4 The EDA Components

The components of the EDA solution are described in further detail in the

following sections.

The nodes or components in an Access Domain are all connected to the

same Ethernet, which carries both end-user and management traffic. The

EDA system is built on the following components, which can be combined

to form a specific EDA solution:

• IP DSLAMs - EDN312 and EDN288

• Switches - ESN108, ESN310, ESN410 and ELN220

• Ethernet Controller Node - ECN320 (An ESN310 with built-in EDA

Management Proxy (EMP) function) and ECN330 (A Layer 3 switch

with built-in EDA Management Proxy (EMP) function)

• Subracks - Micro Subrack, Small Subrack, Medium 288 Subrack

• Cabinets - Outdoor Cabinet

• Converters - FE-E1 Converter (EXN104) and Ethernet Gateway

EXN401/410

• Power Node - EPN102

• Management system - Public Ethernet Management system (PEM)

The components are described in more detail in the following.

4.1 The IP DSLAMs

The EDA solutions are based on IP DSLAMs, which are available in a 12-

line, a 24-line version and a 288-line version. The IP DSLAMs are powered

over the Ethernet cables and both data and power is conveyed in the same

cable.

The IP DSLAMs can be aggregated in the network by using a 24-port

switch ESN310, without built-in EDA Management Proxy. The IP DSLAMs

can also be aggregated by the 24-port Ethernet Controller Node

(ECN330/ECN320), in which case the EDA Management Proxy is used.
