RF Interconnect The Commissioning Unit has two RF ports (SMA connectors 50 Ohm impedance) the RF lead is connected to port A and to the RF antenna port using one length of RF cable and one coupler per antenna port. Unused ports are terminated using 50 ohm RF loads. All couplers and cables are marked to show insertion loss. Antenna Feed J2 80 dB Coupler N type connector J1 J3 SMA connector DIP/LNA 5.3.

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.
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.

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.

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 2 40kbit/s 3 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.

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.
