A type of Ethernet service that is based on a multipoint-to-multipoint EVC (Ethernet
virtual connection).
electrical potentials caused by direct contact or induced by an electrostatic field.
A type of Ethernet service that is based on a point-to-point EVC (Ethernet virtual
connection).
A logical channel that uses a data communications channel (DCC) as its physical layer,
to enable transmission of operation, administration, and maintenance (OAM)
information between NEs.
Element Management System
A technology for layered protocols, in which a lower-level protocol accepts a message
from a higher-level protocol and places it in the data portion of the lower-level frame.
Protocol A's packets have complete header information, and are carried by protocol B
as data. Packets that encapsulate protocol A have a B header, an A header, followed by
the information that protocol A is carrying. Note that A could equal to B, as in IP inside
IP.
A path protocol which connects the host with various control units in a storage system.
It is a serial bit stream transmission protocol. The transmission rate is 200 Mbit/s.
A part, device, subsystem, functional unit, equipment, or system that can be considered
individually.

A LAN technology that uses Carrier Sense Multiple Access/Collision Detection. The
speed of an Ethernet interface can be 10 Mbit/s, 100 Mbit/s, 1000 Mbit/s or 10000 Mbit/
s. An Ethernet network features high reliability and is easy to maintain.

configured threshold. If the value exceeds the threshold, an event is reported.
A type of boards. EoD boards bridge the PSN and TDM networks, enabling Ethernet
service transmission across PSN and TDM networks.
A type of Ethernet service provided by SDH, PDH, ATM, or MPLS networks. This
service is carried over a dedicated bridge and point-to-multipoint connections.
