Exalt i-Series Installation and Management Guide
Note: This manual uses terminology to distinguish the characteristics
of specific radio models. The term standard refers to the EX-2.4i, EX-4.9i
and EX-5i models. The term -16 refers to the EX-2.4i-16 and EX-5i-16
models. When no specific mention is made or the term i-Series is used,
this refers to all models.
Generally, the i-Series models require a clear line-of-sight and proper path clearance to
achieve a high-performance, reliable connection. Perform professional path engineering
and site planning BEFORE installing this equipment.
The primary focus of this document is the installation and maintenance of the digital
microwave radio, and assumes that path engineering and site planning has already been
performed. Please refer to the Exalt document, Guidance for Engineering and Site
Planning of Terrestrial Wireless Links, for detailed information on these activities.
The EX-2.4i models utilize radio frequencies in the range of 2400 to 2483.5MHz. The
EX-5i models utilize radio frequencies in the range of 5250 to 5850 MHz. In most
countries these frequency bands are considered as ‘license-exempt’ or ‘unlicensed.’ This
means that virtually any user may use these frequencies freely, without paying for access,
or any type of pre-notification, post-notification or registration. As a result of this
designation, users may also move or change these systems at any time, with significant
flexibility to the location, orientation and configuration of the system. However, due also
to this designation, there may be uncontrolled interference from other similar devices that
occupy this spectrum. In these cases, it is up to engineering and maintenance personnel to
design the system with existing and future interference sources in mind, recognizing that
there is a chance that the interference conditions could be very dynamic, and outages may
occur on the system as a result, and that, in some very rare cases, the system may cause
interference into another system and may be required to be disengaged or modified/reoriented to eliminate the interference.
If the spectrum in your country is designated as ‘license-exempt’ or similar, this does not
infer that the installer may configure the system in any manner at any location. In most
cases, there are regulations, or device-based conditions that limit the use of the device,
such as maximum gain antenna, antenna types and maximum output power, as well as, in
some cases, application limits, limited geography of use, and other unique regulations.
The link design engineer and/or professional installer must determine these
limitations and engineer/install the system within the confines of all local
regulations. Also, it is required to examine any regulations that may apply to peripheral
equipment, installation and cabling of the system that may be regulated for human safety,
electrical code, air-traffic control, and other safety-related categories.
In certain countries, the spectrum for this product is NOT considered to be licenseexempt. In these cases, there may be additional regulatory requirements concerning the
location, frequency, power, orientation, configuration, and other aspects of the system,
including, in some cases, a need for link registration, coordination, and fees that may
apply to the system usage. Please consult your local regulatory organization(s) to
determine usage requirements.

The EX-4.9i utilizes frequencies in the 4940-4990MHz range, and is typically a licensed
band reserved for use by Public Safety agencies and applications. This band is not
generally available outside of North America.
In almost all cases, either for license-exempt or other designation, the product itself must
be authorized for use in your country. Either Exalt or Exalt’s agent must have applied for
certification or authorization to allow the sale and deployment of the system within the
country. It is also possible that only certain versions or configurations of the device are
allowed within a particular country. Please contact Exalt or your authorized Exalt
representative for information pertaining to your country.
Note: It is the professional installer’s responsibility to ensure that
the radio system is implemented in a legal fashion. Exalt is not liable
for any unsafe or illegal installations.
Basic Features
The i-Series 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 surge-suppression
devices and associated grounding.

Pre-installation Tasks
This section describes the steps necessary to prepare a site for the installation of the Exalt
Digital Microwave Radio.
Link Engineering and Site Planning
Design all terrestrial wireless links prior to purchase and installation. Generally,
professional wireless engineering personnel are engaged to determine the viability and
requirements for a well-engineered link to meet the users’ needs for performance and
reliability.
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 TDD frame length and occupied bandwidth
•
Anticipated throughput performance (TDM circuit support and Ethernet)
•
Anticipated system latency
With respect to radio path and site planning, these radios are generally identical to any
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

•
Impact on throughput and latency relative to link distance, occupied bandwidth, and
TDD frame size setting, and the planned implementation of these parameters
Familiarization with i-Series Radios
The i-Series radios utilize time division duplex (TDD) radio transmission. This means
that the transmitted signal in both directions uses the same center frequency and transmits
in one direction for a period of time, and then in the opposite direction for another period
of time. This total period of time is referred to as the frame length or TDD frame length,
and is further discussed in Time Division Duplex (TDD) Factors on page 25.
The two radio terminals are identical hardware, except for the TDD setting in software.
When the radios are in their default state, both radios are configured as Radio B. One end
of the link must be configured as Radio A before the two ends of the radio system
can communicate.
It can be considered that Radio A is the primary radio in the link. Radio A provides the
master clock and control to Radio B. For most applications, it is not important how the
radio link is oriented, only that one end is configured for Radio A and the other for Radio
B. For some applications (such as, multi-radio hub sites or repeaters), the orientation of
the radio systems may be more critical. See Link Orientation and Synchronization on
page 26 for details.
There are three ways to configure the radios for Radio A/B determination:
1.
Use the Exalt browser-based graphical user interface (GUI) – preferred.
2.
Use the temporary hardware configuration key, in case of emergency (all models
except for -16 models).
3.
Use the front panel DIP switch, in case of emergency (-16 models only).
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 on page 52 for details on how
to connect to and use the browser-based GUI interface.
Standard models: The temporary hardware configuration key can be used when no
computer is available to complete Radio A/Radio B configuration and there is a need for
immediate bench testing or initial link installation and/or antenna alignment. See Radio
A/B Configuration on page 27 for details on the temporary hardware configuration key.
-16 models: The front panel DIP switch provides a fast temporary means for Radio
A/Radio B configuration. See DIP Switch Settings (-16 Models Only) on page 114 for
details.

Back-to-Back Bench Test and Configuration
Every Exalt digital microwave radio goes through extensive quality testing and
performance evaluation over the full operating temperature range prior to shipment.
However, before installation, it is strongly advised to perform several tests and tasks that
are much more difficult to perform once the radio link endpoints are distant from one
another. A back-to-back bench test and pre-configuration will provide confidence that the
radio link is operational and properly configured prior to installation, so that if
troubleshooting is necessary, the radio hardware and configuration settings are eliminated
from the troubleshooting process. Verify the following in the back-to-back testing:
•
Confirm that the radio system is generally operational
¶ Radios power-up with planned power and wiring solutions
¶ RF link connects in both directions
¶ Traffic passes across the link
•
Configure connected equipment and cabling
¶ Test Ethernet (CAT5) cabling, and/or T1/E1 cabling, any auxiliary connector
cabling and configure all interfaces
¶ Configure IP settings for configuration and management
¶ Configure passwords and security modes
¶ Become familiar with the configuration and management interfaces through the
Exalt GUI interface
•
Configure radio parameters
¶ Set transmitter output power to engineered or allowed level (see RF Output Power
Setting on page 25)
¶ Set operating center frequency
¶ Set link distance, occupied channel bandwidth, and frame length
•
Make detailed radio performance measurements
¶ Measure transmitter output power
¶ Measure receiver threshold performance
¶ Confirm unfaded error-free performance
Some of these tasks may not be possible or practical within a bench test environment due
to the nature of the remote connectivity of peripheral equipment. However, it is good
practice to perform as much as possible in this environment to minimize field/installation
time and troubleshooting efforts.
5000001

Exalt Communications, Inc.
Exalt i-Series Installation and Management Guide
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 backto-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 on page 104 for detailed
instructions.
RF Output Power Setting
The maximum RF output power is bounded by one of the following criteria:
•
Maximum RF output power setting capability of the radio device
•
Maximum RF output power allowed/authorized by the local government regulations
and for this specific device
•
Maximum effective isotropic radiated power (EIRP) of the transmission system
allowed/authorized by the local government regulations and for this specific device
•
Desired RSL to not exceed the maximum RSL allowed by the device
•
Desired RSL to minimize/eliminate interference into neighboring systems
Note: In many cases the radio must be pre-configured for legal
maximum output power before connecting to the antenna and transmission
system. Instructions for adjusting the output power can also be found in
System Configuration Page on page 64.
The following information on how to set the proper power for each country is based on
the pertains to specific regulatory requirements based on up-to-date information for
countries where these radios are authorized is in Appendix A. A list of recommended
antennas is listed in Antenna/Transmission System on page 45.
Time Division Duplex (TDD) Factors
The i-Series radios are very dynamic, allowing the installer to optimize and control the
performance of the radio system for the intended application. The following parameters
must be carefully determined during the link engineering phase:
•
Link distance
•
Bandwidth
•
TDD frame size
•
Mode (modulation)
The setting of the above parameters determines the following performance factors:
5000001
2007-06-25
25
Exalt Communications, Inc.
Exalt i-Series Installation and Management Guide
•
Number of supported T1/E1 channels
•
Ethernet throughput
•
System latency (delay)
Use the ExaltCalc calculator 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 shorter the TDD frame size, the lower the latency
•
The shorter the link distance, the lower the latency, the higher the throughput
•
The longer the TDD frame size, the higher the throughput
•
The higher the bandwidth, the higher the capacity
•
The higher the mode, the higher the capacity
Note: Disable all T1/E1 ports if there are no T1/E1 interfaces
connected. This shifts all available throughput to the Ethernet interface.
Note: If a selected combination of the Link Distance, Frame Size,
Bandwidth, and Mode parameters cannot support all the desired T1 or E1
ports, the ports that cannot be supported are automatically disabled.
Priority is placed on the T1/E1 port number. That is, the first port to be
disabled, if necessary, is the highest port number, such as Port 4 for the
standard models, and Port 16 for ‘-16’ models (assuming that all 16 TDM
interfaces are licensed for use). See T1/E1 Configuration Pages on page 69
for more information.
Link Orientation and Synchronization
Link orientation refers to the Radio A and Radio B placement in your network. Link
synchronization refers to using external or internal timing to coordinate multiple links.
For every link, one end of the radio link must be configured as Radio A, while the other
end is configured as Radio B. In single-link systems, it does not matter which end of the
system is mounted at which end of the link, and there is typically no requirement for any
link synchronization.
Link orientation and synchronization are more important for networks with site(s) where
there is more than one link of the same type or for sites using the same type of radio that
are very close to each another at one or both ends.
It can be advantageous to utilize link synchronization for collocated links. The radios
allow the use of an optional GPS synchronization kit or internal synchronization. This
synchronization controls the transmitter and receiver frame timing so that collocated
radios are transmitting at the same time and receiving at the same time. This can
substantially reduce the opportunity for self-interference. Without synchronization,
5000001
2007-06-25
26
Exalt Communications, Inc.
Exalt i-Series Installation and Management Guide
collocated radios may be transmitting and receiving at the same time, incurring near-end
interference.
Note: It is not always necessary to synchronize collocated radios. If
antennas are substantially separated or blocked from one another and/or
frequency separation tuning is used, the opportunity for near-end
interference can be eliminated.
Note: Internal and/or GPS sync features are not released for all models
as of printing. Contact your Exalt Communications representative for
details.
Radio A/B Configuration
Use the Exalt GUI to configure the radio terminals for Radio A and Radio B orientation.
Since many other parameters also need to be set, and the Exalt GUI is needed for these
configurations, this is the best way to completely configure the radio terminals.
Radios arrive from manufacture in default configuration, orientated as Radio B and
configured as shown in Table 1.

Standard models: If radio configuration is unknown, and you do not have access to a
computer and must install the radios immediately, the temporary hardware configuration
key can help to establish a link or perform back-to-back bench testing, by helping to
configure one of the radio terminals to Radio A.
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) on page 54 for details.
Temporary Hardware Configuration Key (Standard Models Only)
Use the following steps to enable the temporary hardware configuration key:
1.
Remove power from the radio.
2.
Remove anything connected to the ALARMS port.
3.
Connect the key (found in the accessory kit) to the ALARMS port.
4.
Hold down RMT button while applying power.
The LEDs toggle through the boot cycle.
Continue to hold the RMT button until the LEDs stabilize (approximately 45
seconds).
5.
Release the RMT button.
The following configurations are reset on the radio:
•
IP address = 10.0.0.1
•

•
Administration password = password
•

DIP Switch Configuration (-16 Models Only)
The -16 models have a DIP switch to allow temporary configuration for Radio A and
Radio B. See DIP Switch Settings (-16 Models Only) on page 114 for information on DIP
switch functions.
Radio Synchronization
The radio synchronization feature improves the performance of Exalt radios operating
in the same frequency band and that are collocated (such as in repeater and hub
configurations). Radio synchronization ties radio systems together to operate off of a
5000001
2007-06-25

Exalt i-Series Installation and Management Guide
common clock system, ensuring that all radios simultaneously transmit and receive, and
thus eliminating near-field interference issues and related radio system coupling.
Note: The synchronization function is not currently available on all
Exalt radio models. A firmware upgrade may be required for models
without sync if sync is desired. Contact your Exalt representative for
details.
Synchronization Modes
Synchronization can be accomplished using either an internal or external source. In
either case, one radio in the network must be defined as the primary sync source (A)
radio.
A Global Positioning System (GPS) kit from Exalt is required to implement external
source synchronization. GPS synchronization is not available on all radio models.
Contact your Exalt representative for details.
Synchronization implementation only requires one synchronization source for any
interconnected network. The system also implements a redundancy configuration to
maintain a majority of the synchronization functions in case of primary radio failure.
For internal synchronization, the primary radio is designated SYNC SOURCE. This radio
provides the master timing for all interconnected radios. SYNC SOURCE radios and
collocated radios must be configured as Radio A.
Collocated radios must be in SYNC RECIPIENT mode; they receive sync signaling from
the SYNC SOURCE, either directly or daisy-chained with other collocated radios.
Alternatively, the radio(s) can be placed in AUTO SYNC mode. AUTO SYNC
synchronizes the radios to any source provided on the SYNC IN port. However, if an
appropriate synchronization signal is unavailable, the radio becomes the SYNC SOURCE
for all connected radios.

backbones can be implemented with synchronization using these configurations. It is
typically necessary or ideal in each configuration to match the following parameters on
every radio in the network:
•
Link Distance – Match to the longest distance link in the network.
•
Frame Length – Match to the lowest frame length to optimize total system latency
(for example, for TDM networks) or match to a highest frame length to optimize user
throughput. Choose an intermediate value to compromise between latency and
throughput.
•
Mode – It is desirable, but not always necessary, to match the mode for all collocated
links.

•
Bandwidth – It is desirable, but not always necessary, to match the bandwidth for all
collocated links.
For complex networks, an Exalt engineer should review multi-link networks before
deployment as several factors can optimize the network for desired performance.
External Synchronization
Use an external GPS source as an alternative to the internal synchronization source for
system synchronization. This is ideal for links that are nearby each other, but are not
directly collocated at the same site. Figure 7 illustrates using a GPS source for the
primary synchronization at a typical site with collated radios.

Offset Timing
Manual control of offset timing is also allowed. This provides a means to delay the
synchronization signal using a user-defined offset. This is helpful when Exalt radios are
near other devices operating in the same frequency band that also use a timing source,
5000001
2007-06-25
31
Exalt Communications, Inc.
Exalt i-Series Installation and Management Guide
such as GPS. The timing source to the Exalt radios can be adjusted to match the other
radio system timing source mechanism.
Offset timing can also optimize timing intervals for repeaters and backbones. As the
distance of each link results in a unique factor for speed-of-light transmission of the radio
signal, a subsequent radio can be delayed in timing so that the overall synchronization of
radios is precisely maintained.
Offset timing can be adjusted in 1-ms intervals, from zero to the radio’s frame length
setting. For example, if using a 2-ms frame length, the offset timing can be set from zero
up to 1999 ms.
Note: Offset timing is not supported in all models at the time of this
writing. Consult your Exalt representative for details.
When Sync is Lost
If the primary sync source (for example, the sync source radio or GPS source) signal is
lost due to equipment failure, a disconnected sync cable, or other conditions, the first
radio in the daisy-chain configuration set to AUTO SYNC resumes the sync function for
the remaining connected radios.
If a radio is configured as SYNC RECIPIENT, transmission ceases if the sync signal
does not appear at the SYNC IN connector.
A radio running in AUTO SYNC (without the sync source) is said to be flywheeling. That
is, the clock is free-running off internal clocking and is no longer synchronized to any
source.
If the original sync source is restored to the flywheeling radio configuration, the
flywheeling radio attempts to synchronize to this signal without causing transmission
interruption. All interconnected radios receiving sync from the flywheeling radio also
continue to operate without interruption.
When the flywheeling radio runs independently for long periods of time, the
synchronization signal can be too far outside of the capture range of the synchronization
loop, and portions of transmission frames can be lost during the re-synchronization
process. This condition is temporary and all interconnected radios re-synchronize to the
sync source, as necessary.
For GPS synchronization, the wiring inside the Exalt radio carries the GPS signal to the
next radio cabled in the system, even when power is removed from the SYNC SOURCE
radio or during radio failures. This provides redundancy for catastrophic failure of the
SYNC SOURCE and maintains GPS synchronization. If the GPS source is lost (for
example, due to failure of the GPS unit, a disconnected cable, or satellite blockage), the
AUTO SYNC radio resumes synchronization duties for all collocated radios.
LEDs
There are two LEDs on both the SYNC OUT and SYNC IN ports. Table 3 on page 39

Installation
This section presents all tasks required to install the Exalt Digital Microwave Radio.
Mechanical Configuration and Mounting
The i-Series radios are one-piece radio 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 standard models occupy 1 rack unit
(1RU = 1.75”/4.5cm ) height in a typical telecom rack. The -16 models occupy 1.5 RU
(2.625”/6.7cm).
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. Notably,
the RF cable connector may require significant clearance for the bend radius of the
coaxial cable assembly. Use a properly specified 90º RF connector to minimize clearance
requirements, which may be necessary in enclosure implementations. All RF connectors,
cables, and adapters must be rated for operation within the radio’s frequency range
(2400–2483.5 MHz for EX-2.4i; 4940-4990 MHz for EX-4.9i; 5250–5850 MHz for EX5i). 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)

The rack mounting brackets accommodate identical mounting configurations as shown in
the previous figures, and can be mounted three different ways with respect to the vertical
orientation in the rack:
1.
Projecting down, using one full rack space and half of the space below, and leaving
a half-space gap below.
2.
Projecting up, using one full rack space and half of the space above, and leaving a
half-space gap above.
3.
Centered within two spaces, with ¼ rack space gap above and below.
Two radios mounted in the same rack can be mounted in adjoining spaces, utilizing a
total of three rack spaces.
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.
Caution: 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.

RMT (Remote) Button
The RMT button is the only external control on the radios. This button allows easy and
quick evaluation of the status of the remote-end radio. Press and hold the button and,
while held, all local-end status LEDs (LINK, STATUS, Radio A) represent the status of
the LEDs on the remote-end radio. In addition, the RSL voltage represents the remoteend voltage.
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 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.
Power
The radio requires a DC power source within specifications. The DC can be provided
from a DC battery source, central lab/rack supply, or from the supplied AC adapter.
Note: Read this section completely before applying power.
Terminating the RF Connector
Before applying power, the device’s RF connector must be properly terminated into a 50Ohm 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.
5000001
2007-06-25
41
Exalt Communications, Inc.
Exalt i-Series Installation and Management Guide
•
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 (~2400 MHz for the EX-2.4i; ~4950
MHz for the EX-4.9i, ~5700 MHz for the EX-5i), and rated for a minimum of 1W
input power. Examples include:
¶ Broadwave Technologies P/N 352-103-xxx
¶ Bird 2-A-MFN-xx
¶ JFW Industries 50FP-xxx-H6-N
AC Power
The AC adapter easily connects to the device. The AC rating of the adapter accepts most
standard voltages and frequencies worldwide. Refer to the input voltage requirements
stated on the label affixed to the adapter to ensure that the adapter can be used with the
AC mains supply.
The AC plug outlet provided with the adapter may need to be replaced to match the
country configuration. The adapter cable uses a standard connector for this cable for use
of a pre-wired cable appropriate to the outlet configuration. If the appropriate cable is not
available, the existing AC plug end can be severed and a replacement plug affixed.
Consult a qualified electrician for this activity.
Do not plug the adapter into the mains power. First, verify that the RF connector is
properly terminated (see Power on page 41), and then plug in the radio-side connector
from the AC adapter to the radio. If the AC mains can be turned off using a switch,
disable the power, plug the AC side of the adapter into the AC mains socket, and then
enable power to the circuit. If the AC mains cannot be turned off, plug in to the AC main
socket to apply power.
Verify that the radio is active by observing LED activity. All LEDs on the radio flash at
initial power cycle.
It is strongly encouraged that the AC mains supply be fused or on a separate breaker to
ensure against over-voltage and/or over-current situations and to provide some form of
protection to the radio electronics and other devices connected to the same supply. In
addition, if the AC power is subject to significant spikes or variation, power conditioning
is a worthwhile investment, as the quality of mains power may have a direct impact on
the device operation, performance and/or reliability. An Uninterruptible Power Source
(UPS) or other form of battery-backed system protects against brown-out and black-out
conditions, and condition the power presented to the adapter.
Evaluate the opportunity for lightning or other similar surges to be present on the
powering system, including the ability for surges to couple to the power wiring system. If
an evaluation indicates that there is a potential likelihood for these conditions to occur,
additional surge protection is recommended for the input power wiring, especially to
protect the radio electronics between the adapter and the radio’s DC input connector.
The above statement is similarly true for every wired connection to the device. While the
configuration for surge suppression or line conditioning is of a different type for each
5000001
2007-06-25
42
Exalt Communications, Inc.
Exalt i-Series Installation and Management Guide
kind of signal interface, the opportunity for damage to the device, loss of
communications and property is significant. In some cases, there can also be a risk to
human life by not protecting against lightning entering a building through wiring or
improper grounding. If you do not have experience in this type of installation practice,
consult a qualified electrician and/or telecoms professional during the installation and
wiring of the equipment.
DC Power
The device accepts DC power within the voltage specifications. The DC voltage input
accepts either 20-60VDC. 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.
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.
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.
Figure 16
DC connector
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 on page 41. 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.
See Power on page 41 regarding fusing, breakers, lightning protection, surge protection
and power conditioning. Follow these recommendations for a DC supply.
Reset to Critical Factory Settings
If necessary, the radio terminal may be reset to critical factory settings. This may be
necessary if the IP address and/or passwords for the system are not known. All other
configurations are left at their current settings. If a complete default factory configuration
is desired, load the Default Configuration File into the system, as described in System
Configuration Page on page 64.
The following parameters are configured after a reset to critical factory settings:
•
IP Address = 10.0.0.1
•
IP Mask = 255.0.0.0
•

Antenna/Transmission System
This section provides general guidance to the mounting and connecting of the RF
transmission system, consisting 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.
The antennas permitted for are identified in Tables 10 and 11.
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 self-interference from nearby or
collocated systems operating in or near the same frequency band.
Warning: Mount the antenna in a restricted area and in a manner
preventing long-term human exposure to the transmitted RF energy. To
comply with FCC and Industry Canada regulations, the minimum safe
distance from the antenna for continuous human exposure for the EX-2.4i
models is 10 feet (3m), 39 inches (1m) for the EX-4.9i, and 10.5 feet
(3.2m) for the EX-5i models.
The antenna structure must be secure and safe with respect to the mounting of the
antenna, transmission system weight, 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.
5000001
2007-06-25

Exalt Communications, Inc.
Exalt i-Series Installation and Management Guide
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.
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 use coaxial transmission line for the connection between the antenna
and the radio device. 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.
Generally, 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.
In some cases, the choice of transmission line is not coaxial cable, but is instead airdielectric waveguide. This is an expensive solution and is generally not necessary, but
may be required for very long transmission line runs, and/or very long link distances,
and/or for systems requiring extremely high reliability.

Digital Microwave Radio.

There are several other brands and models of transmission line that are perfectly
acceptable. However, for extremely long transmission lines and/or extremely long radio
paths, it may be necessary to use waveguide transmission line instead of coaxial
transmission line. In these cases, waveguide type EW20 is recommended for EX-2.4i
models (0.45dB/100ft. loss at 2.4GHz), and type EW52 for the EX-4.9i and EX-5i
models (1.2dB/100ft. loss at 5.8GHz, 1.35dB/100ft. loss at 5.3GHz).
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,
transmission line allows for N-type male connectors and antennas have N-type female
connectors. For waveguide, the waveguide flange can typically accommodate a direct
adapter to an N connector, or alternatively, the antenna can be purchased with a direct
waveguide connection. But often a flexible coaxial jumper is required to connect between
the waveguide and antenna, as waveguide is generally inflexible and can be mechanically
challenging to align to the exact antenna connector location.
If possible, connect the primary transmission line directly to the antenna. It is desired to
have the fewest possible pieces of transmission line in the system, to minimize losses and
points of failure from connectors. The antenna can typically accommodate a direct
connection if planned in advance. Use a 90ºadapter for the connection to the antenna, if
necessary, but confirm that all connectors and transmission lines are properly specified
for the operating frequency with minimum loss, proper impedance (50 Ohm) and proper
VSWR characteristics.
Transmission line connector termination is a critical element of the installation. Many
‘factory built’ RF transmission lines do not provide the proper characteristics for proper
transmission, despite their published specifications, often due to the fully or semiautomated process of factory termination, which may not have considered the frequency
of your system. When buying pre-terminated transmission line, it is strongly advised to
obtain the documentation of test measurements on the connected transmission line
showing that the loss characteristics and VSWR are within the specified limits
specifically at your operating frequency. In addition to factory-built transmission line,
self-terminated transmission line can suffer the same issues.
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.

Exalt i-Series Installation and Management Guide
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 excess of transmission line near the
antenna to accommodate both the need for extra slack as the antenna is loosened and
moved for the alignment process, and to accommodate a drip loop for the transmission
line and the initial transmission line securing hardware and grounding near the antenna.
In addition, the transmission line is typically very stiff, and can provide undue pulling
force on the antenna connector. Take care to align the cable with the connector so that it
does not provide any torque or strain on the connector.
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 overbent 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.
The opposite end of this primary transmission line typically terminates at the building or
enclosure egress point. 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.
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 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.
5000001

Exalt i-Series Installation and Management Guide
The following lightning arrestors are examples of proper devices for Exalt Digital
Microwave Radios:
•
Polyphaser AL-LSXM
•
Andrew BB-BNFNFE-26
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 cable. In some cases, a short flexible jumper
allows ease of connection to the radio’s RF connector. A properly specified 90º connector
can often eliminate this need. 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.

Exalt i-Series Installation and Management Guide
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.
•
ExaltGUI 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
5000001
2007-06-25
50
Exalt Communications, Inc.
Exalt i-Series Installation and Management Guide
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.
•
RF/DC coupler
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. See DC Coupler for Antenna Alignment on
page 107 for more information
•
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 is no other means
available. If this method is required, refer to Exalt Graphical User Interface (GUI) on
page 54. 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.

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.
Connect to the Radio with a Serial Connection
For serial interface to the CONSOLE port, on your PC, PDA, dumb terminal, or any
other device with a serial interface and text input capabilities, use Hyperterminal or a
similar application with the following settings:
Bits per second:
9600
Data bits:
Parity:
None
Stop bits:
Flow Control:
None
Use a standard straight-through serial cable to connect between most computer serial
ports and the Console port on the radio. A null modem cable is not properly wired for this
interface. See Interface Connections on page 109 for wiring details.
After establishing the serial connection, press ENTER to display the login prompt.
Connect to the Radio through a Telnet Connection
Use the following steps for a Telnet connection to the radio through the ETHERNET
AUX port using Windows:
1.
Open a command prompt, or MS-DOS prompt shell (Start>Run>cmd).
2.
Type C:\>Telnet  at the command line of the command prompt
window.
The default IP address is 10.0.0.1
Note: You can reset the default address to a different address through
serial CLI using the Console port, or back to the default address by radio
reset.
Note: Your computer must be on the same IP subnet as the radio to
use the Telnet function.

Exalt Graphical User Interface (GUI)
The Exalt GUI is the primary user interface for configuring and troubleshooting the radio
and radio system. A computer or hand-held device with a conventional HTML browser
and Ethernet port is required. Microsoft Internet Explorer is the preferred browser.
Netscape, Mozilla, and Firefox are also supported.
Preparing to Connect
If the radios are new, both radios are preconfigured as Radio B, and have the same IP
address. The initial priority is to configure one radio to Radio A and assign different IP
addresses, unique to each radio.
There are two ways to change the IP address:
1.
Use the CLI interface through the console port (serial), as described in Command
Line Interface (CLI) on page 52
2.
Connect to the GUI using the default IP address (10.0.0.1), and change the IP
address through the GUI interface.
Note: If the radio’s current IP address is unknown, use the CLI
interface through the console port to retrieve it and/or change it. Or
perform a complete radio reset as described in Reset to Critical Factory
Settings on page 44.
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).
There are three ways to configure a radio as Radio A:
1.
Use the temporary hardware configuration key, as discussed in Temporary
Hardware Configuration Key (Standard Models Only) on page 28.
5000001
2007-06-25

2.
Use the front panel DIP switch, as discussed in DIP Switch Configuration (-16
Models Only) on page 28.
3.
Connect to the GUI and change the configuration, as discussed in this section
(preferred).
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 Terminating the RF Connector on page 41).
•
Apply power to the radio (see Power on page 41).
Note: Do not connect the radios in a back-to-back configuration. If the
radios are set to their factory default settings, both radios are configured as
Radio B and cannot communicate. Both radios also have the same IP
address, which causes IP address conflicts.
Use the CONSOLE port and CLI interface to configure the IP address to match the
accessing computer or connect to the ETHERNET AUX port to the computer’s Ethernet
port.
Note: The IP address subnet of the accessing computer must match the
radio’s IP address subnet to connect using Ethernet (see Preparing to
Connect). Either change the computer’s IP address to match the radio, or
use the CLI to change radio’s IP address to match the computer.
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.
1.
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.

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

The link may be lost and unrecoverable through GUI control. If the link is lost
due to reduction of Radio Transmit Power, travel to the radio location(s) may be
required to reset the value.
•
Set the Bandwidth parameter to the designed level. The value of this is determined in
the design/engineering stage. The Bandwidth parameter must also match at both ends
of the link. In conjunction with the Mode parameter, the Bandwidth parameter
directly relates to the capacity, latency, and the number of TDM circuits supported.
The transmitter and receiver bandwidth are modified using this parameter, making it
critical that it be set with respect to the local RF noise and interference profile, and/or
in relation to any multi-link network design.
Note: Changing Bandwidth will temporarily interrupt traffic. The
Bandwidth parameter must match at each end. Adjust the far-end radio
first, and then the near-end radio. Changing Bandwidth changes the
radio’s threshold. A narrower bandwidth has better threshold performance
and improved interference immunity, therefore if changing to a wider
bandwidth, there is an opportunity that the link may be lost and
unrecoverable through GUI control. Check the available fade margin and
interference profile to determine if the impact to threshold and increased
bandwidth is acceptable to maintain the link and the desired performance.
If the link is lost due to increasing the Bandwidth parameter, travel to the
radio location(s) may be required to reset the value.
•
Set the Mode parameter to the designed selection. The value of this setting is
determined in the design/engineering stage. The Mode parameter must match at both
ends of the link. In conjunction with the Bandwidth parameter, the Mode parameter
setting directly relates to the capacity of the system, as well as critical RF parameters,
including receiver threshold, carrier-to-interference ratio, and in some cases,
maximum radio transmit power.

Note: Changing Mode will temporarily interrupt traffic. The
Mode setting must match at each end. Adjust the far-end radio first, and
then the near-end radio. Changing Mode changes the radio’s threshold,
carrier-to-interference ratio, and also may have impact on the Radio
Transmit Power. A lower mode has better threshold performance and
carrier-to-interference ratio, and in some cases, higher output power,
therefore if changing to a higher mode (for example, from Mode 1 to
Mode 2), there is an opportunity that the link may be lost and
unrecoverable through GUI control. Check the available fade margin and
interference profile, and determine if the impact to RF performance is
sufficient to maintain the link and desired performance. If the link is lost
due to increasing the Mode parameter, travel to the radio location(s) may
be required to reset the value.
•
Set the RF Frequency parameter to the designed point. The value of this setting is
determined in the design/engineering stage. RF Frequency must match at both ends of
the link. It may be critical to set RF Frequency with respect to the local RF noise and
interference profiles, and/or in relation to any multi-link network design.
The frequency selection section includes the ability to select from either the complete
list of frequencies (“All”) that can be tuned for the selected band and bandwidth, or a
pre-selected list of non-overlapping center frequencies (“Preferred”) that Exalt
determined provides the most flexible collocation opportunities for large networks of
Exalt radios
For the EX-5i families, the frequency selection section includes a band selection
button that must be enabled for the frequency band of operation for which the link
was engineered. In some cases, some bands may not be selectable due to regulatory
constraints.
Note: Changing RF Frequency will temporarily interrupt traffic.
The RF Frequency parameter setting must match at each end. Adjust
the far-end radio first, and then the near-end radio. If the RF Frequency
parameter is changed to a frequency with interference, the link may be lost
and unrecoverable through GUI control. If the link is lost due to changing
the RF Frequency parameter, travel to the radio location(s) may be
required to reset the value.
•
Set the Endpoint Identifier so that one end of the link is set to Radio A and the
opposite end set to Radio B. In single-link networks, it is unimportant which
end is designated A or B. In multi-link networks, however, it may be
important to orient the links so that at any collocation site (where there are
multiple radios of the same type at the same site), all radios are set to the same
Endpoint Identifier (A or B). See Link Orientation and Synchronization on
page 26.
Note: Changing Endpoint Identifier parameter requires a reboot of the
radio to take effect. The reboot temporarily interrupts traffic.

•
Set the Link Distance parameter to the range that is equal to or greater than the actual
link distance. The value of this setting is determined in the design/engineering stage.
Note: Changing Link Distance parameter will temporarily
interrupt traffic. The Link Distance setting must match at each end and
must not be less than the actual link distance. Adjust the far-end radio
first, and then the near-end radio. If the Link Distance parameter is
changed to a setting less than the actual distance, the link may be lost and
unrecoverable through GUI control. If the link is lost due to this situation,
travel to the radio location(s) may be required to reset the value. If the
Link Distance parameter setting is set to a distance unnecessarily higher
than the actual link distance, the radio may have substantially reduced
performance with respect to throughput and latency.
•
Set the TDD Frame Size parameter to the designed level. The value of this setting is
determined in the design/engineering stage. The TDD Frame Size parameter must
match at both ends of the link. The TDD Frame Size parameter setting directly relates
to the capacity, latency, and number of TDM circuits that can be supported over the
given link distance. In multi-link networks, especially where there are collocated
links, it is also important to set all radios to the same TDD Frame Size setting to
avoid self-interference. Note that the GPS or internal synch function may be
necessary for these networks. See Time Division Duplex (TDD) Factors, Link
Orientation and Synchronization, and Radio Synchronization for more information.
Note: Changing the TDD Frame Size parameter will temporarily
interrupt traffic. TDD Frame Size parameters must match at each
end. Adjust the far-end radio first, and then the near-end radio. If the TDD
Frame Size parameter is set to a value that cannot be supported for the link
distance, the link may be lost and unrecoverable through GUI control. If
the link is lost due to this situation, travel to the radio location(s) may be
required to reset the value.

The External Alarm Inputs parameter can be ignored unless connecting external
alarm sources to the radio for monitoring the status of these external alarms through
the radio management system (see Interface Connections on page 109).

Ethernet Interface Configuration Page
This page allows the administrator to set the muting, alarm, and duplex settings of both
the ETHERNET MAIN and AUX connections.
It also allows determination of the management information for in-band (carried over the
air and available from both the MAIN and AUX connectors on either end of the link) or
out-of-band (not carried over the air and only available from the local AUX connector).
Figure 26
Ethernet Interface Configuration Page
Muting the MAIN connection is desirable when connected equipment senses Ethernet
signaling and makes decisions (such, as spanning tree protocol enable) based on the
presence or lack of presence of the Ethernet signal. If the MAIN connection has muting
enabled, the port mutes when the link is not active.
It may be desirable to disable the alarming of the AUX connector if it is not used.
Set the Ethernet interfaces on the radio and connected equipment to 100/full-duplex for
best performance. If the Ethernet ports are set to auto-negotiation, poor throughput
performance may be a result, as well as intermittent disconnections of the Ethernet
connection.

T1/E1 Configuration Pages
These pages allow the administrator to selectively enable or disable the T1 or E1 circuits,
one at a time. For enabled T1/E1 circuits, additional configuration, including loopback
functions, are available. Disable the unused T1 or E1 so that the alarms are turned off and
more throughput is allocated to the Ethernet interface. Every enabled T1 or E1 input,
even if there is no T1 or E1 signal present, reduces the aggregate throughput of the
Ethernet interface by roughly 3Mbps (for T1) or 4Mbps (for E1).
This page toggles between T1 and E1, as required, by clicking the Set to T1 or Set to E1
button. A warning displays that a reboot is necessary, and the radio reboots if the
administrator continues. This will interrupt traffic. It may be necessary to re-login to the
radio after the reboot completes. T1/E1 mode self-coordinates across the link if the link is
active. This means that it only needs to be set while connected at one end. In addition,
enabling and disabling T1/E1 circuits also self-coordinates across the link if the link is
active. If a link is not active and T1/E1 enabling is a mismatch when a link is first
created, the Radio A configuration for T1/E1 enabling supersedes the settings on the
Radio B configuration, and changes the settings on Radio B.
Note: Certain combinations of the TDD Frame Size, Link Distance,
Mode, and Bandwidth parameter settings limit the number of T1/E1
circuits that can be carried by the radio. In these cases, certain fields on the
T1/E1 Interface Configuration pages are not available, starting with the
highest port number. For example, for a 4x T1/E1 radio version, if only
three (3) circuits can be carried, port 4 is not available for configuration
and is disabled. If only two circuits can be carried, both ports 3 and 4 are
not available. Increasing the TDD frame size and Mode parameters, and/or
increasing the Bandwidth parameter results in an increase in the supported
number of T1/E1 circuits. For ‘-16’models, the highest number channels
that are configurable (based on the currently installed license key) are
disabled if they cannot be supported with the current settings.
T1 Interface Configuration Page
This page allows the administrator to enable/disable each individual T1 channel, set the
Line Build Out (LBO), Line Code (either AMI or B8ZS), and AIS enabling/disabling for
each input. If enabled, the radio places an AIS code on the output of the associated
interface if and when the link fails or when there is no T1 signal available from the far
end to provide the user at the local end. Loopback controls are also provided (see T1/E1

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 29 and Figure 30).

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 on page 76).
Up to three types of files can be downloaded: configuration, radio firmware, and MIB.
The MIB file refers to the Management Information Base related to the Simple Network
Management Protocol (SNMP) function, and is only available on models which support
SNMP. See Simple Network Management Protocol (SNMP) on page 77 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). See File Activation Page on page 76.

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 downloaded 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 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

Simple Network Management Protocol (SNMP) Configuration
Use SNMP to manage networked devices and execute the following functions:
•
GET: Obtain information from the device, such as a configuration setting or
parameter.
•
SET: Change a configuration setting on the device.
•
TRAP: The device proactively informs the management station of a change of state,
usually used for critical alarms or warnings.
Note: Currently the SNMP implementation does not support TRAP
functions. For critical alarms, use the GET command for specific alarm
conditions.
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.
Note: Currently not all EX-series radios implement SNMP. Check the
software release notes to verify that the function is available. Generally,
the radio supports SNMP when MIB files are listed on the File Activation
Page.
The SNMP MIBs are organized similar to the GUI. Become familiar with the GUI before
using the SNMP function.

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

•
The Internal Fan alarm monitors all three internal fans. The radio only requires that
one fan be operational for full-specification performance. The additional fans are
provided for redundancy and to increase overall reliability. If one or two fan alarms
are yellow or red, it is prudent to plan to install a spare radio at the earliest
opportunity and return the radio for repair (RMA authorization required). If all three
fans are in alarm, the radio must be taken out of service immediately, as damage may
occur to the internal electronics, especially in hotter environments or where thermal
exchange from neighboring equipment exists.

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, unless the fans in
the unit are also in alarm, in which case, the fans are the likely cause.

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 36
•
Performance page
The Current BER field indicates the current bit error rate of the link. If the link is
operating perfectly, this should indicate zero. Generally, the link should remain at a
BER less than 1x10-6 (1 bit out of every million bits errored). This is the threshold
performance specification and the standard to which the link was engineered.
However, radio links can and are affected by weather, interference, and other external
sources and will occasionally have a higher error rate. A link remains operational
unless the BER exceeds 1x10-3 (1 bit out of every hundred bits errored). Consult the
link design engineer for an understanding of the predicted error rate of the radio link
as it has been designed. Many applications are unaffected by bit errors, but TDM
circuits (for example, T1 or E1) are more sensitive. Also, if the link operator is
providing a service guarantee, this value may need to be monitored or examined in
cases of service issues. The behavior of BER in relation to other alarms or
measurements and external events can be very helpful in troubleshooting activities.

•
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.
•
Errored Seconds (ES) indicates the total number of seconds that occurred where there
was at least one bit error since the last time that the radio statistics counter was reset.
Generally, ES are not a significant concern, so long as they are not continuous or
above the anticipated performance based on the original link engineering goals. If ES
are continuous or at a high rate, this is normally an indication of poor link
performance due to poor RSL or interference, or severe impact by weather or other
environmental factors. However, similar to the performance factors previously listed,
ES can and will occur in any radio link. Once again, consult the link engineer to
determine the original design goals, and compare actual performance to these
expectations to determine if any improvements are necessary or if other problems
may be causing excessive ES.
Note: Unavailable Seconds do not register as ES. In other words, the
ES counter counts all seconds that are errored NOT INCLUDING the
seconds that were classified as unavailable. The total number of seconds
with errors or outages is the sum of ES and Unavailable Seconds.
•
Unavailable Seconds (also called UAS) are similar to ES, but this counter keeps track
of every second where the bit error rate equals or exceeds 1x10-3, as well as any
seconds where there is a complete loss of radio communication, over the period since
the last counter reset. If Unavailable Seconds are continuous or at a high rate, this is
normally an indication of poor link performance due to poor RSL or interference, or
severe impact by weather or other environmental factors. However, similar to the
performance factors listed above, Unavailable Seconds can and do occur in any radio
link. Consult the link engineer to determine the original design goals, and compare
actual performance to these expectations to determine if any improvements are
necessary or if other problems may be causing excessive Unavailable Seconds.
•
Minimum RSL indicates the worst (lowest) received signal level that occurred since
the last counter reset. It is helpful to know if the RSL dropped significantly from the
normal level, or has reached a level near or below threshold.
•
Minimum RSL Timestamp indicates the date and time when the Minimum RSL
occurred. This is helpful for general troubleshooting, and especially comparing to
items in the event log or diagnostic charts from the same time period.

•
Maximum RSL indicates the best (highest) RSL that occurred since the last counter
reset. This indicates the best performance of the radio link, which is normally equal to
the installed value, and is usually the designed value.
•
Time Since Reset indicates the amount of time passed since the last counter reset.
This helps to quantify the seriousness of other statistics, such as ES and Unavailable
Seconds, if there have been high numbers of ES and/or Unavailable Seconds over a
relatively short period of time.
Each end of the link statistics on this page can be independently reset using the Reset
Statistics button for the local or remote radio. It is good practice to reset the statistics at
the time that the link is commissioned (after all antenna alignment is complete and stable
RSL at designed levels is achieved, and no more system reboots are anticipated). Make a
habit of viewing this page regularly, make records of the performance, and reset the
statistics so that the counters can more precisely pinpoint issues.
Note: Resetting statistics from one end also resets the statistics for the
same radio at the opposite end. That is, if the Local statistics are reset,
logging into the remote end shows the Remote statistics on that end
(which is the local radio in the first condition) as being reset at the same
time.

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.
It is also useful to help determine if changes in radio temperature are occurring, and if
they are having any impact on RSL or BER. If the radio is mounted in an
environmentally controlled location, this has less relevance. However, temperature
monitoring can be helpful to ensure that the radio is operating within specifications.

Troubleshooting
This section provides information regarding troubleshooting of common issues and
alarms on these radios. 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 on page 85).
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-to-back Bench Testing on page 104) is very important to determine
if radio hardware is operating properly and eliminate many variables in the
troubleshooting process.
If a back-to-back bench test fails, then the radio hardware is either broken or the radios
are improperly configured. Upgrade the radio to the most current release of firmware,
and/or reset the radio to its critical factory settings, following the quick start guide
instructions and those in Configuration and Management, helps to confirm if
configuration issues cause failure. The most common issues with microwave radio links
are:
•
An improperly terminated RF cable
•
Multipath propagation
•
RF interference
•
Path obstruction
•
Misaligned antenna
•
Faulty antenna
•
Improper grounding
•
Insufficient link margin in the design/implementation
•
Moisture in the transmission system (antenna feed and/or RF cable)

If the radio link has been operating without issues and is exhibiting new poor
performance behavior or becomes completely inoperative, the troubleshooting process
should pay close attention to any conditions that may have changed between the time
when the system was working without issue and the time when the issues started.
Also, it can be helpful to compare some performance parameters of the system before and
after the presence of issues. Often the source of the issues can be determined by
thoughtful consideration of changes, such as:
•
Changes in weather, including high winds
•
Changes made to the radio equipment, transmission system, or connected equipment
•
New radio systems or electronic equipment the nearby radio or transmission system
•
New construction nearby either end of the link, or along the path
•
Tree growth, flooded fields, or changes in rivers/lakes along the path
Verify that configurations are set as follows:
•
RF matches at each end of the link
•
Bandwidth matches at each end of the link
•
Link distance matches at each end of the link
•
TDD Frame Length matches at each end of the link
•
Endpoint Identifier is different at each end of the link (one end Radio A, one end
Radio B)
•
Ethernet interfaces are enabled, as desired
•
AUX Ethernet is set for in-band or out-of-band NMS, as desired
•
T1/E1 enabling matches at each end of the link
•
Link security key matches at each end of the link
Also, use the ExaltCalc tool in the design phase to determine the optimum setting for the
Bandwidth and TDD Frame Length parameters for the given link distance, and provides
guidance to the expected RF link performance, as well as throughput, latency, and
number of supported T1/E1 circuits.
Typical Indications of Issues
In many cases, microwave radio users do not notice changes or degradation to the radio
system until the radio system fails completely or becomes highly errored or significantly
intermittent. However, regular management of the radio system can help indicate changes
in performance that have not yet impacted user performance, but may impact
performance at a later date if left unchecked or unaddressed. The administrator can use
this as an opportunity to be proactive and monitor the radio link performance regularly,
watching for unexplained or unexpected changes in performance and trends in
performance changes.

Exalt i-Series Installation and Management Guide
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 Exalt Customer Care, the
process to rectify the system is much more expedient due to the in-depth knowledge
related to the implementation and the RF environment.
Improper RF Cable Termination
Improper RF cable termination is a very common problem. In many cases, this is a
problem that occurs during installation and is not a problem that suddenly appears.
However, if cables are moved or flexed, especially near the termination points, and radio
errors, changes in RSL, or other performance issues occur, this is a certain sign of this
issue.
Another relatively easy method to test for this condition is to decrease the output power
of the radio system (at each end, one end at a time). A poor RF cable termination may be
reflecting too much RF energy back into the radio system, and reducing output power
reduces the reflected energy at a faster rate than the transmitted energy towards the far
end. Be careful not to reduce the output power to the point where the radio’s threshold is
reached. Typically, a reduction of just 3 to 6dB is enough to determine if this is the issue.
If the reduction of output power clears the error condition, this is the likely cause.

Exalt i-Series Installation and Management Guide
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 a signal level similar to the level of the signal of your
radio system.
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.
Note: The EX-2.4i and EX-5i operate in license-exempt bands.
Microwave ovens, wireless Internet devices and cordless phone
technology may also use this frequency band. It may be necessary to
separate the radio chassis, cabling system and antenna from these devices.
RF interference, like most other causes of problems, is indicated by significant bit errors
and/or system outages.
One means to determine presence of interference is the use of a spectrum analyzer that
covers the same range as the radio system. A professional RF engineer can use a
spectrum analyzer to locate sources of interference, measure these sources, and determine
potential remedies to take to operate in the presence of interference.
If a spectrum analyzer is not available, the radio’s RSL port can help determine RSL
levels of interfering signals. By turning the far-end radio off, the residual RSL measured
5000001

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.
The EX-2.4i and EX-5i families provide considerable flexibility to tune to different
frequencies across the bands within which they operate. This is the easiest method to use
to try to avoid existing interference. In addition, the occupied bandwidth of the radio can
be reduced. This, along with re-tuning, can be very effective, however throughput is
reduced.
Repositioning the antenna and/or changing polarization, or upgrading the antenna to a
higher gain, and/or using a high-performance antenna, are all secondary means that can
be used. It may be necessary to perform combinations of both radio changes (retuning,
occupied bandwidth reduction) and antenna system changes (position, polarization,
upgrade).
The EX-4.9i radio operates under licensed regulations. If interference is suspected, the
local frequency coordination organization, or other users of the spectrum should be
consulted before re-tuning the radio to a different frequency channel.
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.
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. Physical inspection can be
helpful, and if changes to the weatherproofing occur (such as cracks), the
weatherproofing must be replaced before it leaks.

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:
1.
Basic test (test general operation)
2.
Specification performance verification
Basic Test
The basic test is a simple test of radio functionality. It verifies that the radios are properly
configured to communicate to one another, and verifies general radio performance as
operational.
For the basic test, the following items are needed:
•
Radio pair
•
Powering source
•
RF interconnect cable(s) (any length – short is best)
•
Fixed or variable attenuation, between 60 and 90dB (note: attenuation for basic test
does not to be calibrated or precise)
•
Computer/terminal with either serial or Ethernet port (helpful, but not necessary)
¶ If no computer is available, use the temporary hardware configuration key or DIP
switch, depending on radio model (see Radio A/B Configuration on page 27)
Connect the items as follows:
1.
Connect attenuation and (known-good) RF cable(s) between radio pair, shown in
Figure 41.
2.
Configure one radio as Radio A; the other as Radio B
3.

Basic back-to-back bench test configuration
After connecting and powering on, observe the front panel LEDs to verify that the LINK
and STATUS LEDs are green. If so, the radios are communicating and all radio-related
alarm conditions are normal.
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 41, 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:
1.
RF output power
2.
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.

Exalt i-Series Installation and Management Guide
Use the volt meter to measure RSL in both directions. The RSL measured value should
match the appropriate value according to the inserted attenuation, such as:
RSL = RF Output Power – cabling losses – total attenuation
Verify output power by adjusting output power using the Exalt GUI (in administration
mode) and evaluate the corresponding change to the RSL measurement.
For threshold testing, the key is to insert a measured amount of loss that is close to, but
not exceeding the radio’s specified system gain. System gain is the difference between
RF output power and receiver threshold. At your selected modulation and bandwidth
settings, determine the specified threshold performance, and choose a value of
attenuation (including cable losses) that adds to roughly 5 to 15dB less than the system
gain.
For example, for the EX-2.4i, if the threshold for your measurement is -85dBm, the
output power is +27dBm, so the system gain is 112dB. Choose a value of total
attenuation in the range of roughly 100–105dB. Once this attenuation is inserted, verify
RSL readings as in the first step, and then, using the GUI, reduce radio output power in
1dB steps until the receiving radio (the one whose output power not being adjusted) Link
LED turns from green to yellow. This indicates that threshold has been reached. At this
point, verify the equation for system gain using the new output power level setting and
verify that the threshold performance is meeting or exceeding the published specification.
Note: Due to the variation of measurements and accuracies involved
in this test, you may read a measurement that is 1dB to as much as 2dB off
of the expected value. It should be of no concern unless the value is more
than 3dB worse than expected.
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.
Perform threshold measurement tests for all combinations of bandwidth and mode
(modulation) being used–especially when troubleshooting. It should not be necessary to
vary center frequency, as this does not have any appreciable impact on system gain
performance, however, try any setting combination to gain confidence in the radio
performance parameters.

DC Coupler for Antenna Alignment
One challenge associated with an all-indoor radio construction is the alignment of the
antennas. It can sometimes be challenging to place the radio near the antenna alignment
personnel, and can also be challenging to run a separate set of wires for the voltmeter to
be in view of the alignment personnel. If any of the conventional methods mentioned in
the manual are difficult to achieve, one of the simplest methods to use is to employ the
use of a DC coupling system as a temporary test configuration exclusively for the
purpose of aligning the antennas.
This type of system simply couples the DC voltage associated with RSL measurement at
the radio location, over the RF transmission line, up to the antenna port.
Warning: Remove all DC-blocked lightning arrestors in the
transmission system prior to applying the DC coupler system.
Failure to do so can result in electric shock and/or damage to the
lightning arrestors and/or other equipment.
Required Items
The following items are needed for the DC coupling system, per radio end (double the
quantities of these items for a complete link for simultaneous use at both ends):
•
2ea DC couplers: mini-circuits ZNBT-60-1W
•
1ea BNC male-male extension cable: Pomona 2249
•
1ea BNC female-to-mini Bantam (stackable Pin-tip plugs): Pomona 3221
•
1ea BNC female-to-banana male: Pomona 5268*
•
1ea digital volt meter
*This type of plug is typical for most professional hand-held digital volt meters (DVMs).
However, verify that your DVM can accept this type of Bantam connector. If not, a
different part number or adapter may be required to connect to the DVM.
Interconnections
Connect the items as shown in Figure 42. For the coupler installation, ensure that the DC
side of the coupler is facing away from the radio and away from the antenna – towards
the RF transmission line system. Using the BNC adapters and cables, attach the radio end
DC coupler to the RSL port on the radio, and the antenna end DC coupler to the DVM
that the antenna alignment personnel will use.
The DC voltage from the RSL port is now coupled to the transmission line system
between the radio and the antenna, and is available at the antenna location. This allows
the antenna alignment personnel to view the DVM output directly while adjusting the
antenna.

device.
Depending on the settings of in-band or out-of-band NMS, both the MAIN and AUX
ports can access the far-end radio (if in-band) or not (out-of-band). In the case of out-ofband setting, only the AUX port can access the GUI, while only the MAIN port carries
Ethernet traffic across the link.

DIP Switch Settings (-16 Models Only)
The ‘-16’ models incorporate a front panel DIP switch. Use the DIP switch for
emergency configuration or restoration for installations where there is no computer
available for complete radio configuration. Only use the DIP switch for temporary
purposes, for the purpose of a bench test or antenna alignment. Use the Exalt GUI for
complete system configuration, as required before final system deployment.
The DIP switch is only read when the critical factory reset procedure is implemented (see
Radio A/B Configuration on page 27 and Reset to Critical Factory Settings on page 44).
That is, when the RMT button is pressed and held during power up, and held through the
boot cycle (approximately 45 seconds, until LED behavior stabilizes). If changes are
made while the radio is already powered or when power is not applied, the changes are
not executed until a reset is executed.
Figure 50 depicts DIP switch positions 1 through 8, left to right, when facing the front
panel. Also, the switch is considered in the ‘One’ position when it is toggled upward, and
in the ‘Zero’ position when it is toggled downward (default).

Dynamic Frequency Selection
Dynamic Frequency Selection (DFS) may be required by regional legislation in some
frequency bands in order to avoid causing interference to radar systems. Prior to the start
of any transmission, the device equipped with DFS monitors the spectrum and is not
permitted to transmit on a part of the spectrum that is already in use for radar
transmissions for a period of 30 minutes. During operation of the device, the spectrum is
continually monitored by the DFS to detect if radar begins transmission on a frequency
that is being used by the device to transmit on. If the DFS software detects radar, the
device must move off channel within a specified time period so that the device
transmission does not interfere with the radar transmission. The device equipped with
DFS is required to stay off that part of the spectrum for a minimum of 30 minutes, after
which time the device may then check the spectrum for radar transmissions and begin
transmitting if no radar is detected.
Antennas
The following Tables list antennas recommended for use with the i-Series radios. The
EX-4.9i may use any antenna. In some countries, antennas exceeding a certain level of
gain may be unlawful. Refer to RF Output Power Setting in this Appendix for details on
regulatory limits.

The WEEE Directives are being implemented in each of the 28 EU and European
Economic Area (EAA) countries through national legislation. This has resulted in
considerable variation in the detailed requirements across the EU, many of which require
presence in the EU. As a result, Exalt’s WEEE compliance approach is to require the
distributors and/or resellers in the EU to comply with each country’s national legislation
by registration of the distributor or reseller as the producer and for the reseller/distributor
to carry out and fulfill the legislative requirements of each national compliance scheme.
Below is the crossed out wheelie bin symbol as required by the WEEE Directive.
EU RoHS
RoHS is the acronym used to refer to the European Union (EU) Directive 2002/95/EC on
the Restriction of the use of certain hazardous substances in electrical and electronic
equipment. Hazardous materials are those chemicals and substances that are
legislatively, market, or customer banned or restricted for use in products and/or
manufacturing. There are six (6) RoHS substances: lead (Pb), cadmium (Cd), mercury
(Hg), hexavalent chromium (Cr+6), polybrominated biphenyls (PBB) and
polybrominated diphenylethers (PBDE). Other countries may be introducing legislation
that results in similar restrictions of hazardous substances. Many Exalt products will
continue to use lead-based solder under the exemption allowed for network infrastructure
equipment. Small amounts of lead, cadmium, mercury, hexavalent chromium, PBB, and
PBDE can also be found in a few electrical and electrical components.
Europe Compliance
The EX-2.4i family operates under EN 300 328 rules as a license-exempt device. The
EX-4.9i devices are currently not permitted in any EU member or affiliate countries. The
EX-5i family operates under EN 301 893 and EN 302 502 rules as a license-exempt
device. All of these permitted devices must be professionally installed. They may only be
used as a point-to-point transmission device for fixed or temporary-fixed (non-mobile)
installations. The devices are subject to the following restrictions:
•
Do not use external amplifiers to boost the power or overcome transmission system
losses, unless the specific amplifier/cable/antenna combination has expressly been
authorized by the specific country regulations. The output power must never exceed
that specified in the Tables 1 and 2.

•
Use only parabolic dish antennas or directional flat-panel antennas. No other types of
antennas (omni-directional, yagi, and so on) are authorized. Parabolic dishes of either
grid or solid type are allowed. Maximum mid-band gain of each type of antenna
certified is:
¶ EX-2.4i models:
–
Parabolic dish: 30.3 dBi (6'/1.8m diameter)
–
Directional flat panel: 20.5 dBi (~2'/61cm square)
¶ EX-5i models:
–
Parabolic dish: 37.9 dBi (6'/1.8m diameter)
–
Directional flat panel: 28 dBi (~2'/61cm square)
