installed or run on the network. Do NOT run any hacker software on the network.
Do not set network services of any kind on the network such as BBS, NEWS, WWW, and FTP,
without authorization.
Do not connect the computer running the NMS to the Internet for other unrelated operations unless
absolutely necessary, as this may increase the traffic of the network card and affect the transmission
of normal NM data.
Improperly modifying the network settings, IE browser settings and machine name of the system
may cause the NMS to work abnormally. Any setup or modification of the network structure,
network service, firewall, and router, and IP address must be first approved by the related personnel.
The servers and operation terminals should be set with power-on and screensaver passwords that
meet the security requirements and should be changed at regular intervals.
Do not do anything unrelated to maintenance on the network equipment, for example, chatting
on-line, playing games, and listening to music.
Do not use any floppy disk that is not scanned for virus first or that comes from an unknown source.
Do not allow any computer without security mechanism to be connected to the network. If
absolutely necessary, it should be provided with security protection means and be authorized by the
related personnel in advance.
Do not set any “full control” sharing directory on the network. If absolutely necessary, the following
conditions should be met:
1) The full control should be for the specified users only. Everyone full control should be avoided.
2) The sharing setting should be cancelled immediately after the use.
3) The directory that needs to be shared for a long time should be set with the read-only right.
4) Any logical driver mapping to the shared directory should be cancelled.
Make available the virus-killing software and scan the computers and floppy disks that need to be
connected to the network, and scan the servers and operation clients at periodical intervals.
Back up the data at periodical intervals during daily running for possible restoration when faults
occur, for example, due to virus infection.

alarms and history alarms. There is a great volume of history data, so you need to specify the period to limit
the volume of data returned when you query history alarms. The list allows you to sort, filter, and group the
results of the query. You can also export the results as Excel or Web files, and print them.
This function is used for query, simple analysis, and maintenance of the system data.

4 Common Problems
4.1 Common Problems in Remote Sensing
1. During remote sensing, the status bar shows “Incorrect repeater No.”.
Reason: The repeater No of the site in the database does not matches that on the device side. You can
modify the repeater No in the system to match that of the device in the “Site Management”. When
the actual number of the site is unknown, you can consult the original data provided by various
manufacturers for check or directly inquire the related manufacturers.
2. During remote sensing, the status bar shows “5: Repeater No, 0: Device No; The device is not
found!”.
Reason: The device No of the site in the database does not matches that in the repeater. You can
modify the device No to match that of the device in the “Site Management”.
3. During remote sensing, the status bar shows “Other errors”.
Reason: This is the response of the repeater to the NMS command. The reason should be that an
operation command is not supported by the repeat of this type or the device type is not added in the
system.
4.2 Common Problems in Remote Control
The setting fails during the remote control of a site.
You are recommended to first perform remote sensing before you perform remote control. Perform remote
control only after remote sensing normally returns results. If remote sensing is successful but remote
control fails, the reasons may be:
1) The monitored version of the repeater does not match that at the NMS, so the remote control
instruction from the NM center is not correctly parsed.
2) The monitoring unit of the repeater fails, for example, damaged storage chip, so that the parameters
that are to be modified by the NMS remote control instruction cannot be stored.
3) The monitoring units of some devices are not designed to support the modification of the parameter.

5 Description of Common Alarm Parameters
Below please find the alarms of the common GrenTech repeater models. The alarm parameters of other
manufacturers are currently unknown since they are not described in the protocols provided. However, you
can understand them according to the following descriptions. For how to handle the alarms, you can also
directly inquire the appropriate manufactures.
5.1 Common Alarms
Power failure alarm: When the repeaters have abnormal power supply due to a power outage or
other reasons, the monitoring module will send the “power failure alarm” to the NMS by using the
backup battery. For GreTech power modules, the normal input voltage range is 180~260V, and the
normal output voltage range is 7~11V. Alarms will occur beyond this range.
Power module status alarm: This is reserved for the solar energy battery, and currently our devices
do not support this interface.
Self-excitation alarm: The device experiences self-excitation and fails to work normally. This will
affect the device and the wireless network and may even interfere with the BTS in the worst case.
When self-excitation occurs, the GrenTech devices will automatically shut down the power amplifier
and report an alarm. When the NMS receives the alarm, and the self-excitation temporarily clears
since the power amplifier is turned off. Self-excitation that occurs after it is put into service may be
due to the following reasons: 1) The location of the antenna is deviated and this reduces the isolation,
which needs on-site check; 2) The host BTS or the surrounding radio environment changes, in which
case the device parameters need to be adjusted accordingly; 3) The gain and attenuation of the
device are not set properly, in which case you can query the history records in the NMS and modify
accordingly.
Door control alarm: The chassis of the device is opened; the door of the chassis is not closed
properly after site upgrade or debug, or the door is closed properly but the door control switch is
damaged. All these could cause such alarm.
Failure of the uplink low-noise amplifier: The device fails to work normally, the uplink signals are
affected, and the calls may be not available in the coverage area. On-site handling is required.
Failure of the downlink low-noise amplifier: The device fails to work normally, the downlink
signals are affected, and the calls may be not available in the coverage area. On-site handling is
required.

Overpower of the uplink power amplifier: The output power of the uplink power amplifier is
above the set threshold and this may cause interference to the BTS. You can increase the attenuation
of the uplink power amplifier to adjust the uplink output power by remote control on the NMS.
Overpower of the downlink power amplifier: The output power of the downlink power amplifier
is above the set threshold and this may affect the coverage area of the repeater. You can increase the
attenuation of the downlink power amplifier to adjust the downlink output power by remote control
on the NMS.
Over-temperature of the uplink power amplifier: The temperature of the uplink power amplifier
is too high (the threshold for GrenTech device is 70 ºC), and this may cause the power amplifier
module to work abnormally.
Over-temperature of the downlink power amplifier: The temperature of the downlink power
amplifier is too high (the threshold for GrenTech device is 70 ºC), and this may cause the power
amplifier module to work abnormally.
SWR alarm of the uplink power amplifier: The RF signals of the uplink power amplifier of the
repeater are not effectively outputted via the antenna, and calls cannot be connected normally in the
coverage area. The possible reason is that the antenna feeder connector is in loose contact or flooded.
SWR alarm of the downlink power amplifier: The RF signals of the downlink power amplifier of
the repeater are not effectively outputted via the antenna, and the signals are weak in the coverage
area.
Rx/Tx signal alarm: This is mainly for the front/back-end communication of the divided devices,
for example, abnormal communication of the monitoring signals between the input end of the fiber
repeater and the coverage end, abnormal communication of the monitoring signals between the
indoor coverage unit and the trunk amplifier. Such alarms cause the failure of the back-end devices
to be monitored on the NMS. Possible causes: 1) The front-back-end monitoring data cable fails or
the connector gets loose or the optical path attenuation is so large that causes high BER; 2) The front
and back-end programs do not have the same version or the DIP switches are not set correctly on one end.
