EDA 1200 System Overview

4.4.2 Ethernet Controller Node ECN330

Ethernet Controller Node ECN330 has 24

tributary (downlink) ports of the 10/100

Mbps Fast Ethernet type, two combo

aggregate (uplink) ports (either two

electrical 10/100/1000 Mbps Ethernet

ports or two 100/1000 Mbps optical SFP

fiber ports), and an additional electrical

10/100/1000 Mbps aggregate Ethernet

port.

ECN330 supports a number of advanced features like 4k VLAN, 16k MAC

table, full link aggregation, and Layer 3 routing.

ECN330 also supports Layer 2 MPLS for tunneling and a number of redundancy

protocols, for example Rapid Spanning Tree Protocol (RSTP), Multiple

Spanning Tree Protocol (MSTP) and Ethernet Automatic Protection Switching

(EAPS).

ECN330 has built-in Power over Ethernet (PoE) functionality for power

distribution to the connected IP DSLAMs. It is prepared for 19” rack mounting

and has built-in fans that can be replaced without service interruption.

ECN330 also includes the EDA Management Proxy (EMP) that reduces

the management of IP addresses to one single IP address per ECN330,

independent of the number of IP DSLAMs aggregating to each ECN330.

The ECN330 may be configured to disable the EMP functionality for pure switch

operation. Configured as a switch, the ECN330 is denoted ECN330-switch.

ECN330 is equipped with dual power inlets enabling power redundancy.

The ECN330 is available in two variants, the ECN330a, which is

NEBS-compliant, and the ECN330 which is not.
