The ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios The Exalt ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios are the most advanced carrier-class point-topoint terrestrial radio communications devices operating in the 24.05 to 24.25 GHz frequency bands. These radios feature the capability to direct-mount to a properly-specified antenna, or can optionally be remote-mounted using a short flexible waveguide jumper between the radio and the antenna. The ExtendAir® (TDD) Series Direct Mount radios connect voice and/or digital data from one location to another, obviating the need for copper or fiber connectivity, or enhancing existing connectivity by providing a redundancy solution, a primary solution, and/or additional capacity. Figure 1 shows the ExtendAir® (TDD) Series Direct Mount digital microwave radio. Figure 1 000000-001 2011-08-26 Exalt ExtendAir (TDD) Direct Mount Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios The following ExtendAir (TTD) models are covered in this manual: Note: All models offer license key upgrades for 128 or 256-bit AES encryption. • • • rc24000 – configured with 27Mbps aggregate Ethernet capacity (1PoE port) – with license key upgrades for 55 and 200Mbps aggregate capacity rc24005 – configured with 27Mbps aggregate Ethernet capacity (1PoE port plus two additional Ethernet ports) – with license key upgrades for 55 and 200Mbps aggregate capacity rc2010 – configured with 27Mbps aggregate capacity and 4xT1/E1 (single PoE port) – with license key upgrades for 55 and 200Mbps aggregate capacity The ExtendAir® (TDD) Series Direct Mount radios require a clear line-of-sight and proper path clearance to achieve a high-performance, reliable connection. Perform professional path engineering and site planning before installing this equipment. The primary focus of this document is the installation and maintenance of the digital microwave radio, and assumes that path engineering and site planning has already been performed. The 240xx family ExtendAir® (TDD) Series Direct Mount radios utilize radio frequencies in the 24.05 to 24.25 GHz range. In most countries these frequency bands are considered as ‘license-exempt’ or ‘unlicensed.’ This means that virtually any user may use these frequencies freely, without paying for access, or any type of prenotification, post-notification or registration. As a result of this designation, users may also move or change these systems at any time, with significant flexibility to the location, orientation and configuration of the system. However, due also to this designation, there may be uncontrolled interference from other similar devices that occupy this spectrum. In these cases, it is up to engineering and maintenance personnel to design the system with existing and future interference sources in mind, recognizing that there is a chance that the interference conditions could be very dynamic, and outages may occur on the system as a result, and that, in some very rare cases, the system may cause interference into another system and may be required to be disengaged or modified/reoriented to eliminate the interference. If the spectrum in your country is designated as ‘license-exempt’ or similar, this does not infer that the installer may configure the system in any manner at any location. In most cases, there are regulations, or device-based conditions that limit the use of the device, such as maximum gain antenna, antenna types and maximum output power, as well as, in some cases, application limits, limited geography of use, and other unique regulations. The link design engineer and/or professional installer must determine these limitations and engineer/install the system within the confines of all local regulations. Also, it is required to examine any regulations that may apply to peripheral equipment, installation and cabling of the system that may be regulated for human safety, electrical code, air-traffic control, and other safety-related categories. In certain countries, the spectrum for this product is NOT considered to be license-exempt. In these cases, there may be additional regulatory requirements concerning the location, frequency, power, orientation, configuration, and other aspects of the system, including, in some cases, a need for link 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios registration, coordination, and fees that may apply to the system usage. Please consult your local regulatory organization(s) to determine usage requirements. In almost all cases, either for license-exempt or other designation, the product itself must be authorized for use in your country. Either Exalt or Exalt’s agent must have applied for certification or authorization to allow the sale and deployment of the system within the country. It is also possible that only certain versions or configurations of the device are allowed within a particular country. Please contact Exalt or your authorized Exalt representative for information pertaining to your country. Note: It is the (professional) installer’s responsibility to ensure that the radio system is implemented in a legal fashion. Exalt is not liable for any unsafe or illegal installations. Basic Features The ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios are intended for all-outdoor mounting and come with an indoor-mounted power injector. In some cases, the radio can be mounted indoors or in an enclosure. Depending on the configuration purchased, the associated antenna is either integrated as part of the unit or connected separately. For the integrated antenna models, the entire unit is typically mounted on a tower or rooftop mast structure, with Ethernet/Power and other optional interface cables running from the unit location, through a structure penetration, and to the power injector and connected communications equipment. For the external antenna models, the unit is typically mounted very close to the external antenna to minimize RF cabling and associated losses. Alternatively, the unit can be mounted at an easily accessible location with longer RF cabling to the antenna. Proper lightning or surge suppression devices and associated grounding are required for all connections. Figure 2 Mounting and cabling 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios The ExtendAir® (TDD) Series Direct Mount radios provide connections for a combination of the following data communication interfaces: • 10/100BaseT Ethernet (up to 3 ports, depending on model) • Up to 4xT1/E1 interfaces for synchronous voice traffic (xx10 models only) The ExtendAir® (TDD) Series Direct Mount radios are powered by a combined Power/Ethernet cable, and associated power injector. The power injector provides 48VDC to the unit. The power injector and/or external power supply are sold separately. The ExtendAir® (TDD) Series Direct Mount radios provide the following primary features and benefits: • Low-latency optimization and control for voice and data connections • Very high throughput and flexible interface configurations with voice+data combinations • Encryption for extreme wireless security • Easy-to-use management and configuration • Flexible utilized channel bandwidth selection for interference avoidance and frequency coordination • Flexible center frequency tuning for interference avoidance and frequency coordination • Flexible capacity to meet current connection requirements and future growth needs • Carrier-class reliability and performance • Connector covers (for weatherproofing unused connectors) 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Pre-installation Tasks This section describes the steps necessary to prepare a site for the installation of the Exalt Digital Microwave Radio. Link Engineering and Site Planning Design all terrestrial wireless links prior to purchase and installation. Generally, professional wireless engineering personnel are engaged to determine the viability and requirements for a well-engineered link to meet the users’ needs for performance and reliability. Please use the ExaltCalc path calculator, which aids in the pre-planning and engineering required to determine following attributes:: • Antenna type gain at each end of the link • Antenna mounting height/location for proper path clearance • Antenna polarization orientation • RF cabling type, length, connectors, route, and mounting • Antenna system grounding • Lightning arrestor type(s), location(s), and grounding • Radio mounting location and mechanisms • Radio grounding • Radio transmitter output power setting • Anticipated received signal level (RSL) at each end • Anticipated fade margin and availability performance at each end • Radio settings for TDD frame length and occupied bandwidth • Anticipated throughput performance (TDM circuit support and Ethernet) • Anticipated system latency With respect to radio path and site planning, these radios are generally identical to other microwave terrestrial wireless systems. Engineering of these systems requires specific knowledge about the radios, including: • RF specifications (transmitter output power, receiver threshold, occupied channel bandwidth, and carrier-to-interference to erance) • Regulatory limitations on transmitter output power setting and antenna type/gain • Noise/interference profile for the intended location Familiarization with the ExtendAir® (TDD) Series Direct Mount Radios The ExtendAir® (TDD) Series Direct Mount radios utilize time division duplex (TDD) radio transmission. This means that the transmitted signal in both directions uses the same center frequency and transmits in one direction for a period of time, and then in the opposite direction for another period 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount of time. This total period of time is referred to as the frame length or TDD frame length, and is further discussed in Time Division Duplex (TDD) Factors. The two radio terminals are identical hardware, except for the TDD setting in software. When the radios are in their default state, both radios are configured as Radio B. One end of the link must be configured as Radio A before the two ends of the radio system can communicate. It can be considered that Radio A is the primary radio in the link. Radio A provides the master clock and control to Radio B. For most applications, it is not important how the radio link is oriented, only that one end is configured for Radio A and the other for Radio B. For some applications (such as, multi-radio hub sites or repeaters), the orientation of the radio systems may be more critical. See Link Orientation and Synchronization for details. There are two ways to configure the radios for Radio A/B determination: • Use the Exalt browser-based graphical user interface (GUI) – preferred. • Connect to the radio using Telnet. Exalt recommends using the Exalt GUI for radio configuration. This interface requires a computer with an Ethernet port and web browser software, such as Microsoft Internet Explorer 5.0 or above. See Configuration and Management for details on how to connect to and use the browser-based GUI interface. Shipping Box Contents Unless purchased as a spare terminal, the radios are shipped as a complete hop (that is, a radio link pair consisting of two terminals). An outer box has labeling that indicates the contents of the box, with the part number and serial number details for both radio terminals. Inside the outer box are two identical boxes, each of these boxes is also marked with the part number and serial number of the individual terminal contained inside the box. The terminal box contains the following items: • Radio terminal (configured as Radio B) • Mounting kit (for pole or wall mounting) • Accessory kit – Grounding screw/washers – Weather-sealing tape (required for RF connectors on the rd versions) – RSL adapter cable • Registration card • Quick-start guide The power solution for ExtendAir is sold separately. For customers requiring direct 48V DC power, a power injector is available. For AC-powered applications, a POE/Adapter combination is available. Inspect the outer packaging and the contents of the boxes upon receipt. If you suspect any shipping damage or issues with the contents, contact Exalt Customer Care. Note: Register your system as soon as possible. A 2-year Warranty period applies to products registered within 90 days of purchase. The Warranty period is reduced to 1-year for unregistered products and products registered after the first 90 days. 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Outdoor-rated and shielded CAT5 cable, such as Beldon 1300A, with RJ-45 or RJ-48C connectors is recommended for the Ethernet and/or TDM connections. For Ethernet connections, a maximum length of 100 meters applies to the total length of the cabling between the radio terminal and the first network-aware connection (such as a switch or router). Initial Configuration and Back-to-Back Bench Test Every Exalt digital microwave radio goes through extensive quality testing and performance evaluation over the full operating temperature range prior to shipment. However, before installation, it is strongly advised to perform several tests and tasks that are much more difficult to perform once the radio link endpoints are distant from one another. A back-to-back bench test and pre-configuration will provide confidence that the radio link is operational and properly configured prior to installation, so that if troubleshooting is necessary, the radio hardware and configuration settings are eliminated from the troubleshooting process. Verify the following in the back-to-back testing: • • Confirm that the radio system is generally operational – Radios power-up with planned power and wiring solutions – Radio firmware version matches on each terminal (and is ideally the latest version) – Upgrade license key entry successful – RF link connects in both directions – Traffic passes across the link – Configure connected equipment and cabling – Test Ethernet (CAT5) cabling, and/or T1/E1 cabling, any auxiliary connector cabling and configure all interfaces – Configure IP settings for configuration and management – Configure passwords and security modes – Become familiar with the configuration and management interfaces through the Exalt GUI interface – Configure radio parameters – Set transmitter output power to engineered or allowed level (see RF Output Power Setting) – Set operating center frequency – Set link distance, occupied channel bandwidth, and frame length Make detailed radio performance measurements – Measure transmitter output power – Measure receiver threshold performance – Confirm unfaded error-free performance Some of these tasks may not be possible or practical within a bench test environment due to the nature of the remote connectivity of peripheral equipment. However, it is good practice to perform as much as possible in this environment to minimize field/installation time and troubleshooting efforts. Detailed performance measurements are usually not required for pre-installation, but can be easily performed at this stage and may be helpful for later troubleshooting efforts or for internal records. During troubleshooting, there may often be a point at which a back-to-back bench test should be 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount performed to verify many or all of the above items, and in the case of a suspected faulty device, to help confirm the fault and determine which end of the system is at fault and in need of repair or replacement. Note: See Back-to-back Bench Testing for detailed instructions. RF Output Power Setting The maximum RF output power is bounded by one of the following criteria: • Maximum RF output power setting capability of the radio device • Maximum RF output power allowed/authorized by the local government regulations and for this specific device • Maximum effective isotropic radiated power (EIRP) of the transmission system allowed/ authorized by the local government regulations and for this specific device • Desired RSL to not exceed the maximum RSL allowed by the device • Desired RSL to minimize/eliminate interference into neighboring systems Note: In many cases the radio must be pre-configured for legal maximum output power before connecting to the antenna and transmission system. Instructions for adjusting the output power can also be found at the rear of this guide in the EIRP section for your region. Time Division Duplex (TDD) Factors The ExtendAir® (TDD) Series Direct Mount radios are very dynamic, allowing the installer to optimize and control the performance of the radio system for the intended application. The following parameters must be carefully determined during the link engineering phase: • Link distance • Bandwidth • TDD frame size • Mode (modulation) • The setting of the above parameters determines the following performance factors: • Number of supported T1/E1 channels (on applicable models) • Ethernet throughput • System latency (delay) The following generalizations can be made with regards to these factors: • The shorter the TDD frame size, the lower the latency • The shorter the link distance, the lower the latency, the higher the throughput • The longer the TDD frame size, the higher the throughput • The higher the bandwidth, the higher the capacity • The higher the mode, the higher the capacity 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Note: Disable all T1/E1 ports if there are no T1/E1 interfaces connected. This shifts all available throughput to the Ethernet interface. Note: If a selected combination of the Link Distance, Frame Size, Bandwidth, and Mode parameters cannot support all the desired T1 or E1 ports, the ports that cannot be supported are automatically disabled. Priority is placed on the T1/E1 port number. That is, the first port to be disabled, if necessary, is the highest port number, such as Port 4. See T1/E1 Configuration Pages for more information. Link Orientation and Synchronization Link orientation refers to the Radio A and Radio B placement in your network. Link synchronization refers to using external or internal timing to coordinate multiple links. For every link, one end of the radio link must be configured as Radio A, while the other end is configured as Radio B. In single-link systems, it does not matter which end of the system is mounted at which end of the link, and there is typically no requirement for any link synchronization. Link orientation and synchronization are more important for networks with site(s) where there is more than one link of the same type or for sites using the same type of radio that are very close to each another at one or both ends. Configure collocated radio terminals for the same link orientation. That is, configure all radios at the same location as Radio A or Radio B. It can be advantageous to utilize link synchronization for collocated links. The radios allow the use of an optional GPS synchronization kit. This synchronization controls the transmitter and receiver frame timing so that collocated radios are transmitting at the same time and receiving at the same time. This can substantially reduce the opportunity for self-interference. Without synchronization, collocated radios may be transmitting and receiving at the same time, incurring near-end interference. Note: It is not always necessary to synchronize collocated radios. If antennas are substantially separated or blocked from one another and/or frequency separation tuning is used, the opportunity for near-end interference can be eliminated. Note: When synchronization is required or desired, one GPS kit is required for each r-Series radio link in the connected or collocated network. Radio A/B Configuration Use the Exalt GUI to configure the radio terminals for Radio A and Radio B orientation. Since many other parameters also need to be set, and the Exalt GUI is needed for these configurations, this is the best way to completely configure the radio terminals. Radios arrive from manufacture in default configuration, orientated as Radio B and configured as shown in Table 1. 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Table 1 Factory default settings Parameter ExtendAir® (TDD) Series Direct Mount Radio Settings Link Distance <10 miles Bandwidth 16 MHz Mode Mode 1 TDD Frame Size 2ms Link Security Key 000000000000 Administration Password password User Password password IP Address 10.0.0.1 IP Mask 255.0.0.0 IP Gateway 0.0.0.0 Ethernet Interface Alarm Enabled, 100/Full T1/E1 Enabling All Disabled Note: In many cases, the system design will not be identical to the factory default configuration, and in some cases, these differences prohibit the installation of the radio. If at all possible, obtain a computer and configure the radio terminals using the browser-based GUI. See Exalt Graphical User Interface (GUI) for details. Radio Reset Use the reset function if the IP address and/or passwords are lost. Use the following steps to perform a critical parameter reset: Remove power from the radio by disconnecting the AC adapter from the power injector. Hold down RESET button on the power injector while applying power. Hold the RESET button down through the entire power cycle and monitor the DATA+POWER left LED on the power injector. Release the RESET button only after the LED is in the steady state (45 to 60 seconds). Release the RESET button. The following configurations are reset on the radio: • IP address = 10.0.0.1 • IP mask = 255.0.0.0 • IP gateway = 0.0.0.0 • Administration password = password 10 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount • User password = password • VLAN disabled Radio Synchronization The radio synchronization feature improves the performance of Exalt radios operating in the same frequency band and that are collocated (such as in repeater and hub configurations). Radio synchronization ties radio systems together to operate off of a common clock system, ensuring that all radios simultaneously transmit and receive, and thus eliminating near-field interference issues and related radio system coupling. Synchronization Modes Synchronization can be implemented using either one or multiple GPS sources, or using the radios 'Internal' clocking signal. The following general configurations can be accommodated: • GPS sync, using one GPS source (sold separately) per link. Ideal for links where the radios are not collocated on the same rooftop or tower. • GPS sync, using one GPS source (sold separately) to drive timing to multiple collocated links, using one or more sync distribution accessories (sold separately). The ideal solution for networks that have multiple links at one location, but also have more nearby radio links that are not collocated, including repeaters and multi-link backbones. • Internal sync, using one radio to synchronize another collocated link. This can be accomplished with a simple cable and proper radio configuration, and ideal when only 2 radios are collocated. • Internal sync, using one radio to synchronize to multiple collocated links. This can be accomplished with one or more sync distribution accessories (sold separately). The ideal solution for networks that have multiple links at one location and do not have other nearby links or repeaters and multi-link backbones. Virtually any combination of hubs and repeater sites, star configurations, and/or backbones can be implemented with synchronization. It is typically necessary or ideal in each configuration to match the following parameters on every radio in the network: • Link Distance – Match to the longest distance link in the network. • Frame Length – Match to the lowest frame length to optimize total system latency (for example, for TDM networks) or match to a highest frame length to optimize user throughput. Choose an intermediate value to compromise between latency and throughput. • Mode – It is desirable, but not always necessary, to match the mode for all collocated links. • Bandwidth – It is desirable, but not always necessary, to match the bandwidth for all collocated links. For complex networks, an Exalt engineer should review multi-link networks before deployment as several factors can optimize the network for desired performance. Note: When GPS Sync is enabled, link initiation typically takes 1 to 3 minutes to allow for the radio to properly synchronize to the available GPS satellites. Figure 3illustrates two separate radios benefiting from synchronized GPS sources. 000000-001 2011-08-26 11 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Figure 3 Synchronized GPS sources Figure 4 illustrates the recommended synchronization method for two links that share a common site at one end of each link. Using internal sync, a cable can be connected between the two radios to accomplish sync. No GPS receiver is required. This approach cannot be used for more than two collocated radios. Figure 4 Internal Sync for two collocated radios When more than two radio links terminate from the same site, use the sync distribution accessory, ExaltSync Collocation Kit (sold separately) to connect more links to the Internal Sync source, as shown in Figure 5. Use one kit to connect one Sync Source radio to up to three additional links. Each additional kit expands up to three additional links. 12 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Figure 5 Internal Sync for more than two collocated radios This approach can also be used using an Exalt GPS source for synchronization, instead of Internal Sync, as shown in Figure 6. This approach is recommended if there are other nearby sites that are not collocated or part of the connected network that need to be synchronized. Using one kit, a single GPS Antenna can synchronize up to 4 collocated links. This can be expanded 3 additional links per additional kit. Figure 6 GPS Sync for more than one collocated radios At the far end of a synchronized link, if there are additional links to synchronize, use the Sync Out port of the Radio B to drive synchronization to the collocated radios. If there is only one additional radio, connect a cable from Sync Out to the Sync In port of the next radio, which should be configured as Radio A. Set this radio in the chain to Sync Recipient, as shown in Figure 7. If more than one radio is located at the secondary location, to drive synchronization for multiple Radio A terminals connect a ExaltSync Collocation Kit driven from the Radio B Sync Out port. 000000-001 2011-08-26 13 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Figure 7 Synchronization for radios in a chain Offset Timing For GPS implementations, manual control of offset timing is also allowed. This provides a means to delay the synchronization signal using a user-defined offset. This is helpful when Exalt radios are near other devices operating in the same frequency band that also use a timing source, such as GPS. The timing source to the Exalt radios can be adjusted to match the other radio system timing source mechanism. Offset timing can also optimize timing intervals for repeaters and backbones. As the distance of each link results in a unique factor for speed-of-light transmission of the radio signal, a subsequent radio can be delayed in timing so that the overall synchronization of radios is precisely maintained. Offset timing can be adjusted in 1-ms intervals, from zero to the radio’s frame length setting. For example, if using a 2-ms frame length, the offset timing can be set from zero up to 1999 ms. When Sync is Lost If the primary sync source (for example, the GPS source) signal is lost due to equipment failure, a disconnected sync cable, loss of satellite link, or other condition, the radio is said to be flywheeling. When flywheeling, the radio’s clock is free-running off internal clocking and is no longer synchronized to any source. If the original sync source is restored to the flywheeling radio’s configuration, it attempts to synchronize to this signal without causing transmission interruption. When the flywheeling radio runs independently for long periods of time, the synchronization signal may be too far outside the capture range of the synchronization loop, and portions of transmission frames can be lost during this re-synchronization process. This condition is temporary and all interconnected radios will re-synchronize to the sync source, as necessary. If the flywheeling period is exceeded, the radio will stop transmitting. There is a setting for infinite flywheeling; however, long periods of flywheeling can cause interference with collocated radios. Virtual Local Area Network (VLAN) VLAN segments information in a single connection and creates multiple separate connections to secure information of one type or for one set of users from other information types or for other sets of users. Exalt’s VLAN communications implementation adheres to the IEEE standard 802.1q. In most cases, an Exalt radio acting as a Layer 2 bridge between two locations is only required to pass traffic with VLAN tagging. Without additional configuration, all Exalt radios support frame sizes in excess of 1900 bytes, which currently supports all defined VLAN packet sizes. 14 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Note: If an application only requires the transparent passing of VLAN traffic, disable the VLAN function. Some situations require Exalt radios to act upon VLAN traffic and perform any or all of the following functions: • Connect specific traffic, using VLAN tagging, to different purposes, such as management traffic to the radio’s NMS system. • Allow only traffic with specifically assigned VLANs to pass across the link, blocking all other VLANs or any non-VLAN traffic. • Allow management access only through a VLAN connection, leaving the main traffic transparent. • Allow management access without a VLAN connection, but flowing only specific VLAN traffic across the link. Link Symmetry The default configuration of ExtendAir® (TDD) Series Direct Mount radios provides 50/50 symmetrical throughput. The Tx/Rx Throughput Ratio setting enables programming different symmetry for applications where significantly higher throughput in one direction is anticipated such as for video broadcast, video aggregation, or remote server/storage WANs. Exalt does not recommend placing two links with asymmetry back-to-back in a serial configuration due to the TDD cycle of the radios. This configuration requires that one radio transmits in an overlapping time period while another radio is receiving. Physical antenna isolation and/or frequency channel spacing may accommodate this configuration. Asymmetry is, however, ideal for single-hop, multi-link hub/spoke architectures, or simply single independent links. Note: Asymmetry is only supported for a specific subset of system configurations that are optimized for typical asymmetric applications. TDD frame sizes of 2ms and 5ms are supported. The 5ms configuration maximizes the aggregate throughput of the radio for every situation. The 2ms configuration reduces latency to meet latencycritical applications, especially for multi-link and TDM circuit support. The following RF BW/mode combinations are supported for these two configurations: • 16MHz/Mode1 • 16MHz/Mode2 • 16MHz/Mode 3 • 32MHz/Mode1 • 32MHz/Mode2 • 32MHz/Mode 3 The following Tx/Rx ratios are supported for these two configurations: • 65/35 and 35/65 • 80/20 and 20/80 Note: The 80/20 configuration is not supported for 32MHz/Mode3, because the capacity of the 100BaseT interface is fully utilized at 65/35 configuration for this setting. 000000-001 2011-08-26 15 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount For example, a radio configuration of 32MHz/Mode2 with a 5ms TDD frame size supports up to 110Mbps user capacity or 55Mbps full-duplex. By selecting 80/20 on one side of the link and 20/80 on the other side, the radio allows up to 88Mbps in one direction, and 22Mbps in the opposite direction. Note: GPS sync is supported with asymmetric settings, but in addition to the other requirements for sync, all radios tied to sync must be set with matching ratios. T1/E1 is supported with asymmetric settings. However, based on the BW/mode setting (and in some cases, TDD frame size and distance), the direction with the limited throughput limits the number of T1 or E1 connections obtained. For example, the 16MHz/Mode1 setting typically supports up to 27Mbps aggregate throughput. In the 80/20 ratio configuration, one direction is limited to 5.4Mbps, which is less than 3xE1 and less than 4xT1. Since TDM connections must be symmetrical, this setting therefore limits throughput to no more than 2xE1 or 3xT1. Simple Network Management Protocol (SNMP) The Exalt radios primarily use a browser-based graphical user interface (GUI) for radio configuration and management, as described in Exalt Graphical User Interface (GUI). In addition, a command line interface (CLI) is provided for serial and/or Telnet access, as described in Configuration and Management. SNMP is often used for management of larger networks as described here. Use SNMP to manage networked devices and execute the following functions: • GET: Obtain information from the device, such as a configuration setting or parameter. • SET: Change a configuration setting on the device. • TRAP: The device proactively informs the management station of a change of state, usually used for critical alarms or warnings. One feature of the SNMP implementation is that system configuration changes do not take effect using the SET command. Instead, groups of configuration settings can be preconfigured for global change, and a single ‘Save’ (Commit) command implements all changes. When some parameters are changed, a link may drop and/or management control lost. MIB files allow many parameters to be set at once, allowing only a temporarily dropped link or management control issue. The opposite end radio can be quickly reconfigured, with little downtime for the link and management control. The save (Commit) command is similar to the Update button. Dropped links or management control issues do not occur with every parameter change. Many configuration changes do not impact traffic or management access. Exalt radios utilize SNMPv3, a high security version of SNMP, to ensure secure access to and storing of management data. The SNMPv3 security string matches the admin and user passwords. Passwords must be eight characters or longer. Some models also have legacy SNMP support for customers requiring SNMPv1 and/or SNMPv2. Note: MIB files can be downloaded on the File Transfer Page. 16 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount System Installation and Initiation Process The tasks required for radio installation and initiation are outlined in the following figure.

Mechanical Configuration and Mounting The ExtendAir® (TDD) Series Direct Mount radios are environmentally sealed units intended for deployment outdoors. The device must be deployed within an ambient temperature range as specified, and with non-restrictive airflow around the chassis. The power injector and power supply must be placed indoors or in an enclosure. Provide proper clearance for all cables and connectors attached to the device. Mounting the System The radio is typically mounted directly to the antenna. The antenna must be the proper type for this to be accomplished (see Antennas). Figure 9 Direct-mount configuration Use the following steps to direct-mount the radio: Mount the antenna with the proper polarization alignment, following the instructions provided with the antenna. Using non-corrosive silicone grease (typically provided with the antenna), grease the rubber O-ring on the antenna fitting. Inspect the waveguide slot on the radio and the antenna. The waveguide slot aligns in the same orientation. Align the radio to the antenna, slowly press the radio onto the antenna waveguide fitting until snug. 000000-001 2011-08-26 19 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Secure the mounting clips on the four corners of the radio chassis to the mating clips on the antenna, one at a time. Note: Clip two opposite corners first, then clip the remaining two corners. Use the following steps for remote-mount configurations: Mount the antenna with the required polarization orientation. Mount the ExtendAir® (TDD) Series Direct Mount radio as closely as possible to the antenna, using the remote-mount bracket (sold separately). Connect and secure the two ends of a flexible waveguide to the antenna feed and to the radio using four (4) threaded screws per end. Note: Do not over-bend or twist the flexible waveguide. If a flange adapter is required, mount the flange adapter to the antenna, not to the radio. If required, install waveguide stabilization hardware.

While RESET button is pressed: Solid when in major alarm condition (traffic affecting). Flashing when in minor alarm condition (not traffic affecting). Off when no alarm conditions are present. DATA+POWER Right Green LED Solid when proper power is applied. RESET Button There is only one external control on the ExtendAir® (TDD) Series Direct Mount radios system, a button labeled “RESET” which is located on the Power Injector. This button performs two functions: critical system parameter reset and summary alarm information. Use the reset function if the IP address and/or passwords are lost. Use the following steps to perform a critical parameter reset: Remove power from the radio by disconnecting the AC adapter from the power injector. Hold down RESET button on the power injector while applying power. Hold the RESET button down through the whole power cycle and monitor the DATA+POWER left LED on the power injector. Release the RESET button only after the LED is in the steady state (1 to 3 minutes, depending on firmware installed). 24 Release the RESET button. 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount The following configurations are reset on the radio: • IP address = 10.0.0.1 • IP mask = 255.0.0.0 • IP gateway = 0.0.0.0 • Administration password = password • User password = password • VLAN = disabled A flashing left DATA+POWER LED on the power injector indicates that alarm conditions exist on the radio. To access summary alarm information during normal operation, press and hold the RESET button. The following is status for the left the DATA+POWER LED while holding the RESET: • Solid on is a link alarm (link is down or errored) • Flashing indicates a minor alarm (does not affect traffic) Power The radio requires a DC power source within specifications. DC can be provided from a DC battery source, central lab/rack supply, or from the supplied AC adapter. Note: Read this section completely before applying power. Terminating the RF Connection Before applying power, the device’s RF connection must be properly terminated into a 50-Ohm load. If this is not performed, the radio may be damaged by simply applying power. Also, there are human safety factors to consider regarding potentially harmful RF radiation. There are a few simple means to accommodate proper termination: • Connect a waveguide/coaxial adapter and 50-Ohm coaxial termination device to the RF port of the radio. The termination must be rated to 1W (or more). • Connect the complete transmission system. That is, the waveguide and the antenna. The connected antenna provides a proper termination for the RF output. Optional AC Power The optional AC power injector kit easily connects to the customer-supplied CAT5 PoE cable. Refer to the input voltage requirements stated on the label affixed to the adapter to ensure that the adapter can be used with the AC mains supply. The AC plug outlet provided with the adapter may need to be replaced to match the country configuration. The adapter cable uses a standard connector for this cable for use of a pre-wired cable appropriate to the outlet configuration. If the appropriate cable is not available, the existing AC plug end can be severed and a replacement plug affixed. Consult a qualified electrician for this activity. Do not plug the adapter into the mains power. First, verify that the RF connector is properly terminated (see Power), and then plug in the radio-side connector from the AC adapter to the radio. If the AC mains can be turned off using a switch, disable the power, plug the AC side of the adapter into the AC 000000-001 2011-08-26 25 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount mains socket, and then enable power to the circuit. If the AC mains cannot be turned off, plug in to the AC main socket to apply power. Verify that the radio is active by observing LED activity on the injector and radio. All LEDs on the radio flash at initial power cycle. Exalt strongly recommends that the AC mains supply be fused or on a separate breaker to ensure against over-voltage and/or over-current situations and to provide some form of protection to the radio electronics and other devices connected to the same supply. In addition, if the AC power is subject to significant spikes or variation, power conditioning is a worthwhile investment, as the quality of mains power may have a direct impact on the device operation, performance and/or reliability. An Uninterruptible Power Source (UPS) or other form of battery-backed system protects against brownout and black-out conditions, and condition the power presented to the adapter. Evaluate the opportunity for lightning or other similar surges to be present on the powering system, including the ability for surges to couple to the power wiring system. If an evaluation indicates that there is a potential likelihood for these conditions to occur, additional surge protection is recommended for the input power wiring, especially to protect the radio electronics between the adapter and the radio’s DC input connector. The above statement is similarly true for every wired connection to the device. While the configuration for surge suppression or line conditioning is of a different type for each kind of signal interface, the opportunity for damage to the device, loss of communications and property is significant. In some cases, there can also be a risk to human life by not protecting against lightning entering a building through wiring or improper grounding. If you do not have experience in this type of installation practice, consult a qualified electrician and/or telecoms professional during the installation and wiring of the equipment. Optional DC Power Injector The ExtendAir® (TDD) Series Direct Mount radios use a power injector (sold separately) to send DC power to the radio over the CAT5 cable, and including the Ethernet connections. Figure 15 shows the power injector connectors that connect the AC adapter (included with the system) and the radio. Figure 15 Power injector connectors Connect the network Ethernet connection to the DATA connection of the power injector. Connect the cable for the radio to the DATA+POWER connection of the power injector. Ground the power injector using the grounding receptacle. The injector can also be mount wall using the bottom panel brackets. 26 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount CAT5 Lightning/Surge Protection To provide for human safety and for the safety of connected network equipment, it is highly recommended to place a weatherproof lightning suppression device at the egress point where the CAT5 cable(s) enter the building, shelter, or cabinet. To protect the radio equipment, install a weatherproof lightning suppression device near the radio for all connected CAT5 cables. For the Power/Ethernet cable, specific voltage requirements must be met. The following devices are the only devices currently recommended: • Polyphaser IXG-05 • Transtector ALPU 1101-959 • Transtector ALPU 1101-898 • Transtector ALPU-1000BT-R • Transtector ALPU-EXLT • Transtector ALPU-90v Generally, use the short CAT5 cable supplied with each radio for the short connection between the radio and the first arrestor. Use bulk outdoor-rated CAT5 cable for the longer run between arrestors, and indoor- or outdoor-rated cable with a standard CAT5 termination for the connection from the egress arrestor and power injector. If the radio arrestor is deleted from the design, Exalt resellers can supply a longer cable with the proper weatherproof connector for the connection from the radio to the egress arrestor. Apply this same method for the TDM connections. There are no special requirements for lightning arrestors. Vendors, such as Transtector and Polyphaser, offer single and multiple TDM weatherproof arrestors. Note that each connector on the radio can carry up to 2 TDM (Time Division Multiplexing) connections. Note: Use only outdoor-rated UV-resistant CAT5 cable. This cable must have an outer diameter between 0.25"/6.35 mm and 0.31"/7.87mm. Belden 1300A is recommended. Securely hand-tighten all connectors on the ODU to ensure a weatherproof seal. Reset to Critical Factory Settings If necessary, the radio terminal may be reset to critical factory settings. This may be necessary if the IP address and/or passwords for the system are not known. All other configurations are left at their current settings. If a complete default factory configuration is desired, load the Default Configuration File into the system, as described in System Configuration Page. The following parameters are configured after a reset to critical factory settings: • IP Address = 10.0.0.1 • IP Mask = 255.0.0.0 • IP Gateway = 0.0.0.0 • Administration password = password • User password = password • VLAN = disabled 000000-001 2011-08-26 27 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Antenna/Transmission System This section provides guidance to mounting and connecting the RF transmission system, which consists of the antenna, RF cabling, and RF lightning arrestors. Consult the manufacturer’s instructions for proper mounting, grounding, and wiring of these devices, and for definitive direction. These manufacturer’s instructions supersede any information in this section. See Table 6 for a list of supported antennas. Antenna Alignment Antennas must be installed at both ends of the planned link to commence precision alignment. Refer to the Exalt white paper, Antenna Alignment. The ExtendAir® (TDD) Series Direct Mount radios have an integrated antenna. Antennas are typically aligned using the radio hardware for precise alignment. However, there are many very useful tools available to aid in this process, inclusive of devices specifically designed for the purpose of aligning antennas. Some examples are: • XL Microwave Path Align-R • Teletronics 17-402 Use of these devices may be extremely advantageous as compared to using the radio, because they employ many unique facilities to aid in this process. Using these tools also makes it possible to align the antennas before the radio equipment is delivered. However, many installers successfully use the radios as the means for antenna alignment. The following are the primary facilities when using the radio to align the antenna: • RSL voltage connection using a volt meter (recommended) Insert the included adapter into the GPS connector on the radio housing and the opposite end connected to a volt meter. The RSL test point DC voltage is inversely proportional and numerically calibrated to the received signal level. The voltage rises as the antennas are less in alignment, and falls as antennas are more in alignment. The voltage measurement corresponds to the received signal level in measurements of dBm (a negative number for RSL measurements). For example, an RSL of -60dBm yields an RSL voltage measurement of 0.60VDC; an RSL of –45dBm measures 0.45VDC. • Audio alignment buzzer Enable the audio alignment buzzer through the Exalt GUI. When enabled, the radio enclosure emits a sound. The pitch rises when higher (better) levels of RSL are achieved. Align the antennas until the highest pitch is accomplished. The tone is continuous when the two ends of the radio system are in communication. Otherwise, the buzzer beeps. • 28 Exalt GUI RSL reading indicates the current RSL in dBm. 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Note: There is a slight delay in RSL readings in the GUI as the RSL levels change. In this case, fine alignment can be done in small adjustments allowing a small gap of time so that the impact of the adjustment on the GUI display catches up to real time. Note: Only use the browser-based GUI for antenna alignment if there are no other means available. If this method is required, refer to Exalt Graphical User Interface (GUI). The RSL reading can be read on a PC or any handheld computing device that supports an HTML browser and Ethernet connectivity. 000000-001 2011-08-26 29 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Configuration and Management This section describes the command line interface (CLI) and Exalt graphical user interface (GUI). Telnet into the Command Line Interface (CLI) Use a Telnet connection to access the CLI in the Exalt Digital Microwave Radios. Use the CLI to set key parameters on the system. Connect to the Radio in a Telnet Session Make the Telnet connection to the radio through the Ethernet port. Use Windows and perform the following steps: Open a command prompt or MS-DOS prompt (Start>Run). Type C:\>Telnetat the command line: The default IP address is 10.0.0.1 Note: The accessing computer must be on the same IP subnet as the radio. If the radio has DHCP enabled on the PoE port (see Ethernet Interface Configuration Page), which is the default setting for a radio shipped from Exalt, and your computer's Ethernet port is set for DHCP addressing, the radio will configure your computer to 10.0.0.2, and no manual IP configuration is required for your computer. Telnet Use Telnet when prompted to enter the administration level login and password. The default administration login is admin and password is password. It is recommended that the default administration password be reset by performing a radio reset (see Reset to Critical Factory Settings). Figure 16 shows the three menu choices available after log in. Figure 16 CLI main menu 30 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount The following selections can be made on all screens: • 0 = back to previous screen • 9 = help • Ctrl+\ (control and backslash keys) = exit session Exalt Graphical User Interface (GUI) The Exalt GUI is the primary user interface for configuring and troubleshooting the radio and radio system. A computer or hand-held device with a conventional HTML browser and Ethernet port is required. Microsoft Internet Explorer is the preferred browser. Netscape, Mozilla, and Firefox are also supported. Preparing to Connect If the radios are new, both radios are preconfigured as Radio B, and have the same IP address. The initial priority is to configure one radio to Radio A and assign different IP addresses, unique to each radio. There are two ways to change the IP address: Reset the radio to the critical default factory settings (see Radio Reset). Connect to the GUI using the default IP address (10.0.0.1), and change the IP address through the GUI interface. Note: To connect to the radio’s Ethernet port and use the GUI interface, the accessing computer must match the radio’s IP address subnet. It is therefore necessary to either change the radio’s IP address through the CLI to match the subnet of the computer, or change the computer’s IP address to match the subnet of the radio (such as, a computer IP address of 10.0.0.10 if trying to connect to a radio set to the factory default IP address of 10.0.0.1). If the radio has DHCP enabled on the PoE port (see Ethernet Interface Configuration Page), which is the default setting for a radio shipped from Exalt, and your computer's Ethernet port is set for DHCP addressing, the radio will configure your computer to 10.0.0.2, and no manual IP configuration is required for your computer. To configure a radio as Radio A, connect to the GUI and change the configuration, as discussed in this section. Make Connections It is recommended that one radio at a time be configured, on a bench, before taking the radios to the field for installation: • (rc models only) Terminate the RF connector with a 50-Ohm termination or a fixed attenuator of at least 20dB (see Power). Note: Do not connect the radios in a back-to-back configuration. If the radios are set to their factory default settings, both radios are configured as Radio B and cannot communicate. Both radios also have the same IP address, which causes IP address conflicts Note: The IP address subnet of the accessing computer must match the radio’s IP address subnet to connect using Ethernet. 000000-001 2011-08-26 31 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Once connected to the radio using Ethernet, log in to the Exalt GUI. Log In Use the following steps to log in to the Exalt GUI. Open a browser window. Microsoft Internet Explorer is the recommended browser. Netscape, Mozilla, and Firefox are also supported. If there are issues with your browser, please report it to Exalt Customer Care. You may be required to use a different browser to immediately overcome issues. Type the IP address of the radio in the address bar. Figure 17 Initiating the browser connection The following window displays after pressing the Enter key or clicking the Go button in the browser window. Figure 18 Browser Login screen Login Privileges There are two levels of login privileges: • Administrator (admin) – assigned complete permissions to view, edit, and configure • User (user) – assigned limited, view-only permissions with no edit or configuration rights The default login names and passwords are as follows: Table 4 Default login information Privilege level User name Default password Administrator admin password User user password 32 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Administrator login credentials are required for configuration purposes. Type the user name and passwords for Administrator level and click OK. The following screen displays. Figure 19 Radio Information page Quick Start To establish a link on the bench, apply the following basic configurations to the radio terminal. Use the steps in the Quick Start Guide included with the radio. A summary of the items that need to be configured are: • • • Radio IP address for each end. – Each end must have a different IP address and cannot match the accessing computer’s IP address or any address assigned if radios are part of a larger network. – It may be required to change the IP address of the accessing computer after changing the IP address of the radio so that the IP subnet matches. – The radio IP address is listed on the Administration Settings Page. Install the Regulatory Domain Key (RDK) for RDK-enabled radios only. – The radio is non-functional without the RDK. – RDK is entered on the Administration Settings page. – RDK references the unit’s serial number and the country/region where the radio will be deployed. – RDK is obtained through your Exalt Authorized reseller or distributor. Set one radio as Radio A. – The radio selected as Radio A must be configured. – Radio A/B selection is the Endpoint Identifier parameter on the System Configuration Page. – Even though both radios are set as Radio B by default, confirm this configuration on the radio intended to be Radio B. 000000-001 2011-08-26 33 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount If all other parameters are still configured at their factory default settings, the radios can now be connected back-to-back to verify that the link is communicating and perform any other desired tests. See Back-to-back Bench Testing for test information. Navigating the GUI describes each page of the GUI. Most configuration parameter settings are intuitive. The following link parameters must match at both ends for the link to communicate: • Link Security Key (Administration Settings Page) • Bandwidth (System Configuration Page) • RF Frequency (System Configuration page) • Link Distance (System Configuration page) • TDD Frame Size (System Configuration page) Note: Changing any of these parameters causes a temporary loss of link. The GUI displays a warning and provides an opportunity to cancel changes. Navigating the GUI The GUI provides the primary interface for all configuration and management. There are three sections of the main GUI window: • Summary status information section (upper-left corner) • Navigation panel • Main window SUMMARY STATUS NAVIGATION PANE MAIN WINDOW Figure 20 Exalt GUI window description Summary Status Section This section of the Exalt GUI provides a review of the system status. In the screens in Figure 20, the top bar illustrates the alarm condition of the link. The information inside the bar is equivalent to the entry of the Link Name set by the administrator in the Administration Settings Page. 34 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount The color of the panel indicates alarm status: • Green indicates the system is communicating and all functions are normal • Yellow indicates a minor non-traffic affecting alarm condition • Red indicates a major traffic affecting alarm condition The left panel summarizes the alarm conditions of the local radio (the radio that matches the IP address). The information displayed is the IP address and the endpoint identifier (Radio A or Radio B). The right panel summarizes the alarm conditions of the remote radio (the radio linked to the local radio). Note: The ‘local’ radio might be the near-end or the far-end radio, depending on the management interface connection. The terms local and remote refer to the orientation of the radio terminals relative to the IP address you are managing. When making certain changes to a near-end radio without first making changes to the far-end radio, the link may become disconnected unless configuration changes are reverted to their original settings. When making changes that may disrupt the link, always change the far-end radio first, and then the near-end radio to match. The Summary Status Section allows the Exalt GUI to be a rudimentary management system. Minimize the browser window to display just the top bar or the top bar and radio information, and open several browsers on the desktop. When a window status changes to yellow or red, you can quickly maximize that window to determine the issues. Figure 21 Summary status information Navigation Panel In the navigation panel, pages with sub-pages have a plus (+) to the left of the page link. Click the plus sign or page name title to view sub-page titles. The pages can be collapsed to hide the sub-pages when a minus (–) sign appears to the left of the page link. Management pages are indicated with an X to the left of the page name. Click the X or page name to display the page within the main window. 000000-001 2011-08-26 35 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Note: The ‘local’ radio might be the near-end or the far-end radio, depending on the management interface connection. The terms local and remote refer to the orientation of the radio terminals relative to the IP address you are managing. When making certain changes to a near-end radio without first making changes to the far-end radio, the link may become disconnected unless configuration changes are reverted to their original settings. When making changes that may disrupt the link, always change the far-end radio first, and then the near-end radio to match. 36 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Radio Information Page This page provides general information about the local radio terminal. This information is helpful for troubleshooting and for record keeping. Figure 22 Radio Information page 000000-001 2011-08-26 37 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Administration Settings Page This page allows contains general parameters for the radio system. The Current Value column lists entries actual settings. Desired changes are entered in the New Value column. After all desired changes are entered, click the Update button to accept and enable changes. Figure 23 Administration Settings page Most entries on this page are self-explanatory. The following lists unique or important parameters. • Fill in the date and time fields as soon as practical. Events are captured with time/date stamps, which is valuable information for troubleshooting. • Set the Link Security Key to something other than the factory default setting (12 characters, all zeros) at each end. The link security key must match at both sides of the link. If the security key remains at the factory setting, the radio link is open to sabotage by a party with the same radio model. Each link should have a unique security key. If using the same security key for every link in the network, the radio could link to any other radio with the same security key. This is problematic in multi-radio networks. – 38 Note that the security key must be exactly 12 characters. Any printable ASCII character can be used. The link security key is case sensitive. 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Note: Changing the link security key interrupts transmission until the opposite end is changed to match. Always change the far-end radio first, and then change the near-end radio. – Reset the admin and user passwords. These passwords should not match. If the admin password remains at the factory default setting, it provides an opportunity for random reassignment by a network-connected user. – The new password must be entered twice. If the passwords do not match and the Update button clicked, the password is not changed and remains set to the previous password. • Enter the license key provided by Exalt to access extended features or diagnostic capabilities. Click Update to accept the changes and enable the new features. License keys are issued by radio serial number, so ensure that the license key used was issued for this particular radio. • For some models, the Regulatory Domain Key establishes the frequency bands, tuning frequencies, bandwidths, output power and Dynamic Frequency Selection (DFS) requirements, in accordance with the regulations that apply in the country where the product is deployed. The RDK must be typed in to enable ANY functionality for the radio. The RDK is issued to the Exalt Authorized distributor or reseller, and is paired to the specific serial number of the radio. • AES Advance Encryption Standard) can be implemented to provide additional data security for the wireless link. This function requires an upgrade license key (purchased separately). Both radios in the link must have a valid AES upgrade license key to implement AES. Different bit-length encryption license keys (for example, 128-bit and 256-bit) are also available, depending on model type. If the required upgrade license key is present, simply insert a matching ASCII string on both terminals and select the Enable AES On option for AES encryption. Note that similar to the administration and user passwords, the AES string must be entered twice for each terminal. 000000-001 2011-08-26 39 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Simple Network Management Protocol (SNMP) Configuration Use SNMP to manage networked devices and execute the following functions: • GET: Obtain information from the device, such as a configuration setting or parameter. • SET: Change a configuration setting on the device. • TRAP: The device proactively informs the management station of a change of state, usually used for critical alarms or warnings. Figure 24 SNMP Configuration page One feature of the SNMP implementation is that system configuration changes do not take effect using the SET command. Instead, groups of configuration settings can be preconfigured for global change, and a single ‘Save’ (Commit) command implements all changes. When some parameters are changed, a link may drop and/or management control lost. MIB files allow many parameters to be set at once, allowing only a temporarily dropped link or management control issue. The opposite end radio can be quickly reconfigured, with little downtime for the link and management control. The save (Commit) command is similar to the Update button. Dropped links or management control issues do not occur with every parameter change. Many configuration changes do not impact traffic or management access. ExtendAir radios utilize SNMPv3, a high security version of SNMP, to ensure secure access to and storing of management data. The SNMPv3 security string matches the admin and user passwords. Passwords must be eight characters or longer. The SNMP MIBs are organized similar to the GUI. Become familiar with the GUI before using the SNMP function. SNMP v1/v2c/v3 Support Options Enable the SNMPv1/v2c options to allow entering read and read/write community strings. 40 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Note: Users are encouraged to avoid enabling SNMPv1/V2c support due to known security loopholes in these protocols. Enable the SNMPv3 options to allow entering read and read/write user names and passwords. These entries are de-coupled from the standard radio user names and passwords. SNMPv3 provides full management security. SNMP Traps SNMP traps alert the central network management system with important issues about the radio system. Trap filters are set on the Traps Configuration page (). Not all i-Series radios support SNMP traps. Consult the release notes for more information. Trap support for all versions of SNMP are provided and can be independently enabled. Enter the IP address to which the traps are directed in the Trap Destination IP Address field. The AUX port (or the MAIN port when using in-band management) must be connected to the network to allow trap information to reach the designated IP address. In a bridged network, this may not require special network settings. In a routed network, the connected router must have a defined path for the IP address. Figure 25 Trap Configuration page Note: The Update button must be clicked to save any changes to this page. The following traps are available: • Authentication Trap: This is an SNMP standard trap when password information for SNMP is incorrect. This can help identify unwanted intrusions into the management system and for diagnosis of SNMP issues for valid users. • Radio Reboot Trap: This trap is sent after any radio reboot to inform the manager of the reboot status. 000000-001 2011-08-26 41 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount • Local/Remote Link Status Trap: This trap is sent when Link is in errored state (equivalent to the Link LED on the radio front panel or the Link status bar in the upper-left of the Exalt GUI window). • Local/Remote Status Trap: This trap is sent when Status is in errored state (equivalent to the Status LED on the front panel or the radio status box in the upper-left of the Exalt GUI window). • Local RSL Status Trap: This trap is sent when the local RSL drops below the value set in the Threshold Value (dBm) field. Buffers are provided so that continuous traps are not sent if the RSL is bouncing near the set threshold value. This trap is reset only if the RSL rises to 3dBm above the set threshold value and then drops below that value. Exalt recommends that this trap be set to a value 5dBm or 10dBm above the threshold as a warning that the system has faded and may be approaching an outage. • Temperature Status Trap: This trap is sent when the internal temperature reaches the warning point. This conveys that the external temperature control is in a fault state. Buffers are applied to this trap to avoid multiple traps when the temperature remains near the warning point. 42 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount File Management Pages File Transfer Page This page allows the administrator to upload and download files to and from the radio. Three types of files can be uploaded: configuration, radio firmware, and Regulatory Domain Database (RDD). When uploading Configuration Files, current configuration parameters are immediately overwritten, and the unit automatically reboots. When uploading radio firmware files, the file is placed into reserve memory space. After the new radio firmware file uploads, use the File Activation page to enable the files (see File Activation Page). Figure 26 File Transfer page Note: Issues with the RDK may be caused when the Regulatory Domain Database (RDD) is not up to date. Go to the Exalt Web site to download the current RDD. Up to four types of files can be downloaded: configuration, radio firmware, radio event log, and MIB. The MIB file refers to the Management Information Base related to the Simple Network Management Protocol (SNMP) function, and is only available on models which support SNMP. See Simple Network Management Protocol (SNMP) for more information. 000000-001 2011-08-26 43 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Note: Check the File Activation Page before uploading radio firmware files. New file uploads overwrite the secondary file location. If important files reside in the primary or secondary file location, download them before uploading the new files. Only the active radio firmware file can be downloaded. Therefore, to download the reserve file, it must first be activated (using the Swap button). See File Activation Page. The current radio firmware and RDD versions can be viewed on the Radio Information Page. Use the following steps to download a file. Select the type of file to download (configuration or radio firmware). Click the Download button and wait for the radio to prepare the file for download. For the MIB file download, a second page/link appears (Figure 27). Left-click the link on the page to download the file to a desired location. Figure 27 File Transfer page—download file link File download and upload is useful when configuring several radios with similar settings. A copy of the configuration file can also help restore radio settings. In addition, a copy of the Exalt default configuration file is helpful to restore the radio to factory settings. Note: Do not change the name of any download file. The configuration file must be named config.nv. To keep track of multiple configuration files, use a folder naming system or temporarily rename the file, however, it must be named config.nv before it can be uploaded to a radio. Never change radio firmware file names under any circumstances. If copying the same configuration file into multiple radios, some parameters will match and that may be undesirable. However, it may be easier to change just a subset of parameters rather than every parameter. The following parameters can cause problems or confusion if they match at each of a link: • Radio Name • Endpoint Identifier 44 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount • IP Address • IP Subnet Mask • Default Gateway The following parameters can match at both ends of the link: • Link Name • Link Security Key (although each link should be different) • Admin and User passwords • Bandwidth • RF Frequency • Link Distance • TDD Frame Size • T1/E1 configurations • Ethernet configurations 000000-001 2011-08-26 45 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount File Activation Page Use this page to move stored or uploaded files for use on the radio. The page indicates which file is currently in use, and which file is available for use. Click the Swap button to place the file in the Alternative File column into the active state and move the file in the Current File column to the Alternative File column. Figure 28 File Activation page Note: In all cases, the radio reboots after a new file is selected using the Swap function. This places the radio out of service for a short time. 46 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount System Configuration Page This page contains several critical system parameters. Figure 29 System Configuration page Note: For models requiring a Regulatory Domain Key (RDK), you must enter a valid RDK to edit this page. Most entries on this page are self-explanatory. The following lists unique or important parameters. • Set the Endpoint Identifier so that one end of the link is set to Radio A and the opposite end set to Radio B. In single-link networks, it is unimportant which end is designated A or B. In multi-link networks, however, it may be important to orient the links so that at any collocation site (where there are multiple radios of the same type at the same site), all radios are set to the same Endpoint Identifier (A or B). See Link Orientation and Synchronization. Note: Changing the Endpoint Identifier parameter requires a reboot of the radio to take effect. The reboot temporarily interrupts traffic. • Set the Radio Transmit Power (dBm) parameter to the designed level. The professional installer sets this value or dictates the value of this setting to the system administrator following the system 000000-001 2011-08-26 47 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount design and local regulations. In many cases, this value must be set to a proper value to comply with legal restrictions. Improper values can result in liability to the user and/or installer. Note: Changing Radio Transmit Power may temporarily interrupt traffic. Small changes in output power do not normally interrupt traffic, but larger changes may. – Do not adjust the Radio Transmit Power parameter to a value higher than is legally allowed. – Do not adjust the Radio Transmit Power parameter lower than the link budget and fade margin can afford. Note: The link may be lost and unrecoverable through GUI control. If the link is lost due to reduction of Radio Transmit Power, travel to the radio location(s) may be required to reset the value. • Set the Bandwidth (MHz) parameter to the designed level. The value of this is determined in the design/engineering stage. The Bandwidth parameter must also match at both ends of the link. In conjunction with the Mode parameter, the Bandwidth parameter directly relates to the capacity, latency, and the number of TDM circuits supported. The transmitter and receiver bandwidth are modified using this parameter, making it critical that it be set with respect to the local RF noise and interference profile, and/or in relation to any multi-link network design. Note: Changing Bandwidth will temporarily interrupt traffic. The Bandwidth parameter must match at each end. Adjust the far-end radio first, and then the near-end radio. Changing Bandwidth changes the radio’s threshold. A narrower bandwidth has better threshold performance and improved interference immunity, therefore if changing to a wider bandwidth, there is an opportunity that the link may be lost and unrecoverable through GUI control. Check the available fade margin and interference profile to determine if the impact to threshold and increased bandwidth is acceptable to maintain the link and the desired performance. If the link is lost due to increasing the Bandwidth parameter, travel to the radio location(s) may be required to reset the value. • Set the Mode parameter to the designed selection. The value of this setting is determined in the design/engineering stage. The Mode parameter must match at both ends of the link. In conjunction with the Bandwidth parameter, the Mode parameter setting directly relates to the capacity of the system, as well as critical RF parameters, including receiver threshold, carrier-to-interference ratio, and in some cases, maximum radio transmit power. Note: Changing Mode will temporarily interrupt traffic. The Mode setting must match at each end. Adjust the far-end radio first, and then the near-end radio. Changing Mode changes the radio’s threshold, carrier-to-interference ratio, and also may have impact on the Radio Transmit Power. A lower mode has better threshold performance and carrier-tointerference ratio, and in some cases, higher output power, therefore if changing to a higher mode (for example, from Mode 1 to Mode 2), there is an opportunity that the link may be lost and unrecoverable through GUI control. Check the available fade margin and interference profile, and determine if the impact to RF performance is sufficient to maintain the link and desired performance. If the link is lost due to increasing the Mode parameter, travel to the radio location(s) may be required to reset the value. • 48 Set the RF Frequency (GHz) parameter to the designed point. The value of this setting is determined in the design/engineering stage. RF Frequency must match at both ends of the link. It 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount may be critical to set RF Frequency with respect to the local RF noise and interference profiles, and/or in relation to any multi-link network design. The frequency selection section includes the ability to select from either the complete list of frequencies (“All”) that can be tuned for the selected band and bandwidth, or, in some cases, a preselected list of non-overlapping center frequencies (“Preferred”) that Exalt determined provides the most flexible collocation opportunities for large networks of Exalt radios The frequency selection section includes a band selection button that must be enabled for the frequency band of operation for which the link was engineered. In some cases, some bands may not be selectable due to regulatory constraints. Some bands also require Dynamic Frequency Selection (DFS), based on the active RDK. DFS is automatically enabled for these bands and is selectable for all other bands. Note: Changing RF Frequency will temporarily interrupt traffic. The RF Frequency parameter setting must match at each end. Adjust the far-end radio first, and then the near-end radio. If the RF Frequency parameter is changed to a frequency with interference, the link may be lost and unrecoverable through GUI control. If the link is lost due to changing the RF Frequency parameter, travel to the radio location(s) may be required to reset the value. • DFS is automatically enabled for any band where required based on the regulations that match the active RDK. For bands where DFS is not required, it can still be selected. For DFS to operate properly, set the antenna gain figure to match the installed transmission system gain (that is, the gain of the antenna minus all losses between the radio and the antenna). Note: When DFS is enabled, the radio temporarily stops transmitting for at least 60 seconds to ensure that no radar interference is present. This is called Channel Availability Check (CAC). The DFS status displays on the Alarms Page. Once CAC passes, the radio resumes normal operation. If at any time during CAC or regular operation a qualifying radar signature is detected, the radio shuts down communications for a minimum of 30 minutes. This is the Non-Occupancy Period (NOP). Transmission only resumes after the NOP completes and then only after a successful CAC. • Set the Link Distance (miles) parameter to the range that is equal to or greater than the actual link distance. The value of this setting is determined in the design/engineering stage. Note: Changing the Link Distance parameter will temporarily interrupt traffic. The Link Distance setting must match at each end and must not be less than the actual link distance. Adjust the far-end radio first, and then the near-end radio. If the Link Distance parameter is changed to a setting less than the actual distance, the link may be lost and unrecoverable through GUI control. If the link is lost due to this situation, travel to the radio location(s) may be required to reset the value. If the Link Distance parameter setting is set to a distance unnecessarily higher than the actual link distance, the radio may have substantially reduced performance with respect to throughput and latency. • Set the TDD Frame Size (ms) parameter to the designed level. The value of this setting is determined in the design/engineering stage. The TDD Frame Size parameter must match at both ends of the link. The TDD Frame Size parameter setting directly relates to the capacity, latency, and number of TDM circuits that can be supported over the given link distance. In multi-link networks, especially where there are collocated links, it is also important to set all radios to the same TDD Frame Size setting to avoid self-interference. Future enhancement: The GPS or 000000-001 2011-08-26 49 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount internal sync function may be necessary for these networks. See Time Division Duplex (TDD) Factors and Link Orientation and Synchronization for more information. Note: Changing the TDD Frame Size parameter will temporarily interrupt traffic. TDD Frame Size parameters must match at each end. Adjust the far-end radio first, and then the near-end radio. If the TDD Frame Size parameter is set to a value that cannot be supported for the link distance, the link may be lost and unrecoverable through GUI control. If the link is lost due to this situation, travel to the radio location(s) may be required to reset the value. • • Set the TX/RX Throughput Ratio (%) parameter to program radio symmetry. The default setting is 50/50 for symmetrical, full-duplex throughput. Other throughput ratio options are 20/80, 80/20, and 65/35, 35/65. See Link Symmetry. – For asymmetric throughput, only TDD frame size settings of 2ms and 5ms and RF Bandwidth settings of 16MHz and higher are supported. – The 64MHz/Mode2 configuration does not support asymmetry due to capacity limitations of the 100BaseT interface. Set the Radio Collocation parameter to control parameters related to the GPS Synchronization feature (see Radio Synchronization). Radio Collocation parameters can be enabled when an Exalt GPS receiver is connected to Radio A or when using internal sync between two collocated radios or when using the ExaltSync Collocation kit to synchronize multiple radio links at one location. There are two additional features: – 50 Set the Flywheel Period parameter to ‘Normal’ (default) or ‘Infinite.’ This is the period of time that the radio will run on the internal timing signal if the synchronization timing signal is lost. – The Normal parameter is a time period that allows the timing signal to be recovered. The default time to wait is set between 5 and 10 min. The system then resynchronizes to the timing signal without impact to traffic. If Normal is selected and timing is not recovered within the set time period, the system stops transmitting (loss of link) until timing is recovered. This prevents self-interference to local systems, but loses the link. – The Infinite parameter allows the radio to run on the internal clock source with no limit and attempts to resynchronize with the timing source when the timing source is detected. This allows the link to continue to operate, however, if a timing signal is not detected within approximately 10 minutes, the radio may start to cause interference to other collocated systems, and other collocated systems may start to cause interference with it. If after this interval timing is restored, a temporary outage due to the resynchronization requirement may occur. – Set the Tx Timing Offset (uSec) parameter to allow the administrator to delay transmitter timing from the GPS timing pulse by a fixed time, in microseconds. This is useful if multiple GPS-synchronized Exalt radio systems are present, separated by distance, such as when using a repeater. This delay is required to offset the difference in speed-of-light between the two locations. It is recommended to add a 5uSec delay for every mile of difference in path length. For example, if there is one link with no delay, delay the link within the field-of-view of the first link on the same or overlapping frequency channel accordingly so that it is synchronized, including the speed-of-light delay between the two sites. – When using Internal timing, select the radio to be the Sync Source (master) for the other collocated radios, Sync Auto for a radio to receive sync and run indefinitely if sync is lost (this provides the same results as infinite flywheel parameter), or Sync Recipient, which disables a radio if sync is lost, but eliminates the opportunity of self-interference. 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount • Buzzer Timeout (minutes) parameter creates an audio signal for antenna alignment. Turn on the buzzer continuously during antenna alignment or preset a period of time that the buzzer will sound. If the buzzer stops before alignment activities are complete, change the selection and press the Update button or select the ON option until alignment activities are complete. • Aggregate User Throughput parameter provides information about user capacity of the wireless link, in the current configuration. The ‘new value’ column reflects throughput if changes are made to Bandwidth, Mode, Link Distance, and/or TDD Frame Size. Click the “Aggregate User Throughput” link for details on aggregate capacity. 000000-001 2011-08-26 51 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Ethernet Interface Configuration Page This page allows the administrator to set the alarm, and duplex settings of the Ethernet connection. It also allows determination of the management information for in-band (carried over the air and available from both the MAIN and AUX connectors on either end of the link) or out-of-band (not carried over the air and only available from the local AUX connector) Figure 30 Ethernet Interface Configuration page To ignore Ethernet alarms, disable the alarming of the MAIN and/or connector. Muting the MAIN connection is desirable when connected equipment senses Ethernet signaling and makes decisions (such as, spanning tree protocol enable) based on the Ethernet signal. If the MAIN connection has muting enabled, the port is muted when the link is not active. It may be desirable to disable the alarming of the AUX connector if it is not used. Set the Ethernet interfaces on the radio and connected equipment to 100/full-duplex for best performance. If the Ethernet ports are set to auto-negotiation, poor throughput performance may be a result, as well as intermittent disconnections of the Ethernet connection. When enabled, the DHCP feature provides a basic DHCP function to ease interfacing with a computer. DHCP is enabled by default. If the Ethernet port on the computer is set for DHCP addressing, on radio bootup (for up to 10 minutes) the radio provides an IP address to the computer that is one digit higher than the radio’s IP address (for example, if the radio’s IP address is 10.0.0.1, the computer’s IP address will be 10.0.02). The radio also senses any DHCP server on the network and if detected, mutes the its own internal DHCP function. 52 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount T1/E1 Configuration Pages These pages allow the administrator to selectively enable or disable the T1 or E1 circuits, one at a time. For enabled T1/E1 circuits, additional configuration, including loopback functions, are available. Disable the unused T1 or E1 so that the alarms are turned off and more throughput is allocated to the Ethernet interface. Every enabled T1 or E1 input, even if there is no T1 or E1 signal present, reduces the aggregate throughput of the Ethernet interface by roughly 3Mbps (for T1) or 4Mbps (for E1). This page toggles between T1 and E1, as required, by clicking the Set to T1 or Set to E1 button. A warning displays that a reboot is necessary, and the radio reboots if the administrator continues. This will interrupt traffic. It may be necessary to re-login to the radio after the reboot completes. T1/E1 mode self-coordinates across the link if the link is active. This means that it only needs to be set while connected at one end. In addition, enabling and disabling T1/E1 circuits also self-coordinates across the link if the link is active. If a link is not active and T1/E1 enabling is a mismatch when a link is first created, the Radio A configuration for T1/E1 enabling supersedes the settings on the Radio B configuration, and changes the settings on Radio B. Note: Certain combinations of the TDD Frame Size, Link Distance, Mode, and Bandwidth parameter settings limit the number of T1/E1 circuits that can be carried by the radio. In these cases, certain fields on the T1/E1 Interface Configuration pages are not available, starting with the highest port number. For example, for a 4x T1/E1 radio version, if only three (3) circuits can be carried, port 4 is not available for configuration and is disabled. If only two circuits can be carried, both ports 3 and 4 are not available. Increasing the TDD frame size and Mode parameters, and/or increasing the Bandwidth parameter results in an increase in the supported number of T1/E1 circuits. T1 Interface Configuration Page This page allows the administrator to enable/disable each individual T1 channel, set the Line Build Out (LBO), Line Code (either AMI or B8ZS), and AIS enabling/disabling for each input. If enabled, the radio places an AIS code on the output of the associated interface if and when the link fails or when there is no T1 signal available from the far end to provide the user at the local end. Loopback controls are also provided (see T1/E1 Loopback). 000000-001 2011-08-26 53 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Figure 31 T1 Interface Configuration page E1 Interface Configuration Page This page allows the administrator to enable/disable each individual E1 channel. The AIS can also be enabled and disabled for each input. If enabled, the radio places an AIS code on the output of the associated interface if and when the link fails or when there is no E1 signal available from the far end to provide the user at the local end. Loopback controls are also provided (see T1/E1 Loopback). Figure 32 E1 Interface Configuration page 54 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount T1/E1 Loopback Loopback is provided for any enabled T1 or E1 port. As shown in and , the choices are: • No Loopback (default) • External (local) • External (remote) • Internal Note: Only one Internal loopback can be enabled at any time. All loopback configurations control the loop at the Line Interface integrated circuit, which is the device wired directly to the front panel ports. External loopback modes are used in conjunction with an external test source. The designation of ‘local’ or ‘remote’ refers to where the loopback is occurring relative to the location where the loopback is implemented. That is, on the radio being accessed, if External (remote) is selected, this loops the signal back at the remote radio interface back towards the local radio. Likewise, if External (local) is selected, the signal loops back at the local interface towards the remote radio (Figure 33 and Figure 34). Figure 33 External (remote) loopback Figure 34 External (local) loopback When a local T1/E1 port is configured for External (remote) loopback, it is the same as configuring the remote radio for External (local) loopback. Internal loopback uses an internal test source, and sends the test source signal across the link, looped at the remote radio’s interface, returned to the local radio, and looped at the local radio’s interface back to the source. The inputs at both ends are looped back at the line level. illustrates the internal loopback function. Figure 35 Internal loopback 000000-001 2011-08-26 55 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount VLAN Configuration Page VLAN is disabled as the default setting for Exalt radios. The Exalt radios still pass VLAN and nonVLAN traffic across the link, but do not examine the VLAN traffic or act upon it. Enable VLAN using the Exalt GUI for expanded VLAN support. Note: Once a management VLAN is configured or modified and the Update button clicked, the management connection will likely be lost. The management connection to the radio must follow the configuration to the assigned VLAN. After configuring and enabling the management VLAN on the radio, reconfigure your network’s management access to match the settings on the radio. Figure 36 VLAN Configuration page VLAN configurations are maintained even when VLAN is disabled. That is, the VLANs can be configured and the configuration saved, even though they are not active until VLAN is enabled. Use the following methods to restore the management connection if a mistake was made assigning the management VLAN and access cannot be restored: Reset the radio to the critical factory defaults (see Reset to Critical Factory Settings). Connect to the Console port using a serial interface and the CLI, as described in Telnet into the Command Line Interface (CLI), and reconfigure the VLAN settings. Four VLAN configurations are provided: • 56 802.1q Block Untagged: To pass desired VLANs across the radio, they must be listed in the lower tables per their respective interfaces. All other traffic, including untagged traffic, is not passed across the link. The radio must be managed on a VLAN whose ID is set in the upper table. This management VLAN ID is available to any interface IDs listed in this lower table. 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount • 802.1q Pass Untagged: To pass desired VLANs across the radio, they must be listed in the lower tables per their respective interfaces. All other VLAN traffic is not passed across the link, and untagged traffic is passed across the link with no changes. The radio must be managed on a VLAN whose ID is set in the upper table. This management VLAN ID is available to any interface IDs listed in this lower table. • 802.1q Tag Untagged: To pass desired VLANs across the radio, they must be listed in the lower tables per their respective interfaces. All other VLAN traffic is not passed across the link, and untagged traffic is tagged with the programmed Default VLAN, per interface, as set in the upper table. Any interface requiring the default VLAN ID to pass must have the Default VLAN ID listed in the table below. The radio must be managed on a VLAN whose ID is set in the upper table. This management VLAN ID is available to any interface IDs listed in the lower table. • Management only: All traffic is passed transparently, except the radio is managed on an assigned Management VLAN ID, as programmed in the upper table. 000000-001 2011-08-26 57 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Ethernet Rate Limiting This page enables radio Ethernet port rate limiting. Enable this to limit the output information rate to at or below downstream networking equipment capabilities. The rate is in Mbps or kbps, as specified. Figure 37 Ethernet Rate Limiting page For models with more than one Ethernet port, each port can have rate limiting enabled or disabled. The default setting is disabled. Use the Update button to save changes. 58 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount GPS Information Page This page provides information on how many GPS satellites are within the view of the Exalt GPS receiver. This page is active for implementations that include the GPS receiver connection for synchronization. This information can be helpful for troubleshooting GPS issues. Figure 38 GPS Information page 000000-001 2011-08-26 59 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Alarms Page This page provides an easy-to-read summary of the alarm status of both local and remote radios. The colors on this page reflect the color of the alarms displayed on the radio front panel. However, additional detail displays on this page to aid in quick assessment of issues and status. Figure 39 Alarms page Table 5 lists alarm status conditions that appear on this page. 60 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Table 5 Alarm status indicators Label Link DFS Collocation Ethernet T1/E1 Input Temperature Status Indicates RF link status: • Green Solid = Error-free connection (BER<10e-6) • Yellow Solid = Errored connection (10e-3>BER >10e-6) • Red Solid = No link (BER>10e-3) Indicates the status of the Dynamic Frequency Selection (DFS). • Green = No DFS activity, normal transmission • Red = Either CAC or NOP is in progress. Indicates the enabled/disabled status with Internal or GPS sync and current alarm status. • Green Solid = Sync enabled and sync input present • Yellow Solid = Sync enabled and missing proper sync input in flywheel operation period • Red Solid = Sync enabled and missing proper sync input signal and flywheel period expired • Green Solid = Alarm Enabled and Ethernet Link present • Red = Alarm Enabled and Ethernet Link not present • Grey = Alarm Disabled • Green = Enabled and connection present (clocking confirmed) • Red = Enabled and no connection present • Grey = Disabled and no connection present • Green Solid = Normal temperature range • Yellow Solid = Exceeding normal temperature range The Temperature alarm monitors the internal temperature of the unit based on specific points inside the radio chassis. It is normal for the internal temperature to be above the ambient temperature, so the temperature reading may be higher than the highest specified ambient temperature. When the internal electronics reach a point that is higher than the normal temperature rise at the highest ambient temperature, the temperature alarm turns yellow. Power down the radio as soon as possible, and investigate the cause of the temperature rise before the radio is put back into service. In almost all cases, a temperature alarm is due to an external cause. 000000-001 2011-08-26 61 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Performance Page This page provides statistical information about the performance of the system in relation to the integrity of the user data and the RF link. Figure 40 Performance page • The Current BER field indicates the current bit error rate of the link. If the link is operating perfectly, this should indicate zero. Generally, the link should remain at a BER less than 1x10-6 (1 bit out of every million bits errored). This is the threshold performance specification and the standard to which the link was engineered. However, radio links can and are affected by weather, interference, and other external sources and will occasionally have a higher error rate. A link remains operational unless the BER exceeds 1x10-3 (1 bit out of every hundred bits errored). Consult the link design engineer for an understanding of the predicted error rate of the radio link as it has been designed. Many applications are unaffected by bit errors, but TDM circuits (for example, T1 or E1) are more sensitive. Also, if the link operator is providing a service guarantee, this value may need to be monitored or examined in cases of service issues. The behavior of BER in relation to other alarms or measurements and external events can be very helpful in troubleshooting activities. • 62 Current RSL is the measurement of the received signal level at the radio antenna port. This is the measured level of the RF signal coming from the opposite end of the radio link. The link was engineered to a specific RSL by the link design engineer, and this RSL should be obtained during installation and remain relatively stable during the operation of the link. RSL can and will vary as a result of weather changes and other external sources, such as path obstructions. Once again, this variation was part of the original design to achieve a certain level of performance over time. Bit errors occur when the RSL falls to a level within roughly 3dB of the threshold specification. When the RSL falls below the threshold specification, the link disconnects and will not reconnect until the RSL is above the threshold specification. The behavior of RSL in relation to other alarms or measurements and external events can be very helpful in troubleshooting activities. 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount • Errored Seconds (ES) indicates the total number of seconds that occurred where there was at least one bit error since the last time that the radio statistics counter was reset. Generally, ES are not a significant concern, so long as they are not continuous or above the anticipated performance based on the original link engineering goals. If ES are continuous or at a high rate, this is normally an indication of poor link performance due to poor RSL or interference, or severe impact by weather or other environmental factors. However, similar to the performance factors previously listed, ES can and will occur in any radio link. Once again, consult the link engineer to determine the original design goals, and compare actual performance to these expectations to determine if any improvements are necessary or if other problems may be causing excessive ES. Note: Unavailable Seconds do not register as ES. In other words, the ES counter counts all seconds that are errored NOT INCLUDING the seconds that were classified as unavailable. The total number of seconds with errors or outages is the sum of ES and Unavailable Seconds. • Unavailable Seconds (also called UAS) are similar to ES, but this counter keeps track of every second where the bit error rate equals or exceeds 1x10-3, as well as any seconds where there is a complete loss of radio communication, over the period since the last counter reset. If Unavailable Seconds are continuous or at a high rate, this is normally an indication of poor link performance due to poor RSL or interference, or severe impact by weather or other environmental factors. However, similar to the performance factors listed above, Unavailable Seconds can and do occur in any radio link. Consult the link engineer to determine the original design goals, and compare actual performance to these expectations to determine if any improvements are necessary or if other problems may be causing excessive Unavailable Seconds. • Minimum RSL indicates the worst (lowest) received signal level that occurred since the last counter reset. It is helpful to know if the RSL dropped significantly from the normal level, or has reached a level near or below threshold. • Minimum RSL Timestamp indicates the date and time when the Minimum RSL occurred. This is helpful for general troubleshooting, and especially comparing to items in the event log or diagnostic charts from the same time period. • Maximum RSL indicates the best (highest) RSL that occurred since the last counter reset. This indicates the best performance of the radio link, which is normally equal to the installed value, and is usually the designed value. • Time Since Reset indicates the amount of time passed since the last counter reset. This helps to quantify the seriousness of other statistics, such as ES and Unavailable Seconds, if there have been high numbers of ES and/or Unavailable Seconds over a relatively short period of time. All end-of-link statistics can be independently reset using the respective reset statistics button. It is good practice to reset the statistics during link commissioning (after all antenna alignment is complete and stable RSL at designed levels is achieved, and no more system reboots are anticipated). Regularly review this page to note performance and reset the statistics so that the counters can more precisely pinpoint issues. Note: Resetting statistics from one end also resets the statistics for the same radio at the opposite end. That is, if the Local statistics are reset, logging into the remote end shows the Remote statistics on that end (which is the local radio in the first condition) as being reset at the same time. 000000-001 2011-08-26 63 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Event Log Page Use this page to review a list of the events logged by the radio. The following items are listed in the event log: • Alarms • Alarms clearing (Normal) • Radio Reboots Every event is tagged with the time that the event occurred, and a severity and type. The event log also allows filtering to limit the view of the log to the lowest level of desired information. For example, a filter level of Minor displays Minor, Major, and Critical severity events. The log contains the last 1000 events. Events are deleted on a FIFO basis. The event log can be cleared and be downloaded from the radio (some models may require a software upgrade to enable this feature). A screen capture of the browser window can serve as a useful record. Figure 41 Event Log page 64 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount User Throughput Page This page illustrates the user throughput of the radio, as configured.

This page illustrates the historical (and current) performance for three parameters: RSL, Radio Temperature, and BER. The horizontal scale illustrates 120 points of time measurement and is synchronized on all three graphs. The scale displays in minutes, hours, or days from the last two hours (120 minutes), five days (120 hours), or four months (120 days). All information is stored, so all of these periods are available for short- and long-term performance analysis. The right side of a graph represents the most recent measurement, and data ‘marches’ from the right-to-left at every interval. The vertical scale of each chart independently scales to show the maximum resolution based on the maximum variation of the data over the selected time measurement. Figure 44 Diagnostic Charts page Use the cursor to point to any spot on any of the three charts, and all three charts illustrate the measurements taken for that time interval in the upper-left corner of each chart. The time interval is indicated by T=(value). This is followed by the value of the measurement, listing the highest value, lowest value and average value measured over that time interval. For example, in Figure 44 the displayed time interval is minutes, and the cursor is held at the T=17 mark on the horizontal axis. The measurements shown indicate performance from 17 minutes ago. The high/low/average values shown on each chart are measurements made across that specific one-hour interval. Changes in RSL often have an impact on BER, and this can be confirmed by looking for synchronized events. When BER events occur without corresponding changes in RSL, this normally indicates 000000-001 2011-08-26 67 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount interference, atmospheric changes, transmission system issues (such as problems with cables, connectors or antennas), or possibly radio hardware problems. It is also useful to help determine if changes in radio temperature are occurring, and if they are having any impact on RSL or BER. If the radio is mounted in an environmentally controlled location, this has less relevance. However, temperature monitoring can be helpful to ensure that the radio is operating within specifications. 68 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Spectrum Analyzer Page The spectrum analyzer feature provides a useful pre-planning and troubleshooting tool. This feature is only available on radios with firmware supporting the spectrum analyzer. Perform a spectrum analysis after deployment and just before commissioning to maintain a record of the spectrum at the time of deployment. Figure 45 shows the Spectrum Analyzer page. Figure 45 Spectrum Analyzer page While a professional spectrum analyzer provides higher levels of control and precision for preplanning, the Spectrum Analyzer page allows evaluation of the RF spectrum as seen at the radio’s RF input port prior to deployment. This is useful for pre-planning the center frequency and occupied bandwidth, and to determine polarization and antenna type and mounting locations. For troubleshooting, enable the spectrum analyzer to scan the desired segment or full band of the frequency range. Select the step size and set the remote radio transmitter ON or OFF. This allows viewing of the clean spectrum without the remote transmitter on and a comparison of the remote transmitter in the midst of other signals. 000000-001 2011-08-26 69 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Note: Enabling the spectrum analyzer interrupts all radio traffic for the duration of the analysis. In addition, access to the radio’s GUI may also be interrupted, depending on the location of the interfaced computer relative to the radio where the spectrum analysis is occurring. The GUI is available at the completion of the spectrum analysis. Use the smallest step size to obtain the finest view of the spectrum. The spectrum analyzer can be set to match the start and stop frequency for a dwell mode. Peak and average detection modes are also available. Peak detection is helpful for capturing intermittent events such as pulsed emissions. It is best to set the Scan Time option to a time value as opposed to using the ‘infinity’ setting. If your management computer is connected to the radio through the radio link, access to the GUI is interrupted during the duration of the analysis. Note: The result of selecting infinity may be complete loss of contact to that radio and may require a physical visit to the radio location to disable the spectrum analyzer. The spectrum analyzer graph displays received signals in red or green (Figure 46), normalized in dBm to the resolution bandwidth of the analyzer. Red indicates a peak hold function. This is the highest level detected during the entire scan. Green indicates the last value measured at that frequency. Figure 46 Spectrum analyzer graph example A completely green vertical box indicates that the signal maintained a steady level for the entire scan or that the last scan measured at a strong or stronger level than the rest of the analysis. A completely red vertical box indicates that there was a signal at some point during the scan, but that the signal was not detected at the last scan. A graph displaying green on the lower part and red at the upper part indicates that at some time during the scan, a signal was detected at a higher level than was detected during the last scan. The last spectrum analyzer scan performed displays in this page until the radio is rebooted. You can do a screen capture for record keeping and for comparison to future analyses. The time and date of the analysis displays on the page, which is handy as a reference in a screen capture. 70 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Ethernet Utilization Page This page shows a chart for each Ethernet interface to illustrate inbound and outbound packet utilization. This is shown as a percentage of the interface configuration (that is, if your interface is set for 100BaseT, then 100% represents 100Mbps. Compare offered load (inbound) to delivered load (outbound) to determine if radio capacity is a bottleneck for the data transfer. This chart can illustrate inbound and/or outbound utilization, and uses different colors for data entry. The legend can be hidden. Figure 47 Ethernet Utilization page Note that the outbound utilization never exceeds the rate where a radio is configured. For example, if the radio is configured for a 55 Mbps capacity, outbound utilization will never exceed 55 Mbps at 100BaseT. The watermark level function allows administrators to receive an SNMP trap when watermark conditions are exceeded. For example, if a radio is configured for 55 Mbps capacity, the administrator may wish to be warned if the radio exceeds 50 Mbps for more than 1 hour per day. In this case, set the watermark level to 50% and the trap duration to 60 minutes. Traps must be enabled for this function to be active. When the watermark level function is enabled, a line on the chart appears for data comparison to the watermark. 000000-001 2011-08-26 71 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Reboot Page Use this page to reboot the radio.

Power/Ethernet Connector This connector is the primary connector on the radio, and must be connected to provide power to the radio, and primary Ethernet communications for traffic and Ethernet. Figure 52 illustrates the pin orientation and functionality for this connector. The Ethernet connector implements Auto-MDIX, and therefore either ‘straight’ or ‘crossover’ Ethernet cables may be used, independent of the wiring of the connected device. The wiring follows typical wiring for Power-over-Ethernet (PoE), however the power consumption requirement for the ExtendAir® (TDD) Series Direct Mount radio does not allow for ‘standard’ (802.3af) PoE, and only the Exalt power injector shall be used. In addition, the Exalt power injector provides critical reset and alarm capability that would not be available from a generic PoE injector, even if the power consumption requirement is met. 78 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Pin Function Paired with Pin 2 Paired with Pin 1 Paired with Pin 6 +DC Power (48V) In +DC Power (48V) In Paired with Pin 3 -DC Power (48V) In -DC Power (48V) In Figure 52 Power/Ethernet connector 000000-001 2011-08-26 79 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios Antennas Table 6 lists antennas supported by theExtendAir® (TDD) Series Direct Mount for use in the USA.

Exalt Digital Microwave Radio systems are designed by Exalt’s expert engineers with extensive experience through multiple generations of microwave radio design. These new-generation systems contain extensive diagnostic tools, alarm indications, and troubleshooting aids. And, as compared to other systems in their class, are easier to install, maintain, and troubleshoot. The GUI provides information to aid in troubleshooting (see Diagnostic Charts Page). Contact Exalt Customer Care for further assistance with issues with your Exalt radio and with suggestions on how the radio and documentation can be improved. General Practices Troubleshooting a microwave radio link can be a complex task. Approach troubleshooting as a process of elimination, and first determine which portions of the system are operating properly. In a vast majority of cases, failures or poor performance of microwave links is attributed to something other than the microwave radio hardware. In this respect, the back-to-back bench test (see Back-toback Bench Testing) is very important to determine if radio hardware is operating properly and eliminate many variables in the troubleshooting process. If a back-to-back bench test fails, then the radio hardware is either broken or the radios are improperly configured. Upgrade the radio to the most current release of firmware, and/or reset the radio to its critical factory settings, following the quick start guide instructions and those in Configuration and Management, helps to confirm if configuration issues cause failure. The most common issues with microwave radio links are: • An improperly terminated RF cable • Multipath propagation • RF interference • Path obstruction • Misaligned antenna • Faulty antenna • Improper grounding • Insufficient link margin in the design/implementation • Moisture in the transmission system (antenna feed and/or RF cable) If the radio link has been operating without issues and is exhibiting new poor performance behavior or becomes completely inoperative, the troubleshooting process should pay close attention to any conditions that may have changed between the time when the system was working without issue and the time when the issues started. Also, it can be helpful to compare some performance parameters of the system before and after the presence of issues. Often the source of the issues can be determined by thoughtful consideration of changes, such as: • Changes in weather, including high winds • Changes made to the radio equipment, transmission system, or connected equipment • New radio systems or electronic equipment the nearby radio or transmission system 000000-001 2011-08-26 81 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios • New construction nearby either end of the link, or along the path • Tree growth, flooded fields, or changes in rivers/lakes along the path Verify that configurations are set as follows: • RF matches at each end of the link • Bandwidth matches at each end of the link • Link distance matches at each end of the link • TDD Frame Length matches at each end of the link • Endpoint Identifier is different at each end of the link (one end Radio A, one end Radio B) • Ethernet interfaces are enabled, as desired • AUX Ethernet is set for in-band or out-of-band NMS, as desired • T1/E1 enabling matches at each end of the link • Link security key matches at each end of the link Also, use the ExaltCalc tool in the design phase to determine the optimum setting for the Bandwidth and TDD Frame Length parameters for the given link distance, and provides guidance to the expected RF link performance, as well as throughput, latency, and number of supported T1/E1 circuits. Typical Indications of Issues In many cases, microwave radio users do not notice changes or degradation to the radio system until the radio system fails completely or becomes highly errored or significantly intermittent. However, regular management of the radio system can help indicate changes in performance that have not yet impacted user performance, but may impact performance at a later date if left unchecked or unaddressed. The administrator can use this as an opportunity to be proactive and monitor the radio link performance regularly, watching for unexplained or unexpected changes in performance and trends in performance changes. Most importantly, monitoring radio system RSL over time indicates the performance of the radio system. Address any long-term drop in RSL and erratic or unsteady RSL. Some RSL changes are expected and weather patterns and the related multipath can cause dramatic RSL changes resulting in system outage. However, that outage should not occur at a significantly greater rate than the designed long-term performance. Consult the path design engineer for more information about link reliability expectations and anticipated RSL deviation. In addition, regular inspection of the transmission system (RF cables and antennas) and paying close attention to changes along the path, such as construction or tree height, or new microwave radio installations nearby, can be extremely helpful and proactive. When link performance is very poor, alarms on the radio front panel and within the radio’s management system indicates particular failures. Consult this manual for more information on the specific alarms and diagnostics, or contact Exalt Customer Care for assistance. Exalt Customer Care is primarily motivated to determine if the radio hardware is faulty and require return for repair, and to help execute an effective and efficient repair and return process for radio terminals believed to be faulty. However, Exalt Customer Care provides advice regarding the total radio system and RF path engineering and environment, and advises on troubleshooting. End users should first contact the installer and/or designer of the system. In many cases, an in-depth understanding of RF design is required, and on-site analysis and special test equipment, may be 82 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios necessary. Compared to phone support from Exalt Customer Care, troubleshooting is much more expeditious if the professional installer and/or link designer examines the system and reviews the management information in the GUI. In turn, if the professional installer and/or link designer contacts Exalt Customer Care, the process to rectify the system is much more expedient due to the in-depth knowledge related to the implementation and the RF environment. Improper RF Cable Termination Improper RF cable termination is a very common problem. In many cases, this is a problem that occurs during installation and is not a problem that suddenly appears. However, if cables are moved or flexed, especially near the termination points, and radio errors, changes in RSL, or other performance issues occur, this is a certain sign of this issue. Another relatively easy method to test for this condition is to decrease the output power of the radio system (at each end, one end at a time). A poor RF cable termination may be reflecting too much RF energy back into the radio system, and reducing output power reduces the reflected energy at a faster rate than the transmitted energy towards the far end. Be careful not to reduce the output power to the point where the radio’s threshold is reached. Typically, a reduction of just 3 to 6dB is enough to determine if this is the issue. If the reduction of output power clears the error condition, this is the likely cause. Use a reflectometer or meter that can read VSWR at the operating frequency to identify poor terminations as well as poor antenna feeds. Note: The Praxsym VSWR meter is an excellent tool for this purpose. Multipath Propagation Multipath propagation is a term that encompasses changes to the RF path, such as reflections and/or refraction, causing partial or complete destruction of the radio signal, and thus excessive bit errors and/ or system outages. Rapid changes in temperature, inversion layers, humidity, air pressure, water evaporation, as well as standing water or moisture on objects along the path are all examples of changes that can cause multipath propagation. New building construction near either end of the path or along the path can cause new reflection characteristics. If your system has been operating without issue and is suddenly experiencing issues that are symptomatic of a certain time of day or related to change in climatic events or some of the external factors listed above, this is likely the cause. Consult a professional RF path engineer in these cases. Often, minor repositioning of the antennas at either or both ends can reduce or eliminate these problems. RF Interference RF interference is usually indicative of another radio system nearby either end of your radio system or aimed towards one or both ends of your radio system – usually at or near the same frequency and usually with a similar signal level. Other forms of RF interference also exist, such as electronic equipment placed close to the radio chassis or transmitters that couple onto the cabling or grounding system of the radio. Microwave ovens and wireless communication devices used near the equipment or cabling are examples of electronic equipment interference. 000000-001 2011-08-26 83 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios Note: Exalt Digital Microwave Radios operate in license-exempt bands. Microwave ovens, wireless Internet devices and cordless phone technology may also use this frequency band. It may be necessary to separate the radio chassis, cabling system and antenna from these devices. RF interference, like most other causes of problems, is indicated by significant bit errors and/or system outages. One means to determine presence of interference is the use of a spectrum analyzer that covers the same range as the radio system. A professional RF engineer can use a spectrum analyzer to locate sources of interference, measure these sources, and determine potential remedies to take to operate in the presence of interference. If a spectrum analyzer is not available, the radio’s RSL port can help determine RSL levels of interfering signals. By turning the far-end radio off, the residual RSL measured by the radio indicates the level of interference seen by the radio. It is possible that interference levels below that which can be measured still have an impact on the radio system – especially if the radio system has low fade margin or is using a high order modulation. Exalt Digital Microwave Radios provides considerable flexibility to tune to different frequencies across the bands within which they operate. This is the easiest method to use to try to avoid existing interference. In addition, the occupied bandwidth of the radio can be reduced. This, along with retuning, can be very effective, however throughput is reduced. Repositioning the antenna and/or changing polarization, or upgrading the antenna to a higher gain, and/or using a high-performance antenna, are all secondary means that can be used. It may be necessary to perform combinations of both radio changes (retuning, occupied bandwidth reduction) and antenna system changes (position, polarization, upgrade). Path Obstruction A path obstruction is defined as an object, such as a building or tree, impeding the proper path of the radio system. If the system design was proper at the time of installation and issues arise at a later date, an updated path profile and survey may be necessary to identify changes in path clearance. Misaligned Antenna At the time of initial installation, it is critical that the antennas at each end are properly aligned and that the designed RSL is achieved. However, antennas may become misaligned due to high winds, changes in the guy-wiring systems keeping the antenna mast stable, or loosening of the antenna mounting hardware. A reduction in the RSL of the link is symptomatic of this condition, but this condition is not the only condition that results in a reduction of RSL. However, if conditions occur where the antenna alignment may be suspected, the mechanics must be inspected and the antennas realigned. Faulty Antenna (connectorized antenna rc-models only) A faulty antenna is rare, but is still a possibility. In some cases, the mechanics of the antenna feed can get moisture inside, or a bad or weak connection in the pin and connector structure of the antenna may occur. A VSWR measurement of the antenna connection can be made to verify this condition. Improper Grounding In addition to being a potential human safety issue, improper system grounding is a somewhat common condition that can cause continuous bit errors or bit errors when metal objects come in 84 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios contact with the radio, transmission system, or racking system. If touching the radio causes errors, grounding is the cause. It can be difficult to identify grounding problems, but a professional electrician can normally inspect a system and identify if there are deficiencies in the grounding system. Insufficient Link Margin Ideally, the link was designed with enough link margin (fade margin) to allow for multipath propagation and atmospheric fading and still remain reliable. In some cases, link margin is compromised by economic factors, such as using low-cost RF cabling or lower-cost antennas that have less gain or deficient performance compared to higher cost transmission system components. In some cases, there may be antenna size restrictions that forced the design to not have the desired amount of link margin. If the link was designed with poor link margin, there are likely many cases of bit errors and outages. The antenna system and transmission line can be upgraded to help reduce this. If the link design was installed with sufficient margin, but RSL is reduced, the remaining link margin may no longer be enough to maintain a reliable link. The causes of RSL reduction were previously described, but are usually due to new path obstruction(s) or antenna misalignment due to wind or mechanical factors. The antenna height or location can be changed to overcome new obstructions. Realignment of the antenna, and/or improvement to mechanical structures can help overcome antenna misalignment. Moisture in the Transmission System If the connectors on cables and antennas and egress junctions are not properly weatherproofed, moisture can get into the transmission system and cause significant error conditions and erratic performance. In many cases, the transmission system must be replaced. A VSWR meter is one means to identify such issues. Conduct physical inspections often. If changes to the weatherproofing (such as cracking) are noticed, replace the weatherproofing before leakage occurs. 000000-001 2011-08-26 85 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios Back-to-back Bench Testing Use back-to-back bench testing to test the radio before installation, pre-configure the radio and connected equipment before installation, or in the troubleshooting process to identify if the radio hardware is the source of a system issue. It is a critical process, and often required or highly desirable for any installation or troubleshooting exercise. This section describes how to properly configure the radio hardware and accessories for a proper back-to-back bench test. For radio testing, there are two types of back-to-back configurations: Basic test (test general operation) Specification performance verification Basic Test The basic test is a simple test of radio functionality. It verifies that the radios are properly configured to communicate to one another, and verifies general radio performance as operational. For the basic test, the following items are needed: • Radio pair • Powering source • RF interconnect cable(s) (any length – short is best) • Fixed or variable attenuation, between 60 and 90dB (note: attenuation for basic test does not to be calibrated or precise) • Computer/terminal with either serial or Ethernet port (helpful, but not necessary) – If no computer is available, use the temporary hardware configuration key or DIP switch, depending on radio model (see Initial Configuration and Back-to-Back Bench Test) Connect the items as follows: Connect attenuation and (known-good) RF cable(s) between radio pair, shown in Figure 53. Configure one radio as Radio A; the other as Radio B Power on radio pair Figure 53 Basic back-to-back bench test configuration After connecting and powering on, observe the front panel LEDs to verify that the LINK and STATUS LEDs are green. If so, the radios are communicating and all radio-related alarm conditions are normal. 86 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios It can be beneficial to have a computer to verify configuration in case of red LEDs or to pre-configure the radio as desired for operation. Follow the instructions in Configuration and Management. Specification Performance Verification The specification performance verification is a more detailed test that allows you to verify that the radio’s output power and threshold specifications are being met. This is typically a test that would only be performed in a troubleshooting scenario, but can be performed before installation to provide a detailed record or ensure radio performance before installation. This test is identical to the basic test, but in place of the fixed attenuation, it requires the use of calibrated variable attenuation, or a set of calibrated fixed attenuators, or a combination of both, adding to a total attenuation value of 120dB, as measured at the operating frequency of the radio. In addition, a volt meter or computer is also required. Connect the system as shown in Figure 53, using the combination of fixed and variable attenuation between the radio’s RF ports. Connect the volt meter to either radio’s RSL test point and associated reference ground connection. In this test, it is desirable to use pre-tested RF cables, known to be good, and the insertion loss is known at the operating frequency. If the cables are short (6'/2m or less), you can estimate the loss, including connectors, to be less than 1dB each. The estimate of cable loss is critical to the overall confidence of the measurements made in this test. There are two critical specifications that can be tested in this configuration: • RF output power • Radio receiver threshold To measure transmitter output power, simply insert any value of attenuation between the radios between 60 and 90dB. Ensure that both RF output power settings are at maximum. Use the volt meter to measure RSL in both directions. The RSL measured value should match the appropriate value according to the inserted attenuation, such as: RSL = RF Output Power – cabling losses – total attenuation Verify output power by adjusting output power using the Exalt GUI (in administration mode) and evaluate the corresponding change to the RSL measurement. For threshold testing, the key is to insert a measured amount of loss that is close to, but not exceeding the radio’s specified system gain. System gain is the difference between RF output power and receiver threshold. At your selected modulation and bandwidth settings, determine the specified threshold performance, and choose a value of attenuation (including cable losses) that adds to roughly 5 to 15dB less than the system gain. For example, if the threshold for your measurement is -85dBm, the output power is +27dBm, so the system gain is 112dB. Choose a value of total attenuation in the range of roughly 100–105dB. Once this attenuation is inserted, verify RSL readings as in the first step, and then, using the GUI, reduce radio output power in 1dB steps until the receiving radio (the one whose output power not being adjusted) Link LED turns from green to yellow. This indicates that threshold has been reached. At this point, verify the equation for system gain using the new output power level setting and verify that the threshold performance is meeting or exceeding the published specification. Note: Due to the variation of measurements and accuracies involved in this test, you may read a measurement that is 1dB to as much as 2dB off of the expected value. It should be of no concern unless the value is more than 3dB worse than expected. 000000-001 2011-08-26 87 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios General Compliance and Safety The usage of radio transmission devices is subject to specific regulatory requirements governed by regional legislation.

As a result, Exalt’s WEEE compliance approach is to require the distributors and/or resellers in the EU to comply with each country’s national legislation by registration of the distributor or reseller as the producer and for the reseller/distributor to carry out and fulfill the legislative requirements of each national compliance scheme. Below is the crossed out wheelie bin symbol as required by the WEEE Directive. 94 000000-001 2011-08-26 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios EU RoHS RoHS is the acronym used to refer to the European Union (EU) Directive 2002/95/EC on the Restriction of the use of certain hazardous substances in electrical and electronic equipment. Hazardous materials are those chemicals and substances that are legislatively, market, or customer banned or restricted for use in products and/or manufacturing. There are six (6) RoHS substances: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr+6), polybrominated biphenyls (PBB) and polybrominated diphenylethers (PBDE). Other countries may be introducing legislation that results in similar restrictions of hazardous substances. Many Exalt products will continue to use lead-based solder under the exemption allowed for network infrastructure equipment. Small amounts of lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE can also be found in a few electrical and electrical components. 000000-001 2011-08-26 95 Exalt Installation and Management Guide ExtendAir® (TDD) Series Direct Mount Digital Microwave Radios Exalt Limited Hardware Warranty THIS IS AN AGREEMENT BETWEEN YOU AND EXALT COMMUNICATIONS, INC.
