Network Protocol Data Intelligence. Also called “Interworking,” it is a software product that operates within Excel’s Call Control (Layer 4) and Services (Layer 5) call processing layers. NPDI is meant to enhance Excel’s call processing product offering by allowing call processing layers (specifically Layers 4 and 5) to perform advanced analysis, generation, and conversion of Network Signaling (NS) Layer 3 information.

A collection of newer network components, such as terminals, gateways, gatekeepers, and multipoint control units (MCU) that interoperate with other standards-compliant endpoints and networks by virtue of an H.323 gateway. The collection of all these network components, which are managed by a single Gatekeeper, is referred to as an H.323 Zone. A zone includes at least one terminal, and can include gateways or multipoint control units (MCUs), or LAN segments connected using routers. A zone has only one gatekeeper.
