Introduction to Chapter 1
Chapter 1 is aimed at management and planning staff to provide a system overview of the HDR5 System. This overview includes technical specifications, system description, features and logistic requirements for the HDR5 System.
HighReach HDR5 Product Family
The HDR5 System design philosophy was to create a compact, cost-effective digital microwave radio successor to the HDR4 System. This involves a version of the IDU that is software configurable to various data rates and modulation schemes. Thus the system may be re-configured without any module or hardware changes. The range of ODUs has also been extended and rationalised.
This has resulted in the following product family:
The HDR5 1U IDU: Configurable from 4 to 16 E1 tributaries plus standard 10/100BaseT Ethernet interface with configurable throughput capacity up to 68 Mbps.
The HDR5 2U IDU versions to cover protection (1+1) and higher E1 capacity (up to 32E1).
The HDR ODU range: In bands from 4 to 38 GHz
The ODUs remain data rate independent and the IDUs are independent of ODU frequency band (with the exception of the 4.5GHz ODU which requires a different modem). Current and previous versions of ODU are compatible with HDR5 IDUs. Old version HDR ODUs require a different IDU Modem.
Role and Purpose
The HDR5 System provides a full duplex, point-to-point, digital radio link for low to medium data rate communications links. It is used to transport digital data between two sites.
Whether the digitally encoded information is voice, telephony, cellular, data or video as required by various applications, the HDR5 System product can be deployed in urban and rural networks as an interconnect solution.
Typical roles include:
First-mile cellular interconnect applications
HighReach (HDR5 Series) System Manual Chapter 1
Page 1-4 Issue 4 (October 2009)
Last-mile communications network applications such as spur-links off SDH networks
Permanent rural telecommunications infrastructure Data Network or LAN/WAN interconnect for businesses Video Conference Links for Businesses Temporary infrastructure while optic fibre is installed Emergency communication services for disaster recovery Outside Broadcast or Temporary Cell Base interconnect.
Brief Description
An HDR5 System is a Digital Radio Link (DRL) comprising two Digital Radio Stations (DRS) positioned in a line of sight. Each DRS consists of an HDR5 IDU and an HDR ODU, interconnected by a coaxial cable. The ODU is connected to an antenna. For the standard (1+0) unprotected configuration, there is one IDU and one ODU. A 1+1 protected version of the HDR5 IDU is also available in a 2U version. This version has two PSUs and two Modems that each connect to an ODU. This is for hot standby and diversity redundancy protection applications.
The HDR5 System can connect up to 32 E1 (2048 kbps) tributaries and a single 10/100BaseT Ethernet port. The system is available for operation in a number of frequency bands (see Features on page 1-7). Figure 1-1 and Figure 1-2 show the 1+0 and 1+1 IDUs respectively, while Figure 1-3 shows a typical ODU with integrated antenna.

Features
Main Characteristics
a. The HDR5 system caters for 1E1 to 32E1 capacities for channel spacing of 7, 14 and 28 MHz.
b. QPSK or 16QAM modulation may be used. 16QAM allows twice the data rate for specific channel spacing.
c. The 10/100BaseT Ethernet interface utilises bandwidth not used by E1 traffic. Bandwidth for disabled tributaries is allocated to Ethernet. This is performed as a native E1/native Ethernet system. A maximum Ethernet throughput of 66Mbps is achievable (for a 16QAM system with 28 MHz channel).
d. Refer to Table 1-1 for the E1 and Ethernet capacities available for the various channel spacing.

Optional Features
The HDR System offers the following optional features:
Protected System (1+1)
A protected system provides the user with a level of protection against:
Module failure of those modules with lowest MTBF, such as Modem module and Outdoor Unit.
Propagation path disturbances when using space or frequency diversity.
In addition, the hit-less receive switching provides the user with the instantaneous best receiver at all times, thus adding an effective coding gain to the system performance.
In summary, the purpose of a protected system is to ensure minimum downtime of the HDR System under propagation and module failures.
The HDR System can be configured or upgraded to operate in one of two protected modes.
Hot Stand-by (employing space diversity). Dual Path (employing space and frequency diversity).
Usually, this selection is dependent on availability of spectrum and desired performance.
In both of these configurations, the HDR5 IDU is connected to two Outdoor Units.
The 1+1 version of the IDU uses a 2U height assembly with two power supplies and two Modems (one for each ODU).
HighReach (HDR5 Series) System Manual Chapter 1
Page 1-10 Issue 4 (October 2009)
Hot Stand-by Protection
Figure 1-4 on page 1-11 shows the principle of the hot stand-by protection configuration.
The hot stand-by protection system uses a common frequency channel, with only one of the two transmitters at any end of the microwave link active at any particular time. The transmitter in stand-by mode will be fully operational except that it will be muted.
The two transceivers on a particular side of a link are the same type (i.e. both high band or both low band). Both of the receivers on a particular side of the link are always active. This establishes two distinct propagation paths in each direction across the link for one of the four possible transmitter-receiver combinations. Note that it does not matter which one of the two transmitters on a given side of the link is active.
The hot stand-by protected system configuration provides hit-less receiver changeover on each side of the radio relay link in case of receiver equipment failure or sudden propagation path fading on one of the four microwave paths. If a transmitter fails, there will be a short break in transmission until the stand-by transmitter is activated. In contrast to receiver changeover, transmitter changeover will therefore not be hit-less.
Dual Path Protection (Frequency Diversity) Figure 1-5 on page 1-12 shows the principle of the Dual path protection configuration.
In the dual path protected system configuration both transmitters at each end will be active (they operate in different frequency channels). Both of the receivers on a particular side of the link will be active, each receiving on its set channel frequency. This establishes two entirely independent bi-directional microwave links.

Important Points to Remember Indoor Units must be fitted with duplicate Modems in terms of data
rate and Modulation Type. Each Radio Station should have installed Outdoor Units of the
same type (either both High Band or both Low Band). Outdoor Units should be of the same Band (7, 8, etc.) and sub-
band designator (A1, B1, etc.) for hot standby operation. Configuration of Protected mode is dependent on the frequency
(channel) selection for the Outdoor Units. Maximum physical separation of the Outdoor Units at either side
of the link is a function of the antenna 3 dB beamwidth and the physical separation between the two stations.
Configuration and Management Options
The HighReach HDR5 System offers the following configuration and management tools:
Configuration Tool Application
The Configuration Tool Application is an on-site software tool for status monitoring and configuration of the digital radio site (DRS) and is used as a craft terminal. The application runs on a user supplied PC connected to the IDU via a USB cable.
The Configuration Tool allows the user to configure and view the local (only) IDU/ODU combination and monitor the local and remote alarms.
For more information on the Configuration Tool refer to Chapter 7.
Web Page Application
Each HDR5 IDU has an IP address and Configuration Web Page configured within. Status monitoring and configuration is performed using the IP address from a standard web browser and with the network connected to the O&M port of the IDU.
Each HDR5 IDU is configured with a unique MAC Address and default IP Address, for ease of initial configuration on a unit by unit basis.
Once the original configuration is completed then the client may change the IP Addresses of each IDU, to suit his Network requirements.
Refer to Figure 1-6 Network and VoIP LAN connections using O&M Bridge connector on page 1-15.
HighReach (HDR5 Series) System Manual Chapter 1
Page 1-14 Issue 4 (October 2009)
SNMP Management Application
Each HDR5 IDU also has an SNMP Agent and MIB installed. This allows network management in the form of fault reporting, status polling and configuration to be performed within a large network of elements by a generic network management system utilising an SNMP Manager such as HP Openview

Planning Information
Site Evaluation
When planning a site for a digital radio link (DRL), it is important to take into account the operational environment of the proposed site.
The combined effect of atmospheric environmental factors such as rain and lightning, atmospheric attenuation, signal path obstruction, propagation fading, air temperature gradients, ice build-up, wind and solar radiation can contribute towards reducing the level of performance of the system (as measured in terms of its capability to transfer data without error). In the higher frequency bands above 13GHz, especially in the 23 GHz water absorption band, rainfall is the main attenuation mechanism that limits error performance. Ice and snow will obviously have a similar effect. Severely cold, and excessively warm climatic conditions outside the scope of the operating temperature range can affect the function of the system, especially the outdoor equipment, antennas, cabling and connectors (Refer to Table 1-14: Environmental Specifications on page 1-27). Insufficiently rigid masts in very strong windy conditions can affect the antenna beam alignment and hence the ODU equipment reliability due to wind force stress build-up and/or vibration in the mast-mounted equipment.
Non-atmospheric environmental factors such as the electromagnetic interference due to the presence of other antennas, path clutter and terrain topography can also have a detrimental effect on system performance and should be carefully assessed before and during installation.

All the Indoor Units interfaces, e.g. data, power and IDU/ODU connector, are located on the front of the unit making the IDUs ideally suitable for rack installations in accordance with the ETSI standard.
Front panel connection philosophy eases the commissioning and testing procedures of the equipment.
Outdoor Unit
The ODU is designed for mounting on one of a series of RFS antennas (see Antennas below for the full range). These antennas are based on RFS SlimLine and CompactLine antenna ranges customised to allow integral mounting.
The ODU may also be mounted separately on a mast using the optional HighReach Mast Mount Kit (MMK), usually for larger than 1.8m diameter non-customised RFS standard antennas and the 4.5GHz ODU. In this configuration, the ODU is connected to an antenna by a flexible waveguide between the waveguide flange on the ODU and the antenna. In the 4.5GHz ODU case, a co-axial cable is used to connect the ODU to the antenna.
The ODU has a mass of < 9 kg and can be installed by one person, and is suitably enclosed for all-weather operation.
See Mechanical specifications on page 1-27 for the various pole diameters on which the ODU can be mounted.
Antennas
For optimum performance, a range of RFS antennas has been customised (by RFS) allowing for integral mounting of the HDR5 ODUs. The following antenna dish sizes are available for the integral mounting configuration:
0.3 m, 0.6 m, 1.2 m and 1.8 m.
The 4.5GHz ODU uses an N-type RF output connector, and needs to be connected to N-type antenna using a suitable co-axial cable.
Alignment of the two antennas of a DRL can be performed by one person at each site. Antenna alignment (beaming-up) is assisted by use of a DVM connected to the RSSI BNC connection on the ODU.

Configuration Capabilities of the HDR5 System
The standard methods of monitoring and configuration of the HDR5 System is via the on site configuration tool or web page browser. The configuration tool can only monitor and configure the local DRS. In both cases the structure of screens is the same.
There are seven main screens that can be viewed:
1. Alarm Status
This screen gives all information on the IDU and ODU Status e.g. tributary status, Ethernet status, alarms status, PSU voltages, lock status, transmit level, receive level, channel configuration.
2. Alarm Log
Provides a log of all alarm events since previously cleared.
3. Build History
Provides information for configuration management in terms of Part and Version Numbers for the various Hardware, Software and Firmware installations in the IDU and ODU.
4. Performance Monitoring
Provides performance statistics in terms of link availability (G.826) and receive levels in 15 minute intervals, as well as daily totals for the past 30 days.
5. Configuration
This screen allows the user to configure the IDU and ODU e.g. IP address, active tributaries, loopbacks, transmit level, ODU channel settings.
6. Upgrade
Allows software and firmware download to the IDU.
7. Security
Allows user access and security levels to be set.
The configuration tool has an extra settings screen for serial port configuration and default setting. The web page has an extra frequency offset table screen and network bandwidth setting screen.
Maintenance Philosophy
General
The HDR5 Maintenance Philosophy can be described in two main categories:
862-02701 Chapter 1 HighReach (HDR5 Series) System Manual
Issue 4 (October 2009) Page 1-19
Routine (non-invasive) Maintenance It is recommended that the client, on a routine basis, every 3 or 4
months do routine tasks at the DRS and a visual inspection of the equipment.
The type of tasks recommended are; blowing dust out of the racks, cleaning filters, and checking operation of standby generators, visually inspect connections and take corrective action if necessary.
It is also recommended that all the voltages and currents are noted and checked against a recorded history of previous visits. This is to track changes in parameters that may indicate that a failure is imminent, e.g. lock voltages or RSSI voltages.
Major (invasive) Maintenance It is recommended that the client annually, preferably just before
the rainy season or winter, complete additional system invasive tasks during a planned down-time.
These tasks should include a full inspection of the IDU/ODU cable and its connectors. Re-make connections off where necessary, replace cable if necessary, replace tie-wrapping of cable to mast, redo all the connectors insulation.
Check the antenna mounting stability, re-pan if RSSI determines necessity.
Tie-wrap loose cables in Radio Room, neaten everything up, check that labelling is accurate, re-make off any suspicious connections.
Check the station ground connections and measure the resistance to ground, redo if necessary.
A complete BER performance Test should be done on a random sample of a few tributaries, check operation of VoIP links, ensure that all is functioning within specification.
The above checks are examples of what should be completed; the client needs to determine his specific requirements and schedule.
Fault Finding Philosophy
General
Fault finding is structured to ensure that any fault on the HDR5 System can be diagnosed and repaired with the minimum system downtime. With this in mind, fault diagnosis is divided into two main categories:
a. Diagnosing the most likely Faulty Site (Near or Far). b. Diagnosing the Faulty Line Replaceable Unit (LRU) at the Site
(IDU, ODU or IDU/ODU Interconnection Cable).
HighReach (HDR5 Series) System Manual Chapter 1
Page 1-20 Issue 4 (October 2009)
System performance evaluation is aided by diagnosing the radio link performance data for error performance (G.826).
Automatic Monitoring and Built-in Testing Capabilities
Apart from continuous monitoring of data and equipment fault states and conditions, with automatic fault warnings, the HDR5 System provides built-in test features for user maintenance/fault finding support.
The built-in test facilities can be operated on the Local IDU/ODU via the Configuration Tool or remotely on any of a number of DRSs via a web browser and/or SNMP Manager. The built-in test facilities allow the user to detect faults and to locate the defective part to a level of field, depot or factory repairable module. The major test features include:
Loopback of data signals at Tributary I/O and IDU (to ODU) I/O levels. ODU loopback is available on the 4.5GHz ODUs only.
Control of RF power level and muting. Display of signal levels and quality. Complete status display of equipment faults. For example,
synthesizer lock loss, power supply voltage or current, data error rates and general equipment status.
Insertion of AIS (all 1s) on tributaries to indicate upstream loss of integrity on data.
Disabling of modulation on carrier.

Protected System Data Transmission Characteristics
Receive Changeover
The Changeover of receivers is hit-less.
When a Changeover is required, such a swapping from active device to standby device is deemed hitless where the disruption to user traffic does not cause consecutive bit errors, a pattern slip, or a frame alignment synchronisation.
Transmit Changeover
In the case of Transmit Changeover, the user will experience loss of data for the period of the Changeover delay.
Protected System Characteristics
Protection Mode
Table 1-15: Protection Mode Characteristics Description Characteristics
Techniques Hot Stand-by (when the transmit frequencies of both links are identical) or Dual Path (when the transmit frequencies are different for each link)
Configuration Single IDU with two ODUs per station
Operational Mode Auto/Manual
The user can select either Manual control (where the user dictates the selection of optimal radio link), or alternatively, Automatic control. In this mode, the selection of the receive path is under system control and selection of the transmitter (Hot-Standby Mode only) is under system control.
862-02701 Chapter 1 HighReach (HDR5 Series) System Manual
Issue 4 (October 2009) Page 1-29
Receiver Changeover Conditions
The hit-less switching FEC/Protection section governs selection of the best receiver.
The Changeover from one receiver to the other should take place in a hit-less fashion under the following conditions:
Automatically (when Auto Mode is selected) when there are un-correctable errors on the current channel and no un-correctable errors on the other channel.
Manually on selection of Receiver from the IDU.
Hit-Less Changeover
Hit-less changeover means that when there is a switch from one receiver to another, no errors occur.
Transmitter Changeover Conditions (Hot Stand-by only)
For the Hot-Standby application only, the Indoor Unit changes from the active transmitter to the standby transmitter if any of the failure criteria are fulfilled.
Local TX Failure
For the Transmitting ODU, either of the following conditions will cause a failure:
TX Fail (caused by either Loss of Synthesiser Lock or Loss of TX IF input to TX module)
Power Control Failure P Fail between IDU and ODU Mute Invoked Power to Outdoor Unit turned Off
Remote TX Failure
When neither of the receivers at the local station can detect the Remote TX, the following conditions determine this state. Upon detection of Remote failure, a message (I cant hear you) will be sent to the remote terminal requesting a transmit Changeover:
Radioframe unlocked No heartbeat message (Inter-Station)
HighReach (HDR5 Series) System Manual Chapter 1
Page 1-30 Issue 4 (October 2009)
Changeover Time
Changeover time is defined as the duration between the failure disturbance and the re-establishment of service following a Changeover event.
When a fault occurs, the transmitter switch over time (from detection of fault to restoring of the service) is less than 5 seconds.
Protected System Special Characteristics
Disable of Certain IDU Menu Functions Auto Mode
When the Mode of Operation is selected as Auto Mode, the user cannot Mute/Un-Mute either transmitter or place a Loopback at either the RF (Outdoor Unit) or IF (Indoor Unit) level.
Automatic Determination of the Protection Mode
The Indoor Unit determines the protection mode on the basis of the selection of transmit frequencies of the two Outdoor Units. When the transmit frequencies are identical, the unit goes to Hot-Standby mode. When the go-return frequency sets are different, the unit goes to Dual-Path mode.

NOTE: Co- and Cross-polar Channel Frequencies. Cross-polar channels refer to the channel plan offset by half the channel spacing from the Co-polar channel plan. This allows channel selection of co-located units operating on antennas cross polarised from each other (giving some cross polar discrimination) to operate within half the normal channel spacing of each other.

Introduction to Chapter 2
Chapter 2 provides the installation personnel with the information required to assemble, install and commission the HDR5 System.
Site Requirements
Before installing the HDR5 System, ensure that the installation site meets the following requirements:
a. Site characteristics are satisfactory (see Site Evaluation in Chapter 1).
b. Suitable mast (pole) used for Antenna and Outdoor Unit installation is firmly in position. Pole diameters are as follows: Integral Mounting; 0.3 m antenna: 51 to 114 mm, 0.6 m
antenna: 76 to 114 mm, 1.2 m and 1.8 m antennas: 114 mm. Separate Mounting; 1.2 m and 1.8 m antennas: 114 mm.
CAUTION
THE MAST AND THE EQUIPMENT ROOM, WHICH HOUSES THE INDOOR UNIT, MUST BE EARTHED FOR LIGHTNING PROTECTION ACCORDING TO STANDARD LOCAL PRACTICES.
Installation Overview
Installation of the HDR5 System is described under the following four main headings:
a. Installing the Outdoor Unit (ODU) and Antenna Integral Mount Installation Separate Mount Installation
b. Installing the Indoor Unit (IDU) c. Installing the IDU / ODU Interconnection Cable d. System Commissioning
To supplement the installation procedure, the following appendices are provided at the end of this chapter:
Appendix A: HDR5 External Connector Pin Details on page 2-21 provides connector pin details for the external connectors of the IDU and ODU.
HighReach (HDR5 Series) System Manual Chapter 2
Page 2-4 Issue 4 (October 2009)
Appendix B: Assembly Instruction Example for LMR400 Cable on page 2-25 provides assembly instructions for the cable and connectors.
During the installation procedure, make sure that you complete an Installation Check List (see Appendix D: Example of a Installation Check List on page 2-29).
Installing the Outdoor Unit and Antenna
General Information
The HDR ODU allows the use of two basic antenna configurations, as follows:
Integral Mounting
Integral mount antennas are when the ODU clips directly onto the rear of the antenna, with no external waveguide connections or tools required. These antennas, supplied by Tellumat, are based on the RFS range, which have been customised to allow integral mount Tellumat ODUs.
All 0.3m, 0.6m, 1.2m and 1.8m Tellumat antennas are available with vertical or horizontal polarisation selectable at time of installation. See Mount the Outdoor Unit (Integral Mount) on page 2-8 for more details.
Separate Mounting
Separate mount antennas are connected, using a co-axial cable for the 4.5GHz ODU, or flexible waveguide for higher frequencies to an ODU which is mounted using a mast or wall mount kit.
Warnings, Cautions and Notes
WARNING
WHEN POWERED UP, THE ODU EMITS MICROWAVE RADIATION. DO NOT LOOK DIRECTLY INTO THE WAVE GUIDE PORT AS DAMAGE TO SENSITIVE BODY TISSUE CAN RESULT.
862-02701 Chapter 2 HighReach (HDR5 Series) System Manual
Page 2-5 Issue 4 (October 2009)
CAUTIONS
ENSURE THAT THE POWER SUPPLY IS SWITCHED OFF (FROM IDU) WHEN REMOVING OR REPLACING THE ODU.
OBSERVE ALL PRECAUTIONS AND SAFETY PROCEDURES FOR INSTALLATION ON A MAST OR OTHER EXPOSED ENVIRONMENTS.

Configure the antenna feed for vertical or horizontal polarisation as specified by the planning documentation for the link. Pay particular attention to the selection of polarization and feed alignment instructions supplied with the antenna.
Mount the Outdoor Unit (Integral Mount)
1. Ensure antenna frequency band matches that of the ODU. 2. Remove any shipping covers from the antenna and spigot.
CAUTION
FOR MAXIMUM RELIABILITY OF THE ENVIRONMENTAL SEAL, ENSURE THAT THE O-RING IS CLEAN AND UNDAMAGED.
3. Carefully slip off the spigot adapter O-ring, wipe clean and lubricated lightly, using the O-ring grease supplied (as described in the appropriate appendix).
4. If necessary, remove any shipping plugs or protection tape from the ODU spigot hole and wipe spigot hole clean.
5. Carefully push the unit onto spigot. 6. Check ODU rotation setting for vertical or horizontal polarisation
matches the antenna, clip in and secure the four lever clips, using a diagonal pattern, i.e. left-top, right-bottom, right-top, left-bottom. The 6 to 38 GHz round ODUs indicate polarity with an arrow upwards as vertical. The 4.5GHz ODUs are always mounted with the handle upwards and the antenna feed adaptor defines the polarisation.
CAUTION OBSERVE THE POLARISATION OF THE ANTENNA AND THE ODU.
Separate Mount ODU Installation
Separate mounting is required for the 4.5GHz ODU by using the Tellumat supplied mast mounting kit (MMK). This allows the ODU to be mounted directly to a mast of between 51 to 114mm in diameter. A safety handle is supplied with the MMK for holding the ODU by the handle during mounting.
The ODU is then connected to a suitable antenna using a suitable co-axial cable with N-type connectors. Figure 2-4 shows the ODU and antenna separate mount configuration.
