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.
