Acronym for Network Address Translation. This is a general term for the process of IP rewriting address information in communication between peers with private and public IP addresses.
The numbering plan can be set up in a tree like structure of numbering nodes. Each node can have distinct extensions only. However, different nodes can have identical extensions. All numbering nodes build up the Numbering Node Tree.

:
Acronym for Network Termination.
Most telecommunication network interfaces are asymmetric. One side implements the network end of the interface, thus called network termination. This is the interface provided by the network provider (a.k.a. carrier) where the customer connects his network equipment. The other side implements the network customers equipments end of the interface. This side is usually called TE (terminal equipment).
Some interface implementations (such as e.g. innovaphone's ISDN interfaces) support both sides. The interface is then said to run in NT-mode or TE-mode.
A scope in the numbering plan which requires all extensions in this scope to be distinct. Numbering nodes are structured hierarchically in a node tree.
Numbering nodes are separate and independant from PBXs.
