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.

Huawei DBS3900 Commissioning Procedure
Security Level:
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.

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.

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”

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
