1 Safety Precautions PLEASE READ THESE SAFETY PRECAUTIONS! RF Energy Health Hazard The radio equipment described in this guide uses radio frequency transmitters. Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard. Do not allow people to come closer than 119 cm (47.2) to the front of the antenna while the transmitter is operating.
User Reference and Installation Guide 1-2 Proper Disposal The manufacture of the equipment described herein has required the extraction and use of natural resources. Improper disposal may contaminate the environment and present a health risk due to the release of hazardous substances contained within. To avoid dissemination of these substances into our environment, and to lessen the demand on natural resources, we encourage you to use the appropriate recycling systems for disposal.

User Reference and Installation Guide 2-12 2.5 System Description The overall digital radio architecture consists of a single 1RU rack mount Software Defined Indoor UnitTM (SDIDUTM) with a cable connecting to an Outdoor Unit (ODU). The 4.9 GHz ODU is designed for use with an external antenna only. This SDIDUTM /ODU architecture is advantageous when compared to a single IDU with external mount antenna, since supporting a signal of 4.

User Reference and Installation Guide 2-14 The ODU RF Up/Down Converter card provides the interface to the antenna. The transmit section up-converts and amplifies the modulated Intermediate Frequency (IF) of 350 MHz from the IF Processor and provides additional filtering. The receive section down converts the received signal, provides additional filtering, and outputs an IF of 140 MHz to the IF Processor.
User Reference and Installation Guide 2-15 SDIDUTM interfaces with the ODU to receive and provide modulated transmit and receive waveforms. The SDIDUTM also provides the physical interface for the user payload and network management. In transmit mode, the Framer merges user payload with radio overhead-encapsulated network management data. This combined data stream is transmitted without any loss of user bandwidth.
User Reference and Installation Guide 2-16 Figure 2-5. Ring Configuration. SONET/SDH rings are inherently self-healing. Each ring has both an active path and a standby path. Network traffic normally uses the active path. Should one section of the ring fail, the network will switch to the standby path. Switchover occurs in seconds. There may be a brief delay in service, but no loss of payload, thus maintaining high levels of network availability.
User Reference and Installation Guide 2-17 Figure 2-6. Consecutive Point Network 2.7 2 + 0 (East-West) Configuration The SDIDUTM supports an east/west, or 2+0, configuration that allows a consecutive point architecture to be achieved with only a single 1 RU chassis at each location. In this configuration the SDIDUTM contains two modems supplies and may contain two power supplies. One modem is referred to as the west modem and the other as the east modem.
User Reference and Installation Guide Connected to east modem 2-18 Connected to west modem Connected to west modem Connected to west modem Connected to east modem Connected to east modem Connected to east modem Connected to west modem Figure 2-7. 2+0 (East-West) configuration. 2.8 1+1 Protection The MDS FOUR.9 Series supports 1+1 protection as an option for a critical link. In this configuration, protection is provided in a single 1 RU chassis.

In this mode, one ODU at each location transmits to both two ODUs at the other location. This mode does not require the extra bandwidth or interference protection of diversity mode. It provides hitless receive switching and hot standby.

Front Panel connections in 1 + 1 multi-hop repeater configuration 2.10 Data Interfaces The I/O card has 2x100BaseTX interfaces that can be configured as either primary payload, or secondary wayside channels. The Over-the-air channel has a data-bandwidth capacity that is set by the frequency-bandwidth, modulation, and coding. The data-bandwidth may be allocated to various I/O card interfaces, including 155.
User Reference and Installation Guide 2-22 power level than needed to maintain the link in clear weather. Because transmit power remains high when the weather clears, the level of system interference increases. Radios operating at high transmit power will interfere with other radios, even if the interfering source is miles away from the victim. High interference levels can degrade signal quality to the point that wireless radio links become unreliable and network availability suffers.

User Reference and Installation Guide 3-2 3.2 Notices CAUTION DO NOT OPERATE EXTERNAL ANTENNA ODU UNITS WITHOUT AN ANTENNA, ATTENUATOR, OR LOAD CONNECTED TO THE ANTENNA PORT. DAMAGE MAY OCCUR TO THE TRANSMITTER DUE TO EXCESSIVE REFLECTED RF ENERGY. ALWAYS ATTENUATE THE SIGNAL INTO THE RECEIVER ANTENNA PORT TO LESS THAN –20 dBm. THIS WILL PREVENT OVERLOAD AND POSSIBLE DAMAGE TO THE RECEIVER MODULE. WARNING HIGH VOLTAGE IS PRESENT INSIDE THE ODU and SDIDUTM WHEN THE UNIT IS PLUGGED IN.
User Reference and Installation Guide 3-3 3.4 PRE-INSTALLATION NOTES It may be useful to gain familiarity with the MDS FOUR.9 Series via back-to-back bench testing prior to final installation. We highly recommend installation of lightning protectors on the ODU/SDIDUTM Interconnect Cable to prevent line surges from damaging expensive components. Back-to-back bench testing prior to final installation is highly recommended in order to gain familiarity with the product.

Each step in the process is detailed in the following subparagraphs: • Ensure RF Safety compliance: Ensure that appropriate warning signs are properly placed and posted at the equipment site or access entry. For a complete list of warnings, refer the Safety Precautions listed at the beginning of this manual.
User Reference and Installation Guide 3-8 altogether. If trees or other 'soft' objects protrude into the Fresnel zone, they can attenuate (reduced the strength of) a passing signal. In short, the fact that you can see a location does not mean that you can establish a quality radio link to that location. Microwave Data Systems provides a link planner spreadsheet that calculates the Fresnel ratio and helps determine link feasibility.
User Reference and Installation Guide 3-9 • Transmit Output Power: Selectable between +5 to +23dB in 1 dB steps. • Receive Antenna Gain: Enter the gain of the external antenna if used. • Link Distance: Enter distance in miles or kilometers (must select the correct units: miles or kilometers) • Fresnel Clearance Ratio: This is a factor indicating the radio line of sight. A clear radio line of site has a fresnel clearance ratio of +0.60.

User Reference and Installation Guide 3-12 Select the Grounding Location for both the MDS FOUR.9 Series ODU and SDIDUTM: The MDS FOUR.9 Series must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires - Grounding all ODUs as specified by supplier - Grounding all SDIDUTM to the rack. • Confirm the Presence of DC Power for the MDS FOUR.9 Series SDIDUTM.
User Reference and Installation Guide 3.6.3.3 3-13 Availability Calculation Availability of the microwave path is a prediction of the percent of time that the link will operate without producing an excessive BER due to multipath fading.
User Reference and Installation Guide 3-14 When designing multi-radio configurations, antenna size, antenna polarization, and antenna location are critical. The frequency plan must be selected based on desired data rate and expected link conditions. In a high interference environment or with lower gain antennas, higher bandwidth, more robust modulation formats must be employed. The available frequency plans are illustrated in Figure 3-3.
User Reference and Installation Guide 3-15 2. Determine the length of cable required. Allow three extra feet on each end to allow for strain relief, as well as any bends and turns. 3.6.6 ODU Transmit Power Setup Setting the ODU transmit power is conditional on the band and application. The installer of this equipment is responsible for proper selection of allowable power settings.
User Reference and Installation Guide 3-16 For mode 100FE1 (single channel configuration with 30MHz emission bandwidth) the power would be lowered from Tx Power – Antenna Gain Difference = Tx Power (External Ant) +5 dBm – 14.6 dB = -9.6 dBm (-10 dBm). Table 3-1 also presents transmit power settings for various antenna dish sizes. For link budget, EIRP(Avg) dBm = 37 dBi + Tx Power Setting (dBm). Table 3-2.
