RECOMMENDATION:
Note the color code that you enter. Ensure that you can readily associate this
color code both with the module and with the other data that you store about the
module.
Sector ID
You can optionally enter an identifier to distinguish this link.
Downlink Data
The operator specifies the percentage of the aggregate (uplink and downlink total)
throughput that is needed for the downlink. The default for this parameter is 50%.
Transmit Frame Spreading
If you select Enable, then a BHS between two BHMs can register in the assigned BHM
(not the other BHM). Canopy strongly recommends that you select this option. With this
selection, the BHM does not transmit a beacon in each frame, but rather transmits a
beacon in only pseudo-random frames in which the BHS expects the beacon. This allows
multiple BHMs to send beacons to multiple BHSs in the same range without interference.
Transmitter Output Power
Nations and regions may regulate transmitter output power. For example
◦
Both 900-MHz and 5.7-GHz modules are available as connectorized radios,
which require the operator to adjust power to ensure regulatory compliance. In
addition to setting the power in the 5.7-GHz connectorized module, the operator
must set the antenna gain/cable loss such that the module can accurately report
received power at the antenna.
◦
Legal maximum allowable transmitter output power and EIRP (Equivalent
Isotropic Radiated Power) in the 2.4-GHz frequency band varies by country and
region. The output power of Series P9 2.4-GHz modules can be adjusted to meet
these national or regional regulatory requirements.
◦
Countries and regions that permit the use of the 5.4-GHz frequency band (CEPT
member states, for example), generally require equipment using the band to
have adjustable power.
The professional installer of Canopy equipment has the responsibility to
◦
maintain awareness of applicable regulations.
◦
calculate the permissible transmitter output power for the module.
◦
confirm that the initial power setting is compliant with national or regional
regulations.
◦
confirm that the power setting is compliant following any reset of the module to
factory defaults.
For information on how to calculate the permissible transmitter output power to enter in
this parameter, see Adjusting Transmitter Output Power on Page 326.
The Radio tab also provides the following buttons.

Installation and Configuration Guide
Release 8
Community String
Specify a control string that allows Prizm or a Network Management Station (NMS) to
access the module through SNMP. No spaces are allowed in this string. The default
string is Canopy.
The Community String value is clear text and is readable by a packet monitor.
Additional security derives from the configuration of the Accessing Subnet, Trap
Address, and Permission parameters.
Accessing Subnet
Specify the addresses that are allowed to send SNMP requests to this BHM. Prizm or
the NMS has an address that is among these addresses (this subnet). You must enter
both
◦
The network IP address in the form xxx.xxx.xxx.xxx
◦
The CIDR (Classless Interdomain Routing) prefix length in the form /xx
For example
◦
the /16 in 198.32.0.0/16 specifies a subnet mask of 255.255.0.0 (the first 16 bits
in the address range are identical among all members of the subnet).
◦
192.168.102.0 specifies that any device whose IP address is in the range
192.168.102.0 to 192.168.102.254 can send SNMP requests to the BHM,
presuming that the device supplies the correct Community String value.
NOTE:
For more information on CIDR, execute an Internet search on “Classless
Interdomain Routing.”
The default treatment is to allow all networks access.
Trap Address 1 to 10
Specify ten or fewer IP addresses (xxx.xxx.xxx.xxx) to which trap information should be
sent. Trap information informs Prizm or an NMS that something has occurred. For
example, trap information is sent
◦
after a reboot of the module.
◦
when Prizm or an NMS attempts to access agent information but either
−
supplied an inappropriate community string or SNMP version number.
−
is associated with a subnet to which access is disallowed.
Trap Enable
Select either Sync Status or Session Status to enable SNMP traps. If you select
neither, then traps are disabled.
Read Permissions
Select Read Only if you wish to disallow any parameter changes by Prizm or an NMS.

Specify the type of air link security to apply to this BHM:
◦
Encryption Disabled provides no encryption on the air link. This is the default
mode.
◦
Encryption Enabled provides encryption, using a factory-programmed secret
key that is unique for each module.
NOTE:
In any BH link where encryption is enabled, the BHS briefly drops registration
and re-registers in the BHM every 24 hours to change the encryption key.
BHS Display of BHM Evaluation Data
You can use this field to suppress the display of data (Disable Display) about this BHM
on the BHM Evaluation tab of the Tools page in the BHS.
Web, Telnet, FTP Session Timeout
Enter the expiry in seconds for remote management sessions via HTTP, telnet, or ftp
access to the BHM.
IP Access Control
You can permit access to the BHM from any IP address (IP Access Filtering Disabled)
or limit it to access from only one, two, or three IP addresses that you specify (IP Access
Filtering Enabled). If you select IP Access Filtering Enabled, then you must populate
at least one of the three Allowed Source IP parameters or have no access permitted
from any IP address, including access and management by Prizm.
Allowed Source IP 1 to 3
If you selected IP Access Filtering Enabled for the IP Access Control parameter, then
you must populate at least one of the three Allowed Source IP parameters or have no
access permitted to the BHM from any IP address. You may populate as many as all
three.
If you selected IP Access Filtering Disabled for the IP Access Control parameter, then
no entries in this parameter are read, and access from all IP addresses is permitted.

Unit Settings Tab of the BHM
An example of the Unit Settings tab of the BHM is displayed in Figure 112.
Figure 112: Unit Settings tab of BHM, example
The Unit Settings tab of the BHM contains an option for how the BHM should react when
it detects a connected override plug. You may set this option as follows.
Set to Factory Defaults Upon Default Plug Detection
If Enabled is checked, then an override/default plug functions as a default plug. When
the module is rebooted with the plug inserted, it can be accessed at the IP address
169.254.1.1 and no password, and all parameter values are reset to defaults.
A subscriber, technician, or other person who gains physical access to the module and
uses an override/default plug cannot see or learn the settings that were previously
configured in it. When the module is later rebooted with no plug inserted, the module
uses the new values for any parameters that were changed and the default values for
any that were not.
If Disabled is checked, then an override/default plug functions as an override plug. When
the module is rebooted with the plug inserted, it can be accessed at the IP address
169.254.1.1 and no password, and all previously configured parameter values remain
and are displayed. A subscriber, technician, or other person who gains physical access
to the module and uses an override/default plug can see and learn the settings. When the
module is later rebooted with no plug inserted, the module uses the new values for any
parameters that were changed and the previous values for any that were not.

Draft 2 for Regulatory Review
Issue 2, December 2006
Release 8
Installation and Configuration Guide
Timing Mode
Select Timing Slave. This BH will receive sync from another source. Whenever you
toggle this parameter to Timing Slave from Timing Master, you should also do the
following:
1. Make no other changes in this or any other interface page.
2. Save this change of timing mode.
3. Reboot the BH.
RESULT: The set of interface web pages that is unique to a BHS is made available.
NOTE:
In a BHS that cannot be converted to a BHM, this parameter is not present (for
example, in a BHS with Hardware Scheduling and Series P8 hardware.)
Link Speeds
Specify the type of link speed for the Ethernet connection. The default for this parameter
is that all speeds are selected. The recommended setting is a single speed selection for
all APs, BHs, and SMs in the operator network.
Webpage Auto Update
Enter the frequency (in seconds) for the web browser to automatically refresh the webbased interface. The default setting is 0. The 0 setting causes the web-based interface to
never be automatically refreshed.
Bridge Entry Timeout
Specify the appropriate bridge timeout for correct network operation with the existing
network infrastructure. Timeout occurs when the BHM encounters no activity with the
BHS (whose MAC address is the bridge entry) within the interval that this parameter
specifies. The Bridge Entry Timeout should be a longer period than the ARP (Address
Resolution Protocol) cache timeout of the router that feeds the network.
This parameter governs the timeout interval, even if a router in the system has a longer
timeout interval. The default value of this field is 25 minutes.
CAUTION!
An inappropriately low Bridge Entry Timeout setting may lead to temporary loss
of communication with some end users.
Bridging Functionality
Select whether you want bridge table filtering active (Enable) or not (Disable) on this
BHS. Selecting Disable allows you to use redundant BHs without causing network
addressing problems. Through a spanning tree protocol, this reduces the convergence
time from 25 minutes to mere seconds. However, you should disable bridge table filtering
as only a deliberate part of your overall network design. Otherwise, disabling it allows
unwanted traffic across the wireless interface.

Select either
◦
Power Up in Aim Mode—the BHS boots in an aiming mode. When the BHS
senses an Ethernet link, this parameter is automatically reset to Power Up in
Operational Mode. When the BHS senses no Ethernet link within 15 minutes
after power up, the BHS carrier shuts off.
◦
Power Up in Operational Mode—the BHS boots in Operational mode and
attempts registration. Unlike in previous releases, this is the default selection in
Release 8.
2X Rate
See 2X Operation on Page 91.
Frame Timing Pulse Gated
If this BHS extends the sync pulse to a BHM or an AP behind it, select either
◦
Enable—If this BHS loses sync, then do not propagate a sync pulse to the BHM
or AP. This setting prevents interference in the event that the BHS loses sync.
◦
Disable—If this BHS loses sync, then propagate the sync pulse anyway to the
BHM or AP.

Figure 115: Radio tab of BHS, example
In the Radio tab of the BHS, you may set the following parameters.
Custom Radio Frequency Scan Selection List
Specify the frequency that the BHS should scan to find the BHM. The frequency band of
the BHs affects what channels you select.
IMPORTANT!
In the 2.4-GHz frequency band, the BHS can register to a BHM that transmits on
a frequency 2.5 MHz higher than the frequency that the BHS receiver locks
when the scan terminates as successful. This establishes a poor-quality link. To
prevent this, select frequencies that are at least 5 MHz apart.
In a 2.4-GHz BHS, this parameter displays all available channels, but has only three
recommended channels selected by default. See 2.4-GHz AP Cluster Recommended
Channels on Page 137.
In a 5.2- or 5.4-GHz BHS, this parameter displays only ISM frequencies. In a 5.7-GHz
BHS, this parameter displays both ISM and U-NII frequencies. If you select all
frequencies that are listed (default selections), then the module scans for a signal on any
channel. If you select only one, then the module limits the scan to that channel. Since the
frequencies that this parameter offers for each of these two bands are 5 MHz apart, a
scan of all channels does not risk establishment of a poor-quality link as in the 2.4-GHz
band. Nevertheless, this can risk establishment of a link to the wrong BHM.
A list of channels in the band is provided in Considering Frequency Band Alternatives on
Page 136.
(The selection labeled Factory requires a special software key file for implementation.)
Color Code
Specify a value from 0 to 254. For registration to occur, the color code of the BHM and
the BHS must match. On all Canopy modules, the default setting for the color code value
is 0. This value matches only the color code of 0 (not all 255 color codes).
RECOMMENDATION:
Note the color code that you enter. Ensure that you can readily associate this
color code both with the module and with the other data that you store about the
module.
Transmitter Output Power
Nations and regions may regulate transmitter output power. For example
◦
Both 900-MHz and 5.7-GHz modules are available as connectorized radios,
which require the operator to adjust power to ensure regulatory compliance. In
addition to setting the power in the 5.7-GHz connectorized module, the operator
Issue 2, December 2006

must set the antenna gain/cable loss such that the module can accurately report
received power at the antenna.
◦
Legal maximum allowable transmitter output power and EIRP (Equivalent
Isotropic Radiated Power) in the 2.4-GHz frequency band varies by country and
region. The output power of Series P9 2.4-GHz modules can be adjusted to meet
these national or regional regulatory requirements.
◦
Countries and regions that permit the use of the 5.4-GHz frequency band (CEPT
member states, for example), generally require equipment using the band to
have adjustable power.
The professional installer of Canopy equipment has the responsibility to
◦

18.6 ADJUSTING TRANSMITTER OUTPUT POWER
Authorities may require transmitter output power to be adjustable and/or lower than the
highest that a module produces. Canopy adjustable power modules include a Radio tab
parameter to reduce power to achieve compliance. If you set this parameter to lower than
the range of the hardware in a given module, the value is automatically reset to the
lowest value the hardware is capable of.
The best practice is to
326
◦
maintain awareness of applicable regulations.
◦
calculate the permissible transmitter output power for the module.
◦
confirm that the initial power setting is compliant.
Draft 2 for Regulatory Review
Issue 2, December 2006
Release 8
Installation and Configuration Guide
◦
confirm that the power setting is compliant following any reset of the module to
factory defaults.
◦
Adjust (usually reduce) transmit power so as to have a good signal at the
receiver without transmitting excesss power. Note this usually means reducing
transmit power for close-in SMs, while setting the AP to reach its most distant
SM. For BHs, this usually means reducing the power symmetrically.
IMPORTANT!
In the European Union, operators are under regulatory requirements to control
transmit power so as to enhance sharing with other band users.

RECOMMENDATION:
Use shielded cable for all Canopy infrastructure connections associated with
BHs, APs, and CMMs. The environment that these modules operate in often has
significant unknown or varying RF energy. Operator experience consistently
indicates that the additional cost of shielded cables is more than compensated
by predictable operation and reduced costs for troubleshooting and support.
19.1 PDA ACCESS TO CANOPY MODULES
For RF spectrum analysis or module aiming on a roof or tower, a personal digital
assistant (PDA) is easier to carry than, and as convenient to use as, a notebook
computer. The PDA is convenient to use because no scrolling is required to view
◦
spectrum analysis results.
◦
RSSI and jitter.
◦
master module evaluation data.
◦
information that identifies the module, software, and firmware.
To access this data in a format the fits a 320 x 240 pixel PDA screen, the PDA must have
all of the following:
◦
a Compact Flash card slot.
◦
any of several Compact Flash wired Ethernet cards.
◦
a wired Ethernet connection to the module.
◦
a browser directed to http://ModuleIPAddress/pda.html.

To install the Canopy AP, perform the following steps.
Procedure 19: Installing the AP
334
Draft 2 for Regulatory Review
Issue 2, December 2006
Release 8
Installation and Configuration Guide
1. Begin with the AP in the powered-down state.
2. Choose the best mounting location for your particular application. Modules need
not be mounted next to each other. They can be distributed throughout a given
site. However, the 60° offset must be maintained. Mounting can be done with
stainless steel hose clamps or another equivalent fastener.
3. Align the AP as follows:
a. Move the module to where the link will be unobstructed by the radio horizon
and no objects penetrate the Fresnel zone. (The Canopy System Calculator
page AntennaElevationCalcPage.xls automatically calculates the minimum
antenna elevation that is required to extend the radio horizon to the other end
of the link. The Canopy System Calculator page FresnelZoneCalcPage.xls
automatically calculates the Fresnel zone clearance that is required between
the visual line of sight and the top of a high-elevation object.)
b. Use a local map, compass, and/or GPS device as needed to determine the
direction that one or more APs require to each cover the intended 60° sector.
c.
Apply the appropriate degree of downward tilt. (The Canopy System
Calculator page DowntiltCalcPage.xls automatically calculates the angle of
antenna downward tilt that is required.)
d. Ensure that the nearest and furthest SMs that must register to this AP are
within the beam coverage area. (The Canopy System Calculator page
BeamwidthRadiiCalcPage.xls automatically calculates the radii of the beam
coverage area.)
4. Using stainless steel hose clamps or equivalent fasteners, lock the AP in the
proper direction and downward tilt.
5. Remove the base cover of the AP. (See Figure 52 on Page 178.)
6. Attach the cables to the AP.
(See Procedure 5 on Page 184.)
NOTE: When power is applied to a Canopy module or the unit is reset on the web-based
interface, the module requires approximately 25 seconds to boot. During this interval,
self-tests and other diagnostics are being performed. See Table 44 on Page 179.
=========================== end of procedure ===========================
19.3 INSTALLING A CONNECTORIZED FLAT PANEL ANTENNA
To install a connectorized flat panel antenna to a mast or structure, follow instructions
that the manufacturer provides. Install the antenna safely and securely, consistent with
industry practices.
The Universal Mounting Bracket available from Motorola (Part Number SMMB-1 and
consisting of a mounting bracket and L-shaped aluminum tube) holds one Canopy
module, but cannot hold both the module and a connectorized antenna. The SMMB-2 is a
heavy duty bracket that can hold both a 900-MHz module and its connectorized antenna.
See Module Support Brackets on Page 59.

WARNING!
Although the output of the power converter is 24 V, the 100-W power rating
classifies the converter as a Class 2 electric device. For this reason, whenever
you work on power in the CMMmicro, you must first disconnect the DC converter
from the AC power source.
Perform the following procedure to install the provided power supply.
Procedure 25: Installing the Power Supply for the CMMmicro
1. Connect the 6-ft (2-m) AC power cord to the power converter (but not yet to an
AC receptacle).
2. Select the length of power cord as follows:
a. If either mounting the unit inside with the power converter or outside within 9
ft (2.8 m) of the power converter, select the 10-ft (3-m) DC power cord (rated
for outdoor use).
b. If mounting the unit outside and further than 9 ft (2.8 m) from the power
converter, ensure that this additional length of cord is either UV-resistant or
shielded from UV rays.
◦
use a terminal block, connector, or splice to add the additional length.
◦
protect the terminal block, connector, or splice (as inside a weatherized
enclosure, for example).

19.7 INSTALLING AN SM
Installing a Canopy SM consists of two procedures:
◦
Physically installing the SM on a residence or other location and performing a
course alignment using the alignment tone (Procedure 28).
◦
Verifying the AP to SM link and finalizing alignment using review of power level
and jitter, link tests, and review of registration and session counts (Procedure 29
on Page 349).
Procedure 28: Installing the SM
1. Choose the best mounting location for the SM.
2. Select the type of mounting hardware appropriate for this location. (For mounting
2.4, 5.2, 5.4, and 5.7 GHz SMs, Motorola offers the SMMB-1 mounting bracket.
For mounting 900 MHz SMs, Motorola offers the SMMB-2 mounting bracket.)
3. Remove the base cover of the SM. (See Figure 52 on Page 178.)
4. Terminate the UV outside grade Category 5 Ethernet cable with an RJ-45
connector, and connect the cable to the SM. (See Procedure 8 on Page 192.)
5. Optionally, attach the SM to the arm of the Canopy Passive Reflector dish
assembly as shown in Figure 133.
RECOMMENDATION:
A reflector in this instance reduces the beamwidth to reduce
interference. The arm is molded to receive and properly aim the
module relative to the aim of the dish. Use stainless steel hose
clamps for the attachment.

KEY TO CALLOUTS
Holes—for mounting the Surge Suppressor to a flat surface
(such as an outside wall). The distance between centers is 4.25
inches (108 mm).
RJ-45 connectors—One side (neither side is better than the
other for this purpose) connects to the Canopy product (AP,
SM, BHM, BHS, or cluster management module). The other
connects to the AC adaptor’s Ethernet connector.
Ground post—use heavy gauge (10 AWG or 6 mm2) copper
wire for connection. Refer to local electrical codes for exact
specifications.
Ground Cable Opening—route the 10 AWG (6 mm2) ground
cable through this opening.
CAT-5 Cable Knockouts—route the two CAT-5 cables through
these openings, or alternatively through the Conduit
Knockouts.
Conduit Knockouts—on the back of the case, near the bottom.
Available for installations where cable is routed through
building conduit.
Figure 135: Internal view of Canopy 300SS Surge Suppressor
8. With the cable openings facing downward, mount the 300SS to the outside of the
subscriber premises, as close to the point where the Ethernet cable penetrates
the residence or building as possible, and as close to the grounding system
(Protective Earth) as possible.
9. Using diagonal cutters or long nose pliers, remove the knockouts that cover the
cable openings to the 300SS.
10. Connect an Ethernet cable from the power adapter (located inside the residence
or building, outward through the building penetration) to either RJ-45 port of the
300SS.
11. Connect another Ethernet cable from the other RJ-45 port of the 300SS to the
Ethernet port of the SM.
12. Refer to Grounding SMs on Page 172.

13. Wrap an AWG 10 (or 6mm ) copper wire around the Ground post of the 300SS.
14. Tighten the Ground post locking nut in the 300SS onto the copper wire.
15. Securely connect the copper wire to the grounding system (Protective Earth)
according to applicable regulations.
16. Connect a ground wire to the 300SS.
17. Replace the cover of the 300SS surge suppressor.
18. For coarse alignment of the SM, use the Audible Alignment Tone feature as
follows:
a. Set the 2X Rate parameter in the SM to Disable.
b. At the SM, connect the RJ-11 6-pin connector of the Alignment Tool Headset
to the RJ-11 utility port of the SM.
Alternatively, instead of using the Alignment Tool Headset, use an earpiece
or small battery-powered speaker connected to Pin 5 (alignment tone output)
and Pin 6 (ground) of an RJ-11 connector.
c.
Listen to the alignment tone for
◦
pitch, which indicates greater signal power (RSSI/dBm) by higher
pitch.
◦
volume, which indicates better signal quality (lower jitter) by higher
volume.
Figure 136: Audible Alignment Tone kit, including headset and connecting
cable
d. Adjust the module slightly until you hear the highest pitch and highest
volume.
e. If the Configuration web page of the SM contains a 2X Rate parameter, set it
back to Enable.
19. When you have achieved the best signal (highest pitch, loudest volume), lock the
SM in place with the mounting hardware.
=========================== end of procedure ===========================
19.8 VERIFYING AN AP-SM LINK
To verify the AP-SM link after the SM has been installed, perform the following steps.
Procedure 29: Verifying performance for an AP-SM link
Issue 2, December 2006
Draft 2 for Regulatory Review
349
Installation and Configuration Guide
Release 8
1. Using a computer (laptop, desktop, PDA) connected to the SM, open a browser
and access the SM using the default IP address of http://169.254.1.1 (or the IP
address configured in the SM, if one has been configured.)
2. On the General Status tab of the Home page in the SM (shown in Figure 66 on
Page 198), look for Power Level and Jitter.
IMPORTANT: The received Power Level is shown in dBm and should be
maximized. Jitter should be minimized. However, better/lower jitter should be
favored over better/higher dBm. For example, if coarse alignment gives an SM
a power level of −75 dBm and a jitter measurement of 5, and further refining
the alignment drops the power level to −78 dBm and the jitter to 2 or 3, the latter
would be better, with the following caveats:
◦
When the receiving link is operating at 1X, the Jitter scale is 0 to 15 with
desired jitter between 0 and 4.
◦
When the receiving link is operating at 2X, the Jitter scale is 0 to 15 with
desired jitter between 0 and 9.
NOTE:
For historical reasons, RSSI is also shown and is the unitless
measure of power. The best practice is to use Power Level and
ignore RSSI, which implies more accuracy and precision than is
inherent in the measurement.
3. Fine-adjust the SM mounting, if needed, to improve Jitter or Power Level.
4. Click the Link Capacity Test tab of the Tools web page in the SM.
NOTE: Use of this tool is described under Using the Link Capacity Test Tool (All)
on Page 434.
5. Perform several link tests of 10-second duration as follows:
a. Type into the Duration field how long (in seconds) the RF link should be
tested.
b. Leave the Packet Length field (when present) set to the default of 1522
bytes or type into that field the packet length at which you want the test
conducted.
c.
Leave the Number of Packets field set to 0 (to flood the link).
d. Click the Start Test button.
e. View the results of the test.
6. If these link tests fail to consistently show 90% or greater efficiency in 1X
operation or 50 to 60% efficiency in 2X, troubleshoot the link, using the data as
follows:
◦
If the downlink is consistently 90% efficient, but the uplink is only 40%, this
indicates trouble for the SM transmitting to the AP. Have link tests performed
for nearby SMs. If their results are similar, investigate a possible source of
interference local at the AP.
◦
If the uplink is consistently 90% efficient, but the downlink is only 40%, this
indicates trouble for the AP transmitting to the SM. Investigate a possible
source of interference near the SM.
If these link tests consistently show 90% or greater efficiency in 1X operation, or
50 to 60% efficiency in 2X operation, in both uplink and downlink, continue this
procedure.
