IntroductionThe DA Commissioning Unit (DACU) is used during system commissioningand routine maintenance. The Unit can be used to commission the AS4000DACentral Terminal.2. DACU ComponentsComponentDACURF Coupler50 Ohm TerminationRF Connecting LeadPower Connecting LeadRS232 Modem Shelf Interface CableRJ11 to 9 way Connection AdapterPC Interface Cable 9way-25wayPC Interface Cable 9way-9way3. Architecture OverviewThe Commissioning Unit architecture as depicted in Figure 1. Componentscomprise:i. Commissioning Unitii. Cables and couplers to allow the Commissioning Unit to be connected tothe RF sub-system.iii. Cables to allow the Commissioning Unit to be connected to each ModemShelf (to support communications to each Shelf Controller).iv. Associated system firmware upgrades required to support AGC operationin cards such as the Shelf Controller.4. Principles of OperationThe Commissioning Unit acquires a full low rate RF downlink / uplink throughRF cabling coupled into the CT transmit / receive antenna ports. Knowledge ofthe path loss between the Commissioning Unit and RF antenna port allows theCommissioning Engineer to adjust RF receive level as required using AS8100Sitespan.The Commissioning Unit scans and acquires a CDMA link to allow a specificRF channel to be quickly adjusted during commissioning (or re-checked by avisiting maintenance engineer)

Preparation for Commissioning at the Central TerminalTo make it possible for the test DACU to acquire a link the RW Management and Net Entryhas to be set via the AS8100 Sitespan as follows:1. From the Object List Shelf view select the modem shelf, click right mouse button andselect the ‘element view’2. Select the DTU on the modem shelf and click right mouse button, select Airspan DTUproperties3. In the Edit card state window set max net entry channels to 1, set the number of Freelist entries at 160K 80K and 40K to 0.
AS4000 DA CT Commissioning UnitOperators Manual DLP 001605-0000-455Issue 2.0 Date 21/03/00Page 18 of 284. In order to acquire a test radio link using an ST, Sitespan must be used to place RWcodes ‘Out of Service’ (OOS) for either 10k or 160k bandwidths. These can be selectedfrom the DTU card properties. The options for each RW code are:• IS - The RW is in service• OOS - This takes the RW out of service.• OOS(10k) - This puts the RW in Test Mode, allocating a 10kbit/sbandwidth.• OOS(160k) - This puts the RW in Test Mode, allocating a 160kbit/sbandwidth.The DTU card view shows all of the RW codes, and their current state within thesystem (i.e. OOS or IS). IMPORTANT NOTE: An RW code can only be placed Out of Service if it is currentlynot in use by the system. Before proceeding, it is important that the DTU card view ischecked, to ensure that the RW code is in the desired state.5. In the RW management window place the mouse pointer over the IS for RW 1 clickleft mouse button until OOS is selected. Repeat for RW2 and RW3 to prepare forcommissioning. Once RW codes have been reserved for Test links, the ST can beprogrammed in the usual method, although the RW channels that the 10kbit/s and160kbit/s links are acquired on, must be the same as the ones set-up in the DTU cardproperties (i.e. NOT RW 15!).

Check DACU Calibration Each DACU is provided with a calibration table on the cover unit a typical table isshown below. The path loss is equal to the sum of the unit losses and external losses.CableLoss dB CouplerLoss Unit loss RXsensitivity Power meterReading1 80 17 -98 -3.682 80 17 -99 -2.683 80 17 -100 -1.684 80 17 -101 -0.685 80 17 -102 +0.32Table 1.

Program the DACU via the LAT port to the correct frequency, PN code and IDnumber.3. Set RW.WU I 1 1 1 1WU WWU I <stid> <pn> 0 1Where <Stid> is in HEX, 17 dec = 11 hex, and pn is 1 in most cases.4. Write data into ST:- WU W5. Once the DACU has booted-up, put it into test mode by typing: TE 0.6. Note: A configured DACU cannot maintain its uplink without being registered by themanagement system. The DACU becomes registered when its ESN is entered into themanagement system database. A registered ST can acquire the uplink and maintainperiodic information exchange with the shelf’s SC.The ‘LK’ command forces the DACU to acquire a link as follows:RWCode PNCode Up LinkRate * Down LinkRate* Overlaycode Frequency channel numberwithin channel planLK 8 1 4 4 0 9
AS4000 DA CT Commissioning UnitOperators Manual DLP 001605-0000-455Issue 2.0 Date 21/03/00Page 20 of 28* The rate at which the link will acquire is defined as follows:1: 10kbit/s240kbit/s380kbit/s4: 160kbit/s7. For testing type in the code relating to the system as set up i.e. LK 7 1 4 4 0 9. In theexample above the DACU is forced to acquire on RW 7, PN 1, with Uplink andDownlink of 160kbit/s, using RF channel 9 within the RF band.With the LAT connected to the DACU, ensure that it has booted-up.Type: LK F 1 1 1 0 1 to set channel 15 and LK 1 1 1 1 0 1 to set channel 1 or LK 2 11 1 0 1 to set channel 2.8. Type W 426 to monitor link state.9. The DACU will return with:Display InterpretationD: 0426 0000 No LinkD: 0426 0101 Downlink AcquiredD: 0426 0303 Uplink Acquired (transitory state)D: 0426 0B0B Uplink AcquiredD: 0426 0808 * Downlink has failedD: 0426 0909 * Uplink has failed*Note: relate to a link failureTable 2 Link States10. Once the DACU acquires the link, the RX gain can be commissioned. If the link doesnot acquire, then it will be necessary to change the RX gain through Sitespan. Tocheck if the Link has acquired check the Green LED is illuminated on the ModemCard. The top 4 LEDs show the first modem at the different acquisition rates and thenext 4 LEDs show modem 2.11. Using Sitespan highlight the shelf, and edit ‘parent properties’.12. Select ‘Airspan DA CT modem shelf’.13. Adjust the ‘Rx Gain’ by increasing and decreasing the values. Note: To start with, setthe RX gain to around 2200. ( if value is reduced power goes UP). Check the outputpower of the DACU, and repeat until the output power matches that in the DACUCalibration Table.14. Record the result. The values of the TX and RX gain must be set into the Sitespan atthe AC before the backhaul is connected to the CT, failure to do this results in the TXpower and RX sensitvity values being overwritten by the value stored in the SitespanServer.

When the Sitespan connects it configures the OOS and Net Entries but as a precautionit may be prudent to set all lists in the DTU properties to OOS.16. Power off the DACU.17. With the LAT connected to the DTU, restore the DTU from test mode by typing TE 1.18. Disconnect the RF cables from the rack and connect the Antenna. The rack is nowfully commissioned.5. Restoring shelf connections1. Remove the test equipment and connecting cables.2. Replace the Shelf covers and the protective cap on the coupler.
