Introduction to the EDA 1200 System

2.2 EDA 1200 Realization

The EDA 1200 nodes are realized as telecom grade nodes. The basic principle

architecture of an Ethernet Access Nodes (EAN) is depicted in Figure 9 on

page 11.

Figure 9 EDA 1200 Access Node Basic Architecture Principle

The EAN is based on IP and Ethernet architecture. All units within the EAN

have private IP addresses and are managed by an ECN. A management

system can mange the whole EAN through the ECN. The whole EAN will

appear in a management system as one large node with many End-user lines.

All End-user lines are terminated by a Line Termination Unit (LTU). The LTU

can be based on different drop technologies such as DSL, Fiber or POTS. The

traffic can be aggregated through the ECN or by another Ethernet Switch unit.

2.2.1 Network Architecture

The following figures illustrate an EDA 1200 access network with a variety

of Ethernet Access Nodes.

The internal switching unit in the ECN is used to aggregate all End-user traffic

as well as management traffic to the embedded EDA 1200 nodes in Figure 10

on page 12. Narrowband is supplied as baseband POTS.
