NEQ
Network Element Equivalence. NEQ calculations based on
Network Element (NE)
A network element is comprised of telecommunication equipment (or groups/parts of
telecommunication equipment) and support equipment that performs network element
functions. A Network Element has one or more standard Q-type interfaces. A network
element can be directly managed by a management system. See also Node.
Network Element Equivalent (NEE)
The functionality, database size and processing power that are required from the Lucent
OMS are different for each type of network element that is supported. Therefore each
type represents a certain amount of Network Element Equivalent.
Network Mediation Unit (NMU)
Collects fault and alarm events from transmission equipment. The Lucent OMS can
forward alarms to the NMU. The NMU can forward alarms to an Operations System.
Network Service Access Point (NSAP)
An end system address of the System Controller according to ISO 8348 AD2. The
format is ISO_DCC_LUCENT, which has the following structure:
NMC
Network Maintenance Center
NNE
Non-SDH network element
NNI
Network Node Interface
Node
A node or network element is defined as all equipment that is controlled by one system
controller.
Node
Defined as all equipment that is controlled by one system controller. A node can not
always be directly managed by a management system. See also network element.
NOMC
Network Operation Maintenance Channel
Non-revertive switching
In non-revertive switching, there is an active and standby high-speed line, circuit pack,
etc. When a protection switch occurs, the standby line, circuit pack, etc., is selected
causing the old standby line, circuit pack, etc., to be used for the new active line, circuit
pack, etc. The original active line, circuit pack, etc., becomes the standby line, circuit
pack, etc. This status remains in effect when the fault clears. Therefore, this protection
scheme is "non-revertive" in that there is no switch back to the original status in effect
before the fault occurred.
