Introduction TereScope Management Options MRV Communications, Inc. offers a variety of management options for the TereScope FSO product family. Whether you are a Network Service Provider, Cellular Network Operator, or a Private Enterprise, MRV can provide management options for your specific requirements. The various management scenarios supported include: SNMP, dry contact and remote TereScope status monitoring. In addition, MegaVisionWeb, MRV s NMS application, provides advanced management features, including customized GUI and alarm monitoring. TereScope 155 Protocol Independent Series Management for the TereScope1000, 1000x and 3000 systems can be performed using any of the following options: SNMP Access management Remote TereScope Monitoring Local Monitoring via PalmPilot or Laptop with monitoring software. SNMP Access Management This method provides remote in-band management for your TereScope over Ethernet networks. To support this management method, an SNMP Access box (See Figure 1: SNMP Access Box) is required. The SNMP Access box serves as an SNMP agent for the TereScope system and is rackmountable. The SNMP Access box interfaces with the TereScope systems through its SC optical ports to the TereScope fiber to RS-232 converter and converts the RS-232 data into SNMP MIB objects. MegaVision Web GUI displays these objects and supports SNMP-based monitoring and alarm configuration (See Figure 2: MegaVision TereScope monitoring). For added flexibility, these MIB objects can also be browsed using industry standard SNMP platforms such as HP OpenView. Figure 1: SNMP Access Box
Figure 2: MegaVision TereScope monitoring Figure 3: TereScope network management Connecting the TereScope to the SNMP Access box is simple. A TeleByte 271M/ST fiber transceiver is connected to the TereScope s RS-232 port to enable multimode transmit and receive fibers to be run to the SNMP Access box, where they are plugged into an SC interface. The SNMP box is then configured through an RS-232 port on the front of the box. The SNMP Access box interfaces with the user s network via an RJ-45 Ethernet connection (see Figures 4).
Figure 4: Network Interconnection for SNMP Management The SNMP Access device allows management of a number of TereScope system s parameters including RSSI strength, detector voltage, detector current, receive/transmit status, laser status, temperature, and run time. Alarms can also be set for a number of critical operational parameters. For a complete description of the MIB tree, refer to the SNMP Access operations manual. Remote TereScope Monitoring This option provides remote out-of-band management for the TereScope over RS-232 and BNC connections. To support this management option, the Remote TereScope Monitoring System (RTMS) is required. The system includes TereScope Monitor management software, which provides a GUI as well as a series of media converters that allow the user to remotely connect to the TereScope s RS-232 management and BNC video ports via fiber optic cabling. By transmitting signals over fiber, the risk of lightning damage to components at the customer s site is eliminated while security and greater transmission distance are gained. Operation Monitoring By accessing the RS-232 port of the TereScope unit, the user can enjoy the full benefit of the TereScope Monitor software management capability. The software s GUI (See Figure 5: TereScope Monitor Main Menu ) allows for direct monitoring of operational parameters including received signal strength, laser status, operating temperature, receive diode status, and other indicators
for specific units. For updated information on the specific functions offered, refer to the TereScope Monitor Manual. An option exists to generate a performance Log file. Once the testing phase is completed, the file is sent to MRV s support team for diagnostic and analysis. Figure 5: TereScope Monitor Main Menu Alignment Monitoring By accessing the BNC video port on TereScope, the user is able to directly observe the accuracy of the link alignment. The video port is fed by a camera focused on the TereScope s detector. When the two TereScope units are aligned correctly, the laser spot appears on the center of the detector (See Figure 6: Aligned TereScope and Misaligned TereScope). When RTMS is connected to the TereScope 3000 systems, users also have the option of switching to the unit s external camera. This view enables the user to verify rough alignment and determine if there are any obstructions in the line of sight. An external video monitor is required to view the output of RTMS.. Figure 6: Aligned TereScope and Misaligned TereScope
Local monitoring via PalmPilot This method provides portable graphical user interface that allows for monitoring of system parameters through a serial connection to the TereScope (see Figure 7: 3Com PalmPilot with Modem Cable). As a result, PalmPilot devices running PalmOS version 2.0 or higher, offer control of many TereScope functions. This option is highly beneficial to link installers, enabling simple and quick monitoring that require only a hand-held PalmPilot device. For a complete description of this functionality, refer to the TereScope Control for PalmPilot manual. Figure 7: 3Com PalmPilot with Modem Cable TereScope 1000 and 622 Series The TereScope 1000-622, 3000-622, 1000G and 3000G systems include their own integrated SNMP management cards. This card is accessible via RJ-45 or multimode fibers with SC connectors (see Figure 8 for view of connectors in TereScope card cage). The MIB tree for this device is similar to that of the SNMP Access box. The MegaVision Web GUI can display these objects enabling SNMP based monitoring and alarm configuration. TereScope 1000G and 3000G are also manageable via a simple command line interface via RS232 serial cable (remote login). For more information on the command structure, refer to the TereScope 1000 Series manual. Figure 8: Connectors in 1000G (left) and 3000G (right)
TereScope Mux, 2, 10, 25, and 155 PS series Management for these TereScope models can be performed using any of the following options: SNMP Management Remote TereScope Monitoring SNMP Management This option provides remote in-band management for TereScope over Ethernet networks. To support this feature, our optional management agent is required. By placing this factory set management card into the transceiver unit, remote SNMP monitoring of the link is provided. The management card has an RJ-45 connector interface (10BaseT only) to the network. Through this connector, the MegaVision Web management application provides full Web-based SNMP management of the TereScope link. The following management information is provided: 1- General Device parameters: (Product type, MAC, IP address): 2- Performance parameters: Wireless link On/Off (FSO data) Interface connection On/Off (data port) Received signal strength. (Laser signal) Temperature inside the unit (measured on the management board). Power On/Off Figure 4: MegaVision TereScope monitoring Dry Contact Our dry contact alarm is designed to relay vital link information back to a control station and instantly notify personnel in case of a link failure. Applications for the relay signal range from a simple LED or sound alarm to a more complex multi-activation system. The relay may interface with any one of the following:
1) A PC computer with a Data Acquisition Board with digital input. 2) A Programmable Logic Controller (PLC). 3) A Smart Internet-Enabled Appliance. For a complete description of the Dry contact technical features, refer to the Dry Contact application note. RSM Figure 5: Dry Contact front panel The RSM - Remote Status Monitor, is an option to remotely monitor a TereScope IR status, for Optical Access TereScope 2, 10, 25 and 155PS series (does not apply for TSx/A/XXX/XX or TSx/C2/XXX/XX). Serving as an out-band management option, the RSM in-door monitor (refer to Figure 9: Remote Status Monitor front panel) can be located more than 50 cable meters away from the transceiver s outdoor unit. Figure 9: Remote Status Monitor front panel The RSM includes the following indicators: * POWER (Unit ON/OFF). * AIR LINK FLAG. * F/O FLAG (link presence on the fiber or copper interface) * ALARM (low optical power received). * OPTICAL POWER RECEIVED Digital display used to report the strength of the optical power received at the air link receiver
Range 0000 1200 (relative reading display) Receiver threshold 20 (depended on the TereScope model) Receiver saturation 1100 (depended on the TereScope model). Reading is proportional to received / optical signal.
