sat-nms Network Management Systems NMS


SatService Network Management System is a comprehensive software-based system providing monitoring and control of SCPC/MCPC VSAT stations and in general Satellite Ground Stations from a central site. The system consists of two parts:

nms

VSAT Local Controller VLC

The VSAT Local Controller (VLC) monitors and controls the equipment of a site. It is similar to the sat-nms M&C system without a graphical user interface onsite and with some extensions to operate unattended and to send event messages to the central NMS. The VLC has full control of all the parameters of the connected equipment.

The monitoring is performed locally without any influence and connection to the NMS. The equipment is polled and monitored continuously. If an alarm is detected, like summary alarm, lock alarm, thresholds or limits of data quality, this alarm is sent to the NMS and is stored in a central data base. The operators is alerted via a graphical and an audible alarm. The operator monitors the status of the equipment via the NMS screen and can dial into the station.

Network Management System NMS

The NMS allows the central management of multiple VLC's on differents sites and provides the communication facilities to connect these sites. The connection can be made of any kind of TCP/IP connection (LAN or dialup via Modem, ISDN, etc.).

The operator screens are the same as of a M&C system, the NMS provides the same functionality as a M&C system, the only difference is that it provides the framework to handle a lot of stations from one site and manage all the data and events within one event log taking into account the data of all stations. The NMS operator can store also complete equipment configurations and generate PRESETS, which are equipment and not station dependent, so the operator can copy presets from one station to another and so save a lot of configuration time if the equipment or station set-up is common or comparable.

Key Features

Hardware VLC

vlc front view

The VLC could be equiped with a local user interface (monitor, keyboard, trackball) like the MNC System for local control. up

Interfaces to Satcom equipment

The VLC is able to monitor and control the attached equipment through the following types of interfaces:

sat-nms Drivers

The Universal Device Driver concept reduces the cost for the configuration of new drivers. The user can configure its own drivers without writing software. Parallel to that SatService will always provide the service to adapt new equipment with drivers to the system. Drivers are always the same for M&C and VLC systems.

The Driver Development Kit (DDK) which is a Eclipse-Plattform based Integrated Development Environment Entwicklungsumgebung support the user to configure and test new drivers and protocols. For details please read the data sheet(pdf) . A Reference document about the sat-nms Driver- und Protocol syntax ist available here. up

NMS Client

device

The Client Software is the User Interface for the operator of the network and all sites. The operator accesses the system normally from a Clinet PC connected with the NMS via TCP/IP. The number of clients is not limited.

The plattform independend Java Software requires only a Java Virtual Machine on the Client-PC. We have tested the software successfully on Windows 9x/NT4/W2K/XP and of course on Linux PCs.

With the purchase of the sat-nms Network Management System do you obtain the licences for a unlimited number of clients so that you do not have additional cost.

There are two kinds of user interface available:

task

The Device oriented User Interface provides all parameters of the satellite ground station equipment and a deep insight in the equipment for system engineers. It is part of the delivery and shows every attached device in a block diagram view. The device oriented sceen will mostly be used in stations with a static configuration for monitoring & control and redundancy switching.

The Task Oriented User interface is a customized User Interface, fully configurable and reduces the user interface to the special requirements of the operators. Several task oriented and or Device oriented User Interfaces can be used in parallel. SatService will be glad to offers you the configuration regarding you needs, but you are also able to do this by you own with the integrated graphical screen editor. up

Remote Access

The NMS server is completely remote configurable and maintainable. This requires only a TCP/IP connection. Also the Clients requires only a TCP/IP Verbindung to the NMS Server. This could be a already existing network (LAN) or a dialup connection (e.g. PPP).

SatService offers also ISDN and VPN solutions to connect different location on request. Via these routers SatService can give you remote support if you need it. up

Link Management Module

On top of the normal NMS functionality the sat-nms system can provide as option a Traffic and Link Management package which allows the operator to set-up and manage complete links either operator driven or scheduled automatically by time.

Satellite Control Channel

The new SCC (satellite control channel) option enhances the sat-nms system with the capability to control remote ground terminals or VSAT's via satellite, without the need of a terrestrial communication link. This enables the customer to set-up a small or medium sized VSAT system with the cost efficient NMS from SatService and to monitor&control equipment of different vendors (like transceivers, satellite modems and router etc.) at the remote station.
