The software to read the VSWR and DTF is ANRITSU.
Illustration 3.29 : Anritsu Software
Below is the step to configure the VSWR and DTF:
1) Select file, open, and choose the folder.
2) Select the 3G Swap folder and choose the TX1 (VSWR) first and then following
by RX1 (VSWR).
3) Repeat the step for sector 2 and 3.
4) The step for DTF also same with VSWR.

3.4 Project Assignment Switching System
3.4.1 Test DTRU and TRU
Objective of the project is to do the installation and testing on the TRU and DTRU
units. trainees are exposed in testing DTRU and TRU first. During the practical, in
the five weeks, trainees are inducted into repairing centre to help staff to make the
testing. After week 12, a trainee should make preparation for the MLTN
documentation. Refer to the appendix D. The steps taken are same for both of TRU
and DTRU except the coding are different for each of them.
1. Identify the type of RBS cabinet

RBS 2202
RBS 2206
Illustration 3.37 : RBS cabinet
2. TRU (transceiver unit) is installed on RBS 2202 while DTRU (double
transceiver unit) is installed on RBS 2206.
Illustration 3.38 : Types of cabinet
51
3. Let the installation of TRU begins.The TRU unit has to be installed properly
to avoid any disfunctional. Switch on the power supply and it takes three to
four minutes for the TRU to be ready.
52
Illustration 3.39 : The installation of TRU/DTRU
4. On the front panel there are five indicators and three push buttons for
RESET, LOCAL/REMOTE and TEST CALL.
53
Illustration 3.40 : TRU front panel
Table 3.4 : TRU indicator
5. After waiting for 3 to 4 minutes, the TRU are ready to be tested. The unit is
connected to CPU. Insert the program coding from the CPU to test whether
the TRU is operational or faulty. Coding is provided by the Ericsson's
company to let the system to be functional.(refer to appendix A)
54
Illustration 3.41 : Coding interface in winfiol software
6. If the coding has successfully been programmed on the TRU without any
problem, the indicator light on the front panel will appeared green. Therefore,
it is clearly stated that the TRU is fully operational. Besides that, TRU can be
corrupted if the program is buffering and detect any faulty when coding is
been inserted. Therefore, the indicator light will appeared red. Then, the test
result form has to be filled.(refer to Appendix B)

7. Lastly, deliver the TRUs that have been inspected and packing to the
Ericsson’s company.
3.5 Project Assignment Mini link – traffic node team
3.5.1 Introduction
The trainee had been attached to the unit so called Mini Link – Traffic Node or
MLTN after week 12. This unit had been formed under the Transmission Division to
carry out the transmission project awarded by Ericsson Malaysia Bhd. for the client
Digi Telecommunication Sdn. Bhd. MLTN (Mini Link TN) itself is the name of the
product produced by Ericsson AB Sweden for transmission, which Bird Technology
Sdn. Bhd. (Bird Tech) carry out the survey, installation, testing and commissioning
for Mini Link equipment. Furthermore, Bird Tech is among the telco service
provider in Malaysia registered with Ericsson to carry out the installation of the
Ericsson’s equipment either for Node B project or transmission project. Bird Tech
also renowned as the expertise in switching led by the company’s Managing
Director, Tuan Haji Pauzi B. Yusoh. Besides that, Bird Tech also has a lab which
57
equipped with Ericsson’s Mini Link TN test bed for training purposes and equipment
testing.
In the MLTN Unit, the trainee had been appointed by the company as a trainer under
MLTN project coordinator to support and complete the MLTN documentation(refer
appendix C) after Planning, Installing & Testing and Commisioning were done or
running.

3.5.2.2 Project Implementation
In the project implementation, there were divided by six stage which is installation,
testing,pre acceptance,cutover ,dismantling and final acceptance.
After all the process has been done, trainer must do the documentation of this
project. The MLTN document include site survey and site design document.

As a conclusion, trainer have complete three Site Document for MLTN including
the amended after the supervisor has checked it.
The documentation written by using Microsoft excel and Autocad 2009 for drawing
sheet and must be convert into PDF file after all the document sheet approve by the
supervisor.
