the United States (or where FCC rules apply), only those antennas certified with the product
are used. The use of any antenna other than those certified with the product is expressly
forbidden in accordance to FCC rules CFR47 part 15.204.
The installer should configure the output power level of antennas, according to country
regulations and per antenna type.
Note:
Outdoor units and antennas should be installed ONLY by experienced installation professionals
who are familiar with local building and safety codes and, wherever applicable, are licensed by
the appropriate government regulatory authorities. Failure to do so may void the WinLink™
1000 warranty and may expose the end user or the service provider to legal and financial
liabilities. RADWIN and its resellers or distributors are not liable for injury, damage or violation
of regulations associated with the installation of outdoor units or antennas.

Overview
WinLink™ 1000 System Components
WinLink™ 1000 point-to-point solution is made up of a number of key
components.
Typically, each side of the link comprises an Indoor Unit (IDU), an
Outdoor Unit (ODU) and an antenna. A CAT5e cable from the IDU to
the ODU provides both Ethernet and Power. The link is managed via
the WinLink™ 1000 Manager application.
Figure 2-1: Example of Link Architecture
WinLink User and Installation Guide Version 1.795 2-8
The Indoor Unit (IDU)
The IDU provides TDM and Ethernet ports to connect to the link. It
also provides power to the ODU. The IDU is available in four
configurations:
IDU-E
A compact, half 19 inch wide, 1U plastic unit, providing up to two
Ethernet ports and up to two E1/T1 interfaces.
Figure 2-2: IDU-E Front Panel
Figure 2-3: IDU-E Back Panel
IDU-C
A 19 inch, 1U metal unit, providing two Ethernet ports, 4xE1/T1
interfaces, and dry contact connector alarm.
Figure 2-4: IDU-C Front Panel
IDU-R
A compact, half 19 inch, 1U plastic unit for 1 x T1/E1 backup, providing
in addition 2 Ethernet ports and an external alarms interface. IDU-R is
an indoor unit used for automatic backup of leased lines. IDU-R
monitors the status of leased lines, and in the event of a connection
failure automatically switches to the radio link. The user configures
which of the two links is the main link and which is the backup link.
IDU-R operates with all WinLink™ 1000 outdoor units.
Figure 2-5: IDU-R Front Panel

Similar to the PoE, with weatherproof casing and sealed
connectors that enables outdoor connectivity (a special
mounting kit is supplied for attachment to a mast).
Figure 2-10: O-PoE Unit
The Outdoor Unit (ODU)
The ODU is the radio transceiver of the WinLink system and is the
main component of the system. The ODU connects to an antenna that
enables radio communication and can be mounted on a pole or wall.
The ODU connects to the IDU via a CAT5e cable.
ODUs are available in different frequencies and regulations in the
ranges: 2.3-2.7GHz, 4.9-5.95GHz.
The ODU comes in two different form factors depending on the type of
antenna:
• ODU with integrated 1ft flat panel antenna. This unit
contains both the ODU and antenna as a single unit housed in a
weatherproof casing.
• ODU with a connector for an external antenna. The unit
is fitted with an N-type connector. An external antenna can
extend the range of the link, and in some cases, may help to
reduce environmental interferences.
Various external antennas are available for the WinLink™ 1000
operating frequencies.
Figure 2-11: ODU with integrated antenna

Mounting the ODU
The ODU is the transceiver element of the WinLink system. The ODU
can be mounted on a mast or a wall. In both installations, the supplied
mounting kit is used to secure the ODU.
Mast and Wall Installation describes the mast/wall installation
instructions.
A WinLink link operates in pairs of two ODUs with the same
configuration. Both ODUs must be installed, and the antennas aligned
for maximum throughput.
WinLink User and Installation Guide Version 1.795 3-26
Prior to connecting cables to the ODU, the protective earth terminal
(screw) of the ODU must be connected to an external protective
ground conductor or to a grounded mast. For grounding the O-PoE,
connect the grounding cable from the dedicated earth terminal (screw
at the side of the enclosure) to an external protective ground
conductor or to a grounded mast.
Only a qualified person using the proper safety equipment should climb
the antenna mast. Only trained professional installers should be used
when installing or dismantling ODUs and masts.
To mount the ODU:
1. Verify that the ODU mounting brackets are properly grounded.
2. Mount the ODU onto the mast or wall. Ensure that the unit is
oriented so that the cable connectors are at the bottom. (If they
are on top, water may penetrate into the unit causing
damage.) Refer to
Mast and Wall Installation for the ODU or O-PoE mounting
instructions.
3. Connect the ground cable to the chassis point on the ODU.
4. Attach the ODU-IDU cable to the ODU RJ-45 connector. If making
own ODU-IDU cable, refer to
Wiring Specifications for the connector pin-out.
5. Screw in the cable glands to ensure hermetic sealing of the ODU.
6. Secure the cable to the mast or brackets using UV-rated cable ties.
7. Repeat the procedure at the remote site.
2.
Note:
Do not tightly secure the ODU to its mounting brackets until the
alignment process of the antenna is complete.
When installing the ODU, check that there are no direct obstructions in
front of the ODU or interference from man-made obstacles.
For O-PoE UL Listed parts and components must be used for
installation. Use UL listed devices having an environmental rating equal
to or better than the enclosure rating to close all unfilled openings.

Connecting the ODU to the IDU
The ODU-IDU cable conducts all the user traffic between the IDU and
the ODU. The ODU-IDU cable also provides -48 VDC supply and
Ethernet to the ODU. The maximum length for one leg of the ODU-IDU
cable is 100m (328 ft) in accordance with 10/100BaseT standards.
When using an O-PoE or PoE-8, the maximum length for two legs of
the O-PoE or PoE-8 cable is 100m (328 ft) in accordance with
10/100BaseT standards.
The ODU-IDU cable is supplied pre-assembled with RJ-45 connectors,
at the length specified when ordering. If the ODU-IDU cable was not
ordered, use Cat. 5e 24AWG shielded cable. Wiring specifications are
given in
Wiring Specifications.
To connect the ODU to the IDU
1. Route the cable from the ODU to the IDU.
2. Secure the cable along its path.
3. Connect the ODU-IDU cable to the RJ-45 connector on the IDU.
The figures below illustrate typical IDU panels. You may have
differences in your panels depending on the hardware ordered.

Note:
Panels may be fitted with different connector combinations than
shown, depending on the model ordered.
IDU-R Installation
Installation of an IDU-R unit differs from other IDU models in one
respect: At the rear of the IDU-R (see Figure 2-6 above) there are two
jacks labeled “Trunks”. For each IDU-R, the E1 cable from outside
should be plugged into one of the trunks, and the E1 cable to the other
WinLink User and Installation Guide Version 1.795 3-29
station should be plugged into the second trunk, as in the left hand
side of Figure 2-7 above.
Apart from the above difference, the link installation including the
remaining part of the IDU installation and connection to the ODU
proceeds as described as above.
Connecting the Ground to the IDU
Connect an 18AWG grounding cable to the grounding terminal of the
device. The device should be permanently connected to the ground.
Connecting Power to an IDU
AC power is supplied to the WinLink™ 1000 IDU through a standard
IEC 60320 connector.
AC power should be supplied via a 1.5m (5 ft) standard power cable
terminated by a IEC 60320 socket. A cable is provided with the unit.
To connect AC power to an IDU:
Connect the power cable socket to the power connector on the
WinLink front panel.
• Connect the power cable plug to the mains outlet.
The unit turns on automatically upon connection to the mains.
To connect DC power to an IDU
A special 3-prong socket for DC power connection is supplied with the
unit.
Connecting Power to an O-PoE
AC power is supplied to the O-PoE via a 3m (10 ft) 3 wire AC cable
attached to the unit (pigtail). The AC cable is provided with no
termination.
To connect AC power to an O-PoE:
Connect the power cable to a protected/shielded AC mains outlet.
The AC mains outlet should be provided with circuit breaker rated 5A
according to the local national electrical code.
The unit will be turned on automatically upon connection to the mains.
To maintain Overvoltage (Installation) Category II, install a suitable
surge suppressor device in the branch circuit to limit expected
transients to Overvoltage Category II values.
The limits are based on IEC60664 and are also located in Table 2H of
UL60950 (for mains ≤ 150V, the transient rating is 1500V;
Warning
WinLink User and Installation Guide Version 1.795 3-30
for 150V < mains ≤ 300V, the transient rating is 2500V;
for 300V < mains ≤ 600V, the transient rating is 4000V).
Aligning Antennas with the Beeper
Perform the antenna alignment using the ODU’s audible tone. The tone
is not suitable for aligning the All Indoor Units (AIND). To align an
AIND system, see
AIND Alignment.
To speed up the installation time, alignment of a WinLink™ 1000
system should be performed by two teams simultaneously, at site
A and at site B.
Æ To align the ODUs using the alignment tone:
1. Verify that power is connected to the IDUs at both sites.
Do not stand in front of a live ODU.
Provided that Site A detects the signal from Site B, the ODU starts
beeping 20 seconds after power up, and continues beeping until
the ODUs are aligned, and the installation is complete.
2. Verify normal operation of the IDU by the LED indications on the
front panel. See IDU Front Panel Indicators.
3. Direct the antenna of site B in the direction of the site A. This is
simplified if a previous site survey has been completed and
azimuths are known.
4. Make an azimuth sweep of 180 degrees with the site A ODU so that
the strongest signal from site B can be detected.
5. Slowly turning the site A ODU back towards the position of Site B,
listen to the tone until the best signal is reached. See the following
figure for audible signal variations.
Warning
WinLink User and Installation Guide Version 1.795 3-31
Figure 3-8: Beeper Sequence for ODU Alignment
Note:
Three beeps and a pause is the best signal
Two beeps and a pause, signal quality increased
One beep and pause is no signal change
Any other signal detects no signal between ODUs.
6. Secure the site A ODU to the mast/wall.
7. At site B, adjust the ODU slowly whilst listening to the beeper
sequence until the best signal is attained.
8. Secure the site B ODU to the mast/wall.
9. Monitor the link quality for about 15 minutes to verify stability.

allows you to define several allowable frequency channels to which you
can change if interference is detected on the channel in use. ACS
performs channel monitoring and selects the channel with the lowest
interference for the transmission.
Automatic Channel Select enables coexistence with any radar system
that may be active in the area.
Note: For the ETSI version, skip to page 5-62; for the BRS version,
skip to page 5-64.

The 5.4 GHz ETSI Version
In accordance with ETSI, unlicensed wireless data equipment is not
allowed to interrupt radar services. Therefore, if the ETSI Version
detects Radar activity, it automatically changes the frequency channel.
This feature is termed Dynamic Frequency Selection (DFS). According
to the standard, a channel with active Radar is prohibited from use for
30 minutes. Before any transmission, WinLink™ probes a channel for
Radar signals for a period of 60 seconds.
In the 5.4 GHz ETSI version, the Automatic Channel Selection is
selected by default and a minimum of two channels must be defined as
available.
Figure 5-4: Channel Select dialog box (DFS, ETSI requirement)

Configuring Service Parameters
You define the type of service required, Ethernet Only or Ethernet with
TDM. The bandwidth remaining available for Ethernet if TDM services
are required is shown in the dialog box.
Note:
ACCESS versions are Ethernet Only.
In the Service Parameters dialog box select the number of E1
connections (x1 or x2 for IDU-E, or x4 for IDU-C). Define the required
transmission rate, and the distance between the sites.
Æ To configure E1/T1 and Ethernet services:
1. In the Service dialog box, select one of the following:
• Ethernet plus a number of E1/T1 channels (see
Figure
5-6
).
• Ethernet data only.
2. Select the transmission rate required.
• Adaptive
• 9 Mbps
• 12 Mbps
• 18 Mps
• 24 Mbps
• 36 Mbps
• 48 Mbps
The default rate is Adaptive. ACCESS versions only operate in
Adaptive mode.
Adaptive Modulation - The system changes modulation
automatically depending on channel characteristics in order to
guarantee continuation of service. The adaptive modulation
enables the user to maximize Ethernet throughput without
degradation of the TDM service quality. When Ethernet only service
is used, the adaptive modulation enables improving the Ethernet
performance in case of air performance degradation (periodical
interference or RSS changes).
In event of interference at one site, there is no need to use a lower
modulation at the other site (as in previous versions). In such a
case the actual rate changes automatically only at the problematic
WinLink User and Installation Guide Version 1.795 5-66
site, while the second side of the link maintains the highest rate
possible (Asymmetric).
Adaptive modulation can be changed in both Installation and
Configuration wizards.
For versions 1.6 and greater, distance between the sites is
automatically measured.
If TDM services are selected, then the Evaluate icon shows on the
screen while the maximum rate is evaluated.
When evaluation is complete the icon changes and the following
message is shown:
Service has been evaluated, click Next to continue.

used for the traffic sent from the ODU to the management
workstation. VLAN management affects all types of management
connections (local, network and over the air).
7. Enter a Priority number.
Figure 5-14: Configuring VLAN Settings
Changing this parameter causes the management application to
immediately disconnect. In order to avoid problems, it is recommended
to verify the change by setting the VLAN only to one ODU, and only
after verifying the VLAN network operation, change the other VLAN
setting can be changed.
Warning
WinLink User and Installation Guide Version 1.795 5-77
Troubleshooting:
If the VLAN ID is forgotten or there is no VLAN network connected to
the ODU:
• Reset the device.
In the first two minutes both VLAN and no VLAN connections
are available.
Setting the Date and Time
The ODU maintains a date and time value. The date and time value
should be synchronized with any Network Time Protocol (NTP) version
3 compatible server1. On power-up the ODU configures the initial date
and time using an NTP server. If the server IP is not configured or is
not reachable, a default time is set. When configuring the NTP server
IP, you should also configure the offset from the Universal Coordinated
Time (UTC). If there is no server available, you can either set the date
and time, or you can set the manager workstation time. Note that
manual setting is not recommended since reset, power up, or
synchronization with an NTP server will override the setting.
Note:
The NTP uses UDP port 123. If a firewall is configured between the
ODU and the NTP server this port must be opened
2
.
It can take up to 8 minutes for the NTP to synchronize the ODU date
and time.
Æ To set Date and time

WinLink User and Installation Guide Version 1.795 5-79
parameters are located under the Advanced tab of the Configuration
dialog box:
Figure 5-17: Bridge Configuration - Site Configuration dialog box
ODU Bridge Mode
This parameter controls the ODU mode with two optional values,
• Hub Mode – in Hub mode the ODU transparently forwards the
all the packets over the wireless link.
• Bridge Mode – In Bridge mode the ODU performs both
learning and aging, the aging time of the ODU is fixed at 300
seconds.
Note:
Changing these modes requires system reset.
IDU Aging time
This parameter controls the IDU aging time.
The IDU has a 2047 MAC address-learning table. The aging time
parameter controls the time each MAC address is dropped from the
table.
Default value is 300 seconds.
WinLink User and Installation Guide Version 1.795 5-80
Note:
Any change to these parameters is effective immediately.
Each side of the link can be configured separately.
• The following list details common configurations; both sides
are must be configured with the same parameter.
• Standard (Default) Configuration for Ethernet Applications
• Set IDU aging to 300 seconds, ODU set to Bridge mode
• Fast aging mode – for rapid network topology changes
• Set IDU aging to one second, ODU set to Hub mode.
• Hub Mode
• The ODU is set to HUB mode. IDU aging is not applicable.
• Ethernet Bridge
The ODU is set to Bridge mode. The IDU aging is not applicable.
Configuring Ethernet Mode
The Ethernet mode is configurable for line speed (10/100BaseT) and
duplex mode (half or full duplex). This mode provides an Auto detect
feature where the line speed and duplex mode are detected
automatically using auto negotiation. Use the manual configuration
when external equipment does not support auto negotiation. The
default setting is Auto Detect.
The maximum Ethernet Information Rate can be limited via the pull
down menu. The default setting is Best Effort.
Note:
It is not recommended to configure the port that is used for the
management connection, since a wrong configuration can cause
management disconnection or Ethernet services interruption.
Æ To configure the Ethernet Mode:
1. From the Configuration menu, select the site to reconfigure.
The Site Configuration dialog box opens.
2. Click Advanced > Ethernet.
3. In the Ethernet Ports Configuration pane, use the drop-down menu
to select the LAN configuration.
WinLink User and Installation Guide Version 1.795 5-81
4. Click Apply to save the changes.
Note:
It is possible to close the Ethernet service by disconnecting the
Ethernet port. The user should be aware that it is possible to close the
port and not have any access to the device. If this should occur the
workaround is as follows:
• Connect the system from the remote site
• Connect via other Ethernet port (IDU-C)
• Power down the equipment and connect immediately after the
power up (the fastest way is to enter install mode).
Setting the Maximum Information Rate
The maximum Ethernet throughput of the link can be limited. The
default setting is Best Effort, where the highest information rate
available for the link conditions and settings is used.
Æ To set the Ethernet information rate:
1. From the Configuration menu, select the site to reconfigure.

Configuring the Jitter Buffer
By configuring the Jitter Buffer, the receiver jitter buffer for each site
can be enlarged, thereby increasing system resistance to interference
(the larger the jitter buffer, the longer the interference period that the
system will overcome without TDM BER). You can also decrease the
jitter buffer to decrease the system delay.
The jitter buffer can be configured between 2.1 and 16.0 milliseconds.
WinLink User and Installation Guide Version 1.795 5-82
Æ To configure the Jitter Buffer:
1. In the Main menu click the Link Configuration button.
2. Run the Configuration wizard (see
Figure
5-1
).
3. On the Services screen, select the TDM Jitter Buffer tab:
Figure 5-18: Jitter Buffer Configuration
4. Choose the desired values for HQ and Remote Site.
After setting the new value, the user must evaluate the expected
quality. During the evaluation the ETBE bar is displayed.
5. Click Next > to perform the change or < Back to cancel the
change.
Extra caution should be use when decreasing the value, since the
service quality might be affected in the case of interference. In cases
of asymmetric interference, the jitter buffer can be set to different
values per site. In such cases the latency will also be asymmetric.

WinLink User and Installation Guide Version 1.795 5-83
Changing Community Values
The ODU communicates with the management application using
SNMPv1 protocol. The protocol defines three types of communities:
• Read-Only for retrieving information from the ODU
• Read-Write to configure and control the ODU
• Trap used by the ODU to issue traps.
The community string must be entered at login. The user must know
the password and the correct community string in order to gain access
to the system. A user may have read-only privileges.
It is not possible to manage the ODU if the read-write or the read
community values are forgotten. A new community value may be
obtained from technical support for the purpose of setting new
community; the serial number or the MAC address of the ODU must be
supplied.
Note:
The manager application and the ODU use the community strings
public-bru1 for the local unit and public-bru4097 for the remote
unit. These are the factory defaults, but can only be used one time on
the first installation.
A new community string must be set when entering the system for the
first time. The read-write community and read-only community have a
minimum of five alphanumeric characters. (Bru1 and bru4097 are not
permitted). Changing the trap community is optional by clicking the
check box.
Editing Community Strings
The community change dialog box is available from the
Configuration > Security tab. Both read-write and read-only
communities must be defined.
On entering for the first time, use the following as the current
community:
• For Read/Write community, use netman.
• For Read Only community, use public.
• For Trap community, use public-bru1.
Æ To change a community:
1. From the Configuration dialog box, select the Security tab
2. Type the current read-write community (default is netman).
WinLink User and Installation Guide Version 1.795 5-84
3. Select the communities to be changed by clicking the check box.
4. Type the new community and re-type to confirm.
5. Click OK to save.
Figure 5-19: Changing the Community String
Forgotten Community string
If the read-write community string is unknown, an alternative
community key can be used. The alternative community key is unique
per ODU and can be used only in order to change the community
strings. The alternative community key is supplied with the product,
and it is recommended to keep it safe.
If both the read-write community and the alternative community key
are unavailable, then an alternative community key can be obtained
from customer support using the ODU serial number or MAC address.
The serial number is located on the product, and the MAC address is
displayed in the manager inventory tab.

Link Lock Security Feature
The purpose of Link Lock
Link Lock is a part of the WinLink security concept intended to meet a
form of abuse encountered in the field. It is designed to prevent the
situation where a remote ODU can be stolen and used as a “pirate” link
to steal services or information. The Link Lock feature actually locks
the local ODU to be synchronized ONLY to specific remote ODU. It is a
site oriented feature.
The lock can only be set from a live link. It is based on MAC
authentication and is site oriented and activated on a per ODU basis.
For example, if you lock the remote ODU to the local ODU, you must
still lock the local ODU to the remote ODU to ensure complete two way
locking.
It can only be removed when the link is unsynchronized. In such a
case, an alarm is raised by the WinLink™ 1000 Manager.
Æ To enable Link Lock:
1. From the Link Configuration menu, select “1 Configuration
Location A”.
2. Choose the Security tab. The following window is displayed:
3. Click the Link Lock checkbox and then OK. You are asked to
confirm the lock:
WinLink User and Installation Guide Version 1.795 5-94
4. Click the Yes button and you are returned to the main window of
the WinLink ™ 1000 Manager.
Observe that a link icon is now displayed in the status bar on the
bottom right of the WinLink™ 1000 Manager window.
The link to the remote unit is now locked. If you repeat steps 1 and 2
above, the Security screen will look like this:
The Link Lock checkbox is now unavailable.
Note:
The Link Lock status will only revert to unlocked as a result of a broken
link, for example due to an ODU being switched off at either end of the
link.
A simple ODU reset at either end will restore the link to its previous
locked or unlocked state.
Chapter 6
Monitoring and Testing
the Link
The WinLink™ 1000 Manager software enables you to monitor the link,
as well as perform Loopback tests. It also provides a handy Link
calculator utility for calculating the expected performance of the
wireless link and the possible RF and antenna configurations for a
specific link range.
Retrieving Link Information (Get Link Information)
The Get Link Information feature collects and writes all link and
Manager information (from both sides) into a comprehensive file. The
file can be used for diagnostics and should be sent to technical support
to speed up assistance.

The Link Budget Calculator
The Link Budget Calculator is part of the WinLink™ 1000 Manager
software and is found in the Help menu. This useful utility enables you
to calculate the expected performance of the wireless link and the
possible configurations for a specific link range including antenna size,
cable loss and climate conditions.
The Link Budget Calculator enables you to calculate the expected RSS
of the link, and determine the stability of services and their effective
throughput as a function of the link range and deployment conditions.
The Link Budget Calculator is found on the Installation CD and from
tech support so it can be used prior to installation to define and verify
link parameters such as expected RSS, maximum range, and number
of E1s/T1s that a link is capable of providing. It enables verification of
installation quality and provides calculations that consider “real world”
factors such as climate.
The Link Budget Calculator screen appears in the following figure.
WinLink User and Installation Guide Version 1.795 6-102
Figure 6-7: WinLink™ 1000 - Link Budget Calculator
Performance Monitoring
Performance Monitoring constantly monitors traffic over the radio link
and collects the following statistics data:
• Site 1/Site 2 received traffic rate (in Mbps)
• Site 1/Site 2 received frames rate (in Mbps)
• Radio signal strength (in dBm)
• Error (Blocks).
WinLink™ 1000 monitors the Air interface, ETH ports, and TDM trunks.
It does so continuously, even when the WinLink™ 1000 Manager is not
connected.
Two types of logs are recorded:
y Monitor log that records statistics on traffic rate and radio
signal strength.
y Events log that records when the rates fall above or below a
predefined threshold.
Both the statistics (monitor) log and event log can be saved as TXT
files.
WinLink User and Installation Guide Version 1.795 6-103

Viewing Performance Reports
The Performance Monitor Report displays performance views of each
of the interfaces3:
Figure 6-9: Performance Monitoring Report window
Several performance data occurrences are collected for each of the
interfaces (ES, SES, and UAS), as well as Specific data per Interface
type (e.g., TX and RX bytes for Ethernet). For the Air Interface, user
defined thresholds data are collected. Refer to
3 Ethernet performance is not collected in PoE systems.
WinLink User and Installation Guide Version 1.795 6-105
Table
6-3
and
Table
6-4, Performance Monitoring Report Toolbar.
Data is collected and selectively displayed based on three time
intervals as selected by the Interval radio buttons:
• Current (t=0)
• 15 minutes Intervals
• Daily.
UAS – This parameter counts the time the air link was not providing
any service. There are several potential reasons for this situation; one
of the sites has a power failure, high interference, maintenance
operation, etc.
Radio BBER Threshold – This parameter counts the seconds in which
the radio performance is below a user specified threshold. The
threshold is measured in percent. The threshold can be set from 0.1%
up to 50%.
For links with E1/T1 service the recommended value is 1% (system
default). Excellent TDM service is expected below the 1% threshold,
meaning that for 1% threshold, the expected BBER value should be 0
if there are no problems during the 15 min interval. If the BBER
threshold increases a degraded service might be noticed.
For links with Ethernet only service, 8% threshold is recommended and
not 1% meaning that for 8% threshold, the recommended BBER value
should be 0 if there are no problems during the 15 min interval. Since
the system provides a loss less Ethernet service, there is throughput
degradation in case of interference. The degradation is proportional to
the BBER.
Radio RSS Threshold - Radio RSS Threshold can also be used to
indicate problems in the radio channel. You can verify the RSS
according to the link budget calculator during the installation. A value
of -5dB from the current RSS is recommended as a threshold.

Chapter 7
Security
WinLink™ 1000’s integrated advanced encryption support provides
enhanced air interface security for carriers and private networks by
ensuring user data protection with one of the most sophisticated
commercially available combined encryption and authentication
techniques, CCM/AES. This technique combines message
authentication (preventing anti-spoofing and replay protection) with
commercial encryption, and complies with the IEEE 802.11i (phase iii)
security recommendations.
CCM/AES uses a symmetric 128-bit encryption key (EK), and a nonce,
and provides both message encryption and authenticating signature.
The nonce mechanism enables the receiver to remember already
received genuine messages and reject all replayed messages.
Initial encryption and authentication is based on a user-defined master
key (Link Password). While standard Wireless LAN encrypts only the
Ethernet Payload, the AES encrypts both the source and destination
MAC addresses.
Entering and Changing Passwords
There are two passwords necessary to use the WinLink system:
• Management Password required for running the Management
software
• Link Password used for encryption purposes. This link
password is entered when installing or configuring the link.
Changing the Management Password
Æ To change the management password
1. From the Tools menu, select Change Password.
The Change Password dialog box appears.
2. Enter the current password, and the new password.
3. Click OK to confirm.
