Chapter 2 : Planning
Introduction
This chapter is aimed at management and planning staff to enable them to assess the
requirements for installing a Velox LE digital radio link.
System Type Selection
The Velox LE 2400, Velox LE 5800, Velox LE 2410 SR, Velox LE 5810 SR, Velox LE
24 10 SRi and Velox LE 5810 SRi are ISM band digital radio systems that provide short
to medium range, point -to-point digital communication with high data security at rates
of T1, 2T1 or 4T1. Alternatively, the radio can be software configured to convey E1,
2E1 or 4E1. The radio can also be configured to bridge or route IP traffic via a 10Base-
T port. The data rates scale depending on the number of enabled T1/E1 tributaries and
whether the data is being bridged or routed. The products make use of spread sp ectrum
technology and may be operated license-free in the 2.4 GHz and 5.8 GHz ISM bands.
The Velox LE 2425 SR, Velox LE 5825 SR, Velox LE 2425 SRi, Velox LE 5825 SRi,
Velox LE 2450 IP, Velox LE 5850 IP, Velox LE 2450 IPi, Velox LE 5850 IPi, Velox
LE 2450 SR, Velox LE 5850 SR, Velox LE 2450 SRi and Velox LE 5850 SRi are
similar radios also operating in the 2.4 and 5.8 GHz ISM bands respectively.
Modulation can be switched between 16 and 32 QAM with digital output scalable up to
16 T1/E1 tributaries depending on the specific radio.
The Velox LE digital radio system is aimed at FCC regulated markets. Each radio in the
system consists of two main parts:
A Radio Frequency Unit (RFU) operating in the 2.4 GHz or 5.8 GHz ISM
frequency bands. The RFU has an N-type female connector for connection to a
range of antennas and can either be and Outdoor RFU (ORFU) or and Indoor RFU
(IRFU).
RFU units available are the Velox LE 2410, Velox LE 5810, Velox LE 2410i,
Velox LE 5810i, Velox LE 2450, Velox LE 5850, Velox LE 2450i and Velox LE
5850i units. The models with an “i” suffix are 1RU high IRFUs. See RFU Variants
on page 9-1 for further information.
A Digital Indoor Unit (DIU), available with a Telecommunications interface (0 to
16 T1/E1 tributaries depending on the radio) and a Data interface (10Base-T
Ethernet or 10/100Base-T Ethernet, depending on the radio).
DIU units available are the Velox LE 75/120 Ohm, Velox LE 120 Ohm, Velox LE
10, Velox LE 25 and Velox LE 50 un it. All DIUs operate with the Velox LE
2410/2410i and Velox LE 5810/5810i RFUs. Velox LE 10, 25 and 50 DIUs can
operate only with the Velox LE 2450, 5850, 2450i and 5850i RFUs. With the
exception of the Velox LE 75/120 Ohm and Velox LE 120 Ohm units the number
is a guide to the maximum data capacity of the unit. For example, the maximum
data capacity of the Velox LE 25 is 25 Mbps. DIU Variants on page 9-1.

Antenna Selection
General
The antenna type must be selected before the system is installed. The chosen antenna
must enable the system to operate with sufficient link fade margin without excessive
cost and allow the user’s ‘link availability requirements’ to be met. The main
consideration when selecting an antenna is antenna gain measured in dBi. A path loss
analysis is highly recommended to determine the antenna gain needed for adequate fade
margin.
Refer to the Link Planner spreadsheet (LinkPlanner.xls) on the supplied CD for
assistance with planning the link and antenna gain selection.
The Table 2-1 below shows antenna selection guidelines for some configurations. The
distances are calculated for a 20 dB link fade margin. To reduce potential radio
interference to other users, the antenna type and its gain should be chosen so that the
equivalent isotropically radiated power (EIRP) is not more than that required for
successful communication.

WARNING
WARNING: It is the responsibility of the professional installer to ensure that when
using the outdoor antenna kits in the United States (or where FCC rules apply), only
these antenna configurations shown in the table above are used. The use of any
antenna ot her than those listed is expressly forbidden in accordance to FCC rules
CFR47 part 15.204.
!
CAUTION
The Velox LE System should be installed and operated with fix-mounted antennas
that are located with a minimum separation distance of 2 meters (6.6 ft) or m ore
from all persons during normal operation to satisfy RF exposure requirements.
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment when installed as directed.
Site Evaluation
When planning a site for a digital radio link, it is important that you take the operational
environment of the proposed site into account.
Chapter 2. Planning
2-4 862-02411 February 04
The combined effect of atmospher ic environmental factors such as rain and lightning,
atmospheric attenuation, signal path obstruction, propagation fading, air temperature
gradients, ice build-up, wind and solar radiation can contribute towards reducing the level
of performance of the system. The 2.4 GHz and 5.8 GHz bands are not adversely affected
by rain, ice or snow. Severely cold and excessively warm climatic conditions outside the
scope of the operating temperature range can affect the function of the system, especially
the outdoor equipment (see Environmental Characteristics on page 8-13 of this manual).
Wind force build-up and/or vibration of the mast-mounted equipment can affect the
antenna beam alignment and Outdoor equipment reliability. Ensure that mast used is
rigid enough to withstand the wind forces expected at the install location.
Multipath Effects
The effects of multipath propagation can influence the radio. Understanding these
effects will help when installing a radio link and maximize the reliability of the link.
Multipath fading occurs when the receiving antenna receives not only the direct signal
from the transmitting antenna but also a signal from the transmitting antenna that has
reflected off the ground or nearby obstacles. The reflected signal takes a longer path to
reach the receiver and acts as interference since it is not in-phase with the direct path
signal. The amplitude of the interference can be almost equal to that of the direct path
signal, thus degrading the performance of the link.
Multipath propagation is dependent on transmit frequency and the specific geometry of
the link such as antenna heights, distance between the antennas and the local terrain. To
counteract multipath propagation, the installer can change the frequency at which the
link operates or adjust the height of one or both of the antennas.

Interference Considerations
Other devices that can cause interference to the Velox LE radio systems use the ISM
frequency bands. Interference can be avoided by careful planning of the system
installation. The available methods for providing isolation from interfering radiators
are the following:
Frequency diversity
Antenna polarization
It is recommended to scan the proposed installation areas with a spectrum analyzer prior
to installation to establish the presence of interference. The spectrum analyser feature
available on the NCT/GUI may also be used. If interference is detected on the path, the
Velox LE Installation and Operations Manual
862-02411 February 04 2-5
GUI, via laptop connection, can be used to select a new channel plan (A , B, or C) to
“steer” around the interferer, or to create a new custom channel plan (Plan D) to avoid
the interference. SNMP network architecture, if employed, may also be used to make
the frequency plan changes. The frequency spectrum should be scanned over a
sufficient time period to ensure that periodic transmissions are recorded.
Interferers will cause problems if their amplitudes are less than 20 dB below the
intended receive power level. A link path loss calculation should be performed to
determine the expected receive power level.
The procedure for selecting the optimum antenna polarization and system frequency
plan is the following:
Perform a spectral analysis at each site in the link direction using a high gain
antenna.
Repeat the spectral analysis for vertical and horizontal antenna polarization.
Select the polarization with the lowest interfering levels as the system antenna
polarization.
Consult the Velox LE frequency channel plans (see Frequency Plans on page 8-5)
and select the frequency plan that would operate in an interference-free band.
Install the ‘High Band’ and ‘Low Band’ RFUs at the sites where they would
experience the lowest interference in their respective receive bands.
Microcell Backhaul Applications of Velox LE Digital
Radios
General
In applications where more than one independent and separate links, need to radiate
from a central site a number of parameters can be taken advantage of to provide
isolation and minimize interference between these links:
Frequency multiplexing
Antenna polarization
Choice of High Antenna Gain
It is important to note that these methods only provide isolation between two radio
Systems, and that power levels in the separate systems should be balanced to ensure
correct operation (see Transmitted Power Levels below).
Transmitted Power Levels
To minimize interference, received power levels should be balanced between separate
radio links. This means that transmit power levels should be set to provide similar levels
of received power, as indicated by the RSSI values of the adjacent receivers at the
central site. Power levels are easily adjusted via point and click selection utilising the
provided NCT / GUI, installed on your laptop or via SNMP network architecture.
Chapter 2. Planning
2-6 862-02411 February 04
Frequency Multiplexing
The Velox LE 2410, Velox LE 2410i, Velox LE 2450 and Velox LE 2450i each offer
three frequency channel plans, while the Velox LE 5810, Velox LE 5810i, Velox LE
5850 and the Velox LE 5850i offer four frequency channel plans. Refer to Frequency
Plans on page 8-5 for more detail on the frequency channel plans. A radio link requires
two channels (one for transmit and one to receive) to provide full duplex operation.
Each radio has a high and a low sub-band, one that it uses for transmission and another
for reception. Terminology definition: the ‘High -band RFU’ of a system transmits on
the higher of the two sub-bands. The ‘Low-band RFU’ of a system transmits on the
lower of the two sub-bands. A system (link) always has one High Band and one Low
Band RFU. It is important to note that unwanted transmitted signals in adjacent
frequency bands can affect other receivers operating in an adjacent band if insufficient
antenna isolation is provided. A solution is to group high-band or low-band RFUs at the
central site, rather than group high and low-band RFUs together.
Antenna Isolation
Separate links at a central site will have sufficient isolation when radio systems operate
outside the radiation beam width or side lobes of the system antenna. The achievable
isolation can be established by examining the measured radiation patterns of the system
antennas. Directional isolation can be used if the antenna radiation is 15 dB or lower
relative to the adjacent main beam. Antennas with high directionality will allow
reduced angular separation of adjacent systems. Antenna cross-polarization isolation
can be used for adjacent radio links, radiating in the same direction. Typical isolation
of 30 dB can be achieved using high quality antennas.

Balanced 120 Ohm and unbalanced 75 Ohm termination via RJ48 connectors are
available on the Velox LE 10 and Velox LE 25 DIUs. The standard termination is 120
Ohms on both DIUs. Unbalanced 75 Ohm is an optional termination, which must be
requested from the supplier when ordering the system
Although RJ48 Payload connectors are available on only the Velox LE 10 and
Velox LE 25 DIUS, RJ48 connections on the Customer interface can be connected
to the DB25 payload connector on the Velox LE 120 Ohm and 75/120 Ohm units
using the 4 E/T Spider Cable 660-03678, which is supplied as part of the
Accessories kit .
The pin connections for balanced 120 Ohms termination Table 3-3 on page 3-6.
For unbalanced 75 Ohm terminations, pins 2 and 5 should be connected to ground. For
this connection we recommend using a shielded cable together with RJ-48 shielded
connector. If this connector is used, pins 2 and 5 can be connected to the connector
body, which is grounded via the connector body of the mating RJ-48 connector on the
DIU.

Reset/Configuration Button (3)
You use the Reset button in conjunction with the Status LEDs when configuring the
radio. The LED which is ON and its colour when the button is released determines the
function. When the Reset Button is pressed, the Status LEDs will light in sequence RF,
PAYLOAD and SYSTEM. The LED colour sequence while the button is pressed is
GREEN, ORANGE then RED and then GREEN again, i.e. the sequence will repeat.
The LED colours and their corresponding functions are listed in Table 3-5 below.
If while pressing the Reset Button you “lose” the count, continue pressing until all the
LEDs are out. The sequence is now complete and you can start again from position 1.
Throughout this manual, use of the Reset Button is indicated in text by the LED
sequence number followed by the word RESET. For example, LED sequence 1 (RF
LED GREEN) is indicated 1-RESET, LED sequence 5 (PAYLOAD LED ORANGE) is
indicated 5-RESET, etc.

Chapter 4 : Hardware Installation
Introduction
This chapter covers installation procedures for all the Velox LE split-architecture radio
systems. All steps, from unpacking and checking the equipment, through to completion
of the physical installation and antenna alignment are addressed.
For a full description of the Velox LE systems, refer to the System Overview on page 8-
4.
Health and Safety
Velox LE Health and Safety Requirements
Ensure relevant health and safety practices are adhered to at all times, when working on
or around the Velox LE radio equipment. Table 4-1 on page 4-1 details the
recommended general health and safety practices. Table 4-2 on page 4-2 details
recommended operator health and safety practices.
Ensure the general hazards in Table 4-3 on page 4-2 are fully addressed at the planning
and installation stages.
General Health and Safety
Table 4-1. General Health and Safety Practices
Hazardous Materials No hazardous materials are used in the construction of the
equipment and, therefore, no special handling/disposal
procedures are required.
Hazardous Voltages The Velox LE 10 and Velox LE 25 takes up to 56/58V input to
the DIU and convert it to 64V nominal or up to 80V OC for RFU
power feed. The Velox LE 50 DIU meets SELV standards and
the RFU power feed is always be low 60V with a
nominal/average of 53V.
Safety Signs It is not necessary to place external warning signs or other
indications on the equipment.
Surface Temperatures While external surfaces of the equipment do become warm
during operation due to normal heat dissipation, the
temperatures reached are not considered hazardous.
Flammability The equipment is designed and constructed to minimize
the risk of smoke and fumes under fire conditions.
Chapter 4. Hardware Installation

Operator Health and Safety
Table 4-2. Operator Health and Safety Practices
Protection from RF
Burns:
Velox LE Radios
While the Velox LE radio does not generate RF fields of
intensity sufficient to cause RF burns, it is hazardous to look into
or stand in front of an active antenna aperture while the radio is
active.
Do not stand in front of or look into an antenna without first
ensuring the associated transmitter or transmitters are switched
off.
Protection from RF
Burns:
General
When any of the Velox LE ORFU is to be installed on a structure
or rooftop that has existing antennas fitted, avoid exposure to
potentially harmful levels of RF radiation from these antennas.
Do not proceed with an installation without first determining the
RF expo sure risk. If necessary ask the structure/rooftop owner or
operator. Where necessary, wear a protective suit or have the
required transmitter(s) switched off for the duration of the
installation.
Even where the perceived risk is low, do not stand in front of or
look into other antennas.
Lifting Equipment Care must be taken when hoisting or lifting the RFU or its
antenna during installation or maintenance. The RFU is
nominally 6kg (13.2lbs), but dependent on size, associated
antennas with their mounting hardware can weigh in excess of
100kg (220 lbs.), which will require specialised lifting equipment
and an operator trained and certified in its use.
Equipment Protrusions While the equipment has been ergonomically designed to be free
from unnecessary protrusions or sharp surfaces that may catch or
otherwise cause injury during handling, always take care when
working on or around the equipment.
Safety Warnings When a particular practice or procedure poses implied or
potential harm to the user or to the radio equipment, a warning is
included in this manual.
General Hazards
The General hazards to be addressed when planning and installing a Velox LE system
are detailed in Table 4-3.
Table 4-3. General Hazards
Maximum ambient
temperature The maximum ambient temperature (Tmra) for the Velox LE
DIU is +50° Celsius.
The maximum ambient temperature (Tmra) for the Velox LE
ORFU is +60° Celsius and for the Velox LE IRFU is +50°
Celsius. Compliance to the operational specification is not
guaranteed for higher ambient temperatures. To ensure correct
operation and to maximize long term component reliability,
ambient temperatures must not exceed this figure.
Rack mount
temperature
considerations
If the Velox LE type DIU and IRFU are installed in a closed or
multi-unit rack assembly, the operating ambient temperature of
the rack environment may be greater than room ambient. The
maximum ambient temperature (Tmra) of +50° Celsius applies to
the immediate operating environment of the Velox LE DIU and
IRFU, which if installed in a rack, is the ambient applying within
the rack.
Airflow requirements Rack installations must be made so the airflow required for safe
and correct operation of the Velox LE is not compromised. For
the Velox LE, unobstructed air passage must be maintained to
Velox LE Installation and Operations Manual
862-02411 February 04 4-3
each side of the indoor units, which requires a minimum of 50
mm (2 inches) of side spacing to any rack panels, ca ble bundles
or similar.
Circuit overloading Consideration must be given to the connection of a Velox LE to
existing dc supply circuits and the effect that overloading of
circuits might have on the power supply, circuit protection
devices and supply wiring. Check the Velox LE power
consumption specifications and the supply capability of the
power supply system when addressing this concern. This check
of capacity must extend right to the dc power supply and not just
to an intermediate connection point.
Power supply connection The Velox LE radio must be used with correct power supply (21-
56 Vdc power supply or 21 58 Vdc power supply as indicated).
The power supply must be located in the same premises as the
Velox LE system.
Earth connection Reliable earthing of the Velox LE system must be maintained.
Refer to instructions in the manual for earthing of the ODU,
ODU cable, lightning surge suppressor and indoor unit.
Lightning surge
suppressor
All Velox LE RFU cables must be fitted with a lightning surge
suppressor.
Refer to instructions in the suppressor supplier’s documentation
for suppressor installation information.
Mechanical loading When installing the DIU and IRFU in a rack, ensure the rack is
securely anchored. Check to ensure that the additional loading of
a Velox LE DIU or units will not cause any reduction in
mechanical stability of the rack.
Restricted access The Velox LE system must be installed in restricted access sites.
The DIU and associated power supply must be installed in
restricted areas, such as dedicated equipment rooms, closets,
cabinets or the like. Similarly, access must be restricted to the
RFU/antenna location.
In particular, install and operate a Velox LE system in accordance with the following
statements and warnings:
An appropriate power supply disconnect device should be provided as part of the
building installation.
!
WARNING
The Velox LE system has been evaluated for safety with the maximum allowed for
the system, i.e. 56 Vdc or 58 Vdc depending on the system.
!
WARNING
The Velox LE type DIU earth must be connected directly to the dc supply system
earthing conductor, or to a bonding jumper from an earthing terminal bar, or bus to
which the dc supply system earthing is connected.
!
WARNING
The Velox LE type system must be located in the immediate area, such as in the
same or adjacent cabinets, of any other equipment that has a connection to the same
earthed conductor of the same dc supply circuit. The Velox LE dc system must not
be earthed elsewhere.
!
WARNING
The dc supply source must be located within the same premises as the Velox LE
system.
Chapter 4. Hardware Installation
4-4 862-02411 February 04
!
WARNING
There must be no switching or disconnecting devices in the earthed circuit and the
point of connection to a Velox LE system.
!
WARNING
Do not look into or stand immediately in front of an active antenna.
!
WARNING
Never install an ORFU on a structure, rooftop or the like where there are existing
antennas without first ascertaining the RF exposure risk from the existing antennas,
and where necessary taking appropriate risk avoidance action.

All 3 Front Panel LEDs should be green. Note that “RF Link” LED
may flash orange from time-to-time. See Note below for “Payload”
LED indication.
Unless all tributaries are in use the “Payload” LED will be RED. For example, if
only two tributaries are in use, but all four are active, the “Payload” LED will be
RED, as the two unused tributaries have no signal. This is not important, as the main
purpose of this test is to test the link, i.e. “RF Link” LED GREEN.

Velox LE Installation and Operations Manual
862-02411 February 04 4-17
Install the RFU mounting bracket onto the antenna mast. Note that the mast
diameter must be between 50 mm (2”) and 102 mm (4½”).
Mount and secure the RFU on the mounting plate.
The ORFU may be mounted indoors, utilising an optional rack mount adapter (not
included as a standard item) at the base of a tower for convenient access. However,
before using this method consideration must be given to the distance between the RFU
and the antenna as long lengths of RF cable could have a compromising affect on
system sensitivity. In addition, link costs would increase due to the high cost of such
cable.
!
CAUTION
Ensure that the Antenna Mast is adequately grounded for Lightning Protection.
Follow these steps to install the RFU:
1. Install the system antenna in accordance with the manufacturer’s instructions.
2. Unpack the RFU mounting bracket assembly from the accessories box:

Installing the IRFU
The Velox LE 2410, Velox LE 2450, Velox LE 5810 and Velox LE 5850 outdoor
RFUs are also available as 1RU high IRFUs, Velox LE 2410i, Velox LE 2450i, Velox
LE 5810i and Velox LE 5850i, that can be rack mounted in a 19” rack.
Note that when installing an IRFU consideration must be given to the distance between
the IRFU and the antenna as long lengths of RF cable could have a compromising affect
on system sensitivity. In addition, link costs would increase due to the high cost of such
cable.
1. Install the IRFU as follows:
Slide the IRFU into the 19" rack and secure to the rack using four (4) M6 x 18
mm screws and washers provided.
Ground the IRFU by connecting the ground cable or strap between the station
ground and the ground terminal on the IRFU front panel.
2. Install the system antenna (see Installing the Antenna on page 4-16). Note that the
RSSI BNC connector is on the front panel of the IRFU.
3. Connect IRFU to antenna noting the following:
Connect the RF cable or waveguide outer conductor to the pole lightning earth
electrically before it enters the building in which the equipment is housed.
Connect the type-N RF output connector on the front panel to the system
antenna through an inline lightning protection unit.
The N -Type connector is used to connect to the antenna, typically using
coaxial transmission line or flexible waveguide via a launch/N-type adaptor.
1/2" or 5/8” coaxial cables are recommended. Coaxial cable that is 7/8” or
larger can exhibit "moding" at 5.8 GHz and is not recommended for 5.8 GHz
radios.
Do not use right angle N-type connectors with the radios: they may present
high loss.
Do not use low quality cables. Some cable types, such as RG-8, may have too
high a loss at 5.8 GHz.
Elliptical waveguide is recommended for longer feeder runs to minimize
losses.
4. Weatherproof the connectors using an ultra violet protective, self-vulcanising tape.
!
CAUTION
Ensure that the Antenna Mast is adequately grounded for Lightning Protection.
Installing the DIU

The front panel RF Link LED, the Received Signal Strength Indicators (RSSI: on
NCT, via SNMP or as an Electrical signal on the RFU), Carrier-detect (NCT,
SNMP) and Frame Lock (NCT, SNMP) indicators are available to assist with link
installation and alignment.
NOTE 1 For the Velox LE 2400, Velox LE 5800, Velox LE 2410i and Velox LE
5810i RFUs, the RSSI values displayed in the MIB are representative of the signal
level measured over a 200kHz BW. Add ~20dB to the MIB value for a wanted
spread spectrum signal. The NCT / GUI will do this adjustment automatically and
will therefore always display the correct RSSI value.
NOTE 2 Due to the technique used to calculate the RSSI level of a wanted signal,
the measured RSSI level can differ from the actual value with up to ±3 dB.
Set Transmitted Power Level
It is good practice to match received power levels by adjusting transmitted powers
if co-located systems are being installed. This is important to avoid interference
between co-located systems. An attenuator can be fitted between the RFU and the
antenna if the power level cannot be sufficiently reduced. The dBm output at the
RFU N-type connector (socket) levels are set-up via the NCT or using a SNMP
Management application.
Diagnostics (Loopback Modes)
This section describes the usage of the loop back modes.The purpose of loop back is to
return the payload data to its sender, thus looping it back. The payload data is never sent
to the other radio in the link. This can be done at two stages in the Velox LE products;
Baseband/IF Loopback
BaseBand loopback loops the payload data back to the sender just before it reaches the
radio’s RF-modem. BaseBand loopback can be used to verify all the data cables and
connectors and the radio’s interface circuitry.
RF Loopback
RF loopback loops the final transmitted microwave signal back to the radio’s
microwave receiver. RF loopback verifies the RF-modem and the transceiver line-ups.
The RF loop back works best in Band Plan B; using it in other band plans is not
guaranteed to work.
!
CAUTION
The signal does reach the antenna connector and is thus still transmitted if an
antenna is connected.

NCT Software Installation
Scope
This section provides brief instructions on how to install the Velox LE NCT. A detailed
HTML-based help document can be found on the NCT installation CD supplied with
new radios.
Introduction
The purpose of the Network Configuration Tool, hereafter called the NCT, is to allow
you to configure, manage or interrogate the following primary functional elements of a
Digital Radio Link:
DIU
RFU
The NCT is a PC-based software package that provides you with a graphical interface
that is used to perform on-site element management of a digital radio system. It allows
you to configure, manage and interrogate the system by selecting various menus and
options.
The NCT comprises hardware and software, whichis known as the NCT Terminal.
The NCT Terminal is the principal system support equipment associated with the radio
for system installation and commissioning.
The NCT connects to a designated NCT Terminal port (ELEMENT MANAGER) on
the front panel of the DIU, by means of a serial data interface (supplied Lap Link
Cable). It can also connect to any number of DIUs interconnected through an IP
network.
The NCT communicates with SNMP agent software that is contained in each DIU. The
NCT communicates with the agent’s software: the software enables a unit to interpret
Chapter 5. NCT Installation
5-2 862-02411 February 04
MIB (Management Information Base) commands via SNMP (Simple Network
Management Protocol).
The NCT application supplied with older Velox LE radios have been replaced with
the Java-based Velox LE NCT. The o lder NCT does not support the new Velox LE
series radios and it is highly recommended to replace the old NCT with the new
NCT version.
System Requirements
The system requirements for the Velox LE NCT PC are as follows:
P III 450 MHz or higher CPU
128 MB RAM
20 MB Free Hard disk space
CD-ROM Drive

Upgrades
Velox LE FTP Firmware Upload
Firmware Upload
Firmware can be uploaded to Velox LE DIUs using FTP uploads as well as by using the
"CVF Loader" or NCT software, available on the software CD or from the distributor.
Note the following:
Username : anonymous
Password : guest
The relevant MIB info is in the "mdrmteConfiguration" GROUP
1.3.6.1.4.1.1316.1.1.1.2.5 mdrmteFirmware.
1.3.6.1.4.1.1316.1.1.1.2.5.1 mdrmteFTPServerStatus. By default the DIU FTP
server is active.
1.3.6.1.4.1.1316.1.1.1.2.5.2 mdrmteFlashNewFirmware. By default the upgrade is
immediate (it can also be timed).
We recommend that the user ALWAYS verifies that the new version has been uploaded
and is being used by the DIU. To do this verification, check the following element:
1.3.6.1.4.1.1316.1.1.1.2.4.3 mdrmteIUFirmwareVersion
This OID (object ID) is part of:
1.3.6.1.4.1.1316.1.1.1.2.4 mdrmteGeneral, part of the "mdrmteConfiguration"
GROUP
When updating the DIU firmware by means of FTP, note that the choice of IP address is
very important. You must always choose the IP address of the interface "closest" to
you. In other words if you are using Ethernet to connect, then use the IP address of the
Ethernet Interface, e.g. 192.168.1.2 for NEAR DIU in a Bridged configuration. See
Chapter 7. Maintenance and Radio Upgrades
7-2 862-02411 February 04
IP Configuration of the Velox LE on page 6-7 for information on IP addresses.
If you are updating the firmware on the FAR unit, use the IP address of the
"overhead" PPP link - NOT the Ethernet interface of the FAR unit. For example,
use 192.168.4.3 when uploading to the FAR side and using the Bridged
configuration. If by mistake you use the wrong address, you will create a "half-
established" FTP session, and NO FURTHER SESSIONS will be permitted until the
session times out after some minutes.
Set-up for Full Duplex Mode (at Maximum Transfer Rate)
Set-up the Velox LE radio in Full Duplex mode as follows:
1. Upload the radio Firmware by following the aforementioned procedure. Full
duplex Ethernet operation is supported from version 2 of the firmware.
2. Using the Rest Button set the required default configuration. 7-RESET and 8-
RESET for Bridged Configuration and 4-RESET, 5-RESET and 6-RESET for
Routed Configuration (see Table 3-5 on page 3-7 for full details of default
configurations).
3. Ensure that the PCB revision of the DIU is issue_2_mod_a(3) by reading the
following MIB element: 1.3.6.1.4.1.1316.1.1.1.2.4.15
mdrmteIndoorUnitPCBrevision. If the PCB revision is issue_2(2) the radio
hardware does not support Full Duplex Ethernet mode.
4. Disable all tributary channels to make the maximum user bandwidth available for
Ethernet traffic.
5. Enable Full Duplex mode via the MIB using element: 1.3.6.1.4.1.1316.1.1.1.4.16
mdrmteEthernetFullDuplex.
6. Set the data rate to T1 if required using MIB element: 1.3.6.1.4.1.1316.1.1.1.2.1.1
mdrmteDataRate.

862-02411 February 04 7-3
Tributary Upgrading
The tributary configuration code determines the software capabilities of the radio and is
unique to every radio. This code has a very specific structure and must be entered
exactly the same as was provided by the manufacturer. The preferred way to enter this
tributary configuration code is to copy and paste it from the document in which it was
provided, by using the Ctrl-C and Ctrl -V shortcut keys for copy and paste. A tributary
configuration code may be entered only once. If an invalid code is entered, and the
Apply button is pressed, the radio will appear t o accept the code. The code will
however, not take effect and will be replaced by the previous valid code when the radio
is reset.
Install a new tributary configuration code as follows:
1. Open the document that contains the tributary configuration code and copy the
code.
2. From NCT, access the NCT drop-down menu and select the Configuration/Station
Properties option.
3. Paste the tributary code in the Configuration Code box.
4. Click Apply.

Chapter 8 : Technical Information
Radio Description
Introduction
The Velox LE 24/5800, Velox LE24/5810 SR and Velox LE24/5810 SRi are ISM band
digital radio systems that provide short to medium range, point-to-point digital
communication with high data security at rates of T1, 2T1 or 4T1. Alternatively, the
radio can be software configured to convey E1, 2E1 or 4E1. The radio can also be
configured to bridge or route IP via a 10Base-T port. The data rates scale depending on
the number of enabled T1/E1 tributaries and whether the data is being bridged or
routed. The products make use of spread spectrum technology and may be operated
license-free in the 2.4 GHz and 5.8 GHz ISM bands.
The Velox LE 24/5825 SR, Velox LE 24/5825 SRi, Velox LE 24/5850 IP, Velox LE
24/5850 IPi, Velox LE 24/5850 SR and Velox LE 24/5850 SRi are similar radios also
operating in the 2.4 and 5.8 GHz ISM bands respectively. Modulation can be switched
between 16 and 32 QAM with digital output scalable up to 16 T1/E1 tributaries
depending on the specific radio.
The radios are ideal for applications such as:
Cellular/PCS base station interconnects.
Telecommunications companies, cellular operators and private carriers.
State Local and Federal Government communication systems.
Video surveillance data distribution.
Power utilities.
Petroleum/gas collection companies.
Rural communications.
Emergency/disaster telephone service restoration.
Internet distribution.
Control and Management
There are two options to control the Velox LE products via SNMP:
Using any open-standard -compliant SNMP Management package, e.g. HP
OpenView, SNMPc etc. Using a MIB Browser provides access to the full
compliment of the MIB elements of the Velox LE.
Using the Network Configuration Tool (NCT) application package supplied. The
NCT provides control and management of the product although not to the full
complement of the MIB element. SNMP support via an SNMP agent in the DIU
Chapter 8. Technical Information
8-2 862-02411 February 04
ensures open network management compatibility. The NCT has a Graphical User
Interface (GUI) carefully designed to assist installation and maintenance staff.
Comprehensive data and RF loop-back functions ensure that the system is easy to install
and maintain.
Velox LE Models
Each radio in the system consists of two main parts:
A Radio Frequency Unit (RFU) operating in the 2.4 GHz or 5.8 GHz ISM
frequency bands. The RFU has an N -type female connector for connection to a
range of antennas and can either be and Outdoor RFU (ORFU) or and Indoor RFU
(IRFU).
RFU units available are the Velox LE 2410, Velox LE 5810, Velox LE 2410i,
Velox LE 5810i, Velox LE 2450, Velox LE 5850, Velox LE 2450i and Velox
5850i units. The models with an “i” suffix are 1RU high IRFUs. See RFU Variants
on page 9-1 for further inform ation.
A Digital Indoor Unit (DIU), available with a Telecommunications interface (0 to
16T1/E1 tributaries depending on the radio)and a Data interface (10Base-T
Ethernet or 10/100Base-T Ethernet, depending on the radio).
DIU units available are the Velox LE 75/120 Ohm, a Velox LE 120 Ohm, Velox
LE 10, Velox LE 25 or a Velox LE 50 unit. All DIUs operate with the Velox LE
2410/2410i and Velox LE 5810/5810i RFUs. Velox LE 10, 25 and 50 DIUs can
operate only with the Velox LE type 2450 and 5850 RFUs. With the exception of
the Velox LE 75/120 Ohm and Velox LE 120 Ohm units the number is a guide to
the maximum data capacity of the unit. For example, the maximum data capacity of
the Velox LE 25 is 25 Mbps. DIU Variants on page 9-1.
Interconnection between the RFU and DIU is achieved using a low-cost UV-protected
STP (Screened Twisted Pair: 4 pairs) data cable and an UV-protected 2-core power
cable. The split DIU and RFU configuration is used for the lowest loss between the
antenna and the transceiver, thereby ensuring optimal long-range performance.
The RFUs use a Type-N RF (female) output connector for connection to a coaxial cable
jumper when co-located with a 2.4 GHz or a 5.8 GHz antenna for applications where
long range is required.
The RFU can also be located remote from the antenna (tower base or indoor mounted).
The RF connector is then connected to the antenna via either a coaxial transmission line

Velox LE SR 8 x T1/8 x E1 and 10Base-T Ethernet functionality:
Depending on the radio model and RFU configuration, the Velox LE radio can
simultaneously support 1 to 8 E1 or T1 tributary channels, with the balance of the
available user BW made up by Ethernet packet data, up to a maximum aggregate
Ethernet throughput no greater than 9.5 Mbps (Combined up - and downstream
throughput). The unidirectional Ethernet throughput of the radios is limited to a
maximum of 8 Mbps, which decreases as more tributary channels are activated.

Figure 8-1. Velox LE Digital Radio Link
The radio station consists of two main parts:
An RFU operating in the 2.4GHz or 5.8 GHz ISM frequency bands. The RFU
provides t he radio transceiver functionality by accepting radio link data from the
DIU and converting it to the 2.4GHz or 5.8 GHz ISM frequency band using spread
spectrum or QAM modulation. The received signal is de-modulated and
transmitted to the DIU in a digital format.
A DIU, available with 0, 1, 2, 4, 8 or 16 T1 or E1 data interfaces (choice of T1 or
E1 is software selectable). The DIU combines nT1 or nE1 data with Wayside
Service Channel serial data and link IP data to be transmitted across the radio link.
The DIU also provides power to the RFU. In the Velox LE 50, the E1/T1 data
interface is provided through an optional Interface Card.
Interconnection between RFU and DIU is achieved using low cost data and power
cables.
RFU
The Velox LE 2410, Velox LE 5810, Velox LE 2410i and Velox LE 5810i RFUs make
use of Spread Spectrum modulation technology for license-free operation in the 2.4GHz
and 5.8 GHz ISM bands.
The Velox LE 2450 RFU uses three software selectable bandwidths for license-free
operation in the 2.4 GHz ISM band. The Velox LE 5850 RFU uses three software
selectable bandwidths for license-free operation in the 5.8 GHz ISM band.
All the RFUs with the postfix “i” (e.g. Velox LE 2410i and Velox LE 5810i) have been
repackaged into 1RU units that should be used in indoor unit applications only. Please
refer to Installing the IRFU on page 4-19 for more detail.
For operation, the ISM bands are divided into upper and lower frequency sub-bands. A
‘High Band’ RFU transmits in the higher frequency sub-band and receives in the lower
frequency sub-band, while a ‘Low Band’ RFU transmits in the lower sub-band and
Velox LE Installation and Operations Manual
862-02411 February 04 8-5
receives in the higher sub-band. A Velox LE radio link will use a ‘Low Band’ RFU on
one end of the link to communicate with a ‘High Band’ RFU on the other end.
The RFUs use a Type-N RF output connector for connection to suitable 2.4GHz and
5.8GHz antennas for applications where long range is required.
The system is available for use in FCC regulated countries.
Frequency Plans
General
The Velox LE 5810, Velox LE 5810i, Velox LE 5850 and the Velox LE 5850i RFUs
operate in the 5.725 GHz to 5.850 GHz ISM frequency band with predefined frequency
channel plans (termed A, B, C and D). Channel plan D is user selectable/adjustable.
The Velox LE 2410, Velox LE 2410i Velox LE 2450 and the Velox LE 2450i RFUs
operate in the 2.400 GHz to 2.4835 GHz ISM frequency band with p redefined
frequency channel plans (termed A, B and D). Channel plan D is user
selectable/adjustable.
Velox LE 5810 and Velox LE 5810i Frequency Channel Plan A, B and C
Refer to Figure 8-2 below. The channel spacing is based on the bandwidth occupied by
the spread spectrum signal (approximately 17 MHz) and is used to optimize link
performance. Note that for plan A, plan B and C, both RFUs in a link must be set-up to
the same frequency channel plan (i.e. A, B or C).

Frequency Channel Plan D (FCC Compliant)
Fr equency plan D allows independent control of transmit and receive frequencies. This
allows a flexible frequency plan and can be used to overcome interference in the
2.4GHz and 5.8 GHz ISM bands.
The frequencies that can be used in the lower or upper sub-bands can be selected in 1
MHz increments. Performance degradation can be expected when operating using
channel plan D mode with the chosen frequencies close to the sub-band edges, i.e. a
choice of one of the high frequencies in the lower sub-band and one of the lower
frequencies in the upper sub-band.
The allocation of Channel plan D frequencies is shown in Table 8-4, Table 8-5, Table
8-6 and Table 8-7 below. The Velox LE 24/5850 RFUs have up to four different sets of
minimum and maximum frequencies, which are determined by the data rate setting of
the RFU.
Only channel frequencies that are FCC compliant can be selected through the
configuration software. The channel frequency ranges are programmed into the radio
firmware and cannot be adjusted by the user.
The radios were tested and approved for FCC compliance with the frequency ranges in
Table 8-4 below.

Indoor Unit
General
The Digital Indoor Unit (DIU) is designed for mounting in a 19” rack, occupying a 1RU
slot. It can also be used as a tabletop system.
The DIU accepts n x T1/nE1 user payload channels and combines it with Wayside
Service Serial Data and IP data to be transmitted across the radio link.
The DIU is fitted with a DC power supply.
There are five types of DIUs:
Velox LE (120 Ohm) (scaleable up to 4 T1/E1) (see Figure 8-8 below).
Velox LE (75 / 120 Ohm) (scaleable up to 4 T1/ E1) (see Figure 8-7 below).
Velox LE 10 (scaleable up to 4 T1/E1) (see Figure 8-9 below).
Velox LE 25 (scaleable up to 8 T1/E1) (see Figure 8-10 below).
Velox LE 50 (with optional 16 T1/E1 interface card) (see Figure 8-11 below).
The Velox LE DIUs can operate with the Velox LE 2400, Velox LE 5800, Velox LE
2410i and Velox LE 5810i RFUs.
The Velox LE 10 / 25 and 50 DIU is used with the Velox LE 24/5850 RFU, but can
also support the Velox LE 24/5800, and Velox LE 24/5810i RFUs if the appropriate
firmware version is loaded on the DIU.

Chapter 11 : Domain/Network
Management of the Velox LE Product
Range
Introduction
All management of the Velox LE products are implemented using SNMP (Simple
Network Management Protocol), an open standard. The products can be managed by:
a. Standard SNMP managers such as HP OpenView or SNMPc, i.e. there is Open
Network Management compatibility.
For rapid product installation, the NCT GUI Application (hereafter referred to as the
NCT-GA) provides extensive management functions on site and, via the microwave
radio link, can be used to access the Velox LE station on the opposite side of the link.
The NCT -GA is a software application that runs on a PC workstation such as a laptop
or notebook computer that is connected to a Velox LE DIU serial port (DB9 DTE) or an
Ethernet connection (10Base-T DTE), both accessed via the DIU front-panel.
NOTE: The lates NCT can be downloaded from www.stratexnet.co.za/updates
SNMP and the Velox LE
Use of SNMP within the product allows remote: configuration, monitoring of
performance, notification of alarms and firmware upgrades via an IP-network. Within
an IP network supporting routing of IP data, the radios can be supported from any
remote location. The product can be accessed via the Internet if the necessary gateways
are provided. A GSM/PCS modem dial-up capability provides another remote
management option.
The DIUs have built-in SNMP agents and an extensive MIB (Management Information
Base). The Velox LE product uses SNMP V1 (RFC1155, 1157). The user has access
to an Enterprise MIB (obtainable Stratex Support see Support on page 1-4 for details)
and MIB II (RFC 1213).
Access to the MIB via the DIU SNMP agent is via Ethernet (10Base-T interface on the
product's front panel) or PPP (RFC 1661) via the product's serial channel Element
Manager Port. The use of SNMP provides flexibility for operators with central
equipment monitoring. It provides management access to radio configuration (all data
interfaces), interface status and statistics, fault and maintenance information.
Using a login and password to give the user “administrator” or “standard user” rights (if
enabled) ensures SNMP security. The "standard user rights" option limits the ability to
SET MIB variables.
Chapter 11. Domain/Network Management of the Velox LE Product Range
11-2 862-02411 February 04
NOTE: Secure SNMP is not supported.
The product has threshold-based alarm generation (there is an extensive SNMP trap list
with a trap filter that is adjustable via SNMP). Network access (wired or wireless i.e.
GSM/PCS Modem) allows over-the-air remote firmware uploading (FTP) with a load
verification (and reversion) capability.
There are three principle requirements to use SNMP with the Velox LE Radio Stations:
a. A Management Station that runs a SNMP Management Software package that is
installed on a networked or stand-alone PC that can be connected to a DIU either
using a serial connection or an Ethernet connection. From the Management
station, the agents within the DIUs can be configured or polled for information.
b. Agent: The agent accepts SNMP GET, SET or GET-NEXT commands from the
Management Application software and collects or adjusts information from the
DIUs MIB.
c. Management Information Base (MIB): the MIB is a database that is accessed
based on the OID (object ID) the SNMP Manager has chosen. The DIU uses an
Enterprise MIB and a standard MIB (MIB II) to store or allow access to
information relevant to the Velox LE link.
MIB Elements OID (Object ID) Descriptions
NOTE: The MIB database is updated on a regular basis. Information on the latest
additions can be obtained from www.stratexnet.co.za/firmware.

Chapter 12 : 1+1 Protection System
Operation
System Description
When a single radio link is used to convey user data, any number of unexpected events
may cause the link to fail resulting in user data being lost. This would require
immediate corrective actions from the network operator responsible for maintaining the
radio link. Since such a failure may occur at any time and possibly at a remote location,
corrective actions may be very costly, both in terms of downtime and human resources.
Common reasons for radio links to fail are:
Signal fading on the radio link
The presence of strong in-band interference
Equipment failure
One possible solution to this problem is to install a second redundant radio link that can
automatically take over the function of the primary radio link. This not only reduces
the downtime of the link, but also provides the network operator with the opportunity to
repair the faulty link at a convenient time.
This document describes the one-plus-one redundancy system that can be used with the
radio products of Stratex Networks. Radio systems that are currently supported by the
system are:
Velox LE 2400, Velox LE 2410 SR, Velox LE 2410 SRi
Velox LE 5800, Velox LE 5810 SR, Velox LE 5810 SRi
Velox LE 2425 SR, Velox LE 2425 SRi
Velox LE 5825 SR, Velox LE 5825 SRi
This document includes a detailed technical description of the redundancy system and
contains informat ion on its installation.
Technical Description
System Overview
General
The functionality required to provide a protected radio link is built into the Velox LE-
type Software Radios. This implies that the user can set up a protected radio link by
interconnecting the equipment for two parallel radio links through a 1RU-protection
panel and a dedicated communications cable.
Chapter 12. 1+1 Protection System Operation
12-2 862-02411 February 04
Each DIU in a protected radio system continuously monitors the status of the radio link
it uses, as well as the radio link provided through the redundant system running in
parallel. DIUs forming part of a redundant link at each end of the radio link share status
information through a cable connecting the two Auxiliary ports of the DIUs.
Only the tributary payload data channels are protected by the redundant link i.e. there is
no protection for Ethernet data. Tributary payload data is split and combined between
links through a 1RU-protection panel that connects to the user network equipment as
well as the two DIUs used at each end of the redundant link. Although both radio links
are functioning continuously, only one of the DIUs is actively driving the tributary
channels of the user network at any given time.
Each DIU continuously monitors the level of t he Packet Error Ratio (PER) for the radio
link on which it is receiving user data. When the PER exceeds a predefined ratio of 10
consecutive seconds, the DIU driving the tributary channels of the user network will
signal the redundant DIU to take over processing the data it receives over the radio link.
The value of the PER threshold is configurable and can be changed through the Velox
LE NCT if required. The default value is set at 30%.
There is no notion of a primary and secondary link in this redundancy system. The first
link to be configured successfully will start driving the tributary payload channels.
Switch over will only take place when the aforementioned condition occurs. In the
event where the link to which the data was switched over fails at a later stage, the
system will attempt to switch the data back to the original link.
NOTE 1: A situation can arise where the up - and downstream user tributary data is
carried by separate radio links, i.e. link A carries the upstream data, and link B
carries the downstream data.
NOTE 2: Due to the architecture of the redundancy system, the process of
switching over from one link to another is not hitless and user tributary data will be
lost for a few seconds (< 10).
System Configuration
The block diagram in Figure 12 -1 on page 12-3 illustrates a typical redundancy system
configuration. Note that this system is managed over an Ethernet LAN, where the two
local DIUs are connected to the LAN using a hub. It is important to note that the IP
addresses for each DIU should be unique. It is however possible to configure each link
in the redundant system separately through the Element-Manager port of each local
DIU, in which case it is not necessary to assign unique IP addresses to the DIUs.
The block diagram in Figure 12 -1 also illustrates the following interfaces:
DIU A to DIU B connection through the respective Auxiliary ports of the four
DIUs
The Protection Panel interfaces on each side of the link that combines and splits the
tributary payload channels between the two radio links
The single user network interfaces provided by the Protection Panel
The two radio links that provide the redundancy required for user data protection

where the Radio Links are Managed through an Ethernet Network
1RU Protection Panel
There are two types of protection panels: a four and an eight tributary channel panel.
They operate in the same way and perform the signal splitting and combination
functions for the tributary channels taking part in the redundancy protected radio
system. Note from Table 12-1 that the Protection Kit is currently only provided in 110-
ohm as a compromise to make provision for E1 and T1 mode.

DIU Interface 2xDB-25 110 ohm
The cables required to connect the Patch Panel to the two DIUs are provided with the
Patch Panel. The DB-25 pin-outs used for each DB-25 connector on the patch panel are
exactly the same as that of the Velox LE DIUs respectively.
Auxiliary Port Communication
The two DIUs on each side of the radio link share status information through the two
relay outputs and OPTO inputs on the Auxiliary (AUX) port of each DIU. Information
shared by each of these:

Indication if the DIU is currently driving the tributary channels on the user network
The current Frame Lock status detected by the DIU for the radio link it is using
System Functional Description
Each DIU taking part in a protected radio link continuously monitors the PER of the
radio link it is receiving tributary data over. If the PER for the link increases above the
Sever Error Margin for more than 10 consecutive seconds, the DIU will request the
second DIU to take over the driving of the tributary channels if the second DIU sees a
frame lock.
Once the second DIU has started driving the tributary channels, the first DIU becomes
the redundant link.
The flow diagram for the algorithm that governs the protection switchover process in
each DIU is illustrated in Figure 12-2 below .

Radio Software Configuration
Two MIB elements are used to configure the radios taking part in the protected radio
link. T hese MIB elements can be set using any SNMP element manager application, or
through the Velox LE NCT application. Please refer to the following for details on
using the above applications:
Velox LE NCT HTML help file.
3rd party user manual (If a 3rd party SNMP element manager / MIB browser is used.
Set the following MIB element in all DIUs taking part in the protected radio link to 1
(Yes). MdrmteOnePlusOne (OID: 1.3.6.1.4.1.1316.1.1.1.2.4.17, Parent:
MdrmteGeneral)
The MIB element controlling the switch -over threshold, MdrmteSevereErrorMargin
(OID: 1.3.6.1.4.1.1316.1.1.1.2.2.18, Parent: MdrmteRFLinkConf), is set to 30% by
default. This value is a percentage and represents the switchover threshold for the
Packet Error Ratio (PER). When the PER exceeds 30%, the switchover will occur. The
value of this MIB element can be adjusted to meet the exact user requirements. It is
advisable to set the switchover threshold on all DIUs to the same value.

System Verification
Since most of the functionality of the protected system is hidden from the user, it may
be difficult to monitor the status at times. It can however be determined by monitoring
the MIB elements listed below.
The status of the protected link can also be monitored through the Velox LE NCT.
Please refer to the Velox LE NCT user manual for more information on this option.

Chapter 13 : Frequently Asked
Questions (FAQ)
General FAQs
Q Can I operate several Velox LE radios in the same location?
A Yes. Up to 6 links (hops) have been operated from a single location. Please be advised
that inter-radio isolation considerations must be adhered to. This includes considerations
related to antenna transmission characteristics.
Q Can I use back-to-back RFs to make a straight repeater?
A Yes. Make sure to use either 2 high band or 2 low band radios at the same location.
Q Does the Velox LE provide channel banks or multiplex to “break down”
T1’s to DSO’s?
A No
Q Has the Velox LE been connected to a PBX with E1 interface?
A Yes. A Velox LE link conveys Primary Rate data transparently.
Q How does the Velox LE series equipment deal with interference?
A The Velox LE incorporates processing gain (through use of a spread spectrum technique).
This provides interference immunity.
Q What is the weight and dimensions of a packed Velox LE product?
A Velox LE 5800 and Velox 2400: 17.5 Kg (38.5 lb.) 57cm x 32cm x 42cm (weight
includes mounting brackets and manual).
Support FAQs
Q Do you have 24 hour 7 day technical support if I have a radio failure?
A Technical support queries should be routed to the supplier from whom the equipment was
purchased. As accredited distribution/sales channels, they are trained to deal with the
majority of technical support issues. Should it be required, they will escalate the issue to
Stratex Networks that has a worldwide support network. For informatio n on Stratex
Networks support facilities refer to Support on page 1-4.
Chapter 13. FAQ
13-2 862-02411 February 04
Q Where do I call for technical support?
A Your first call should be to the supplier from whom the equipment was purchased. As
accredited distribution/sales channels they have been trained to deal with the majority of
technical support issues which may arise. Should it be required, they will escalate the
issue to Stratex Networks itself. For information on Stratex Networks support facilities
refer to Support on page 1-4.
Q For protected systems, can I use a double feeder antenna?
A Yes, two independent links are used for a protection system. Stratex Networks suggest
using two different Tx frequencies. Essentially providing polarization diversity.
Q How do I upgrade my Velox LE 2400 or Velox LE 5800 radio from 1E1/T1 to
2 and 4 E1/T1?
A A tributary code must be purchased. You use the NCT, a graphical utility to "load" the
tributary code into the DIU. Thereafter, extra tributaries can be activated. See Chapter 5:
NCT Installation for information on the NCT and Chapter 7:Tributary Upgrading.
Q What T1/E1 configuration do I order if I only want to use radio for maximum
capacity (10 Mbit) Ethernet?
A Radios with a single T1/E1 active are all that are required to provide this capacity. You
then deact ivate the tributary using the graphical software utility supplied with the Velox
LE radios.
