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 in close proximity to the front of the antenna while the transmitter is

operating. The antenna will be professional installed on fixed-mounted outdoor permanent

structures to provide separation from any other antenna and all persons as detailed on page 1-3.

Protection from Lightning

Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio

and television lead-in cables must have adequate surge protection at or near the point of entry to

the building. The code specifies that any shielded cable from an external antenna must have the

shield directly connected to a 10 AWG wire that connects to the building ground electrode.

Warning – This is a Class A product

Warning – This is a Class A product. In a domestic environment this product may cause radio

interference in which case the user may be required to take adequate measures.

2 System Description

2.1 About This Manual

This manual is written for those who are involved in the “hands-on” installation of the

MDS FIVE Series Digital Transceiver, such as installation technicians, site evaluators, project

managers, and network engineers. It assumes the reader has a basic understanding of how to

install hardware, use Windows® based software, and operate test equipment.

The MDS FIVE Series includes a Software Defined Indoor UnitTM (SDIDUTM) and outdoor unit

(ODU). The SDIDUTM is a product and trademark of CarrierComm.

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.

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.

The MDS FIVE Series is composed of a Software Defined Indoor UnitTM (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 SDIDUTM is provision for a second plug-in modem/IF module to

provide repeater or east/west network configurations.

The overall architecture consists of a single 1RU rack mount Software Defined Indoor Unit

(SDIDUTM) with a cable connecting to an Outdoor Unit (ODU) with an external antenna.

Power Supply Input

DC Input

-48 VDC

-48v (Isolated Input); 2-pin captive power connector. The

MDS FIVE Series requires an input of -48 volts dc ±10% at

the front panel DC Input connector. The total required power

is dependent on the option cards and protection configuration

(1+0, 1+1). The SDIDUTM front panel power connector pin

numbering is 1 through 2, from left to right, when facing the

unit front panel. Pin 1 is the power supply return and is

connected to unit chassis ground internally. Pin 2 should be

supplied with a nominal -48 V dc, with respect to the unit

chassis (ground). A ground-isolated supply may be used,

provided it will tolerate grounding of its most positive output.

The recommended power input is -44 to -52 V dc at 2 Amps

minimum. It is recommended that any power supply used be

able to supply a minimum of 100 W to the SDIDUTM.

A mating power cable connector is supplied with the MDS

FIVE Series SDIDUTM. It is a 2-pin plug, 5 mm pitch,

manufactured by Phoenix Contact, P/N 17 86 83 1

(connector type MSTB 2,5/2-STF). This connector has

screw clamp terminals that accommodate 24 AWG to 12

AWG wire. The power cable wire should be selected to

provide the appropriate current with minimal voltage drop,

based on the power supply voltage and length of cable

required. The recommended wire size for power cables

under 10 feet in length supplying -48 Vdc is 18 AWG.

The SDIDUTM supplies the ODU with all required power via

the ODU/SDIDUTM Interconnect cable. The MDS FIVE

Series SDIDUTM does not have a power on/off switch. When

DC power is connected to the SDIDUTM, the digital radio

powers up and is operational. There can be up to 320 mW of

RF power present at the antenna port (external antenna

version). The antenna should be directed safely when power

is applied.

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 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. This SDIDUTM /ODU architecture is

advantageous when compared to a single IDU with external mount antenna since supporting a

signal of 5.8 GHz from the IDU rack to the antenna will result in significant signal degradation,

which would require expensive coaxial cable or waveguide.

Figure 2-4 shows the SDIDUTM and interfaces from a functional point of view. The functional

partitions for the I/O, Modem/IF, and power supply modules are shown. The SDIDUTM comes

with the standard I/O capability that can be upgraded. In addition, the Modem/IF function is

modular. This allows the addition of a second Modem to support protection or ring architectures.

The power supply is similarly modular.

The SDIDUTM interfaces with the ODU to receive and provide modulated transmit and receive

waveforms. The SDIDUTM interfaces provide Fast Ethernet 100Base-T (MDS FIVE Series-100)

connections to the network. Contact factory for availability of SONET OC-3 (MDS FIVE Series-

155) connections. In addition, two E1/T1 channels are provided for PBX extension. SNMP is

provided on 10/100BaseT ports.

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). Table 2-5

summarizes the TCM/convolutional code rates for each modulation type supported by the MDS

FIVE Series.

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

• I/O Processing – The SDIDUTM 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 SDIDUTM architecture is flexible and allows for the addition of other I/O types in the

future.

• Switch/Framing – The SDIDUTM 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.

• Network Processor – The SDIDUTM includes a Network Processor that performs SNMP and

Network Management functions.

• Modem/IF – The SDIDUTM 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.

• Power Supply – The SDIDUTM 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

User Reference and Installation Guide 2-14

05-4498A01, Rev. G

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.

In the receive mode, the Framer separates the combined data stream received from the 64-QAM

Modem. The SDIDUTM supports Scalable Ethernet data rates, such as 25 or 50 Mbps via the

100BaseT data interface port. The SDIDUTM 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 SDIDUTM 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 Figure 2-5). This architecture lets providers

deliver high bandwidth with high availability to their customers.

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 Figure 2-6. . For 2 x 1+0 and 2 x 1+1 nodes payload and NMS connections

need to be jumpered between two SDIDUTMs. For 1 x 2+0 nodes, there is no need for jumpers as

there is a single SDIDUTM. For SDH or SONET payloads, the configuration is similar but an

external add/drop mux and a second SDH/SONET interface card are required.

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. The SDIDUTM is connected

to two ODUs, one broadcasting/receiving in one direction of the ring architecture and the other

broadcasting/receiving in the other as shown in Figure 2-7.

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

05-4498A01, Rev. G

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 SDIDUTM contains two power

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.

User Reference and Installation Guide 2-18

2.9.1 Protected Non-Diversity (Hot Standby)

Figure 2-8Error! Reference source not found. shows operation in Protected Non-Diversity

mode, also called Hot Standby. In this mode, one ODU at each location transmits to two ODUs

at the other location. This mode does not require the extra bandwidth or interference protection.

It provides hitless receive switching and hot standby. The SDIDUTM automatically switches

transmit ODU upon appropriate ODU alarm or ODU interface error, minimizing transmit outage

time.

In Protected Diversity mode, the link between each pair of modems is the same, as shown in

Figure 2-9Error! Reference source not found., providing complete redundancy. This

arrangement requires bandwidth for both links and non-interference between the links, but it

provides hitless receive and transmit switching. The SDIDUTM supports both frequency and

spatial diversity.

2.9.2.1 Frequency Diversity

In frequency diversity, two frequencies are used to achieve non-interference. The proprietary

framer chooses the best, or error-free, data stream and forwards it to the Line Interface Units

(LIUs).

2.9.2.2 Spatial Diversity

In spatial diversity, two non-interfering paths are used. The proprietary framer chooses the best,

or error-free, data stream and forwards it to the Line Interface Units (LIUs).

2.9.2.2.1 Single Transmitter

Protected Non-Diversity, or Hot Standby, is also refered to as Single Transmitter Spatial Diversity.

For more information on this mode, see Section 2.9.1.

2.9.2.2.2 Dual Transmitter

When using Dual Transmitter Spatial Diversity, two active transmitters are physically isolated to

avoid crosstalk.

2.10 1 + 1 Multi-hop Repeater Configuration

The MDS FIVE Series supports a 1 + 1 multi-hop repeater configuration with drop/insert

capability as shown in Figure 2-10. This configuration provides individual 1 + 1 link protection as

described in section 2.8, as well as the full-scale protection inherent in the consecutive point

architecture as described in section 2.6. At each location within the network, data may be

dropped or inserted. Front panel connections for drop/insert capability are shown in Figure 2-11.

In this configuration each SDIDUTM contains two power supplies and two modems.

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 data-

bandwidth.

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 Figure 2-12. Flexible channel mapping allows selection from predefined

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 Figure 2-13. In the repeater example, the

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

05-4498A01, Rev. G

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 the MDS FIVE Series use a unique

power control technique called AdTPC. AdTPC enables MDS FIVE Series units to transmit at the

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. AdTPC also extends the concept of power

management by controlling not only the power (dBm) of the RF signal, but its quality (signal-to-

noise ratio) as well.

In contrast to ATPC, the AdTPC technique dynamically adjusts the output power based on both

the actual strength and quality of the signal. Networked MDS FIVE Series units constantly

monitor receive power and maintain 10-12 BER performance under varying interference and

climate conditions. Each MDS FIVE Series unit can detect when there is a degradation in the

received signal level of quality and adjust the transmit power level of the far-end MDS FIVE

Series unit to correct for it.

AdTPC provides maximum power in periods of heavy interference and fading and minimum power

when conditions are clear. 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. The resulting benefit is that operators are able to deploy more MDS FIVE

Series units in a smaller area.

2.14 MDS FIVE Series Software and Network

Management

All of the MDS FIVE Series parameters are accessible in three ways:

1. Using a standard web-browser via HTTP to 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.

The GUI, SNMP, and CLI control are discussed in the MDS FIVE Series User Interface Manual.

User Reference and Installation Guide 2-24

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 Spanning-

Tree 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. Figure

2-14 shows the PC and both SDIDUs™ in the same subnet. In this case, no router is required.

Figure 2-15 shows the PC and one of the SDIDUs™ in one subnet and the other SDIDU™ in

another. In this case, a router is required. Note how the GW addreses are set to allow

communication from the PC to the SDIDU™ in the other subnet.

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

05-4498A01, Rev. G

• Confirm

• Line of sight for each link

• MDS FIVE Series ODU mounting locations

• 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.

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 radio

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

05-4498A01, Rev. G

User Reference and Installation Guide 3-8

05-4498A01, Rev. G

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 SDIDUTM 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 vertical)

- 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 near 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

User Reference and Installation Guide 3-9

05-4498A01, Rev. G

• 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)

• Determine the Length of Interconnect Cable from ODU to SDIDUTM: The primary

consideration for the outdoor interconnect cable from the ODU to SDIDUTM is the distance

and route between the ODU and SDIDUTM. Maximum cable lengths are listed in Table

3-1.

Select the Grounding Location for both the MDS FIVE Series ODU and SDIDUTM: The MDS

FIVE 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 FIVE Series SDIDUTM.

• Ensure Building Aesthetics: Ensure that the ODU can be mounted so that it is

aesthetically pleasing to the environment and to the property owner. Aesthetics must be

approved by the property owner and the network engineer.

• Take Site Photographs

• Sketch the Site

3.6.3 Critical System Calculations

3.6.3.1 Received Signal Level (RSL) and Link Budget

The received signal level (RSL) can be estimated using the following formula:

RSL (dBm) = PTX + GTX ANT – LPath + GRX ANT

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

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

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

LPath is the Path loss, defined by:

LP (dB) = 36.6 + 20log10(F*D)

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.

User Reference and Installation Guide 3-13

05-4498A01, Rev. G

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 × (1 – P)

P = 2.5 × 10-9 × C × F × D3× 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).

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 and Figure 3-4.

The channel assignments shown in the figures correspond to the channel numbers entered via

the graphical user interface (GUI) or SNMP.

Figure 3-4. MDS FIVE Series Channel 5.3 GHz Frequency Plan

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

05-4498A01, Rev. G

any questions on power settings refer to your professional installer in order to maintain

the FCC legal ERP limits.

The SDIDUTM 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 SDIDUTM, 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.

User Reference and Installation Guide 3-17

05-4498A01, Rev. G

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).

* Note: Many antenna manufacturers rate antenna gain in dBd (dB referred to a dipole antenna)

in their literature. To convert to dBi, add 2.15 dB.

User Reference and Installation Guide 3-18

05-4498A01, Rev. G

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:

• SDIDUTM Installation

• ODU Installation

3.7.1 Installing the MDS FIVE Series Software Defined IDUTM

The MDS FIVE Series SDIDUTM can be installed in the following three options:

1. Table top or cabinet

2. Wall mount

3. Rack mount

The MDS FIVE Series SDIDUTM 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 SDIDUTM.

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 SDIDUTM at a height that allows LEDs,

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/ SDIDUTM

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

enclosure. An optional 21 inch rack mount kit is also available (consult factory for details).

Figure 3-5. MDS FIVE Series SDIDUTM Dimensions

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/ SDIDUTM Interconnect Cable

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

05-4498A01, Rev. G

User Reference and Installation Guide 3-25

05-4498A01, Rev. G

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 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. 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.

Based on an evaluation of the cable routing path, pull the ODU/SDIDUTM Interconnect cable from

one unit to the other, utilizing cable trays, ducts, or conduit as required. Take care that the ODU/

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

protect the TNC connectors from stress, damage and contamination during installation (do not

pull the cable by the connectors). If multiple ODU/ SDIDUTM 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/ SDIDUTM

Interconnect cable should be adequately supported on horizontal runs and should be restrained

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).

The MDS FIVE Series ODU/SDIDUTM 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 SDIDUTM 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/

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

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/ SDIDUTM

Interconnect cable at each end with a TNC male connector on the SDIDUTM side and either a N-

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.

3.9 SDIDU™ Service

At times, it may be necessary to service the SDIDU™. This may include installing, removing, or

replacing an SDIDU™ module. There may be up to 8 modules installed in a single SDIDU™

chassis. Figure 3-14 shows the front panel of the SDIDU™ with each module labeled. The basic

procedure for removing and installing a module is common to all the modules, with slight

variations for the Power Supply Module, Controller Module, and Mini IO Module. These basic

procedures are described below. Variations are described in sub-items beneath each step.

Figure 3-14 SDIDU™ Modules

3.9.1 Removing a Module

1. Modules are static sensitive and should only be handled in an ESD-safe environment.

When packaging modules for shipment or storage, place in an ESD bag.

2. Remove front panel connections to the module.

3. Remove the two thumbscrews on either side of the module. Figure 3-15 shows the

locations of these thumb screws.

4. The thumbscrew for the Standard IO Module is located on the right side of the Mini IO

Module slot.

5. If a Mini IO module is installed and the Standard IO Module is to be removed, both

modules will be removed as one unit.

6. When removing only the Mini IO card, remove the corner screw indicated in Figure 3-15

and one thumb screw.

7. Thread thumbscrew(s) into hole(s) shown in Figure 3-16. Remove the module by

grasping the thumbscrew(s) and pulling module straight out of the SDIDU™. Both

thumbscrews should be used for all modules except the Power Supply and the Mini IO

Modules.

8. The Power Supply and Mini IO Modules have only one threaded hole each.

9. When removing the Standard IO Module, the ground lug indicated in Figure 3-16 is used

as the second threaded hole. If the SDIDU™ is to remain powered on and the ground lug

is being used to ground the unit, first move the ground connection to the ground lug

located on the Controller Module.

The SDIDU™ retains its current configuration when a module is removed, unless that

module is the Controller Module. In which case, the IP addresses will need to be

reprogrammed.

Figure 3-16 Threaded Hole Locations

3.9.2 Installing a Module

1. Modules are static sensitive and should only be handled in an ESD-safe environment.

When packaging modules for shipment or storage, place in an ESD bag.

2. Line up the module board with the guides in the chassis and slide the module into the

SDIDU™. Figure 3-17 shows a photo of the guides. As the module face plate comes flush

with the face of the SDIDU™, connectors on the back of the module will engage with the

SDIDU™ backplane. It is possible to encounter interference from adjacent module front

panels. If this occurs, loosen the thumbscrews holding the neighboring panels and shift

them as necessary to ensure fit.

a. The Mini IO Module only has one guide on the right side. Take care to insert the Mini

IO module carefully and correctly engage the rear connector with its mate on the

Standard IO Module.

3. Install thumbscrews on either side of the module as shown in Figure 3-15.

a. The Mini IO card has a corner screw which should be installed. This corner screw is

shown in Figure 3-15.

4. Make front panel connections to the module and power on the SDIDU™ if necessary.

5. Verify proper operation of the unit.

a. If the Controller Module has been changed, reprogram the IP addresses.

IN CASE OF DIFFICULTY...

MDS products are designed for long life and trouble-free operation. However, this equipment, as

with all electronic equipment, may have an occasional component failure. The following

information will assist you in the event that servicing becomes necessary.

TECHNICAL ASSISTANCE

Technical assistance for MDS products is available from our Technical Support Department

during business hours (8:00 A.M.–5:30 P.M. Eastern Time). When calling, please give the

complete model number of the radio, along with a description of the trouble/symptom(s) that you

are experiencing. In many cases, problems can be resolved over the telephone, without the need

for returning the unit to the factory. Please use one of the following means for product assistance:

Phone: 585 241-5510 E-Mail: mailto:TechSupport@microwavedata.com

FAX: 585 242-8369 Web: http://www.microwavedata.com/

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:
