The LSE node is a regular Hub node with additional functionality particular to location services
applications.There is also a distinction between RAN Nodes in NXD vs. CXD systems. In an
NXD system, there is a one to one relationship between CPUs and nodes because each NXD
RAN has its own CPU where its own MIBs reside. In a CXD system, the term RAN Node refers
conceptually to the individual RAN but all RAN MIBs reside on the Hubmaster CPU.
1.4.3 Element Management System (EMS)
The Digivance Element Management System is a Web based system that provides the various
control and monitoring functions required for local management of each CXD/NXD system.
The user interface into the EMS is a PC-type laptop computer loaded with a standard Web
browser.
Figure 6 is a diagram showing the relationship of EMS to the Digivance MIBs
described in the previous topic.
