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 s cheduling 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 a ttend site for commissioning. The details of this process a re 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 s tick with the site Name before commissioning to avoid the USB sticks mixing if more than 1 site will be integrated for one team.

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 da ta 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 p ort). 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 f or 1s, OFF for 1s) about 2 seconds, ALM LED on WMPT is ON! since the hardware is different with the default scripts; CP RI 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 2009-05-15


Page7, Tota l30


Security Level:

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 W MPT 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!

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 li st 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 E ngineer; 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 a vailable. And then ask them to block 800 Cells, you can make all the 1900 Calls and Handover
