The most significant feature is the integrated EDA
Management Proxy (EMP) functionality. EMP enables
the Ethernet Controller Node to reduce management of
IP addresses to just one management IP address per
Ethernet Controller Node, independent of the number of
subtended IP DSLAMs.
Ethernet Controller Node ECN330 is a natural
aggregation point for the EDA 1200 series of IP
DSLAMs based on EDN312x, as it contains 24 100
Mbps Fast Ethernet downlink ports.
Combined with ESN410/ESN212 for traffic aggregation,
ECN330 may also be used for management of VDSL2
nodes or combined ADSL/VDSL nodes in fixed or
flexible topology scenario.
ECN330 is equipped with the built-in EDA Management
Proxy (EMP) that is capable of managing up to 250
embedded nodes or 2500 VDSL2/ADSL2+ lines.
ECN330 can also be used as a regular Ethernet switch,
as it is possible to disable the EDA Management Proxy
(EMP) by command either for all ports or on a per-port
basis.
The Ethernet Controller Node offers the following
functionality - all in one box:
• Aggregation switch
• 24 electrical Fast Ethernet ports
• Two combo uplink ports, either as
− Two electrical 10/100/1000 Mbps or as
− Two 100/1000 Mbps optical SFP
• One electrical 10/100/1000 Mbps uplink (ECN330)
• Built-in Power over Ethernet
• EDA Management Proxy (EMP) application designed
to aggregate management traffic from all EDA
elements attached
− The EMP allows daisy-chaining of up to 7 ECN330
switches for increased management capacity
− Management of up to 250 embedded nodes or
2500 VDSL2/ADSL2+ lines
− One IP address
• Downgrading to basic switch functionality by
disabling EMP
• L2MPLS (Martini draft) for tunneling (ECN330)
• Layer 3 routing features (ECN330)
Aggregation Ethernet switch ESN212
The 12-port Gigabit Ethernet aggregation switch
ESN212 is part of the new generation EDA 1200 series —
designed for installation in rough environments close to
the end-user.
Ethernet switch ESN212 is a 1st level aggregation switch
with eight electrical Gigabit Ethernet ports, four optical
Gigabit SFP ports and two separate connectors for
redundant -48V powering.
ESN212 is rail-mounted and hence ideal for placing in a
remote cabinet aggregating up to eight IP DSLAMs
(EDN612 as well as EDN312) on the electrical Gigabit
ports, using one or more of the optical ports for uplink
connection to the central office. ESN212 could,
however, also be part of a fiber ring topology, utilizing 2
or more of the 4 optical SFP ports.
ESN212 is equipped with a DIP-switch that allows the
telecom operator to assign a unique identifier to the
switch for operation in a flexible topology setup with
ECN330.
Aggregation Ethernet switch ESN108
Ethernet switch ESN108 is a 1st level aggregation
switch with eight electrical Fast Ethernet ports and one
optical uplink port. ESN108 will detect the uplink
capacity from the SFP module installed and configure
the uplink accordingly for 100 Mbps Fast Ethernet or 1
Gbps Ethernet.
