Introduction
Gigalink Product Family
The Terabeam® Gigalink millimeter wave radio system represents an entirely new
approach to broadband communications. Based on our extensive experience with millimeter
wave systems for military and research applications, we now apply these techniques to a
commercially priced version with our ultra-broadband family of Gigalink radio products.
The Gigalink broadband radio system operates in the FCC Part 15.255 unlicensed band
covering a frequency range of 57.05 – 64.0 GHz. Due to the unlicensed status of this band,
FCC license or special authorization is not required to operate our Gigalink systems. In
addition, the high atmospheric absorption of RF energy at this frequency virtually eliminates
any chance of interference from competing systems or unauthorized interception of the
broadcast signal.
The installation procedures detailed within this guide are similar to those used to install any
wireless system. In fact, certain attributes of the 57.05 – 64.0 GHz band actually simplify
deployment. The key to any successful installation project is proper planning and design. The
Gigalink radio product has been designed for ease of installation and trouble-free operation.
We recommend that you read and fully understand this guide prior to initiating the actual
installation work.
As stated above, the key to successful installation is proper system planning and execution.
As with most wireless systems, the Gigalink radio system requires un-obstructed Line of
Sight (LOS) to operate reliably. Because of the extremely high data bandwidth provided by
the Gigalink system (1.25Gbps) it is likely that our radio systems will be utilized as a critical
or primary network connection. This absolute reliance on our systems for connectivity
demands a focused attention to detail in order to assure un-interrupted operation.
Reliability
All Gigalink products are designed to provide a minimum statistical path availability of
99.99% (BER < 1 x 10 –9) when operated within the recommended range envelope.
Exceeding the specific model range restrictions will result in unreliable operation particularly
during adverse weather.
Statistical availabilities in excess of 99.99% may be achieved by choosing the next longer
range system for a given path or by co-locating two Gigalink systems. Traditional circuit
redundancy methods utilizing collapsible ring architectures or media diversity may also
increase statistical availability.

Rough Mechanical (Visual) Alignment
Once the Gigalink Radio Terminals are securely fastened to the mounting locations, the
installer should visually align the terminals. Visual alignment is accomplished by loosening
both the C Bracket Attachment bolts and L Bracket Mounting bolts slightly. With these (7)
bolts loosened the terminal can be aligned (aimed) toward the other terminal by sighting
along the radio housing body.
Once satisfied that both terminals are aimed at the each other, all seven bolts can be snagged
up enough just to hold the desired position.

Final Terminal Alignment
NOTE: Although it is possible for a single technician to perform final terminal
alignment. Terabeam recommends that two technicians with monitor-enabled
laptops be dedicated to this task. By dedicating two technicians equipped with
cellular phones or two-way radios, final alignment can be accomplished at both
terminal sites concurrently, eliminating the need to constantly travel between sites.
Radio Terminal Power-Up
Once the Radio terminals have been mechanically mounted in place and visually aligned,
both radio terminals must be powered up, and network services connected.
Terminal Power up
Power-up the Gigalink terminal as follows.
1. Attach DC power cord securely to the radio terminal
2. Attach power leads to –48VDC source Red to –48VDC supply, Black to –48VDC return
and Green to Building Ground.
3. Power up –48VDC circuit.
4. Verify power on condition via Green “Power-on” LED’s located on the bottom of the
terminal housing
Connecting Network Services
Once the power has been applied to the Gigalink terminal, Network services can be
connected and verified. The network Fiber connections to the Gigalink terminal are Type FC
male terminated fiber optic cables. Make these connections by aligning the connector body
index tab, then tightening the outer collar in a clockwise rotation.
In the network switch room, insert the other end of each fiber optic cable into the appropriate
TX and RX switch ports. If done correctly, a link light should be visible. If no link light is
visible, make sure the radio is powered up and swap the fibers.

Current Receive Level
When in the “Align”, “Run” mode the Gigamon monitor displays a continually updated
receive level. The task during precision alignment is to maximize or peak the receive level.
Precision alignment is made in both the vertical and horizontal plane (up and down, left and
right) separately, one terminal at a time.
Begin alignment by aiming the radio terminal slowly up while observing the change in
receive level. Typically, the receive level will rise, then fall and then rise again slightly on
both sides of the optimum alignment as the receiver moves from the center main beam to the
edge side-lobes of the radiation pattern. It is recommended that the technician move the
alignment through the main lobe and into both side-lobes until returning to the center peak

receive level. When satisfied that the maximum receive level has been reached, tighten the
Gimbal side adjuster bolts to hold the desired vertical alignment angle. To facilitate this task,
Gigamon displays the highest receive level recorded as a magenta bar at the top of the
receive level bar.
Repeat this procedure for the Azimuth (Horizontal) alignment by slightly loosening the
Gimbal base mounting bolts and rotating the alignment from right to left. Again, by
observing changes in the receive level monitor, identify both side-lobe areas and return the
alignment to the center “Peak” position.
Repeat the previous two alignment procedures at the other Gigalink terminal while
maintaining the position of the original terminal. During these procedures, the receive level
should continuously improve. Optimum terminal alignment is best accomplished by small
adjustments at both terminal sites.
NOTE: Precision alignments are made most easily by make very slight incremental
adjustments to the radio alignment. Care must be taken not to over-adjust the
alignment. To facilitate precision alignment, tighten all adjusting bolts to allow
movement only when bumping terminal firmly with your hand.
An acceptable receive level will be indicated by the Blue Gigamon receive level indicator as
a level approaching the Maximum recorded receive level (Magenta line) and as a level falling
somewhere in the upper half of the green region behind the blue indicator bar. An acceptable
numeric measure would be a level above 450 as indicated by the large level number
displayed below the receive level indicator.
When satisfied that optimum alignment has been achieved, tighten the (3) Gimbal base
mounting bolts and the (4) Gimbal side adjuster bolts to secure the desired position.
As a final installation step, perform the “Save GigaMon Information in a File as” operation
as prompted when exiting the application. The saved radio parameter information can be
used for future comparisons to gauge ongoing radio performance.
Verifying Network Operation
Once an acceptable (optimum) receive level has been achieved, the Gigalink system will
provide an error free RF link between the two network devices at both sites. If no link is
obtained, check the network fiber, routing table configurations and other network parameters.
If an error free link still cannot be established, consult the Troubleshooting/Diagnostic
section of the Gigalink User’s Manual.

Before going into the operating details, some terminology, and the color convention used
should be explained.
Terminology
•
‘Monitoring’ is an action state defined as ‘Runmode’/’Alignment’ and/or reading current
Gigalink terminal parameters. ‘Runmode’ is the state where Gigamon reads the Gigalink
terminal parameters (specially for Rx Power/Receive Level) while continuously updating
the display.
•
‘Setting Network Parameters” ,“Setting Threshold Parameters” and “Setting Factory
Parameter” are all part of “Configuring Gigalink”. Setting a parameter means saving that
value in Gigalink terminal’s EEPROM image, once saved the terminal will keep the new
values even if Gigalink terminal is powered off and back on.

•
MAC Address: The MAC or Hardware address off the Gigamon utility resident in the
Gigalink terminal. This unique address is set at the factory and cannot be changed.
Initially the Gigamon program does not know this MAC address of the connected
Gigalink(s), and so the value “Unknown” is displayed. When ‘Refresh’ is selected from
Action menu, the program tries to get the MAC addresses of all the Gigalink terminals
connected to the network segment, and then ‘Unknown’ value becomes the MAC address
of the first Gigalink terminal MAC address detected. By default, the first Gigalink
terminal detected during refresh becomes the “Currently Selected” Gigalink.
•
Serial Number: This value is set at the factory and cannot be changed. The value
displayed, also corresponds to the currently selected Gigalink.

Synthesizer, PLL, TX Link, and RX Link: These are discrete values that indicate an
acceptable or unacceptable state for critical monitoring points within the Gigalink radio
terminal. The rectangles associated with the Synthesizer and PLL Lock display green if
they are locked (acceptable), or display red if unlocked (unacceptable). The rectangles for
Tx Link and Rx Link are green if an optical signal is present on the fiber segment, and
turn red if no signal is present.
•
Rx Power: In “Align/Run” mode, the blue rectangle represents current Receive Level. If
‘Run’ is chosen from the ‘Align’ submenu of ‘Action’ menu, it starts displaying this
value continuously. A higher Rx Power indicates better alignment. As the user does
adjustment in “Run” mode changing the Gigalink terminal alignment, Rx Power varies. A
magenta, horizontal, line is displayed on the top of the blue receive level rectangle
indicates the highest/maximum value reached so far. A numeric value of the maximum
receive level is displayed adjacent to the magenta line. The blue inner rectangle
represents the current value. The current Rx Power’s numeric value is also shown below
the rectangle in a large font to facilitate alignment with higher visibility.
•
6 Volt, 15 Volt, -15 Volt, Vtune, Gunn: These are other variable values. During
‘Refresh’ and ‘Run’, Gigamon retrieves the current values and displays these values as a
blue horizontal line. These rectangles are divided into safe, warning and danger regions.
If the current value is the optimum then the blue line should be at the middle. For 6 Volt
rectangle, the optimum value is 6.10, top to middle, or bottom to middle is the 10% of
optimum value, and so, for 6 volt top=6.1+(0.61*1)=6.71, and bottom=6.1(0.61*1)=5.49. For all others, top to middle, or bottom to middle is 40% of the optimum
value. So for 15 Volt, the optimum value is 15.0, top=15.0+(1.5*4)= 21.0, bottom=15.06.0=9.0. The optimum values of –15 Volt, 24 Volt and Gunn are 15.0, 24.0, and 850
respectively.
•
Status bar: The status bar at the bottom of the screen is for displaying current status,
error, and some numeric values. Errors and status are shown at the left, and values at the
right. Most importantly, during refresh, it shows the numeric value of all variable
parameters.

“Select Current Radio/ Gigalink” Screen
The “Select Current Radio/Gigalink” window displays the factory-set parameters
of the currently selected/active Gigalink at the top and a combo box (list) of MAC
addresses for all the Gigalink terminals found. Choosing a different MAC address
from the combo list updates serial number field with corresponding value for that
terminal. If ‘Select’ and then ‘OK’ buttons are pressed then Gigamon selects
only the radio with the MAC address currently selected in “Gigalink Radio
MAC Address” combo box as the currently selected/active Gigalink. Pressing
‘Cancel’ button after ‘Select’ undoes the selection and keeps previous selection
of currently active radio.
− ‘Save Info As’ to open a dialog box “Save Gigalink Info in a File As” for the
user to select a text filename to save all the parameters for all the Gigalink
terminals detected. The dialog box shows the default filename as “Gigalink.txt”.
The user can type/select any filename and save to any location. Gigamon will
create the file if does not exist or open the file without deleting old data if it
already exists.

The “Save Gigalink Info” command will write/append a line of parameter values
for each Gigalink terminal detected in the current session. These values are tab
delimited, and so they can be copied and pasted into an Excel spreadsheet. Each
line/record has timestamps (date and time) with seconds resolution so the saved
file may have several lines for the same Gigalink terminal if appending to an
existing file or the user chooses ‘Save Info As’ several time during the current
session. But the time-stamp will be unique for each line. The file content will be
saved in the format shown below:

“Network and Security Settings” Screen
This dialog box displays the MAC and serial number of the currently selected
Gigalink as read-only text. It also shows the current (Factory default) values of
the following SNMP related settable/configurable parameters:
− Gigalink SNMP Agent IP: This value is needed for any SNMP monitoring
software to request a Gigalink for any SNMP variable’s value or to change value
(SNMP Get/Set functions). It is also needed for SNMP monitoring software to
distinguish the source of any SNMP trap packet sent by any Gigalink terminal. It
may also be required for many other network activities like pinging a Gigalink
terminal since this communication protocol uses IP packets. An IP-Address/NetMask consists of 4 octets separated by dots and each octet’s range is 0 to 255.

− Subnet Mask, and Gateway IP: These parameters define which IP address range
will be local for the Gigalink terminal. When the Gigalink terminal sends an IP
packet, it does logical AND between this Subnet Mask and destination IP address
to find out if the destination is in its local subnet. The Gigalink terminal needs to
know the local “Subnet Mask” because if the destination is not within its local
network, the Gigalink terminal will send the packet to the default destination, the
Gateway, which is a router. For this reason, the Gateway/router’s IP address must
be defined as well.
− SNMP Manager IP: The Gigamon user must define the IP address of the
computer/host acting as SNMP Manager so that Gigalink terminal can send
SNMP traps to the host.
− Report Frequency: The Gigamon user must define how frequently each radio
terminal will send SNMP trap packets to the SNMP Manager reporting the status
of the SNMP variables. The combo box gives list of report intervals to choose
from. If ‘Unknown’ is chosen, pressing ‘Apply’ button will send the new
parameter values to the currently selected Gigalink and write that value into
Gigalink terminal EEPROM image.
− SNMP ‘Get’/’Set’ Operations: The parameters 'Community String', 'Net' and
'Mask' ensure security of the SNMP 'Get'/'Set' operations. The Gigalink matches
the 'Community String' in the SNMP manager's 'Get'/'Set' request packet, and also
checks if the SNMP manager's IP address is within the range that is defined by
'Net' and 'Mask'. If any of these validations fail, the Gigalink terminal will not
respond to the request. 'Community String', 'Net' and 'Mask' can be different for
'Get' and 'Set' operations.
− Community string: The “Community String” is like a password for the SNMP
'Get'/'Set' operation. If a community string is set, then the SNMP manager needs
to provide it to the Gigalink terminal if sending 'Get'/'Set' request. When the
Gigalink terminal receives a request, it will match this string. If the match fails,
the Gigalink terminal will not send requested parameter(s) values back to the
SNMP manager on 'Get' request, and will not change its parameter values on 'Set'
request. This string must be alphanumeric and no longer than 16 characters.
− Net and Mask: These two parameters define the range of IP addresses acceptable
to the Gigalink terminal when responding to SNMP 'Get'/'Set' requests. The
format is x.x.x.x where x is a digit from 0 to 255. For example, if 'Net' is defined
as 10.0.0.0 and 'Mask' as 255.255.255.0, then the range of IP addresses the
Gigalink terminal will accept is 10.0.0.x where x = 1.254.

− Defaults: The ‘Defaults’ button is not available for users. This is used for
initializing the above parameters at the Harmonix factory.
− The ‘Threshold and Trigger’ option from ‘SNMP’ submenu of ‘Settings’ menu
opens the dialog box “Triggering Parameters and Setting Thresholds”.
“Triggering Parameters and Setting Threshold” Screen
These settings trigger parameters on/off and define the threshold range for the triggered
parameters. The Gigalink terminal monitor will send the SNMP Host/Manager an SNMP
alert trap when a trigger-enabled parameter goes beyond the set threshold range.
Checking an item’s box will activate that parameter to be monitored against threshold
ranges or an on/of condition. When the ‘Apply’ button is clicked the setting is written to
the Gigalink terminal EEPROM. The description of each parameter and their
corresponding threshold values are given below.

Triggering Parameters and Threshold Setting Dialog Box Details
•
6 Volt: A power supply voltage. Enter ‘Low’ for low threshold ranging (5.6 to 6.1), and
enter ‘High’ for high threshold ranging (6.1 to 6.5). The optimum value is 6.1 volt.
•
+15 Volt: A power supply voltage. Enter ‘Low’ for low threshold ranging (10 to 15), and
enter ‘High’ for high threshold ranging (15 to 20). The optimum value is 15.0 volt.
•
–15 Volt: A power supply voltage. Enter ‘Low’ for low threshold ranging (10 to 15), and
enter ‘High’ for high threshold ranging (15 to 20). The optimum value is 15.0 volt. ‘-15’
is only the name of this parameter, and all threshold values related to this parameter are
set positive.
•
VTune: Varactor tuning diode voltage. Sampling this voltage provides another
monitoring point for transmitter source stability. Vtune will typically fall between 4 and 7
Volts and may vary slightly during normal operation. Wide variations in varactor voltage
beyond the initial reading may indicate a tuning problem with the fundamental GUNN
diode oscillator source. The Vtune parameter does not offer a default threshold setting
option nor will it trigger an alarm trap in response to changes to this reading.
•
Gunn: The Gunn Oscillator current. Enter ‘Low’ for low threshold ranging (590 to 850),
and enter ‘High’ for high threshold ranging (850 to 1300). The optimum value is 850
milliamps.
•
Rx Power: The receive level. Enter ‘Low’ for low threshold ranging (300 to 600), and
enter ‘High’ for high threshold ranging (600 to 1000).
•
Tx Link: Transmit Link. If it is triggered on and optical circuit becomes open, SNMP
alert trap will be sent.
•
Rx Link: Receive Link. If it is triggered on and no data is coming to Gigalink from the
corresponding remote terminal, SNMP alert trap will be sent.
•
PLL, and Synthesizer: If the ‘PLL’ or ‘Synthesizer’ is not locked, one of the Gigalink
terminal’s fundamental frequency generating device is operating improperly. If these
parameters are triggered on, and an SNMP alert trap will be sent.
The ‘Defaults’ button sets all the default triggers and threshold values. After getting default
values, one still needs to press ‘Apply’ button to write the values to Gigalink.
The ‘Action’ menu contains the following commands:

The ‘Refresh’ option sends a broadcast with its own MAC address and with a command in
its data to request the content of the EEPROM image and A/D Converter values. All
connected Gigalink(s) reply with the data requested along with their MAC address. Gigamon
can receive replies from up to 8 Gigalink terminals and refreshes its data discarding any old
data of the current session if there is any unless any data was saved through the menu option
“Save Gigalink Info As” from ‘File’ menu before current ‘Refresh’ action. After receiving
the reply(s) the refresh command will open the “Refreshed Gigalink Information” dialog box.
“Refreshed Gigalink Information Screen”
The “Refreshed Gigalink Information” dialog screen is divided into 3 sections. The upper
left group shows Gigalink factory set, read-only parameters. The group “SNMP Network
Parameters” at the lower left shows the values used for SNMP connection/configuration and
can be changed by menu option ‘Settings’->’SNMP’->’Network’. The group “SNMP
Threshold Parameters” on the right shows each parameter, its values, which define threshold
condition and whether it is enabled or not.

The Refreshed Gigalink Information dialog box contains the parameter values for all the
Gigalink terminals that replied during ‘Refresh’ action, but displays values only for one
Gigalink at a time. If a different MAC address is chosen form the “MAC Address Combo
List”, the parameter values for that MAC Address will be displayed in a read-only format.
After ‘Refresh’ Gigamon displays the first Gigalink detected (topmost entry in MAC combo
list) as the currently selected Gigalink. To change parameter values for a Gigalink terminal
that is not “Currently Selected”, use the ”Select Gigalink” command.
The ‘Run’ command from the ‘Align’ submenu of ‘Action’ menu starts the ‘Runmode’
where Gigamon continually polls the currently selected Gigalink terminal and displays the
current A/D converter values and receive level until ‘Action->Align->Stop’ is chosen.
During “Runmode”, the window updates the values of Rx Power and other A/D Converter
values every 20 milliseconds.

Terminal Maintenance and Troubleshooting
Maintenance
Under normal operating conditions, installed Gigalink radio terminals require no
maintenance other than periodic inspections and a comparison of current monitored
parameters to those recorded during installation.
Under high dust or pollution conditions, it may be necessary to periodically clean the
terminal radomes. Cleaning the radome is most easily accomplished by using a dry rag or
cloth and ordinary glass cleaner. During the cleaning process care should be taken to
minimize blocking the transmission path as link loss or high BER may occur.
