comply with the local laser safety regulations for Class 1 laser products.
Always observe standard safety precautions during installation, operation and maintenance of
this product. Only qualified and authorized service personnel should carry out adjustment,
maintenance or repairs to this product. No installation, adjustment, maintenance or repairs
should be performed by either the operator or the user.
Handling Energized Products
General Safety Practices
Do not touch or tamper with the power supply when the power cord is connected. Line voltages
may be present inside certain products even when the power switch (if installed) is in the OFF
position or a fuse is blown. For DC-powered products, although the voltages levels are usually
not hazardous, energy hazards may still exist.
Before working on equipment connected to power lines or telecommunication lines, remove
jewelry or any other metallic object that may come into contact with energized parts.
Unless otherwise specified, all products are intended to be grounded during normal use.
Grounding is provided by connecting the mains plug to a wall socket with a protective ground
terminal. If a ground lug is provided on the product, it should be connected to the protective
ground at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment
should be mounted only in grounded racks and cabinets.
Always make the ground connection first and disconnect it last. Do not connect
telecommunication cables to ungrounded equipment. Make sure that all other cables are
disconnected before disconnecting the ground.
Some products may have panels secured by thumbscrews with a slotted head. These panels may
cover hazardous circuits or parts, such as power supplies. These thumbscrews should therefore
always be tightened securely with a screwdriver after both initial installation and subsequent
access to the panels.
Connecting AC Mains
Make sure that the electrical installation complies with local codes.
Always connect the AC plug to a wall socket with a protective ground.
The maximum permissible current capability of the branch distribution circuit that supplies power
to the product is 16A (20A for USA and Canada). The circuit breaker in the building installation
should have high breaking capacity and must operate at short-circuit current exceeding 35A (40A
for USA and Canada).
Always connect the power cord first to the equipment and then to the wall socket. If a power
switch is provided in the equipment, set it to the OFF position. If the power cord cannot be
readily disconnected in case of emergency, make sure that a readily accessible circuit breaker or
emergency switch is installed in the building installation.
In cases when the power distribution system is IT type, the switch must disconnect both poles
simultaneously.
Connecting DC Power
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference
to the ground. Any single pole can be externally grounded.
Due to the high current capability of DC power systems, care should be taken when connecting
the DC supply to avoid short-circuits and fire hazards.
Make sure that the DC power supply is electrically isolated from any AC source and that the
installation complies with the local codes.
The maximum permissible current capability of the branch distribution circuit that supplies power
to the product is 16A (20A for USA and Canada). The circuit breaker in the building installation
should have high breaking capacity and must operate at short-circuit current exceeding 35A (40A
for USA and Canada).
Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate
the circuit breaker of the panel board that services the equipment and switch it to the OFF
position. When connecting the DC supply wires, first connect the ground wire to the
corresponding terminal, then the positive pole and last the negative pole. Switch the circuit
breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved should be incorporated
in the building installation.
If the DC power supply is floating, the switch must disconnect both poles simultaneously.
Connecting Data and Telecommunications Cables
Data and telecommunication interfaces are classified according to their safety status.
The following table lists the status of several standard interfaces. If the status of a given port
differs from the standard one, a notice will be given in the manual.

ringing voltages), on which overvoltages from
telecommunication networks are possible.
Safety Extra Low Voltage:
Ports which do not present a safety hazard. Usually
up to 30 VAC or 60 VDC.
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance
of a qualified safety engineer.
Always make sure that the equipment is grounded before connecting telecommunication cables.
Do not disconnect the ground connection before disconnecting all telecommunications cables.
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.
Extra caution should be exercised during thunderstorms.
When using shielded or coaxial cables, verify that there is a good ground connection at both
ends. The grounding and bonding of the ground connections should comply with the local codes.
The telecommunication wiring in the building may be damaged or present a fire hazard in case of
contact between exposed external wires and the AC power lines. In order to reduce the risk,
there are restrictions on the diameter of wires in the telecom cables, between the equipment
and the mating connectors.
Caution
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line
cords.
Attention
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de
télécommunications 26 AWG ou de section supérieure.
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In
such cases, a notice will be given in the installation instructions.
Do not attempt to tamper with any carrier-provided equipment or connection hardware.
Electromagnetic Compatibility (EMC)
The equipment is designed and approved to comply with the electromagnetic regulations of
major regulatory bodies. The following instructions may enhance the performance of the
equipment and will provide better protection against excessive emission and better immunity
against disturbances.
A good ground connection is essential. When installing the equipment in a rack, make sure to
remove all traces of paint from the mounting points. Use suitable lock-washers and torque. If an
external grounding lug is provided, connect it to the ground bus using braided wire as short as
possible.
The equipment is designed to comply with EMC requirements when connecting it with unshielded
twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially
for high-rate data. In some cases, when unshielded wires are used, ferrite cores should be
installed on certain cables. In such cases, special instructions are provided in the manual.
Disconnect all wires which are not in permanent use, such as cables used for one-time
configuration.
The compliance of the equipment with the regulations for conducted emission on the data lines
is dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal
conversion loss (LCL).
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary
protection against surges on the data lines. Primary protectors should be provided in the building
installation.
The equipment is designed to provide adequate protection against electro-static discharge (ESD).
However, it is good working practice to use caution when connecting cables terminated with
plastic connectors (without a grounded metal hood, such as flat cables) to sensitive data lines.
Before connecting such cables, discharge yourself by touching ground or wear an ESD preventive
wrist strap.

4. Ensure normal operation of the IDUs by the LED indications on the front
panel.
5. Provided that site A detects the signal from site B, the ODU starts beeping
20 seconds after power up, and continues beeping until the ODUs are
aligned, and the installation is complete.
6. In the following steps, “antenna” refers both to an external antenna and an
integrated antenna.
7. Direct the antenna of site B in the direction of site A. This is simplified if a
previous site survey has been completed and azimuths are known.
Warning
When aligning the antennas, do not stand in front of a live antenna.
8. Make a horizontal sweep of 180 degrees with the site A antenna so that the
strongest signal from site B can be detected.
9. Slowly turn the site A antenna back towards the position of site B, listening
to the tone until the best signal is reached. See the following figure for
audible signal variations.

Features
Wireless Link
Airmux-400 delivers up to 50 Mbps air rate for Ethernet and E1/T1 traffic. The
system supports a variety of spectrum bands.
Using the following technologies, the Airmux-400 air interface is designed to
ensure nonstop, high quality transmission, even under interference and harsh
conditions
•
Automatic Adaptive Rate (AAR) is a mechanism that dynamically adapts the
air interface rate by changing both the signal modulation and coding.
•
Automatic Channel Selection (ACS) chooses the best channel by monitoring
the available radio channels and dynamically selecting a channel which is best
suited for transmission at any given time.
•
Automatic Repeat Request (ARQ) is a mechanism for error control during data
transmission. When the receiver detects an error in the received information,
it automatically requests the transmitter to resend the information. This
process is repeated until the transmission is error free or the error continues
beyond a predetermined number of maximum transmissions. Airmux-400 ARQ
mechanism is optimized for time-critical traffic.
•
Forward Error Correction (FEC) with very low overhead and algorithms
specifically designed for the varying conditions of license-exempt frequency
bands, ensuring fast, robust and error-free communications.
LAN Interface
Airmux-400 includes two 10/100BaseT ports and one SFP-based Fast Ethernet
port with autonegotiation and transparent VLAN support. Traffic handling is
provided by a MAC-level self-learning bridge.
Physical Configurations
Airmux multiplexers consist of an outdoor unit (ODU), an optional external
antenna and an indoor unit (IDU) with redundant DC power supplies. The outdoor
unit is suitable for mast or wall installation.

Chapter 1 Introduction
Superior Spectral Efficiency
Built on advanced MIMO and OFDM technologies, the Airmux-400 system provides
a high-capacity link at channel bandwidth of 20 MHz. This channel bandwidth
supports high robustness of the air interface under interference and harsh
conditions. In countries where applicable, narrow channel bandwidth reduces the
cost of the spectrum license.
Security
Data transmitted over the air interface is encrypted using Advanced Encryption
System (AES) with a 128-bit encryption key.
Adaptive Modulation
Airmux-400 adaptively changes the modulation according to air conditions,
targeting maximum rate while maintaining link stability. The rate drops
temporarily after encountering interference, then automatically returns to the
highest possible rate.
Quality of Service
When the link quality is out of limits, Airmux-400 automatically searches for a
clear channel within a pre-selected list of frequencies.
Short Time-to-Service
Because Airmux-400 operates in license-exempt frequencies, it can be deployed
in record time, eliminating the costs and delays involved in leasing lines or
trenching fiber.
Monitored Hot Standby (MHS)
The Monitored Hot Standby (MHS) protects up to sixteen E1/T1 services with
Airmux-400 and up to four E1/T1 services with AirMux-200. It is designed to
provide high reliability high-capacity Point-to-Point Links. The MHS is:
•
Designed to provide redundancy and high reliability for carrier class operators
•
Optimized for high capacity links operating in license-free bands
•
A comprehensive solution providing protection against both equipment failure
and loss of air interface, by simple connectivity between a primary link and a
secondary link
•
Able to use a different band for maximum protection to the air interface
The main features of the MHS are:
•
Fully automatic switchover from the primary to the secondary link in less than
than 50 ms
•
Automatic restoration to primary link as soon as it becomes available
•
Using Airmux-200 as a backup to Airmux-400 link.
A major benefit of the MHS is that is can underpin an affordable Service Level
Agreement structure by protecting part of the Airmux-400 trunks with Airmux-200.
MHS supports TDM services; Ethernet services are carried by both links
independently.

Hub Site Synchronization
When several Airmux-400 or Airmux-200 units are collocated at a common hub
site interference may occur from one unit to another. The ODU units are supplied
with special hardware for the collocation of up to eight units.
Using a method called Hub Site Synchronization (HSS) an external cable is
connected to all collocated Airmux-400 or Airmux-200 ODUs, this cable carries
pulses sent to each ODU, which synchronize their transmission with each other.
Diversity
Airmux-400 links using dual bipolar antennas may be configured to transmit the
same data through both radios. This feature provides added data transmission
inegrity under harsh conditions.
Management
A single SNMP-based network management application (Airmux Manager) is used
to control multiple Airmux-400 and Airmux-200 links as a unified network.
VLAN management allows the separation of user traffic from NMS traffic. The
user decides if such a separation is required. Both the headquarters and remote
sites are configured with VLAN management.
Factory settings can be restored at any time for each ODU.
Information on links and management can be collected and analyzed via a single
action.
Spectrum View displays a visual representation of spectrum avail-ability during
the link installation. It is an RF survey tool supporting the link installation prior to
service activation. Use Spectrum View to choose the operating channel.

Surveying the Site
This section explains how to survey the site intended for Airmux-400 installation.
Planning the Link Site
Link site planning consists of a set of surveys, which must be carried out before
any equipment is brought to the site. If for some reason, the outcome of any of
these surveys is negative, site re-location will need to be considered.
A site survey consists of three stages:
•
2-6
Preliminary survey – The proposed link is analyzed in the office using a
topographic map.
Surveying the Site
Airmux-400 Ver. 2.3
Installation and Operation Manual
Chapter 2 Installation and Setup
•
Physical survey – The locations of the Airmux-400 indoor and outdoor
equipment are determined on-site.
•
Radio Frequency (RF) survey – It is recommended that the installation area be
scanned with a spectrum analyzer, to identify RF interference so as to
determine a clear channel for Airmux-400 installation (on-site).
Site Survey
Airmux-400 wireless links must be planned before installation. The designated
installation site must be appraised to determine that the wireless system is able
to operate efficiently and provide connectivity without signal degradation.
Airmux-400 offers a wide operating frequency range. A free frequency channel
must be determined within the operating range, for optimum performance.
Recommended equipment:
•
•
•
Stage 1 (preliminary survey)
ƒ
Topological map of the area
ƒ
Urban map of the area
ƒ
Compass
Stage 2 (physical survey)
ƒ
100 meter tape measure
ƒ

ƒ
Binoculars
ƒ
Map
ƒ
Digital camera
ƒ
Paper, pencil, and a clipboard
ƒ

can store multiple images, for documentation purposes
ƒ
RF accessories (connectors and cables)
ƒ
Communication devices (for example, cellular phones, or a set of walkie
talkies).
Stage 1 (Preliminary Survey)
A preliminary survey is necessary before visiting potential installation sites. As
much detail as possible should be obtained about the two designated ODU
installation sites and the area between them.
³
To perform a preliminary survey:
1. Mark the two designated installation sites on a topographic map of the area.
Airmux-400 Ver. 2.3
Surveying the Site
2-7
Chapter 2 Installation and Setup
Installation and Operation Manual
2. Measure the distance between the sites; check that it is within the specified
range of Airmux-400.
3. On the urban map, check for developed areas situated between the two
installation sites. Pay attention to these areas when performing the physical
site survey; there may be tall buildings, RF towers, or transmitters, which
could cause interference to the link.
4. Check the area between the two sites for obstructions such as:
ƒ
High ground - hills or mountains
ƒ
Lakes or large bodies of water. Water has a reflection effect on RF signals
like a building. This type of reflection causes the received amplitude to be
reduced. As a rule of thumb, the presence of a large body of water
between the link sites may double the required antenna height.
5. Determine and record the compass bearings between both ODUs, relative to
north.
6. If there are obstructions between the two sites, calculate the Fresnel Zone
(see Appendix C for details).
7. If the site chosen does not meet requirements, consider alternative sites.
8. Use the Link Budget Calculator (on the CD supplied with Airmux-400 or using
the Airmux Manager) to determine the expected performance.
Stage 2 (Physical Survey)
The physical site survey reviews the environment of the proposed Airmux-400
installation location, to ensure that the link sites are suitable for the wireless
network. The results of the physical site survey should be recorded.
Note
³
It is advisable to go on a clear day, so you can more easily see any obstructions
between the two sites.
To perform a physical survey:
1. From the compass readings taken in the preliminary survey, find the azimuth
(horizontal position) that the ODU should face towards the second ODU.
2. Using binoculars, locate any obstructions such as tall trees, high buildings,
hills or mountains. Look for other RF towers between the two sites. Mark the
locations of the obstructions on the map.
3. Determine the location for the ODU (having regard for existing rooftop
installations and tower space). It should be above any obstructions,
considering the Fresnel zone (see Appendix C).
4. If you need to install the ODU on a tower, make sure that the tower is far
away from overhead electric power lines.
5. Determine a location for the indoor equipment; it should be as close as
possible to the ODU. At an existing site, there is probably an equipment room
with cable-routing channels.
Note
2-8
The IDU–ODU cable length limit is 100m, in accordance with IEEE 10/100BaseT
requirements.
Surveying the Site
Airmux-400 Ver. 2.3
Installation and Operation Manual
Chapter 2 Installation and Setup
6. Measure and record the path length of the cable from the ODU position to
the indoor equipment room.
7. Determine the ground and lightning connection points of the installation. The
AirMux-400 ODU and IDU must both be grounded.
8. Using the ohmmeter, measure and record the resistance of the required
installation to the grounding point. The resistance must be less than 1O ohm.
9. Review the results of the physical site survey. Decide if the site is suitable for
the AirMux-400 wireless network installation.
ƒ
If the site is suitable, continue with stage 3, the RF survey
ƒ
If the site is not suitable, survey another site.
Stage 3 (RF Survey)
The RF survey examines the wireless environment of the Airmux-400 installation
site, to determine whether there are available channels within the Airmux-400
operating frequency band. An RF survey is performed using a spectrum analyzer.
It is advisable to familiarize yourself with the spectrum analyzer before going out
on site, specifically the Max Hold and Marker functions.
You should perform the RF survey at both proposed link sites.
The survey should be carried out during a busy time of day, to best judge the
worst-case radio interference. Allow 2–4 hours duration for a good RF survey.
Note
It is possible to install the Airmux-400 link and use the Airmux Manager to find a
clear channel. Each frequency channel can be evaluated in turn. Achievement of a
clear channel is indicated by the Quality bar on the Channel Setting window
becoming green.
2.7
Outdoor Installation
Mounting the ODU
The ODU can be mounted on a pole or a wall. In both installations, the supplied
mounting kit is used to secure the ODU.
Note
A mast-sited ODU typically uses a pole attached to the mast.
An Airmux-400 link operates in pairs of two ODUs with the same configuration.
Both ODUs must be installed, and the antennas aligned for maximum throughput.

installation time, alignment of an Airmux-400 system should be performed by two
teams simultaneously, at site A and at site B.
³
To align ODUs with integrated antennas or external bipolar antennas:
1. For external bipolar antennas: Using a coax cable with N-Type connectors,
connect the vertical polarization connector of the antenna to the ANT 1
connector of the ODU.
2. For external bipolar antennas: Using a coax cable with N-Type connectors,
connect the horizontal polarization connector of the antenna to the ANT 2
connector of the ODU.
3. Ensure that power is connected to the IDUs at both sites.
4. Ensure normal operation of the IDUs by the LED indications on the front
panel.
5. Provided that site A detects the signal from site B, the ODU starts beeping 20
seconds after power up, and continues beeping until the ODUs are aligned,
and the installation is complete.
6. In the following steps, “antenna” refers both to an external antenna and an
integrated antenna.

The procedure required to make the link functional has three phases:
1. Link Installation – detailed below.
Installation actually gets the link operational by setting the link parameters. It
uses a fixed channel at the lowest possible modulation, BPSK at 6.5Mbps and
works under the harsh interference condition.
Note
During the installation procedure, the definition of all parameters is automatically
applied to both sides of the link.
2. Link Configuration (see Chapter 4)
Configuration provides much the same functionality as Installation, but for a
running link. A fallback to Installation mode is provided for situations which
cannot be handled without resetting the link, such as antenna realignment
and IDU or ODU replacement.
The Link Installation and Configuration phases are both carried out with
Wizards, which “walk you through” the processes. The Wizards are visually
quite similar and will be described in detail below.
3.
Site Configuration (see Chapter 4)
Site specific configuration for each side of the link is available at any time under a running link or under the restricted Installation mode.

Configuring Transmit Power and Antenna Settings
The choice of Tx power, antenna gain and cable loss determines the EIRP and is
affected by such considerations as radio limitations and regulatory restrictions.
Before proceeding to antenna installation details, the following background
information should be considered:
Each Airmux-400 ODU is made of two radio transceivers (radios). The radios
make use of algorithms that utilize both polarization and space diversity resulting
in enhanced capacity, range and link availability. The number of antennas (i.e.
radios) used is determined by user configuration and by automatic system
decisions, explained below.
Dual Antennas at Both Sites
When using dual antennas at both sites (single bipolar antenna or two monopolar
antennas) you can choose between MIMO Mode and Diversity mode.
MIMO Mode
With MIMO the system doubles the link capacity. At the same time, it keeps the
same rate and modulation per radio as was used with single antenna, thus
increasing capacity, range and availability.
For example with a dual antenna Airmux-400 can transmit at modulation of
64 QAM and FEC of 5/6 and get an air rate of 130 Mbps, compared to 65 Mbps
with single antenna.
To work in this mode, each antenna port must be connected to an antenna, the
RSS level in both receivers should be balanced and a minimal separation between
the antennas must be maintained. (For example, by using dual polarization
antennas a cross polarization separation is attained).
Upon selecting Antenna Type as Dual, Airmux-400 automatically selects MIMO
mode and doubles the air rates.
AirMux Manager indicates a case of unbalanced RSS between the two antennas.
Diversity Mode
Diversity Mode uses two antennas to improve the quality and reliability of the
link. Often, there is not a clear line-of-sight (LOS) between transmitter and
receiver. Instead the signal is reflected along multiple paths before finally being
received.
Each such “bounce” can introduce phase shifts, time delays, attenuations, and
even distortions that can destructively interfere with one another at the aperture
of the receiving antenna. Antenna diversity is especially effective at mitigating
these multipath situations.
This is because multiple antennas afford a receiver several recordings of the
same signal. Each antenna will be exposed to a different interference
environment. Thus, if one antenna is undergoing a deep fade, it is likely that
another has a sufficient signal. Collectively such a system can provide a robust
link.
Antenna diversity requires antenna separation which is possible by using a
dual-polarization antenna or by two spatially separated antennas.
2-34
Working with the Airmux Manager Application
Airmux-400 Ver. 2.3
Installation and Operation Manual
Chapter 2 Installation and Setup
Use Diversity instead of MIMO in the following situations:
•
When the system cannot operate in MIMO mode
•
When one of the receivers has high interference compared to the second
receiver (i.e. the system is “unbalanced”)
•
When you achieve higher capacity in Diversity mode than in MIMO mode
•
When high robustness is of importance and the capacity of Diversity mode is
sufficient (up to 25 Mbps full duplex).
Single Antennas at Both Sites
By selecting a single antenna at both sites the ODUs operate with a single radio
that is connected to the ANT 1 connector. The second radio is automatically shut
down.
Single and Dual Antennas
In this mode one of the sites uses the ODU with a single antenna while the other
site uses the ODU with a dual antenna.
The advantages in this mode in comparison to using a single antenna in both
sites are doubled total Tx power and additional polarization and/or space
diversity.
Airmux-400 automatically switches to this mode if one of the ODUs is connected
to a dual antenna or if the RSS at one of the ODU receivers is below minimal
level.
The air rates used in this mode are same as when using single antennas in both
sites.

Considerations for Changing Antenna Parameters
Let:
•
maxAvailableTx Power denote the maximum Tx Power practically available
from an ODU (Required Tx Power per Radio in Figure 2-31) denote the
maximum Tx Power practically available from an ODU.
•
maxRegEIRP (Max EIRP in Figure 2-31) denote the maximum EIRP available by
regulation. It is determined by three factors:
ƒ
•
per band/regulation
ƒ
per channel bandwidth
ƒ
antenna gain
maxRegTxPower denote the maximum regulatory Tx Power for the equipment,
also having regard the above three points.
Then, the following relationship must be satisfied:
maxAllowedTxPower ≤ min(maxRegEIRP
– AntennaGain + CableLoss, maxRegTxPower)
³
(*)
To set Tx power and configure antennas:
1. Click the Configure buttons in turn to configure the antennas on both sides
of the link. Each one offers a dialog like this:

2. Choose the antenna type and required transmission (Tx) power for the first
site and click OK. Repeat the process for the second site.
The Tx power (per radio) indicates the power of each radio inside the ODU
and is used for Link Budget Calculations. The Tx power (System) shows the
total transmission power of the ODU and is used to calculate the EIRP
according to regulations.
Note
To see the relationship between Tx Power (radio) and TX Power (system), note
that
dBm = 10 × log 10m illiWatt
so that if you double the power in milliWatts
(for two radios) then dBm will increase by
10 × log 102 ≈ 3
.
3. Set the Antenna Gain and Cable Loss. If do this you will receive a warning
message:

• The Max EIRP level will be automatically set according to the selected band and
regulation.
• The EIRP level is the sum of the System Tx power and the Antenna Gain minus
the Cable Loss.
If inequality (*) above is violated, then the following warning window is
displayed:
Figure 2-33. Tx Power Limits
The precise relationship between the items in inequality (*) and the window of
Figure 2-31 is follows:
•
Required Tx Power (per radio) will be adjusted down to the lesser of the value
entered and maxAllowedTxPower
•
TxPower (system)is maxAllowedTxPower + 3 (for 2 radios)
•
Max EIRP is maxRegEIRP.
•
EIRP is maxAllowedTx Power + Antenna Gain - Cable Loss
The table in Figure 2-33 only shows rates where the maximum Tx Power is the
limitation, rather than regulations. When you close the window of Figure 2-33,
the change you requested will not be honored, and you will need to try again.

Configuration and Management Alternatives
The Airmux-400 configuration and monitoring operations are performed using
one of the following tools:
•
GUI-based management utility
•
Telnet.
Most of the Airmux-400 management and operation parameters are set using link
configuration wizard. If necessary, the local and remote unit parameters can be
reconfigured via the Airmux-400 management utility.
Telnet management is performed from a Telnet host using display and set
commands.
The capabilities of the two options listed above are identical.
Working with the Airmux-400 Management Utility
Before starting a management session, make sure that a communication link
between local and remote units exists. The Link Status indication bar in the
middle of the Main menu must be green and the Radio Link - Sync message must
appear in the event log (see Figure 3-3).

Figure 4-13: Configuring VLAN Settings
When this parameter is changed, it causes the management application to
immediately disconnect. In order to avoid problems, verify the change by setting
the VLAN on only one ODU. Only after proper VLAN network operation is verified,
the other VLAN setting can be changed.
Warning
³
To troubleshoot VLAN problems:
If the VLAN ID is forgotten or no VLAN network is connected to the ODU:
•
Reset the device.
In the first two minutes, neither the VLAN or any VLAN connections are
available. You may use this period to reconfigure the VLAN ID and priority.
Configuring SNMP Communities
The ODU communicates with the management application using SNMPv1
protocol. The protocol defines three types of communities:
•
Read-Only for retrieving information from the ODU
•
Read-Write to configure and control the ODU
•
Trap used by the ODU to issue traps.
The community string must be entered at login. The user must know the
password and the correct community string in order to gain access to the system.
A user may have read-only privileges.
It is not possible to manage the ODU if the read-write or the read community
values are forgotten. An alternative community key may be obtained from
technical support for the purpose of setting new community; the MAC address of
the ODU must be supplied.

Setting the Date and Time
The ODU maintains a date and time value. The date and time value can be
synchronized with any Network Time Protocol (NTP) version 3 compatible server.
(Windows XP is configured by default as a server).
On power-up the ODU configures the initial date and time using an NTP server. If
the server IP is not configured or is not reachable, a default time is set.
When configuring the NTP server IP, you should also configure the offset from
the Universal Coordinated Time (UTC). If there is no server available, you can
either set the date and time, or you can set the manager workstation time. Note
that manual setting is not recommended since reset, power up, or
synchronization with an NTP server will override the setting.
Note
• The NTP uses UDP port 123. If a firewall is configured between the ODU and
the NTP server this port must be opened.
(Windows XP command w32tm /stripchart /computer:<server IP> can be used
to check the NTP server connectivity).
• It can take up to 8 minutes for the NTP to synchronize the ODU date and time.

Locking the Link
Link Lock is a part of the security concept intended to meet a form of abuse
encountered in the field. It is designed to prevent the situation where a remote
ODU can be stolen and used as a “pirate” link to steal services or information.
The Link Lock feature actually locks the local ODU to be synchronized ONLY to
specific remote ODU. It is a site-oriented feature.
The lock can only be set from a live link. It is based on MAC authentication and is
site-oriented and activated on a per ODU basis. For example, if you lock the Site

Monitoring Performance
Airmux-400 constantly monitors traffic over the radio link and collects the
following statistics data:
•
Site 1/Site 2 received traffic rate (in Mbps)
•
Site 1/Site 2 received frames rate (in Mbps)
•
Radio signal strength (in dBm)
•
Error (blocks).
The statistics (monitor) log and event log can be saved as TXT files. New alarms
are automatically added to the text file, as they enter the event log.
Viewing Performance Reports
The Performance Monitor Report displays performance views of each of the
interfaces (see Figure 5-1) (Ethernet performance is not collected in PoE
systems.) Several performance data are collected for each of the interfaces (ES,
SES, and UAS), as well as Specific data per Interface type (e.g., TX and RX bytes
for Ethernet). For the Air Interface, user defined thresholds data are collected.
Refer to Table 5-1 and Table 5-2.
Airmux-400 Ver. 2.3
Monitoring Performance
5-1
Chapter 5 Monitoring and Diagnostics
Installation and Operation Manual
Data is collected and selectively displayed based on three time intervals as
selected by the Interval radio buttons:
•
Current (t=0)
•
15 minutes Intervals
•
Daily.
UAS – This parameter counts the time the air link was not providing any service.
There are several possible reasons for this situation; one of the sites has a power
failure, high interference, maintenance operation, etc.
Radio BBER Threshold – This parameter counts the seconds in which the radio
performance is below a user specified threshold. The threshold is measured in
percent. The threshold can be set from 0.1% up to 50%.
For links with Ethernet only service, 8% threshold is recommended and not 1%
meaning that for 8% threshold, the recommended BBER value should be 0 if
there are no problems during the 15 min interval. Since Airmux-400 provides a
loss less Ethernet service, there is throughput degradation in case of
interference. The degradation is proportional to the BBER.
The Radio RSS Threshold can also be used to indicate problems in the radio
channel. The expected RSS can be verified by means of the Link Budget
Calculator. A value of -5dB from the current RSS is recommended as a threshold.

detailed description of LEDs and their functions, refer to Chapter 3.
Alarms and Traps
Airmux-400 reports compatibility problems, fault conditions of the radio or user
links by storing events in the event log and sending traps to the NMS. For the
detailed description of the events and instructions on how to use the event log,
see Handling Events below.
Statistic Counters
The air and service interface performance data is continuously collected during
equipment operation. The collected data enables the system administrator to
monitor the transmission performance, and thus the quality of service provided
to users, for statistical purposes. For detailed description of the statistic counter,
see Monitoring Performance above.
Link Compatibility Information
Airmux-400 indicates the version compatibility via software traps. As new
hardware is added to existing networks compatibility issues may arise. An
incompatibility issue is indicated to the user via a change of color of the Link
Status box on the Main Menu screen. Trap messages in the Event Log indicate the
problems or limitations and suggest upgrades when appropriate.
The following Link Status messages are given:
fullCompatibility - different software versions that are fully compatible. Message
indicates that upgrade is available.
restrictedCompatibility - different software versions that operate correctly.
However, new features are not supported
softwareUpgradeRequired - different software versions with limited operation.
The link will operate as Ethernet only; a full service will not be available. The
message is software upgrade required.

Remote Power Fail Indication
Remote power fail indication indicates to one side that the other side has had a
power failure. The failed site sends a final trap indication about the power loss
just before powering off.
A Dying-Gasp circuit identifies the power failure at a minimum interval of
20 milliseconds before the IDU crash, during that interval a message notifying the
power failure is sent to the remote end.
Alarm output (dry contacts) indicates link loss due to power failure at the remote
end.
5.3
Handling Events
Airmux-400 detects compatibility problems, fault conditions of the radio or user
links, and initiates alarms to alert the user.
Note

Replacing an ODU
Prior to any action verify that both ODUs have the same software version
(Configuration > Configure site > Inventory). If one ODU has an old software
version, perform a software upgrade. It is important to configure the new ODU
exactly the same as the old ODU to avoid configuration mismatches, which will
disrupt the link.
An ODU may be replaced with a new ODU in one several ways.
•
Use the backup
If a backup of the configuration is available, restore that configuration using
Configuration > Configure site > Restore.
•
Manual Configuration
The new ODU can be configured manually according to the link configuration,
remember to use the same settings for SSID, channels, link password, IP
addresses, and names.
•
Restore Factory Setup
From version 1.6xx the feature of Restore Factory Setup is available. Using
this feature we recommend putting the remaining ODU back to factory setup
Configuration>Configure site>Advance option, and then activate the second
ODU reconfiguring the link from scratch.
Option number 3 is a recommended option to prevent configuration mismatches.

Frequently Asked Questions
Q: What performance issues will arise due to environmental conditions?
A: Airmux-400 is not sensitive to environmental conditions. However if heavy rain
or snowfall is expected ensure the performance by allowing a higher fade margin
in the link budget planning calculations.
Q: When using the Airmux-400, what is the potential for interference between
our system and other cellular or wireless network devices?
A: The Airmux-400 is a robust system. However since it operates in unlicensed
band there maybe some interference. Nevertheless, the fact that we can
manually set the frequency gives us the flexibility to find a clear channel. In
addition each Airmux-400 link uses unique user configurable SSID code.
Q: What type of security is offered on Airmux-400?
A: Airmux-400 has three levels of security:
1. AES hardware mechanism
5-20
Frequently Asked Questions
Airmux-400 Ver. 2.3
Installation and Operation Manual
Chapter 5 Monitoring and Diagnostics
2. Each unit uses a unique SSID link-specific code (up to 24 alphanumeric
characters)
3. Proprietary protocol protects from eavesdropping from other systems.
Q: Can we use horizontal and vertical polarization on the same frequency to
double the number of wireless links?
A: Installing two Airmux-400 systems in the same band with cross polarization
provides 20–25 dB separations. Nevertheless, since there are reflections, the
cross polarization separation is decreased and spatial separation is
recommended.
Q: Could you add the frequency of 5.735 to the manual selection in order to
increase the number of 20 MHz channels to six?
A: Currently the system provides fixed channels, with one manual frequency
setting. The manual setting provides flexibility of spectrum selection, including
5.735 MHz.
Q: Can we manage Airmux-400 using SNMPc other than the supplied
management software that comes with the units?
A: Yes. The Airmux-400 is SNMP-based. Airmux-400 can be managed when using
other SNMP software after implementing RAD MIBs.
Q: Can Airmux-400 be managed and configured via Telnet?
A: Yes.
Q: Can I use Airmux-400 with any vendor’s external antenna?
A: Yes. RAD supplies the Airmux-400 external ODU with an N-type typical
connector. Any vendor’s external antenna that can be cascaded to our external
unit can be used without problem. Please note that dB losses in the cascading
cable between the external ODU and antenna should be taken into consideration.
(In the supplied cascading cable of one meter we have 1 dB loss)
Q: Do we need to add external arrestors on Airmux-400 cables?
A: The Airmux-400 ODU includes arrestors and lightning protection. Therefore
there is no need to add additional arrestors.
Q: What is the actual Ethernet data rate and maximum throughput?
A: The maximum net throughput of Airmux-400 is full duplex 18 Mbps.
Note
Airmux-400 is a symmetrical system
Q: What is the sensitivity for each rate of the Airmux-400?
A: The rate sensitivities are:

contains a MAC address table with up to 2047 entries.
Q: Can I use any category 5e cable in order to connect the IDU and ODU?
A: The cable should be suitable for outdoor use (shielded Category 5e).
Q: What are the BER values expected in the Airmux-400 link?
A: 10-11 (according to BER sensitivity threshold)
Q: Does Airmux-400 use DSSS technique?
A: No, Airmux-400 uses the advanced OFDM technique.

Appendix C Link Budget Calculator
For each product (or regulation and band) the calculator stores the following data
required for link budget calculations:
•
Maximum transmit power (per modulation)
•
Receiver sensitivity (per modulation) for Ethernet service and for TDM
services at various BER
•
Maximum linear input power (used to calculate minimum distance)
•
Antenna gain and cable loss for ODU with integrated antenna
•
Available channel bandwidths.
Calculations
EIRP
EIR P = TxPower + AntennaGain Site A – CableLoss SiteA
Expected RSS and Fade Margin
ExpectedRSS = EIRP – PathLoss + AntennaG ain SiteB – CableLoss Site B
where:
•
Site A is the transmitting site
•
Site B is the receiving site
•
PathLoss is calculated according to the free space model,
PathLoss = 32.45 + 20 × log 10( frequency MHz ) + 20 × log 10( RequiredRange Km )
ExpectedFadeM arg in = Sensitivity – ExpectedRSS
where Sensitivity is dependent on air-rate.
Min and Max Range
MinRange is the shortest range for which ExpectedRSS ≤ MaxInputPower
per air-rate.
MaxRange (with Adaptive checked) is the largest range for which
ExpectedRSS ≥ Sensitivity , at the highest air-rate for which this relationship
is true. In a link with adaptive rate this will be the actual behavior.
MaxRange (for a given air-rate) is the largest range for which
ExpectedRSS ≥ Sensitivity + RequiredFadeM arg in .
Service
The Ethernet throughput is calculated according to internal product algorithms.
Availability
The Service Availability calculation is based on the Vigants Barnett method which
predicts the downtime probability based on a climate factor (C factor).

About the Fresnel Zone
The Fresnel zone is an elliptically shaped conical zone of electromagnetic energy
that propagates from the transmitting antenna to the receiving antenna. It is
always widest in the middle of the path between the two antennas.
Figure C-8. Fresnel Zone
Fresnel loss is the path loss occurring from multi-path reflections from reflective
surfaces such as water, and intervening obstacles such as buildings or mountain
peaks within the Fresnel zone.
Radio links should be designed to accommodate obstructions and atmospheric
conditions, weather conditions, large bodies of water, and other reflectors and
absorbers of electromagnetic energy.
The Fresnel zone provides us with a way to calculate the amount of clearance
that a wireless wave needs from an obstacle to ensure that the obstacle does
not attenuate the signal.
There are infinitely many Fresnel zones located coaxially around the center of the
direct wave. The outer boundary of the first Fresnel zone is defined as the
combined path length of all paths, which are half wavelength (1/2 λ) of the
frequency transmitted longer than the direct path. If the total path distance is
one wavelength (1 λ) longer than the direct path, then the outer boundary is said
to be two Fresnel zones. Odd number Fresnel zones reinforce the direct wave
path signal; even number Fresnel zones cancel the direct wave path signal.
The amount of the Fresnel zone clearance is determined by the wavelength of
the signal, the path length, and the distance to the obstacle. For reliability, point-

to-point links are designed to have at least 60% of the first Fresnel zone clear to
avoid significant attenuation.
The concept of the Fresnel zone is shown in Figure C-8 above. The top of the
obstruction does not extend far into the Fresnel zone, leaving 60% of the Fresnel
zone clear; therefore, the signal is not significantly attenuated.

Lightning Protection and
Grounding Guidelines
This appendix describes how to achieve best protection against electric shock and
lightning.
100% protection is neither implied nor possible.
Warning
Note
This appendix is at best a guide. The actual degree of lightning protection
required depends on local conditions and regulations.
D.1
Protection Elements
Lightning protection system consists of the following components:
•
Grounding for the antenna coax cable
•
Grounding for each IDU and ODU
•
External primary surge suppressor units and grounding for the outdoor cable
•
Internal ESD protection circuits over the power/telecom lines.
D.2
Grounding for Antenna Cable
A grounding kit must be connected to the coax antenna cable and reliably
grounded as shown in Figure D-1. The grounding kit is an Andrew Type 223158-2
(www.andrew.com).

Grounding for Outdoor/Indoor Units
ODU and IDU of the Airmux-400 system must be grounded.
ODU Grounding
Airmux-400uses a shielded CAT-5e cable to interconnect the outdoor (ODU) and
indoor (IDU) units. However, this shielding does not provide a good lightning
discharge path, since it cannot tolerate the high lightning current surges.
To provide an alternate lightning discharge path, the ODU and antenna grounding
posts should be connected to ground point by a 10 AWG short copper wire. The
device must be permanently connected to ground.
IDU Grounding
The IDUs grounding post should be connected to the internal ground point, using
a grounding wire of at least 10 AWG. The grounding wire should be connected to
a grounding rod or the building grounding system. The device must be
permanently connected to ground.

The Transtector protection circuits shown in Figure D-5 below, utilize silicon
avalanche diode technology. The unit consists of an outdoor-rated NEMA 3R type
enclosure with easy mounting flanges, ground stud attachment and easy wiring.
The ALPU-POE features RJ-45 protection circuits for the ODU-IDU data pairs (pins
1, 2 and 3, 6) and DC power (pins 4, 5 and 6, 7 with the pairs bonded).
The unit is designed to be wall-mounted. An optional set of bracket is available to
allow a wide range of pole mount applications. A dedicated ground stud is
provided inside the unit that must be bonded to the nearest grounding system
(or master ground bar) for proper surge protection.
The system wiring is installed with RJ-45 type connectors that can feed directly
into the chassis without having to cut, splice or route through awkward strain
relief holes.
Figure D-5. Surge Suppressor
³
To mount the lightning protection devices:
1. Mount the device as close to the ODU as possible. Mount the unit so that the
cable connectors are at the bottom (to prevent water from penetrating), with
the strain reliefs facing the ground.
2. Remove the cover by unscrewing the front of the unit.
3. Mount the unit to an outside surface using the two mounting holes.
4. Connect the ODU-IDU cable using the RJ-45 jack.
5. Connect one cable between the ODU and the suppressor using an RJ-45 jack.
6. Connect the suppressor’s ground stud to a grounding point. Use the
appropriate wire gauge and type, keeping the wire as short as possible, less
than 1m (3 feet), between the stud and the site grounding point.
7. Replace the cover.
Note
Airmux-400 Ver. 2.3
There may also be regulatory requirements to cross bond the ODU-IDU CAT-5e
cable at regular intervals up the mast. This may be as frequent as every
10 meters (33 feet).

Appendix E
MIB Reference
The RAD MIB is a set of APIs that enables external applications to control RAD
equipment.
The MIB is divided into public and a private API groups:
•
Public: RFC-1213 (MIB II) variables, RFC-1214 (MIB II) System and
Interfaces sections
•
Private: Controlled by RAD and supplements the public group.
This appendix describes the public and private MIB used by RAD.
The following terms are used in this appendix.
•
MIB – Management Information Base
•
API – Application Programming Interface
•
SNMP – Simple Network Management Protocol.
E.1
Interface API
The Airmux Manager application provides all the means to configure and monitor
an Airmux-400 link, communicating with the SNMP agent in each ODU. Each SNMP
agent contains data on each of the IDUs and ODUs in the link. Both agents
communicate with each other over the air using a proprietary protocol.
Note
Each ODU has a single MAC address and a single IP address.
To control and configure the device using the MIB, you should adhere to the
following rules:
Airmux-400 Ver. 2.3
•
The connection for control and configuration is to the local site, over any
SNMP/UDP/IP network.
•
All Parameters should be consistent between both of the ODUs. Note that
inconsistency of air parameters can break the air connection. To correct air
parameters inconsistency you must reconfigure each of the ODUs.
•
Common practice is to configure the remote site first and then to configure
the local site.
•
For some of the configuration parameters additional action must be taken
before the new value is loaded. Please refer to the operation in the
parameters description.
Interface API
E-1
Appendix E MIB Reference
•
Installation and Operation Manual
Some of the MIB parameters values are product dependent. It is strongly
recommend using the AirMux Manager Application for changing these values.
Setting wrong values may cause indeterminate results.
To control a link, all SNMP requests should go to the local site IP address.
The AirMux Manager uses the Read Community strings public for the local ODU
and public-remote for the remote ODU. It uses Write Community strings netman
for the local ODU and netman-remote for the remote ODU. These are the actory
defaults.
E.2
Private MIB Structure
The sections in the private RAD MIB and its location in the MIB tree are shown in
Figure E-1.
Figure E-1. Top Level Sections of the Private MIB
The products MIB section contains the definition of the Object IDs for the two
form factors of the ODU, Integrated Antenna and Connectorized (referred in the
MIB as external antenna):
The ODU MIB contains the sections: Admin, Service, Ethernet, Bridge, Air, PerfMon
and Agent.

Appendix E MIB Reference
The IDU MIB contains the sections: Admin, Service, Ethernet, Bridge and TDM.
The general MIB include a single generic parameter that is used by all traps as a
trap description parameter.
E.3
MIB Parameters
The following section describes all of the MIB parameters. The MIB parameters
follow the following naming convention:
<airmux400><Section 1>...<Section n><Parameter Name>
For each of the configuration and control parameters (parameters with readwrite access), the “Description” column describes when the new value is
effective. It is recommended that you perform the appropriate action to make
the values affective immediately after any change. Where a change is required on
both sides of the link, it is recommended that you change both sides of the link
first and then perform the action.

MIB Traps
Each ODU can be configured with up to 10 different trap destinations. When the
link is operational, each ODU sends traps originating from both Site A and Site B.
The source IP address of the trap is the sending ODU. The trap originator can be
identified by the trap Community string or by the trap description text. The public
Community string is used for Site Al ODU traps and public-remote (as set by the
user) is used for Site B ODU traps.
Each trap contains a trap description and additional relevant information such as
alarm severity, interface index, time stamp and additional parameters.

Preloading IP Address and
Changing Default Band
This appendix explains how to preload a static IP address to an ODU and change
its factory-default band in the field.
F.1
Preloading an ODU with an IP Address
All ODUs supplied by RAD come pre-configured with an IP address of 10.0.0.120.
For use in a network, the ODUs must be configured with suitable static IP
addresses. The method for doing this under office conditions is explained in
Chapter 4. This section explains how do achieve the same thing in the field.
The minimal equipment required to pre-load an ODU with an IP address is:
³
•
Laptop computer (managing computer)
•
An installed copy of the Airmux Manager
•
A PoE device
•
A crossed Ethernet LAN cable
•
An IDU-ODU cable
•
If you have connectorized ODUs, two N-type RF terminators.
To preload an ODU with an IP address:
1. Using the IDU-ODU cable, connect the PoE device to the ODU, ensuring that
the cable is plugged into the PoE port marked P-LAN-OUT.
2. For connectorized ODUs, screw the RF terminators into the two antenna
ports.
Warning
A powered up ODU emits RF radiation from the antenna port (or connected
antenna). When working with a powered up connectorized ODU, always use RF
terminators.
For an ODU with an integrated antenna, ensure that the antenna is always
directed away from people.
3. Connect the Poe device to AC power.
4. Using a crossed LAN cable, connect the LAN-IN port of the PoE device to the
Ethernet port of the managing computer. The ODU will commence beeping at
about once per second, indicating correct operation.

Hub Site Synchronization
When several units are collocated at a common hub site, interference may occur
from one unit to another. RAD ODU units support the collocation of up to
16 units at a central site.
For Airmux-400, HSS support depends on the product model.
Using a method called Hub Site Synchronization (HSS) a cable is connected from
the master ODU to all collocated ODUs; this cable carries pulses sent to each
ODU, which synchronize their transmission with each other. The pulse
synchronization ensures that transmission occurs at the same time for all
collocated units. This also results in all of the hub site units receiving data at the
same time, eliminating the possibility of interference that could result if some
units transmit while other units at the same location receive.
Figure G-1 shows interference caused by non-synchronized collocated units.
Figure G-1. Interference Caused by Collocated Units
The units are connected to each other with HSS cables and HSS distribution units.
One of the radios in the site is defined as HSS Master and generates synchronization pulses.
The other collocated radios in the site, the HSS clients, are connected to the HSS
master and synchronize their transmission to the pulses. An HSS client can be
configured to work in one of two modes:
•
Airmux-400 Ver. 2.3
HSS Client-Continue Transmission (HSC-CT): If the unit loses synchronization
with the HSS master, the link remains active. However, without
synchronization pulses, it is possible that this unit will cause interference.
Hardware Installation
G-1
Appendix G Hub Site Synchronization
•
Installation and Operation Manual
HSS Client-Disable Transmission (HSC-DT): If the unit loses synchronization
with the HSS master, the link is dropped until the synchronization pulses
resume. This setting prevents the unit from causing interference.
The remote ODUs that are not located at the hub site, are called independent
units and do not require HSS hardware.
Figure G-2. Collocated units using Hub Site Synchronization (A)
Figure G-3. Collocated units using Hub Site Synchronization (B)
G.1
Hardware Installation
HSS supports installation of up to sixteen collocated units. In addition to each
unit being connected to its IDU or PoE device, the collocated unit has an
additional cable that is connected to the HSS Unit. The HSS Unit is a compact,
weatherproof (IP67) connector box that is installed on the same mast as the
ODUs. All collocated units connect to this box via CAT 5e cable. Prepared lengths
are available for purchase.
The HSS unit is supplied with ten protective covers; any port not in use must be
closed with a protective cover.

Appendix G Hub Site Synchronization
Figure G-4. HSS Interconnection Unit
Note
• If you collocate more than eight radios, cascade two HSS Units with an HSS
cable.
• Ensure that the collocated units are connected in sequence from SYNC 1. If an
ODU is removed form the hub site, then all remaining ODUs must be
reconnected to maintain the connectivity.
³
To connect an ODU to the HSS
1. Prepare a Cat. 5e cable with RJ-45 connectors in accordance to the cable
ODU-to-HSS unit cable wiring in Appendix A.
2. Unscrew the protective cover from the port marked SYNC 1.
3. Connect the RJ-45 connector from one end of the CAT 5e cable to SYNC 1.
4. Connect the other end of the CAT 5e cable to the ODU connector labeled
SYNC.
5. Tighten the protective seal that is on the prepared cable over the RJ-45
connector.
6. Repeat for all ODUs that are to be collocated at the hub site. The next ODU
to be connected is inserted to SYNC 2, followed by SYNC 3 and so on.
Note

Installation and Operation Manual
Radio Frame Pattern Table
Under HSS, the TDD mechanism of the collocated radios transmits at the same
time and receives at the same time. The cycle duration of transmit and receive is
called Radio Frame Pattern (RFP) and with Airmux-400 it is always 1250
milliseconds.
Figure G-5. Radio Frame Pattern
Five RFP types (A to E) are available. The RFP is selected depending on the type
of the radio products, services and channel bandwidth used by the complete
system.
Note
• RFP type E should be used if and only if Airmux-400 links are part of the HSS
installation.
• The RFP must be the same for each link within the collocated system.
Select the RFP that gives you the Best Fit for the system services and select the
Channel Bandwidth accordingly.
The table below describes the efficiency of the Airmux-400 air interface according
to the RFP type, radio products mix, services and channel bandwidth. The table
may be viewed in the Airmux Manager and in the Link Budget Calculator and
varies according to the product used.

Airmux-400 Considerations
Airmux-400 radios use a Radio Frame Pattern of 1250 milliseconds regardless of
HSS. Hence for the Airmux-400 performance, as calculated with the Link Budget
Calculator, it is irrelevant if the radios operate in HSS mode or not.
Airmux-200 Considerations
When Airmux-200 radios are collocated with Airmux-400 radios using HSS, all
radios must use a Radio Frame Pattern (RFP) of 1250 milliseconds. The
performance of Airmux-200 radios that operate with this RFP can be seen in the
Link Budget Calculator when selecting RFP type E.
The following list summarizes the effect of 1250 milliseconds RFP on Airmux-200
radios. These effects should be considered in when planning new installations.
•
Only Channel Bandwidths 20 and 10 MHz are supported
•
For products supporting a maximum throughput of 18.1 Mbps, the maximum
Ethernet throughput is 14.5 Mbps at the 20 MHz channel and 9.3 Mbps at the
10 MHz channel
•
The 5 MHz Channel Bandwidth is supported only in Airmux-200-ACCESS
products
•
For products supporting maximum throughput of 21.4 Mbps, the maximum
Ethernet throughput is 22.5 Mbps at the 20 MHz channel and 9.3 Mbps at the
10 MHz channel.

Installing a Hot Standby
Link
The Airmux hot standby link is a duplicated link set up as a primary link and a
secondary link in hot standby mode as shown in figure below.
Figure H-1. Hot Standby Link
RAD MHS provides redundancy and backup to TDM services. It is designed to
provide high reliability high-capacity Point-to-Point links. The RAD MHS is:
•
Designed to provide redundancy and high reliability for carrier class operators
•
Optimized for high capacity links operating in license-free bands
•
A comprehensive solution providing protection against both equipment failure
and loss of air interface, by simple connectivity between a primary link and a
secondary link
The main service redundancy features of the RAD MHS are:
•
Airmux-400 Ver. 2.3

Hot Standby Package Contents
H-1
Appendix H Installing a Hot Standby Link
Installation and Operation Manual
•
TDM service cut-over time no more than 50 ms
•
Automatic restore to primary link as soon as it becomes available
•
Support for up to sixteen TDM channels for Airmux-400 and four TDM
channels for Airmux-200.
MHS is supported between:
•
Two Airmux-200 links
•
Two Airmux-400 links
•
An Airmux-200 link and an Airmux-400 link.
Equipment Protection
Equipment protection is provided for the electrically-active network elements,
ODU and IDU.
The primary IDU and the secondary IDU are connected by a cable to monitor
failure and to control protection switching. Switching time is less than 50 ms.
When connecting two Airmux-400 links as 1+1, one dual-polarization antenna can
be shared by the primary link and the secondary link.
Air-Interface Protection
Air-Interface protection is unique to RAD and is optimized for wireless links
operating in license-free bands.
The primary link and the secondary link use different frequency channels. If the
air-interface of the primary link is disturbed and cannot carry the required TDM
service, then the system automatically switches to the secondary link.
In addition, improved robustness and frequency planning flexibility is achieved, as
the primary and secondary air interfaces can operate in the same frequency band
or in different frequency bands.
Automatic Channel Selection (ACS) can be configured for each link to add
additional robustness.
The primary and secondary links are synchronized using Hub Site Synchronization
(HSS).
It is recommended that both sites be installed with HSS cables. If HSS fails at one
site, it can be operated from the other site by remote configuration.

Figure H-3. Connecting IDUs to Patch Panels
Note
• With Airmux-400 links you can protect up to 16 TDM ports. To protect more
than eight TDM ports use two patch panels at each site.
• Ethernet services are carried independently by primary and secondary links.
Each link carries different Ethernet traffic. MHS does not protect Ethernet
traffic.

In what follows, it is assumed that:
³
•
We depart from our usual Site A / Site B conventions. Sites A and B on the
primary link will be Sites 1.2 and 1.4 respectively. The corresponding sites on
the secondary link will be Sites 2.2 and 2.4. The site names reflect their IP
addresses. This is a useful convention and is reflected in the screen captures
below.
•
The link will be managed from Site 1.2; Site 1.4 may be a remote site.
•
The links intended as the primary and secondary are referred to their
respective names, Primary Link and Secondary Link as shown in Figure H-1
above, despite their having yet to be installed.
To install a hot standby link:
1. Set up Primary Link in the usual way. Ensure that it is fully operational in
accordance with the relevant instructions in the previous chapters of the
manual.
Note
Do not proceed unless this condition is fully met!
2. Connect user equipment to Site 1.4.
3. At Site 1.2, disconnect the TDM cables from the external equipment or
disconnect external equipment from the Hot Standby patch panel.
4. The HSS cable (connecting the ODUs) should be connected at Site 1.2. The
ODU belonging to the primary link should be configured as HSM, whereas the
ODU belonging to the secondary link should be configured as HSC-CT.
5. Establish Secondary Link in the usual way, with HSS enabled. The two link
frequencies should be at least 5 MHz apart.
6. Connect the MHS cables at Sites A and B as shown in Figure H-1 and
Figure H-3 above.
7. Run the Configuration Wizard for Primary Link. Activate TDM services in the
usual way. Notice that there is a new tab, "Hot Standby", in the Services
Configuration panel:

Maintaining a Hot Standby Link
IDU Replacement
There are two situations, which must be treated differently.
Situation 1
To replace either of the IDUs at Site 1.4 or the secondary IDU at Site 1.2, nothing
special is required. Simply disconnect the IDU to be replaced – and replace it with
a new one. Replacing a secondary link IDU obviously has no effect on the TDM
service. Disconnecting the Site 1.4 primary IDU activates Hot Standby. After the
Site 1.4 primary IDU is replaced, the Link will detect the change and switch back
to the primary link.
If you replaced the Site 1.2 secondary IDU, remember to reconnect the MHS
cable.

To replace the Site 1.2 primary link IDU:
1. 1. Power off the Site 1.2 primary IDU. This activates the secondary link using
Hot Standby.
2. Run the Configuration manager on the secondary link, and in the Hot Standby
panel of Figure H-5 above, check the Disabled button.
3. Replace the Site 1.2 primary IDU without connecting it to the ODU (to
prevent transmission by the primary link with the undefined IDU).
4. Reconnect the MHS cable between the IDUs at Site 1.2.
5. Again, run the configuration wizard on the secondary link, and in the panel of
Figure H-5 above, check the Secondary button to re-enable the link as
secondary.
6. Connect the new Site 1.2 primary IDU to its ODU.
The hot standby automatically reverts to the primary link within 50 ms.
ODU Replacement
Both the primary and secondary replacement ODUs require pre-configuration
prior to insertion into the link. The items to be pre-configured are
Note
³
•
HSS mode
•
Link ID
•
Frequency
•
Hot Standby mode – using the new Services panel in Figure H-5 above
•
IP address (optional).
Pre-configuration must be carried out before the new ODU is connected to its
IDU. If you try to do it "live" against its IDU, it will cause spurious transmissions
and a service break.
To pre-configure an ODU:
1. Attach the new ODU to a PoE device or IDU.
2. Run the Airmux Manager and use Hot Standby tab of Figure H-5 above to
configure the new ODU to Primary or Secondary mode as required.
3. Ensure that it is set to the proper HSS mode in accordance with Figure H-5
above. Enter the required Link ID and frequency.
³
To replace an ODU for primary or secondary link, at either site:
•
H-10
Install the pre-configured ODU. (Since the other link is working normally,
nothing need be done with it. If the secondary ODU was replaced, service
remains as is on the primary link. If the primary ODU was replaced, then the
service switches back to the primary link.)

Monitoring the Links
If the Airmux Manager is logged in to a link, you cannot run a second copy of it
simply by clicking its desktop icon. It is assumed that your running copy of the
Airmux Manager is logged into the primary link.
³
To setup an Airmux Manager desktop icon for the secondary link:
1. Using copy and paste create a copy of the Airmux Manager icon on your
desktop.
2. Right-click it to display the Properties menu. You should see something
similar to this:
Figure H-10. Airmux Manager Shortcut Properties
3. Scroll to the end of the Target field, and outside the inverted commas add a
space, followed by the IP address of Site 1.2 for the secondary link. If for
example it is 10.0.0.125, the above Target filed would look like:
"C:\Program Files\RAD\Airmux Manager\AirMuxManager.exe" 10.0.0.125
4. Click OK.
You may now use the new icon to run a second copy of the Airmux
Manager. It will run against the IP address you indicated, bypassing the
login process.

Switching Logic
This section describes logic behind link switchover and restoration process.
Switching from Primary Link to Secondary Link
Switching from primary link to secondary link will occur following:
•
Loss of the primary air interface due to sync loss
•
Loss of the primary air interface due to failure of the receiver to acquire
expected E1/T1 data during a period of 24 ms
•
The primary equipment (either ODU or IDU, local or remote) is powered off.
Following the switch from the primary to the secondary link, the primary and
secondary link Manager main windows should look like this:

After a few seconds the display in Figure H-11 moves to No-Link display, with
TDM ports grayed out.

Switching back from the Secondary to the Primary Link
Switching back from the secondary link to the primary link will occur after the
primary link has become and remains fully functional for a continuous period of
at least one second. Following reversion from the secondary link to the primary
link, the Manager main windows should look like this:

System Operation Description
Normal operation:
•
E1 services are carried by the primary link
•
The secondary link (equipment and air interface) is operating but not carrying
user traffic
•
E1 ports on the secondary IDUs are tri-state.
Switching to backup link:
•
Loss of the primary air interface due to sync loss
•
Loss of the primary air interface due to failure of the receiver to acquire
expected E1/T1 data during a period of 24 ms
•
Primary equipment power off (either ODU or IDU, local or remote)
•
E1 ports on the primary IDUs turn to tri-state
•
E1 ports on the secondary IDUs become active.
Backup operation: E1 services are carried by the secondary link
Restoration of primary link: Switching back to primary occurs as soon as the
primary link is fully functional for 1 second.

FCC/IC DFS Installation
Procedure
The FCC/IC regulation for 5.4/5.3 GHz allows unlicensed wireless data equipment,
provided that it does not interrupt radar services. If radar activity is detected, the
equipment must automatically change frequency channel. This feature is termed
Dynamic Frequency Selection (DFS). According to the standard, a channel with
active radar is prohibited from use for 30 minutes. Before using a channel for
transmission, the radio equipment must probe it for radar signals for a period of
60 seconds.
Airmux-400 products have the DFS feature available as well as ACS.
An immediate consequence of the FCC/IC regulation for 5.4/5.3 GHz is that the
standard method of link installation using a single default fixed installation
channel, cannot be used.
Instead of the installation procedure of Chapter 2, a link activation method is
used.
The ODUs are either supplied from the factory ready for use at 5.4 GHz or
5.3 GHz FCC/IC or alternatively, they can be set up for these bands using the
Airmux Manager.
Note
The following procedure is generic to all relevant RAD radio products. What you
see on your running Airmux Manager may differ in some details from the screen
captures used to illustrate this appendix.
