2 Introduction to the Nodes

EDN312, EXN104, ESN108 and EPN102 are the nodes that make EDA

able to offer very flexible, as well as high volume cost efficient broadband

solutions. These nodes can be combined in different ways and with other

EDA nodes to create a specific solution.

2.1 EDN312

The EDN312 is a small, cost-efficient, 12-

port IP DSLAM designed for the EDA

solution. It aggregates 12 ADSL lines to

one or two 100 Mbps Ethernet and offers

aggregation both as bridge mode or

routed encapsulation mode.

The IP DSLAM can be used with the EDA subrack solutions and outdoor

cabinet. Management wise it can be managed as a part of an Ethernet

Access Node (EAN) or as a stand-alone node with the PEM management

system.

EDN312 is powered over the Ethernet cable. Power, End-user data and

management traffic run in the same Ethernet cable. EDN312x versions,

which include two Ethernet uplink connections, can be used for power

redundancy, uplink redundancy (RSTP), or link aggregation

EDN312xs versions are cost effective nodes with one Ethernet uplink and

no line LEDs (see section 4.2 on page 33 for more information about line

LEDs).

Subscriber legacy POTS connection to the local exchange is not changed

by the IP DSLAM, which means that telephony service can still be provided

to the subscribers in addition to ADSL.

The IP DSLAM is also fully suitable as a highly scalable standard DSLAM

where each block is a stand-alone node that aggregates 12 ADSL lines into

a standard Ethernet switch instead of a special designed box with back

plane. It is mounted on KRONE PROFILE rod mounting system (KRONE

LSA-PLUS EC 25).

The IP DSLAM is fully managed through SNMP. Most of the management

including line provisioning can also be done locally by using the ECN330

LCT.
