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 base-
band 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 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.
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 8-
port 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.
