User Reference and Installation Manual 2-10 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) with an external antenna. The ODU is available with an integrated antenna or connectors to support an external antenna. Two ODU types are available servicing the 5.8 GHz band or the 5.3 GHz band.

User Reference and Installation Manual 2-12 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 Manual 2-13 The 64-QAM Modem performs the modulation and demodulation of the payload/wayside/SNMP data and forward error correction using advanced modulation and coding techniques. Using alldigital processing, the 64-QAM Modem uses robust modulation and forward error correction coding to minimize the number of bit errors and optimize the radio and network performance.
User Reference and Installation Manual 2-14 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 Manual 2-15 Figure 2-6. Consecutive Point Network 2.7 Network Management All of the MDS 5800 II parameters are accessible in three ways: 1. Using a standard web-browser via HTTP top access the built in webserver. 2. Via SNMP using the fully featured MIB, allowing for automation of data collection and network management. 3. Via a command line client accessible from a terminal client connected to the serial port, or telnet over the NMS Ethernet.
User Reference and Installation Manual • 2-16 Network Management options described in Section 2.9. 2.8 Power Management RF power management is a radio design feature that controls the power level (typically expressed in dBm) of the RF signal received from a transmitter by a receiver. The traditional goal of power management is to ensure that the RF signal at a receiver is strong enough to maintain the radio link under changing weather and link conditions.
User Reference and Installation Manual 2-17 2.9 MDS 5800 II Software and Network Management All of the MDS 5800 II parameters are accessible through a Graphical User Interface (GUI) installed on every SDIDUTM. To access this the SDIDUTM needs to be connected to a computer with a web browser installed. Directing the browser to the IP address of the SDIDUTM will start the GUI. More information about the GUI is available in the User Interface Manual. 2.

User Reference and Installation Manual 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 Manual 3-12 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 and Figure 3-4. Additional frequency plans are available for co-existence with other 5.8GHz equipment or for backhaul purposes.

User Reference and Installation Manual 3-14 Larger antennas have the advantage of providing narrower beamwidths and high isotropic gain, which yields better link performance (higher fade margin, better availability), and improves immunity to spatial interference (due to the smaller beamwidths). However, larger antennas are more costly to purchase and install than smaller antennas and in some cases, they require special equipment for installation due to narrower beamwidths.

This flexibility ensures compatibility with most rack mounting arrangements. Figure 3-6. MDS 5800 II SDIDUTM Dimensions 3.6.2 Installing the MDS 5800 II ODU The MDS 5800 II ODU is intended for mounting on either a pole or antenna mast. Each site must be assessed for the mounting method, location, and height.
User Reference and Installation Manual 3-19 Figure 3-7. Mounting Parts for the MDS 5800 II ODU 1. Remove the pole mount portion of the tilt bracket from the ODU by loosening the middle bolts and removing the top and bottom bolts on each side. 2. Mount the tilt bracket to the mounting pole using the U-Bolts and nuts. Insert the U-bolts around the pole and through the holes in the tilt bracket. Install a washer and nut to each side of the threaded U-bolt and hand tighten.

Select where the cable will enter the building from outside. 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. Route the cable.
User Reference and Installation Manual 3-21 The SDIDUTM is equipped with TNC female connector on the front of the chassis. Depending on the ODU type, it will be equipped with either a N-type or TNC female connector at its interconnecting port. A length of coaxial cable (such as Times Microwave Systems LMR-400, LMR-300 or LMR-200) fitted with the appropriate N-type or TNC male connectors is required to connect the ODU to the SDIDUTM.
User Reference and Installation Manual 3.6.4.1 3-22 Grounding the ODU 1. Place the grounding rod so as to allow for the shortest possible path from the grounding cable to the ODU. 2. Drive the grounding rod into the ground at least eight inches from the ground surface. 3. Attach a grounding clamp to the grounding rod. You will use this clamp to attach grounding wires for both the ODU and indoor junction box, reference Figure 3-11. Figure 3-11 Ground Connections to ODU 4.
User Reference and Installation Manual 3.6.4.2 3-23 Grounding the SDIDUTM 1. Remove the nut and ring lug terminal from the SDIDUTM optional Chassis GND stud (located on the front panel). 2. The provided ring lug crimp terminal is intended to be used with 18 AWG wire (provided by the customer). The SDIDUTM should be able to be connected to a system or building electrical ground point (rack ground or power third-wire ground) with a cable of 36” or less. 3.
User Reference and Installation Manual 3-24 installed and properly grounded. If this is not the case, the same measurement can be made between cable pin 1 (RET) and a convenient ground (such as an ac outlet third-wire ground). 5. Turn the -48 V dc supply off. 6. Plug the SDIDUTM power cable into the SDIDUTM front panel DC Power connector (DC Input). Place the voltmeter probes on the cable connector screw terminal screw heads as per step 2 above. Refer to Figure 3-12.
User Reference and Installation Manual 3-25 3.7 MDS 5800 II Quick Start Guide Configuration of the MDS 5800 II SDIDUTM does not require a connection to the ODU. It is suggested to configure the SDIDUTM prior to connecting to the ODU. Each SDIDU has a Graphical User Interface (IDU) installed that can be accessed through a computer connection. The GUI is described in detail in the XXXX manual. The section below describes how to get started configuring the SDIDU TM via the GUI. 3.7.
User Reference and Installation Manual 3-26 3.7.3 Connecting the SDIDUTM to the PC and Power Source Perform the following steps to ensure the SDIDUTM is powered up and connected to you PC: 1. To connect to the SDIDUTM DC power connector (located on the left front SDIDUTM panel), an SDIDUTM power cable is required. A mating power cable connector (Phoenix Contact P/N 17 86 83 1) is provided with the MDS 5800 II SDIDUTM for construction of this cable.
User Reference and Installation Manual 3-27 9. Connect the SDIDUTM to the laptop computer, using a Cat-5 Ethernet cable or connect the SDIDUTM to a computer network, using a Cat-5 Ethernet cable.
