Figure 15 Ethernet Access Node Structure
The ECN320 contains 24 10BASE-T/100BASE-TX RJ-45 ports and two
combo ports—10/100/1000BASE-T ports which operate in combination with
Small Form Factor Pluggable (SFP) transceiver slots.
The ECN330 contains 24 10BASE-T/100BASE-TX RJ-45 ports and two
combo ports—10/100/1000BASE-T ports which operate in combination with
Small Form Factor Pluggable (SFP) transceiver slots and an additional
electrical 10/100/1000BASE-T port.
The ECN330/ECN320 is used as the first and second level aggregation
switch in the EDA network (second level with ESN108 or ELN220 as first
level), while also supplying IP DSLAMs with DC power over the Ethernet
connections.
It has two power supply ports which establishes power redundancy.
As well as its Power-over-Ethernet capabilities, the ECN320 provides
comprehensive network management features, such as, multicast
switching, virtual LANs, and Layer 2/3/4 CoS services that provide reliability
and consistent performance for network traffic.
