EDA 1200 System Overview

4.2.1 Ethernet Node EFN324

The EFN324 is an Ethernet Access

node. It has 24 10/100 Mbps Ethernet

downlink ports and two 1000 Mbps

Ethernet uplink ports. The EFN324 is

prepared for 19” rack mounting. The

EFN324 has hardware versions for

either optical or electrical downlinks.

End-users are connected directly to the

EFN324, which has extensive security

capabilities (both for the End-user and

for the network). The EFN324 can also

act as multicast proxy.

The EFN324 is available in the following

variants:

• EFN324f: Single mode Single fiber optical termination

• EFN324df: Multimode Dual fiber optical termination

• EFN324c: Electrical Ethernet termination (Cat5, indoor only)

4.3 Ethernet switches

The Ethernet switch is in principle a standard Layer 2 switch that aggregates all

connected IP DSLAMs. The connection from Ethernet switch to IP DSLAM is a

100 Mbps full duplex Ethernet (100Base-TX). Uplink connections can either

be 100 Mbps full duplex or 1000 Mbps full duplex. All EDA 1200 switches

include PoE.
