1 Overview
1.1 Presentation This scenario is applicable if: There is no change in the BTS configuration (e.g. no TRE, sector, GPRS addition/removal during the operation) When the type of TRE is changed, the TRE frequency band remains unchanged When the ANX is changed to ANC, ANB, AGX, AGY, AGC and AGC9P, the sector frequency band remains unchanged The ANB boards can only be used for reduced configurations.
1.1.1 Cases The following cases apply: C1: Replace TRE modules: C1.1: Replace one or several TREs with Evolution TREs (EDGE compatible) C1.2: Replace one TRE/TRA with a TWIN TRA (1 TRX, Non-TX-Div, 2 RX-Div) C1.3: Replace two TRE/TRA with a TWIN TRA (2 TRX, Non-TX-Div, 2 RX-Div). C2: Replace an old SUM board with a new SUM board, where old SUM board can be SUMP or SUMA and new SUM board can be SUMA or SUMX. C3: Replace one or several ANx (ANX, ANC, ANB) modules with ANC, ANB, AGX, AGY, AGC or AGC9P modules, without SUM board move C4: Replace one or several ANx (ANX, ANC, ANB) modules with ANC, ANB or AGX, AGY, AGC or AGC9P modules, with SUM board move.
Note:
Several cases can be combined at the same time. For the reduced configurations, the ANX modules can be replaced by the ANB boards.
1.1.2 Options None.

1 Overview
1.1.3 Restrictions The following restrictions apply to 9100 BTS: For 9100 BTS Mini 3x1 TRE (indoor and outdoor), ANX cannot be replaced with ANC (even if all ANX are replaced with ANC) With the old subrack version (STASR 3BK 07193 AAxx), ANX must not be replaced with ANC or with ANB (no holes for ANC or ANB screws).

1 Overview
1.2 Preparation 1.2.1 Prerequisites The following prerequisites apply: For cases C1.2 and C1.3, the BTS must be equipped with SUMA The BTS must not contain any G3 TREs for a configuration with more than 12 TREs.
1.2.2 Site Specific Information You must have the following specific information to complete the scenario: At the OMC-R, availability of a workstation, with the server User Name and Password, allowing network configuration Input: customer reports about the final Alcatel-Lucent 9100 BTS configuration (which modules must be replaced).

If all TREs of a cell are impacted: telecom Outage1 C2 and C4: Telecom Outage1 on all cells of the BTS + telecom Outage2 (13 min. to 39 min.) on all cells of downstream BTSs (if any). On Slave BTSs, short telecom outage (all ongoing calls stopped) when the master clock comes back C3: Telecom Outage1 on the impacted cell only (only telecom reduction in the case of secondary sector).
