1 Network Management System NMS June 17, 2007 Tapio Malmivaara 1

2 Network Management System Allows you to... - Manage - Monitor - Diagnose - Reconfigure... your SATELLINE modem networks remotely June 17, 2007 Tapio Malmivaara 2

3 Benefits of NMS Remote configuration... saves travel expenses and time Monitoring... enables to analyze trends in order to anticipate problems helps to pinpoint faults in network minimizes system down-time Online operation... keeps system statistics up-todate is non-intrusive to the June 17, 2007 Tapio Malmivaara 3

4 System Requirements Modems supporting NMS SATELLINE-3AS(d) NMS SATELLINE-3AS(d) Epic NMS (C) SATELLINE 3AS(d) VHF (C) NMS NMS NMS PC with Windows XP SATEL NMS PC Software Win XP NMS PC June 17, 2007 Tapio Malmivaara 4

5 How does it work? The master modem of the network is connected both to the user system and to a PC running SATEL NMS PC June 17, 2007 Tapio Malmivaara 5

6 How does it work? NMS does not disrupt normal operations of user application user data NMS data NMS master NMS substation June 17, 2007 Tapio Malmivaara 6

7 Online and Offline Online mode allows simultaneous operation of user system and NMS Master Repeater Offline mode allows rapid configuration and testing June 17, 2007 Tapio Malmivaara 7

8 Online user data NMS data Master Repeater June 17, 2007 Tapio Malmivaara 8

9 Offline user data NMS data Master Repeater June 17, 2007 Tapio Malmivaara 9

10 SATEL NMS PC software package - consists of three programs. SATEL NMS PC SETUP Network design Monitoring setup Alarm setup Design updates Creates a system file (.sax) Parameter upload to modems locally or remotely SATEL NMS PC MONITOR Network monitoring (offline/online) Generates local and remote alarms Reads the system file (.sax) SATEL Serial Server Background application Handles data communication between NMS PC and Master modem. Enables remote operation of NMS system over IP net June 17, 2007 Tapio Malmivaara 10

11 SATEL NMS PC SETUP / User interface View menu Network settings Design Modem parameter Comm log Monitoring settings Routing table Created by SW To-Do list Step-by-step quidance of the whole design procedure Task performed by clicking the item on the list The main setup view (acc. to menu selection) List of common network parameters Graphical designer for adding modems and links to the net Modem parameter chart (basic or advanced) Log list of communication between NMS PC SETUP and Master modem Monitoring and alarm settings June 17, 2007 Tapio Malmivaara 11

12 SETUP PARAMETERS of SATEL NMS radio modem network are divided into three different categories: A. Radio modem parameters that must be defined when placing an order (= key parameters needed for production process) B. Radio modem default settings (= parameters that will be set at the factory, but can be modified later without hardware changes) C. System specific parameters (= initial data needed for network design by SATEL NMS PC SETUP) June 17, 2007 Tapio Malmivaara 12

13 A. Radio modem parameters that must be defined when placing an order Tx frequency Rx frequency (by default equal to Tx freq.) Frequency tuning band (if differ from default being = Average of Tx and Rx frequencies ±1 MHz) Channel spacing June 17, 2007 Tapio Malmivaara 13

14 B. Radio modem default settings (example below: 3AS(d) NMS, ch.sp. 25 khz) 1 ) Radio Settings TX frequency: MHz / TX Power 1 W RX frequency: MHz / FEC OFF / RSSI Threshold -112 dbm / Error check OFF TX delay 0 ms / Sync interval default / RX delay 1 ms 2 ) Network Mode (Basic - RX priority)!!! 3 ) Serial Port 1 DATA / RS232 / 9600 bps / 8 bit data / None parity / 1 stop bit 4 ) Serial Port 2 NMS / RS232 / 9600 bps / 8 bit data / None parity / 1 stop bit 5 ) Handshaking CTS Clear To Send / CD RSSI threshold / RTS Ignored / Pause length 5 bytes 6 ) Additional Setup SL-commands OFF June 17, 2007 Tapio Malmivaara 14

15 C. System specific parameters Data communication protocol Station names Terminal addresses (= protocol addresses) Network topology June 17, 2007 Tapio Malmivaara 15
