A Standard RS–232 cable can be used with the following modifications: Pin 8 (CTS) does not have to be jumpered/shorted to the others as it is a driver output. The DTR is already a driver output signal. The other pins are to receivers.
BTS Configuration Objective The objective of this procedure is to configure the BTS and establish communication sessions between the LMF and BTS. This procedure consists of: 1. Creating a named hyperterminal connection for MMI communication 2. Establishing an MMI communication session 3. Verify and set IP address 4. Programming customer operating channel 5. Verifying BTS synchronization mode 6. Verifying DPLL tracking 7.

BTS Configuration – continued Updating Default Channel Setting to Customer Operating Channel A non–volatile database containing the default channel and default power level of the site must be programmed. The default channel is the customer operating channel for this site. The default power level must be set to –50 dBm which will be overwritten by the MM/OMCR when the site comes on–line. It is imperative that the customer frequency be programmed into this database.
BTS Configuration – continued Synchronization Background GPS GPS is typically used as the primary timing reference for CDMA BTSs. In applications where RGPS is used, the BTS is said to be synchronous with CDMA system time. The RGPS provides a 1 Pulse Per Second timing reference and Time Of Day information to allow the BTS to synchronize to CDMA system time. HSO A High Stability Oscillator (HSO) within the BTS provides a backup timing reference in the event of a GPS outage.
BTS Configuration – continued sources (RGPS or HSO). Under normal operating conditions, the acquisition states last about 5 minutes. The TK state is the DPLL tracking state and is entered at the end of the acquisition states. The TK state is required for performing ATP. Procedure to Verify and Change BTS Synchronization Mode The Sync button in the Diagnostic Access Area is used to toggle the RGPS or HSO as the primary timing reference for the BTS.
BTS Configuration – continued Procedure to Verify DPLL Tracking (RGPS/HSO) The DPLL within the BTS must be tracking either RGPS or HSO in order to perform ATP. Use the procedure in Table 7-11 to verify DPLL tracking. Table 7-11: Procedure to Verify DPLL Tracking Step Action 1 If an MMI session was established, proceed to step 6.

Test Equipment Calibration Background CAUTION To prevent damage to the test equipment, all Microcell transmit (TX) tests must be made using the 30 dB attenuator. Proper test equipment calibration ensures that the test equipment and associated test cables do not introduce measurement errors, and that measurements are correct. NOTE If the test set being used to interface with the BTS has been calibrated and maintained as a set, this procedure does not need to be performed.
Test Equipment Calibration – continued Procedure to Calibrate Test Equipment The calibrate test equipment function zeros the power measurement level of the test equipment item that is to be used for TX calibration and audit. If both a power meter and an analyzer are connected, only the power meter is zeroed. Use the Calibrate Test Equipment menu item from the Util menu to calibrate test equipment. The test equipment must be selected before calibration can begin.

IMPORTANT * Should there be any issues which affect CLI operations or the UNO/OMCR, this replacement procedure cannot be performed.
Shut Down & Restore BTS Signaling – continued IMPORTANT * The EDIT SECTOR REDIRECT or REDIRECT2 command does NOT affect calls in progress and will NOT move these calls to another sector/carrier. The command only prevents future calls from being originated on the targeted sector/carrier. If active call processing is still taking place in the target sector/carrier, it is advisable to wait for any active calls to terminate prior to disabling the sector.
Shut Down & Restore BTS Signaling – continued Table 8-2: Procedure to Shut Down Signaling Functions Step 3 Action NOTE This step edits the redirect parameters so that the Global Service Redirect Message broadcast on the paging channel redirects all subscribers away from the sector with the failed equipment and onto a different system.
