MULTIMEDIA INTEGRATED DIGITAL ACCESS SYSTEM1. Introduction toMIDAS NMSMIDAS Overview1–2System Specifications1-9Using MIDAS1–9IntroductionThe intent of this section is to introduce the user with the MIDAS NMS terminology andthe general operating instructions for the MIDAS NMS.1. Prior to running the MIDAS Installation Program, ensure that allnecessary hardware configuration and interconnections have beencompleted, including the Software license key, in accordance with theMIDAS 4.X Software Installation Manual.2. Prior to running the MIDAS NMS, it is necessary to follow the InitialSystem Settings steps in Section 2, Setup and Operation.The Multimedia Integrated Digital Access System (MIDAS) is a sophisticatedpower and transponder bandwidth management system for digital satellitecommunication networks. The Network Management System (NMS), runningMIDAS software, Version 4.X, provides the signaling and control elementsfor the network, manages power, transponder bandwidth, and circuits on ademand basis. Together, MIDAS and the NMS manage and allocate satellitenetwork resources efficiently and cost effectively.The MIDAS software is distributed throughout the network with elementsresiding within each MIDAS 1000 series control channel modem, providingcost-effective scalability of the network. Portions of the MIDAS software alsoreside on the network controller and operator workstation, providingcentralized control of power and transponder bandwidth, and permittingenhanced features such as circuit priority and preemption.MIDAS 4.X NMS Configuration, Rev. 6Introduction to MIDAS NMS 1–1
MIDAS software provides a graphical user interface(GUI) for network management functions. UsingMIDAS, the operator configures, modifies, controls,and monitors the elements in the satellite network. Thesoftware provides: Graphical views of network statisticsInput and maintenance of database informationPassword-secured access to system functionsand dataMIDAS OverviewIt is helpful to understand the basic description of a MIDAS satellitecommunications network and the NMS before proceeding with theexplanation of the MIDAS operating instructions.MIDAS services include: Circuit RestoralHunt GroupsPriority Assignments and PreemptionBandwidth Pools (Public or Private Pools)Predefined Point-to-Point (P-P) and Point-to-Multipoint (PMP) BroadcastData and VideoOn-Demand PMP Symmetrical or Asymmetrical Return ChannelAssignmentsRemote Site Initiated CallsFull Mesh Circuit CapabilityNMS SiteThe NMS site hosts the combination of computers, printers, software, andsatellite modems responsible for managing the entire satellite communicationsnetwork.The NMS site could also have one or more traffic-carrying nodes sharing theRF equipment with the NMS. A node, if located with the NMS, stillcommunicates with the NMS over the satellite.MIDAS 4.X NMS Configuration , Rev. 61–2Introduction to MIDAS NMS
NMS ComponentsThe NMS consists of the following:Controller ServerThe NMS Server is a Pentium -based computer that also hosts the networkdatabase. The NMS server functions include: Network configuration maintenance (of both static and dynamicinformation)Bandwidth and power managementCircuit managementNetwork monitoring and controlAutomatic Frequency Control (AFC)The NMS Server also maintains an extensive log of all network events:Call detail records can beexported for offline billing. Call detail recordsAlarmsSystem eventsNMS ServerThe operator workstation is a Pentium desktop computer with the MicrosoftWindows NT operating system and the MIDAS software (the GUI).Remote NMS Workstations are available, as an option.Network Control ModemThe SNM-1001 Network Control Modem allows communication of callcontrol and network management messages with the remote nodes over thecontrol channels. The modem transmits on the outbound control channel to theremote nodes and receives the incoming messages from the remote nodes onthe inbound control channel.For detailed information on the network control modem, refer to theSNM-1001 Network Control Modem Operation and Maintenance Manual.LinkSync ModemThe SNM-1002 LinkSync Modem monitors the outbound control channelat the NMS site. The outbound control channel is used as the frequency andpower reference for LinkSync calculations.MIDAS 4.X NMS Configuration , Rev. 6Introduction to MIDAS NMS 1–3
LinkSync is a unique MIDAS feature that provides:Automatic Frequency Control (AFC)The AFC process compensates for earth station frequency drift due tohardware aging and/or other factors, reducing the frequency uncertainty forcontrol and traffic channels. This compensation allows for faster call setup andtighter carrier placement.Uplink Power Control (UPC) at the NMS siteThe UPC process dynamically adjusts the transmit power for the outboundcontrol channel, thereby allowing a constant power level to be received by thedownlink from the satellite. This adjustment makes it possible for theoutbound control channel to be used as a reference.Circuit DisruptionMIDAS supports a family of single-channel traffic nodes using combinedcontrol channel and traffic modems, such as the SNM-1010/1010L. Thesenodes communicate on the control channel when no data circuit is active, andreprogram themselves to become a traffic modem when the circuit is activated.In the event that the network, or the network operator, needs to terminate orpreempt a circuit between two of these nodes, the LinkSync modem is used togenerate a carrier that forces the two nodes to lose carrier lock. This circuitdisruption causes the two nodes to reprogram themselves as control channelmodems and resume communication with the NMS.MIDAS 4.X NMS Configuration , Rev. 61–4Introduction to MIDAS NMS
Standard ControllerServer FeaturesFeatures of the MIDAS Controller Server include: Network configuration and administration: Network monitoring and control Network data collection and processing Circuit setup, termination, and scheduling Call detail recording Printable logs and reportsBandwidth and power management: C-band or Ku-band operation Bandwidth and power allocation on demand Dedicated bandwidth pools Configurable channelization and carrier spacing LinkSync AFC and UPC Support 70/140 MHz and L-band modemsOptionsMIDAS options include the following:RedundancyLocally Redundant Controller Server with automatic switch-overRedundant Network Control ModemCircuit Power ManagementRedundant LinkSync ModemSite-level call blocking ensures that a node does not transmit at a powerlevel beyond the capacity of the RF Amplifier. The system blocks circuitsetup if the total utilized power exceeds the power (less backoff) of thepower amplifier at that site, resulting in improved system stability.For detailed information on the SNM-1002 LinkSync Modem, refer tothe SNM-1002 LinkSync Modem Operation and Maintenance Manual.MIDAS 4.X NMS Configuration , Rev. 6Introduction to MIDAS NMS 1–5
Controller ServerRedundancyIn an optional 1:1 redundant configuration, the backup Controller Servermonitors the active Controller Server and the RF chain.If a failure is detected in the active Controller Server or the RF chain, thebackup NMS assumes the active role. If required, the Controller Serveroperator can command a switchover manually.Active and backup Controller Server(s) synchronize the databases on the LANover a dedicated circuit.Optional 1:1 redundancy for the Network Control Modem or the LinkSync Modem is provided via Comtech EFData's SMS-301 Redundancy Switch.Within 20 milliseconds of a detection of a fault in the online modem, theSMS-301 switches to the backup modem.The SMS-301 switch must be configured as remote address 1 running at EIA232, 19.2 kbps. Modem A and Modem B must have remote addresses 2 and 3,respectively. Those modems must be configured at 9600 bit/s. (EIA-485, 2wire, Even). For detailed information on the SMS-301 switch, refer to theSMS-301 Redundancy Switch Installation and Operation Manual.MIDAS 4.X NMS Configuration , Rev. 61–6Introduction to MIDAS NMS
