Preparing for configuration and alignment
This section describes the checks to be performed before proceeding with unit configuration and
antenna alignment.
Safety precautions
All national and local safety standards must be followed while configuring the units and aligning
the antennas.
Warning
Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to
radiate RF energy as soon as they are powered up. Respect the safety standards
defined in Compliance with safety standards on page 4-22, in particular the minimum
separation distances.
Observe the following guidelines:
•
Never work in front of the antenna when the ODU is powered.
•
Always power down the PSU before connecting or disconnecting the drop cable
from the PSU, ODU or LPU.
Warning
When installing the PTP 700 ATEX/HAZLOC product variants in hazardous locations,
follow the instructions contained in the PTP 700 Series Hazardous Location Guide
(supplied in box with the products), in addition to the instructions in this user guide.
Regulatory compliance
All applicable radio regulations must be followed while configuring the units and aligning the
antennas. For more information, refer to Compliance with radio regulations on page 4-28.
Page 6-2
Chapter 6: Configuration and alignment
Preparing for configuration and alignment
Caution
If the system designer has provided a list of channels to be barred for TDWR radar
avoidance, the affected channels must be barred before the units are allowed to
radiate on site, otherwise the regulations will be infringed. To bar these channels,
follow the procedure Barring channels on page 7-39.
Attention
Si le concepteur du système a fourni une liste de canaux à interdire pour éviter les
radars TDWR, les cannaux concernées doivent être interdits avant que les unités sont
autorisées à émettre sur le site, sinon la réglementation peut être enfreinte. Pour
bloquer ces canaux, suivez la procédure Barring channels page 7-39.
Selecting configuration options
Use the installation report to determine which configuration options are required. Refer to
LINKPlanner on page 3-25.
Generating license keys
To obtain License Keys for capabilities that are not factory-installed, proceed as follows:
Identify and purchase access keys for the required capability upgrades by referring to ODU
capability upgrades on page 2-8.
Obtain the MAC Address of the ODU (it is on the System Status page).
Go to the Cambium Support web page (see Contacting Cambium Networks on page 1) and
navigate to the Cambium Networks License Key Generator.
Enter the MAC Address and Access Key.
Select the country of operation for the link. The list of available countries depends on the
regional variant; not all countries are available in all variants. The generated license will
automatically include all of the regulatory bands approved for that country.
Select any other required capabilities from those that are available.
Submit the web form. Cambium will send the License Key by email.
Use the Software License Key page to configure the ODU with newlicense keys (Software License
Key page on page 6-11).

Attribute
Meaning
Lowest TDM Modulation
Mode
Only displayed when TDM Interface is set to E1 or T1.
The lowest modulation mode at which TDM data can be sent. If
the link cannot sustain TDM data in this mode then the effective
lowest modulation mode may differ.
In conjunction with the LINKPlanner tool, this setting may be used
to optimize the latency for links which operate in consistently high
modulation modes. High data rate links are able to support lower
latencies.
Configuring port allocations
The Interface Configuration page controls the allocation of the Main PSU Port, Aux Port and SFP
Port to the Data Service, Second Data Service, Management Service and Local Management
Service.
PTP 700 supports exactly one instance of the Data Service, and this service is always mapped to
one of the three wired ports. It is not possible to operate a link without any port selected to the
Data Service.
PTP 700 supports zero or one instances of the optional Second Data Service. The Second Data
Service is enabled by a license key field, and is automatically licensed in any unit with a Full
capacity license. The Second Data Service can be disabled or mapped to any available port, except
for the port already allocated to the Data Service.
PTP 700 supports zero or one instances of the optional Management Service. The Management
Service can be used to access the management agent at the local unit. If the wireless link is
established, the Management Service can also be used to access the management agent at the
remote unit and other devices connected in the remote management network. The Management
Service can be mapped to a port that is already used for the Data Service or Second Data Service
to provide In-Band Management. Alternatively, the Management Service can be allocated to a
dedicated port to provide Out-of-Band Management.
PTP 700 also supports an optional Local Management Service, providing a connection from a
wired port to the local management agent. Any port not already selected is available for selection
to the Local Management Service. The Local Management Service does not connect across the
wireless link.
The PTP 700 must always be manageable through one of three ports. Therefore it is not possible to
disable the Management Service unless at least one port is allocated to the Local Management
Service.

Warning
When installing the PTP 700 ATEX/HAZLOC product variants in hazardous locations,
follow the instructions contained in the PTP 700 Series Hazardous Location Guide
(supplied in box with the products), in addition to the instructions in this user guide.
Caution
The lower center frequency attribute must be configured to the same value for both
the Master and Slave, otherwise the wireless link will fail to establish. The only way to
recover from this situation is to modify the Lower Center Frequency attributes so that
they are identical on both the master and slave units.
Note
When configuring a linked pair of units, use the Master Slave Mode to ensure that one
unit is Master and the other is Slave.
Table 118 Wireless Configuration attributes
Attribute
Meaning
Master Slave Mode
Master: The unit controls the point-to-point link and its maintenance. On
startup, the Master transmits until a link with the Slave is made.
Slave: The unit listens for its peer and only transmits when the peer has
been identified.
Access Method
ODUs must be configured in pairs before a link can be established. Access
Method determines how paired ODUs will recognize each other.
Link Access: Each ODU must be configured with Target MAC Address
equal to the MAC Address of the other unit.
Link Name Access: Both ODUs must be configured with the same Link
Name.
Group Access: Only displayed when a Group Access license key has been
generated (Generating license keys on page 6-3) and submitted (Software
License Key page on page 6-11). Both ODUs must be configured with the
same Group ID attributes.
Target MAC Address
Only displayed when Access Method is set to Link Access. This is the
MAC Address of the peer unit that will be at the other end of the wireless
link. This is used by the system to ensure the unit establishes a wireless
link to the correct peer. The MAC Address can be found embedded within
the serial number of the unit. The last six characters of the serial number
are the last three bytes of the unit’s MAC address.
Link Name
Only displayed when Access Method is set to Link Name Access.
Link Name may consist of letters (A-Z and a-z), numbers (0-9), spaces, and
the following special characters: (),-.,:<=>[]_{}
Link Name must be same at both ends and different to site name.
Page 6-22
Chapter 6: Configuration and alignment
Installation menu
Attribute
Meaning
Group Id
Only displayed when Access Method is set to Group Access. A link can
only be established between units that have identical Group IDs.
Dual Payload
Disabled: The link maximizes robustness against fading and interference.
Enabled: The link attempts to reach maximum throughput at the expense
of robustness against fading and interference.
Max Receive
Modulation Mode
The maximum mode the unit will use as its adaptive modulation. By
default the Max Receive Modulation Mode is the highest mode available.
For minimum error rates, set the maximum modulation mode to the
minimum necessary to carry the required traffic.
Lowest Data
Modulation Mode
The lowest modulation mode that must be achieved before the link is
allowed to bridge customer data Ethernet frames. This does not affect the
bridging of management data: if out-of-band remote management is
enabled, this will continue regardless of modulation mode.
Lowest Second Data
Modulation Mode
The lowest modulation mode that must be achieved before the link is
allowed to bridge Ethernet frames in the Second Data Service. This
attribute is displayed when the Second Data Service is enabled.
Link Mode
Optimization
IP Traffic: The link is optimized for IP traffic to provide the maximum
possible link capacity.
TDM Traffic: The link is optimized for TDM traffic to provide the lowest
possible latency. This is the only available setting when TDM is enabled
(Interface Configuration page on page 6-14).
TDD
Synchronization
Mode
Disabled: The link does not employ TDD synchronization.
Enabled: The link employs TDD synchronization. This is configured in the
Installation Wizard; see TDD synchronization page (optional) on page 627. For a basic description, see TDD synchronization on page 1-18.
When TDD Synchronization Mode is set to Enabled, the following
restrictions apply: Ranging Mode and Target Range are disabled, and Link
Symmetry is limited to 1 to 1.
Regulatory Band
The regulatory band selected from the list in the license key.
Channel Bandwidth
Bandwidth of the transmit and receive radio channels.
Page 6-23
Chapter 6: Configuration and alignment
Installation menu
Attribute
Meaning
Link Symmetry
Only displayed when Master Slave Mode is set to Master.
Adaptive: Allows link symmetry to vary dynamically in response to
offered traffic load. This is not supported in the following cases:
•
Where radar avoidance is mandated in the region.
•
Link Mode Optimization is set to TDM Traffic.
“5 to 1”, “3 to 1, “2 to 1”, “1 to 1”, “1 to 2”, “1 to 3” or “1 to 5”: There is
a fixed division between transmit and receive time in the TDD frame of
the master ODU. The first number in the ratio represents the time allowed
for the transmit direction and the second number represents the time
allowed for the receive direction. The appropriate matching Link
Symmetry is set at the slave ODU automatically. For example, if Link
Symmetry is set to “2 to 1” at the master ODU, then the slave ODU will
be set automatically as “1 to 2”. In this example, the master-slave
direction has double the capacity of the slave-master direction.
When TDM is enabled (Interface Configuration page on page 6-14), Link
Symmetry is limited to “1 to 1”.

Meaning
Default Raster
This is only displayed when Spectrum Management Control is set to
Fixed Frequency. Limits frequency selection to the unit’s default raster
setting.
Fixed Tx Frequency,
Fixed Rx Frequency
This is only displayed when Spectrum Management Control is set to
Fixed Frequency. The settings must be compatible at each end of the link.
Once configured, the spectrum management software will not attempt to
move the wireless link to a channel with lower co-channel or adjacent
channel interference. Therefore this mode of operation is only
recommended for deployments where the installer has a good
understanding of the prevailing interference environment.
Tx Color Code, Rx
Color Code
Tx Color Code and Rx Color Code may be used to minimize interference
in a dense network of synchronized PTP 700 units where some of the
units are operating on the same frequency. When this type of network is
designed, the Color Code values are normally specified in the link
planning report. In all other cases, Cambium Networks recommend that
Tx Color Code and Rx Color Code are left at the default value of A.
The value of Tx Color Code MUST always match the value of Rx Color
Code at the other end of the link.
Antenna Gain
Only displayed when the ODU is connectorized.
Gain of the remote antenna.
Cable Loss

Auto..: During alignment, the wireless units use algorithms to calculate
link range. To implement automatic ranging, select a value that
corresponds to the estimated maximum range of the link:
Auto 0 to 40 km (0 to 25 miles).
Auto 0 to 100km (0 to 62 miles).
Auto 0 to 200km (0 to 125 miles).
Target Range: During alignment, the wireless units use the approximate
link distance (entered in Target Range) to calculate link range. The main
advantage of Target Range mode is that it reduces the time taken by the
units to range.
If preferred, range functions can be configured to operate in miles, as
described in Webpage Properties page on page 6-68.
Target Range
Only available when Ranging Mode is set to Target Range.

Caution
Auto-negotiation and forced Ethernet configuration:
•
To operate an Ethernet link at a fixed speed, set Auto Negotiation to Enabled and
limit Auto Neg Advertisement to the desired speed. If constrained auto-negotiation
fails, set Auto Negotiation to Disabled (forced Ethernet configuration) as a last
resort.
•
Both ends of an Ethernet link must be configured identically, because forced and
auto-negotiation are not compatible: a mixed configuration will cause a duplex
mismatch, resulting in greatly reduced data capacity.
•
The Auto Neg Advertisement or Forced Configuration data rates must be within the
capability of the Ethernet link partner, otherwise loss of service will occur.
Note
When TDM is enabled (Interface Configuration page on page 6-14), the following
restrictions are automatically applied:
•
Main PSU Port Auto Negotiation is set to Enabled.
•
Main PSU Port Auto Neg Advertisement is set to 1000 Mbps Full Duplex.

Aligning antennas
Aligning antennas
This section describes how to align the antennas in a PTP 700 link, use the web interface to assist
with alignment, and check wireless performance after alignment.
Before performing this task, check that hardware installation is complete (apart from the network
connections) at both the Master and Slave sites.
Starting up the units
Use this procedure to connect one of the units to a management PC and start up both units.
Procedure:
Select the unit from which this process is to be controlled; either Master or Slave. This is the
“local” unit.
Check that the management PC is connected to the local unit, powered up and logged on as
described in Connecting to the unit on page 6-4.
Power up the remote unit.
Log into the local unit as described in Logging into the web interface on page 6-6.
Checking that the units are armed
Use this procedure to confirm that the units are in the armed state, ready for alignment.
In the armed state, the modulation mode is fixed at BPSK 0.63 Single, the TDD frame duration is
extended to allow the link to acquire at unknown range, and the transmit power is automatically
adjusted for optimum operation.
Procedure:
•
Select menu option Home. The System Summary page is displayed.
•
Check that the Install Arm State is set to Armed.
•
If the units are not armed, execute the installation wizard as described in Installation menu on
page 6-9.
Page 6-108
Chapter 6: Configuration and alignment
Aligning antennas
Aligning antennas
Use this procedure to align linked antennas (master and slave), whether integrated or
connectorized. The goal of antenna alignment is to find the center of the main beam. This is done
by adjusting the antennas while monitoring the receive signal level.
Preparation:
Ensure that the following parameters are available:
•
Location of both sites (latitude and longitude).
•
Bearing to the other end of the link for both sites.
•
Prediction of receive signal level for both ends of the link.
•
Prediction of link loss.
LINKPlanner provides all of these parameters in the form of an installation report.
If a connectorized ODU is installed at either site with two separate antennas for spatial diversity,
refer to Aligning separate antennas for spatial diversity on page 6-110 before starting alignment.
Note
For improved radio performance, mount the integrated ODU at 45 degrees to the
vertical; this ensures that side-lobe levels are minimized for interference transmitted or
received at zero elevation.
To achieve best results, make small incremental changes to elevation and azimuth.
Caution
The action of tightening the mounting bolts can alter antenna alignment. This can be
helpful when fine-tuning alignment, but it can also lead to misalignment. To prevent
misalignment, continue to monitor receive signal level during final tightening of the
bolts.
Procedure:
At each end of the link, adjust the antenna to point at the other end of the link. This should be
done with the aid of a compass.
Without moving the master antenna, adjust the elevation and azimuth of the slave antenna to
achieve the highest receive signal level using one of the following methods:
•
ODU installation tones on page 6-111
•
Graphical Install page on page 6-113
Without moving the Slave antenna, adjust the elevation and azimuth of the Master antenna to
achieve the highest receive signal level (using one of the above methods).
Repeat steps 2 and 3 as necessary to fine-tune the alignment to find the center of the beam.
Page 6-109
Chapter 6: Configuration and alignment
Aligning antennas
When the antennas have been aligned on the center of the beam, verify that the receive level
is within the predicted range (from the installation report). If this is not the case, go back to
step 2.
The current value of receive level can be verified by using the graphical installation method
(see Graphical Install page on page 6-113) or by selecting menu option Status and monitoring
the Receive Power attribute on the System Status page.
If after repeated attempts to align, the receive level still does not lie within the predicted
range, this may be because the data provided to the prediction tool (such as LINKPlanner) is
inaccurate. For example estimates of path obstructions, antenna heights or site locations may
be inaccurate. Check this data and update the prediction as necessary.
Once the antennas have been aligned correctly, tighten the integrated ODU (or connectorized
antenna) mountings. To ensure that the action of tightening does not alter antenna alignment,
continue to monitor received signal level.
Aligning separate antennas for spatial diversity
Use this procedure if a connectorized ODU is installed at either site with two separate antennas for
spatial diversity.
Procedure:
Connect the horizontal polarization antenna to the ODU, disconnect the vertical polarization
antenna, then perform Aligning antennas on page 6-109.
Connect the vertical polarization antenna to the ODU, disconnect the horizontal polarization
antenna, then perform Aligning antennas on page 6-109.
Re-connect the horizontal polarization antennas. The received signal level should increase.
Weatherproof the antenna connections at the “H” and “V” interfaces of the ODUs, as
described in Weatherproofing an N type connector on page 5-60.

Aligning antennas
ODU installation tones
This is the first of two methods that may be used to monitor receive signal level during antenna
alignment.
The ODU emits audible tones during installation to assist with alignment. The pitch of the
alignment tone is proportional to the received power of the wireless signals. Adjust the alignment
of the unit in both azimuth and elevation until the highest pitch tone is achieved.
Note
When using ODU installation tones to align connectorized antennas, it may not be
possible to hear the tones. To overcome this problem, either use an assistant, or use a
stethoscope to give a longer reach.
The tones and their meanings are described in Table 152. In each of the states detailed in the table,
align the unit to give the highest pitch tone. The term “wanted signal” refers to that of the peer
unit being installed.

Caution
If, when in the Synchronized or Registered state, the tone varies wildly, there may be
interference or a fast fading link. Installing in this situation may not give a reliable link.
Investigate the cause of the problem.
Page 6-111
Chapter 6: Configuration and alignment
Aligning antennas
During alignment, the installation tones should exhibit the following behavior:
•
Band scan: When first started up and from time to time, the Master unit will carry out a band
scan to determine which channels are not in use. During this time, between 10 and 15 seconds,
the Master unit will not transmit and as a consequence of this neither will the Slave unit.
During this time the installation tone on the master unit will drop back to the band scan state,
and the Slave unit will drop back to the Scanning state with the pitch of the tone set to the
background noise level. Alignment of the unit should cease during this time.
•
Radar detection: If the unit is operating where mandatory radar avoidance algorithms are
implemented, the ranging behavior may be affected. The Master has to monitor the initially
chosen channel for 60 seconds to make sure it is clear of radar signals before transmitting. If a
radar signal is detected during any of the installation phases, a further compulsory 60 seconds
channel scan will take place as the master unit attempts to locate a new channel that is free of
radar interference.
•
Ranging: The PTP 700 Series does not require the user to enter the link range. The Master unit
typically takes less than 60 seconds to determine the length of the link being installed. The
Master unit will remain in the Scanning state until the range of the link has been established.
The Master unit will only move to the Synchronized state when the range of the link has been
established.
The Slave unit does not have a ranging process. The slave unit will change to the
Synchronized state as soon as the wanted signal is demodulated.
•
Retrying same channel: If, at the end of the ranging period, the Registered state is not achieved
due to interference or other reasons, the Master unit will retry twice more on the same channel
before moving to another available channel. Should this occur it may take a number of
minutes to establish a link in the Registered state.

Connecting to the network
Use this procedure to complete and test network connections.
Procedure:
If a management PC is connected directly to the PTP 700, disconnect it.
Confirm that all ODU Ethernet interface cables (PSU, SFP and Aux) are connected to the
correct network terminating equipment or devices.
If Main PSU Port Allocation is set to Disabled in the LAN Configuration page), it is not
necessary to connect the PSU LAN port to network terminating equipment.
Test that the unit is reachable from the network management system by opening the web
interface to the management agent, or by requesting ICMP echo response packets using the
Ping application. For in-band management, test that both units are reachable from one PC.
If the network management system is remote from the sites, either ask co-workers at the
management center to perform this test, or use remote login to the management system.
Test the data network for correct operation across the wireless link. This may be by
requesting ICMP echo response packets between hosts in the connected network segments,
or by some more structured use of network testing tools.
Monitor the Ethernet ports and wireless link to confirm that they are running normally. For
instructions, see System Summary page on page 7-2 and System Status page on page 7-3.

System summary and status
Attribute
Meaning
Link Loss
The maximum, mean, minimum and latest measurements of Link Loss
(dB). See System histograms on page 7-47. The link loss is the total
attenuation of the wireless signal between the two point-to-point units.
The link loss calculation is:
Pll = PTx − PRx + gTx + g Rx − cTx − cRx
Where:
Pll
= Link Loss (dB)
PTx
= Transmit power of the remote wireless unit (dBm)
PRx
= Received signal power at the local unit (dBm)
g Tx , g R x
= Antenna gain at the remote and local units respectively
(dBi). This is the gain of the integrated or connectorized antenna.
cTx , cRx = Cable loss at the remote and local units respectively (dB). It
is RF cable loss which connects ODU to Connectorized antenna.
For connectorized ODUs, the link loss calculation is modified to allow for
the increased antenna gains at each end of the link.
Transmit Data Rate
The maximum, mean, minimum and latest measurements of Transmit
Data Rate (Mbps). See System histograms on page 7-47.
Receive Data Rate

Link Capacity
Variant
Indicates whether the installed license key is Lite or Full.
When a link is established, this attribute shows the lower of the license
keys at each end. For example, if this end is Full and the other end is Lite,
it shows “Lite”. To see the installed key, go to the Installation Wizard.
Link Capacity
The maximum aggregate data rate capacity available for user traffic,
assuming the units have been connected using Gigabit Ethernet. The link
capacity is variable and depends on the prevailing wireless conditions as
well as the distance (range) between the two wireless units.

Max Modulation Mode
The maximum modulation mode has been capped by
the user and the link is operating at this cap.
Restricted Because
Installation Is Armed
The Installation Wizard has been run and the unit is
armed, forcing the link to operate in the lowest
modulation mode. To remove this restriction, re-run the
Installation Wizard to disarm the unit.
Restricted Because Of Byte
Errors On The Wireless
Link
The receiver has detected data errors on the radio and
reduced the modulation mode accordingly. The radio
may achieve a higher modulation mode as shown by the
vector error, but there is some other error source,
probably RF interference.
Restricted Because Channel
Change Is In Progress
This is a transient event where the modulation mode is
temporarily reduced during a channel change.
Limited By The Wireless
Conditions
The radio is running at the maximum achievable
modulation mode given the current wireless conditions
shown by the vector error. The radio is capable of
reaching a higher modulation mode if wireless
conditions (vector error) improve.

•
“Disabled”: The wireless will transition to the faster Dual Payload
modes as soon as the conditions are appropriate.
TDM Latency
The end-to-end latency of the TDM service between TDM ports at the
NIDUs (µs).
TDM Channel

No Signal (Local)
No TDM data is being received at the TDM port on the local NIDU.
No Signal (Remote)
No TDM data is being received at the corresponding TDM port on
the remote NIDU.
No Signal (Local
and Remote)
No TDM data is being received at the associated TDM ports on
local and remote NIDUs.
No Signal (Local
and Remote Timing)
No TDM data is being received at the TDM port on the local NIDU.
TDM data is being received at the TDM port on the remote NIDU.
The modulation mode of the link is too low to support bridging of
TDM data in the remote to local direction, but the transmit clock at
TDM port of the local NIDU is synchronised to the clock received at
the TDM port on the remote NIDU.
Remote Timing
TDM data is being received at the TDM port on the local and
remote NIDUs. The modulation mode of the link is too low to
support bridging of TDM data in either direction. The transmit
clocks at the TDM ports on local and remote NIDUs are
synchronized to the clocks received at the TDM ports on
(respectively) the remote and local NIDUs.
Disabled
The TDM link is not established. This may be because the wireless
link is down, or because the TDM service is acquiring
synchronization.

Alarms, alerts and messages
This section describes how to use alarms, alerts and syslog messages to monitor the status of a
PTP 700 link.
Alarms
Whenever system alarms are outstanding, a yellow warning triangle is displayed on the navigation
bar. The warning triangle is visible from all web pages.
Procedure:
•
Click the warning triangle (or menu option Home) to return to the System Summary page and
view the alarms. If the warning triangle disappears when it is clicked, it indicates that the
outstanding alarms have been cleared.
The example in Figure 189 shows the warning triangle in the navigation bar and an alarm
displayed in the System Summary page. The alarms are defined in Table 167.
A change of state in most alarms generates an SNMP trap or an SMTP email alert.

Alarms, alerts and messages
Table 167 System alarms
Alarm
Meaning
Aux Port Configuration Mismatch
Ethernet fragments (runt packets) have been detected
when the Aux port is in full duplex. This indicates an autonegotiation or forced configuration mismatch.
Aux Port Disabled Warning
The Aux port link has been administratively disabled via
the SNMP Interface.
Aux Port PoE Output Status
The Aux port link is down. The most likely cause is that the
unit has no Ethernet cable plugged into its Aux port.
Aux Port Status
The Aux port link is down. The most likely cause is that the
unit has no Ethernet cable plugged into its Aux port.
Cable Diagnostics Warning
“Test In Progress“ means that the Cable Diagnostics
test has been initiated on one or more ports and is in
progress.
Capacity Variant Mismatch
The link ends are different capability variants, for example,
one is Full and the other is Med.
Data Bridging Status
This alarm depends on Lowest Data Modulation Mode.
“Disabled” means that the link has stopped bridging
Ethernet frames because the Lowest Data Modulation
Mode is not being achieved or because the wireless link is
down.
Second Data Bridging Status
This alarm depends on Lowest Second Data Modulation
Mode.
“Disabled” means that the link has stopped bridging
Ethernet frames because the Lowest Second Data
Modulation Mode is not being achieved or because the
wireless link is down.
Install Status
Signaling was received with the wrong MAC address. It is
very unusual to detect this, because units with wrongly
configured Target MAC Address will normally fail to
establish a wireless link. However, rare circumstances may
establish a partial wireless link and detect this situation.
Install Arm State
A wireless unit is in installation mode. After installation,
the wireless unit should be disarmed. This will increase the
data-carrying capacity and stop the installation tone
generator. The wireless link is disarmed from the
“Installation” process, see Disarming the units on page 6114.
Page 7-18
Chapter 7: Operation
Alarms, alerts and messages
Alarm
Meaning
Incompatible Regulatory Bands
The two linked units have different Regulatory Bands. To
clear this alarm, obtain and install license keys for the
correct country and select the same Regulatory Band at
each end of the link.
Incompatible Master and Slave
The master and slave ends of the wireless link are different
hardware products, or have different software versions. It
is very unusual to detect this because incompatible units
will normally fail to establish a wireless link. However,
some combinations may establish a partial wireless link
and detect this situation.
Link Mode Optimization
Mismatch
The Master and Slave ODUs are configured to use different
link mode optimization methods (one is set to IP and the
other TDM).
Main PSU Port Configuration
Mismatch
Ethernet fragments (runt packets) have been detected
when the PSU port is in full duplex. This indicates an autonegotiation or forced configuration mismatch.
Main PSU Port Disabled Warning
The PSU port link has been administratively disabled via
the SNMP Interface.
Main PSU Port Status
The PSU port link is down. The most likely cause is that the
unit has no Ethernet cable plugged into its Aux port.
NIDU LAN Port Status
The Ethernet link between the NIDU (LAN port) and the
Ethernet network terminating equipment is not
established.
No Wireless Channel Available
Spectrum Management was unable to locate a suitable
wireless channel to operate on.
Port Allocation Mismatch
The local and remote ODUs have different services
configured.The following alarms are raised on the port
configuration mismatch -
Regulatory Band
•
Mismatch in Second Data Service: The Second Data
Service is configured at the local unit but it is not
configured at the remote unit or vice versa.
•
Mismatch in Out of Band Remote Management
Service: The Out of Band Management Service is
configured at the local unit but it is not configured at
the remote unit or vice versa.
The installed license key contains an invalid Regulatory
Band. The wireless unit is prohibited from operating
outside the regulated limits.
Page 7-19
Chapter 7: Operation
Alarms, alerts and messages
Alarm
Meaning
Remaining Full Capacity Time
Trial
Time remaining on the full capability trial period. Activated
when seven days or less of the trial period remain.
Remote Transparent Clock
Compatibility
The local and remote units have different IEEE 1588
transparent clock configurations. Both units must have the
same configuration for the feature to work correctly.
SFP Error
A non-OK value indicates that the SFP link is down. There
are two possible causes:
•
Either: the fiber link has been installed but disabled
(because the license key does not include SFP support),
•
Or: the SFP link could not be established even though
an SFP carrier was detected (due perhaps to a cabling
fault or the link is disabled at the link partner).
SFP Port Configuration Mismatch
Ethernet fragments (runt packets) have been detected
when the SFP port is in full duplex. This indicates an autonegotiation or forced configuration mismatch.
SFP Port Disabled Warning
The SFP port link has been administratively disabled via
the SNMP Interface.
SFP Port Status
The SFP port link is down. The most likely cause is that the
unit has no Ethernet cable plugged into its SFP port.
SNTP Synchronization failed
SNTP has been enabled but the unit is unable to
synchronize with the specified SNTP server.
Sync E tracking state
The state of the Synchronous Ethernet feature, if there is a
problem.
Syslog Client Enabled/Disabled
Warning
The local syslog client has been enabled or disabled.
Syslog Enabled/ Disabled
Warning
The local log of event messages has been enabled or
disabled.
Syslog Local Nearly Full
The local log of event messages is nearly full.
Syslog Local Wrapped
The local log of event messages is full and is now being
overwritten by new messages.
TDM Channel Status n
The Ethernet link between the NIDU (E1/T1 port “n”) and
the local TDM transceiver is not established.
TDM Channel Loopback n
TDM channel “n” is currently undergoing a loopback test.

This section describes how to use the Spectrum Expert page to monitor the radio spectrum usage
of the PTP 700 link.
Note
Internet Explorer versions up to and including IE8 do not support the HTTP features
used in the Spectrum Expert page.
Menu option: System > Spectrum Expert
This page is used to view and configure spectrum usage.
The Spectrum Expert page displays the following plots:
•
The Local Receive Spectrum, and
•
The Peer Receive Spectrum.
The Spectrum Expert page has two display modes:
•
Standard Display mode – The ‘Standard’ Display mode is the mode which displays only the
operational subband channels (shown in Figure 191). In this mode, the Extended Spectrum
Scanning attribute could be Enabled but the Extended display box could be un-checked.
It has further two types of plot:
•
Standard Display mode without realtime line
Standard Display mode with realtime line
Extended Display mode – The ‘Extended’ Display Mode shows the entire DSO Full Band range
of channels along with highlighted operational channels (shown in Figure 192). In this mode,
the Extended Spectrum Scanning attribute is Enabled.
This mode also has two types of plot:
Extended Display mode without realtime line
Extended Display mode with realtime line
The Extended display mode selection checkbox appears when the Extended Spectrum Scanning
attribute is set to Enabled.
See Interpreting the receive spectrum plot on page 7-33 for details on the how to interpret these
plots.

Spectrum Management Settings
All spectrum management configuration changes are applied at the master ODU only. These
changes are then sent from the master to the slave, so that both master and slave keep identical
copies of spectrum management configuration. It is therefore possible to swap master and slave
roles on an active PTP 700 link without modifying Spectrum Management configuration.
The default channelization can be modified by varying the lower center frequency attribute in the
installation wizard, as described in Wireless Configuration page on page 6-21.
Note
Before attempting to improve the performance of the spectrum management
algorithm by changing the default configuration, consult the Cambium Point-to-Point
distributor or one of the system field support engineers.
Procedure:
•
Review the configuration attributes (Table 170)
•
Update the attributes as required. At the slave unit, only Page Refresh Period can be updated.
•
To save changes, click Submit configuration changes.

This control is available in the Spectrum Expert page only.
Extended Spectrum
Scanning
Enabled: Enables scanning of entire DSO full band channels.
Disabled: Only the operational subband channels are scanned.
This control is available in the Spectrum Expert page only.
Hopping Margin
Uses this margin when making a channel hop decision. If the
interference level of the target channel is lower than that of the active
channel by at least the Hopping Margin, the link will hop to the target
channel. The default setting is 3 dB in non-radar regions, or 10 dB in
radar regions.
Asymmetric DSO
Only displayed in non-radar regions when DSO is enabled. The
default configuration of symmetric operation constrains the link to
operate symmetrically, using the same transmit and receive channels.
When in symmetric mode the slave unit will always follow the
master. If the master moves to a new channel the slave will hop to
the same channel. When the Point-to-Point link is configured as an
asymmetric link both the master and slave are free to select the best
channel from their own set of local interference metrics.
Spectrum
Management Control
Only displayed in radar regions. The options are DFS and DFS with
DSO.
Hopping Period
The Spectrum Management algorithm evaluates the metrics every
“Hopping Period” seconds (180 seconds by default) looking for a
channel with lower levels of interference. If a better channel is
located, Spectrum Management performs an automated channel hop.
If SNMP or SMTP alerts are enabled an SNMP TRAP or an email alert
is sent warning the system administrator of the channel change.
Hopping Counter (not
configurable)
This is used to record the number of channel hops. The number in the
(+) brackets indicates the number of channel changes since the last
screen refresh.
Interference Threshold
Spectrum Management uses the interference threshold to perform
instantaneous channel hops. If the measured interference on a
channel exceeds the specified threshold, then DSO will instruct the
wireless to immediately move to a better channel. If a better channel
cannot be found the PTP 700 Series will continue to use the current
active channel. (Default –85 dBm).

X axis and Y axis
The X-axis shows a stylized view of the selectable wireless channels. Note that the distance
between adjacent channels may be smaller than the channel bandwidth. If this is the case,
adjacent channels overlap. Channels are displayed separately for clarity. The axis is labeled using
the channel center frequencies in MHz. The Y-axis shows the interference power levels from –100
to –40 dBm.
Channel states
The active channel (Channel 9 in Figure 191) is always marked using solid green on the Spectrum
Expert page. The width of the hatching is directly proportional the channel bandwidth or spectral
occupancy of the channel.
The individual channel metrics are displayed using a colored bar and an “I” bar. The colored bar

•
Mean: The mean of a set of values recorded at one second intervals over the last hour.
•
Min: The minimum value measured over the last hour.
•
Latest: The latest value measured.
The values are calculated over the time that has elapsed since the link was established or since the

Table 175 System Histogram attributes in the System Statistics page
Attribute
Meaning
Transmit Power
The transmit power histogram, calculated over a one hour period.
Receive Power
The receive power histogram, calculated over a one hour period.
Vector Error
The vector error measurement compares (over a one hour period) the
received signal IQ modulation characteristics to an ideal signal to determine
the composite vector error magnitude.
Link Loss
Link loss calculated (over a one hour period) as follows:
Peer_Tx_Power (dBm) – Local_Rx_Power (dBm) + 2 x Antenna_Pattern (dBi)
Signal Strength
Ratio
The Signal Strength Ratio (calculated over a one hour period) is:
Power received by the vertical antenna input (dB) ÷
Power received by the horizontal antenna input (dB)
This ratio is presented as: max, mean, min, and latest. The max, min and
latest are true instantaneous measurements; the mean is the mean of a set of
one second means.
Signal Strength Ratio is an aid to debugging a link. If it has a large positive or
negative value then investigate the following potential problems:
•
An antenna coaxial lead may be disconnected.
•
When spatial diversity is employed, the antenna with the lower value may
be pointing in the wrong direction.
•
When a dual polar antenna is deployed, the antenna may be directed
using a side lobe rather than the main lobe.
When there is a reflection from water on the link and spatial diversity is
employed, then one expects large, slow swings in Signal Strength Ratio.
This indicates the antenna system is doing exactly as intended.
Transmit,
Receive and
Aggregate Data
Rates
The data rates in the transmit direction, the receive direction and in both
directions, expressed in Mbps (max, mean, min, and latest). The max, min
and latest are true instantaneous measurements. The mean is the mean of a
set of one second means.

Cable Diagnostics
Cable Diagnostics
This section describes how to diagnose cable faults.
The Cable Diagnostics feature may be used to test Ethernet cables connected to the Main PSU port
and the Aux port. The feature uses Time Domain Reflectometry (TDR) technology to test individual
twisted pairs in the cable, to identify open circuit and short circuit faults, and indicate the
approximate location of the fault:
•
Open circuit – An open circuit is detected when the impedance is greater than 300 ohms.
•
Short circuit – A short circuit is detected when the impedance is less than 33 ohms.
•
Approximate location of the fault - The fault location is reported as a distance from the ODU
along the cable, and is accurate to +/- 2 meters (6.5 feet).
Note
•
The cable diagnostics results are provided only as a guide.
•
The feature reliably detects all open circuit and short circuit faults in cable pairs,
but it is not possible to reliably detect short circuit faults between wires in different
cable pairs. Except for that specific circumstance, an OK result for all pairs means
the cable is good.
•
The presence of LPUs can affect the accuracy and reliability of the results.
Before initiating the test, confirm that all outdoor drop cables (that is those that connect the ODU
to equipment inside the building) are specified as supported, as defined in Outdoor copper Cat5e
Ethernet cable on page 2-35.
Test scenarios
The Cable Diagnostics test may be performed in following scenarios:
Scenarios
Actions
Main PSU port “Down”
Check for physical Ethernet cable connectivity between Power over
Ethernet (PoE) and Customer Data Network (or LAN).
If the cable connectivity is OK, Perform Cable Diagnostics test.
Aux port “Down”
Check for physical Ethernet cable connectivity between ODU and
Customer Data Network or Management Agent.
If the cable connectivity is OK, Perform Cable Diagnostics test.
Main PSU or Aux port is
“Up” but the Ethernet
speed is noticed slow
There is a possibility that one or more cable pairs have intermittent
contact with the RJ45 connector pin. This could result in intermittent
communication errors.
Page 8-2
Chapter 8: Troubleshooting
Cable Diagnostics
Follow procedure Ethernet packet test.
If Ethernet Rx Crc and Align counter is greater than ten (>10),
Perform Cable Diagnostics test.
If Packet Error Rate is greater than 1 in 1 million, Perform Cable
Diagnostics test.
If Number of lost packets are less than two (<2) after performing
Test ping packet loss, perform Cable Diagnostics test.
Otherwise check the ODU’s parameter configurations.
Cable Diagnostics test
Menu option: System > Cable Diagnostics
The Cable Diagnostics feature determines a fault in a cable and its approximate location based on
Time Domain Reflectometry (TDR).
When the test is initiated for the selected port(s), the ODU sends a known signal (+1V) over the
twisted pair cable. The transmitted signal will travel down the cable until it reflects off a fault. The
magnitude of the reflection and the time it takes for the reflection to come back can be used to
calculate the distance to the fault on the cable. For example, a +1V reflection will indicate an open
close to the PHY and a -1V reflection will indicate a short close to the PHY.
Based on the returned signal, the radio identifies the cable status and estimates the distance of the
fault. The result of the cable test will be displayed.
The cable diagnostics test can be carried out for Main PSU and AUX ports. This test is not
supported for SFP port.
Caution
•
On the Main PSU port, the presence of LPUs can affect the accuracy of the cable
diagnostics results for some cable configurations. When a fault is detected, the
feature reports the distance corresponding to the final TDR signal reflection. In
configurations where there is a short cable from the ODU to the first LPU (< 2m),
and a moderately long cable to the second LPU (30m), the final TDR signal
reflection may come from one of the LPUs itself, rather than the fault. For
example, a fault in the first short cable may be reported at or near the second LPU.
•
On the Aux port, the presence of LPUs can affect the reliability of the cable
diagnostics results for many cable configurations. Frequently, open circuit faults
may be reported when the cable is OK, and fault distances may be reported
corresponding to the LPU locations. Cable diagnostics tests on the Aux port
should be repeated a number of times to establish a pattern.

Testing link end hardware
Testing link end hardware
This section describes how to test the link end hardware when it fails on startup or during
operation.
Before testing link end hardware, confirm that all outdoor drop cables, that is those that connect
the ODU to equipment inside the building, are of the supported type, as defined in Outdoor copper
Cat5e Ethernet cable on page 2-35.
AC+DC Enhanced power injector LED sequence
For the AC+DC Enhanced power injector, the expected power-up LED sequence is:
•
The Power (green) LED illuminates steadily.
•
After about 45 seconds, the Ethernet (yellow) LED blinks slowly 10 times.
•
The Ethernet (yellow) LED illuminates steadily, then blinks randomly to show Ethernet activity.
If this sequence does not occur, take appropriate action depending on the LED states:
•
Power LED is off on page 8-7
•
Power LED is blinking on page 8-7
•
Ethernet LED did not blink 10 times on page 8-8
•
Ethernet LED blinks ten times then stays off on page 8-8
•
Ethernet LED blinks irregularly on page 8-9 (for example a short blink followed by a long blink)
•
Power LED is on, Ethernet LED blinks randomly on page 8-9
If a fault is suspected in the ODU-PSU drop cable, perform Test resistance in the drop cable on
page 5-23.
Power LED is off
Meaning: Either the PSU is not receiving power from the AC/DC outlet, or there is a wiring fault in
the ODU cable.
Action: Remove the ODU cable from the PSU and observe the effect on the Power LED:
•
If the Power LED does not illuminate, confirm that the mains power supply is working, for
example, check the plug and fuse (if fitted). If the power supply is working, report a suspected
PSU fault to Cambium Networks.
•
If the Power LED does illuminate, perform Test resistance in the drop cable on page 5-23.
Power LED is blinking
Meaning: The PSU is sensing there is an overload on the ODU port; this could be caused by a
wiring error on the drop cable or a faulty ODU.
Page 8-7
Chapter 8: Troubleshooting
Testing link end hardware
Action: Remove the ODU cable from the PSU. Check that pins 4&5 and 7&8 are not crossed with
pins 1&2 and 3&6. Check that the resistance between pins 1&8 is greater than 100K ohms. If either
check fails, replace or repair the ODU cable.
Ethernet LED did not blink 10 times
Meaning: The ODU flashes the LED on the AC+DC Enhanced Power Injector 10 times to show that
the ODU is powered and booted correctly.
Action:
Remove the ODU cable from the PSU. Examine it for signs of damage. Check that the ODU
cable resistances are correct, as specified in Test resistance in the drop cable on page 5-23. If
the ODU cable is suspect, replace it.
Use the LPU (if installed) to check that power is available on the cable to the ODU. Access the
connections by rotating the LPU lid as shown (slacken the lid nut but do not remove it):
Check that test point P1 on the LPU PCB corresponds to pin 1 on the RJ45. Repeat for points
P2 to P8. This test is only valid if both the PSU and the ODU are disconnected.
Reconnect the ODU cable to the PSU.
Check that the PWR LED near the top right of the LPU PCB is illuminated to indicate power in
the Ethernet cable.
If any test fails, replace or repair the cable that connects the PSU to the LPU or ODU.
Ethernet LED blinks ten times then stays off
Meaning: There is no Ethernet traffic between the PSU and ODU.
Action: The fault may be in the LAN or ODU cable:
Page 8-8
Chapter 8: Troubleshooting
Testing link end hardware
•
Confirm that Ethernet traffic is connected to the AC+DC injector LAN port, confirm the cable is
not faulty, replace if necessary.
•
If the LAN connection to the AC+DC power injector is working, check the drop cable is correctly
wired using a suitable cable tester. Repeat the drop cable tests on page Test resistance in the
drop cable on page 5-23.
Ethernet LED blinks irregularly
Meaning: If the Ethernet LED blinks irregularly, for example two rapid blinks followed by a longer
gap, this indicates that the ODU has booted in recovery mode. The causes may be: installation
wiring, or a corrupt ODU software load, or sufficient time has not been allowed between a repeat
power up.
Action: Refer to Recovery mode on page 7-63.
Power LED is on, Ethernet LED blinks randomly
Meaning: Both LEDs are in their normal states, implying that the PSU is receiving power from the
AC/DC outlet and there is normal Ethernet traffic between the PSU and ODU.
Action: If, in spite of this, a fault is suspected in the link end hardware:
•
If the Ethernet connection to the network is only 100BASE-TX, when 1000BASE-T is expected:
remove the ODU cable from the PSU, examine it, and check that the wiring to pins 4&5 and
7&8 is correct and not crossed.
•
Perform Ethernet packet test on page 8-10.

Test Ethernet packet errors reported by ODU
Log into the unit and click Administration, Statistics, Detailed Counters. Click Reset System
Counters at the bottom of the page and wait until the Ethernet Rx Packets counter has reached 1
million (the count will only update when the page is refreshed. If the counter does not increment
or increments too slowly, because for example the PTP 700 is newly installed and there is no
offered Ethernet traffic, then abandon this procedure and consider using the procedure Test ping
packet loss on page 8-11.
Read the Ethernet Rx Crc And Align counter. The test has passed if this is less than 10.
Test Ethernet packet errors reported by managed switch or router
If the ODU is connected to a managed Ethernet switch or router, it may be possible to monitor the
error rate of Ethernet packets. Please refer to the user guide of the managed network equipment.
The test has passed if the rate of packet errors reported by the managed Ethernet switch or router
is less than 10 in 1 million packets.
Test ping packet loss
Using a computer, it is possible to generate and monitor packets lost between the PSU and the
ODU. This can be achieved by executing the Command Prompt application which is supplied as
standard with Windows and MAC operating systems.
Caution
This procedure disrupt network traffic carried by the PTP 700 under test:
Procedure:
Ensure that the IP address of the computer is configured appropriately for connection to
the PTP 700 under test, and does not clash with other devices connected to the network.
If the PSU is connected to an Ethernet switch or router then connect the computer to a spare
port, if available.
If it is not possible to connect the computer to a spare port of an Ethernet switch or router,
then the PSU will need to be disconnected from the network in order to execute this test:
•
Disconnect the PSU from the network.
•
Connect the computer directly to the LAN port of the PSU.
On the computer, open the Command Prompt application.
Page 8-11
Chapter 8: Troubleshooting
Testing link end hardware
Send 1000 ping packets of length 1500 bytes. The process will take 1000 seconds, which is
approximately 17 minutes.
If the computer is running a Windows operating system, this is achieved by typing (for an IPv6
address, use the ping6 command):
ping –n 1000 –l 1500 
where  is the IP address of the PTP 700 ODU under test.
If the computer is running a MAC operating system, this is achieved by typing:
ping –c 1000 –s 1492 
where  is the IP address of the PTP 700 ODU under test.
Record how many Ping packets have been lost. This is reported by Command Prompt on
completion of the test.
The test has passed if the number of lost packets is less than 2.

Testing the radio link
Testing the radio link
This section describes how to test the link when there is no radio communication, when it is
unreliable, when the data throughput rate is too low, or when a unit is causing radio or TV
interference. It may be necessary to test the units at both ends of the link.
No activity
If there is no wireless activity, proceed as follows:
Check for Alarm conditions on Home page.
Check that the software at each end of the link is the same version.
Check that the Target Mac address is correctly configured at each end of the link.
Check Range.
Check Tx Power.
Check License keys to ensure that both units are the same product variant.
Check Master/Slave status for each unit and ensure that one unit is Master and the other unit
is slave.
Check that the link is not obstructed or the ODU misaligned.
Check the DFS page at each end of the link and establish that there is a quiet wireless channel
to use.
10
If there are no faults found in the configuration and there is absolutely no wireless signal,
retry the installation procedure.
11
If this does not work then report a suspected ODU fault to Cambium Networks.
Some activity
If there is some activity but the link is unreliable or does not achieve the data rates required,
proceed as follows:
Check that the interference has not increased using the DSO measurements.
If a quieter channel is available check that it is not barred.
Check that the path loss is low enough for the communication rates required.
Check that the ODU has not become misaligned.

Meaning: The PTP-SYNC unit is not powered up.
Action: Ensure that there is a cable connection between the PSU ODU interface and the PIDU IN
interface of the PTP-SYNC unit. Confirm that the PSU is powered up.
STATUS LED is on steady
Meaning: There is power but no satellite lock. This probably indicates that a 1PPS synchronization
pulse is not detected by the PTP-SYNC unit.
Action: Depending on system configuration, take one of the following actions:
•
System using a GPS receiver module - Ensure that there is a cable connection between the
PTP-SYNC GPS/SYNC IN interface and the LPU, also that there is a cable connection between
the LPU and the GPS receiver module. Check that the GPS receiver module has an
uninterrupted view of the sky.
•
System using an alternative 1PPS timing source - Ensure that there is a cable connection
between the PTP-SYNC GPS/SYNC IN or 1PPS IN interface and the 1PPS timing source.
•
On cluster slave units – Ensure that there is a cable connection between the slave GPS/SYNC
IN interface and the SYNC OUT interface of the preceding unit in the chain.
STATUS LED double-blinks
Meaning: There may be a fault in the GPS/SYNC IN or 1PPS IN cables.
Action: Check the GPS wiring in accordance with Table 39.

Testing a TDM link
Performing a TDM loopback test
The loopback test allows a TDM data stream to be looped back at the copper or wireless interface.
A typical T1 or E1 installation test includes a copper loopback on the local unit followed by a
wireless loopback on the remote unit.
Note
The TDM Configuration page is only available when the TDM interface is enabled and
the unit is rebooted (Interface Configuration page on page 6-14).
Procedure:
•
Select menu option System > Configuration > TDM Configuration (Figure 145).
•
Set the TDM Channel Loopback n attribute (where “n” is in the range 1 to 8) to Copper or
Wireless (Table 132).
•
Click Submit Updated TDM Configuration.
•
Perform loopback tests. The System Summary page displays alarms indicating the presence of
loopbacks on each affected TDM channel (Alarms on page 7-17).
•
Set the TDM Channel Loopback n attribute (where “n” is in the range 1 to 8) to None (Table
132).
•
Click Submit Updated TDM Configuration.
Checking for 1000BASE-T operation
If the ODU port has negotiated a link at 100BASE-T, the NIDU will not send or receive TDM data
and will not bridge customer data traffic. Check that the Ethernet drop cable between the ODU and
the PSU, and the network cable between the PSU and the NIDU have successfully negotiated
operation at 1000BASE-T. On the System Status page, review Main PSU Port Speed and Duplex
(Figure 184) and confirm that it is set to 1000 Mbps Full Duplex.
