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 were already performed. The EX-6i models utilize radio frequencies in the range of 5925 to 6425 and 6525 to 6875MHz. The EX-11i models utilize radio frequencies in the range of 10700 to 11700 MHz. In most countries these frequency bands are considered as licensed. This means that some form of frequency coordination and/ or licensing/registration is necessary for the legal use of the product. There may be limitations on classifications/types/sizes of antennas, effective isotropic radiated power (EIRP), specific frequency 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios pairs, antenna polarization, and other aspects of the link. Note: The link design engineer and/or professional installer must determine the legal requirements and limitations and engineer/install the system within the confines of all local regulations. Also, it is required that 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 be examined and complied with. In almost all cases, 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. In most cases, there are regulations, or device-based conditions that limit the use of the device, such as minimum or maximum gain antenna, antenna polarization, 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 some cases, a need for link registration, coordination, and fees that may apply to the system usage. Please consult your local regulatory organization(s) to determine usage requirements. Basic Features The EX-i Series FDD Digital Microwave Radios are single integrated units intended for all-indoor or enclosure-based mounting. The associated antenna is typically mounted on a tower or rooftop mast structure with RF cabling running from the antenna location, with an egress through the structure or enclosure, with proper lightning suppression and grounding, to the RF connector of the radio. In turn, the communications interfaces and power connections are directly applied to the radio, or in some cases, also with an egress through the structure or radio enclosure with proper lightning or surgesuppression devices and associated grounding. Figure 2 Indoor mount interconnection 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Figure 3 Enclosure mount interconnection For highest performance and reliability, it is advised to minimize the length of RF transmission line and other associated transmission system losses between the antenna and the radio's antenna port. Depending on model, combinations of the following data communication interfaces are provided: • 10/100/1000Base Ethernet (Copper or Fiber) • T1/E1/DS3/OC3 interfaces for synchronous voice traffic (number of TDM interfaces is determined by specific model and license-key configuration) The i-Series radios feature a wide-mouth direct DC connection (24V or 48V). All models 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 • Software-controlled channel bandwidth • Software-controlled center frequency tuning for easier frequency coordination 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 The reader is referred to the Exalt document, Guidance for Engineering and Site Planning of Terrestrial Wireless Links and the ExaltCalc path calculator. This document and calculator aid 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 modulation and occupied bandwidth • Anticipated throughput performance (TDM circuit support and Ethernet) 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 tolerance) • Regulatory limitations on transmitter output power setting and antenna type/gain • Noise/interference profile for the intended location (where applicable) Familiarization with the EX-i Series FDD Radios The EX-i Series FDD radios utilize frequency division duplex (FDD) radio transmission. This means that the signal transmits on one center frequency in one direction frequency, and in the opposite direction on a different center frequency. These frequencies are typically in predefined pairs, and are designated as ‘Low’ or ‘Lo’ for the radio transmitting on the lowest frequency, and ‘High’ or ‘Hi’ for the radio transmitting on the highest frequency. The two radio terminals are identical hardware, except for the configuration of externally-mounted diplexer filters on the rear panel. Both ends of a link use the same type of diplexer filter, but the diplexer filter is inverted with respect to how it is physically installed on the radio. Once the diplexers are connected on the radio terminals, the radio must be configured (through the browser-based GUI or 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios through Telnet/CLI) to match the installed diplexer configuration. Additional information on this configuration can be found in Rear Panel Diplexer Orientation and System Configuration Page. 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 The radios are shipped as single terminals.

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 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 – RF link connects in both directions – Traffic passes across the link Configure connected equipment and cabling – Test Ethernet (CAT5) cabling, and/or TDM 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, including installing any optional software license keys and configuring features controlled by license keys – Set transmitter output power to engineered or allowed level (see RF Output Power Setting) – Set operating center frequency – Set occupied channel bandwidth and Mode (modulation) setting 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 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 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios • 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 a value not greater than the legal maximum output power before connecting to the antenna and transmission system. Instructions for adjusting the output power can also be found in Power. Capacity Configuration The EX-i Series FDD 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: • Bandwidth • Mode (modulation) The setting of the above parameters determines the following performance factors: • Number of supported T1/E1/DS3/OC3 channels • Ethernet throughput Use a professional path-planning tool to determine optimum settings for the above parameters to meet the needs of your application. The following generalizations can be made with regards to these factors: • The higher the bandwidth, the higher the capacity • The higher the mode, the higher the capacity Note: Disable all TDM ports if there are no TDM interfaces connected. This shifts all available throughput to the Ethernet interface. Note: If a selected combination of the Bandwidth and Mode (modulation) parameters cannot support all the desired TDM ports, the ports that cannot be supported are automatically disabled. Priority is placed on the lowest port number. That is, the first port to be disabled, if necessary, is the highest port. See Cross Connect (X Connect) Page for more information. Radio Configuration Use the Exalt GUI to configure the radio terminals for diplexer filter configuration. 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 configured as shown in Table 1. 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Table 1 Factory default settings Parameter EX-i Series FDD Frequency Lowest frequency pair supported by software-configured diplexer Transmit Power Lowest setting for the defined terminal Bandwidth Lowest setting for the defined terminal Mode (modulation) Lowest setting for the defined terminal 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 Interfaces Enabled, Auto-negotiate 10/100/1000 NMS Access All Ethernet interfaces T1/E1/DS3/OC3 Settings 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). 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. 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 a specific port on the radio, such as management traffic to the ETH2 port. • 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. 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Note: For more information see, VLAN Configuration Page. 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 Command Line Interface (CLI). 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. Exalt radios also allow for “legacy” SNMP support for SNMPv1 and SNMPv2. Configuration of all passwords and community strings is performed from a separate Simple Network Management Protocol (SNMP) Configuration page. Note: MIB files can be downloaded directly from the radio using the File Transfer Page. 10 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios System Installation and Initiation Process The tasks required for radio installation and initiation are outlined in the following figure.

Keep a record for each end of the radio link and store a copy of these records at the radio location, at the opposite end radio location, and a central record storage location. • GPS coordinates for antenna locations at each site • Antenna heights above ground level (AGL), as mounted • Antenna model numbers, serial numbers, and specifications • Antenna polarization as mounted • Length/type of primary transmission lines at each site • Model number and serial number of RF lightning arrestors (for systems using coaxial transmission line only) • Length/type of secondary transmission line(s) • Transmitter output power setting as installed at each site • RSL as measured after antenna alignment at each site • Designed RSL per original design at each site • RSL reading with far-end power off (from each end) • Spectrum Analyzer plot with far end off at each site • Radio’s network management IP address at each site • Radio’s network management gateway address at each site • Radio’s operating frequency, bandwidth setting, and mode of operation • Optionally purchased extended warranty and/or emergency service contract details In addition, certain information may be desired for central record-keeping only: • Link security codes and log in passwords (stored in a secure place) • Photographs of complete installation • End-user sign-off/acceptance documentation (if any) • Photo of product identification label (part number, serial number, MAC address information) • Electronic copy of radio’s configuration file • Electronic copy of radio’s installed software 12 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Installation This section presents all tasks required to install the Exalt Digital Microwave Radio. Mechanical Configuration and Mounting TheEX-i Series FDD radios are one-piece designs intended for deployment in a telecom equipment rack indoors or in an appropriate environmental enclosure. The device must be deployed within an ambient temperature range as specified, and properly ventilated with no obstructions to the air intake and exhaust. The terminal occupies 2 rack units (2RUs = 3.5"/9cm) height in a typical telecom rack. In most cases, additional racked equipment can be placed directly above and/or below the device with no empty spaces in the rack. However, depending on power consumption and ventilation for adjoining devices, they may pass heat to the device, not allowing the radio to cool properly and increasing the risk of malfunction. Heat dissipation from the radio may also affect adjoining devices. Provide air space above and below the device, where possible. If not possible, a thermal analysis may be required by a professional engineer to determine the impact of thermal transfer between all adjoining units. Provide proper clearance for all cables and connectors attached to the device. All RF connectors, cables, and adapters must be rated for operation within the radio’s frequency range. RF connector losses must be accounted for within the link engineering design and output power settings. Rack Mounting Rack mounting hardware for a standard 19" (48cm) rack is included in the accessory kit. Attach the rack mounting brackets to the sides of the unit with the provided screws. The radio can be mounted in one of four configurations: • Front flush mount (front panel even with the rack mounting surface) Figure 5 Front flush mount configuration • Front projection mount (front panel extended forward from the rack mounting surface) Figure 6 Front projection mount configuration 202675-005 2011-08-30 13 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios • Rear flush mount (rear panel even with the rack mounting surface) • Rear projection mount (rear panel extended forward from the rack mounting surface) Figure 7 Rear flush mount configuration Figure 8 Rear projection mount configuration Note: Screws for attaching the radio to the telecom rack are not provided; use the appropriate screw type that matches the equipment rack. Table or Rack Shelf Mounting the System Affix rubber feet or adhesive-backed non-slip pads (not included) near the corners of the unit along the bottom panel when mounting on a table or a rack shelf. These pads help keep the radio stable on a wooden or metal surface. In many areas, it is necessary to strap the equipment to a table or rack shelf if mounting in this manner. In case of earthquake or other shock or vibration, or an accidental pull of a cable, the unit should be secured from falling. It may also be necessary to secure the AC adapter, if it is used. Radio Ports and Indicators This section provides a brief overview of the connectors, controls, and indicators on the device. Details about each item are in other sections of this document.

Ground loops to connected equipment must be avoided. Set the DIP switches accordingly. LED Indicators Table 3 provides details of the LED indicators on theEX-i Series FDD radios. See Alarms Page for information on how the Exalt GUI displays LED status.

This button allows easy and quick evaluation of the status of the remote-end radio. When the RMT LED is amber flashes, this is an alert that the remote end has an alarm condition. Press the RMT button to determine the alarm conditions. When the RMT button is pressed and held and local LEDs flash, this indicates that no remote-end information is available. This indicates that the remote radio is either not powered, is booting, or is not 202675-005 2011-08-30 17 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios linked in the direction towards the local radio, or the local radio is receiving excessive errors in this direction. It could also indicate a serious failure of either radio. Local-end LEDs (when this button is not pressed) in combination with remote-end information (from a technician located at the far end, and/or when the button is pressed) can substantially aid in rapid troubleshooting analysis. Rear Panel Diplexer Orientation The rear panel of the radio chassis arrives in a ‘blank’ condition, requiring the mounting and connecting of at least one diplexer filter. Figure 11 shows the rear panel without diplexers. Figure 11 Rear panel without diplexers One rear panel label indicates which diplexer type(s) are compatible with the chassis. Only mount and connect diplexers with matching type numbers. For typical radio configurations, one diplexer is mounted and connected on the rear panel. The diplexer selection and orientation is based on the precise center frequency and transmitter-to-receiver frequency spacing that is required for the link. This is typically determined during the licensing stage and subsequently during the purchasing process of the radio so that the diplexers match the frequencies and spacing required. Each diplexer can cover a range of center frequencies for transmit (Tx) and receive (Rx), and the ports on the diplexers are labeled to indicate that range, as shown in Figure 12. The diplexer can be oriented in one of two ways, and the right-side-up horizontal text on the diplexer indicates the configuration, as oriented. The designations on the diplexer are labeled TX-H (Transmitter High) or TX-L (Transmitter Low) to indicate if the transmitter frequency range is higher or lower than the receive frequency range. Likewise, the receive frequency ranges are labeled as RX-H and RX-L. TYPE MUST MATCH TX AND RX FREQUENCY RANGES DISPLAY HERE Figure 12 Diplexer labeling 18 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios In most configurations, the diplexers used for two ends of a link are the same diplexer, but mounted in opposite physical orientation (rotated 180 degrees relative to one another), as shown in Figure 13. NOTE TX AND RX FREQUENCIES MATCH AT EITHER END Figure 13 Diplexer orientation for a typical 'link' of radios Note in Figure 13, that this is the same diplexer for both radios, but they are mounted upside down relative to one another. It is a logical arrangement because one radio is configured to transmit across the same range of frequency that the opposite radio is configured to receive and vice-versa. Notes: The radio must have the software configured to match the ID number (orientation) of the diplexer, as shown in the right-side-up text at the top center of the diplexer. See System Configuration Page for details. On the GUI page, there is a Diplexer ID selection. This must match what is printed right-side-up on the installed diplexer. Once properly configured, the radio can tune to center frequencies and bandwidths accommodated by this diplexer, as mounted. Two semi-rigid coaxial cables are provided with each diplexer. These must be connected to the TX and RX1 rear-panel ports of the radio, as shown in Figure 12 and Figure 13. The frequency range shown on the diplexer label indicate the EDGE frequency range of the diplexer, not the center tuning range. The center tuning range is determined by the Occupied Bandwidth setting of the radio, and is 1/2 of the Bandwidth value (in MHz) in from the edges of the diplexer. Non-Standard Frequency Pairs From time to time, a licensing authority may assign a radio to be used on frequency pairs not accommodated by Exalt standard diplexers. In these cases, there can be two separate filters and a 202675-005 2011-08-30 19 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios circulator to accomplish the filtering and connections normally provided by the diplexer. There also may be special mounting plates to accommodate these devices, but the concept for this arrangement is similar to the above — the Tx frequency range on one side must match the Rx frequency range on the opposite side and vice-versa. The filters must be connected to the TX and RX1 ports on the rear panel. For non-standard pairs, use the ‘Other’ selection for diplexer type. The tuned Tx and Rx frequencies must be manually entered in to the frequency selection section in the GUI. The edge frequency range of the filters are labeled on the filters. The center frequency must be tuned to accommodate the bandwidth setting within the edge frequency range in accordance to the licensing requirements. Antenna Connection The connection leading to the antenna is the ANT port on the diplexer, which is typically an SMA female connection near the center of the diplexer. The diplexer kit includes a proper high-quality flexible RF cable to accommodate connection to an N-type female connector, either from the primary RF cable (if coaxial) or the coaxial jumper that feeds to that waveguide or to a waveguide adapter (sold separately). Most transmission system implementations use a waveguide. The waveguide should be mounted so that the connection is near the ANT connector port. The end of the waveguide run will use the waveguide-to-coaxial adapter, accommodating the high-quality flexible jumper cable (included). All losses associated with the jumper(s), adapter(s), and waveguide should be planned in the link budget used for engineering the link. Space Diversity Another diplexer configuration of the radio is for space diversity applications. This is where two antennas are used, mounted at different heights, to improve performance relative to multipath fading, which occurs on longer paths, paths over flat terrain, and/or paths over water or in dynamic weather environments. Space diversity requires two identical diplexers mounted on each radio, and a software license key that allows enabling the space diversity function in the radio. A typical space diversity diplexer configuration for a single terminal is shown in Figure 14. Note that both diplexers are the same type and orientation. One is connected only to the RX2 port for the diversity receive path. Figure 14 Typical Space Diversity diplexer configuration The opposite end of this space diversity link uses the same two diplexers, but rotated — in Figure 14, ID 102 is the orientation for both diplexers. Connect the secondary receive antenna to the ANT port of the secondary diplexer in a similar manner to the primary transmission line connection. 20 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Power The radio requires a DC power source within specifications. DC can be provided from a DC battery source, central lab/rack supply to the power injector (sold separately), or from the optional AC power injector. Note: No AC adapter is provided with these radios. Exalt recommends using a DC power plant. Read this section completely before applying power. Terminating the RF Connector Caution! Before applying power, the device’s RF connector 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 50-Ohm coaxial termination device to the RF port of the radio. The termination must be rated to 1W (or more). Example(s) include: – Broadwave Technologies P/N 552-200-002, or similar • Connect the complete transmission system. That is, the RF cabling including the antenna. The cabled antenna provides a proper termination for the RF output. • Connect a fixed (or a series of fixed) 50-Ohm attenuator(s) to the RF connector, either directly or at the end of an RF transmission line. The attenuator must be at least 30dB as specified at the operating frequency and rated for a minimum of 2W input power. Examples include: – Broadwave Technologies P/N 352-103-xxx – Bird 2-A-MFN-xx – JFW Industries 50FP-xxx-H6-N DC Power The DC voltage input accepts either 24 volts or 48 volts, nominal. Ensure that the power source is specified for the proper amount of current delivery capacity. The DC power may be connected as a positive or negative voltage supply, and be referenced to ground or ‘floating’ (differential voltage). There are different system grounding considerations depending on the nature of the DC supply grounding, and consult a qualified electrician or telecoms professional on the proper wiring and grounding process. Only one power source is required, but two power connectors are provided for input power redundancy. To connect a DC source, with the power disabled on the DC supply, connect proper gauge wiring to the DC supply. For most (short) power cable runs, 18AWG or 24AWG wire can be typically used. Strip the ends just long enough for enclosure to the DC radio connector (approximately 0.25 inches/ 6mm). If using stranded wire, the stripped ends inserted into the DC terminal connector must be solder-tipped. If using solid wire, a solder tip is not necessary. Ensure that the power wiring is long enough to neatly traverse, when properly dressed, between the source supply and the radio mounting location. If DC wires are to be exposed to outdoor environments, use wire in the proper weatherproof wiring jacket. 202675-005 2011-08-30 21 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios For longer runs of DC wiring, use a higher gauge wire and/or higher current source supply to overcome the additional resistance of the DC wiring. However, the DC connector for the radio may not be able to accept a high diameter wire, transition to thinner gauge near the end of the wiring run or use the maximum diameter wire for the entire wiring run, as long as it meets the powering requirements considering total resistance of the wiring and the power source current load capacity. Insert the wiring ends into the DC mating connector (supplied) and tighten the terminal screws to secure the wire into the connector. Do not connect the mating connector to the radio system and disable the power system. Pay close attention to the polarization of the DC signals coming from the DC supply and the ground conductor (if any), and ensure that they are connected to the proper pins of the DC mating connector. The connector mate on the radio is clearly marked on the front panel for proper polarization and for ground connection. Wire across the plus (+) and minus (–) terminals from the DC supply. In addition, place a separate jumper between the proper terminal and the ground terminal to reference one side of the power supply line to the radio chassis ground. In some cases, the DC system may need to be floating and this ground jumper is not necessary; however, many configurations require one side to be grounded for proper electrical safety. Warning! Consult a qualified electrician if uncertain about how to properly ground the system and connect power. When disconnecting power, always disconnect all sources of power supply. Figure 15 DC connectors Once the wires are connected to the mating connector, do not connect to the radio. First test the DC connection to the connector from the DC supply. Engage power on the DC supply, and use a volt meter to verify proper voltage level and polarity. Verify that the RF connector is properly terminated, as described in Terminating the RF Connector. Disengage power once again on the DC source, and connect the mating connector to the radio device. Engage power on the DC source. Verify radio is active by observing LED activity. All LEDs flash during the initial power cycle to verify that they are operational. Secure the DC connector using the integral captive screws at each end. This prevents accidental disconnection. 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 File Activation Page. The following parameters are configured after a reset to critical factory settings: • 22 IP Address = 10.0.0.1 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios • IP Mask = 255.0.0.0 • IP Gateway = 0.0.0.0 • Administration password = password (or ‘admin’) • User password = password (or ‘user’) • VLAN disabled To perform a reset to critical factory settings: Remove power. Hold the RMT button on the front panel while applying power. Continue to hold the RMT button through the entire boot cycle (approximately 45 seconds). The front-panel LEDs toggle during the boot cycle. Release the RMT button when LED behavior stabilizes. 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. Initial Antenna Mounting The antenna must be an exact model recommended by the path and site planning engineer(s). Mount the antenna at the proper height, mast/mounting location and polarization orientation as determined by the path and site planning engineer(s). The model type, location, and orientation of the antenna is critical with respect to achieving proper path clearance, as well as to mitigate external or selfinterference from nearby or collocated systems operating in or near the same frequency band. The antenna structure must be secure and safe with respect to the mounting of the antenna, transmission system weight, radio housing, and the combined weight of any personnel that may climb or attach to the structure. The combined weight of items and forces on the structure must be carefully considered in the design and construction of the structure. This must include the weight bearing on the structure in the highest wind conditions possible in the region, and with respect to all objects affixed to the structure. If additional objects are affixed to the structure in the future, it may be important to evaluate both the mechanical impact of these planned additions (with respect to wind and weight loading), as well as the potential impact to RF interference and frequency coordination (if additional radio equipment is anticipated). This is especially important if future equipment is likely to operate within the same frequency band. Once the antenna is mounted, cabled, and aligned, your goal is to never require modification. This prior planning is important in the path and site planning stages and in construction of the antenna structure. Follow the antenna manufacturer’s instructions for mechanical mounting of the antenna. Ensure that there is enough room around the antenna for alignment activities (moving the antenna in vertical and horizontal arcs), and for the RF transmission line to connect to the antenna connector unobstructed and within the specified bend radius requirements of the transmission line. 202675-005 2011-08-30 23 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios At this point, the antenna mounts should be fully secure to the structure, the feed of the antenna securely mounted to the antenna (if the feed is a separate assembly), and the azimuth and elevation adjustments not completely tightened in preparation of the antenna alignment activity. It is a good practice to connect the transmission line to the antenna connector as early in the process as possible, to reduce the opportunity for debris or moisture to enter either the antenna connector or the transmission line connector. Use a connector cover or other temporary measures to ensure that the connector is kept clear. Take extra care if the antenna is installed during inclement weather to ensure that no moisture gets inside the antenna connector at any time. Now the antenna can be aimed in the general direction required for the link. Use a compass, a reference bearing, binoculars or any other similar device to point the antenna in the direction (generally) of the far end radio, and then slightly tighten the azimuth and elevation adjustments so that the antenna maintains its general position and is safe to be left without additional securing. Refer to the Exalt white paper, Antenna Alignment, for more information on antenna alignment techniques. Transmission Line from Antenna to Egress Most installations for 6GHz and higher frequencies use waveguide line for the primary connection between the antenna and the radio device. Alternatively, and especially for shorter paths or where only short runs of transmission line are needed, coaxial transmission line can be used. Coaxial transmission line can either have a solid or braided shield. Solid-shield cables are more resistant to external signal coupling and interference, but are generally stiffer than braided cables. Consult the path or site engineer(s) to ensure that the proper materials are chosen for the installation and that all factors were considered. Refer to the Exalt white paper, Transmission Line for Exalt Indoor Radio Systems. Waveguide is the preferred transmission line approach for these radios, as it exhibits minimum loss to the antenna system. In some cases, coaxial transmission lines can be used. For coaxial transmission line, the larger the diameter of the transmission line, the lower the loss. So for longer runs of transmission line, larger diameter cables are highly advised. However, at every frequency, there is a maximum diameter cable that supports the operating frequency. Verify the specifications. This should is determined in the path and site planning process. It is critical that the transmission line and antenna be capable of supporting the same type of connector, or easily adapted. It can be important to minimize the number of connectors and adapters, and it is ideal that they match directly without adaptation. In most cases, 6GHz waveguide transmission line allows for CPR-137 flange connectors and antennas have the same connectors. Caution! Always follow the manufacturer’s termination process EXACTLY, and only use the manufacturer’s authorized tools and connectors for a given transmission line type. The manufacturers of transmission line typically offer instruction and certification for transmission line termination, and may also provide videos illustrating the process. There is no amount of extra care, education, precision, and effort that can be overstated for this process. Once the transmission line is connected to the antenna, traverse the exact route provided by the site planner. There is often a need for a small section of flexible transmission line near the antenna to accommodate the need for extra slack as the antenna is loosened and moved for the alignment process. Consult your transmission line manufacturer for the proper transportation, hoisting, securing, and grounding process. Always be very mindful of the entire length of transmission line to ensure that the transmission line is never twisted, kinked, or over-bent beyond the specified bend radius. Once a transmission line is over-bent or kinked, it will likely never recover its specified characteristics, even after straightening, and will often be completely unusable. 24 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios The opposite end of this primary transmission line typically terminates at the building or enclosure egress point. If coaxial transmission line is used, this is where to locate the RF lightning arrestor. Ensure that a proper termination to the connector-type of the lightning arrestor is made at this location. A drip loop may be required and proper securing hardware and grounding must be accommodated. If waveguide is used at the entry point, there is no need for lightning suppression. But install proper grounding according to the manufacturer's instructions. As soon as practical, weatherproof the connected ends of the transmission line to the antenna and lightning arrestor. This process should be delayed as long as possible to ensure that all systems are working properly before applying the weatherproofing. Once weatherproofing is applied, it may have to be removed for testing or installation modification. With this in mind, if the installation is occurring during inclement weather, take extra care at all times to ensure that no moisture enters any connector at any time. If moisture is suspected to have compromised the antenna or transmission line, it may render those devices useless without any means for remedy except for full replacement. Indoor Mounting On rare occasions the antenna can be mounted indoors behind a window. In these cases, there would not be a need for drip loops or an RF lightning arrestor. Use a very short transmission line connected directly between the antenna and the radio mounted nearby. The weatherproofing process can also be omitted. RF Lightning Arrestor RF lightning arrestors are needed for any coaxial connection that traverses from outdoors to indoors. They provide a direct path to ground for lightning strikes that may couple to or directly hit the outdoor transmission system or antenna structure. The RF lightning arrestor prevents any associated voltage and current from entering the building or enclosure, where it might harm the radio equipment, other equipment, or humans. The following lightning arrestor is an appropriate choice for this application: • Polyphaser WSXM Mount and ground the RF lightning arrestor in accordance to the manufacturer’s recommendations. Place it as close as possible to the egress point where the next piece of transmission line enters the building or enclosure. Minimize the distance to the egress to lessen the opportunity for lightning to couple to or strike the unprotected section of transmission line (if any). Where possible, use a bulkhead connector to eliminate any opportunity of this risk. Keep cable lengths behind the arrestor and into the egress substantially short (less than 3'/1m) as a safe practice. Consult a qualified electrician or installer in all cases of grounding and lightning arrestor implementation. Transmission Line from Egress to Radio A single transmission line section from the egress to the radio RF connection is always desired. Minimize the number of connectors and adapters. For indoor runs, a cable ladder or tray may be needed to properly secure the transmission line. In some cases, a short flexible jumper allows ease of connection to the radio’s RF connector. An installation with space around the radio to accommodate a gentle bend radius of the transmission line is also good for a direct connection. In all cases, ensure that the transmission line is not a pulling force of the RF connector on the radio. Transmission lines can be very stiff and can damage the connector if not dressed properly. Also, follow the transmission line manufacturer’s instructions for the proper use of cable securing devices. For waveguide installations, the waveguide typically runs horizontally from the egress across a cable ladder or tray, and then vertically down to the radio rack location. The waveguide should end as close 202675-005 2011-08-30 25 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios as possible to the rear panel of the radio. Included in the diplexer kits to accommodate the final connection to the radio are 6" (152.4mm) and 1' (304.8mm) RF cables and waveguide adapters. 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. 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. There are two primary facilities when using the radio to align the antenna: • RSL voltage test point using a volt meter (recommended) 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. • GUI RSL reading indicates the current RSL in dBm. Alignment of the antennas using the RSL test point can be accomplished in the following ways: • Radio near or at antenna location – Temporarily connect the radio to the antenna using a short piece of transmission line, so that the radio is very close to the antenna location – Run wires, as necessary, from the RSL test point to the volt meter so that the antenna installer can directly view the volt meter Note: Using this method, the final RSL voltage readings during alignment may be different (better) than the planned RSL, due to the short RF transmission line. Use the path calculation tool to determine the RSL that should result in this temporary configuration to ensure proper ideal alignment. • Run separate wires from radio mounted location to antenna location – Temporarily connect a set of wires from the RSL test point to the antenna location, to allow the radio installer to use a local volt meter Note: Due to the resistance of the cable, the RSL readings might be impacted. Use the thickest wiring possible. Test the impact of the voltage reading due to the wiring by comparing a direct measurement at the RSL test point as opposed to the end of the wiring. • 26 RF/DC coupler (for coaxial transmission line interconnection applications only) 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Install a temporary DC coupling device at the radio antenna port and at the antenna connector. Connect the RSL test point to the radio antenna port coupler, and the volt meter to the antenna connector coupler. • Verbal relay/walkie-talkie/mobile radio/cell phone – A person located at the radio front panel can use a short-range communication device or verbal relay to communicate to the antenna installer and read off RSL voltage measurements 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. 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. 202675-005 2011-08-30 27 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Configuration and Management This section describes the command line interface (CLI) and Exalt graphical user interface (GUI). Command Line Interface (CLI) Exalt Digital Microwave Radios provide a CLI to set key parameters on the system. Use the Console port for serial devices, or use the Ethernet MAIN or AUX ports for a Telnet session over a network connection. Bits per second: Data bits: Parity: Stop bits: Flow Control: 9600 None None 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 (for the Tx Lo radio, or after default reset). 10.0.0.2 is the IP address for a new (from factory) Tx Hi radio. Note: The accessing computer must be on the same IP subnet as the radio. If the radio supports DHCP and DHCP is enabled (see Ethernet Interface Configuration Page), which is the default setting for a radio shipped from Exalt (for the models with this feature), and your computer’s Ethernet port is set for DHCP addressing, the radio will configure your computer to 10.0.0.3 or 10.0.0.4, and no manual IP configuration is required. 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 menu choices available after log in. 28 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Figure 16 CLI root menu 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 Tx Lo and Tx Hi with default IP addresses of 10.0.0.1 and 10.0.0.2, respectively. If the radios are not new, the IP addresses and Hi/Lo and diplexer configurations may need to be changed. The initial priority is to connect to the radio’s management system to completely configure the radio. Assign the radios 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 Reset to Critical Factory Settings). Connect to the GUI using the default IP address (10.0.0.1 or 10.0.0.2), 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 supports DHCP and DHCP is enabled (see Ethernet Interface Configuration Page), which is the default setting for a radio shipped from Exalt (for the models with this feature), and your computer’s Ethernet port is set for DHCP addressing, the radio will configure your computer to 10.0.0.3 or 10.0.0.4, and no manual IP configuration is required. 202675-005 2011-08-30 29 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. Terminate the RF connector with a 50-Ohm termination or a fixed attenuator of at least 20dB (see Power). CAUTION! Do not connect the radios in a back-to-back configuration unless the IP addresses of the two radios are verified as different from each other. Note: The IP address subnet of the accessing computer must match the radio’s IP address subnet to connect using Ethernet. 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: • 30 Administrator (admin) – assigned complete permissions to view, edit, and configure 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios • 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 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. Verify diplexer configuration: – On rear panel, ensure that one end of the link is configured for Tx Low and the other end Tx High, and matching opposite channels from one another. 202675-005 2011-08-30 31 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios – In the GUI (System Configuration Page), the diplexer selection must match the type and orientation of the diplexer installed. 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), the channel plans match, but are opposite Tx and Rx frequencies for a link. 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 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 21, 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. The color of the panel indicates alarm status: 32 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios • 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. 202675-005 2011-08-30 33 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 34 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. – Note that the security key must be exactly 12 characters. Any alphanumeric character can be used. The link security key is case sensitive. 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. 202675-005 2011-08-30 35 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios • 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. • 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 bitlength 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 hexadecimal 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. 36 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios NTP and Time Zone Configurations Note: This feature is not available on all models. When Network Time Protocol (NTP) is enabled, the time and date is provided by the server. For NTP, set the IP address of the server where the time is to be retrieved. Up to four server IP addresses can be used. Any time zone can be selected, including Universal time. These servers must be available on the network that the radio is connected to. When NTP is disabled, the time and date is set on the Administration Settings page. Figure 24 NTP and Time Zone Configurations page 202675-005 2011-08-30 37 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Simple Network Management Protocol (SNMP) Configuration This page allows the enabling and disabling of the Simple Network Management Protocol (SNMP) functions. 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. See SNMP Traps. Figure 25 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. EX-i Series FDD 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. Note: Users are encouraged to avoid enabling SNMPv1/V2c support due to known security loopholes in these protocols. 38 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 (Figure 26). Not all EX-i Series FDD radios support SNMP traps. Consult the release notes for more information and enable the desired trap version by clicking the box to the left of the version of trap(s). Ethernet port(s) that are assigned to Management (per the setting on the Ethernet Interface Configuration Page) 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 26 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. 202675-005 2011-08-30 39 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios • Radio Reboot Trap: This trap is sent after any radio reboot to inform the manager of the reboot status. • Local Link Status Trap: This trap is sent when Link is in an 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). Independent traps can be set for the main and diversity links (when configured for space diversity). • Local Radio Status Trap: This trap is sent when Status is in an 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). • Remote Radio Status Trap: This trap is sent when Status for the remote radio is in an 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). • System/RX1/RX2 Local RSL Status Trap: These traps are 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. These traps are reset only if the RSL rises to 3dBm above the set threshold value and then drops below that value. Exalt recommends that these 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. Independent traps can be set for the System, RX1, and RX2 links. • 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. 40 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios File Transfer Page This page allows the administrator to upload and download files to and from the radio. Two types of files can be uploaded: configuration, and radio firmware. 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 27 File Transfer page Up to four types of files can be downloaded: radio firmware, configuration, MIB, and event log. 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) Configuration for more information. 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). Use the following steps to download a file. Select the type of file to download (configuration, radio firmware, MIB or event log). Click the Download button and wait for the radio to prepare the file for download. For some file downloads, a second page/link appears (Figure 28). Left-click the link on the page to download the file to a desired location. 202675-005 2011-08-30 41 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Figure 28 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, take as 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 • IP Address • IP Subnet Mask • Default Gateway 42 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 • Ethernet configurations 202675-005 2011-08-30 43 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 29 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. 44 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios System Configuration Page This page contains several critical system parameters. Figure 30 System Configuration page Most entries on this page are self-explanatory. The following lists unique or important parameters. • Set the Diplexer/Filter Configuration parameter by selecting the diplexer mounted on the rear panel that matches the label shown right-side-up on the diplexer. Select OTHER if using a custom diplexer assembly or a diplexer not in the list. If using OTHER, an independent Tx/Rx frequency input is required. On some models, when OTHER is selected an additional field is provided to program the insertion loss of the diplexer. This parameter can be found with the paperwork supplied with the original diplexer packaging. • Set the Radio Transmit Power (dBm) parameter to the desired level. The professional installer sets this value or dictates the value of this setting to the system administrator following the system 202675-005 2011-08-30 45 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. Set the Bandwidth (MHz) parameter to the value assigned to the radio license. 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 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 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. • Adaptive Coded Modulation (ACM) allows the radio link to adaptively adjust the modulation used to create the link, depending on multipath or fading conditions. The link must be licensed to allow this setting, specifying the legal maximum and minimum modulation settings. When enabled, select the Base (minimum) and Target (maximum) modulation settings. ACM must be configured on both sides of the link. The Base and Target settings must match on both ends. There are two pre-programmed ACM policies: 46 – Conservative switches down to the next modulation when the RSL is within 2dB of the current threshold, and switches up to the next modulation when at least a 5dB RSL margin exists above the next threshold. This slows and steadies the transition between modulations. – Aggressive switches down to the next modulation when the RSL is within 1dB of the current threshold (which is usually exhibiting some low-level BER), and switches up to the next modulation when at least 3dB RSL margin exists above the next threshold. This increases the transition between modulations, resulting in the highest capacity at all times. However, this can increase BER and cause erratic changes to throughput. 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Notes: • Changing Mode/Modulation will temporarily interrupt traffic. The Mode/Modulation setting must match at each end. Adjust the far-end radio first, and then the near-end radio. Changing Mode/Modulation 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-to-interference ratio, and in some cases, higher output power, therefore if changing to a higher mode (for example, from Mode 1 (QPSK) to Mode 2 (16QAM)), 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. • As modulation is reduced, the capacity of the system is also reduced. If the radio system is carrying TDM traffic (such as OC3, DS3, T1, E1), some interfaces that may be desired when the link is running at full-capacity (target modulation) may not be able to be supported. The Allocation Page allows configuration of TDM and Ethernet traffic as the radio changes modulation when ACM is enabled. • Changing the ACM settings can cause a temporary link outage. To minimize issues, change the far-end of the radio link first, and then adjust the near-end to match. • If Adaptive Modulation is disabled, both ends of the radio link require matching settings equivalent to the licensed modulation of the link. • Set the TX Frequency (GHz) and RX Frequency (GHz) parameters to the licensed center frequencies. The frequencies must match the same pair at both ends of the link, but in opposite Tx/ Rx orientation. • The Transmitter/Receiver (TR) frequency spacing is automatically determined based on the frequency settings. This is reported to verify the intended frequency settings, as a confirmation to proper input. Note: Changing RF Frequency will temporarily interrupt traffic. The RF Frequency parameter pair must be opposite at each end. Adjust the far-end radio first, and then the near-end radio. 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. • Set the Receiver Configuration parameter to RX1 Only for typical (1+0) links. – Enable RX1 Only/Enable RX2 Only (two receiver models only) allows manual selection of the receiver to isolate the receiver which is helpful for troubleshooting. – Enable Errorless Switching (primarily used for space diversity configurations) provides errorless switching between the two internal receivers or when deployed in a 1 + 1 MHS configuration, between the receivers of each terminal. This selection can also be used for receiver protection configurations to errorlessly switch between the two internal receivers if issues should arise. – Enable Linear Combining (primarily used for receiver protection configurations) provides additional system gain, however errorless switching may not occur during receiver switching events. This selection can also be used for space diversity configurations where the added system gain is more beneficial to the application than errorless switching. When linear 202675-005 2011-08-30 47 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios combining is enabled independent receiver performance data is not available on the Performance Page. – Enable XPIC/Vertical Enable XPIC/Horizontal implement these parameters in a cross-pole interference cancellation configuration. In this configuration, one terminal at one end of the link must have Enable XPIC/Vertical enabled, while the other terminal at that end must have Enable XPIC/Horizontal enabled. XPIC provides a means to connect two parallel links across a cross-polarized antenna to achieve higher capacity than one independent link. • RX RSL Differential parameter (for space diversity configurations) if transmission system specifications are different from one another for the two connected antennas (such as in a Space Diversity configuration with different size antennas for each receiver), enter the anticipated RSL delta in this field. The radio provides alarm conditions when RSL is not meeting anticipated levels. If this alarm is not desired, click the disable button. • RSL Monitor parameter controls which RSL is presented at the front-panel RSL voltage port. This can be selected to either RX1 or RX2 (for two-receiver models), or COMBINED for the highest value of either (for two-receiver models). It is recommended that you select the independent port of interest if using this port for antenna alignment. • Enable the Automatic Transmit Power Control (ATPC) parameter (if authorized) to increase transmitter power if the RSL drops below the programmed value. The maximum output power for ATPC is either 10dB or the maximum power capable from the radio (including installed license keys). Use the ATPC timers to ensure that the radio meets regulatory requirements. Timer information is provided in the ATPC Statistics Page under the Monitor section. Also, the diagnostics chart for RSL illustrates the ATPC threshold level to accomplish a proper diagnosis of the RSL relative to ATPC. • The External Alarm Inputs parameter can be ignored unless connecting external alarm sources to the radio to monitor the status of these external alarms through the radio management system (see Interface Connections). 48 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Allocation Page This page allows the administrator to determine how the TDM interfaces (T1, E1, DS3, OC3, etc.) and remaining Ethernet capacity are allocated when ACM is enabled. Since ACM changes the capacity of the radio, it is critical to determine how those changes impact the traffic carried over the link. Figure 31 Allocation page The left side of the chart shows the different modulations available for ACM. Columns display under different TDM type column headings (such as DS3 and T1 shown). Selection of how many of each interface is determined by the selections for each modulation. The bar graph color codes allocation of the TDM interfaces, showing each interface and the relative capacity it is occupying. Orange indicates remaining Ethernet capacity for that modulation. At the right of the graph, the full-duplex Ethernet capacity displays in Mbps. The total full-duplex capacity displays in the System column. It may be necessary to configure the TDM interfaces. A link displays under the graph to ease configuring any TDM interface. Note: The allocation of TDM interfaces only defines HOW MANY channels are allocated; it does not define WHICH physical ports are allocated. Priority of port assignments is controlled on the Cross Connect (X Connect) Page. If a TDM allocation change occurs between modulations, the priority defined in Cross-Connect determines which ports are added or dropped. 202675-005 2011-08-30 49 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Ethernet Interface Configuration Page This page allows the administrator to set the muting, alarm, and duplex settings of the ETH1, ETH2, and ETH3 connections, and allows determination of the management information for in-band (carried over the air and available from both Ethernet connectors on either end of the link) or out-of-band (not carried over the air and only available from the local PoE connector). Figure 32 Ethernet Interface Configuration page The management function of each port can be assigned as: • In-Band Management – All ports can pass traffic over the link and also have access to management of the radio. Management traffic is carried over the link. • Out-of-band Management – Each port can be set to either Traffic or Management. All ports set to traffic are connected together and pass traffic over the link, and all ports set to management are connected together, but separated from the traffic and do not go over the link. Management is not available over the wireless link in this configuration (unless externally switched or routed to a Traffic port). • Legacy Management (EX-6i-DS3-GigE only) – ports can be selected as Traffic, Management, or Traffic+Management. In this configuration, all ports set to Traffic are NOT connected together, but each individual port has the ability to send and receive traffic over the link. Too, all ports set to Management are NOT connected together, but each individual port can send and receive management information to the connected radio. 50 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Notes: • The Legacy Management setting is not recommended; it supports users running v1.1 firmware or lower so that upgrades do not cause network loops or other issues. If your configuration has a mixture of both independent and mixed function interfaces, change these settings to either In-Band or Out-of-band Management and make the appropriate external network accommodations to support this new setting. Contact Exalt support for details. • The radio requires that a minimum of one interface have access to management (either by setting to Mgmt or Traffic+Mgmt). • If VLAN is enabled, VLAN IDs assigned to separate interfaces must match the topology of the Function setting on this page. For example, any port with access to Management must include the Management VLAN ID when configuring VLANs. • Mode allows for specific negotiation settings on each interface. Exalt recommends setting these interfaces to Auto Negotiation. However, there may be cases where connected equipment performance can be improved by using a specific negotiation type. • Alarm determines if the radio goes into alarm when the interface connection is disconnected or not sensed. Enable alarms on in-use interfaces. Unused interfaces should have alarms disabled. • Mute when enabled mutes the interface on link outage. This accommodates connected equipment that requires loss of connection sense to enact network alarms. For example, Spanning Tree Protocol can be enabled on loss of connection. Note: The radio prohibits setting all interfaces to Mute, as this does not allow management access to the radio. Do not mute the port with access to management. 202675-005 2011-08-30 51 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios T1/E1 Configuration Pages These pages allow the administrator to selectively configure 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). Click the Set to T1 or Set to E1 button to toggle the page between T1 and E1. This will interrupt traffic. 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 Tx-Low radio for T1/E1 enabling supersedes the settings on the Tx-High configuration, and changes the settings on Tx-High. Note: Certain combinations of the Mode/Modulation 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 viable for configuration and is disabled. If only two circuits can be carried, both ports 3 and 4 are not available. Increasing the Mode/Modulation parameter and/or increasing the Bandwidth parameter results in an increase in the supported number of T1/E1 circuits This is because the T1/E1 traffic is given priority over Ethernet traffic. T1 Interface Configuration Page This page allows the administrator to enable/disable the alarm for 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 Loopback). Carefully consider alarm enabling relative to the number of ports allocated (see Allocation Page) and their relative priority (see Cross Connect (X Connect) Page). If alarms are enabled, a red alarm occurs when a port is allocated and no T1 signal is detected. A yellow alarm occurs s when a port is not allocated and a T1 signal is detected. Disable alarms for unallocated ports or ports with traffic connected but that are not in use. 52 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Figure 33 T1 Interface Configuration page E1, DS3, and OC3 Configuration Pages For all other TDM configurations (E1, DS3, and OC3), configuration is nearly identical to the T1 configuration. However, the LBO and AIS settings must match the interface standard. For some DS3 interface units, additional configuration is provided to select the ground configurations of the DS3 ports (grounded or not grounded). When setting Alarms, review the Allocation and X-Connect settings relative to how many and which specific ports will be active for different ACM states. See the T1 Interface Configuration Page section for advice on alarm settings. E1 Interface Configuration Page This page (Figure 34) 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). 202675-005 2011-08-30 53 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Figure 34 E1 Interface Configuration page DS3 and OC3 Interface Configuration Pages These page allow the administrator to configure the DS3/OC3 interface. These interfaces should be disabled if there is no DS3/OC3 connected. The associated throughput is then allocated to T1/E1 and/ or Ethernet. 54 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Figure 35 DS3 Interface Configuration page The Line Build Out (LBO) can be set for this interface. Also, the Automatic Insertion Signal (AIS) can be disabled, or set to an All-Ones (A1S) or All-Zeros (A0S) signal type. In addition, some loopback functions are provided as described in Loopback. Figure 36 shows the OC3 Configuration page. 202675-005 2011-08-30 55 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Figure 36 OC3 Configuration page Loopback Loopback is provided for any enabled TDM port. The choices are: • No Loopback (default) • External (local) • External (remote) 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 37 and Figure 38). 56 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Figure 37 External (remote) loopback Figure 38 External (local) loopback Note: For DS3 interfaces, the implementation is slightly different than shown in Figure 37 and Figure 38. The remote loopback will send traffic from the local In to the local Out as shown, but the far-end In-to-Out connection is not made. The local loopback will loop the local In-to-Out, but does not create the over-the-air loopback shown in the opposite direction. When a local TDM port is configured for External (remote) loopback, it is the same as configuring the remote radio for External (local) loopback. 202675-005 2011-08-30 57 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios MHS Configuration Page This page provides the capability to configure the system for Monitored Hot Standby (MHS). These configurations implement a second terminal at one or both ends of the link for hardware protection and/or path protection. MHS cannot be configured when Adaptive Coded Modulation (ACM) is enabled. Figure 39 MHS Configuration page For MHS, the two terminals at one end of the link are connected to the same antenna. One terminal is in a ‘standby’ configuration, and is automatically selected if issues are identified with the other terminal. Special MHS protection cabling (sold separately) is required to connect the PROT ports of the terminals, along with a standard straight-wired CAT5 cable for the EXP ports of the terminals. One terminal at the endpoint is designated as primary and the other secondary. For MHS configurations, generally the primary terminal is connected to the on the lower-loss side of the MHS receiver coupler. The Lock On features are provided for troubleshooting. The default setting is No Lock on (Normal), to enable protection. When swapping cables or hardware on one of the terminals or for troubleshooting, set the primary or secondary radio to Lock On and set the amount of time. MHS switching can be implemented in a ‘hybrid’ fashion instead of selecting one complete terminal. In this configuration the interface circuitry of one terminal may be in use, while the RF circuitry of the other terminal is in use. This hybrid implementation yields faster MHS switching and requires no user intervention. 58 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. Figure 40 VLAN Configuration page The top table allows the configuration of the default VLAN assigned to each interface and the VLAN used for radio management. VLAN may be enabled in one of three different ways: • Where programmed VLANs from the bottom table are passed and all other traffic is blocked. • Where programmed VLANs from the bottom table are passed, untagged traffic is passed, and VLANs not in the table are blocked. • Where programmed VLANs from the bottom table are passed, untagged traffic is tagged with the default VLAN assigned to the interface, and VLANs not in the table are blocked. 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. In the bottom table, create a list of VLANs to pass on the selected interface. This list can be in the form of individual VLAN IDs, separated by commas, and/or ranges of VLAN IDs. (for example, 105, 109. 111–145, 156, 254–275). 202675-005 2011-08-30 59 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios The “new value” list matches the “current value” list to allow easy editing by subtracting, adding, or otherwise modifying the list before clicking Update. Note: The VLAN IDs that are assigned to any interface should support the Function settings on each interface as defined on the Ethernet Interface 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), or • Connect to the Console port using a serial interface and the CLI, as described in Command Line Interface (CLI), and reconfigure the VLAN settings. 60 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Ethernet Rate Limiting Page 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 default setting is disabled. The rate is in Mbps or kbps, as specified. Use the Update button to save changes. Figure 41 Ethernet Rate Limiting page 202675-005 2011-08-30 61 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Ethernet Learning Page This page allows enabling or disabling Media Access Control (MAC) learning. This is a universal setting for all Ethernet interfaces. Figure 42 Ethernet Learning page Some network configurations may broadcast the same MAC Source address on multiple interfaces, and if learning is enabled, data transport errors can result. For these cases, disable learning to improve networking functionality. However, disabling learning can cause unnecessary traffic to occupy the interfaces and the radio link, and lead to lower throughput performance. 62 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Syslog Configuration Page Syslog serves as a remote means to receive event log messages (configuration and alarm state changes) for network management and/or record keeping. Figure 43 Syslog Configuration page To enable the syslog, check the Remote host logging option and input the IP address for the remote host. See Event Log Page for filter descriptions. 202675-005 2011-08-30 63 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Ethernet Aggregation This page allows enabling or disabling the Ethernet Aggregation function. When enabled, the radio can be interconnected with other radios (typically in parallel) to aggregate the Ethernet traffic so that only one connection is needed at each end without external routers or aggregating switches. Figure 44 Ethernet Aggregation page The radio that has Ethernet Aggregation enabled is the ‘primary’ radio in the aggregation arrangement, and the EXP port can be connected to another radio’s EXP or GbE port or connected to a simple GbE switch connected to other radio’s EXP ports and/or GbE ports. The net result of this feature is that a set of radios appear as ONE connection to the LAN/WAN. If a radio link fails or degrades for any reason, the capacity scales accordingly, up or down dynamically up to a maximum of 1Gbps full-duplex. For aggregation, all radios at one side of the link must be designated ‘East’ and at the other end, designate all as ‘West.’ Each radio has an Aggregator ID that corresponds to the ‘Radio Link’ information at the bottom of the table. For the primary radio, the relative throughput percentages are entered for each radio in the aggregation set. Radio Link 1 is the radio itself. For links running ACM, use a percentage based on target modulation throughput (maximum). For example, in a two-radio link aggregation scenario, if the primary radio carries 300Mbps full-duplex capacity at target modulation and the second radio carries 200Mbps, then the percentage applied to Radio Link 1 Throughput should be 60 and Radio Link 2 40. 64 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Cross Connect (X Connect) Page This page has two primary purposes. One is to determine the priority of TDM interfaces when ACM is enabled and allocation for the associated TDM interfaces is different from one modulation to another. The other is to allow a cross-connect function for port assignments from one end of the link to the other. Figure 45 Cross Connect (X Connect) page For the priority selection function, for example, if allocation has been set to carry 16xT1 interfaces under all conditions except for the lowest modulation setting, where only 4xT1 are allocated, the priority 1 through 4 ports would remain active in the lowest modulation setting. For the cross-connect function, the port numbers at both the near-end and far-end are mapped by the administrator to determine traffic flow through the radio - for example, allowing traffic on Port 1 of one radio to be virtually connected to Port 11 on the other. This can relieve the need to commission external cross-connect or channel banks, or relieve an issue with a bad port or bad connection or cable to a port by re-prioritizing and re-connecting it. 202675-005 2011-08-30 65 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 46 Alarms page Table 5 lists alarm status conditions that appear on this page. Table 5 Alarm status indicators Label Status Link System Indicates RF link status: RX Alarm 66 • Green Solid = Error-free connection (BER<10e-6) • Yellow Solid = Errored connection (10e-3>BER >10e-6) • Red Solid = No link (BER>10e-3) When Rx RSL Differential is enabled, provides alarms for Space Diversity configurations. • Green Solid = The Rx values of the two receivers are within 5dB of the programmed differential value. • Yellow Solid = The Rx values of the two receivers are further apart than 5dB of the programmed differential value. 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Table 5 Alarm status indicators (Continued) Label Status ATPC Indicates Automatic Transmit Power Control status: PA Protection Ethernet DS3 Input T1/E1 Input Temperature Internal Fan • Green Solid = ATPC is enabled, but not active. • Yellow Solid = ATPC is active. • Red Solid = ATPC timers have reached limit (and link has not recovered to target RSL). • Grey = ATPC is disabled.

There are 3 fans for redundancy. • Green = Fan OK • Red = Fan in alarm External Inputs (1 and 2) Indicates the status of the external alarm inputs from the ALARMS connector, in accordance with the open/closed logic defined on the System Configuration Page. Link Security • Green = Security keys match • Red = Security keys do not match • Grey = Link is down 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.

Figure 47 MHS Status page The ‘local’ radio is the terminal you are logged into, and the ‘partner’ information is the terminal that is configured as its MHS partner. One of these must be designated as Primary, while the other is designated as Secondary (see MHS Configuration Page). • The RF Status indicates which radio is being used for the RF circuitry of the link and which one is on standby. • The Interface Status indicates which radio is being used for the interface circuitry of the link and which one is on standby • The Protection Link Status refers to the communications between the PROT ports of the terminals. • The Configuration status indicates if there are any mis-matches in required configurations between the two terminals. The following items must match between partner radios: • – Hi/Lo orientation – one terminal must be primary and the other secondary – all TDM enabled channels and their respective alarm enabled states – Ethernet traffic/management, alarming and muting The Expansion Link status refers to the communications between the EXP ports on the terminals. 202675-005 2011-08-30 69 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 48 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 (one 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. • 70 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 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. • 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. • 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. • 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. • 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. • 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 record performance and reset the statistics so that the counters can more precisely pinpoint issues. 202675-005 2011-08-30 71 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. When ACM is enabled on the System Configuration Page, the Performance page lists ACM statistics (Figure 49). Figure 49 Performance page with ACM statistics The ACM Performance table provides a reference of the maximum and minimum modulation settings that are selected on the System Configuration Page and their associated throughput. The Active column illustrates the current radio configuration. 72 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios ATPC Statistics Page This page provides timer information for the Automatic Transmit Power Control (ATPC) function (Figure 50). Regulations require timers for ATPC and ATPC may not operate over the authorized time (up to 5 minutes at maximum allowed power without returning to target RSL). In addition to providing statistics, the timer can be reset. Figure 50 ATPC Statistics page 202675-005 2011-08-30 73 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 only the level(s) of desired information. The log contains the last 1000 events. Events are deleted on a FIFO basis. The event log can be cleared and downloaded from the file transfer page (some models may require a software upgrade to enable this feature). A screen capture of the browser window can serve as a useful record.

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 54 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, if 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-minute interval. 202675-005 2011-08-30 77 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 interference, atmospheric changes, transmission system issues (such as problems with cables, connectors, or antennas), or possibly radio hardware problems. 78 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 55 Ethernet Utilization page Note that 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 Ethernet Utilization 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 to activate this function. When the watermark level function is enabled, a line on the chart appears for data comparison to the watermark. 202675-005 2011-08-30 79 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios PA Control Page Radios configured with Power Amplifier (PA) protection switching automatically bypass the PA on detected PA failures. The PA Control page provides ability for extended troubleshooting related to the PA. Select from the following three options: • Force Normal places the PA protection in its normal state where if issues are detected, the PA is bypassed, dropping the transmit power approximately 10dB. In most link conditions, the link is maintained. • Force High forces a no PA bypass condition. If a PA issue is detected, this can help verify improper performance. • Force Low forces a PA bypass. This is useful for troubleshooting and initial link commissioning. For link testing, this option ensures that the link has sufficient margin to maintain connection if PA protection switching occurs. Figure 56 PA Control page 80 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Spectrum Analyzer 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 57 shows the Spectrum Analyzer page. Figure 57 Spectrum Analyzer page 202675-005 2011-08-30 81 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. 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 58), 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 58 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 82 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. 202675-005 2011-08-30 83 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Reboot Page Use this page to reboot the radio.

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 antenna or transmission system • 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 96 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD 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: • Frequency pair matches (oppositely) at each end of the link • Mode (Modulation) matches at each end of the link • Bandwidth matches at each end of the link • Ethernet interfaces are enabled, as desired • Ethernet interfaces are selected for Traffic, Management, or Traffic plus Management, 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 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 202675-005 2011-08-30 97 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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 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 sign of this issue. Another method to test for this condition is to decrease the output power of the radio system (at each end, one end at a time). 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. This is less common for licensed systems, but still can occur. 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. 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 98 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. 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). Local regulations may not permit antenna system changes without re-licensing or other notification. 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 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 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. 202675-005 2011-08-30 99 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios 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. 100 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD 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 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 66. Configure the frequencies of the radio to be the same pair, with opposite Tx and Rx orientation. Power on radio pair Figure 66 Basic back-to-back bench test configuration After connecting and powering on and connecting a PC for GUI radio management, verify that the LINK and STATUS are green. If so, the radios are communicating and all radio-related alarm conditions are normal. 202675-005 2011-08-30 101 Exalt Installation and Management Guide EX-i Series FDD 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 66, 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. 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. 102 202675-005 2011-08-30 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios Once threshold is verified in this direction, repeat the process in the opposite direction by adjusting RF output power of the radio at the opposite end. Return the first radio to its original power setting before adjusting the second radio. 202675-005 2011-08-30 103 Exalt Installation and Management Guide EX-i Series FDD Digital Microwave Radios General Compliance and Safety The usage of radio transmission devices is subject to specific regulatory requirements governed by regional legislation.
