EDN
Ethernet DSL Node comprises EDN110 and
EDN312.
EMP
Ethernet DSL Node
End-user
An end-user is a consumer of services in
the access network. The end-user is
physically connected to the network and is
uniquely identified in PEM. Services are
given to and removed from end-users.
Engineering
Engineering is typically also referred to as
Network Engineering. The work prior to the
network goes into operation. (Engineering is
not part of FCAPS).
Engineering includes: Network planning, (IP
addresses, usage and location of Domain
Servers), installation of equipment
(switches, IP DSLAMs, servers), initial
configuration of equipment (assigning IP
addresses, subnet, defining management
VLAN), "loading" equipment into the
management system.
Once the Engineering is done and the
equipment is ready to go into service,
Configuration Management will take over.
Engineering is executed by Network
Managers.
EPN
Ethernet Power Node
Erlang
Erlang is a unit of measurement for
telephony traffic. One Erlang corresponds to
one telephony connection.
Ethernet Access Node
The EAN is a logical node built on the
ECN320 switch with built-in EMP function.
To create a EAN a number of ESN108
switches and 10-lines or 12-lines IP DSLAM
are connected to the ECN320. The nodes
are embedded in the sense that all
management are done by the ECN320. The
EDN288 IP DSLAM is an example of an
EAN.
Ethernet Converter Node
Converter Node for Ethernet.
EDA
Official product name for the EDA product.
Ethernet Power Node
Power supply for Power over Ethernet
(PoE) devices comprises EPN124 and
EPN102.
EXN
Ethernet Converter Node
Fault Management
Fault Management (FM) covers the area of
viewing and handling alarms coming from
the PEM or the managed network. Also
logging, filtering and correlating alarms are
handled within this functional area.
FCAPS
The term covers different functional areas
within the discipline of network
management.
FE-E1
Fast Ethernet to E1 converter used for small
sites in for example a back-to-back
transmission solution.
Frame
The unit of data, transferred as an entity
through an Ethernet.
FTP
File Transfer Protocol
G.711
The voice codec standard normally used for
telephony in digital exchange equipment
within the switched circuit network.
H.323
A suite of protocols, standardized by ITU for
