Table 1-2: Non–Standard Terms and Abbreviations
Term or
Abbreviation
Definition
HSOX HSO Expansion. Module used in a BTS expansion frame to interface with the starter
frame HSO or LFR and distribute the timing signals to the expansion frame CSM
modules.
ISC In–Service Calibration. Technique for performing calibration sector by sector on a BTS
to avoid completely removing the site from service.
LPAC Linear Power Amplifier Controller
LFR2 Low Frequency Receiver, second generation. Low–cost LFR card with capability to
distribute synchronization signals to multiple RF modem frames.
MAP Meter Alarm Panel. SC4812ET Lite Field Replaceable Unit (FRU) which contains the
functions of both the Temperature Compensation Panel (TCP) and the DMAC. Term is
used interchangeably with DMAC.
MCC8E Multichannel CDMA Card supporting 8 IS–95A/B channels.
MCC24E Multichannel CDMA Card supporting 24 IS–95A/B channels.
MCC–1X Multichannel CDMA Card supporting 16 or 48 CDMA2000 1X or (with Software
Release 2.16.0.84.3 and higher) IS–95A/B channels.
MPC Multi–coupler Preselector Card. BTS CCP shelf module used to amplify and distribute
RX signals to BBX modules.
NECB Network Element Configuration Baseline
NECF Network Element Configuration File
NECJ Network Element Configuration Journal
OLF Object List File. File containing a list of the ROM and RAM code versions which should
be operating on every device installed in a BTS. The file is resident on the Central Base
Station Controller (CBSC) Mobility Manager (MM) and is passed to the GLI after a
DLM job is invoked. The GLI uses the OLF to determine which devices require code
download to meet the OLF–specified version.
PDA Power Distribution Assembly. Assembly in an SC4812ET Lite BTS providing internal
DC power distribution and circuit protection.
RFMF RF Modem Frame
RGD Remote Global Positioning System (GPS) Distribution. Module which provides
distribution of digital timing information to up to four BTS RF modem frames (RFMFs)
from a single Remote GPS receiver.
RGPS Remote Global Positioning System. GPS receiver and signal distribution subsystem
which provides digital timing information for up to four BTS RFMFs at a cell site.
RGPS expansion
primary frame
BTS frame where the RGD is located and which serves as the distribution point for
RGPS digital timing signals to other (secondary) BTS frames at a cell site.
RGPS expansion
secondary frame
BTS frame which receives RGPS digital timing signals distributed from the primary
RGPS expansion frame at a cell site.
RHSO Remote High–Stability Oscillator. Subsystem which generates and distributes
synchronization signals from a single HSO to up to four RF modem frames.
