Glossary
Multiplexer Section Termination (MST)
Function that generates the Multiplexer Section Overhead in the transmit direction and
terminates the Multiplexer Section Overhead in the receive direction.
Multiplexer Timing Source (MTS)
Function that provides the timing reference to the relevant component parts of the
multiplex equipment and represents the SDH network element clock.
Multiplexing
A procedure by which multiple lower order path layer signals are adapted into a higher
order path, or by which the multiple higher order path layer signals are adapted into a
multiplex section.

N NE
Network element. The NE 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.
NEF
Network element function
NEM
Network element manager
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 ITM-SC
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 ITM-SC 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:
Network Termination Unit (NTU)
The system that contains the STU-R function.
NMC
Network Maintenance Center
