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 all-
in-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.
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.
