It is designed to offer greater centralised functionality foroperators, giving them access to Enterprise Edge features over multiple combinednetworks.Note: The DPNSS feature is dependent on the market profile loaded on yoursystem and whether on not you have a software keycode to enable thefeature.DPNSS 1 allows an Enterprise Edge local node, acting as a terminating node, tocommunicate with other PBXs over the network. For example, corporate officesseparated geographically can be linked over DPNSS 1 to other Enterprise Edgenodes, bypassing the restrictions of the PSTNs to which they may be connected.This allows connected Enterprise Edge nodes to function like a private network,with all features of Enterprise Edge accessible.DPNSS 1 features can be used on any Enterprise Edge telephone set.
