Chapter 1
Overview
Functions of Fault Management
The fault management system collects fault information from all the NEs in the managed
network in near real-time, such as boards, links, databases, and servers, and then
displays the collected fault information in the format of alarm or notification. The fault
management system helps the system administrator quickly locate and resolve faults
in the managed network. It also provides telecom operators, network management
departments, and equipment vendors with correct and timely alarm data to ensure stable
network operations.
Fault Indication
The fault management system indicates a fault or event occurring in the network in the
form of alarm or notification.
l
l
A fault is indicated in the form of alarm when it persists and affects the reliability
and services of the system. An alarm will be cleared only after the fault is resolved.
Immediate troubleshooting is required when alarms occur.
A notification indicates a non-repeatable or instantaneous fault or event in the
system, for example, board reset and signaling overload. Such a fault or event is
normally caused by a sudden environment change or other accidental factors. No
special handling is required because the fault or event causing a notification can be
automatically handled by the system. However, a frequently-reported notification
requires troubleshooting.
Alarm Format
The alarms defined for the ZXG10 iBSCare provided with the information such as property
and possible causes. For details, refer to Table 1-1.

Item
Description
Severity
There are four alarm severity levels, which are indicated in descending order
of severity as Critical, Major, Minor, and Warning.
l
Critical: indicates a fault that causes failures of system operations or
service capabilities. Immediate troubleshooting is required when a critical
alarm is reported.
l
Major: indicates a fault that seriously impacts proper system operations or
reduces service capabilities. Clearing the fault to restore the system as
soon as possible is required when a major alarm occurs.
l
Minor: indicates a fault that slightly influences proper system operations or
reduces service capabilities. Proper measures should be taken to clear
the fault in a timely manner and prevent the occurrence of more severe
alarms when a major alarm occurs.
l
Warning: indicates a fault that has a potential or gradual impact on proper
system operations or service capabilities. Warning messages need to
be analyzed and proper measures should be taken to clear the fault in a
timely manner and avoid more severe alarms.
l
Unknown: indicates a fault that severity is defined by users.
The impact degree described in the definition of alarm severity refers to the
impact on a single index, for example, reliability or security. Once the impact
on any index reaches the specified threshold, the severity level of the alarm
can be roughly determined. If an alarm has an impact on multiple indices, its
severity level should be escalated accordingly.
Type
Based on the triggering condition and system impact, alarms can be classified
into the following five types:
l
Equipment alarm: related with equipment hardware faults.
l
Communication alarm: related with information transmission faults (ITU-T
Recommendation X.733).
l
Processing error alarm: related with software or processing faults (defined
in ITU-T Recommendation X.733).
l
Environment alarm: related with the environment where the equipment is
located (defined in ITU-T Recommendation X.733).
l
QoS alarm: related with equipment operation performance or indexes.
Alarm Description
Describes how the alarm is triggered.
Alarm Cause
Provides probable alarm causes to help users troubleshoot, find preventive
measures, and restore the system to normal state in a timely manner.
Impact
Provides the consequence of each alarm and the impact on the system and
services.

Description
Action
Provides the troubleshooting steps and suggestions.
During the alarm handling process, the following tips needs your attention:
l
After recording the fault information, O&M personnel needs to handle the
fault step by step as suggested. If there is no otherwise specified and the
fault is solved (that is, alarm is cleared), the alarm handling process ends.
If the fault persists, go to the next step.
l
If fault cannot be removed, contact the local ZTE office.
Notification Format
The notifications defined for the ZXG10 iBSC are provided with the information such as
property and possible causes. For details, refer to Table 1-2.
Table 1-2 Notification Format Description

Description
Code
Uniquely identifies a notification.
Name
Summarizes the event information, such as the cause and phenomenon.
Severity
There are two alarm severity levels, which are indicated in descending order of
severity as Major, and Minor.
l
Major: indicates a fault that seriously impacts proper system operations or
reduces service capabilities. Clearing the fault to restore the system as
soon as possible is required when a major alarm occurs.
l
Minor: indicates a fault that slightly influences proper system operations or
reduces service capabilities. Proper measures should be taken to clear
the fault in a timely manner and prevent the occurrence of more severe
alarms when a major alarm occurs.
The impact degree described in the definition of notification severity refers
to the impact on a single index, for example, reliability or security. Once the
impact on any index reaches the specified threshold, the severity level of the
notification can be roughly determined. If a notification has an impact on
multiple indices, its severity level should be escalated accordingly.
Type
The notification types are the same as the alarm types.
Notification

Impact
1. All services on the equipment are down if the alarm is caused by Cause 1 or Cause 2.
2. All services on the line card are affected if the alarm is caused by Cause 3. If the service is not
configured in master/slave or load sharing mode, all services on the line card will be down. If the
service is configured in master/slave or load sharing mode, all services on the line card will soon be
restored after being down temporarily.
Action
1. Check whether PSN board reboots repeatedly. If yes, Check whether the PSN board type
configured is consistent with the PSN board type actually in use.
If inconsistent (for example, the configured board type is PSN4V and the board type actually in use is
PSN8V), modify board type configuration or replace the board actually in use to keep consistency
between board configuration and the board in use.
If consistent, PSN board hardware might be faulty. In this case, replace PSN board.
2. If the alarm occurs in line card, check if the same alarm occurs in other line card(s) located in the
same shelf with the faulty line card.
If the same alarm occurs in all other line cards, PSN board might be faulty. Reboot PSN board and
check if the line card alarms are restored. If alarms are not restored, replace PSN board.
If merely the line card where this alarm occurs reboots repeatedly, replace the board where the
alarm is generated.

Alarm Cause
1. The GCS, EC or HPS subcard of UIMC/GUIM/CHUB is not inserted in position.
2. The subcard is faulty.
Impact
UIMC/GUIM/CHUB GCS sub-card functions abnormally. Packets may be lost, and even worse, link
disconnection may occur on the control planes of some boards. For active/standby configuration,
there are two cases:
1. If the active board is abnormal while the standby board is normal, the system performs
active/standby switchover. Thus, the standby board takes over the services of the faulty active
board. In this case, the service is not affected.
2. If both the active and standby boards are abnormal, active/standby switchover is forbidden. In this
case, the service is interrupted because the faulty board cannot restore to the normal status.
Action
1. Check the sub-card connection on the board. If the sub-card is loosely inserted, tightly insert it and
wait for the board to be powered on.
2. Replace the sub-card.

3.1.15 198005665 Fault on board (GPS)
Alarm Information
Code:
198005665
Name:
Fault on board (GPS)
Severity:
Critical
Type:
Equipment alarm
Alarm Description
Clock board or GPS module report hardware error
Alarm Cause
According to alarm details, alarm status falls into two types:
Type A fault on board (GPS) phase-lock equipment (Probable alarm causes include 16chip loss/out
of lock, 12.8M loss/out of lock, PP2S output loss, 8K output loss, 10M output loss, and 1PPS loss).
Phase-lock equipment of this board (GPS) is in power on status (alarm cause is that the GPS module
of ICM board is in power on status, and power on has not been completed).
Impact
Be usually determined as hardware fault, which affects system clock. It might lead to the system
clock loss and system synchronization failure.
When system clock loss/offset occurs, its subsequent impact on service is described below.
1.For TDM transmission, all links based on the TDM transmission medium (including the transmission
link currently in service for UE and cell transmission link) are affected. Packet loss might occur on
these links, leading to degradation of service quality. In the case of serious packet loss, service
interruption and handover failure will occur. Even worse, the cell might be out of service.
2.For non-TDM transmission (for example, IP transmission), Iub interface service is affected, while
Iur interface and Iu interface services are not affected. The clock that Node B derives from RNC
via IEEE1588 is inaccurate.
When RNC clock frequency offset is no more than 0.05 ppm, Node B synchronization will not fail, but
success rate of inter-RNC inter-Node B soft handover might fall.
When RNC clock frequency offset exceeds 0.5 ppm, Node B will fail to lock the clock. In this case,
Node B will oscillate freely and success rate of inter-Node B soft handover might fall.

Alarm Description
Capacity of TRUNK communication is insufficient
Alarm Cause
1. Connection failure.
2. Line failure.
3. Board failure.
4. Rear board failure.
Impact
There is no impact on services when TRUNK connection is not adopted for inter-shelf control plane
communication. However if TRUNK connection is adopted, this alarm indicates insufficient network
communication capability. This may cause congestion at control plane. During heavy traffic period,
this may cause much delay or services interruption in extreme condition.
Action
1. Check whether TRUNK connection is used for inter-shelf control plane. If not, no handling
is required.
2. Check the number of connections, i.e. 4 FEs and 2 GEs are required. Complete the connections if
there is any missing.
3. Check whether the connection is correct.
The correct connection is described as below:
For FE port trunk, if UIM board is installed on BUSN shelf, then TRUNK connection is not supported.
In this case, this alarm won't occur. If UIM is installed on other shelf, FE7, FE8, FE9 and FE10
work together to form a TRUNK port. However if it is GUIM/GUIM2 board, FE3, FE4, FE5 and FE6
form a TRUNK port.
For CHUB board, every 4 adjacent FE ports form a TRUNK port, such as FE1~FE4, FE5~FE8 etc.
For each trunk port, All the 4 RE ports must be connected, and direct connection is recommended.
For GE port trunk, 2 GE interfaces (CHUB board inter-connection) are connected in cross-connection
mode. The #1 GE port on the left board on the local shelf corresponds to the #1 GE port on the left
board on the opposite shelf; the #2 GE port on the left board on the local shelf corresponds to the #2
GE port on the right board of opposite shelf.

SJ-20130408113951-012|2014-04-11 (R1.1)
ZTE Proprietary and Confidential
ZXG10 iBSC Alarm and Notification Handling Reference
Alarm Description
Type B fault on board (GPS) phase-lock equipment
Alarm Cause
Class B faults of GPS module of ICM board are generated by singlechip processor checking,
including antenna feed short circuit or open circuit, poor quality of received satellite signals or difficulty
in receiving satellite signals, and large phase difference of 10M OCXO assistant phase control.
Impact
There is no impact on system clock or services if the type B fault lasts for less than 48 hours. After 48
hours, the system clock is deviated and system synchronization fails. When GPS signal is poor, the
alarm will be repeatedly reported/restored. As long as the alarm lasts for no more than 48 hours, both
system clock and services will not be affected.
When the system clock is lost or clock frequency deviation happens, services may be affected
differently according to transmission mode.
1. For TDM transmission, all links based on TDM transmission medium (including UE transmission
link and cell transmission link) will be affected. Packets may be lost, which leads to degradation
of service quality. In serious situation, services may be interrupted, handover may fail and cell
out-of-service may happen.
2. For non-TDM transmission (e.g. IP transmission), services via Iub interface will be affected. This
fault will not affect services via Iur interface or Iu interface. In this case, Node B will fetch clock signal
from RNC by using IEEE1588 function, but the clock is inaccurate.
When RNC's clock frequency offset is no more than 0.05 ppm, Node B synchronization can be
achieved. But inter-RNC soft handover success rate will fall.
When RNC's clock frequency offset exceeds 0.5 ppm, Node B cannot lock the clock. Then Node B
will work in free oscillation mode. In this case, inter-Node B soft handover success rate will drop.
Action
Check the input circuit of antenna feeder of ICM board so that it can receive good GPS signals.
The checking items include:
1) The position of the receiving antenna.
The antenna should be installed in an open area, far away from high buildings and clear from shades.
The effective visibility angle of the antenna should be greater than 150 degrees.
2) The connection between power splitter and front panel.
The connector used to connect the power splitter and the front panel should be in good contact and
properly connected.

Alarm Cause
Management port or CPU control port has faults.
Impact
Isolate island, checking packets being abnormal or messages between shelves being abnormal may
occur. For active/standby configuration, there are two cases:
1. If the active board is abnormal while the standby board is normal, the system performs
active/standby switchover. Thus, the standby board takes over the services of the faulty active
board. In this case, the service is not affected.
2. If both the active and standby boards are abnormal, active/standby switchover is forbidden. In this
case, the service is interrupted because the faulty board cannot restore to the normal status.
Action
Replace the board. CPU control port, management port or switch chip is error when this alarm
happens. By resetting the board, this fault will be self-cured with very few possibility, and the fault
may remain.

Chapter 3 Alarms
Alarm Cause
1. The network cable connection on relevant equipment (including local/intermediate/opposite
equipment) is loose or disconnected.
2. Intermediate equipment is faulty.
3. Opposite equipment is faulty.
4. Local equipment is faulty.
5. Configuration related to the BFD session is incorrect.
Impact
All services on the path relating to the BFD session will be switched to the standby path. Service
interruption will occur if no standby path exists.
Action
Check alarm details on the NMS Alarm Management interface to find the source address and the
destination address of the BFD session. The source address refers to the address of local equipment.
The destination address refers to the address of the opposite BFD session equipment.
1. Check the status of the line card at the local end. If the line card restarts repeatedly, replace it
and power on.
2. Check the physical connection between the BFD session-related port and the local line card. If the
connection is loose or broken, tighten or replace the cable. If the port indicator is on, it means the
physical connection is normal.
3. Ping intermediate and termination equipment in turn with correct IP address.
i. Telnet to the interface board to check the link by making a ping test. For example, if the destination
address is 2.2.2.10, enter the following command in the telnet interface.
brs_ping_b "2.2.2.10"
ii. Wait for 5 seconds, and then enter the next command.
BrsShowLog "ICMP"
a. If "PING===>destine 2.2.2.10 timeout" displays on the screen, it means the response times out.
b. If "ping_receive:Reply from 2.2.2.10: bytes=60 time<1ms" displays on the screen, it means the link
is normal.
iii. In case of timeout, check if the related route and address are configured correctly. If not, correct
the reconfiguration and do a ping test again.
iv. If the route/address is configured correctly but the repsonse still times out, it means a link is broken
or the intermediate equipment is faulty. In this case, check to see if there is any broken network
cable, loose connection or abnormal equipment along the BFD session path. If yes, take necessary
actions, such as replacing the broken cable, tightening the connection, or repairing or replacing the
fault equipment, to solve the problem.
4. If the ping test indicates that packets can be received and sent normally at both ends, check to see
if the BFD session at both ends is configured correctly by performing the following steps:
i. Check the configuration of BFD session on the NMS Configuration Management interface to
ensure the BFD switch is in "enabled" status.
ii. Make sure that the BFD session is configured with the same working mode at both sides.
iii. Make sure that at least one device plays an "active" role for the BFD session.

iv. Make sure that the BFD session exists at both ends, and that the source and the destination
IP addresses are matched.
v. Make sure that the hop mode (single hop/multi-hop) is consistent at both ends.
vi. Make sure that the authentication information is consistent at both ends.
5. Reboot the board where the interface is located.

Alarm Description
PPP_UID Link Down
Alarm Cause
1. The alarm occurs in PPP port creating, modifying, deleting when PPP port is created by command.
2. The alarm occurs once in PPP port during board power-on, and recovers after successful PPP
negotiation.
3. Physical link is down, or link transmission quality is poor.
4. Adjustment of PPP link parameter leads to link re-negotiation, causing the alarm.
Impact
This will cause disconnection of user plane data and services.
Action
Check alarm details on the NMS Alarm Management interface to find the faulty PPP port ID.
1. Check the cable connections at both ends to see if they are loose or broken. If yes, tighten the
connection or replace the broken cable.
2. Refer to the networking plan to check if the E1 cable is correctly connected.
3. Click IPOverE1 Configuration on the NMS Configuration Management interface to check E1 ID and
time slot. Make sure that the time slot configuration is consistent at both ends.
4. Check PPP parameters on the NMS Configuration Management interface to ensure that the
configuration is consistent at both ends.
5. Check the connection relation of DT and EIPI on the NMS Configuration Management interface to
ensure that the PPP port configuration is consistent at both ends.

ZXG10 iBSC Alarm and Notification Handling Reference
Action
Check alarm details on the NMS Alarm Management interface to find the source address and the
destination address of the BFD session. The source address refers to the address of local equipment.
The destination address refers to the address of the opposite IPD session equipment.
1. Check the status of the line card at the local end. If the line card restarts repeatedly, replace it
and power on.
2. Check the physical connection between the IPD session-related port and the local line card. If the
connection is loose or broken, tighten or replace the cable. If the port indicator is on, it means the
physical connection is normal.
3. Ping intermediate and termination equipment in turn with correct IP address.
i. Telnet to the interface board to check the link by making a ping test. For example, if the destination
address is 2.2.2.10, enter the following command in the telnet interface.
brs_ping_b "2.2.2.10"
ii. Wait for 5 seconds, and then enter the next command.
BrsShowLog "ICMP"
a. If "PING===>destine 2.2.2.10 timeout" displays on the screen, it means the response times out.
b. If "ping_receive:Reply from 2.2.2.10: bytes=60 time<1ms" displays on the screen, it means the link
is normal.
iii. In case of timeout, check if the related route and address are configured correctly. If not, correct
the reconfiguration and do a ping test again.
iv. If the route/address is configured correctly but the response still times out, it means a link is broken
or the intermediate equipment is faulty. In this case, check to see if there is any broken network
cable, loose connection or abnormal equipment along the IPD session path. If yes, take necessary
actions, such as replacing the broken cable, tightening the connection, or repairing or replacing the
fault equipment, to solve the problem.
4. If the ping test indicates that packets can be received and sent normally at both ends, make sure
that the IPD session exists at the local end, and that the source and the destination IP addresses are
matched.
5. Reboot the board where the interface is located.

This alarm is reported if the BSC initiates flow control in "FUC control mode" upon detecting No.7
signaling point congestion on the A-interface.
The "FUC control mode" allows the base station to discard the access messages of some MSs as
required by the BSC.
Alarm Cause
The A-interface is congested with excessive No.7 signaling messages.
Impact
Some users fail to gain access to the system due to the flow control automatically initiated by the
BSC. If the traffic is still excessive after flow control, the signaling on the A-interface may be blocked
and services may be interrupted.
Action
1. Query "Flow Control Level" in the alarm details. If the flow control level is five or lower, wait for
three minutes, and check whether the alarm is cleared.
Yes -> End.
No -> Step 2.
2. Execute the BLK FUTR or BLK CUTR command based on "Site ID", "Bts ID", and "Trx ID" to
block some cells. In this way, the access of some users can be limited to avoid A-interface
disconnection caused by further increase of the No.7 signaling load. Check whether the alarm
is cleared.
Yes -> Step 3.
No -> Step 2.
3. Execute the UNB FUTRX or UNB CUTRX command to unblock some cells one batch at a time
based on "Site ID", "Bts ID", and "Trx ID". The alarm handling is completed.
