Check whether there is good electrical connection between the UPS shell and the
UPS external box via screws. UPS external box should be grounded.
Check whether the protection grounding cable of AC lightning protection box or
IAFB is directly connected to the protection grounding bar. Make sure the
grounding cable is shorter than 1m.
The AC power cable from the exterior to the BTS should be directly connected to
the AC lightning protection box (when AC lightning protection box is available) or
to the IAFB (when AC lightning protection box is unavailable). It is not allowed to
connect the external power cable to the power distribution terminal in the work box
first and then to the AC lightning protection box.
When E1 cable is used for signal transmission of the BTS, if the E1 cable from the
exterior to the BTS is coaxial cable with metal shell (provided by the user), its
metal shell should be grounded with grounding clip. The grounding cable from the
grounding clip should be directly connected to the protection grounding bar
instead of to the grounding bar of the IAFB.
In BTS outdoor tower installation mode, the shielding covering of the BTS coaxial
feeder should be grounded at the tower-top and the front end connecting the BTS.
The grounding cable should be connected to the tower body nearby. The
protection grounding bar should have separate grounding donwlead that is not
insulated from the tower body.
When the feeder is not shorter than 60m, the shielding covering of the coaxial
feeder should be grounded at the middle of the tower body.
II. Checking indoor grounding
Indoor grounding check includes the following aspects:
In BTS indoor installation, there should be indoor grounding bar and outdoor
grounding bar that should be led into the counterpoise separately instead of being
connected in series directly with grounding cables.
The grounding cable at the point where the feeder enters the feeder window is
connected to the outdoor grounding bar in the direction from the antenna to the
BTS.
The AC lightning protection box provides separate grounding cable to connect to
the indoor grounding bar. The grounding cable from the AC lightning protection
box or from the IAFB to the indoor grounding bar should be shorter than 1m.
Check whether there is good electrical connection between the UPS shell and the
UPS external box via screws. UPS external box should be grounded.
When E1 cable is used for signal transmission of the BTS, if the E1 cable from the
exterior to the BTS is coaxial cable with metal shell (provided by the user), its
metal shell should be grounded with grounding clip. The grounding cable from the
grounding clip should be directly connected to the indoor grounding bar instead of
to the grounding bar of the IAFB.

B Requirements for Antenna Isolation
B Requirements for Antenna Isolation
I. Requirements for isolation of omni antenna
Based on the conditions that antenna gain is 10dBi and isolation is 30dB, the spacing
between antennae is required as follows:
When antennae are installed horizontally, the horizontal spacing between transmit
(TX) antenna and receive (RX) antenna should not be less than 5.3m.
When antennae are installed vertically, the vertical spacing between TX antenna
and RX antenna should not be less than 0.2m.
According to the requirements for diversity receiving of omni RX antenna, the
horizontal spacing between RX antennae should not be less than 4m.
II. Requirements for isolation of directional antenna
1)
Single polarization antenna
Based on the conditions that antenna gain is 15dBi, isolation is 30dB and half-power
angle is 65°, the spacing between antennae is required as follows:
When antennae are installed horizontally, the horizontal spacing between TX
antenna and RX antenna in the same sector should not be less than 3m.
When antennae are installed vertically, the vertical spacing between TX antenna
and RX antenna in the same sector should not be less than 0.2m.
The horizontal spacing between TX antenna and RX antenna in different sectors
should not be less than 0.2m.
According to the requirements for diversity receiving of directional RX antenna, the
horizontal spacing between RX antennae should not be less than 4m
2)
Dual polarization antenna
For dual polarization antennae, the spacing between the ports of the RX and TX
antennae is 30dB. Therefore, the horizontal spacing may not be considered during
horizontal installation. But in vertical installation, the vertical spacing between antennae
of different sectors should not be less than 0.2m.
& Note:
The antenna isolation requirements in this section are subject to typical applications. They are for

D Preparing Grounding Clips
D Preparing Grounding Clips
D.1 Overview
During the entire installation, there are many places where grounding clips should be
applied. The following is the summary of the places where grounding clips are required.
1)
Normally, each feeder should be grounded at the following three points at least for
lightning-protection:
Within 1m's reach behind the place where the feeder is led from the tower
platform;
Within 1m's reach in front of the place where the feeder is led from the tower body
to the outdoor cabling rack;
At the outer side of the feeder window before which the feeder is led into (on the
spot).
When the length of the feeder along the tower body exceeds 60m, more
lightning-protection grounding clips should be added in the middle of the tower body.
Typically, one clip is installed for every 20m.
2)
If the feeder is led into the room after being routed for a stretch of distance on the
building-top, and the distance exceeds 20m, a lightning-protection grounding clip
is required on the top of the building.
3)
For the feeder that enters the room from the building-top along the wall, if an
outdoor cabling rack is used, the cabling rack should also be grounded.
D.2 Preparation Process
1)
Prepare the required tools, such as paper cutter, flat screwdriver and nipper pliers,
etc.
2)
Unpack the box and bags containing the lightning-protection grounding clips and
put various parts and accessories on clean ground or paper for use, as shown in
Figure D-1.

4.2 Installing GPS Antenna
4.2.1 Requirements for Installation Position
The installation position of GPS antenna should have a broad vision without high
buildings around, and as far as possible from the compact accessory buildings on the
building-top. The available area of the plane for installing GPS antenna should be as
big as possible. And the antenna should be vertically erected with a visual angle
greater than 90°. See Figure 4-1.

Figure 4-1 Antenna installation position
Note that the antenna should not be close-range radiated by the front of the main
lobe of the mobile communication antenna. In addition, it should not be located at
the range of the microwave signal from microwave antenna, not below the high
voltage cable, nor under the intense radiation of TV launching tower.
Considering lightning protection, try the best to install the antenna at the center of
the building-top. Do not install it on the stub wall around the building-top. DO not
install it at the corner of the building-top as the corner has the greatest possibility
of being stricken by lightning.
The antenna should be installed at the place where there is special lightning
arrester or similar facilities such as telecommunication tower around. And the
antenna should be located within the valid protection range of the lightning
arrester. That is, the included angle between the erect direction and the direction
from the antenna RX connector to the lightning arrester or to the tower-top should
be less than 30°. If there is no tower or lightning arrester around, the special
lightning arrester should be installed to meet the design requirements for lightning
protection of the building. The horizontal distance from the lightning arrester to the
antenna should be 2m to 3m preferably. And the lightning arrester should be 0.5m
higher than that of GPS antenna receive connector.

Caution:
1) Waterproof treatment should be performed at the antenna connector. Please refer to Section 2.3.6 for
waterproof treatment process.
2) Upon completion of installation, cover the antenna support with anti-rust paint, especially the fastening
bolts, expansion bolts and the places around the bolt holes.
4.3 Installing GPS Feeder
GPS feeder installation includes the installation of jumpers, antenna-side lightning
arrester, feeder, equipment-side lightning arrester, etc. The intallation and routing of
GPS feeder is similar to that of RF feeder. Following gives explanation of points for
attention and grounding requirements during the installation.
4.3.1 Routing Feeder
Prior to feeder routing, carefully check the routing environment including the tower and
building-top. Determine the routing scheme and sequence as per the engineering
drawing.
In the case of BTS indoor installation, the route leading the feeder from the
installation position to the equipment room containing the cabinet and equipment
should be clear. It should facilitate fixing the cable properly and meet the routing
requirements in the equipment room. In addition, reliable measures should be
taken to protect the feeder from rain and corrosion.
1.5m jumper should be bound at the outside of the antenna support lever evenly
with cable ties. In addition all cable ties should be fastened, with the same spacing
of 200mm. The cable tie heads should be toward the same direction, and all the
ties should be cut neatly to the end.
Waterproof elbow should be made at the entrance where the feeder enters the
equipment room. The vertical distance from the lowest point of the waterproof
elbow to the entrance should not be less than 200mm so as to prevent rain from
entering the room.
In the case of GPS antenna installed on building-top, connectors at both ends of
the feeder should be protected with strong materials (such as packing bags for
board) to prevent damage to the connectors. The feeder should be fixed with
plastic clips attached with steel nails along the root of the parapet on the
4-8
Installation Manual
iSiteC BTS3601C CDMA Base Station
Hardware Installation
4 Installing Satellite Synchronization Antenna and Feeder System
building-top. The spacing between plastic clips should be 1m. And the direction of
the clip heads should be interlaced regularly. If two feeders are joined, they should
be bound together without intersection or curve.
When routing the feeder, try to expand the feeder roll before routing. Try to avoid
bending of it. If it is unavoidable to bend the feeder, the bent radius should not be
less than the minimum of the allowed bent radius for the cables so as to avoid
damage to the feeder.
Caution:
When the distance from the antenna to the BTS is greater than 100m, 7/8 feeder should be adopted so as
to minimize signal loss. If it is unavailable, 1/2 feeder should be adopted, instead.
4.3.2 Installing Lightning Arrester
There are two types of lightning arresters for GPS antenna, i.e. antenna-side lightning
arrester and equipment-side lightning arrester. The former is used for lightning
protection for active GPS antennae, while the latter for the GPS card. The two arresters
are of the same model.
Currently there are two types of lightning arresters. The installation procedure for each
type is described in detail as follows:
I. Type iS-MR50LNZ+6 lightning arrester
Figure 4-9 illustrates the appearance of Type iS-MR50LNZ+6 lightning arresters.

Installation Manual
iSiteC BTS3601C CDMA Base Station
Hardware Installation
4 Installing Satellite Synchronization Antenna and Feeder System
Attention:
1)
GPS antenna-side lightning arrester
The "PROTECTED" end of the GPS lightning arrester should face the antenna.
That is, the "PROTECTED" end of the arrester is connected with the jumper end.
The lightning arrester should not be grounded when it is installed either on the
tower or on building-top, but the feeder grounding clip should be as close as
possible to the lightning arrester.
The lightning arrester is installed inside the lightning arrester box, with its
connectors sealed with waterproof adhesive tape and PVC tape in sequence, so
as to prevent moisture invasion.
2)
GPS equipment-side lightning arrester
The "PROTECTED" end of GPS lightning arrester should face the BTS. That is,
the "PROTECTED" end of the arrester is connected with the GPS port of the BTS.
In the case of BTS indoor installation, dual-male conversion connector should be
used to connect the lightning arrester directly to the GPS port of MBPM. It is
unnecessary to connect the lightning arrester to lightning protection grounding
cable.
In the case of BTS outdoor installation, dual-male-connector jumper of 0.3m long
should be used to connect the lightning arrester to the GPS port of MBPM. The
arrester should then be connected to the lightning protection grounding cable that
leads to the grounding bar of the BTS. The connector between the arrester and the
feeder should be sealed with waterproof adhesive tape and PVC tape in sequence,
so as to prevent moisture invasion.
II. Type DGXZ+6NFNM-A lightning arrester

Hardware Installation
4 Installing Satellite Synchronization Antenna and Feeder System
1)
GPS antenna-side lightning arrester
The connectors on both ends of Type DGXZ+6NFNM-A lightning arrester are
male and female respectively. Therefore, jumpers with male and female
connectors should be prepared for the installation of the lightning arrester. The
male connector of the jumper is connected with the GPS antenna, while the
female connector on the other end is connected with the male connector of the
lightning arrester.
The lightning arrester should not be grounded when it is installed either on the
tower or on building-top, but the feeder grounding clip should be as close as
possible to the lightning arrester.
The lightning arrester is installed inside the lightning arrester box, with its
connectors sealed with waterproof adhesive tape and PVC tape in sequence, so
as to prevent moisture invasion.
2)
GPS equipment-side lightning arrester
In the case of BTS indoor installation, the lightning arrester may be directly
connected to the GPS port of MBPM. And it is unnecessary to connect the
lightning arrester to the lightning protection grounding cable.
In the case of BTS outdoor installation, a 0.3m jumper with both male and female
connectors should be used. Its male connector is connected to the GPS port of
MBPM of the BTS, while its female connector to the male connector of the
lightning arrester. The lightning arrester should be connected to the lightning
protection grounding cable that leads to the grounding body of the BTS. And the
connector between the lightning arrester and the feeder should be sealed with
waterproof adhesive tape and PVC tape in sequence, so as to prevent moisture
invasion.
4.3.3 Grounding Requirement
GPS feeder grounding and routing are conducted simultaneously. The following gives
description of feeder grounding points in different installations.
I. BTS outdoor installation (building-top installation excluded)
Within the range of 1m~2m under the GPS antenna;
The front end connecting the BTS.

feeder, with the clip spacing of 20m.
2) If the GPS feeder is led into the room after being routed for a stretch of distance on the building-top, and
the distance exceeds 20m, a feeder grounding clip is required on the top of the building.
3) For the GPS feeder that enters the room from the building-top along the wall, if a cabling rack is used,
the cabling rack should also be grounded.
IV. BTS indoor installation with GPS antenna not on the BTS tower but
separately placed
The shielding covering of GPS feeder is grounded at the entrance to the building.
The grounding point should be the outdoor grounding bar of the mobile equipment
room. The grounding cable should adopt the plastic insulation copper core wire of
diameter not less than 6mm2. It should be black, or yellow and green.
If the feeder is longer than 60m, feeder grounding clips should be applied in the
middle of the feeder, with the clip spacing of 20m.

1 Overview of Software Installation
1.1 Overview of Software Installation
BTS3601C software includes BTS operational software and terminal Operation &
Maintenance (O&M) software.
BTS operational software includes BOOT software, Central Processing Unit (CPU)
software, and Field Programmable Gate Array (FPGA) logic.
CPU software includes Micro-bts Base-band Processing Board (MBPB) software and
Micro-bts Transceiver Board (MTRB) software; while FPGA logic includes MBPB logic
and MTRB logic. The actual situation differs from one board type to another.
Terminal O&M software includes Local Maintenance Function (LMF) software (i.e.,
the local O&M software), and O&M Center (OMC) software (i.e., the remote O&M
software).
LMF software comprises PC self-contained Telnet and File Transfer Protocol (FTP)
software, while OMC software is composed of BAM software and Client software.
1.1.1 BTS Operational Software
I. BOOT software
BOOT software serves to start the board. Before the delivery of the BTS3601C, the
BOOTROM in every board has already been installed with BOOT software. BOOT
software upgrade is usually realized by replacing the chip.
II. CPU software
CPU software is the core of system functions. It can be loaded in two ways:
If there is no old-version software on the board, it is necessary to load the board
(in the commissioning mode) with the software through the board network port.
If there is old-version software on the board, the software can be upgraded
through software loading by using local FTP software or remote O&M software.
III. FPGA logic
FPGA logic should be loaded to BTS3601C MBPB/MTRB. The loading mode is the
same as that of CPU software.

Installation Manual
iSiteC BTS3601C CDMA Base Station
Note:
The BTS operational software has been installed before delivery, so there is no need to install onsite.
However, the operational software needs to be upgraded or re-loaded upon version upgrade. For details,
please refer to Chapter 3 BTS Operation Software Installation.
1.1.2 Terminal O&M Software
I. Local O&M software
The local maintenance console is a portable computer installed with Windows9x
Operating System (OS), which contains the local O&M software. It includes FTP
Client (Ftp.exe) and Telnet Client (Telnet.exe).
The BTS3601C objects, including sites, cells, basebands, carriers, channels, etc.,
can be maintained with local maintenance commands.
Since the two programs (Ftp.exe and Telnet.exe) are provided by Windows9x OS,
there is no need for extra installation.
II. Remote O&M software
Remote O&M software (OMC) of the Base Station Subsystem (BSS) adopts the
Client/Server structure.
Through the Client, users can input operation commands, which are then processed
by the server (BAM) in a centralized way. After the processing, these commands are
transmitted to the foreground (including BSC and BTS), which will then return the
operation result (success, failure, timeout, exception, etc.). BAM will record the result
and transmit it in a certain report format to the Client.
With OMC, the user can perform remote maintenance and monitoring over all the
BTSs that are under his control.
The collected site information can also be used for network planning.
The installation of OMC software involves the installation of BAM server software and
the installation of the Client software.
The Client software is divided into three kinds: BSC Client, BTS3612 Client and
BTS3601C Client.
This manual describes the installation of BTS3601C Client software only. For the
installation of BAM server and other Client software, please refer to the
corresponding installation manual.

3 Installing BTS Operational Software
3.1 Software Media
BTS3601C software has two kinds of media:
Memory chip
Disk file
For specific software, their respective media are described as follows:
I. For BOOT software
Boot software includes the fundamental hardware initialization information of boards.
Before delivery, BOOTROMs of all boards are pre-installed with BOOT software,
which can be upgraded by replacing chips.
II. For CPU software
CPU software is the core of system functions. Before delivery, CPU software has
been loaded to the Flash Memory. Once the equipment is powered-on, BOOT
software will load the CPU software from Flash Memory to RAM and run it there.
When CPU software should be reloaded or upgraded during the maintenance
process, CPU software in disk file format can be loaded to the corresponding Flash
Memory through the remote or local maintenance console.
III. For FPGA logic
FPGA logic is responsible for board data exchange. It is loaded in the same way as
the CPU software.
3.2 Replacing the Chip
Generally, the BOOT software is updated by replacing the chip. All you need to do is
to replace the program chip of the old version software with the chip of the new
version.

Note:
1) The four angles of the chip correspond to those of the socket one by one. Make sure there is no
mistake when replacing the chip. Otherwise, the chip may be burned.
2) The chips should be replaced by authorized Huawei engineers.
3.3 Downloading Software
The boot software of BTS3601C system is installed and upgraded by replacing the
memory chip, while common board software (including CPU software and FPGA logic)
are installed and updated by downloading the software.
3.3.1 Methods of Software Loading
BTS software loading can be conducted through remote/local maintenance console.
The remote maintenance console is connected to BSC via LAN. Through IP Over
ATM (IPOA) link of BSC, it is connected to MBPM of BTS3601C, and through MBPM,
it is connected to Micro-bts Transceiver Module (MTRM).
The local maintenance console is connected to MBPM (via the Ethernet port in
MBPM maintenance window) through the crossover network cable. Through MBPM, it
is then connected to MTRM.
The connection between BTS remote maintenance console and local maintenance
console is shown in Figure 3-1.

It is quite convenient to load the board software to BTS3601C through remote/local
maintenance console.
The processes of software installation and version upgrade for BTS3601C through
the local and remote maintenance consoles are almost the same.
In the following text, the remote maintenance console is used as an example to
describe the process.
3.3.2 Remote Loading
I. Overview
The system provides the remote loading function to enable the maintenance
personnel to load software to the BTS3601C boards through the remote maintenance
console.
Software loading includes downloading of software and uploading of BTS
configuration data. While the software downloading still comprises two steps:
1)
Downloading BTS3601C software;
2)
Activating BTS3601C software.
If the loaded software is MBPB software and when it is activated, the BTS3601C will
be reset and MBPB will start the newly-loaded software.
If the loaded software is the MTRB software and when it is activated, MBPB will load
the corresponding MTRB software stored in the memory just now to the specific
board.
In receipt of the new software, the board will activate the software by resetting itself.
The software loading is then completed.
II. Precautions
1)
Software loading should be carried out based on the actual conditions.
According to the version matching table, FPGA software should be loaded first,
then the CPU software.
2)
Since the solidified software is generally loaded by off-line replacing the chip,
there is no requirement on the sequence.
3)
The board software loading should follow the sequence of "MTRB first, MBPB
later". While loading software to a specific board, the sequence of "FPGA first,
CPU later" should be followed.
4)
The software version fallback of boards follows the sequence MTRB→MBPB,
the fallback sequence of software on a board is CPU first, then FPGA, so the
general sequence is like this:
MBPB.FPGA.

2 Installing BTS Terminal O&M Software
2.1 Software Features
BTS3601C terminal O&M software (hereinafter referred to as "terminal O&M
software") is classified into two categories: the remote O&M and the local O&M.
These two categories differ in the way they are installed.
I. Local O&M software
Local O&M software includes FTP Client (Ftp.exe) and Telnet Client (Telnet.exe). The
two programs are both self-contained by Windows9x OS.
To realize the local maintenance, the maintenance console is connected through
crossover network cables to BTS via the Ethernet port that is in the Micro-bts
Base-band Processing Module (MBPM) maintenance window. The user thus can
issue O&M commands through the local maintenance console to maintain the
BTS3601C.
II. Remote O&M software
The remote O&M software comprises the software for the BAM server and the Client.
Among which, the Client software is composed of three parts: BSC Client, BTS3612
Client and BTS3601C Client. The remote O&M software described in this manual
refers to BTS3601C Client.

4 System Commissioning
4.1 Modes of System Commissioning
4.1.1 Local Commissioning
Local commissioning is performed through BTS3601C local maintenance console.
The user can log in to the BTS3601C in the Telnet mode, and commission the
BTS3601C objects with Man-Machine-Language (MML) commands.
Please refer to the module of "Maintenance Console" in User Manual for details of
commissioning commands.
4.1.2 Remote Commissioning
In the remote commissioning mode, the user can input the commissioning command
at the OMC Client. After receiving the command, BAM server will process it and send
it to the BTS3601C. When the response returns from the BTS3601C, BAM server will
record the operation result (success, failure, timeout, abnormality, etc.) and send the
returned operation result in a certain report format to the Client.
For specific operations, please refer to cBSC Operation Manual.
4.2 Power-on Operation of Software
After the BTS3601C is powered on, the software of various boards will conduct
self-test and necessary initialization.
After the system operation becomes stable, MBPB will acquire the basic configuration
parameters to set up the Operation & Maintenance Link (OML) for the BTS3601C
(The protocol involved is BOOTP, a standard protocol in TCP/IP protocol family, which
can be used to obtain IP automatically).
MBPB will also judge whether there are correct configuration data in the BTS3601C
Flash Memory. If there are correct configuration data, MBPB will directly send the
data to each board for configuration. If there is no correct data, MBPB will request the
data from OMC, and send it to the BTS3601C boards for configuration.
The following section briefs the startup and operation of BTS3601C.
4-1
Software Installation & System Commissioning
0错 误 表 格 结 果 无 效
Installation Manual
iSiteC BTS3601C CDMA Base Station
4.2.1 Board Startup and Indicator Description
When the BTS3601C is powered-on, BOOT software of each board will start running
to transfer CPU software from Flash Memory to Random-Access Memory (RAM), and
start the self-test and initialization.
If the initialization is successful, the board will send a request to Operation &
Maintenance Unit (OMU) for configuration; otherwise, board will be reset and
restarted.
There are three indicators on both the board panels in the maintenance window of
MBPM and MTRM respectively. From top to bottom they are: RUN (operation
indicator, green), ALM (alarm indicator, red) and ACT (work indicator, green).
The following briefs the statuses of indicators. For details, please refer to chapter
"Introduction to Module Maintenance Window" in the User Manual.
When MBPB/MTRB has no configuration data, all the three indicators will fast
flash at the frequency of 4Hz.
When MBPB/MTRB is downloading the software, indicator RUN will fast flash at
the frequency of 4Hz.
When the board is in normal operation, indicator RUN flashes slowly at the
frequency of 0.5Hz, while "ACT" keeps on, and "ALM" is off.
When alarms occur in the operation of the board, indicator ALM will flash at
different frequencies to indicate different alarm levels.
4.2.2 Setting up OML
After the self-test, MBPB will set up OML with OMC first.
OML is set up through the following procedures:
1)
MBPB in the BTS3601C sends BOOTP request to OMC;
2)
After receiving BOOTP request from the BTS3601C, OMC will fill the
corresponding BOOTP response frame (including the IP address, subnet mask,
gateway address, etc. of this BTS3601C) according to BOOTP information of the
relevant BTS3601C configured before. OMC will then send the frame to the
BTS3601C.
3)
According to the received BOOTP response frame, BTS3601C will set its own IP
address and the related routing data;
4)
After obtaining IP address and creating the route, the BTS3601C will send to
OMC a request to setup TCP link. In receipt of the request, OMC will set up the
OML to that BTS3601C.

4.2.3 Setting up Abis Signaling Link
After the configuration of the BTS3601C, MBPB will set up Abis signaling link
according to the configured parameters and exchange signaling with the BSC.
4.2.4 Setting up Cells
When Abis signaling link is set up, MB PB will report the configuration status of
BTS3601C resources to BSC and ask for logical configuration.
After BSC sends cell configuration data to MBPB, BTS3601C will configure the
relevant carrier attributes, set up common channel and update the overall messages.
So far the cell has been set up and MSs can access the network and originate calls.
4.2.5 Normal Operational Status
Once the BTS3601C comes into normal operation, MSs can access the network and
make calls.
However, sometimes it is found that although MTRM is in normal operation without
any critical alarms, MSs cannot access the network and make calls. To solve such
problem, the user can take the following measures:
Check whether MTRM has power output.
Check whether the system messages are issued normally.
Trace and locate the fault by using a signaling analyzer or the Abis interface
tracing function of the maintenance console.
During the operation, if the board ALM indicator flashes, it indicates that alarms have
been generated. In this case, the user can query at the BTS3601C terminal
maintenance console for specific alarm description and take the corresponding
measures.
4.2.6 Clock Reference Source
The cdma2000 1X is a synchronization system. A precise reference clock should be
provided for the BTS3601C.
The BTS3601C can receive the clock signal from multiple clock reference sources,
including: GPS clock reference source, GLONASS clock reference source and
external clock reference source.

4.3 Commissioning Board Software
4.3.1 Testing Links
The normal operation of communication links is the precondition for the board
software to operate normally. By querying alarms, the user can check whether the
OMLs between BTS3601C boards and OMU are normal, and whether the signaling
links between the boards and the main control Signaling Processing Unit (SPU) are
normal.
Besides, users can use the BTS3601C local/remote maintenance console to issue
commands to perform loopback test on the boards. In this way, the user can ensure
the normal operation of the communication links.
4.3.2 Processing Faults and Alarms
I. Description of alarms
The faults occurred on the modules during BTS3601C operation will be reported to
OMU in logs or alarms. After recording and processing, OMU will report them to
OMC.
The alarms generated by BTS3601C include the following levels: critical, major, minor
and notice.
What follows is the introduction to various module alarms items:

4.4 Call Function Test
After the hardware installation, check, software installation and basic commissioning,
the user should start the BTS3601C overall function test: service function test.
4.4.1 Test Equipment
I. Abis interface signaling monitoring
Connect the signaling protocol tester (such as K1205 and MA10) to the E1 cables
between BSC and BTS. Set the protocol stack as Abis interface, and select the
timeslot to be monitored according to BSC configuration.
If no signaling tester is available, the OMC interface tracing function also works.
II. Call generator
It is used to simulate multi-user call setup.
III. Test MS
It is used to test the service functions.
4.4.2 Preparations for Service Function Test
Before the test, make the following preparations:
1)
Make sure that BSC and BTS3601C are properly connected. BSC and
BTS3601C can be connected via E1/T1 or optical fiber. Make sure that the
connection is correct before the system is powered on.

2)
Make sure the O&M and signaling links on Abis interface are connected properly.
The connection status of the OMLs and signaling links on Abis interface can be
queried through the OMC BAM.
3)
Make sure cell configuration is correct, and the MS can access the network at
the configured frequency.
4.4.3 Service Flow Overview
When switched on, an MS may be either in the idle mode or the dedicated mode. In
the idle mode, the MS will monitor the radio surroundings and find a suitable service
cell to stay; then the MS will monitor the paging channel in the service cell so as to
receive the paging messages from the network side. In the dedicated mode, the MS
exchanges signaling and data with the network.
The basic flow is as follows:
1)
Location update flow
2)
Mobile Originated Call (MOC) flow
3)
Mobile Terminated Call (MTC) flow
4)
Handoff flow
5)
Mobile originated SMS flow
6)
Mobile terminated SMS flow
7)
Mobile originated call packet data flow
8)
MS packet data flow (downlink service rate)
Flows 1), 2), 3), and 4) are of basic radio connection; while flows 5), 6), 7), and 8) can
be independent flows, or be additional part of flows 1), 2), 3), and 4).
I. Location update flow
The MS notifies the network of its current location in the network through the location
update flow so that the network can provide service.
In the following situations, MSs will originate the location update:
When an MS moves into a new location area
When it is time to perform periodic location registration. The time for periodic
location update is designated in the system message received from the network.
II. Mobile originated/terminated call setup flow
These are two basic connection flows of CDMA system. The call may be a speech
call, or a data call.
In an mobile originated call, the called party may be a CDMA mobile subscriber, a
PSTN subscriber, an ISDN subscriber, a CSPDN subscriber or a PSPDN subscriber.
4-10
Software Installation & System Commissioning

Installation Manual
iSiteC BTS3601C CDMA Base Station
In the mobile terminated calls, the calling party may be a cdma2000 1X mobile
subscriber, a PSTN subscriber, an ISDN subscriber, a CSPDN subscriber or a
PSPDN subscriber.
III. Handoff flow
In cdma2000 1X system, handoff has three types: soft handoff, softer handoff and
hard handoff.
Soft handoff or softer handoff can ensure MSs the uninterrupted service when they
are crossing the cell or sector border; while in the hard handoff, the existing
connection has to be cut off before the new connection can be set up.
If the subscriber's current channel suffers from serious interference, the service on it
can be handed over to another channel to prevent the interruption. The QoS is thus
improved. The handoff flow is an important means for the operators to deal with
temporary service overload of cells.
The handoff flow is not independent. It is a part of other basic service flows.
IV. Mobile originated/terminated Short Message Service (SMS) flow
cdma2000 1X supports the point-to-point SMS flow, so that subscribers can send and
receive SMs. It is different from the cell broadcast SMS, which is the
point-to-multipoint broadcast service.
Mobile originated SMS flow is to send an short message from the MS to the Message
Center (MC); on the contrary, mobile terminated SMS flow is to send an short
message from the MC to the MS.
V. MS packet data flow
cdma2000 1X supports packet data service flow. It provides the high-speed data
service transmission capability of up to 156.3kbit/s.
The MS can be used either as a terminal to run data services such as surfing the
internet and sending/receiving E-mails, or as a data channel for other terminals (such
as computer and PDA) to run data services.

II. Test steps
1)
Make sure the network data setting is correct.
2)
Switch on the test MS
3)
Observe the signaling on Abis interface.
III. Expected test result
By tracing the signaling on Abis interface, the possible results of the location update
include:
1)
The network side accepts the MS location update request;
2)
The network side rejects the MS location update request.
4.4.5 Test of MOC Flow
I. Test condition
This test should be conducted after a successful location update flow, when the MS
should display the current PLMN No. or operator name.
II. Test steps
Call a PSTN subscriber with the MS.
III. Expected test result
In normal cases, the called PSTN subscriber establishes a bidirectional conversation
with the MS after ringing and off-hook.
4.4.6 Test of MTC Flow
I. Test condition
This test must be preceded by a successful location update flow. The called MS
should reside in the coverage of the tested BTS3601C, and display the current PLMN
No. or operator name of the network.
II. Test steps
Call the test MS from a PSTN telephone set.
III. Expected test result
In normal cases, the test MS establishes a conversation with the calling PSTN
subscriber after ringing and off-hook.

4.4.7 Test of Handoff Flow
I. Test condition
1)
This test should be performed after the above three tests and in the area
covered by at least two cells. One of cell should be configured with several
sectors, so that the test of the softer handoff can be conducted.
2)
The sectors (or omni cells) that compose the overlapped radio coverage should
be configured with different frequencies, so that the hard handoff can be
conducted.
3)
The related handoff data should have been configured;
4)
Dedicated test MSs;
5)
Change the IMSI of the MS, and redefine the subscriber. In this way, the MS can
access the network by selecting a certain basic frequency or auxiliary frequency
in the sector (or omni cell) that is configured with multiple frequencies.
II. Test steps
1)
Use an MS to call a PSTN subscriber and establish a conversation.
2)
Move the MS from the source sector to the adjacent sector within the same cell
to test the softer handoff performance.
Only when the adjacent sector is also configured with the frequency at which the
MS has established the conversation in the source sector, and the frequency is
available, can the softer handoff be achieved.
3)
Move the MS from the source cell to the target cell to test the soft/hard handoff
performance.
When the MS establishes a connection at a frequency in the source cell, while the
target cell is not configured with this frequency, the hard handoff will occur. If the
target cell is configured with this frequency and this frequency is available, the soft
handoff will occur.
III. Expected test result
1)
Soft handoff and softer handoff
Normally, when the MS moves to the adjacent cell/sector, the target pilot channel will
be shown in the active set of the MS pilot set.
During the conversation, the mobile subscriber feels no interruption or call drop, and
the voice quality is good.
2)
Hard handoff
Normally, when the MS moves to the adjacent cell or sector, it is visible in the active
set of the MS pilot set that the source pilot channel is deleted, and the target pilot
channel is added.

The mobile subscriber will feel temporary conversation interruptions.
Note:
If the actual test conditions cannot meet the standard, the test flow can be simplified like this: Make an
MOC/MTC, and move the MS repeatedly between the adjacent cells, or between the adjacent sectors in
one cell. Whether the handoff flow is normal or not can be judged by observing whether or not there are
conversation interruptions, and by the voice quality.
4.4.8 Test of Mobile Originated SMS Flow
I. Test condition
1)
The test should be performed after the location update flow test;
2)
The system must be configured with Message Center (MC);
II. Test steps
Use an idle MS to send an short message through the specified MC.
III. Expected test result
In normal cases, the MS that originates the short message will prompt that the short
message has been transmitted successfully. The corresponding short message can
be queried at the MC.
4.4.9 Test of Mobile Terminated SMS Flow
I. Test condition
Location update flow test is completed.
II. Test steps
Input an short message to MC properly. The receiver of the short message is the test
MS that is in the idle status.
III. Expected test result
In normal cases, the called MS will ring to indicate that the MS has received the short
message and is ready to display the content of the SM.

the ESCAM message and performs the Supplemental Channel (SCH) setup or
SCH extension.
4.4.11 Test of MS Packet Data Flow (Downlink Service Rate)
I. Test condition
1)
The system adopts dynamic rate allocation;
2)
A cdma2000 1X MS, a set of BlueRose and a ready FTP server;
II. Test steps
After the MS logs in to the FTP server under the control of the BlueRose, originate
the FTP file downloading, and test the downlink rate of a single subscriber under the
following conditions respectively:
--The adjacent cell and target sector are not loaded. The MS is stationary, and is
within short distance to the BTS3601C.
--The adjacent cell and target sector are not loaded. The MS is stationary, and is
within long distance to the BTS3601C.
--The adjacent cell and target sector are not loaded, and the MS is moving (15, 30,
70km/h), and is within short distance to the BTS3601C.
--The adjacent cell and target sector are not loaded, and the MS is moving (15, 30,

--The adjacent cell is 100% loaded. The target sector is 50% loaded. The MS is
moving (15, 30, 70Km/h), and is within long distance to the BTS3601C.
III. Expected test result
In normal cases, the downlink data service rate keeps stable.
Note:
There are multiple test conditions listed in the test steps. It does not mean that all of them are necessary
during the actual test.
4.4.12 Processing of Abnormalities in the Test
In normal cases, the above flows can pass the test. When abnormalities occur in the
test, they cannot be all attributed to the fault of BTS3601C.
The service flow test does not only test BTS3601C, but also the whole CDMA 1X
system. The parts tested include BTS3612, BTS3601C and BSC6600 of BSS.
Besides, also tested are MSC/VLR, HLR, and AUC of the NSS and their interfaces to
PSTN and Internet. The fault of any part of the system may result in the failure of the
flow. Therefore, the analysis should be made based on the actual conditions when a
fault occurs.
BTS3601C is responsible only for the radio transmission. If the MS can access the
network and set up the radio service link, then we say the BTS3601C is in normal
operation.
Take the location update flow as the example. If a location update request is rejected,
basically it is due to the abnormality of the network equipment, or to be more specific,
the problem with the data setting of HLR. Based on the rejection reason in the
message for the rejected location update, further cause for the rejection can be
figured out.
