2.2 Introduction

The Microwave Data Systems family of digital radios provides high capacity transmission, flexibility, features, and convenience for wireless digital communications networks. The Microwave Data Systems digital point-to-point radios represent a new microwave architecture that is designed to address universal applications for both PDH and SDH platforms. This advanced technology platform is designed to provide the flexibility to customers for their current and future network needs.

The Microwave Data Systems radio family is based upon a common platform to support a wide range of network interfaces and configurations. It supports links for 16 x E1/T1, 100BaseTX Ethernet, and DS-3/E-3/STS-1 (optional, consult factory for availability). The radio family is spectrum and data rate scalable, enabling service providers or organizations to trade-off system gain with spectral efficiency and channel availability for optimal network connectivity. The Microwave Data Systems digital radio family enables network operators (mobile and private), government and access service provides to offer a portfolio of secure, scalable wireless applications for data, video, and Voice over IP (VoIP).

The MDS FIVE Series digital radio family operates in the Industrial, Scientific, and Medical (ISM) band of 5.725 to 5.850 GHz, which is generically referred to as 5.8 GHz, and the Unlicensed National Information Infrastructure (U-NII) band of 5.25 to 5.35 GHz, which is generically referred to as 5.3 GHz. The MDS FIVE Series supports three types of user data payload connectivity:

• 100Base-TX intelligent bridging between two locations without the delay and expense of installing cable or traditional microwave.

• Scalable Ethernet capability of 25 and 50 Mbps is included. These scalable radios provide LAN connectivity and offer performance trade-offs between operational bandwidths, data rates, and distance.

05-4498A01, Rev. G

User Reference and Installation Guide 2-2

• 16E1 or T1 for cellular backhaul, enterprise voice applications and voice network redundancy

For customers such as cellular carriers requiring backhaul and backbone extension as well

as service providers requiring network redundancy, new Points of Presence (POPs), and last mile access, the MDS FIVE Series radio is a cost effective alternative to leased lines with carrier-class quality of performance. The MDS FIVE Series is a cost effective solution to meet the growing demand for enterprise Local Area Network (LAN) connectivity between buildings and campuses as well as service providers requiring reliable products for infrastructure expansion, extending Metropolitan Area Network (MAN) fiber access, and network redundancy.

The MDS FIVE Series includes integrated Network Management functionality and design features enabling simple commissioning when the radio network is initially set up in the field at the customer’s premises. Furthermore, a highlight of MDS radio products is scalability and the capability to support a ring-type architecture. This ring or consecutive point radio architecture is self-healing in the event of an outage in the link and automatically re-routes data traffic, thereby ensuring that service to the end user is not interrupted.

TM

The MDS FIVE Series is composed of a Software Defined Indoor Unit

(SDIDUTM) and Outdoor Unit (ODU). It supports 1+0 and 1+1 protection and ring architectures in a single 1 RU chassis. The modem and power supply functions are supported using easily replaceable plug-in modules. An additional feature of the SDIDU

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. The 64-QAM Modem performs the modulation and demodulation of the payload and forward error correction using advanced modulation and coding techniques. Using all-digital 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. The 64-QAM Modem also scrambles, descrambles and interleaves/deinterleaves the data stream in accordance with Intelsat standards to ensure modulation efficiency and resilience to sustained burst errors. The modulation will vary by application, data rate, and frequency spectrum. The highest order modulation mode supported is 64 Quadrature Amplitude Modulation (QAM).

The major functions of the SDIDUTM can be summarized as follows:

TM

• I/O Processing – The SDIDU

comes with a standard I/O capability that includes support for up to 16xT1/E1 and 2x100Base-TX user payloads, 2x100Base-TX for SNMP, and voice orderwire. In addition, option cards for DS-3/E3/STS-1, 1-2 x STM-1/OC-3, and 4xDS-3/E3/STS-1 may be added. The SDIDU

TM

architecture is flexible and allows for the addition of other I/O types in the

future.

TM

• Switch/Framing – The SDIDU

includes an Ethernet Switch and a proprietary Framer that are designed to support 1+1 protection switching, ring architecture routing, and overall network control functions.

TM

• Network Processor – The SDIDU

includes a Network Processor that performs SNMP and

Network Management functions.

TM

• Modem/IF – The SDIDU

Modem performs forward-error-correction (FEC) encoding, PSK/QAM modulation and demodulation, equalization, and FEC decoding functions. The IF chain provides a 350 MHz carrier, receives 140 a MHz carrier, processes OOK telemetry, and provides –48V power. Two modems can be used for 1+1 protection or ring architectures.

TM

• Power Supply – The SDIDU

power supply accepts -48 Vdc and supplies the SDIDUTM and ODU

with power. A second redundant power supply may be added as an optional module.

The Modem Processor and its associated RAM, ROM, and peripherals control the digital and analog Modem operation. It also provides configuration and control for both the IF and I/O cards.

The

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. In the receive mode, the Framer separates the combined data stream received from the 64-QAM Modem. The SDIDU 100BaseT data interface port. The SDIDU

provides network management data on 10 Mbps ports accessible via the 10/100BaseTX port. The Central Processor Unit (CPU) provides the embedded control and network element functionality of the NMS. The CPU also communicates with other functions within the SDIDU

TM

for configuration, control, and status monitoring.

In Ethernet models, the payload of each user Ethernet data packet and all T1 can be encrypted using an AES encryption algorithm. In addition, the encryption engine is re-seeded with a new, randomly generated key stream every 10 seconds, in order to provide enhanced security. The initial key is based off of a pass phrase entered into each MDS FIVE Series unit by the network administrator. Consult factory for the availability of this encryption function.

The power supply converts -48 Vdc to the DC voltage levels required by each component in the system.

2.6 Consecutive Point Architecture

The consecutive point network architecture is based upon the proven SONET/SDH ring. Telecommunications service providers traditionally use the SONET/SDH ring architecture to implement their access networks. A typical SONET/SDH network consists of the service provider’s Point of Presence (POP) site and several customer sites with fiber optic cables connecting these sites in a ring configuration (see deliver high bandwidth with high availability to their customers.

Figure 2-5). This architecture lets providers

05-4498A01, Rev. G

User Reference and Installation Guide 2-15

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.

The consecutive point architecture implemented in the MDS FIVE Series Digital Radio family is based on a point-to-point-to-point topology that mimics fiber rings, with broadband wireless links replacing in-ground fiber cable. A typical consecutive point network consists of a POP and several customer sites connected using MDS FIVE Series units. These units are typically in a building in an east/west configuration. Using east/west configurations, each unit installed at a customer site is logically connected to two other units via an over-the-air radio frequency (RF) link to a unit at an adjacent site.

Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and in-building connections is repeated at each site until all buildings in the network are connected in a ring as shown in need to be jumpered between two SDIDU there is a single SDIDU

2.8 Spanning Tree Protocol (STP)

Spanning Tree Protocol STP keeps Ethernet loops from forming in a ring architecture. Without STP, loops would flood a network with packets. STP prevents loops by creating an artificial network break. In the event of a network outage, STP automatically removes the artificial break, restoring connectivity.

2.9 1+1 Protection

The MDS FIVE Series supports 1+1 protection as an option for a critical link. In this configuration, protection is provided in a single 1 RU chassis. The SDIDU supplies and two modems. The power supply, ODU, IF/telemetry and modem are protected. The digital framing and LIUs are not. One modem is referred to as the west modem and the other as the east modem. 1+1 protection can be run in two modes called Protected Non-Diversity and Protected Diversity. © 2006 Microwave Data Systems Inc.

2.11 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 155.52 Mbps for STM-1, 2 Mbps per E1, up to 100 Mbps Ethernet, and up to 1 Mbps NMS. Only up to 100 Mbps of data-bandwidth may be allocated for either net data, and the two I/O card 100BaseTX interfaces will share that 100 Mbps databandwidth.

There is also an option mini-I/O card, which provides STM-1 Optical/OC-3 or STM-1 Electrical interfaces. The optical interface is single mode at 1300 nm. Consult factory for availability of Mini-IO STM-1/OC-3 Module.

2.12 Crosspoint Switch

The SDIDU™ crosspoint switch provides any-to-any E1/T1 routing between front panel ports and RF links, as shown in routings or custom routing. Custom routings are uploaded to the SDIDU™ via FTP. Two examples of the crosspoint capability are to use the crosspoint switch to configure a repeater or an add/drop. These examples are shown in Crosspoint Switch is used as a passthrough to send E1/T1s from the east modem to the west modem. In the add/drop example, the crosspoint switch connects E1/T1s from the modems to the front-panel ports.

2.13 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.

05-4498A01, Rev. G

User Reference and Installation Guide 2-23

Traditional power management techniques such as Constant Transmit Power Control (CTPC) and Automatic Transmit Power Control (ATPC) transmit at a high power level to overcome the effects of fading and interference. However, these techniques continue to operate at a higher 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. The traditional solution to system interference is to increase the distance between radios. However, the resulting sparse deployment model is inappropriate for metropolitan areas.

In response to the need for a high-density deployment model t he MDS FIVE Series use a unique power control technique called A minimum power level necessary to maintain a link regardless of the prevailing weather and interference conditions. The MDS FIVE Series is designed and manufactured to not exceed the +30 dBm maximum power allowed. The purpose of power management is to minimize transmit power level when lower power levels are sufficient. A management by controlling not only the power (dBm) of the RF signal, but its quality (signal-tonoise ratio) as well.

Minimal transmit power reduces potential for co-channel and adjacent channel interference with other RF devices in the service area, thereby ensuring maximum frequency re-use.

2.14.1 IP Address

Each SDIDU™ is configured independently for network parameters such as IP address, subnet, and gateway. However, the SDIDU™ also supports acting as a DHCP client, in which case the IP address can be assigned to the SDIDU™ using a DHCP server. A specific IP address may be associated with a particular SDIDU™ by configuring the DHCP server to server IP address based upon the SDIDU™ Ethernet MAC address.

2.14.2 Network

The SDIDU™ uses an “Out-of-Band” NMS network which is separated from the payload Ethernet network. Each SDIDU™ contains a managed Layer 2 Ethernet switch that supports SpanningTree Protocol (STP) for managing NMS traffic. This allows the SDIDU™ to be configured in a protected ring configuration where the STP will prevent an Ethernet loop in the ring. This will alow allow the ring to re-configure in the event of an outage. The SDIDU acts as a network bridge via the Ethernet switch and STP. The SDIDU™ does not currently support NMS routing capability.

2.14.3 NMS Network Operational Principles

The SDIDU™ does not provide routing capability. Therefore, all SDIDUs™ must be on the same subnet as the PC being used to access the SDIDUs™. If the SDIDUs™ and/or the PC are on different subnets, a router must be used, with the gateway addresses set appropriately.

shows the PC and both SDIDUs™ in the same subnet. In this case, no router is required.

3.6 Site Evaluation

A site evaluation consists of a series of procedures for gathering specific information about potential MDS FIVE Series locations. This information is critical to the successful design and deployment of a network.

Site evaluations are required to confirm whether or not a building meets network design requirements. The main objectives are as follows:

05-4498A01, Rev. G

User Reference and Installation Guide 3-6

• Confirm

• Line of sight for each link

• MDS FIVE Series ODU mounting locations

• Site equipment locations

• Cable routes

• Any other potential RF sources

• Prepare site drawings and record site information

3.6.1 Preparing for a Site Evaluation

The following tools are required to perform a site evaluation:

• RF and network design diagrams (as required)

• Binoculars

• Global positioning system (GPS) or range finder

• Compass

• Measuring tape and/or wheel

• Digital camera

• Area map

• Aerial photograph (if available)

• List of potential installation sites (“targeted buildings”)

The following tasks must be completed prior to performing a site evaluation:

• Prepare the initial network design by performing the following:

• Identify potential buildings by identifying targeted customers (applicable if you’re a service

provider)

• Identify potential links by selecting buildings based on the high probability of line of sight

• Arrange for access with the facility personnel into the buildings, equipment rooms, and

architectural plans to become familiar with the location of all ducts, risers, etc.

05-4498A01, Rev. G

User Reference and Installation Guide 3-7

3.6.2 Site Evaluation Process

The following steps must be completed to perform a successful site evaluation. 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.

• Ensure Compliance with Laws, Regulations, Codes, and Agreements: Ensure that any installation performed as a result of the site evaluation is in full compliance with applicable federal and local laws, regulations, electrical codes, building codes, and fire codes.

• Establish Radio Line of Sight between MDS FIVE Series Radios: The most critical step in conducting a site evaluation is confirming a clear visual and radio Line of Sight (LOS) between a near MDS FIVE Series Radio and a far MDS FIVE Series Radio. If LOS does not exist, another location must be used.

MDS FIVE Series Radios in a link must have a clear view of each other, or visual “line of sight”. Binoculars may be used evaluate the path from the desired location of the near MDS FIVE Series Radio to the desired location of the far MDS FIVE Series Radio.

To confirm Line of Sight:

- Ensure that no obstructions are close to the transmitting/receiving path. Take into

consideration trees, bridges, construction of new buildings, unexpected aerial traffic, window washing units, etc.

- Ensure that each MDS FIVE Series can be mounted in the position required to

correctly align the MDS FIVE Series with its link partner.

MDS FIVE Series Radios must also have a clear radio line of sight. If a hard object, such as a mountain ridge or building, is too close to the signal path, it can damage the r adio signal or reduce its strength. This happens even though the obstacle does not obscure the direct, visual line of sight. The Fresnel zone for a radio beam is an elliptical area immediately surrounding the visual path. It varies in thickness depending on the length of the signal path and the frequency of the signal. The necessary clearance for the Fresnel zone can be calculated, and it must be taken into account when designing a wireless links.

As shown in the picture above, when a hard object protrudes into the signal path within the Fresnel zone, knife-edge diffraction can deflect part of the signal and cause it to reach the receiving antenna slightly later than the direct signal. Since these deflected signals are out of phase with the direct signal, they can reduce its power or cancel it out

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. Contact your technical support representative for a copy of the spreadsheet.

 Determine MDS FIVE Series ODU Mounting Requirements: MDS FIVE Series ODUs can

be mounted on an antenna mast, brick, masonry or wall. Refer to detailed installation sections.

• Determine MDS FIVE Series SDIDU

Installation Location: MDS FIVE Series SDIDUsTM can be installed tabletop or cabinet, wall mount, or rack mount. The site must provide DC power or an optional AC/DC converter may be used. Refer to detailed installation sections.

• Document Potential Sources of Co-location Interference: When MDS FIVE Series ODUs are located on a roof or pole with other transmitters and receivers, an interference analysis may be required to determine and resolve potential interference issues. The interference analysis needs to be performed by an RF engineer. The specific information required for each transmitter and receiver includes the following:

- Transmitting and/or receiving frequency

- Type of antenna

- Distance from MDS FIVE Series ODU (horizontal and vertical)

- Polarity (horizontal or vert ical)

- Transmit power level

- Antenna direction

• Measure the Link Distance: The two ways to measure link distance are as follows:

- GPS: record the latitude and longitude for the ne ar and far MDS FIVE Series ODU

sites and calculate the link distance. Record the mapping datum used by the GPS unit and ensure the same mapping datum is used for all site evaluations in a given network.

- Range finder: measure the link distance (imperial or metric units may be used). Once the link distance has been measured, verify that the link distance meets the

availability requirements of the link. Microwave Data Systems has created a spreadsheet tool that calculates the link availability based on the details of the link. The Microsoft Excel spreadsheet is available on internet, at http://www.microwavedata.com/, and is shown on the following page. The following parameters should be entered (items in yellow):

• Operating Frequency: Enter 5800 or 5300

05-4498A01, Rev. G

User Reference and Installation Guide 3-9

• Transmit Antenna Gain: Enter 23 for the internal antenna or enter the gain of the external antenna if used.

• Transmit Output Power: Selectable between +5 to +23dB (5.8 GHz) and –18 to +5 (5.3 GHz) in 1 dB steps.

• Receive Antenna Gain: Enter 23 for the internal antenna or 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. As the curvature of the earth or other obstacles degrade the radio line of sight, the ratio can drop to –1. A separate spreadsheet is provided to calculate the appropriate ratio. In this spreadsheet the path length, tower heights and heights of any obstructions or ridges in the path of the link are entered.

• Climate Factor: Enter 0.1 for dry, 0.25 for average and 0.5 for humid environments

• Terrain Factor: Enter 0.25 for mountainous, 1 for average, and 4 for smooth (water)

+ G

– L

Path

+ G

RX ANT

Where: PTX is the transmitter output power (in dBm) G G L

is the Path loss, defined by:

P

is the gain of the transmit antenna (in dB), 23 dBi for ODU’s internal antenna

TX ANT

is the gain of the receive antenna (in dB), 23 dBi for ODU’s internal antenna

RX ANT

Where: F is the Frequency in MHz (5800 or 5300), D is the Distance of path in miles This link budget is very important in determining any potential problems during installation. The

expected RSL and measured RSL should be close (+/- 5 to 10 dB)

3.6.3.2 Fade Margin Calculation

The fade margin is the difference between the actual received signal and the MDS FIVE Series Radio’s threshold for the modulation mode selected. The fade margin can be used to determine availability and should be at least 10 dB.

05-4498A01, Rev. G

User Reference and Installation Guide 3-13

3.6.3.3 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. Availability is affected by the following:

• Path length

• Fade margin

• Frequency

• Terrain (smooth, average, mountainous, valleys)

• Climate (dry, temperate, hot, humid)

Depending on the type of traffic carried over the link and the overall network design redundancy, fade margin should be included to support the desired availability rate. Critical data and voice may require a very high availability rate (99.999% or 5.3 minutes of predicted outage per year). To improve availability, the fade margin can be increased by shortening the path length, transmitting at a higher power level, or by using higher gain antennas.

Availability can be computed using the following formula, which is known as the Vigants Barnett

Method.

Availability = 100 P = 2.5

× 10

× (1 – P)

-9

× C × F × D

3

× 10

(-FM/10)

Where F is the frequency in MHz (5300 or 5800) D is the distance in miles FM is the fade margin in dB C is the climate/terrain factor as defined below:

Humid/Over Water: C = 4 (worst case channel) Average Conditions: C = 1 Dry/Mountains: C = 0.25 (best case channel)

Example: Assume 21 dB fade margin, over 5 miles with average climate/terrain, at 5.8 GHz. The availability comes out to be 99.9986. This corresponds to the link being unavailable for 7.6 minutes per year.

3.6.4 Frequency Plan Determination

When configuring MDS FIVE Series units in a point-to-point or consecutive point configuration, careful engineering of the MDS FIVE Series frequency plans and antenna locations should be performed in order to minimize potential interference between nearby radios. Nearby radios should operate on different frequencies, transmitting in the same band (high side or low side).

05-4498A01, Rev. G

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

and Figure 3-4.

3.6.5 Antenna Planning

The ODU comes with a built in 23 dBi gain antenna. This should provide adequate link performance for most applications.

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. They are also more easily affected by wind.

Only directional antennas can be used with MDS FIVE Series radios. Consult factory for antenna manufacturer options.

The ISM (5.8 GHz) band does not restrict antenna gain or EIRP, therefore there is no need to back off transmit power due to excessive antenna gain.

1. Select where the cable will enter the building from the 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.

3.6.6 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.

If there are

05-4498A01, Rev. G

User Reference and Installation Guide 3-16

any questions on power settings refer to your professional installer in order to maintain the FCC legal ERP limits.

The SDIDU

TM

employs spectrally efficient shaped Quadrature Amplitude Modulation (QAM). This waveform is not a constant envelope waveform. Therefore, the average power and peak power are different. The difference in peak and average power depends on the constellation type and shaping factor, where spectral efficiency such as more constellation points or lower shaping factor leading to peak powers higher than average powers. The peak power is typically 5-7 dB greater than the average power in the SDIDU

TM

, and never exceeds 7 dB. Regulatory

requirements are usually based on peak EIRP which is based on peak power and antenna gain.

3.6.6.1 5.8 GHz Band

For fixed point-to-point applications in the United States the maximum EIRP (Effective Isotropic Radiated Power) is unlimited when using directional antennas in accordance with FCC part

15.247b(3). The ODU 5800 may therefore be operated at its maximum output power, +23 dBm, for maximum system gain.

EIRP is calculated for link budget with external antennas as, EIRP(avg) dBm = External Antenna Gain (dBi) + 23 dBm For internal antenna (23 dBi) EIRP is, EIRP(avg) = 46 dBm

3.6.6.2 5.3 GHz Band

In the 5.3 GHz U-NII band the peak EIRP (Effective Isotropic Radiated Power) is limited to +30 dBm at the antenna for bandwidths above 20 MHz and is reduced for narrower bandwidths in accordance with FCC part 15.407a(3).

The installer is responsible during set up of transmit power to not exceed FCC limits on transmission power. These maximum power levels are provided in Table 3-1 for both internal antenna and external antenna ODU configurations, along with the operational bandwidths.

Note that though regulatory limits are stated in terms of peak power, the system transmit power levels are calibrated as averaged power readings. Average power is used for link calculations. Therefore the levels provided in the following table is average power levels that have been certified to correspond with the maximum peak EIRP allowed.

3.6.6.2.1 ODU with Internal Antenna Table 3-1 indicates the maximum average transmit power setting that may be selected ODU 5300

with internal (23 dBi) antenna.

The number of supported channels per band (low band or high band) is shown in the link configuration wizard. The greater number of channels supported the lower the emission bandwidth for each channel.

05-4498A01, Rev. G

User Reference and Installation Guide 3-17

For link budget, EIRP(Avg) = 23 dBi + Tx Power Setting (dBm).

3.6.6.2.2 ODU with External Antenna When using external antennas with gains greater than 23 dBi, the transmit power must be

reduced in dB from that given in Table 3-1 by the antenna gain difference above 23 dBi for the mode that is being used.

For example, using a 6 foot dish antenna with 37 dBi gain, the output power would be dropped by Antenna Gain (External) – 23 dBi = Antenna Gain Difference

37.6 dBi – 23 dBi = 14.6 dB For mode 100FE1 (single channel configuration with 30MHz emission bandwidth) the power

would be lowered from Tx Power (Internal Antenna) – 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).

Power settings for other modes of operation can be easily extrapolated from

Table 3-2. For link

budget calculations, EIRP(Avg) dBm= Antenna Gain (dBi) + Tx Power Setting (dBm). Though transmitter radiated power is limited in the 5.3 GHz band regardless of antenna size, the

receiver benefits from gain of larger antennas.

3.7 Installation of the MDS FIVE Series

The following sections provide installation guides for:

• SDIDU

TM

Installation

• ODU Installation

3.7.1 Installing the MDS FIVE Series Software Defined IDU

The MDS FIVE Series SDIDU

TM

can be installed in the following three options:

TM

1. Table top or cabinet

2. Wall mount

3. Rack mount

The MDS FIVE Series SDIDU

TM

should be:

• Located where you can easily connect to a power supply and any other equipment used in your network, such as a router or PC.

• In a relatively clean, dust-free environment that allows easy access to the rear grounding post as well as the front panel controls and indicators. Air must be able to pass freely over the chassis.

• Accessible for service and troubleshooting.

• Protected from rain and extremes of temperature (it is designed for indoor use).

3.7.1.1 Installing on a Table Top or Cabinet

The MDS FIVE Series SDIDUTM can be placed on a tabletop or cabinet shelf. In order to prevent possible disruption, it is recommended to use a strap to secure the SDIDU

TM

.

3.7.1.2 Installing on a Wall

An installation option for the SDIDUTM is mounting the unit to a wall. If the wall mount option is being considered, plan to position the MDS FIVE Series SDIDU the connectors on the front panel, and the rear grounding post to be visible at all times and easily accessible. Also, including plastic clamps to support and arrange the ODU/ SDIDU

TM

at a height that allows LEDs,

TM

Interconnect Cable should also be considered.

User Reference and Installation Guide 3-22

3.7.1.3 Installing in a Rack

To rack-mount the SDIDUTM, use the supplied mounting brackets to secure the chassis to a 19 inch rack cabinet. As shown in enclosure. An optional 21 inch rack mount kit is also available (consult factory for details).

Figure 3-5. MDS FIVE Series SDIDUTM Dimensions

Figure 3-5, the brackets can be attached to the front sides of the

3.7.2 Installing the MDS FIVE Series ODU

The MDS FIVE Series ODU is intended for mounting on either a pole or antenna mast. Each site must be assessed for the mounting method, location, and height. After defining the

mounting location and height for the MDS FIVE Series ODU, re-confirm the line of sight. When operating a 1+1 configured SDIDU™, i.e. an SDIDU™ with two power supplies and two

modem modules installed, in 1+0 mode, the ODU must be connected to the modem in the bottom slot. If the ODU is connected to the modem in the top slot, the SDIDU™ will not communicate with the ODU, and a link cannot be established.

3.7.2.1 Installing the Mounting Poles

First install the mounting poles, on which you will mount the MDS FIVE Series ODU. It is important to note the direction in which the ODU will point when installing the mounting pole.

The mounting pole must be mounted in a vertical position. Failure to do so may result in improper alignment of the ODU. Vertical tilt of the ODU is accomplished from the tilt mounting bracket.

The mounting pole must be grounded. Now that you have installed the mounting pole, you are ready to install the MDS FIVE Series

ODU onto the mounting poles. Reference

Figure 3-6 through Figure 3-9.

05-4498A01, Rev. G

User Reference and Installation Guide 3-23

Figure 3-6. Mounting Parts for the MDS FIVE Series 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. Repeat this step for the second U-bolt.

3. Place the MDS FIVE Series ODU on the mating half of the tilt bracket connected by the

two center bolts.

4. Add the remaining four bolts to the tilt bracket but do not tighten until the antenna

alignment is complete (only applies for internal antenna ODUs).

5. Manually point the ODU in the direction of the link partner ODU.

3.7.3 Routing the ODU/ SDIDU

TM

Interconnect Cable

1. Select where the cable will enter the building from outside.

05-4498A01, Rev. G

User Reference and Installation Guide 3-25

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.

The SDIDU

TM

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 SDIDU

TM

. This cable assembly may be supplied in fixed lengths with the digital radio. Bulk coaxial cable of equivalent specification may also be used, with terminating connectors applied during cable installation.

TM

Based on an evaluation of the cable routing path, pull the ODU/SDIDU one unit to the other, utilizing cable trays, ducts, or conduit as required. Take care that the ODU/ SDIDU protect the TNC connectors from stress, damage and contamination during installation (do not pull the cable by the connectors). If multiple ODU/ SDIDU

TM

Interconnect cable is not kinked or damaged in any way during installation. Be sure to

TM

Interconnect cables are to be installed along the same route, the cables should all be pulled at one time. Be sure the installed cable does not have any bends that exceed the specified cable bend radius. The ODU/ SDIDU

Interconnect cable from

TM

Interconnect cable should be adequately supported on horizontal runs and should be restraine d by hangers or ties on vertical runs to reduce stress on the cable. Outside the building, support and restrain the cable as required by routing and environmental conditions (wind, ice).

TM

The MDS FIVE Series ODU/SDIDU

and interconnection must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires that the ODU, any mounting pole or mast and any exposed interconnect cable be grounded on the outside of the structure. The SDIDU

TM

must be grounded to a rack or structure ground that also has direct

path to earth ground. The ODU must be directly connected to a ground rod or equivalent earth ground. The ODU/

SDIDU

TM

interconnect cable should also be grounded at the ODU, where the cable enters the structure and at intermediate points if the exposed cable run is long (typically at intervals of 100 ft), with the cable manufacturer’s grounding kits. Lightning protection devices used with the interconnect cable must be appropriate for the transmission of the interconnect signals (DC to 350 MHz).

Provide a sufficient but not excessive length of cable at each end to allow easy connection to the ODU and SDIDU outdoors, should be avoided to minimize signal attenuation and provide a more robust and reliable installation. If installing using bulk coaxial cable, terminate the ODU/ SDIDU Interconnect cable at each end with a TNC male connector on the SDIDU

TM

without stress or tension on the cable. Excessive cable length, especially

TM

side and either a N-

TM

type or TNC male connector on the ODU side that is appropriate for the cable type. Use of connectors, tools and termination procedures specified by the cable manufacturer is recommended.

Once the cable has been installed but before connection has been made to either unit, a simple DC continuity test should be made to verify the integrity of the installed cable. A DC continuity tester or digital multimeter may be used to verify a lack of DC continuity between the cable center conductor and outer conductor, with the opposite end of the cable unconnected. With a temporary test lead or shorting adapter connected to one end of the cable, DC continuity should be verified between the center and outer conductors at the opposite end.

FACTORY SERVICE

Component level repair of radio equipment is not recommended in the field. Many components are installed using surface mount technology, which requires specialized training and equipment for proper servicing. For this reason, the equipment should be returned to the factory for any PC board repairs. The factory is best equipped to diagnose, repair and align your radio to its proper operating specifications.

If return of the equipment is necessary, you will be issued a Service Request Order (SRO) number and return shipping address. The SRO number will help expedite the repair so that the equipment can be repaired and returned to you as quickly as possible. Please be sure to include the SRO number on the outside of the shipping box, and on any correspondence relating to the repair. No equipment will be accepted for repair without an SRO number.

A statement should accompany the radio describing, in detail, the trouble symptom(s), and a description of any associated equipment normally connected to the radio. It is also important to include the name and telephone number of a person in your organization who can be contacted if additional information is required.

The radio must be properly packed for return to the factory. The original shipping container and packaging materials should be used whenever possible.

When repairs have been completed, the equipment will be returned to you by the same shipping method used to send it to the factory. Please specify if you wish to make different shipping arrangements. To inquire about an in-process repair, you may contact our Product Services Group at 585-241-5540 (FAX: 585-242-8400), or via e-mail at: ProductServices@microwavedata.com
