Description of the EAN
As described in the introduction the ECN is the key element in the EAN.
Several nodes can be connected to the ECN (see section 2 on page 5):
The nodes can be combined in various ways to form an EAN. Figure 10 on
page 26 illustrates the logical structure of the management and subscriber
traffic in the EAN.
A logical structure in this context means that the EAN does not necessarily
contain all the elements. The basic topologies supported by the EDA sys-
tem are described in more details in this section.

Ethernet Access Node Structure
The Ethernet Node Controller (ENC) manages all the embedded nodes.
From a management point of view, the switching unit is also an embedded
node, even though it is located and integrated in the ECN.
The ENC is the only element communicating directly with the Public
Ethernet Manager (PEM). Using the
EDA Management Proxy
(EMP) func-
tion, the ENC forwards the communication to and from the embedded
