2. Site Awareness

There are a number of site in Canada that are in remote location that require

situational awareness therefore when travelling to and from remote site locations it is important that the engineer is equipped for travel to remote sites

Engineers must also be aware that Tower work takes precedent over any other site work; therefore if tower work is in progress then the tower crew is in control of the site.

(3)

2009-05-15 HUAWEI Confidential Page3, Total30 If required the engineer may have to remain off site until tower crews have finished any ongoing operations. If tower work is in progress then hard hats are required to be worn onsite.

3. Commissioning Process

The commissioning process for the Huawei DBS3900 will follow the flow shown below. The following section will provide a breakdown of the activities required for successful commissioning of the base station.

(4)

2009-05-15 HUAWEI Confidential Page4, Total30

4. NTP Report

The NTP report is a report that details which sites have received “Notice to Proceed” (NTP) from the customer. This report then provides the basis for scheduling activities for commissioning preparation and commissioning activities. From this report a forecasting schedule will then be produced to initiate the site configuration data to be prepared and the scheduling of engineers to attend site for commissioning.

The details of this process are not covered in this document and is only included for informational purposes.

5. Commissioning Preparation

In order for commissioning preparation to be considered complete the following must have happened.

1. Confirmed NTP report released, hardware installation completed, NodeB was powered on and IP connectivity is available (Telus)

2. Iub data and cell data for the NodeB is downloaded to RNC (Huawei) 3. Cells were correctly declared on Core Network side (NSN)

4. NodeB was created on OSS (Huawei)

5. IPCLK links were created on 2 IPCLK servers

6. Sub-contractor team got the correct NodeB software and Script from Huawei. 7. Sub-contractor team got the special USB memory stick with LED available and

kept the NodeB software and script with the correct name, file format in the correct path as following:

NodeB software: \\NodeB\Software\Software.cspBoot BootROM: \\NodeB\Software\Firmware.csp

Data configuration file: \\NodeB\Configuration\NodeBCfg.xml

Make sure that each USB stick is only kept with 3 files above dedicatedly for one NodeB, it’s better to label the USB stick with the site Name before commissioning to avoid the USB sticks mixing if more than 1 site will be integrated for one team.

(5)

2009-05-15 HUAWEI Confidential Page5, Total30

6. Site Keys and Codes

In order for the engineer to be able to attend a site for commissioning it will be necessary for the keys and/or codes to be signed out. A valid Huawei ID card will be required for all engineers attending site.

Sign out Telus Mobility key from Huawei Region PM. Approved footwear must be worn

• All employees must have a hard hat, hard hat must be worn at all times when a tower crew is on site

7. Site Access Procedures

On attending site the engineer will be required to follow the site access procedures laid out below.

• Upon entry into the site one person must immediately call the security control center and report what site you have entered, provide your name and you are from Huawei, report site name and site number, report what your work order is to be on site.

• The security control center phone number, site name and site ID is posted on the wall beside the phone

• If there is a site book you must log into the book.

• When you are last person in the site you must call security control and sign out from the site before leaving.

• You must take care and ensure that the lights are turned off, the shelter door is locked and properly closed, shut the gate and close the gate lock.

This procedure must happen all the time, every time.

8. Site Installation Checks

Before the engineer begins the commissioning of the base station they will be

required to carry out an audit of the installation quality. There are two parts to the audit, the first is checklist for the BBU hardware, and the second is the checklist for the

(6)

2009-05-15 HUAWEI Confidential Page6, Total30 DCDU. Please refer to the document: <Telus Checklist for Hardware

Installation.>

Both checklist need to be completed, photographs must be taken and submitted as part of the site documentation.

<Site ID>_<Equipment>_Photo.jpg (Overview, DCDU, BBU and Power)

Once the audit checks have been completed and no major issues have been found then commissioning can commence. If any major issues are found then the issue must be recorded and escalated to Huawei Regional PM and Huawei RNC Engineer

9. BBU Serial Number

After BBU hardware checking, find the BBU serial number as following and record the number with the file:

<Site ID>_BBU SN_<Serial Number>.txt For example 21023156401000001572

10. Local Commissioning

There are 2 possible ways to commission the Huawei DBS3900, the first is the USB commissioning method and the second is the LMT Commissioning method, both are covered below.

10.1 USB Commissioning

Please refer to the document: < DBS3900 Commissioning Key Point Guide_Telus>

DBS3900 automatically reads the related software and data configuration file under the fixed directory structure from the USB stick and verifies their names and formats:

NodeBsoftware: \\NodeB\Software\Software.csp BootROM: \\NodeB\Software\Firmware.csp

Data configuration file: \\NodeB\Configuration\NodeBCfg.xml Downloading the Software and Data Configuration File

1. Connect the USB Memory stick provided by Huawei to the USB port on the BBU3900 (do not use the test port). If the USB Memory stick is detected correctly the following should happen within 20 seconds: the LED on the USB disk is blinking; the RUN LED on the WMPT is blinking quickly (On for 1s, OFF for 1s) about 2 seconds, ALM LED on WMPT is “ON” since the hardware is different with the default scripts; CPRI LED on WBBPb are “OFF”.

2. Once the downloading of the software and configuration to the DBS3900 begins the following should be occurring: the LED on the USB disk is blinking, the RUN LED on the WMPT blinks quickly at 4 Hz(0.125s ON, 0.125s OFF) configuration file, it will last about 15 minutes.

3. The software is automatically activated on the DBS3900 when this happens the RUN LED on WMPT blinks at 4Hz (ON for 0.125s, OFF for 0.125s) the

RUN LED Blinking (ON

ALM LED “ON” WMPT

(8)

2009-05-15 HUAWEI Confidential Page8, Total30 USB LED remains solidly “ON”. It will take about 10 minutes to activate the software.

4. The DBS3900 will carry out a reset after the software and the data

configuration has been activated. During this process the LED on the USB will transition from ON->OFF->Blinking; the RUN LED on WMPT transitions: ON->OFF->Blinking (ON for 0.125s, OFF for 0.125s); RUN LED on the 2 WBBPb will blink respectively; CPRI LED on WBBPb will flash once “RED” and then become “Green”. The full reset will take about 5 minutes.

5. After the reset is complete, DBS3900 runs normally, the status should now be: LED on USB is “OFF”; RUN LED on WMPT blinks (ON for 1s, OFF for 1s); ALM LED on WMPT stays “OFF” (If there are no alarms); RUN LED on WBBPb blinks (ON for 1s, OFF for 1s);CPRI LED on WBBPb stays “GREEN”

(20)

2009-05-15 HUAWEI Confidential Page20, Total30

12. Cell Orientation

Prior to call testing it is necessary for the local engineer to verify that there are no crossed fibers/feeders present in the configuration. To do this the engineer will need to us a compass to find orientate the direction of the sectors and then verify the Cell ID and scrambling codes for each antenna. The diagram below details the orientation of the Antennas, the first sector (Alpha) is the one orientating to the north east, alone the clockwise, are the second (Beta) and the third (Gamma) sector.

Once the cell orientation has been verified then call testing can begin. ( Telus has some special sites, which are not defined like this, Huawei will provide a list of these kind of sites)

13. Call P Testing

13.1 Call-P Procedure

Call P testing is to be carried out with co-ordination with the RNC Engineer; there are 3 sections to the Call P process, which are:

• Dedicated Call Tests • Basic Service Tests • Handover Tests

Please call RNC Engineer to check all cells are available. And then ask them to block 800 Cells, you can make all the 1900 Calls and Handover

Alpha Gamma

(21)

2009-05-15 HUAWEI Confidential Page21, Total30 After you finish the 1900 call test, please call RNC Engineer to unblock 800 cells and block 1900 cells, you can make 800 calls and Handover

After you finish the callp, please call RNC Engineer to unblock all cells and tell them the Callp on site finished.

Record the all of the test results to <Site ID>_Telus_CallP Record after finished each test.

PS: When you make the PS handover test, please remember to record the average download speed to ‘Telus_CallP Record’ spreadsheet.

13.2 Dedicated Call Test (For you reference)

This section of call testing consists of a number of standard calls that test the routing of calls between the site and fixed line numbers in both directions (only one of each call is required per Site). Call tests should consist of the following:

• Mobile to Fix line using 11 digits (Local Site telephone can be used for this purpose)

• Mobile to Fix line using 10 digits (Local Site telephone can be used for this purpose)

• Fix line to Mobile using 11 digits (Local Site telephone can be used for this purpose)

• Fix line to Mobile using 10 digits (Local Site telephone can be used for this purpose)

13.3 Basic Service Tests and handover test (For you reference)

This section of call tests deals with testing the services on each cell of the Site, one of each of the following tests is required in order to achieve a pass grade for the cells (unless know conditions exist to prevent one or more of the tests, details of these conditions must be detailed in the Call P documentation).

1. Call RNC Engineer to block all 850 cells. Then make Voice call and video call in each 1900 cell. Make sure the PSC is right in each cell.

2. Make a call and walk around the site, to make sure there is no call drop. And then reverse to make sure there is no call drop

15 Handover Testing Guide

Handover tests are to be carried out under the direction of the RNC engineer as the RNC engineer will need to monitor and feedback the current serving cells information to the onsite engineer. Testing will differ slightly between S111 and S222 sites due to the different in cells present on the site. The general concept of the handover testing

(27)

2009-05-15 HUAWEI Confidential Page27, Total30 is to achieve intra-frequency (and in the case S222 sites inter-frequency) handovers between adjacent cells on the site.

• Intra-Frequency Handover S111:

1. [RNC engineer] Unblock the 3 cells of each sector.

2. [Site Engineer] Make sure mobile phone camp on the cell of sector Alpha, originate a voice call to the 2nd mobile phone.
