Introduction

Broadband access is known to be the fastest growing
technology in the telecommunications history.

With the EDA broadband access concept, Ericsson has
for several years demonstrated technology leadership
on the broadband market — First, by introducing the
world’s first Ethernet-based IP DSLAM, then by
constantly adding new and innovative features to secure
an optimal end-to-end solution.

Now Ericsson takes the next step by introducing a cost­efficient, environmentally hardened VDSL2 solution.
Ideal for fiber-deep deployment close to the end-user
and perfectly suited for migration on existing
installations, as well as for new customers.

Since the early EDA 1200 days, Ericsson has been
shaping and promoting the IP and Ethernet-based
architecture. The Ethernet-based architecture (TR-101)
has been standardized by DSL Forum, and is seen as
the future architecture for telecom operators for years to
come.

Market shares have been constantly growing with EDA
1200 and leading European customers have selected
EDA 1200 as their preferred technology.

EDA 1200 overview

The EDA 1200 solution (previously called EDA Box)
deploys an access network with switched Ethernet and
a number of access drop technologies. The following
sections describe the components of the EDA 1200
solution with emphasis on the cornerstone of the
system - the IP DSLAM.

EDA components

The EDA solution comprises a number of components
that allows telecom operators to offer a full-featured
access solution:

• 12, 96, 144 and 288-line ADSL/ADSL2/ADSL2+ IP
DSLAMs (EDN312, EDN144 and EDN288)

• 24-port fiber access nodes (EFN324f, EFN324df and
EFN324c)

• 24-port Ethernet Controller Node (ECN330)

• 8-port and 24-port Ethernet switches with power over

Ethernet (ESN108 and ECN330 in switch mode)

• 12 port Gigabit Ethernet aggregation switch (ESN410)

• 2-port Ethernet Power Nodes (EPN102)

• Fast Ethernet to E1/T1 converter (EXN104)

EDA 1200 4.0 introduces a new generation specialized
for VDSL2 rollout. The new EDA 1200 is environmental
hardened and presents a new look and feel as well as
new broadband features:

• 12-line VDSL2 IP DSLAM (EDN612)

• 12 port Gigabit Ethernet aggregation switch (ESN212)

• 10-port Ethernet Power Node (EPN210)

• 24-port cat5 access node (EFN324c)

• 24-port fiber access node for multimode/dual fiber

(EFN324df)

IP DSLAM with high functionality

The EDA 1200 IP DSLAM is available as a complete all­in-one system with a unique scalability from 12 to 288
lines. The IP DSLAM is built on Ethernet technology
(TR-101). In essence, the IP DSLAM terminates the DSL
line, and aggregates the traffic into the access network
using standard Ethernet uplink connections.

The limited physical dimensions of the EDA 1200 IP
DSLAMs are secured without compromising
functionality. On the contrary, the IP DSLAM is fully
functional and designed using state-of-the-art
components, enabling easy SW updates for new
functionality support.

The IP DSLAM complies with all relevant DSL
standards, and interoperability is constantly verified
against the world’s leading CPE modem and chipset
vendors. All the DSL line coding is included in one
software package, making updates easy to
administrate. EDA 1200 supports VDSL2 as well as
asymmetric ADSL, ADSL2, and ADSL2+ including:

• VDSL2 Annex A for North America (POTS and ISDN)

• VDSL2 Annex B for Europe (POTS and ISDN)

• ADSL Annex A for POTS support

• ADSL Annex B for ISDN support

• ADSL Annex M for support of enhanced upstream

• ADSL Annex L for Reach Extended

EDA 1200 provides an option for enabling L2 power
down per line, which makes it possible for the operator
to save up to 25% on the power budget for a complete
IP DSLAM. The most significant benefit is obtained
when the lines are trained to maximum speed and the
CPE is at a distance of 10,000 feet from the IP DSLAM.

(the “blue box“) next to the new generation of EDA 1200,

the environmental hardened IP DSLAM EDN612 (right).

EDA 1200 allows PSD shaping to optimize the power
distributed from the IP DSLAM. This option is used
when an operator has both central-based equipment
and remote-based equipment in the network. The
solution offers six fixed options: two for standard, two
for central-based, and two for remote-based
equipment. Radio frequency interference notching
makes it possible to restrict parts of the frequency band
when training the DSLAM for the requested bandwidth.

The IP DSLAM is an environmentally friendly product,
designed in accordance with the ISO14001 standard
and produced with regards to a minimum use of lead
and halogens in the product. The IP DSLAM conforms
to the rigid Bellcore GR-63-core.

Solutions with IP DSLAM EDN612

The 12-line IP DSLAM EDN612 is the cornerstone of the
new EDA 1200 product line specialized for VDSL2
rollout with a fallback option for ADSL/ADSL2/ADSL2+.
EDN612 is supported by the 12-port Gigabit
aggregation switch ESN212; and together they form an
unmatched scalability and deployment opportunity. This
new generation of EDA 1200 is environmental hardened
and designed for cost-effective installation close to the
end-users in remote outside plants, where it demands
very little protection against weather and rough
environments.

POTS and ISDN services

For the support of underlying telephony services POTS
and ISDN a external splitter solution is available as well,
compliant to the EDA installation method.

Subrack solutions with EDN612

Both 19” and ETSI (21”) wide subracks are available for
up to 96 subscriber lines per subrack. Subracks include
built-in cable management and air guides and it is
possible to mix EDN612 IP DSLAMs, ESN212 switches,
and external splitters. An optional Power Distribution
Node EPN210 is also available, which also opens the
possibility of aggregating EDN312 IP DSLAMs for a
cost-efficient ADSL2+/VDSL2 upgrade of a remote site.

Below is shown a fully equipped 96-line ETSI subrack
solution without splitters equipped with eight EDN612 IP
DSLAMs, one ESN212 switch, and one EPN210 power
distribution node.

12-line VDSL2 IP DSLAM EDN612

EDN612 has 12 fully flexible lines capable of running
VDSL2, ADSL, ADSL2 or ADSL2+. EDN612 is available
with POTS front-end (EDN612p) or ISDN front-end
(EDN612i). Underlying POTS or ISDN services are
available with external splitter, and EDN612 is also
prepared for built-in splitter. Two electrical Gigabit
uplink connections that can be used for redundancy
ensure non-contention operation. EDN612 has a
separate connector for -48 V powering (Power over
Ethernet is not included in this product line). EDN612 is
rail mounted like the existing EDA 1200 product line.

Environmental aspects

The new generation of EDA 1200 is designed for
operation under extreme conditions (ETSI EN 300 019­1-3 Class 3.3 and GR-3108 CORE class 3) in order to
meet the requirement for VDSL2 equipment to be
pushed even closer to the end-user than ever before.
Hence, EDA 1200 can be placed in non-controlled road­side cabinets and other locations with high humidity,
dust and dirt, as well as the operating temperature
range cover temperatures from -40°C to +75°C, thanks
to an optimized cooling channel that easily transports
dissipated heat out of the box. In fact, the only
protection needed is shelter against rain, direct sunlight,
and objects of 1 mm and greater.

Migration from existing installed base

EDA 1200 meets the operator’s need for smooth VDSL2
rollout on remote outside plants. The new EDA 1200
designed for VDSL2 rollout is not only a stand-alone
product line; it also goes nicely in line with the existing
installed base of EDA 1200. The illustration below
shows the existing EDA 1200 on the left next to the new
generation EDA with front cabling.

Solutions with IP DSLAM EDN312

The 12-line IP DSLAM EDN312x is the cornerstone of
the existing EDA 1200 product line (the “blue Box”) and
it provides full support for ADSL, ADSL2 and ADSL2+.
The 12-line IP DSLAM EDN312x aggregates all the
incoming ADSL links onto one or two 100Base-T
Ethernet connections depending of the bandwidth
demand.

One innovative aspect of IP DSLAM EDN312x is the
power feeding over Ethernet (PoE). Another innovative
feature of the EDN312x is the built-in Central Office (CO)
base-band filter, available in both POTS (cost-effective
POTS, ETSI POTS, and ANSI POTS) and ISDN versions.
EDN312x is also available in a version with ISDN high
pass filter and no low pass filter. The integrated base­band filter enables base-band telephony.

IP DSLAM EDN312x allows bonding of up to six lines in
order to provide high bandwidth to end-users, even to
end-users located at distances above 1.6 km. Line
bonding is a technique that allows the use of several
physical twisted copper pairs as if they form one single
line, provided that this is also supported in the CPE.

The scalable IP DSLAM concept is built from a
combination of the 12-line IP DSLAMs and the Ethernet
Controller Nodes — with the possibility of using the 8­port switch ESN108 for aggregation in between.

The system can be configured in various ways:

• EDN144x:
144-line IP DSLAM built from one ECN330 and 12
EDN312x IP DSLAMs (link aggregated configuration
using both uplinks from the IP DSLAM)

• EDN288x:
288-line IP DSLAM built from one ECN330 and 24
EDN312x IP DSLAMs. For redundancy, the 288-line
IP DSLAM can be expanded with an additional
Ethernet Controller Node (ECN330), as shown below.

12-line IP DSLAM EDN312x with built-in base-band filter.

The front end of IP DSLAM EDN312x is well integrated
with standard building practice in the sense that it has
built-in Gas Discharge Tube (GDT) and Over Voltage
Protection (OVP), which means that the IP DSLAM can
operate as the primary protection.

Pre-configured solutions with EDN312

EDA 1200 is available as a pre-configured solution.
Ordered, delivered, installed, and commissioned as one
fully assembled unit, the system ensures easy and
trouble-free installation.

Solutions for fiber and Cat5

EFN324 is the cornerstone of Ericsson's fiber access
portfolio, targeting residential end-users, small
offices/home offices (SOHO), and small to medium
enterprises (SME).

EFN324 is a multi-functional, optical fiber access node
that supports triple play services, including multicast
video streaming with IGMP snooping.

EFN324 provides 24 x 100 Mbps Fast Ethernet downlink
ports and two combo GbE uplink ports. EFN324 is
prepared for 19” rack mounting.

EFN324 is available in three variants:

• Single mode single fiber (EFN324f)

• Multi mode dual fiber (EFN324df)

• Cat5 (EFN324c)

Controller Nodes and Ethernet
switches

The EDA solution offers a unique suite of 1st and 2nd
level Ethernet aggregation switches and Controller
Nodes. The Ethernet Controller Nodes are equipped
with EDA Management Proxy (EMP) for local
management of subtended nodes. The Ethernet
switches and Controller Nodes are all managed by the
Public Ethernet Manager (PEM), using the Ethernet
connection for both user traffic and management traffic.

The portfolio comprises the following products:

• ECN330; 24-port electrical Ethernet Controller Node
with two combo GbE uplinks and one electrical GbE
uplink. Includes standard switch functionality when
EMP is disabled.

• ESN212; 12 port Gigabit Ethernet switch with 8
electrical GbE ports and 4 SFP ports.

• ESN410; 12-port Gigabit Ethernet switch with 8 SFP
and 4 combo ports

• ESN108; 8-port electrical Ethernet switch with optical
uplink (FE/GbE)

ECN330 and ESN108 include integrated Power over
Ethernet (PoE) functionality for powering the connected
IP DSLAMs.

EFN324f with 24 optical ports

Combined with the Ethernet aggregation switch
ESN410, a large scale, cost-efficient fiber node is easily
built, supporting Single Mode/Single Fiber (SM/SF),
Multi Mode/Dual Fiber (MM/DF) and Cat5.

For installations, where the IP DSLAM is not connected
to a switch with built-in Power over Ethernet (PoE), a
separate Ethernet Power Node, (EPN210 or EPN102)
can be used, however, the VDSL2 IP DSLAM (EDN612)
may also be powered separately.

Ethernet Controller Node ECN330

The Ethernet Controller Node ECN330 is a combined
management and traffic aggregation nodes. On the
outside, the Ethernet Controller Node looks like an
ordinary Ethernet switch, however, as the name
indicates, it includes more functionality.

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 1

st

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.
