The EDA Components

In order to clarify the concept of a stand-alone and embedded IP DSLAM
the EMP and non-EMP solution is explained below.
4.1.1 The EDA Management Proxy (EMP)
EDA Management Proxy (EMP) is a built-in application in the Ethernet
Controller Node ECN330/ECN320. EMP removes dependency of PEM
servers during start-up and restart, and reduces the number of IP
addresses needed in the management network as it defines the
ECN330/ECN320 and its connected network elements as one logical node
named Ethernet Access Node (EAN).
Figure 8 Example of an EAN
The EAN above shows a number of network elements connected to an
ECN330/ECN320. The local IP addresses of the network elements are not
visible in the management network, except for the IP address of the
Ethernet Controller Node. The ECN330/ECN320 maintains the connected
network elements using local IP addresses.
