In this way, there is only one management interface and
one static IP address. For provisioning, the EMP is
managed via standard MIBs, and for system
maintenance via EDA SNMP MIBs. All SW images and
configurations are stored in local non-volatile memory to
secure full operation, even if access to the management
system is unavailable.
EMP secures a fast and safe installation process and
low recovery time in case of a total power outage,
returning the network into operation within a few
seconds after the power has returned.
EDA Topologies
EDA 1200 support a number of topologies below the
Ethernet Controller Node ECN330.
ECN330 EMP supports the “EDA legacy topologies”
including ESN108-based scenarios, EXN104 and switch
extension, as well as the ESN212 and EDN612 are
supported for VDSL2 deployment.
In order to increase the uplink capacity for VDSL2, one
or more ESN410 may be used for traffic aggregation for
the VDSL2 nodes. Typically a VDSL2 node will be
remote a cabinet consisting of an ESN212 and
EDN612/EDN312 IP DSLAMs.
Flexible topology
Ethernet Controller Node ECN330 also supports flexible
topologies together with ESN212, which allows
unmanaged — or even 3
rd party — switches between the
EMP and the ESN212 aggregation switch.
The flexible topology support is particularly powerful for
VDSL2 deployment in scenarios where telecom
operators already have access aggregation switches in
place, with non-Ericsson equipment.
L2CP BRAS controlled provisioning
Using the L2CP protocol makes it possible for an
operator to use a management system independent of
PEM. The nodes that can be accessed are the
Controller Nodes ECN330.
Disabling EMP on port basis
By disabling EMP on a specific port on ECN330, makes
it possible to add third party equipment such as alarm
boxes in the same Ethernet connection.
SNMPv2 and SNMPv3
All EDA elements support SNMPv2 for provisioning,
monitoring and traps sending. For obtaining security in
the network all management commands are
encapsulated in a management VLAN securing
unauthorized access to any element in the EDA
network.
SNMPv3 is implemented in ECN330 adding an
additional element of security to the VLAN security.
Adding SNMPv3 to the management an even more
secure connection can be established, e.g. if
management is done over a third party network.
Local Craft Tool
A Local Craft Tool (LCT) is partly built-in the ECN330
Controller Node, making it possible to use a standard
laptop as tool.
The LCT is used for:
• Installation of software images on ECN330
• Line Test; testing and line training on all ADSL lines
• Provisioning of end-users using scripts
