11. Protected Terminals
Monitored Hot Stand By (MHSB)
This section describes configuring the protected terminal in MHSB mode.
A protected terminal in MHSB mode comprises two radios interconnected using a MHSB switch. This MHSB
switch comprises one RF switch and up to four tributary switches depending on the number of tributaries
requiring switching:
The MHSB switch protect terminals against any single failure in one radio. It also monitors the alarm
output of each radio and switches between radios if major radio link alarms occur. The MHSB switch will
not allow a switch to a faulty radio.
The MHSB switch uses a CPU to monitor the alarm status received from both the connected radios' alarm
ports. When a relevant major radio link alarm is detected on the active radio (that is, transmitter,
receiver, power supply or modem), the CPU switches a bank of relays that switches all the interfaces and
the transmit port from the main radio to a functioning stand-by radio. The stand-by radio now becomes
the active radio.
The MHSB switch has a hysteresis of 30 seconds to prevent switching on short alarm transients.
The tributary switch and the RF switch are both a 19-inch rack-mount 1U high chassis. The MHSB switch
option is available for all Aprisa XE frequency bands.

Slave Tributary Switches
Each tributary switch protects up to eight ports. Up to three slave tributary switches may be added to a
MHSB terminal to protect up to 32 ports. Each slave tributary switch is interconnected by means of the
slave tributary switch ports on the RF switch, as shown below.
Note: A tributary switch that is operating as a slave (rather than a master) has a RJ-45 V.24 loopback
connector plugged into the console port. If the connector is missing, contact Customer Support.
Alternatively, you can make this connector. Follow the standard pinouts for a V.24 RJ-45 connection (see
‘QV24 Interface connections’ on page 273).

MHSB Cabling
The two radios are interconnected as follows:
CAUTION: Do not connect Transmit to Receive or Receive to Transmit as this may damage the radio or the
MHSB switch.
Cables supplied with MHSB
The following cables are supplied with a MHSB terminal:
Ethernet interface: RJ-45 ports standard TIA-568A patch cables .
Alarm interface: RJ-45 ports standard TIA-568A patch cables.
RF ports: two QMA male patch cables are supplied.
MHSB Power Supply
See ‘DC Power Supply’ on page 37 and ‘AC Power Supply’ on page 40.
Aprisa XE User Manual
186 | Protected Terminals
Configuring the Radios for Protected Mode
The MHSB switch does not require any special software. However, the radios connected to the MHSB
switch must be configured to work with the MHSB switch. This sets the alarm outputs and inputs to
function in MHSB mode.
You must configure the interfaces of both radios connected to the MHSB switch identically. To perform
this, you can either connect directly to the radio or use the test mode of the MHSB switch.
MHSB Terminal IP Addresses
Before configuring the link, you must ensure that the two independent links have correctly configured IP
address details.
All four radios in the protected link must be on the same subnet.
Example of MHSB IP addressing
Aprisa XE User Manual
Protected Terminals | 187
Mounting the MHSB Radios and Switches
Once the IP addresses are correctly configured, it is important to connect the A and B radios' Ethernet and
Alarm ports correctly. In general, mount radio A above the MHSB switch and radio B below the MHSB
switch:
There is an Ethernet connection between any of the four Ethernet ports on each radio and the Ethernet
port on the Tributary switch. There is also a connection between radio A and radio B, which ensures
Ethernet traffic is maintained if a radio loses power.
The Ethernet port on the protection switch can be connected to an Ethernet hub or switch to allow
multiple connections.
Important: The management Ethernet capacity on each of the four radios in the protected terminal must
be identical for remote communications to work and there should only be one IP connection to the
management network (via the tributary switch Ethernet port).
Aprisa XE User Manual
188 | Protected Terminals
Configuring the Terminals for MHSB
It is recommended that you configure the local and remote A side first, then the local and remote B side.
Both the local A and B radios must be configured identically, and both the remote A and B radios must be
configured identically.
Tip: As illustrated below, you may find it helpful to have two browser sessions running simultaneously.
You can then easily see both the A and B sides of the protected link.
To configure MHSB operation:
1. Select Link > Maintenance > MHSB.
2. Enable MHSB mode.
3. Select whether the radio is A or B.
Ensure that the radio connected to the A side of the protection switch (normally above the MHSB
switch) is set to Radio A and the radio connected to the B side of the protection switch (normally
below the MHSB switch) is set to Radio B.
In the event of a power outage, the radios will switch over to the A side of the protection switch when
the power is restored. The A side is also the default active side.
4. When you have made your changes, click Apply to apply changes or Reset to restore the previous
configuration.
5. Repeat steps 2 to 4 for the other side of the protected link.

Clearing MHSB Alarms
If a switchover event occurs, the OK LED on the front panel and on the Terminal status and menu bar in
SuperVisor changes to amber.
1. Select Clear Switched Alarm from the MHSB Command drop-down list.
2. Click Apply to apply changes or Reset to reset the page.
Note: When MHSB mode is enabled, external alarm input 2 is used by the protection system to carry
alarms from the protection switch to the radio. In MHSB mode, therefore, only external alarm input 1 is
available for user alarms.

Hitless Space Diversity (HSD)
HSD provides hitless RF receive path protection and hot standby transmitter redundancy. It is typically
deployed for paths where high path availability is required.
An Aprisa XE hitless space diversity terminal comprises two radio terminals, radio A and radio B.
Radio A is the primary radio which is fitted with the interface cards and connects to antenna A.
Antenna A always carries the transmitted signal and the received signal for Radio A.
Radio B is the secondary radio the receiver of which connects to antenna B. The transmitter in this radio is
the standby transmitter.
In the event of a radio A active transmitter failure, radio B transmitter becomes active.
Antenna B only carries the received signal for Radio B. This antenna is physically separated on the tower
by a pre-determined distance from Antenna A.
As both radios have a receive path, traffic from the path with the best received bit error rate is routed to
the customer interfaces in radio A.
In an HSD terminal, a HSD Protection Switch Card (PSC) is always fitted in slot H in Radio A and a HSD
Protection Interface Card (PIC) is always fitted in slot H in Radio B. The PSC card has a card front switch
which controls the hardware setting of the HSD system Active Radio (Auto Select, Radio A or Radio B).
Customer interfaces are provided on radio A only in interface slots A to G. Interface connections to
Ethernet and the external alarm inputs and outputs are also provided on radio A only.

HSD Terminal Cabling
The two HSD radios are interconnected as follows:
Cables Supplied with HSD Terminal
The following cables are supplied with a HSD terminal:
RF cable
A 110 mm QMA female to QMA female low loss RF cable is required to interconnect between the TX ports
of both radio A and radio B. This cable carries the radio B transmitter output to the radio A transmitter
switch.
Ethernet Cable
A 200 mm RJ45 to RJ45 Ethernet cable between the Ethernet ports of radio A and radio B. This cable
carries management IP traffic between radio A and radio B.
Traffic Cable
A 200 mm RJ45 to RJ45 Ethernet cable between the PSC and PIC. This cable carries all user traffic
between Radio A and Radio B.
Aprisa XE User Manual
192 | Protected Terminals
HSD Terminal IP Addresses
Each radio in the HSD link is assigned a unique IP address. All four radios in the HSD link must be on the
same subnet.
The IP address of the four terminals can only be changed by logging into the relevant radio A or radio B.
When the IP addresses have been setup, an ethernet connection to any of the four radios can access all
four radios in the HSD link. The usual ethernet connection is to the near end Radio A (see ‘IP Addressing of
Terminals’ on page 53).
Example of IP addressing
Aprisa XE User Manual
Protected Terminals | 193
Configuring HSD Terminals
To simplify the management and configuration of the HSD terminals, SuperVisor provides four windows
which display the parameters for all four radios, the local and remote, radios A and B. The HSD System
menu item displays the four windows.
When a parameter is changed in the four window mode, the relevant parameter is automatically changed
to the same setting on the corresponding radio e.g. if a radio A modulation type is changed, the radio B
modulation type is also changed to the same setting.
The Local and Remote menus continue to display the parameters for the local and remote radios for the
near end terminal logged into.
The majority of SuperVisor HSD System pages contain the same parameters and controls as the standard
1+0 XE terminal. The main exceptions are the HSD Control page and the HSD Performance Summary page.
Aprisa XE User Manual
194 | Protected Terminals
HSD Active Radio Control
The HSD system ‘Active Radio’ control determines if the selection of Radio A or Radio B is automatic or
manual. This controls both the radio transmitters and receivers.
The Active Radio can be set with the hardware switch on the PSC card front or with the SuperVisor
software control. The last change of hardware / software control determines the state of the HSD system.
The SuperVisor software control will always reflect the state of the HSD system.
After terminal startup or reboot, the state of the PSC mode switch determines the setting used by the
system and the SuperVisor software control is set to reflect the state of the HSD system.
The PSC card has two card front LEDs which indicate the status of the HSD system:

12. In-Service Commissioning
Before You Start
When you have finished installing the hardware, RF and the traffic interface cabling, the system is ready
to be commissioned. Commissioning the terminal is a simple process and consists of:
1. Powering up the terminals
2. Configuring both the local and remote terminals using SuperVisor
3. Aligning the antennas
4. Synchronizing the terminals
5. Testing the link is operating correctly. As a minimum, conduct the suggested tests to ensure correct
operation. More extensive testing may be required to satisfy the end client or regulatory body
requirements.
6. Connecting up the client or user interfaces
What You Will Need
Appropriately qualified commissioning staff at both ends of the link.
Safety equipment appropriate for the antenna location at both ends of the link.
Communication equipment, that is, mobile phones or two-way radios.
SuperVisor software running on an appropriate laptop, computer, or workstation at one end of the
link.
Tools to facilitate loosening and re-tightening the antenna pan and tilt adjusters.
Predicted receiver input levels and fade margin figures from the radio link budget (You can use
Surveyor (see ‘Path planning’ on page 23) to calculate the RSSI, fade margin, and availability).
Aprisa XE User Manual
198 | In-Service Commissioning
Applying Power to the Terminals
WARNING:
Before applying power to a terminal, ensure you have connected the safety
earth and antenna cable.
Apply power to the terminals at each end of the link.
When power is first applied, all the front panel LEDs will illuminate red for several seconds as the system
initializes.
After the system is initialized, the OK LED on the front panel should illuminate green and if the terminals
are correctly configured, the TX and RX LED should also be illuminated green.
If the RX LED is:
Red
the antennas are may be significantly mis-aligned with no signal being
received
Amber
the antennas may be roughly aligned with some signal being received
Green
the antennas are well-aligned and adequate signal is being received to create
a reliable path
If the TX LED is:
Red
the transmitter is faulty
Amber
there is a fault in the antenna connection or feeder cable
Green
the transmitter is working normally
Review the Link Configurations Using SuperVisor
1. Connect a PC, with SuperVisor installed, to both terminals in the link.
2. Log into the link.
3. Select Link > Summary and confirm the following basic information:
Terminal IP address(es)
Terminal TX and RX frequencies
RSSI (dBm)
TX power (dBm)
SNR (dBm)
Note: If the terminals have not already been configured, refer to ‘Configuring the terminal’ on page 69,
‘Configuring the traffic interfaces’ on page 91, and ‘Configuring the traffic cross connections’ on page
145.

Antenna Alignment
For any point-to-point link, it is important to correctly align the antennas to maximize the signal strength
at both ends of the link. Each antenna must be pointing directly at the corresponding antenna at the
remote site, and they must both be on the same polarization. The antennas are aligned visually, and then
small adjustments are made while the link is operating to maximize the received signal.
Directional antennas have a radiation pattern that is most sensitive in front of the antenna, in line with
the main lobe of the radiation pattern. There are several other lobes (side lobes) that are not as sensitive
as the main lobe in front of the antenna.
For the link to operate reliably, it is important that the main lobes of both antennas are aligned. If any of
the side lobes are aligned to the opposite antenna, the received signal strength of both terminals will be
lower, which could result in fading. If in doubt, check the radiation patterns of the antennas you are
using.
Checking the Antenna Polarization
Check that the polarization of the antennas at each end of the link is the same.
Antenna polarization of grid antennas are normally indicated by an arrow or with ‘H’ and ‘V’ markers
(indicating horizontal and vertical).
On Yagi antennas, ensure the orientation of the elements are the same at each end of the link.
Transmit frequency and power, and antenna polarization would normally be defined by a regulatory body,
and typically licensed to a particular user. Refer to your license details when setting the antenna
polarization.

200 | In-Service Commissioning
Visually Aligning Antennas
1. Stand behind the antenna, and move it from side to side until it is pointing directly at the antenna at
the remote site. The remote antenna may be made more visible by using a mirror, strobe light, or
flag.
If the remote end of the link is not visible (due to smoke, haze, or local clutter, etc), align the
antenna by using a magnetic compass. Calculate the bearing using a scale map of the link path.
When setting the antenna on the desired bearing ensure that you use the appropriate true-north to
magnetic-north offset. Also ensure that the compass reading is not affected by standing too close to
metallic objects.
2. Once the antenna is pointing at the remote antenna, tighten the nuts on the U-bolt or antenna clamp
just enough to hold it in position. Leave the nuts loose enough so that small adjustments can still be
made. Check that the antenna is still pointing in the correct direction.
3. Move the antenna up or down until it is pointing directly at the remote site.
4. Tighten the elevation and azimuth adjustment clamps.
5. Mark the position of the antenna clamps so that the antenna can be returned to this rough aim point
easily when accurately aligning the antennas.
6. Repeat steps 1-5 at the opposite site.
Note: Low gain antennas need less adjustment in elevation as they are simply aimed at the horizon. They
should always be panned horizontally to find the peak signal.
Aprisa XE User Manual
In-Service Commissioning | 201
Accurately Aligning the Antennas
Once the antennas are visually aligned, accurately align both antennas by carefully making small
adjustments while monitoring the RSSI. This will give the best possible link performance.
Note: Remember that it is important to align the main radiation lobes of the two antennas to each other,
not any side lobes. It may be easier to perform this procedure if you can communicate with someone at
the remote site by telephone, mobile, or two-way radio.
1. Connect a laptop PC running SuperVisor software and power up the terminals at both ends of the link.
Select Link > Performance > Summary so that you can see the RSSI indication for the local terminal.
Alternatively, use the RSSI test point on the front panel together with a multimeter (see ‘Measuring
the RSSI’ on page 202).
2. Move the antenna through a complete sweep horizontally (known as a 'pan') either side of the point
established in the visual alignment process above. Note down the RSSI reading for all the peaks in RSSI
that you discover in the pan.
3. Move the antenna to the position corresponding to the maximum RSSI value obtained during the pan.
Move the antenna horizontally slightly to each side of this maximum to find the two points where the
RSSI drops slightly.
4. Move the antenna halfway between these two points and tighten the clamp.
5. If the antenna has an elevation adjustment, move the antenna through a complete sweep (known as a
'tilt') vertically either side of the point established in the visual alignment process above. Note down
the RSSI reading for all the peaks in RSSI that you discover in the tilt.
6. Move the antenna to the position corresponding to the maximum RSSI value obtained during the tilt.
Move the antenna slightly up and then down from the maximum to find the two points where the RSSI
drops slightly.
7. Move the antenna halfway between these two points and tighten the clamp.
8. Recheck the pan (steps 2-4) and tighten all the clamps firmly.
9. Perform steps 1-8 at the remote site.

202 | In-Service Commissioning
Measuring the RSSI
Measure the RSSI value with a multimeter connected to the RSSI test port on the front of the terminal (see
‘Front panel connections and indicators’ on page 31).
1. Insert the positive probe of the multimeter into the RSSI test port, and clip the negative probe to the
chassis of the terminal (earth).
2. Pan and tilt the antenna until you get the highest VDC reading. The values shown in the table below
relate the measured VDC to the actual received signal level in dBm regardless of bandwidth and
frequency.

Checking Performance
The amount of testing performed on the completed installation will depend on circumstances. Some
customers may need to prove to a local licensing regulatory body that the link complies with the license
provisions. This may require special telecommunications test equipment to complete these tests. Most
customers simply want to confirm that their data traffic is successfully passing over the link, or that the
customer interfaces comply with known quality standard.
However, the most important performance verification checks are:
Receive input level
Fade margin
Long-term BER
Checking the Receive Input Level
The received signal strength at the local terminal is affected by many components in the system and has a
direct relationship with the resulting performance of the link. A link operating with a lower than expected
signal strength is more likely to suffer from degraded performance during fading conditions. The receive
input level of a link is normally symmetrical (that is, similar at both ends).
1. Compare the final RSSI figure obtained after antenna alignment with that calculated for the link.
2. If the RSSI figure is in excess of 3 dB down on the predicted level, recheck and correct problems using
the table below and then recheck the RSSI. Alternatively, recheck the link budget calculations.
Possible cause
Terminal(s)
Is the terminal operating on the correct frequency?
Local & remote
Is the remote terminal transmit power correct?
Remote
Are all the coaxial connectors tight?
Local & remote
Is the antenna the correct type, that is, gain and frequency of operation?
Local & remote
Is the antenna polarized?
Local & remote
Is the antenna aligned?
Local & remote
Is the path between the terminals obstructed?
Note: If following the above steps does not resolve the situation, contact Customer Support for
assistance.
3. Record the RSSI figure on the commissioning form.
4. Repeat steps 1 to 2 for the other end of the link.

The fade margin is affected by many components in the system and is closely related to the received
signal strength. A link operating with a lower than expected fade margin is more likely to suffer from
degraded performance during fading conditions. A reduced fade margin can be due to operating the link
too close to the noise floor, or the presence of external interference. The fade margin of a link can be
asymmetrical (that is, different at each end).
Possible causes of low fade margin are as follows:
Problem
Terminal
Low receive signal strength (see above table)
Local and Remote
Interfering signals on the same, or very close to, the frequency of the
local terminal receiver.
Local
Intermodulation products that land on the same or very close to the
frequency of the local terminal receiver.
Local or Remote
Operating near the local receiver noise floor
Local
To check the fade margin:
1. Confirm (and correct if necessary) the receive input level (see the previous test).
Note: If the receive input level is lower than expected, the fade margin may also be low.
2. Select Link > Performance > Summary and check the current BER of the link in its normal condition is
better than 10-6 (If necessary, clear out any extraneous errors by clicking Reset Counters).
3. Check the signal to noise (S/N) indication on the Link > Performance > Summary page. This shows the
quality of the signal as it is being processed in the modem. It should typically be better than 30 dB. If
it is less than 25 dB, it means that either the RSSI is very low or in-band interference is degrading the
S/N performance.
4. Temporarily reduce the remote site's transmit power using either an external attenuator or SuperVisor
(Remote > Terminal > Basic).
Note: Ideally, the transmit power of the remote site should be reduced by up to 20 dB, which will
require the use of an external 50 ohm coaxial attenuator capable of handling the transmit power
involved. In the absence of an attenuator, reduce the transmit power using SuperVisor.
5. Check and note the current BER of the link in its now faded condition (Again, if necessary, clear out
any extraneous errors (introduced by the power reduction step above) by clicking Reset Counters).
6. Compare the unfaded and faded BER performance of the link (steps 2 and 4). Continue to reduce the
remote transmit power until either the BER drops to 10 -6 or the remote transmitter power has been
reduced by 20 dB.
Note: The fade margin of the link is expressed as a number (of dB) that the link can be faded
(transmitter power reduced) without reducing the BER below operating specifications (1 * 10-6 BER). A
20 dB fade margin is adequate for most links.

In-Service Commissioning | 205
7. Record the fade margin and SNR results on the commissioning form.
Note: If the transmit power is reduced using SuperVisor rather than an external attenuator, the fade
margin should be recorded as ‘Greater than x dB’ (where x = the power reduction).
8. Restore the remote terminal transmit power to normal.
9. Repeat steps 1 to 7 for the other end of the link.
Note: If following all the guidelines above does not resolve the situation, contact Customer Support
for assistance.
Checking the Long-Term BER
The BER test is a measure of the stability of the complete link. The BER results of a link can be
asymmetrical (that is, different at each end).
1. Select Link > Performance > Summary and check the current BER and error counters of the link. If
necessary, clear out any extraneous errors by selecting Reset Counters.
2. Wait 15 minutes, and check the BER display and error counters again. If there are a small number of
errors and the BER is still better than 1 x 10-9, continue the test for 24 hours. If there are a significant
number of errors, rectify the cause before completing the 24 hour test.
Note: It is normal to conduct the BER test in both directions at the same time, and it is important that
no further work be carried out on the equipment (including the antenna) during this period.
3. The BER after the 24 hour test should typically be better than 1 x 10-8.
4. Record the BER results on the commissioning form.
Bit Error Rate Tests
A Bit Error Rate (BER) test can be conducted on the bench, (see ‘Bench Setup’ on page 43).
Attach the BER tester to the interface port(s) of one terminal, and either another BER tester or a loopback
plug to the corresponding interface port of the other terminal.
This BER test can be carried out over the Ethernet, E1 / T1, V.24 or HSS interfaces. It will test the link
quality with regard to user payload data.
CAUTION: Do not apply signals greater than -20 dBm to the antenna as they can damage the receiver. In a
bench setup, there must be 60 - 80 dB at up to 2 GHz of 50 ohm coaxial attenuation (capable of handling
the transmit power) between the terminals’ antenna connectors.

Checking the Link Performance
For a graphical indication of the link performance, you can use the constellation analyzer.
The 'dots' are a graphical indication of the quality of the demodulated signal. Small dots that are close
together indicate a good signal. If the dots become spaced further apart, this indicates that the signal
quality is degrading. This signal quality degradation can be caused by low Rx signal level due to, for
example:
external interference
failure of any of the following: modem, receiver, far end transmitter, an antenna (either end), a
feeder or connector (for example, due to water damage)
path issues such as multipath fading or obstructions
To check the performance of the link using the constellation analyzer:
1. Select Link or Local or Remote > Performance > Constellation.
2. Click Start to start the constellation analyzer.
While the constellation analyzer is running, the terminal will temporarily stop collecting error
performance statistics. If you want to run the constellation analyzer anyway, click OK when you see
this warning message:
3. Click Stop to stop the constellation analyzer.
The terminal automatically resumes collecting error performance statistics.

Terminal Upgrades
You can upgrade all software for both terminals remotely (through a management network), which
eliminates the need to physically visit either end of the link.
A terminal is upgraded by accessing a running TFTP server (see ‘TFTP Upgrade Process’ on page 221). All
the required files are uploaded from the TFTP server into the terminal and then activated following a
terminal reboot.
System files can be manually uploaded (see ‘Uploading System Files’ on page 226‘).
Inventory File
Software release 8.2.10 and all future software releases, contains an inventory file (similar to a manifest
file) which is used to validate the software files in the terminal.
To view the Software Status of the terminal:
Select Link, Local or Remote > Summary
Software status
Function
Standard Software
Release
The software status indicates ‘Standard Software Release’ if the
following system software files have not been changed since the last
TFTP Upgrade.
Kernel image file
Software image file
Firmware image files
Configuration files
Modified Software
Release
The software status indicates ‘Modified Software Release’ if the system
software files have been changed since the last TFTP Upgrade.
This could be caused by:
an image file which has been uploaded to the terminal since the
last TFTP upgrade which is not part of that upgrade.
an image file which was part of the last TFTP upgrade but was
subsequently deleted.
Upgrade Prerequisites
To minimize disruption of link traffic and prevent your terminals from being rendered inoperative, please
follow the procedures described in this section together with any additional information or instructions
supplied with the upgrade package.
Before upgrading the terminal, ensure that you have saved the configuration file (see ‘Saving the
terminal's configuration’ on page 89) as well as the cross connection configuration (see ‘Saving cross
connection configurations’ on page 155).
The Remote terminal upgrade process will be faster if the bandwidth allocated to the management
ethernet capacity is maximized.
The terminal software must be identical at both ends of the link.
At the end of the terminal upgrade process, the versions of image files (kernel software, and firmware)
that were in use before the upgrade are still in the terminal. You can restore them, if required, by editing
the image tables and reactivating the old files (see ‘Changing the Status of an Image ’ on page 232).
IMPORTANT NOTE: Ensure you are logged into the Near end terminal as Admin before you start an
upgrade.
Aprisa XE User Manual

Software Upgrade Process
Unzip and save the following folders to your hard drive:
8.6.77 Software
tftpd32.exe
The following steps are required for the software upgrade process:
1. Identify the correct TFTP upgrade type (see ‘Identifying the Correct TFTP Upgrade Type’ on page
217).
2. If the terminals are operating software prior to 8.3.40:
Upload the Root File System (see ‘Uploading the Root File System’ on page 216)
Upload the Motherboard Images (see ‘Uploading the Motherboard Images’ on page 216).
Reboot the terminal.
3. Go through the steps of the TFTP upgrade process (see ‘TFTP Upgrade Process’ on page 221).
4. Upgrade for new FXO/FXS and modem images
5. Reboot the terminal.
6. Clear the Java and web browser caches (see ‘Step 7: Clear the Java and web browser caches’ on
page 223).
If the TFTP upload process fails, an ‘Upload Fail’ alarm is raised. If the TFTP upload process fails due to a
power failure, the alarm is raised upon power recovery.

Identifying the Correct TFTP Upgrade Type
The correct TFTP upgrade type will depend on both the Bootloader Version and the Software Version
Type.
Aprisa XE terminals running the older bootloader software (bootloader version 0) have a limitation on the
number of software images that can be loaded simultaneously into a terminal.
Identifying the Bootloader Version
Determine which bootloader version your terminal is running by using the SuperVisor menu item
Maintenance > Support Summary and look for the ‘Bootloader Version’ number:
(1)
If your terminal is running bootloader version 1 or greater, use the TFTP full upgrade process.
(2)
If your terminal is running bootloader version 0 and running a software version prior to 7.0.6,
use the TFTP partial upgrade process.
(3)
If your terminal is running bootloader version 0 and running a software version 7.0.6 or later,
use the TFTP standard upgrade process.
(4)
HSD terminals cannot run with bootloader version 0.

Uploading System Files
System files e.g. configuration files, kernel image files, software image files and firmware image files can
be uploaded manually.
Note: You should only upgrade components that need changing. It is not always necessary, for instance, to
replace kernel or software files when upgrading a single firmware file. If interdependency exists between
file types, this will be made clear in the documentation that accompanied the update package.
Configuration Files
Configuration files (.cfg) are compressed archives containing a script to instruct the terminal on how to
handle the other files in the archive.
Uploading of configuration files can only be performed to the Local Terminal (not via the link to the
Remote Terminal).
RF synthesizer configuration files
The RF synthesizer configuration archive contains files that provide values for the transmitter and receiver
synthesizers to operate across the supported frequency bands.
Synthesizer configuration filenames have the following format:
XE_(frequency bands)_synth.cfg
e.g. XE_300_400_synth.cfg
Modem configuration files
The Modem configuration archive contains files that provide values for the Modem to operate at the
various supported channel sizes and modulation types.
Modem configuration filenames have the following format:
modem_(version number).cfg
e.g. modem_8_3_1.cfg (ETSI variants)
Cross-connect configuration files
The Cross-connect configuration archive contains the Cross Connections application program that can be
launched from within SuperVisor.
Cross-connect configuration filenames have the following format:
C-crossconnect_(version number).cfg
e.g. C-crossconnect_8_6_7.cfg
Aprisa XE User Manual

Image Files
Image files (.img) are loaded into the terminal and either contains code that is executed by the system
processor, or contain instructions to configure the various programmable logic elements. The image file
types that can be uploaded are:
Kernel image files
Software image files
Firmware image files
Note: The Bootloader image file C-CC-B-(version number).srec and Flash File System image file C-CC-F(version number).img can only be changed in the factory.
Uploading of image files can only be performed to the local terminal (not via the link to the remote
terminal).
To upload and activate an image file:
1. Upload the required image file.
If the Upload Status page show ‘executing’, then ‘writing to flash’, then ‘Succeeded’, then the file has
been written into the image table correctly.
If the Upload Status is ‘Failed’, there may not be enough free space in the image table to write the
file. Inactive images can be deleted (and the terminal rebooted) to free up space for the new image
(see ‘Changing the Status of an Image File’ on page 232).
2. Set the status of the image to ‘activate’ (see ‘Changing the Status of an Image ’ on page 232).
This actually sets the status to ‘Selected’ until after a terminal reboot.
3. Reboot the terminal using a ‘Hard Reboot’ (see ‘Rebooting the Terminal’ on page 233).
This activates the selected image. The image table status will now show ‘Active’.
The previous image file status will now show as ‘Inactive’.

Installing Interface Cards
CAUTION: You must power down the terminal before removing or installing interface cards.
Interface cards are initially installed in the factory to the customers’ requirements however, during the
life of the product, additional interface cards may need to be installed.
Unless the terminals are protected (see ‘Protected terminals’ on page 197), installing new interface cards
involves a substantial interruption of traffic across the link. Staff performing this task must have the
appropriate level of education and experience; it should not be attempted by inexperienced personnel.
To install an interface card:
1. Switch off the power to the terminal.
2. Prepare the terminal for new interface cards (see ‘Preparing the Terminal for New Interface Cards’ on
page 236).
3. Install the interface card (see ‘Installing an Interface Card’ on page 238).

Preparing the Terminal for New Interface Cards
To prepare the terminal for a new interface card:
1. Remove the terminal from service by first switching off the terminal power. For an AC powered
terminal, remove the AC power connector. For a DC powered terminal, switch off the DC circuit
breaker or supply fuse.
2. Remove all other cables from the terminal, marking their locations first, if necessary, to aid later
restoration. The safety earth connection must be the last cable removed.
3. Ensure you have unobstructed access to the top and front of the terminal. Remove the terminal from
the equipment rack, if required.
4. Remove the top cover of the terminal by removing two socket screws from the rear.
Note: The top cover slides back towards the rear of the chassis.
5. Remove the front fascia by removing the four front panel socket screws.
Note: The front fascia first hinges out to clear the antenna connector and earth stud, and is then
removed by unclipping from the chassis and sliding downwards. See illustration below.

Loopbacks
Loopbacks are used as a tool for testing or as part of the commissioning process and will affect customer
traffic across the link.
The terminal supports three types of loopbacks:
RF radio loopback
Interface loopbacks, set at the interface ports
Timeslot loopbacks
RF Radio Loopback
The RF radio loopback provides a loopback connection between the radio TX and radio RX. Each terminal
is looped back independently.
All traffic entering the transmit stage of the transceiver is transmitted on the RF link but is also looped
back to the receiver section of the transceiver. This loopback will affect all traffic through the terminal.
When the RF loopback is activated, both the radio RX and TX LEDs will flash.
An RF loopback will automatically deactivate after the period set (in seconds) in the RF Loopback Timeout
field. The default entry is 3600 seconds (60 minutes).
When an RF loopback is activated, the ethernet path is disabled to prevent ethernet loopbacks.
An RF loopback is deactivated if the terminal is rebooted.
To activate or deactivate the RF loopback:
Select Link or Local or Remote > Maintenance > Loopbacks.
To activate the RF loopback, tick the RF Loopback checkbox. Untick the checkbox to deactivate it.
Click Apply to apply changes or Reset to restore the previous configuration.

Interface Loopbacks
The interface loopback provides a loopback connection for the customer-connected equipment.
These loopbacks are applied on a port-by-port basis and can only be enabled on active ports i.e. the port
has to be activated by assigning traffic to it by the Cross Connections application.
These are two types of interface loopbacks:
Line Facing – port traffic from the customer is transmitted over the RF link but is also looped back to the
customer
Radio Facing – traffic received from the RF link is passed to the customer port but is also looped back to
be transmitted over the RF link.

transmitter synthesizer
Modem Lock
The terminal modem is not synchronized with the modem at the other end
of the link
TX Temp Shutdown
The transmitter power amplifier temperature is greater than 75°C. The
transmitter has shut down to prevent damage.
TX Temp Warning
The transmitter power amplifier temperature is greater than 70°C. The
transmitter will continue to operate in this condition, but if the power
amplifier temperature increases above 75°C, a major alarm condition is
set and the transmitter will shut down to prevent further damage.
TX AGC Voltage
The transmitter power amplifier automatic gain control is out of limits for
normal operation
TX Reverse Power
There is excessive reflected power at the transmitter port of the terminal,
indicating a low return loss in the path between transmitter port and the
antenna.
TX Return Loss

E1 / T1 Alarm Conditions
The QJET interface yellow LED indicates:
Loss of signal (LOS)
A loss of signal alarm occurs when there is no valid G.703 signal at the E1 / T1 interface RX input from
the downstream system.
This alarm masks the LOF and AIS received alarms.
Loss Of Frame alignment (LOF)
A loss of frame alignment alarm occurs when the E1 / T1 interface RX input receives a valid G.703
signal (code and frequency) but does not receive a valid G.704 signal i.e. no frame alignment word,
from the downstream system (in framed E1 / T1 modes only) (red alarm in framed T1 modes).
This alarm masks the AIS received alarm.
Alarm Indication Signal (AIS)
An AIS received alarm occurs when AIS is received from the downstream system.
An E1 / T1 interface will output AIS to the downstream system if the normal upstream traffic signal is
not available e.g. loss of modem synchronization, loss of RF signal across the link (blue alarm in
framed T1 modes).
Remote Alarm Indicator (RAI)
A remote alarm indicator occurs when RAI is received from the downstream system when it has an
active LOS or LOF alarm (TS0 NFAS bit 3 in framed E1 modes and yellow alarm in framed T1 modes).
TS16 Loss of signal (TS16LOS)
A TS16 loss of signal alarm occurs when there is no valid TS16 signal at the E1 interface RX input from
the downstream system (in E1 PCM 30 modes only).
TS16 Remote Multi-frame Alarm Indicator (RMAI)
A remote multiframe alarm indicator occurs when RMAI is received from the downstream system when
it has an active TS16LOS alarm (TS16 F0 bit 6 in E1 PCM 30 modes only).
TS16 Alarm Indication Signal (TS16AIS)
A TS16 Alarm Indication Signal alarm occurs when AIS is received from the downstream system in TS16.
An E1 interface will output the TS16 AIS signal to the downstream system if the normal TS16 multiframe signal is not available (in E1 PCM 30 modes only).

System Log
SuperVisor automatically keeps a log, known as 'syslog', which captures all alarms, errors and events for
each terminal.
You can specify that the ‘syslog’ is saved to a particular file (see ‘Setting up for Remote Logging’ on page
255). You can then email this file to customer service, if requested, to enable them to fault-find more
accurately.
Checking the Syslog
To view the Syslog:
1. Select Local > Performance > Logging > Syslog.
This opens a new window:

254 | Troubleshooting
2. The system log is quite hard to decipher in Internet Explorer. If you're using Internet Explorer, select
View > Source, which opens the file in a more legible layout in Notepad. Save or print this file, as
required.
3. If you want to save the system log, you can save it from within Notepad (or Internet Explorer). Select
File > Save As. Navigate to where you want to save the file. Enter a meaningful filename and select
'Text File' from the Save As Type drop-down list. Click Save.
You can specify that this file is automatically saved to a computer (see ‘Setting up for Remote Logging’ on
page 255).

Setting up for Remote Logging
Note: When setting up to save the system log to a specific computer, be aware that the file is constantly
updated and may get quite large quite quickly.
To set up a terminal for remote logging:
1. Copy the TFTP server application (tftpd32.exe, which is located in the TFTPD directory) from the
terminal product CD into a suitable directory on the PC (for example, C:\Program Files\TFTP Server).
2. Create another directory where you want the system logs to be saved for example;
C:\Aprisa XE Syslog
3. Double-click tftpd32.exe.
4. Click Settings and make sure that both ‘Syslog Server’ and ‘Save syslog message’ boxes are ticked.
5. Click Browse and select a directory where you want the Syslog file to be saved (created in step 2).
6. Click OK to close the Settings dialog box.

running.
9. In the Remote Syslog Port field, enter 514.
10. Reboot the terminal (Link or Local or Remote > Maintenance > Reboot).
11. Open the directory where the system logs are being saved to. You should see a file called syslog.txt.

19. Product End Of Life
End-of-Life Recycling Programme (WEEE)
The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment.
Under the Directive, used equipment must be marked, collected separately, and disposed of properly.
4RF Limited has implemented an end-of-life recycling programme to manage the reuse, recycling, and
recovery of waste in an environmentally safe manner using processes that comply with the WEEE Directive
(EU Waste Electrical and Electronic Equipment 2002/96/EC).
The WEEE Symbol Explained
This symbol appears on Electrical and Electronic Equipment (EEE) as part of the WEEE (Waste EEE)
directive. It means that the EEE may contain hazardous substances and must not be thrown away with
municipal or other waste.
WEEE Must Be Collected Separately
You must not dispose of electrical and electronic waste with municipal and other waste. You must
separate it from other waste and recycling so that it can be easily collected by the proper regional WEEE
collection system in your area.
YOUR ROLE in the Recovery of WEEE
By separately collecting and properly disposing of WEEE, you are helping to reduce the amount of WEEE
that enters the waste stream.
One of the aims of the WEEE directive is to divert EEE away from landfill and encourage recycling.
Recycling EEE means that valuable resources such as metals and other materials (which require energy to
source and manufacture) are not wasted. Also, the pollution associated with accessing new materials and
manufacturing new products is reduced.
EEE Waste Impacts the Environment and Health
