3. Preparation
Path Planning
Proper path planning is essential. When considering the components of your radio system, think about:
antenna selection and siting coaxial cable selection link budget
You can also use Surveyor to help you with path feasibility planning.
Surveyor is a path propagation calculator developed by 4RF to assist path planners quickly and efficiently
verify the viability of point-to-point transmission links deploying the Aprisa microwave radio systems.
The software program calculates the anticipated link performance for the transmission system elements
you have selected. However, it is not a substitute for in-depth path planning.
You will find Surveyor a valuable addition to your planning toolbox.
A copy of Surveyor is provided on the Aprisa CD supplied with this manual. You can download updates from
www.4rf.com.
Antenna Selection and Siting
Selecting and siting antennas are important considerations in your system design.
There are three main types of directional antenna that are commonly used with the radios parabolic grid,
Yagi and corner reflector antennas.
The antenna that should be used for a particular situation is determined primarily by the frequency of
operation and the gain required to establish a reliable link.
Stacked: about the same as a
parabolic grid antenna

Yagi Antennas
It is possible to increase the gain of a Yagi antenna installation by placing two or more of them in a stack.
The relative position of the antennas is critical.

Corner Reflector Antennas
Antenna Siting
When siting antennas, consider the following points:
A site with a clear line of sight to the remote terminal is needed. Pay particular attention to trees,
buildings, and other obstructions close to the antenna site.
Example of a clear line-of-sight path
Any large flat areas that reflect RF energy along the link path, for instance, water, could cause
multipath fading. If the link path crosses a feature that is likely to cause RF reflections, shield the
antenna from the reflected signals by positioning it on the far side of the roof of the equipment
shelter or other structure.
Example of a mid-path reflection path
The antenna site should be as far as possible from other potential sources of RF interference such as
electrical equipment, power lines and roads.
The antenna site should be as close as possible to the equipment shelter.
Note: Wide angle and zoom photographs taken at the proposed antenna location (looking down the
proposed path), can be useful when considering the best mounting positions.

Effect
Attenuation
Short cables and larger diameter cables have less attenuation
Cost
Smaller diameter cables are cheaper
Ease of installation
Easier with smaller diameter cables or short cables
Coaxial Feeder Cables
To ensure maximum performance, it is recommended that you use good quality low-loss coaxial cable for
all feeder runs. For installations requiring long antenna cable runs, use Andrew Heliax™ or equivalent.
When using large diameter feeders, use a short flexible jumper cable between the feeder and the
terminal to reduce stress on the antenna port connector.
All coaxial cable has loss, that is, the RF energy traveling through it is attenuated. Generally speaking, the
larger the diameter of the cable, the less the loss. When selecting a coaxial cable consider the following:
When running cables:
Run coaxial cable from the installation to the antenna, ensuring you leave enough extra cable at each
end to allow drip loops to be formed.
For 19-inch rack mount installations, cables may be run from the front of the rack directly onto the
antenna port. They may also be run through the back of the rack to the front.
Terminate and earth or ground the cables in accordance with the manufacturers' instructions. Bond
the outer conductor of the coaxial feeder cables to the base of the tower mast.
Link Budget
All of the above factors (and many others not mentioned) combine in any proposed installation to create a
link budget. The link budget predicts how well the radio link will perform after it is installed.
Use the outputs of the link budget during commissioning testing to confirm the link has been installed
correctly, and that it will provide reliable service.

alarm output is < 2 seconds.
Alarm outputs are isolated semiconductor relay type contacts rated 0 to 60 VDC or AC rms with a
maximum current of 100 mA.
Alarm inputs are isolated current detectors with an operating voltage range of 9 to 60 VDC or AC rms
(effective current threshold of 5.0 to 6.5 mA constant current).
The common reference potential for the two external alarm inputs must be applied to pin 3 and the
common reference potential for the four external alarm outputs must be applied to pin 4.
Alarm Circuit Setup
A typical alarm circuit setup is:
An external battery applied to the ‘common alarm inputs reference’ and a normally open relay
contact connected to the alarm input. Closing the contact applies the source to the alarm input
detector which turns the alarm on (setup for ‘alarm on when source on’). See ‘Configuring the
External Alarm Inputs’ on page 81 for the setup options.
An external earth applied to the ‘common alarm outputs reference’ and a ground contact detector
connected to the alarm output. When the alarm is on (active), the external alarm output relay contact
closes (setup for ‘relay closed when alarm on’). See ‘Configuring the External Alarm Outputs’ on page
83 for the setup options.

Power Supplies
US and Canada: Installations should be in accordance with US National Electrical Code ANSI / NFPA 70,
and Canadian Electrical Code, Part 1 C22.1.
DC Power Supply
There are four DC power supply options for the terminal; 12 VDC, 12 VDC Low Power, 24 VDC and 48 VDC.
The DC inputs are polarity critical so the DC voltage must be applied with the correct polarity.
CAUTION: An all-pole switch or DC circuit breaker of the rating shown in the table above must be fitted
between the terminal DC input and the DC power source.
Each terminal or MHSB terminal should have its own separate fuse or DC circuit breaker.
12 VDC / 24 VDC / 48 VDC Power Supply
The power supply DC input is isolated from ground, so the DC power input can be either positive grounded
or negative grounded. The positive or negative terminal should be connected to ground.
12 VDC LP Power Supply
The 12 VDC Low Power is a high efficiency power supply for low power consumption applications up to a
maximum of 53 watts input power (see ‘Power Consumption’ on page 312).
The DC input on this power supply is not isolated from ground as the negative input is internally connected
to ground via the Aprisa XE chassis. The DC power input for this power supply must be a positive 12 V
supply with the negative grounded.

12 VDC Cable
The 12 VDC power supply is supplied with a 3 metre red/black cable of two pairs of 2.3 mm2 (72 strands of
0.2 mm2) making a total of 4.6 mm2 per connection. This increase in wire size is to carry the increased
current consumption of the 12 VDC supply (max 18 Amps per terminal).
This 3 metre cable is engineered to power a fully loaded terminal from a 12 VDC supply. A longer cable
should not be used as the additional voltage drop could cause the power supply to fail.
If longer cable runs are required between the 12 VDC power supply and the terminal, it is suggested that
high current distribution bus bars are used to feed the rack and the supplied power cable used between
the bus bars and the terminals.

Bench Setup
Before installing the link in the field, it is recommended that you bench-test the link. A suggested setup
for basic bench testing is shown below:
When setting up the equipment for bench testing, note the following:
Earthing—the terminal should be earthed at all times. The terminal earth stud must be connected to a
protection earth.
Attenuators— In a bench setup, there must be 60 - 80 dB at up to 3 GHz of 50 ohm coaxial attenuation
(capable of handling the transmit power of +35dBm) between the terminals’ N type antenna
connectors.
This can be achieved with two fixed attenuators fitted to the antennas 'N' connectors and a variable
attenuator with a ≥ 60 dB range. You can use other attenuator values as long as you consider the
transmit power output level (max +33 dBm) and the receiver signal input (max -20 dBm).
Cables—use double-screened coaxial cable that is suitable for use up to 3 GHz at ≈ 1 metre.
CAUTION: Do not apply signals greater than -20 dBm to the antenna connection as they can damage the
receiver.

Connecting to the Terminal's Ethernet Interface
The main access to a terminal for management is with the ethernet interface using standard IP
networking. There should be only one ethernet connection from the terminal to the management network.
The terminals are pre-configured to use IP addressing in one of the common 'non-routable' IP address
ranges. This means the terminals are usually recognized by your operating system without any
reconfiguration.
However, you should change these default addresses (see ‘Changing the Terminal’s IP Address’ on page
64) to comply with your IP addressing scheme.
In the example below, the active management PC must only have one connection to the link as shown by
path . There should not be any alternate path that the active management PC can use via an alternate
router or alternate LAN that would allow the management traffic to be looped as shown by path .

IP Addressing of Terminals
When logging into a link, it is important to understand the relationship between the Local / Remote and
the Near end / Far end terminals.
The Near end terminal is the terminal that has its ethernet port physically connected to your IP network.
The Far end terminal is the terminal that is at the other end of the link from the Near end terminal and
communicates through the management connection over the radio link to the Near end terminal.
The Local terminal is the terminal that SuperVisor is logged into and is displayed on the left hand side of
the SuperVisor screen. The Local terminal can be the Near end or Far end terminal.
The Remote terminal is the terminal that is at the other end of the link from the Local terminal and is
displayed on the right hand side of the SuperVisor screen.
To prevent confusion when operating SuperVisor, determine the IP address of the Near end terminal and
log into that terminal. This is now the Local terminal.
The distinction is important as:
Some functions can only be carried out on the Local terminal. Having different configurations at each end of the link will disrupt communications between the
terminals. In these circumstances it is important to make changes to the Far end terminal of the link
first. The link is then lost only until the near end configuration is completed and communication
restored.
If the Near end terminal is modified first, the link is lost for much longer as staff will have to either
physically visit the Far end terminal to restore the link, or restore the near end to match the far end,
re-establish the link, then start the process again, this time with the Far end terminal first.

If two fundamental radio parameters (RX and TX frequency or modulation) are changed on the remote
terminal in the same apply action (simultaneously), the first parameter change could break the
communications link to the remote terminal and prevent the other commands from being actioned. There

RX and TX Frequency
The local terminal transmit frequency must match the receive frequency of the remote terminal and the
remote terminal transmit frequency must match the receive frequency of the local terminal.
When setting the RX and TX frequency with SuperVisor, the frequency entered is automatically resolved to
the synthesizer step size for the terminal frequency band e.g. an ETSI 1400 MHz band frequency entry of
1474,010,000 Hz will be changed to 1474,012,500 Hz (see synthesizer step size in the table ‘Frequency
Bands’ on page 287).
The RX and TX frequency entered must be:
Within the frequency band limits of the chosen RF frequency band of the terminal as specified in
‘Frequency Bands’ on page 287. e.g. for an ETSI frequency band of 1400 MHz, the frequency band
limits are 1350 to 1550 MHz.
Within the TX / RX passband of the duplexer fitted in the terminal e.g. for a frequency band of
1400 MHz, the standard duplexer passband is 7 MHz and the TX / RX split is 48 MHz (see Duplexer
(bandpass) ‘Duplexers’ on page 301).
The duplexer passband and center frequencies are written on the duplexer label.
The TX and RX frequencies are validated against the duplexer parameters entered on SuperVisor Link or
Local or Remote > Terminal > Duplexer (see ‘Setting the Duplexer Parameters’ on page 79).
If the TX or RX frequency entered is not valid i.e. outside the operating range of the duplexer, a warning
message will popup. OK accepts the frequency entered and cancel rejects the frequency entered.
Important: Changing the remote terminal RX or TX frequency will disable all management communication
to the remote terminal but by changing the local terminal to match the remote terminal, the radio link
will be restored as will the management communication
BUT if the remote terminal RX or TX frequency is changed to be outside the operating range of the
terminal, changing the local terminal to match the remote terminal will not restore the radio link and all
management communication will be lost.
The remote terminal TX and RX frequencies cannot be changed simultaneously i.e. change one direction
and ‘Apply’ the change and then change the other direction and ‘Apply’ the change.
To change both TX and RX frequencies:
1. Change the remote terminal RX frequency and ‘Apply’ the change. The radio link will fail.
2. Change the local terminal TX frequency to that of the remote RX frequency and ‘Apply’ the change.
The radio link will restore.
3. Change the remote terminal TX frequency and ‘Apply’ the change. The radio link will fail.
4. Change the local terminal RX frequency to that of the remote TX frequency and ‘Apply’ the change.
The radio link will restore.
Transmit power
The transmitter power is the power measured at the duplexer output port.
The transmitter power adjustment range varies depending on the Modulation type and frequency band of
the terminal. For ETSI transmitter power range see ‘Transmitter Power ETSI’ on page 290.

Modem Mute Mode
The Aprisa XE radio always mutes its interface ports when the modem loses lock.
The Modem Mute feature mutes its interface ports when the modem Reed Solomon forward error
correction capability can no longer correct errors.
This can occur when the signal strength of the RF link reduces to within about 2 dB of the theoretical
sensitivity of the radio or when the radio is operating well above the sensitivity threshold but is in an
environment subject to impulse noise interference on the RF path.
When the mute activates;
On the analog cards, Q4EM, DFXS and DFXO, the audio path mutes and the signalling states go
idle.
On the digital cards, QV24 and HSS, it causes an all ones data pattern to be driven on the RXD
output line and handshake lines such as RTS / CTS to their off states while on the QJET card it
forces the ports to an AIS state.
The Modem Mute feature effectively reduces the radio receiver sensitivity by 2 to 3 dB from its published
values but will prevent errors from corrupting the tributary audio circuits.
Modem Mute Time
The Modem Mute Time determines the time the mute will persist after the last uncorrectable block is
received. This can be set from 0 to 10 seconds in 0.1 second steps.
Note: The Modem Mute feature is only available if the radio modem is Rev D or later. If the radio has a
Rev A, Rev B or Rev C modem, the modem mute functionality is not displayed in SuperVisor.

Configuring SNMP Settings
In addition to web-based management (SuperVisor), the terminal can also be managed using the Simple
Network Management Protocol (SNMP). MIB files are supplied, and these can be used by a dedicated SNMP
Manager, such as Castle Rock's SNMPc (www.castlerock.com), to access most of the terminal's configurable
parameters.
However, it is recommended that SNMP is only used for status and alarm monitoring of your entire
network. SuperVisor is the best means to configure individual terminals.
For communication between the SNMP manager and the terminal, Access Controls, Trap Destinations, and
Community strings must be set up as described in the following sections.
A SNMP Access Control is the IP address of the terminal used by an SNMP manager or any other SNMP
device to access the terminal. Entering an IP address of ‘Any’ (not case sensitive) or * will allow any IP
address access to the terminal. A community string is sent with the IP address for security.
Commands are sent from the SNMP manager to the terminal to read or configure parameters of the
terminal e.g. setting of interface parameters.
A SNMP Trap Destination is the IP address of a station running an SNMP manager. A community string is
sent with the IP address for security.
Events are sent from the terminal to the SNMP manager e.g. alarm events.
A SNMP Community String is used to protect against unauthorized access (similar to a password). The
SNMP agent (terminal or SNMP manager) will check the community string before performing the task
requested in the SNMP message . Trap Destinations and Access Controls both use community strings for
protection.
To configure Trap Destinations and Access Controls:
Select Local > Maintenance > SNMP > SNMP Settings
Note: SNMP Settings can only be setup on the local terminal.

Ethernet Switch
In the default mode, the Ethernet switch passes IP packets (up to 1522 bytes) as it receives them.
However, using SuperVisor you can configure VLAN, QoS and port speed settings to improve how IP traffic
is managed.
This is useful for operators who use virtual networks to segment different groups of users or different
types of traffic in their network. These groups can be maintained across the radio link thus ensuring users
in one virtual network cannot access data in other virtual networks.
The switch also has a high-speed address lookup engine, supporting up to 2048 preferential MAC addresses
as well as automatic learning and aging. Traffic is filtered through this table and only traffic destined for
the remote end is sent across the link improving bandwidth efficiency.
Note: You need ‘modify’ or ‘admin’ privileges to configure the Ethernet for VLAN and Quality of Service
(QoS).
VLAN tagging
By default, all user and management traffic is allocated the same VLAN across the link.
Alternatively, you can assign each of the four Ethernet ports to a VLAN. Each VLAN can be configured to
carry user traffic, or user traffic and radio management traffic. The VLAN tagging conforms to IEEE
802.1Q standard.

Aprisa XE User Manual
Specifying the VLAN ID for the Ethernet Ports
Each Ethernet port can be configured with one of five VLAN IDs. You can configure each of the physical
ports, numbered 1 to 4 with a VLAN ID (numbered User1 to User4 and User+Mgmt).
These VLAN IDs are applied at the ingress port and only used internally across the link. The VLAN ID is
removed when traffic exits the switch at the egress port. Data entering the Ethernet switch on ports 1 to 4
or the internal management port can only exit on ports that are associated with the same VLAN ID as the
ingress port.
For example, the physical RJ-45 port 1 may be on VLAN 3 at the local end, but at the remote end, the
physical RJ-45 port 4 may be associated with VLAN 3. Traffic entering the local end on port 1 will exit the
remote end on port 4.
To allow the radio link to transport traffic using existing VLAN ID information, the radio adds an extra
VLAN ID over the top of an existing VLAN ID (double-tagging). This extra VLAN ID is added at the ingress
port and removed at the egress port. This adds 4 bytes to the packet and the maximum packet size
supported by the radio is 1526 bytes.
Note 1: Tagged flows can only have one port per VLAN ID on each terminal.
Note 2: The ethernet switch only supports packets up to 1522 bytes in size at the ingress port.
1. Select Link or Local or Remote > Interface > Ethernet Settings.
Note: Always configure the remote terminal before the local terminal
2. In the Quick Links box at the bottom of the page, select the port you want to configure:
3. The Ethernet Port Settings page appears for the port you selected:
4. From the Ethernet Group drop-down list, select the VLAN group to which you want this port to belong.
Important: To access radio management traffic, you need to allocate one of the VLANs to ‘User and
Management’. It is strongly recommended that you indicate which port or group of ports is associated
to the management traffic first.
5. Click Apply.
6. Repeat steps 1-4 for the Ethernet switch in the other terminal in the link.

Aprisa XE User Manual
Quality of Service
Quality of Service (QoS) enables network operators to classify traffic passing through the Ethernet switch
into prioritized flows.
Each port can have a priority tag set at the ingress port, or it can be read directly from the Ethernet
traffic. When read directly from the Ethernet traffic, the following fields are used to determine the
traffic’s QoS priority.
The IEEE 802.1p Priority information in the IEEE 802.3ac Tag. The IPv4 Type of Service field. The IPv6 Traffic Class field.
You can select one of two queuing methods:
IEEE 802.1p standard method Cisco-proprietary method
The queuing method determines how the traffic is prioritized.
Each port has four egress queues (queues 0-3) of differing priorities. Queue 0 is the lowest priority and
Queue 3 is the highest priority.
