Moscad Nfm System - Motorola MOSCAD 68P02958C00-B User Manual

MOSCAD NFM System

A typical network management system can be divided into three main levels:
Network Management Level
Element Manager Level
Element Level
The following section provides a brief description of the MOSCAD NFM components that
allow managing and supporting these network management levels.
Figure 2-6 shows a typical MOSCAD NFM configuration including all network management
levels. It describes the MOSCAD NFM architecture that includes NMC computers and
workstations that monitor and control - via the IP Gateway and the NFM RTUs - non-SNMP
devices at the communication sites.
In this configuration, the end devices at the communication sites serve as a NE (Network
Element) and the NFM RTU serves as an Element Manager that monitors and controls multi-
communication and environmental devices at the site. The IP Gateway allows monitoring and
controlling devices - via the NFM RTU - that are installed at multiple communication sites.
The NMC allows monitoring and controlling of all devices in the network via multiple IP
Gateways.
The NMC application can use the SNMP protocol and the IP Gateway MIB to Auto-discover
the IP Gateway, the communication sites as well as the devices and their objects.
By using this MIB, the NMC application can poll the devices and their objects (NEs and their
objects) in order to refresh its database and to display unsolicited events (Traps ) in the Alarm
Manager application. By using the TELNET application in the host, the operator can access
via the IP Gateway and the NM RTU any communication devices that have an RS-232 port
with interactive interface.
The MOSCAD NFM product can be integrated either with the Motorola PRN (Private Radio
Network) architecture or with a third party communication/telecommunication system via an
IP Gateway that gives the NMC applications access to the equipment and environmental
devices at the sites.
