Alternatively, the radio can be software configured to convey E1, 2E1 or 4E1. The radio can also be configured to bridge or route IP via a 10BaseT port. The data rates scale depending on the number of enabled T1/E1 tributaries and whether the data is being bridged or routed. The products make use of spread spectrum technology and may be operated license-free in the 2.4GHz and 5.8GHz ISM bands. The Orion 24/5825SR and Orion24/5050SR are similar radios also operating in the 2.4 and 5.8GHz ISM bands respectively. Modulation can be switched between 16 and 32 QAM with digital output scalable up to 16T1/E1 depending on the specific radio. The radios are ideal for applications such as:

Cellular/PCS base station interconnects. Telecommunications companies, cellular operators and private carriers. State Local and Federal Government communication systems. Video surveillance data distribution. Power utilities. Petroleum/gas collection companies. Rural communications. Emergency/disaster telephone service restoration. Internet distribution. The radio consists of two main parts:

An RF Unit operating in the 2.4 GHz or 5.8 GHz ISM frequency bands. This could be an MDR2400ET, MDR5800, Orion2410i, Orion5810i or an Orion 5850 unit. The units with an i suffix is 1U Indoor RFUs. A Digital Indoor Unit, available with a Telecommunications (0 to 16T1/E1 depending on the radio) interface and a Data interface (10BaseT Ethernet). This could be an MDRTE, an MDRETU (75 Ohm BNC), Orion10, Orion25 or an Orion50 (10/100BaseT) unit. All DIUs operate with the MDR2400ET, MDR5800 and Orion24/5810i RFUs. Only the Orion type DIUs operate with the Orion type RFUs. For the Orion DIUs, the numerical value in the unit name roughly resembles the maximum data capacity of the unit. Interconnection between the RF Unit and Digital Indoor Unit is achieved using a low-

cost UV-protected STP (Screened Twisted Pair: 4 pairs) data cable and a UV-

protected 2-core power cable. The split Digital Indoor Unit and RF Unit configuration is used for the lowest loss between the antenna and the transceiver, thereby ensuring optimal long-range performance. The RF Units use a Type-N RF (female) output connector for connection to a coaxial cable jumper when co-located with a 2.4 GHz or a 5.8 GHz antenna for applications where long range is required. 862-01881 Issue 13 Page 10 Orion and MDR Digital Radios The RF Unit can also be located remote from the antenna (tower base or indoor mounted). The RF connector is then connected to the antenna via a coaxial transmission line. An optional indoor rack mounting adapter is available for mounting the RFU, indoors. The system is available for use in FCC regulated countries. Model variants Table 1. MDR24/5800-SR- and Orion24/5810-

The Network Management System provides control and management of the product. SNMP support via an SNMP agent in the Digital Indoor Unit ensures open network management compatibility. Comprehensive data and RF loop-back functions ensure that the system is easy to install and maintain. 862-01881 Issue 13 Page 11 2 Technical Description 2.1 System Overview Orion and MDR Digital Radios A digital radio link (DRL) consists of a pair of MDR / Orion radio stations. MDR2400, MDR5800 or Orion 5850 OU MDR / Orion IU MDR2400, MDR5800 or Orion 5850 OU MDR / Orion IU User Data User Data The radio stations consists of two main parts:

An RF Unit operating in the 2.4GHz or 5.8 GHz ISM frequency bands. The RF Unit provides the radio transceiver functionality by accepting radio link data from the Digital Indoor Unit and converting it to the 2.4GHz or 5.8 GHz ISM frequency band using spread spectrum or QAM modulation. The received signal is de-

modulated and transmitted to the Digital Indoor Unit in a digital format. A Digital Indoor Unit, available with 0, 1, 2, 4, 8 or 16 T1 or E1 data interfaces

(choice of T1 or E1 is software selectable). The Digital Indoor Unit combines nT1 or nE1 data with Wayside Service Channel serial data and link IP data to be transmitted across the radio link. The Digital Indoor Unit also provides power to the RF Unit. The E1/T1 data interface is provided through an optional removable Interface Card. Interconnection between RF Unit and Digital Indoor Unit is achieved using low cost data and power cables. 2.2 RF Unit The MDR2400, MDR5800, Orion2410i and Orion5810i RF Units make use of Spread Spectrum modulation technology for license-free operation in the 2.4GHz and 5.8 GHz ISM bands. The Orion2450 RF Unit uses three software selectable bandwidths for license-free operation in the 2.4 GHz ISM band. The Orion5850 RF Unit uses three software selectable bandwidths for license-free operation in the 5.8 GHz ISM band. The Orion2410i and Orion5810i RFUs are MDR2400 and MDR5800 RFUs respectively, that have been repackaged into 1U units that should be used in indoor unit applications only. Please refer to Appendix K for more detail. For operation, the ISM bands are divided into upper and lower frequency sub-bands. A High Band RF Unit transmits in the higher frequency sub-band and receives in the lower frequency sub-band, while a Low Band RF Unit transmits in the lower sub-band and receives in the higher sub-band. An MDR / Orion radio link will use a Low Band RF Unit on one end of the link to communicate with a High Band RF Unit on the other end. The RF Units use a Type-N RF output connector for connection to suitable 2.4GHz and 5.8GHz antennas for applications where long range is required. 862-01881 Issue 13 Page 12 Orion and MDR Digital Radios The system is available for use in FCC regulated countries. 2.2.1 Frequency plans The MDR5800, Orion5810i and the Orion 5850 RF Units operate in the 5.725 GHz to 5.850 GHz ISM frequency band with predefined frequency channel plans (termed A, B, C and D). Channel plan D is user selectable / adjustable. The MDR2400, Orion2410i and the Orion2450 RF Units operate in the 2.400 GHz to 2.4835 GHz ISM frequency band with predefined frequency channel plans (termed A, B and D). Channel plan D is user selectable / adjustable. 2.2.1.1 MDR5800 and Orion5810i Frequency Channel Plan A, B and C The channel spacing is based on the bandwidth occupied by the spread spectrum signal (approximately 17 MHz) and is used to optimise link performance.

2469 Figure 5. Orion 2450 Frequency channel plans A, B and C. 2.2.1.6 Frequency Channel Plan D (FCC Compliant) Frequency plan D allows independent control of transmit and receive frequencies. This allows a flexible frequency plan and can be used to overcome interference in the 2.4GHz and 5.8 GHz ISM bands. The frequencies that can be used in the lower or upper sub-bands can be selected in 1 MHz increments. Performance degradation can be expected when operating using channel plan D mode with the chosen frequencies close to the sub-band edges i.e. a choice of one of the high frequencies in the lower sub-band and one of the lower frequencies in the upper sub-band. The allocation of Channel plan D frequencies is shown in Table 4, Table 5 and Table 6.The Orion 24/5850 RF units have up to four different sets of minimum and maximum frequencies, which are determined by the data rate setting of the RFU. Only channel frequencies that are FCC compliant can be selected through the configuration software. The channel frequency ranges are programmed into the radio firmware and cannot be adjusted by the user. 862-01881 Issue 13 Page 16 Orion and MDR Digital Radios The radios ware tested and approved for FCC compliance with the frequency ranges below, see Figure 4.

The MDR / Orion is aimed at FCC regulated markets. Antenna polarization can used to co-locate multiple systems. Antenna polarization can be used to overcome interference. 3.1.1 Antenna selection The antenna type must be selected before the system is to be installed. The chosen antenna must enable the system to operate with sufficient link fade margin without excessive cost and allow the users link availability requirements to be met. The main consideration when selecting an antenna is antenna gain measured in dBi. A path loss analysis is highly recommended to determine the antenna gain needed for adequate fade margin. The table below shows antenna selection guidelines for some configurations. The distances are calculated for a 20 dB link fade margin. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that required for successful communication.

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. The 2.4 GHz and 5.8 GHz bands are not adversely affected by rain, ice or snow. 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 (see Environmental Characteristics on page 52 of this manual). Also, if masts are not sufficiently rigid, very strong winds can affect the antenna beam alignment and Outdoor equipment reliability due to wind force build-up and/or vibration of the mast-mounted equipment. 3.3 Multipath Effects The effects of multipath propagation can influence the radio. Understanding these effects will help when installing a radio link and maximise the reliability of the link. Multipath fading occurs when the receiving antenna receives not only the direct signal from the transmitting antenna but also a signal from the transmitting antenna that has reflected off the ground or nearby obstacles. The reflected signal takes a longer path to reach the receiver and acts as interference since it is not in-phase with the direct path signal. The amplitude of the interference can be almost equal to that of the direct path signal, thus degrading the performance of the link. Multipath propagation is dependent on transmit frequency and the specific geometry of the link such as antenna heights, distance between the antennas and the local terrain. To counteract multipath propagation, the installer can change the frequency at which the link operates or adjust the height of one or both of the antennas.

Interference can be avoided by careful planning of the system installation. The available methods for providing isolation from interfering radiators are the following:

Frequency diversity Antenna polarization It is recommended to scan the proposed installation areas with a spectrum analyzer prior to installation to establish the presence of interference. The spectrum analyzer feature available on the NMS / GUI may also be used. If interference is detected on the path, the GUI, via laptop connection, can be used to select a new channel plan (A, B, or C) to steer around the interferer, or to create a new custom channel plan (Plan D) to avoid the interference. SNMP network architecture, if employed, may also be used to make the frequency plan changes. The frequency spectrum should be scanned over a sufficient time period to ensure that periodic transmissions are recorded. Interferers will cause problems if their amplitudes are not more than 20 dB below the intended receive power level. A link path loss calculation should be performed to determine the expected receive power level. The procedure for selecting the optimum antenna polarization and system frequency plan is the following:

Perform a spectral analysis at each site in the link direction using a high gain antenna. Repeat the spectral analysis for vertical and horizontal polarization. Select the polarization with the lowest interfering levels as the system antenna polarization. Consult the MDR / Orion frequency channel plans as shown in section 2.2.1 and select the frequency plan that would operate in an interference-free band. Install the High Band and Low Band RF Units at the sites where they would experience the lowest interference in their respective receive bands. 862-01881 Issue 13 Page 29 3.5 Microcell Backhaul Applications of MDR / Orion Digital Radios Orion and MDR Digital Radios In applications where more than one independent and separate links, need to radiate from a central site, a number of parameters can be taken advantage of, to provide isolation and minimise interference between these links:

Frequency multiplexing Antenna polarization Choice of High Antenna Gain It is important to note that these methods only provide isolation between two radio Systems, and that power levels in the separate systems should be balanced to ensure correct operation. 3.5.1 Setting the Transmitted Power Levels To minimise interference, received power levels should be balanced between separate radio links. This means that transmit power levels should be set to provide similar levels of received power, as indicated by the RSSI values of the adjacent receivers at the central site. Power levels are easily adjusted via point and click selection utilizing the provided NMS / GUI, installed on your laptop or via SNMP network architecture. 3.5.2 Frequency Multiplexing The MDR2400, Orion2410i and Orion2450 offers three frequency channel plans, the MDR5800, Orion5810i and the Orion 5850 offers four frequency channel plans. Refer to paragraph 2.2.1 for more detail on the frequency channel plans. A radio link requires two channels (one for transmit and one to receive) to provide full duplex operation. Each radio has a high and a low sub-band, one that it uses for transmission and another for reception. Terminology definition: the High-band RF Unit of a system transmits on the higher of the two sub-bands. The Low-band RF Unit of a system transmits on the lower of the two sub-bands. A system (link) always has one High Band and one Low Band RF Unit. It is important to note that unwanted transmitted signals in adjacent frequency bands can affect other receivers operating in an adjacent band if insufficient antenna isolation is provided. A solution is to group high-band or low-band RF Units at the central site, rather than group high and low-

band RF Units together. 3.5.3 Antenna Isolation Separate links at a central site will have sufficient isolation when radio systems operate outside the radiation beamwidth or side lobes of the system antenna. The achievable isolation can be established by examining the measured radiation patterns of the system antennas. Directional isolation can be used if the antenna radiation is 15 dB or lower relative to the adjacent main beam. Antennas with high directionality will allow reduced angular separation of adjacent systems. Antenna cross-polarization isolation can be used for adjacent radio links, radiating in the same direction. Typical isolation of 30 dB can be achieved using high quality antennas. 862-01881 Issue 13 Page 30 4 Installation Orion and MDR Digital Radios This chapter describes a recommended installation procedure for the MDR24/5800, Orion24/5810i and the Orion24/5850. Before installation / departure to site 1. Carefully open all shipping boxes and look for any obvious damage that might have resulted during shipment. 2. Do an operational bench test to verify the functionality of the system. 3. Confirm that both radios have the correct IP configuration (refer to page 125, paragraph C.2) for "local" and "remote" sites.

Before installing the Orion or MDR RF Unit, ensure that a suitable mast is used for the antenna and that the RF Unit installation is firmly in position. The pole diameter must be between 50 and 102 mm or between 2" and 4". The outdoor unit type RF Unit may also be mounted indoors, utilizing an optional rack mount adapter (not included as a standard item) at the base of a tower for convenient access. However, this as not recommended as a long and expensive RF cable would then be required, compromising system sensitivity and increasing link costs. CAUTION ENSURE THAT THE POLE IS EARTHED FOR LIGHTNING PROTECTION. Install the system antenna. Follow these steps to install the RF Unit:

1. 2. Adjust the mounting bracket to be slightly bigger than the pole diameter. 3. Secure the mounting bracket to the pole. 4. Secure the RF Unit to the bracket using the screws on each bracket. 5. Connect the RF Unit to the pole electrically by connecting the earth cable or strap between the pole earth and the RF Unit earth point. 6. Connect the type-N RF output connector to the system antenna through an in-line lightning protection unit in areas with lightning activity. 7. Cover the connectors using an ultra violet protective, self-vulcanising tape. 4.3.1 RF Connection 1. The RF port is an N-type female connector. 2. The N-Type connector is used to connect to the antenna, typically using coaxial transmission line. 3. 1/2" or 5/8 coaxial cables are recommended. Coaxial cable that is 7/8 or larger can exhibit moding at 5.8 GHz and is not recommended for 5.8 GHz radios. 862-01881 Issue 13 Page 38 Orion and MDR Digital Radios 4. Do not use right angle N-type connectors with the radios: they may present high loss. 5. Do not use low quality cables. Some cable types, such as RG-8, may have too high a loss at 5.8 GHz.

The setup is done with a laptop / PC running the supplied NMS Graphical User Interface

(GUI) software. See chapter 6 for details on using the NMS / GUI. Installation Equipment Required The following tools and instruments are required for software setup and aligning the antenna:

RSSI test cable Voltmeter Wrench / spanner (see appropriate details in installation chapter depending on the antenna being used) PC with NMS software and supplied serial data cable. Binoculars (optional) used for locating the far end site. This will assist in the antenna alignment operation. GPS or Standard Compass (optional) used for locating the far end site. This will assist in the antenna alignment operation. Bit Error Rate Tester and connecting leads. Information Required 5.1 5.2 You should know:

the proposed frequency channel plan for each station. the expected receive level based on the chosen system configuration and a path loss analysis. B.1 Antenna Alignment 5.2.1 Introduction The RFU should be installed on both sites before alignment starts. Perform the following steps at both stations:

1. 2. 3. 4. 5. Switch the Digital Indoor Unit power ON. Install and run the NMS Software application. Configure the radio channel plan as required. Set the transmitted power to maximum. Perform a RF loopback test at each site before starting the alignment procedure. 5.2.2 Alignment Procedure 1. 2. 3. 4. Locate the far site and point the antenna to the antenna at the far site, as accurately as possible using binoculars or a compass. Connect the multimeter to the RSSI connector on the RFU using the supplied RSSI test cable and set the multimeter to measure volts. Check the RSSI level and refer to the figure below for received power level. Align the antenna until the maximum RSSI is attained. 862-01881 Issue 13 Page 42 Orion and MDR Digital Radios 5. 6. 7. Secure the antenna. Measure the RSSI level and record the value (see section 5.6). Compare with the value with that calculated for the link i.e. using the path loss calculation done when planning the link.

-30 dBm Average 1.333 0.047 V : MIB RSSI 54 2 dBm (see comment below) The front panel RF Link LED, the Received Signal Strength Indicators (RSSI : on NMS, via SNMP or as an Electrical signal on the RF Unit), Carrier-detect (NMS, SNMP) and Frame Lock (NMS, SNMP) indicators are available to assist with link installation and alignment. NOTE 1 The MIB lists a value representative of the received signal level in [-dBm]. This value corresponds to the signal power measured in a 200 kHz BW centred at the receive frequency of the radio. When not in spectrum analyser mode, the Orion RFU translates the measured signal power to a value corresponding to the wanted signal power in the receiver bandwidth. NOTE 2 For the MDR and Orion10i RFUs, the RSSI values displayed in the MIB are representative of the signal level measured over a 200kHz BW. Add ~20dB to the MIB value for a wanted spread spectrum signal. The NMS / GUI will do this adjustment automatically and will therefore always display the correct RSSI value. NOTE 3 Due to the technique used to calculate the RSSI level of a wanted signal, the measured RSSI level can differ from the actual value with up to 3 dB. 862-01881 Issue 13 Page 43 Orion and MDR Digital Radios Typical MDR2400 OU RSSI Voltage vs Received Signal Power I S S R e g a t l o V t i n U r o o d t u O 1.8 1.6 1.4 1.2 1 0.8 0.6

Typical Orion 5850 RFU RSSI Voltage as a function of RF input power level (note the different bandwidths) 5.2.3 Set Transmitted Power Level It is good practice to match received power levels by adjusting transmitted powers if co-located systems are being installed. This is important to avoid interference between co-located systems. An attenuator can be fitted between the RF Unit and the antenna if the power level cannot be sufficiently reduced. The dBm output at the RFU N-type connector (socket) levels are set via the NMS or using a SNMP Management application. 862-01881 Issue 13 Page 44 5.3 Software Setup Orion and MDR Digital Radios Refer to chapter 6, for setting up the following:

Payload interface. Service Channel (Wayside) serial port. Auxiliary in/out port. General link parameters. 5.4 Functional Test After completing the physical installation of the Digital Indoor Units, antennas, RF Units and the interconnection cables, you need to commission the system. This procedure describes how to set up the minimum requirements for successful MDR /

Orion system operation. 5.4.1 Link Bit Error Rate Performance Test To start : when the link is setup correctly, the RF Link LEDs on both DIUs on both sides of the RF link should be GREEN. When the link has been setup and is running error-free:

1. Clear the Digital Indoor Unit Log using Reset Button Position 2 2. Clear the Digital Indoor Unit Errors using Reset Button Position 1 Perform a link bit error rate performance test as follows:

Connect a bit error rate tester to the payload interface of the link. Run data over the link for a period of 24 hours. Record the BER. Record the LED statuses. Check the Digital Indoor Unit Packet Error Results via the NMS or via SNMP access to the Digital Indoor Unit MIB for the NMS, right-click on the antennas in the NMS for either side of the link and select the Diagnostic/Error Monitor option. Record the results by saving the data to a file. For SNMP access, use a MIB Browser and check the mdrmteRFLinkPerf and mdrmteG826 Performance groups. Record all results on a test record. See MDR / Orion Test Record, section 5.6 for an example. 862-01881 Issue 13 Page 45 5.5 MDR / Orion Installation Record Parameter Site Name Antenna Type RF cable length Lightening protection unit Unit Meters Yes/No Interconnecting cable length Meters RF Unit serial number Digital Indoor Unit serial number RF Unit earthed Digital Indoor Unit earthed Yes/No Yes/No Power Supply Volts DC/AC Performed by Date Approved by Name Orion and MDR Digital Radios Site A Site B Signature 862-01881 Issue 13 Page 46 5.6 MDR / Orion Test Record Parameter Unit Orion and MDR Digital Radios Site A Site B Frequency channel plan:

A detailed HTML-based help document can be found on the NMS installation CD supplied with new radios. 6.2 Introduction Orion XX MDR XXXX Digital Indoor Unit RF Unit The purpose of the Network Management System, hereafter called the NMS, is to allow you to configure, manage or interrogate the following primary functional elements of a Digital Radio Link:

A Digital Radio Link consists of two Indoor-RF Unit stations connected through a radio link. The Orion NMS is designed to auto-detect the radio type it is connected to and can support the following radio types:

Since the firmware and software for the MDR XXXX and the Orion XX10i RFUs are exactly the same, the NMS has no means to detect the difference between these units. The NMS will therefore always display the radio type as MDR XXXX. The NMS is a PC-based software package that provides you with a graphical interface that is used to perform on-site element management of a digital radio system. It allows you to configure, manage and interrogate the system by selecting various menus and options. The hardware as well as the software constituting the NMS is collectively called the NMS Terminal. The NMS Terminal is the principal system support equipment associated with the radio for system installation and commissioning. The NMS connects to a designated NMS Terminal port (labelled Element Manager) on the front panel of the Digital Indoor Unit, by means of a serial data interface (this cable is supplied in the DIU box). It can also connect to any number of Digital Indoor Units interconnected through an IP network. The NMS communicates with SNMP agent software that is contained in each Digital Indoor Unit. The NMS communicates with the agents software: the software enables a unit to interpret MIB (Management Information Base) commands via SNMP (Simple Network Management Protocol). 862-01881 Issue 13 Page 48 Orion and MDR Digital Radios NOTE The NMS application supplied with older MDR radios have been replaced with the Java-based Orion NMS. The older NMS does not support the Orion series radios and it is highly recommended to replace this NMS with the Orion NMS. 6.3 System requirements The following PC system requirements apply for the Orion NMS:

Win2000 & Win-XP 862-01881 Issue 13 Page 103 Orion and MDR Digital Radios B Appendix: MANAGEMENT OF THE MDR2400-SR MDR5800-SR and the Orion 5825-sr All management of the MDR and Orion products are implemented using SNMP (Simple Network Management Protocol), an open standard. The products can be managed by:

1. Standard SNMP managers such as HP OpenView or SNMPc i.e. there is Open Network Management compatibility. 2. For rapid product installation, the NMS GUI Application (hereafter referred to as the NMS-GA) provides extensive management functions on site and, via the microwave radio link, can be used to access the MDR / Orion station on the opposite side of the link. The NMS-GA is a software application that runs on a PC workstation such as a laptop or notebook computer that is connected to an MDR / Orion Digital Indoor Unit serial port (DB9 DTE) or an Ethernet connection (10BaseT DTE), both accessed via the DIU front-panel. B.1 SNMP and the MDR / Orion Use of SNMP within the product allows remote: configuration, monitoring of performance, notification of alarms and firmware upgrades via an IP-network. Within an IP network supporting routing of IP data, the radios can be supported from any remote location. The product can be accessed via the Internet if the necessary gateways are provided. A GSM/PCS modem dial-up capability provides another remote management option. The Digital Indoor Units have built-in SNMP agents and an extensive MIB (Management Information Base). The MDR /Orion product uses SNMP V1 (RFC1155, 1157). The user has access to an Enterprise MIB (obtainable though customer services) and MIB II (RFC 1213). Access to the MIB via the DIU SNMP agent is via Ethernet (10BaseT interface on the product's front panel) or PPP (RFC 1661) via the product's serial channel Element Manager port. The use of SNMP provides flexibility for operators with central equipment monitoring. It provides management access to radio configuration (all data interfaces), interface status and statistics, fault and maintenance information. SNMP security (if enabled) is ensured by using a login and password to give the user

"administrator" or "standard user" rights. The "standard user rights" option limits the ability to SET MIB variables. NOTE Secure SNMP is not longer supported. The product has threshold-based alarm generation (there is an extensive SNMP trap list with a trap filter that is adjustable via SNMP). Network access (wired or wireless i.e. GSM/PCS Modem) allows over-the-air remote firmware uploading (FTP) with a load verification (and reversion) capability. There are three principle requirements to use SNMP with the MDR / Orion Radio Stations. 862-01881 Issue 13 Page 104 Orion and MDR Digital Radios 1. A Management Station that runs a SNMP Management Software package that is installed on a networked or stand-alone PC that can be connected to an Digital Indoor Unit either using a serial connection or an Ethernet connection. From the Management station, the agents within the Digital Indoor Units can be configured or polled for information. 2. Agent: The agent accepts SNMP GET, SET or GET-NEXT commands from the Management Application software and collects or adjusts information from the Digital Indoor Unit's MIB. 3. Management Information Base (MIB): the MIB is a database that is accessed based on the OID (object ID) the SNMP Manager has chosen. The Digital Indoor Unit uses an Enterprise MIB and a standard MIB (MIB II) to store or allow access to information relevant to the MDR / Orion link. 862-01881 Issue 13 Page 105 B.2 Orion and MDR Digital Radios The MIB Elements OID (Object ID) DESCRIPTIONS Object Type Access Rights Description Object ID Object name

The Digital Indoor Unit /RF Unit Twisted Pair Data Interconnection for Version 2 hardware uses 2 twisted pair cables to convey payload and RF Unit control signals whereas Version 1 hardware uses 4 twisted pair cables. Notes :

Version 2.x firmware (can be uploaded into the Digital Indoor Unit using the NMSs Maintenance option) that can be used in Version 1.x hardware must be obtained from the product manufacturer. The file is not the same file that is used with Version 2.x hardware. Updated RSSI and Power control functionality have been added to Version 2.x hardware and firmware. Version 2.x firmware has 1. FTP upload functionality (needs to be activated via the MIB) 2. IP Bridging functionality (half and full duplex selectable via the MIB). Appropriate DIU hardware must be used. 3. Band Plan C 4. Refer to the MIB section of this manual and look for the symbol to see what MIB-

related functionality is in place/activated/planned for Version 2.x + firmware. 5. Functional RF Loopback built-in test feature. 6. Ethernet packet error monitoring and buffer monitoring added to MIB 7. E1 CRC4 payload monitoring added to MIB (only applicable for a single tributary) 8. Digital Indoor Unit PCB hardware revision added to MIB 9. Periodic reporting of RF Link packet errors (adjustable in time, defaulted to 10 minutes) added to MIB. Version 2.x NMS has 1. Ability to allow the user to connect to the Digital Indoor Unit using PPP (via a serial cable interface to the DIUs front panel Element Manager RS232 port) or via Ethernet (via the front panel RJ45 connector: 10BaseT). 2. Graphical Spectrum Analyzer display By default, firmware provided for the Digital Indoor Units does not provide a secure login feature (thereby limiting a users ability to set MIB variables). Suitably adapted firmware versions (dependent on hardware version) need to be requested from the product manufacturer to allow activation of this feature. 862-01881 Issue 13 Page 126 Orion and MDR Digital Radios MDR / ORION DIGITAL INDOOR UNIT FIRMWARE UPGRADE NOTICE MDR Version 2 hardware Digital Indoor Units are identified as having 200+ serial numbers, RF Units have 250+ serial numbers. If upgrading Digital Indoor Units to use V2.02+ DIU firmware, upgrade the DIU firmware on BOTH sides of the RF Link. Note that firmware upgrades of Version 1 MDR Digital Indoor Unit hardware do not require setting up of the PCB Issue in the MIB i.e. mdrmteIndoorUnitPCBrevision element. Upgrade to DIU firmware Version 2+ of Version 1 hardware will NOT give improved RSSI functionality. This is only achieved with Version 2 hardware or modified version 1 hardware. Full Duplex Ethernet Capability on MDR DIUs As a standard setting for mdrmteIndoorUnitPCBrevision, use MIB selection Issue_2. HOWEVER, if an appropriate Indoor PCB modification (made at the factory) has been made to allow Full Duplex Ethernet operation, the Issue_2_Mod_A selection option in the MIB MUST be used. Per trib line code selectivity on MDR DIUs MDR Digital Indoor Units that are modified to allow T1 line codes to be selected uniquely on a per trib basis are identified by a hardware version number of 2.1AT. These Digital Indoor Units must only be operated with firmware version 4.09 and higher. The PCB revision of these units should also be set to 5. Table 14 indicates the compatibility between different indoor and RF Unit types. The DIU firmware types required to provide the compatibility between different hardware types are listed in. NOTE Different Digital Indoor Unit firmware versions may be required to provide compatibility between different indoor and RF Unit types. Table 14 Indoor - RF Unit compatibility matrix.

You must always choose the IP address of the interface "closest" to you. In other words if you are using Ethernet to connect, then use the IP address of the Ethernet Interface. NOTE If you are updating the firmware on the remote unit, use the IP address of the

"overhead" PPP link - NOT the Ethernet interface of the remote unit. For example use 192.168.4.3 when uploading to the far side and using the bridging configuration. If by mistake you use the wrong address, you will create a "half-established" FTP session, and NO FURTHER SESSIONS will be permitted until the session times out after some minutes. 862-01881 Issue 13 Page 132 Orion and MDR Digital Radios Setup for Full Duplex mode on the MDR: Max Transfer Rate Follow the steps outlined below to setup the MDR radio in Full Duplex mode:

Upload the radio Firmware by following the aforementioned procedure. Full duplex Ethernet operation is supported from version 2 of the firmware. Setup default configuration of the radio to the required configuration. Refer to Section 2.3.4 for a description of the different default configurations. Ensure that the PCB revision of the DIU is issue_2_mod_a(3) by reading the following MIB element: 1.3.6.1.4.1.1316.1.1.1.2.4.15 mdrmteIndoorUnitPCBrevision. If the PCB revision is issue_2(2) the radio hardware does not support Full Duplex Ethernet mode. Disable all tributary channels to make the maximum user bandwidth available for Ethernet traffic. Enable Full Duplex mode via the MIB using element: 1.3.6.1.4.1.1316.1.1.1.4.16 mdrmteEthernetFullDuplex.

CLEAR ERRORS Apply a 1-reset to Clear the Historical errors on the Front Panel LEDs See note "Interpreting LED Status" on the checklist Apply a 2-reset to Clear the Event Log in the Digital Indoor Unit This is required if you wish to view the Event Log using a PC. Reset your BER Tester. 5. MONITOR STATUS Be sure that you know how to interpret the status of the LEDs before continuing!

See note "Interpreting LED Status" on the checklist If all is well, then:

BER Tester should run with no errors All 3 Front Panel LEDs should be green.

(The RF Link LED may flash orange without the need to worry.) If you have not connected a BER Tester, then the Payload LED will be Red, indicating LOS i.e. no payload signal. NOTE Make sure to deactivate all unused tribs to ensure that the Payload LED stays GREEN for the tribs used. That is: if only two tribs are used, but all four are active, a RED Payload LED will be indicated as the two unused tribs have LOS. Deactivating the two unused tribs through the NMS / GUI, will result in the Payload LED only indicating information for two active tribs i.e. are there a valid signals on the two tribs, regardless of the two other, unused tribs. 862-01881 Issue 13 Page 137 Orion and MDR Digital Radios J APPENDIX: 1+1 PROTECTION SYSTEM OPERATION J.1 Introduction J.1.1 System Description Signal fading on the radio link The presence of strong in-band interference Equipment failure When a single radio link is used to convey user data, any number of unexpected events may cause the link to fail resulting in user data being lost. This would require immediate corrective actions from the network operator responsible for maintaining the radio link. Since such a failure may occur at any time and possibly at a remote location, corrective actions may be very costly, both in terms of downtime and human resources. Common reasons for radio links to fail are:

One possible solution to this problem is to install a second redundant radio link that can automatically take over the function of the primary radio link. This not only reduces the downtime of the link, but also provides the network operator with the opportunity to repair the faulty link at a convenient time. This document describes the one-plus-one redundancy system that can be used with the radio products of Plessey BBW. Radio systems that are currently supported by the system are:

The remainder of this document is aimed at giving a detailed technical description of the redundancy system and the installation thereof. MDR2400-SR MDR5800-SR Orion 2410-SRi Orion 5810-SRi Orion 5825-SR J.2 Technical Description J.2.1 System Overview The functionality required to establish a protected radio link is already built into the MDR- and Orion-type Software Radios. This implies that the user can set up a protected radio link by interconnecting the equipment for two parallel radio links through a 1U protection panel and a dedicated communications cable. Each Digital Indoor Unit in a protected radio system continuously monitors the status of the radio link it uses, as well as the radio link provided through the redundant system running in parallel. Digital Indoor Units forming part of a redundant link at each end of the radio link share status information through a cable connecting the two Auxiliary ports of the Digital Indoor Units. 862-01881 Issue 13 Page 138 Orion and MDR Digital Radios Only the tributary payload data channels are protected by the redundant link i.e. there is no protection for Ethernet data. Tributary payload data is split and combined between links through a 1U protection panel that connects to the user network equipment as well as the two Digital Indoor Units used at each end of the redundant link. Although both radio links are functioning continuously, only one of the Digital Indoor Units is actively driving the tributary channels of the user network at any given time. Each Digital Indoor Unit continuously monitors the level of the Packet Error Ratio

(PER) for the radio link on which it is receiving user data. When the PER exceeds a predefined ratio of 10 consecutive seconds, the Digital Indoor Unit driving the tributary channels of the user network will signal the redundant Digital Indoor Unit to take over processing the data it receives over the radio link. The value of the PER threshold is configurable and can be changed through the Orion NMS if required. The default value is set at 30%. There is no notion of a primary and secondary link in this redundancy system. The first link to be configured successfully will start driving the tributary payload channels. Switch over will only take place when the aforementioned condition occurs. In the event where the link to which the data was switched over fails at a later stage, the system will attempt to switch the data back to the original link. NOTE 1 A situation can arise where the up- and downstream user tributary data is carried by separate radio links, i.e. link A carries the upstream data, and link B carries the downstream data. NOTE 2 Due to the architecture of the redundancy system, the process of switching over from one link to another is not hitless and user tributary data will be lost for a few seconds (< 10) J.2.2 System Configuration The block diagram in Figure 15 illustrates a typical redundancy system configuration. Note that this system is managed over an Ethernet LAN, where the two local Digital Indoor Units are connected to the LAN using a hub. It is important to note that the IP addresses for each Digital Indoor Unit should be unique. It is however possible to configure each link in the redundant system separately through the Element-Manager port of each local Digital Indoor Unit, in which case it is not necessary to assign unique IP addresses to the Digital Indoor Units. The block diagram in Figure 15 also clearly illustrates the following important interfaces:

J.2.2.1 1U Protection Panel There are two types of protection panels: a four and an eight tributary channel panel. They operate in the same way and perform the signal splitting and combination functions for the tributary channels taking part in the redundancy protected radio system. Note from Table 15: Protection Kit connector interfaces. that the Protection Kit is currently only provided in 110-ohm as a compromise to make provision for E1 and T1 mode.

The DB-25 pinouts used for each DB-25 connector on 862-01881 Issue 13 Page 140 Orion and MDR Digital Radios the patch panel are exactly the same as that of the MDR and Orion Digital Indoor Units respectively. J.2.2.2 Auxiliary port communication The two Digital Indoor Units on each side of the radio link share status information through the two relay outputs and OPTO inputs on the Auxiliary (AUX) port of each Digital Indoor Unit. Information shared by each of these:

Indication if the Digital Indoor Unit is currently driving the tributary channels on the user network The current Frame Lock status detected by the Digital Indoor Unit for the radio link it is using J.3 System functional description Each Digital Indoor Unit taking part in a protected radio link continuously monitors the PER of the radio link it is receiving tributary data over. If the PER for the link increases above the Sever Error Margin for more than 10 consecutive seconds, the Digital Indoor Unit will request the second Digital Indoor Unit to take over the driving of the tributary channels if the second Digital Indoor Unit sees a frame lock. Once the second Digital Indoor Unit has started driving the tributary channels, the first Digital Indoor Unit becomes the redundant link. The flow diagram for the algorithm that governs the protection switch-over process in each Digital Indoor Unit is illustrated in Figure 16.

(OID: 1.3.6.1.4.1.1316.1.1.1.2.2.18, Parent: mdrmteRFLinkConf), is set to 30% by default. This value is a percentage and represents the switch-over threshold for the Packet Error Ratio (PER). When the PER exceeds 30%, the switch-over will occur. The value of this MIB element can be adjusted to meet the exact user requirements. It is advisable to set the switch-over threshold on all Digital Indoor Units to the same value. J.5 System Verification Since most of the functionality of the protected system is hidden from the user, it may be difficult to monitor the status at times. It can however be determined by monitoring the MIB elements listed below. The status of the protected link can also be monitored through the Orion NMS.
