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.
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 300 019-
1-3 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 road-
side 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.
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.

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.
