Read Me First SCE4812T–MC to SCE4812T Optimization/ATP – continued
5/21/04 1X SC4812T–MC BTS Optimization/ATP 1-5
DRAFT
This workaround is only required before system release
2.16.4.x. After release 2.16.4.x, any one BBX keyed will
enable all the CLPA modules.
NOTE
1–carrier configuration (requires 3 measurements) – The 1-carrier
procedure is identical to the current SC4812T, which is to enable all
three sector BBXs, then measure with each sector with the RF power
meter.
2–carrier configuration (requires 6 measurements) – The procedure
below allows taking measurements with both carriers enabled and more
than one carrier on same sector.
Sector Carrier 1 Carrier 2 Sector Carrier 1 Carrier 2
1 BBX-1 1 BBX-7
2 BBX-2 2 BBX-8
3 BBX-9 3 BBX-3
Procedure:
1. Enable BBX-1 (C1–S1), BBX-2 (C1–S2), and
BBX-9 (C2–S3).
2. Measure TX power from each of all 3 sectors.
3. Disable BBX-1, BBX-2, and BBX-9.
4. Enable BBX-3 (C1–S3), BBX-7 (C2–S1), and
BBX-8 (C2–S2).
5. Measure TX power from each of all 3 sectors.
6. Disable BBX-3, BBX-7, and BBX-8.
3–carrier configuration (requires 9 measurements) – The procedure
below allows taking measurements with all 3 carriers enabled and more
than one carrier on same sector.
