Provisioning Management menu
When MCT is launched the MSS-1c configuration data is read from the NE and the
navigator shows all the MSS-1c provisioning sub-menus. If trouble occurs, verify that
the FTP Server in the NEtO Servers Manager window is on.
Figure 3
Provisioning sub-menus
Note: When MCT is launched from the 1353OMS, the management of the configuration of
the MSS-1c is done through a provisioning file that has to be uploaded/downloaded from/to
the NE with a FTP server. The first screen of the MSS-1c provisioning invites the User to do
this operation and offers different provisioning modes: "Initial configuration" mode must be
used to create a first configuration and the "reconfiguration mode" is appropriate to apply
modification on an existing configuration. Regarding the configuration of the MSS-1c itself,
the description given in the rest of this section is fully applicable.

that is without sub-menus displayed. When the button Refresh is pressed, the
messages shown hereafter will be displayed.
• Hardware type conversion: The operator saved a configuration file with a MSS1c 10 E1. Later he replaces the MSS-1c 10 E1 with a MSS-1c 16 PDH and wants
to load this saved configuration on the new MSS-1c. As the MSS-1c hardware
is different, a conversion of the data is needed to adapt the configuration to the
new MSS-1c 16E1. This message is displayed to warn the operator:
Figure 7
Hardware type conversion warning
If the operator cancels the conversion, this message is displayed, the loading
and conversion are then stopped and the data displayed in the MSS-1c screens
stay unmodified.
Figure 8
Conversion canceled
• MAC address conversion: The operator saved a configuration file on a NE. He
wants to load this configuration on another NE, with the same type of MSS-1c.
As the MAC address of the NE (used to create cross-connections) is different, a
conversion of the data is needed to adapt the configuration to the new NE. This
message is displayed to warn the operator:
Figure 9
MAC address conversion warning
If the operator cancels the conversion, this message is displayed, the loading
and conversion are stopped and the data displayed in the MSS-1c screens are
unmodified.

6. Start the WebEML following the procedure in Log in to and out of system.
Depending on the WebEML version you are using and the Software Package
version (NE release) loaded in the MPT, you can experience different situations:
− Situation 1: the main screen of the MPT opens. You need to check whether
the Software Package version must be updated. If needed, proceed as
described in the 9500 MPR Software Installation and NE Upgrade Manual.
− Situation 2: A popup message is displayed as shown in Figure 12.
Figure 12
NE Type or Release not supported
This means that the MCT/TCO could not locate a path associated with the
Software loaded in the MPT. This can be caused by an installation error.
You must use an MCT/TCO version higher or equal to the current software
release. First, upload this MCT/TCO version from the OLCS server to your
laptop and then run it. You will then face situation 1 or situation 3 in which it
will be possible to downgrade the Software in the MPT to align with the SW
Release used in the network.
− Situation 3: You are not able to click on the Show button of the NEtO and
a popup message indicating a version mismatch is displayed:
32
3DB 19289 ADAA TQZZA
Issue 01
MPT Craft Terminal User Manual
Figure 13
MSS-1c provisioning
Version mismatch
This means that the MCT/TCO version used is not compatible with the
Software loaded in the MPT. The software on the MPT is likely an earlier
release than the MCT/TCO. You must use MCT/TCO version higher or
equal to the current software release. First, upload this MCT/TCO version
from OLCS server to your laptop and then run it. You will then face situation
1 in which it will be possible to downgrade the Software in the MPT to align
with the SW Release used in the network.
Note: Nokia regularly introduces new NE release in production that may be not the one you
are using on your network.
7. In such case, press the Yes button in the Version mismatch to have access to
the Show button in the NEtO window.
8. Click on the Show button. The message in Figure 14 will be displayed.

Ethernet ports provisioning
• In the MPT Connected Through panel, select the port where the MPT is
connected to MSS-1c. This information is used to configure the radio ports used
in cross connections (TDM and VLANs).
• To configure an Electrical user port as user 1:
i. Select the Port Enabled check box
ii. Auto negotiation:
a. check the box: the port will negotiate speed and duplex mode with its
peer
b. do not check the box: speed and duplex mode are selected by the
operator (Forced mode)
Note: Forced mode setting is not recommended for a definitive configuration.
Autonegotiation should be chosen.
iii. If Auto negotiation is selected, for Speed select one or several check boxes,
the same for duplex mode
36
3DB 19289 ADAA TQZZA
Issue 01
MPT Craft Terminal User Manual
MSS-1c provisioning
iv. If Auto negotiation is not selected, for Speed select only one value, the
same for duplex mode.
v. If Auto negotiation is selected, the Flow Control can be configured.
• To configure a SyncE electrical port as user 2, proceed the same way as for user
1. In addition configure the Network synchronization.
a. Auto, if you do not use the syncE property of the port
b. SyncE IN, if you use the port as synchronization input. MSS-1c receives
clock from external equipment.
c. SyncE OUT, if you use the port as a synchronization output. MSS-1c sends
its clock to external equipment.
Note: this feature is authorized only if the port is set in Auto negotiation mode with speed
1000 Mbit/s and full duplex only.
• With SFP connected to the relevant slots, user ports 3 and 4 can be configured
in electrical or optical mode.
When the Port Enable Check box is selected, you can choose the type of SFP
in the SFP list (Disabled, Electrical, or Optical)
− In the Electrical mode, the configuration is like user 1.
− In the Optical mode, the Port configuration can be set to Auto negotiation or
not (forced mode). The speed is always 1000 Mbit/s.
The duplex mode is always Full Duplex.
Note: In optical mode, User port 4 can be used as SynchE port. It is also the case for User
port 3 only on MSS-1c 16PDH.
To perform PDH port and local IWF provisioning
1. Select MSS-1c Provisioning → PDH Port Provisioning. The Ethernet port
provisioning tab opens.
For the explanation of the traffic profiles TDM2TDM and TDM2ETH see MSS-1c
traffic profiles in the 9500 MPR Product Information Manual.
Note: The 75 ohm unbalanced impedance with BNC or 1.6/5.6 connectors. The 120 ohm
balanced impedance with other connectors.
Two types of MSS-1c are available: MSS-1c-10 E1 and MSS-1c-16 PDH ports
(E1 or T1).

3. Configure the PC network card interface. See the 9500 MPR Software
Installation and NE Upgrade Manual.
4. Start the WebEML following the procedure in Log in to and out of system.
Depending on the WebEML version you are using and the MPR-e Software
Package version (NE release) loaded in the MPR-e, you can experience
different situations:
− Situation 1: the main screen of the MPT opens. You need to check whether
the Software Package version must be updated. If needed, proceed with a
software upgrade as described in the 9500 MPR Software Installation and
NE Upgrade Manual.
− Situation 2: A popup message is displayed as shown in Figure 34.

NE Type or Release not supported
This means that the MCT/TCO could not locate a path associated with the
Software loaded in the MPT. This can be caused by an installation error.
You must use an MCT/TCO version higher or equal to the current software
release. First, upload this MCT/TCO version from the OLCS server to your
laptop and then run it. You will then face situation 1 or situation 3 in which it
will be possible to downgrade the Software in the MPT to align with the SW
Release used in the network.
− Situation 3: You are not able to click on the Show button of the NEtO and
a popup message indicating a version mismatch is displayed:
Figure 35
Version mismatch
This means that the MCT/TCO version used is not compatible with the
Software loaded in the MPT. The software on the MPT is likely an earlier
release than the MCT/TCO. You must use MCT/TCO version higher or
equal to the current software release. First, upload this MCT/TCO version
from OLCS server to your laptop and then run it. You will then face situation
1 in which it will be possible to downgrade the Software in the MPT to align
with the SW Release used in the network.
Note: Nokia regularly introduces new NE release in production that may not be the one you
are using on your network.
5. In such case, press the Yes button in the Version mismatch to have access to
the Show button in the NEtO window.
6. Click on the Show button. The message in Figure 36 will be displayed.

5.1 Purpose
This chapter provides the procedures to establish a session with the network element
(NE) and to log in and to log out a specific user to the MCT. For an overview of the
MCT interface, see the 9500 MPR Product Information Manual.
5.2 Prerequisites
The following prerequisites apply:
• The equipment to be provisioned must be installed; see the 9500 MPR
Hardware Installation and Replacement Manual.
• The MCT software must be installed; see the 9500 MPR Software Installation
and NE Upgrade Manual.
To log in to the system, the user must satisfy the following requirements:
• valid Username and current password
• The PC must be connected to the CT port of the MSS-1c or to the MPR-e
Ethernet generic device as explained in the provisioning chapters.
See the 9500 MPR Software Installation and NE Upgrade Manual for
information on copying the MCT from the software package and connecting the
PC to the MSS-1c or Ethernet generic device in order to access the MPT ODU.
Note: For MPR-e, the PC should be in the same sub-network as the default IP address of
the TMN in-band (first connection). If TMN in band is different from the Local NE IP, there
also needs to be a route on the PC with the gateway of the TMN in band.
Issue 01

85
Log in to and out of system
MPT Craft Terminal User Manual
Note: For MSS-1c, to access the NE the PC must be configured to “Get automatically an IP
address” (DHCP server) and a static route must be added using the command “route add
10.0.1.2 mask 255.255.255.255 192.168.30.1”.
If the NE IP address cannot be retrieved, it is possible to use the local IP address of the CT
port of the MSS-1c. This address doesn't need to create a static route.
Without the MPT connected to the MSS-1c, it is not possible to open the WebEML on the
CT port from MSS-1c.
If all the WebEML images/icons are missing, check that file msimg32.dll is present in
System32.

5.3 MCT Security session management
MCT will close automatically after 30 minutes of session inactivity.
This is not applicable in the following cases:
• When the 15 minutes or 24 hours Performance Monitoring is activated
(Normalized, Adaptive or QoS Ethernet)
• When the monitoring of the Power measurements or Modem measurements is
activated
After 25 minutes of idle session, a message dialog will be displayed on MCT to inform
the user about the expiration of the session.The user has 5 minutes to decide to
continue or to stop his session. Figure 53 shows the expiration message.

13 Radio configuration
13.1
Purpose
This chapter provides the procedure to configure the radio parameters.
13.2
General
The operation mode can be with Fixed Modulation (FCM) or with the Adaptive
Modulation (ACM).
Adaptive Modulation in a point-to-point system is to adjust the modulation as well as
a range of other system parameters based on the near-instantaneous channel
quality information perceived by the receiver, which is fed back to the transmitter with
the aid of a feedback channel.
The switching between the modulation schemes is hitless and maintains the same
RF channel bandwidth.
The system can operate with different types of ODUs according to the RF band and
to the channel arrangement. There are ODUs that can manage only one shifter or
several predefined shifters.
13.3
Procedure
To configure the radio
Note: 2048 QAM modulation is supported only on MPT-HCHQAM/XP-HQAM in
frequency bands up to 23 GHz and for Channel Spacing above or equal to
14 MHz.
1. From the Commissioning or Maintenance perspective, choose Configuration →

2. From the Telecommunications standard panel, select the ETSI or ANSI market.
3. The operation mode can be with Fixed Modulation (FCM) or with the Adaptive
Modulation (ACM).
a. For operation with Fixed Modulation (FCM) (Figure 86 and Figure 87)
perform the following in the Modulation panel:
i. In the Coding Modulation Type field, select Fixed (FCM).
ii. In the Channel Spacing field, select the channel spacing to be used:
ETSI: up to 56 MHz for MPT-HC/HC-HQAM/MC/XP/XP-HQAM
ANSI: up to 60 MHz for MPT-HC/XP/HC-HQAM/XP-HQAM/9558HC/
HLC
iii. For MPT-HC-HQAM only: check the MPT-HC compatibility check box
if needed. If the MPT-HC compatibility check box is checked, MPT-HC
HQAM and MPT-HC can be mixed on both sides of a radio hop.
iv. Select the Modem Profile Option: Current Mask Standard Profile or
New Mask Standard Profile
In the ETSI market: Current mask standard profile or New mask
standard profile
In the ANSI market: Choose Standard Profile
v. In the Reference Modulation field, select the Modulation scheme:
In the ETSI market:
up to 256 QAM for MPT-HC, MPT-MC, and MPT-XP
up to 2048 QAM for MPT-HC-HQAM (if the compatibility with MPT-HC
box is unchecked)
In the ANSI market:
up to 256 QAM for MPT-HC, MPT-XP, and 9558HC
up to 2048 QAM for MPT-HC- HQAM (if the compatibility with MPT-HC
box is unchecked)
vi. Based on the selected Channel Spacing and the Reference
Modulation, the relevant capacity will appear in the Net Radio Capacity
field.
b. For Operation with Adaptive Modulation (ACM) (Figure 88), perform the
following in the Modulation panel:
i. In the Coding Modulation Type field, select Adaptive (ACM).
ii. In the Channel Spacing field, select the channel spacing.

iii. For MPT-HC-HQAM only: check the MPT-HC compatibility check box
if needed. If the MPT-HC compatibility check box is checked, MPT-HC
HQAM and MPT-HC can be mixed on both sides of a radio hop.
iv. Select the Modem Profile Option:
In the ETSI market: Choose Current mask standard profile or New
mask standard profile
In the ANSI market: Choose Standard Profile
v. In the Reference Modulation field, select the reference modulation. For
MPT-HC/MC/XP this modulation scheme is the lowest one.
For MPT-HLC or MPT-HC-HQAM/XP-HQAM, the lowest modulation
can be lower than the reference modulation.
vi. In the Allowed Modulation field, select all the modulation schemes to be
used with the Adaptive Modulation. The modulation schemes (from the
lowest to the highest scheme) must be contiguous. Modulation is
limited to 256QAM for MPT-HC, MPT-MC and MPT-XP. For MPT-HC
HQAM/XP-HQAM modulation up to 2048 QAM is available if the
compatibility with MPT-HC is unchecked.
Warning: If the changes increase the current radio bandwidth, the warning message
(Figure 85) will be raised to the operator. The new setting must be validated with Nokia.

iv. Allow Rx Frequency Tuning check box this frequency can be changed in
±+5 MHz increments to implement the Exotic shifter configuration, if
required.
5. To mute the transmitter, select the Mute check box.
6. Select the Transmit Power Control Mode: RTPC or ATPC.
7. Configure RTPC settings:
a. Tx power without Adaptive Modulation
If the ATPC is disabled, the Tx Power field is available. The Tx Power range
is displayed in the screen.
In this field, enter the new value within the allowed transmitted power range.
b. Tx Power with Adaptive Modulation
You can modify only the Tx power relevant to the lowest modulation
scheme. In this field you must enter the constant power, which will be used
with the lowest modulation.
Note: The same power value will be used by the other modulation schemes.
8. Configure ATPC settings:
i. ATPC Remote RSL Threshold
The value of the low power threshold can be changed by writing the new
value in the field. When the Rx power is equal to this power the ATPC
algorithm starts to operate.
The set point of the ATPC regulation (ATPC RSL threshold) must be chosen
considering the link budget. For example if the set point is too high, the
remote transmitter will permanently remain at maximum power. It is
recommended to choose a value at least 15 dB above the 10-6 BER
threshold.
In ATPC+ACM the RSL threshold must be set correctly in order to ensure
that the maximum throughput capacity is met while ATPC is working. The
typical minimum margin compared to the highest modulation 10-6 BER
Threshold, is somewhere between 7dB (low modulation) to 11dB (high
modulation). These values are for information only and are radio
configuration dependent.
ii. Min ATPC Tx power and Max ATPC Tx power

Advanced radio configuration
14 Advanced radio configuration
14.1
Purpose
This chapter provides the procedure to configure the advanced radio parameters.
14.2
General
The Advanced Radio menu is used to specify the expected and sent identifier values
of parameters related to the link management and, if necessary, to modify them.
If the link identifier is Enabled, the following fields can be filled in:
• Tx Radio Link Identifier: This field is the link identifier entered on the transmitting
NE (1 to 255)
• Expected Rx Radio Link Identifier: This field is the link identifier expected at the
receiving NE (0 to 255).
Note: If the Expected Rx Link Identifier is "0", there is no link identifier mismatch
management.
• Packet Throughput Booster: In order to improve the use on air bandwidth, the
MPT can compress the packet applying the following principle: whenever a
packet is received with a known packet header at remote site, the MPT saves
bandwidth by not transmitting this header each time. Only some learning bytes
allow to index the corresponding known packet header.
When activated the MPT will compress, when possible, the packet to save air
bandwidth. To activate the Packet Throughput Booster, select the check box.
Note: The remote NE must have also enabled its Packet Throughput Booster feature for
decompression capabilities.
• Latency Optimization: for latency-sensitive applications, latency optimization
can be enabled to minimize latency. This is applicable to TDM and Ethernet
traffic. The latency improvement is in the range of about 0.15 ms.

Purpose
This chapter provides the procedure to configure radio encryption. This option is only
available on MPT-HC/HC-HQAM.
16.2
General
The 9500 MPR supports 256 bit AES encryption with static key. A key generation
string (Passphrase) has to be entered at both ends of the radio link to generate the
encryption/decryption key.
Since the radio encryption usage is restricted, a password is needed to have access
to this service. If you don't have it, contact your Nokia sales representative.
Note: The password is requested only at the first commissioning.

such as NEs in Single NE mode with 7705 SAR.
a. For the TMN RF over PPP, select “TMN RF PPP” (as shown in Figure 100)
b. For the In-band management, tick the “TMN RF In-Band”. Then configure
the IP address, the network mask and the VLAN ID [range 2..4080]
allocated to the TMN RF in-band interface. This IP address and the remote
NE TMN RF In-band IP address must be in the same subnet.
Figure 100
TMN RF field
Note: The TMN RF in-band Van ID must be different from the one configured for User
Ethernet TMN in-band.
You need to ensure the consistency of the TMN RF configuration at both ends of the radio
interface, otherwise the TMN RF in-band link will not set up.
4. For the MSS-1c only, in the NMS1/NMS2 fields, assign the IP parameters to the
10/100Base-T 2 Ethernet ports (if required) for NMS application.

NE neighbors configuration
21 NE neighbors configuration
21.1
Purpose
This chapter provides the procedure to configure LLDP service on the Ethernet user
port in the NE Neighbors tab.
21.2
General
The upper part of the NE Neighbors tab allows the user to enable the LLDP service
on the Ethernet user port. By default LLDP is disabled.
The lower part of the tab displays the following for MPR-e:
• The radio neighbor of the MPT. The neighbor is unique. It is discovered using an
Nokia proprietary discovery protocol. If a radio failure occurs, the shows the
current known radio neighbor until a new one is discovered.
• The LLDP neighbor of the MPT. The LLDP neighbor is also unique; see
Automatic link discovery in the 9500 MPR Product Information Manual.
However, because a neighbor may announce several management IP
addresses in its LLDP PDU, the table may contain several rows, one per IP
address. See Figure 116.
For MSS-1c the table displays the MPT's radio neighbors only: information, remote
IP and remote port; see Figure 117. There is no site name displayed for MSS-1c
neighbors. The site Name field is only used on MPR-e for LLDP.
The radio neighbor is unique. It is discovered through an Nokia proprietary radio
discovery protocol. In case of radio failure, the table shows the last known neighbor
until a new one is discovered.

25 Performance monitoring
25.1
Purpose
This chapter provides the procedures to monitor NE performance in the MCT.
25.2
General
25.2.1
Performance monitoring perspective
From the Performance Monitoring perspective, the user can monitor the
performance of the NE. The menu has the following sub-menus:
• Performance history file upload
• Normalized
• Adaptive modulation
• Ethernet QoS
• RSL history
• Monitoring (see Viewing alarms and Power and modem measurements)
25.2.1.1
Performance history file upload
This menu allows you to export a .csv file with data regarding the performance
counters. This operation is done through an FTP (by default) or SFTP session, see
Figure 145 and Figure 146.
For the QoS Ethernet Counter history and MPR-e Traffic Port Ethernet Counters file
upload the counter period duration can be adjusted from 5 to 3600 s. It can be
modified by typing the in the History Period field and applying the value.

25.2.1.2
MPT Craft Terminal User Manual
Normalized
The MPR-e supports normalized Hop PM for 1+0 configuration.
When in 1+1 HSB configuration, Link PM is also provided by the EPS active MPR-e.
The EPS standby MPR-e reports only Hop PM and no data for Link PM. Whenever
an EPS switch occurs (automatic or issued by operator), the current period is
declared suspected and PM link monitoring continues on the new EPS active MPR-e.
25.2.1.2.1
Counters thresholds
In the Counters Thresholds screen the Low Threshold and High Threshold can be
changed for each G.826 parameter (BBE, ES, SES). The high threshold will cause
the activation of a Threshold exceeded alarm during the Performance Monitoring
period and the low threshold will cause the deactivation of the same alarm.
Note: For the 24-hour report only the High Threshold can be changed.
25.2.1.2.2
15Min counters
The upper part of the screen will show the values of the current 15-min period; the
lower part will show the last elapsed 15-min period.
When a 15-min period is over, the period data is automatically reported and shown
on the lower part of the window.

25.2.1.4.1
MPT QoS ingress counters
MPT QoS Ingress counters computation is always activated. The history period can
be modified (see Performance history file upload).
The upper part of the window shows a graphical evolution of the counters.
The lower part of the window will show a table reporting the counter values when
monitoring is activated. Each time the counters are refreshed, an entry will be added
to the table.
The QoS counters are:
• Transmitted Frames
• Discarded Frames
Note: The Egress Discarded Frames counter is associated with 100Base-Tx. It has no
meaning when the MPR-e is working at 1000B-T/1000B-SX
• Transmitted Bytes
The counters are shown in the following formats:
• bar
• graphical
• tabular
Counters can be displayed for a single queue (Queue # tab) or for all the queues
(Aggregate tab).
The default span of the graphical format is 24 hours, but it can be changed.
An example of the QoS Counters screen is given in Figure 138.

Compression gain
Compression gain counters show the difference in bandwidth when Packet
Throughput Booster is enabled; see Figure 139.
With no traffic running, the gain is displayed as "--"..
The following counters are provided in the table and displayed on the graph:
• TTO: total number of octets of Ethernet frames transmitted out by the MPT radio
(TTO-C) or received as input by the port (TTO-L2 and TTO-L1).
− TTO-C: TTO after compression
− TTO-L2: TTO counted at Layer 2
− TTO-L1: TTO counted at Layer 1
• Gain: percentage increase in TTO from using compressed frames
− Gain L2: 100*(ΔTTO-L2/ΔTTO-C)
− Gain L1: 100*(ΔTTO-L1/ΔTTO-C)
If Packet Throughput Booster is not enabled, the TTO-C is equal to TTO-L2. Gain L1
is always greater than 100% regardless of whether Packet Throughput Booster is
enabled, therefore TTO-L1 is always greater than TTO-L2.

Overview
This chapter contains information and procedures to aid in restoring the equipment
to its correct operating condition after it has been determined that a problem exists.
The following warnings and cautions apply while operating, performance testing,
troubleshooting, or repairing the 9500 MPR series radios.
Danger: Short circuits in low-voltage, low-impedance dc circuits can cause severe arcing
that may result in burns or eye injury. Remove rings, watches, and other metal jewelry while
working with primary circuits.
Exercise caution to avoid shorting power input terminals.
Caution: Units with the electrostatic-sensitive (ESS) symbol contain ESS devices. Store
these units in an antistatic container when not in use, and anyone handling a unit should
observe antistatic precautions.
Refer to the Special Precautions pages in the front of the instruction book for detailed
handling information.
Note: Ensure that all antennas are correctly aligned and waveguide is in good physical
condition.
Note: Before performing procedures that might in any way affect transmission, it is

Maintenance philosophy
This section provides information and procedures for equipment maintenance down
to the Card level. Card repair is not covered in this manual.
The use of maintenance procedures in this section may result from failure of a
periodic check, an alarm indication, or unacceptable performance.
This document addresses only the 9500 MPR maintenance. For information about
Maintenance on an MPT directly connected to a 7705 SAR system, see the
7705 SAR documentation. In addition, considering the level of integration between
two systems and their joint behavior, maintenance operation must always involve
people with knowledge of both the 9500 MPR and the 7705 SAR.
27.3
Personal computer (PC)/laptop
If the MSS-1c is in use, connect the RJ45 Interface cable between craft terminal
connector on the MSS-1c and the PC.
For MPR-e, connect the PC to the FE port of the Ethernet generic device.

Alarm clearing and maintenance
Before going to site checklist
Where possible, before going to site obtain the following information:
• Does the fault require immediate attention?
• Determine who is the best-placed person to attend the fault.
• Confirm the nature and severity of the reported fault, its location, MPT type,
frequency band, high/low end MPT, capacity modulation and configuration (non
protected, protected, diversity). Ask:
− Is just one link affected, or a number of links in the same geographical area?
− Is the path down completely or is traffic passing but with a BER alarm?
− Could the fault be in the equipment connected to MPT, rather than in MPT?
Are there alarms on other, connected equipment?
− Is it a hard or intermittent fault?
− Do alarms confirm which end of an alarmed link is faulty?
• Could the weather (rain, ice, high wind, temperature) be a factor in the reported
fault?
Note: If the fault suggests a rain fade or other weather related fade condition and it matches
the prevailing weather conditions, do not take any action until the weather abates.
• Does link history suggest any fault trends?
− Does the fault history for the link indicate a likely cause?
− Is the link newly installed?
− Has there been any recent work done on the link?
• Ensure that you have with you:
− Appropriate spares. Where an equipment failure is suspected, these should
include replacement of the MSS-1c (if present) and MPT. If an MPT is
suspected then local/national climbing safety requirements must be
adhered to.
− A laptop PC loaded with craft terminal, and an Ethernet cable. If an Ethernet
connection is to be used, you need the IP address and also the addresses
for any remote sites to be accessed.
− If login security has been enabled, you need the password for the local and
also any remote sites to be accessed.
− Any special test equipment that may be needed, such as a BER tester.
− Toolkit.
− Keys for access to the site.

Warning: Before any I&C (Installation & Commissioning) for a new link or during
Maintenance with an ODU repaired by Nokia, if the MPT-MC/HC/XP is received
with the current release software and this is not the correct SW version used on
the network, the ODU must be downgraded to the correct SW Release using
MCT / TCO ≥ R5.0.0.
The correct MCT/TCO must be first uploaded from OLCS server to a laptop,
where the downgrade can be performed.
27.4.2
Network supervision troubleshooting for MSS-1c
If the following message error is raised when you start the supervision:
Figure 168
Message error
1. Check that you have added a static route (see Static route configuration).
2. Check the MSS-1c variant you are using. In case of MSS-1c 16PDH, the root
cause could be the MPT SW which is not at the minimum version required. It is
mandatory to up-grade the MPT SW. Two solutions can be used:
a. Up-grade of MPT SW using an MSS-1c tool:
In that case, the MSS-1c 16PDH is temporary replaced by a MSS-1c
(3DB18613AA) used as a tool during the time of the SW up-grade.
The procedure is as follows:
1. Replace the MSS-1c 16PDH by the MSS-1c
2. Up-grade the MPT SW to MPR version
3. Come back to the MSS-1c 16PDH
b. Up-grade of MPT SW through the MPT traffic port:
The procedure consists to connect directly the PC on the MPT electrical
traffic port as described in the MPR-e User Manual.

The PC must have a GbE interface and capability to tag VLAN. Depending
on the MPT type and the connection between MSS-1c 16PDH and MPT
(electrical or optical), additional materials may be needed as follows:
1. MPT-MC:
- a Power Injector box (3CC50129AA) must be used as a tool to merge
the data from the PC and the DC. This composite signal is sent to the
MPT-MC
- a RJ45/RJ45 cable to connect the PC to the Power injector box
2. MPT-HC/HC-HQAM:
- a Power Injector box (3CC50129AA) or MPT Extended Power Unit
(3CC50174AA) must be used as a tool to merge the data from the PC
and the DC. This composite signal is sent to the MPT--HC v2/HCHQAM
- a RJ45/RJ45 cable to connect the PC to the Power injector box
3. MPT-XP/XP-HQAM:
- an MPT Extended Power Unit (3CC50174AA) must be used as a tool
to merge the data from the PC and the DC. This composite signal is
sent to the MPT-XP/XP-HQAM
- a RJ45/RJ45 cable to connect the PC to the MPT Extended Power
Unit

PC troubleshooting
If the NE is not displayed in the NEtO screen, MCT has to be launched directly
through MctStarter.jar located under the path created by the operator during the local
copy and under
\\WebEML MPR TCO Rx.y\9500MCT_V0X.0X.XX\MctStarter.jar

27.4.4.1
MPT Craft Terminal User Manual
Check MSS-1c front-panel LED indications
These provide summary alarm indications, which can help narrow down the location
and type of failure.
27.4.4.2
Check the basics first
• For example, if multiple alarms are present, and these include power supply
voltage or hardware alarms, always check their cause before looking at resultant
down-stream path failure or path warning (signal) alarms.
• Similarly, if a path-related failure is indicated (no hardware or software alarms),
investigate the path. Go to the craft terminal History screen (15 minute view) to
check supporting data, such as low RSL and incidence of intermittent pre-failure
BER alarms, which if present are evidence of a path-related failure.

27.4.4.3
Alarm clearing and maintenance
Check if symptoms match the alarm.
Alarms reflect the alarm state, but in exceptional circumstances an alarm may be
raised because of a failure to communicate correctly with the alarm source, or a
failure in alarm management processing. Always check to see if symptoms match the
alarm, using LED indications and the craft terminal.
27.4.4.4
Check if recent work may be a cause.
Recent work at the site may be a cause or contributing factor. Check for a
configuration change, software upgrade, power recycling (reboot), or other site work:
• Many hardware alarms are only initiated as a loss-of-communications alarm
during a reboot, software upgrade, or reconfiguration. By not being able to
communicate with the MSS-1c, their settings cannot be loaded. The fault may
be at the hardware device (most likely), or communications to it.
27.4.4.5
MSS before an ODU
If there is doubt about whether a fault is in the MSS or ODU, always replace the MSS
first; it is quicker and easier.

Troubleshooting with MSS-1c electrical or optical
connection
In case of electrical connection with MPT (PFoE), there must be NO optical SFP
plugged in MPT cage port (even if no fiber connected).
In case of moving from optical to electrical connection with MPT, the MSS-1c has to
be switched off/on AFTER having unplugged the optical SFP on MPT port.

Troubleshooting path problems
A path-related problem, with the exception of interference, is characterized by traffic
being similarly affected in both directions. Generally, if you are experiencing only a
one-way problem, it is not a path problem.
Note: A path extends from the MPT antenna port to MPT antenna port.
• Normally a path problem is signaled by a reduced RSL, and depending on its
severity, a high BER.
• Only in worst case situations, such as an antenna knocked out of alignment, will
a path fail completely, and stay that way.
• For weather-related problems, such as rain or ducting, the path problem will
disappear as the weather returns to normal.
27.4.7.1
Path problems on a commissioned link
A path problem on an existing link, one that has been operating satisfactorily may be
caused by one of the following:
• Weather-related path degradation
If BER alarms are fleeting/not permanent and RSL returns to its normal,
commissioned level after the alarm is cleared, rain, diffraction, or multipath
fading is indicated. Rain fade is the likely cause of fade for links 13 GHz and
higher. Diffraction and multipath/ducting for links 11 GHz and lower. If these
alarms are persistent, there could be a problem with the link design or original
installation.
Issue 01
3DB 19289 ADAA TQZZA
239
Alarm clearing and maintenance
MPT Craft Terminal User Manual
• Changed antenna alignment or antenna feed problem
If RSLs do not return to commissioned levels after a period of exceptionally
strong winds, suspect antenna alignment. Also, check the antenna for physical
damage, such as may occur with ice-fall. For a remote-mounted MPT, check its
antenna feeder.
• New path obstruction
Where all other parameters check as normal, and the path has potential for it to
be obstructed by construction works, view/survey the path for possible new
obstructions.
• Interference from other signal sources
Interference usually affects traffic in just one direction. Unlike other path
problems, RSL is not affected. If suspected, check for new link installations at,
or in the same geographical area, as the affected site. Ultimately, a spectrum
analyzer may have to be used to confirm interference, which is not an easy task
given the need to connect directly to the antenna port, after removing the MPT.
27.4.7.2
Path problems on a new link
For a new link, potential problems can extend to also include:
• Incorrect antenna alignment
One or both antennas incorrectly aligned. Refer to the Antenna alignment
procedure in the 9500 MPR Hardware Installation and Replacement Manual.
• Mismatching antenna polarizations
Given a typical polarization discrimination of 30 dB, for most links it is not
possible to capture a signal to begin the antenna alignment process.
• Incorrect path calculations
If the RSLs are too low or too high, antenna alignment is correct, and Tx power
settings are correct, check the path calculations used to determine the link
performance. A good calculation match is ± 2 dB. Disagreements in excess of 3
dB should be investigated.
• Reflections
Reflection (path cancellation) problems may not have been picked up at the path
planning stage, particularly if the survey was a simple line-of-sight. If suspected,
resurvey the path.

Alarm clearing and maintenance
Troubleshooting configuration problems
Configuration problems should only occur during the setup of a new link, or
reconfiguration of an existing link. The more common problems may be broadly
categorized as:
• Incorrect circuit connections
No alarms are activated for incorrect circuit connections. An incorrect
assignment means the expected end-to-end circuit connectivity will not happen.
Re-check circuit assignments for all nodes carrying the lost circuit(s).
Take extra care when configuring ring circuits.
• Incorrect ID naming and commissioning
All traffic-carrying circuits must have a unique flow ID for the cross-connect
capability to operate.
• Incorrect/incompatible trib settings
Trib line interface settings incorrect, or line levels incompatible. While no alarm
activates for an incorrect setting, its effect may result in line levels being too low
(LOS alarm), or too high, resulting in a high BER.
27.4.9
Troubleshooting MSS-1c Ethernet problems
This section gives general guidance on troubleshooting problems related to the four
Ethernet ports on the MSS-1c.
The most common Ethernet problems are network and connectivity related and
therefore always check the following first:
• for User and NMS ports, verify link partner capability, provisioning, and
connection
• for Radio ports, verify the cabling between MPT and MSS-1c
In order for the green Link LED to light:
• Cable must be connected to Ethernet port
• Ethernet port must be enabled (provisioned Enabled). Applicable for User and
NMS ports
• Speed and mode must be provisioned the same as the link partner.
The yellow LED opposite the green on the connector indicates activity only. The
flashing yellow LED is not an indicator of signal type or quality.

Troubleshooting MSS-1c TMN problems
This section gives general guidance on troubleshooting TMN problems related to
NMS Ethernet ports 1 and 2 on the MSS-1c.
The most common TMN problems are network related and first alert is normally
observed by incorrect operation at the SNMP master. Always check the following
first:
• Verify master is correctly registered in NE to receive traps.
• Verify SNMP version matches system requirements
• Verify correct community string and privileges
• Verify correct network routing.
Refer to Table 17 for detail TMN network troubleshooting.
Table 17
TMN network troubleshooting for MSS-1c
Problem
Possible Cause
Possible Solution
Unusually slow communication in
radio network
1. Normal network management
traffic is saturating the
communications channel.
1. There may be too many radios
being managed within a single
region. Split the radio network
management into different regions
and backhaul the traffic for each
region through separate channels.
2. Polling radios for PM data or
missed alarms too rapidly
2. Poll the radios more slowly.
3. Multiple remote software
downloads in process
3. Download to fewer radios at a
time.
4. IP traffic other than network
management traffic being routed
through radio network
4. Configure external routers to allow
only network management related
traffic through the Management
network of the radios. Dynamic route
updates (OSPF) may attempt to
reroute high speed traffic through the
TMN network if a high speed ink
fails.
To perform control operations, the
Manager must be registered as a
craft device.
Register the Manager as a craft
device. Manager registration type
can be changed as needed to type
‘ct’ to allow control operation and
then be changed back to ‘nml’ for
normal operation.

2. Check network connectivity.
Check redundant network paths and
routing. Traceroute (tracert) is useful
for locating path or routing faults.
Unable to communicate with the
NE through the radio network

Can ‘ping’ the TMN Interface but
cannot communicate with the NE
using SNMP, or can only see a few
SNMP objects in the NE.
If using SNMPv2, using the wrong
community string.
Verify community string or

MPT-HC/XP/HC-HQAM/XP-HQAM/9558HC removal
and replacement
Disconnect the cables and connect them to the spare MPT-HC/XP/HC-HQAM/XPHQAM/9558HC.
If an MSS-1c is in use, perform the following:
1. Reconfigure the MPT by using the WebEML (menu Commissioning >
Configuration) or if a backup file is available, restore the MPT configuration
using the WebEML (menu Commissioning > Configuration > Backup/Restore).
2. Connect the WebEML to the CT port of MSS-1c and configure the PC to “Get
automatically an IP address” (because the NE is configured as DHCP Server
with default IP address 192.168.30.1 and subnet mask 255.255.255.252).
Warning: The MPT-HC can be used to replace a MPT HC-HQAM only if the MPT
HC-HQAM is working in MPT-HC Compatibility mode (see Radio configuration).
Note: The MPT-HC V2 can also be used to replace the MPT-HC V1. The 23 GHz MPT-HC
V2 is a Tx High Power version vs. MPT-HC V1. Take in account it when MPT-HC V2 is used
as spare of MPT-HC V1.

Warning: Do not use acid, alcohol, or brushes to clean the equipment because damage to
the silk-screen labeling and antistatic coating can result. Cleaning should be confined to the
removal of dust and dirt using a damp cloth.
Cleaning should normally be confined to the removal of dust and dirt using a soft
bristled (natural fiber) brush and a low velocity blower (such as a vacuum cleaner
with a plastic blower nozzle). Do not use acid or synthetic bristled brushes to clean
cards that contain electrostatic-sensitive components.
