3.2.4 machine-oriented communication (MOC) device: A device involved in the support of
MOC applications.
NOTE – In the NGN environment, an MOC device connects with NGN directly or indirectly through an
MOC gateway.
3.2.5 machine-oriented communication (MOC) end user: An end user of MOC applications.
NOTE – This end user may be a system (e.g., MOC application server, other network equipment, other
applications, MOC device, MOC gateway), or a human (e.g., NGN end user).
3.2.6 machine-oriented communication (MOC) gateway: A gateway which interconnects and
provides interoperability between MOC local networks and the network, and where applicable,
interoperability at the MOC application level.

NOTE – In the NGN environment, an MOC gateway acts as a proxy or data aggregator to ensure
interoperability and interconnection of MOC devices with the NGN.

3.2.7 machine-oriented communication (MOC) group: A list of MOC devices and/or
gateways grouped according to one or multiple criteria.

NOTE – Criteria may include the MOC application subscriber, MOC device manufacturer, MOC
application, or location.
3.2.8 machine-oriented communication (MOC) local network: A network which provides
connectivity between MOC devices without the intermediation of an MOC gateway, and between
MOC devices and gateways.
NOTE – An MOC local network may provide IP based and/or non-IP based connectivity.

3.2.9 meter: A device that measures and optionally records the quantity, degree, or rate of
something, especially the amount of electricity, gas or water used.
NOTE – A meter is responsible for measuring the total amount of something consumed in a period.
