Commissioning Wizard processDN999099 © Nokia Corporation Draft 33 (78)Issue 4-0 en Nokia Proprietary and ConfidentialDuring the BTS/BSC start-up scenario the BSC checks the BTS SWand if it is not the correct one, the BSC loads SW to the BTS. Thisloading will take from 5 to 20 minutes, depending on the OMUSIGlink speed. If no SW loading takes place, the process will take about10 seconds.If SW loading takes place, the BCF is in the ‘SW loading’ stateduring the SW loading operation. This information is shown on theBTS Events list. When the SW loading from the BSC is completed,the BCF is reset automatically. This means that the Supervision -Equipment View disappears for a few seconds, but after the BTS hasstarted normally, the commissioning procedure continuesautomatically.After the SW checking and/or loading, the BSC sends theconfiguration data to the BTS and the BCF enters the ‘Configuring’state. It can take up to five minutes for the oven oscillator to warmup after the BTS is powered on. The BTS Events window displays amessage when the oven oscillator is ready.When the BTS is ready for testing, the Wizard automaticallyproceeds to the next wizard page and the BSC runs automatic testson the Abis link and on each TRX installed in the BTS.The Abis loop test will take about two minutes (all channels of allTRXs are tested).2. Abis not connected:If the establishment of the BTS/BSC connection does not succeed(Abis cables are not connected, for example), the BCF remains in the‘Waiting for LAPD’ state. If you now click NEXT, the Wizarddisplays a message (see Figure 8). The message also asks you if youwant to give the ‘Use Current’ command. If you click YES in thedialogue box, the BTS starts to use the BTS SW in the master TRXmemory and the Wizard proceeds to the BTS Test Reporting wizardpage after TRX and BCF achieve the ‘Configuring’ state.

Commissioning42 (78) © Nokia Corporation Draft DN999099Nokia Proprietary and Confidential Issue 4-0 enNoteWith an FXC transmission unit, the cross-connections to this BTS are createdautomatically after the capacity has been set and approved.The capacity to be used is defined by selecting its signal type (TCHs, TRXSIG,OMUSIG, TRXSIG on TCHs or OMUSIG/TRXSIG) and by reserving requiredtime slots and bits. The signal types are explained in more detail in Section 6.2.In the case of 1.5 MB links (T1), the Traffic Manager automatically reduces thenumber of time-slot rows in the table to 24.With EDGE transmission, the dynamic Abis feature is used to improve theefficient the use of transmission resources. This requires allocation of the EGPRSdynamic Abis pool (EDAP) between the available EDGE TRXs in a BTS or BTSchain.6.1 Allocating transmission capacityTransmission allocation capacity and dynamic Abis are both allocated from theTraffic Manager window.6.1.1 Allocating Abis transmission capacityAllocate Abis transmission capacity as follows:1. Select the line interface used (Port 1 - Port 16, depending on thetransmission unit). With an FC E1/T1 transmission card, the only possibleoption is Port 1.2. Click the TCHs button and then click in a cell in the ‘Abis TS Allocationfor this BTS’ table to allocate time-slots. Repeat this step to allocatetransmission capacity to all TRXs in the BTS. See Figure 16 for an exampleof allocating transmission capacity to a TRX.

If EDGE transmission is not required, proceed directly to Section 6.1.4 tocomplete the Abis transmission allocation.For EDGE transmission, proceed to Section 6.1.3 to allocate EDGE TRXsto the dynamic Abis pool.For chained BTS transmission allocation, proceed to Section 6.1.2.6.1.2 Allocating transmission capacity for chainingThe chaining feature is available for BTSs which have been loaded with CX 3.0software or later. Two or three Nokia MetroSite EDGE BTSs can be chainedtogether as one BCF object.For example, a chain of two BTSs might contain five TRXs, as seen in theexample of BTS Manager’s Supervision - Equipment View window in Figure 2.The transmission capacity can be allocated between the TRXs in the chainedBTSs, as described in the procedure below. BTS Manager is connected to themaster BTS in the chain.Before beginning a site expansion, the site must be locked from the BSC or NMSwith BCF lock.You can check if the site has been locked by connecting a BTS Manager laptopto the master BTS in the chain, starting BTS Manager and checking TRXPROPERTIES in the Supervision - Equipment View window (right-click with themouse over a TRX in the window).
Commissioning46 (78) © Nokia Corporation Draft DN999099Nokia Proprietary and Confidential Issue 4-0 enNoteAllocate transmission capacity for chaining as follows:If the FXC type transmission unit replaced an FC type transmission unit during aBTS upgrade for chaining, or if CX 3.0 software (or later) is not loaded at theBTS, the site must be uncommissioned and then re-commissioned beforeallocating transmission capacity for the BTS chain.With BTS Manager, uncommission the master BTS by selectingCOMMISSIONING | WIZARD from the main menu and selecting the ‘UndoCommissioning’ button. Make sure that CX 3.0 or later is loaded at the BSC orNMS and start Commissioning Wizard again, as described earlier in this manual.1. Select the line interface used (Port 1 - Port 16, depending on thetransmission unit). An FXC type transmission unit is required for chaining.2.

Click the right mouse button on the cell to be modified anddelete either one signal allocation, all signal allocations of a particular type ordelete all allocations for the selected port.If you want to modify the allocations after you click OK in the Traffic Manager,you must first run ‘Undo Commissioning’ in the BTS Commissioning Wizard.When the link capacity restricts normal signal allocation, you can use the‘TRXSIG on TCHs’ and combined ‘OMUSIG/ TRXSIG1’ signal types.6.2 Signal typesOMUSIGThe BTS can have one OMUSIG which allocates 2, 4, or 8 bits in one time slotdepending on the link speed used (16, 32, or 64 Kbit/s). If a combinedOMUSIG/TRXSIG1 is used, the allocation of the OMUSIG is disabled.OMUSIG/TRXSIG1The BTS can have one combined OMUSIG/TRXSIG1 which allocates 2, 4, or 8bits in one time-slot depending on the link speed used (16, 32, or 64 Kbit/s). Whena compressed Abis time-slot allocation is used, the OMUSIG/TRXSIG1 can belocated in radio time-slots 1 - 4 (starting from bit 1), which means that it overlapsthe TCHs which are reserved for TRX 1.TCHsThe BTS must be allocated at least as many TCHs as there are TRXs installed init (1 - 4). Each TCH allocates two contiguous time slots (16 bits) for a single TRX,each of which is marked with the TRX number. The TCHs are numbered from 1to 4 in the order they are defined.
