Signaling (CCIS) for connection to other traditional NEC PABX's plus full feature transparency peer to peer over an IP Network to other NEC 2000 IPS Systems.

Defining Peer-to-Peer
Peer-to-Peer switching means that the stations participating in a call are connected directly to each other through the IP network. The signals travel through the IP network but do not "go through" the switch as they do in traditional telephony.
The fact that the NEC 2000 IPS can function in and support a "hybrid" network with traditional digital/analog switching, IP/TDM/IP switching and pure peer-to-peer IP switching means that users can continue to utilize their existing equipment while they phase in IP telephony and lay the foundation for future networks.
Reduced Costs of Peer-to-Peer IP Connectivity
The NEC 2000 IPS retains all the features of the popular IVS 2000, while offering significant cost savings associated with peer-to-peer telephony such as:
- Converged WAN Infrastructures: Pay for the service and maintenance on one network rather than two. By transporting voice signals across the WAN as IP packets, users can integrate their voice traffic with their data traffic.
- Converged LAN Infrastructures: Establish voice calls across the 10/100 Ethernet Local Area Network utilizing the existing plat cabling and allowing single cable termination to the desktop.
- Reduced Equipment Requirements: Reduce the need for cards while minimizing the required plant footprint as well. In traditional TDM telephony, a single port is required for each station and each tie line connection. With IP connectivity, multiple calls are controlled through a single 10/100 Ethernet port while voice travels directly between the user telephones.
Investment Protection with the 2000 IPS
Even if you're not ready to migrate to 100% IP telephony immediately, the NEC 2000 IPS supports traditional circuit-switched telephony (Time Division Multiplexed) on both the trunk and line sides. This simultaneous compatibility allows current users of NEC systems to retain their existing TDM equipment (thus protecting their original investment) as they begin to make the migration to pure IP telephony. All previous versions of NEC 2000 switches can be upgraded to the 2000 IPS easily and inexpensively.
Enhancements of the NEC 2000 IPS
The 2000 IPS supports both pure IP switching (peer-to-peer connections) and Time Division Multiplexing (TDM).
The pure IP switching is provided for communications between IP telephony devices, while the TDM switching is provided for communications between legacy stations/trunks. Connections between IP Dterms and legacy stations/trunks are made via the new IP-PAD card, which converts packet-based voice data to TDM based voice date, and vice versa.
Voice Compression Support for IP Calls
The 2000 IPS supports compression for calls between IP telephony devices as well as calls through the IP-PAD. Compression substantially reduces the amount of LAN/WAN bandwidth required for the voice communications.
One-Board Main Processor with Integrated Functionality
The 2000 IPS Main Processor (MP) is the heart of pure IP and TDM based connections. The MP employs a high speed CPU with System On Chip (SOC) technology. With it's extra processing power the MP integrates the following:
- Device Registration Server (DRS) - provides a log-in/log-out management of IP devices including registration and authentication. Also, the built-in DRS can be inter-worked with DHCP server to provide easy administration of IP addresses.
- Open Application Server (OAI) functions for Computer Telephony applications, such as Q-Master.
- On-board Ethernet Interface daughter card, saving on utilizing an additional slot space in a PIM. This Ethernet card is linked with the LAN for call control processing of IP Devices and inter-work with Maintenance Terminals and OAI server applications.
- Built-in Firmware Processor (FP) capability within the MP negating the need for a separate FP package in the first PIM
- Access for a direct connection to an external music on hold source.
- Provides an SMDR output for a call accounting applications option, and MCI (message center interface) for voice mail integration.
