Introduction The DA Commissioning Unit (DACU) is used during system commissioning and routine maintenance. The Unit can be used to commission the AS4000DA Central Terminal. 2. DACU Components Component DACU RF Coupler 50 Ohm Termination RF Connecting Lead Power Connecting Lead RS232 Modem Shelf Interface Cable RJ11 to 9 way Connection Adapter PC Interface Cable 9way-25way PC Interface Cable 9way-9way 3. Architecture Overview The Commissioning Unit architecture as depicted in Figure 1. Components comprise: i. Commissioning Unit 4. ii. Cables and couplers to allow the Commissioning Unit to be connected to the RF sub-system. iii. Cables to allow the Commissioning Unit to be connected to each Modem Shelf (to support communications to each Shelf Controller). iv. Associated system firmware upgrades required to support AGC operation in cards such as the Shelf Controller. Principles of Operation The Commissioning Unit acquires a full low rate RF downlink / uplink through RF cabling coupled into the CT transmit / receive antenna ports. Knowledge of the path loss between the Commissioning Unit and RF antenna port allows the Commissioning Engineer to adjust RF receive level as required using AS8100 Sitespan. The Commissioning Unit scans and acquires a CDMA link to allow a specific RF channel to be quickly adjusted during commissioning (or re-checked by a visiting maintenance engineer) Page 11 of 28 © Copyright Airspan 2000 AS4000 DA CT Commissioning Unit Operators Manual GSI 002 605-0000-455 Issue 2.0.

Preparation for Commissioning at the Central Terminal To make it possible for the test DACU to acquire a link the RW Management and Net Entry has to be set via the AS8100 Sitespan as follows: 1. From the Object List Shelf view select the modem shelf, click right mouse button and select the ‘element view’ 2. Select the DTU on the modem shelf and click right mouse button, select Airspan DTU properties 3. In the Edit card state window set max net entry channels to 1, set the number of Free list entries at 160K 80K and 40K to 0. Page 17 of 28 © Copyright Airspan 2000 AS4000 DA CT Commissioning Unit Operators Manual DLP 001 605-0000-455 Issue 2.0 Date 21/03/00 4. In order to acquire a test radio link using an ST, Sitespan must be used to place RW codes ‘Out of Service’(OOS) for either 10k or 160k bandwidths. These can be selected from the DTU card properties. The options for each RW code are: • IS • OOS • OOS(10k) bandwidth. • OOS(160k) bandwidth. - The RW is in service - This takes the RW out of service. - This puts the RW in Test Mode, allocating a 10kbit/s - This puts the RW in Test Mode, allocating a 160kbit/s The DTU card view shows all of the RW codes, and their current state within the system (i.e. OOS or IS). IMPORTANT NOTE: An RW code can only be placed Out of Service if it is currently not in use by the system. Before proceeding, it is important that the DTU card view is checked, 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 click left mouse button until OOS is selected. Repeat for RW2 and RW3 to prepare for commissioning. Once RW codes have been reserved for Test links, the ST can be programmed in the usual method, although the RW channels that the 10kbit/s and 160kbit/s links are acquired on, must be the same as the ones set-up in the DTU card properties (i.e. NOT RW 15!). Page 18 of 28 AS4000 DA CT Commissioning Unit Operators Manual DLP 001 605-0000-455 Issue 2.0 Date 21/03/00 2. Power Cycle the Rack The rack should be power cycled. 3. Check DACU Calibration Each DACU is provided with a calibration table on the cover unit a typical table is shown below. The path loss is equal to the sum of the unit losses and external losses. Cable Loss dB Coupler Loss 80 80 80 80 80 Unit loss 17 17 17 17 17 RX sensitivity -98 -99 -100 -101 -102 Power meter Reading -3.68 -2.68 -1.68 -0.68 +0.32 Table 1. DACU Calibration Table 4. Set Rx Sensitivity 1. Type:Acc> TE 0 Acc> WU C 1 4000d 0 0 0 (where 4000d indicates version 4.13) Acc> WU F A 2. Program the DACU via the LAT port to the correct frequency, PN code and ID number. 3. Set RW. WU I 1 1 1 1 WU W WU I0 1 Where is in HEX, 17 dec = 11 hex, and pn is 1 in most cases. 4. Write data into ST: - WU W 5. 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 the management system. The DACU becomes registered when its ESN is entered into the management system database. A registered ST can acquire the uplink and maintain periodic information exchange with the shelf’s SC. The ‘LK’command forces the DACU to acquire a link as follows: LK RW Code Page 19 of 28 PN Code Up Link Rate * Down Link Rate* Overlay Frequency channel number code within channel plan AS4000 DA CT Commissioning Unit Operators Manual DLP 001 605-0000-455 Issue 2.0 Date 21/03/00 * The rate at which the link will acquire is defined as follows: 1: 10kbit/s 40kbit/s 80kbit/s 4: 160kbit/s 7. For testing type in the code relating to the system as set up i.e. LK 7 1 4 4 0 9. In the example above the DACU is forced to acquire on RW 7, PN 1, with Uplink and Downlink 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 1 1 1 0 1 to set channel 2. 8. Type W 426 to monitor link state. 9. The DACU will return with: Display D: 0426 0000 D: 0426 0101 D: 0426 0303 D: 0426 0B0B D: 0426 0808 D: 0426 0909 *Note: relate to a link failure Interpretation No Link Downlink Acquired Uplink Acquired (transitory state) Uplink Acquired * Downlink has failed * Uplink has failed Table 2 Link States 10. Once the DACU acquires the link, the RX gain can be commissioned. If the link does not acquire, then it will be necessary to change the RX gain through Sitespan. To check if the Link has acquired check the Green LED is illuminated on the Modem Card. The top 4 LEDs show the first modem at the different acquisition rates and the next 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, set the RX gain to around 2200. ( if value is reduced power goes UP). Check the output power of the DACU, and repeat until the output power matches that in the DACU Calibration Table. 14. Record the result. The values of the TX and RX gain must be set into the Sitespan at the AC before the backhaul is connected to the CT, failure to do this results in the TX power and RX sensitvity values being overwritten by the value stored in the Sitespan Server. Page 20 of 28 AS4000 DA CT Commissioning Unit Operators Manual DLP 001 605-0000-455 Issue 2.0 Date 21/03/00 15. When the Sitespan connects it configures the OOS and Net Entries but as a precaution it 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 now fully commissioned. 5. Restoring shelf connections 1. Remove the test equipment and connecting cables. 2. Replace the Shelf covers and the protective cap on the coupler.
