Definition
PDA Power Distribution Assembly.
Assembly in an SC4812T Lite BTS providing internal DC Power Distribution and
Circuit Protection.
RFMF RF Modem Frame
RGD Remote Global Positioning System (GPS) Distribution
Module that provides distribution of Digital Timing Information to up to four BTS RF
Modem Frames from a single Remote GPS Receiver.
RGPS Remote Global Positioning System
GPS Receiver and Signal Distribution Subsystem that provides Digital Timing
Information for up to four BTS RF Modem Frames at a Cell Site.
RGPS Expansion
Primary Frame
BTS Frame where the RGD is located and that 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 that receives RGPS Digital Timing Signals distributed from the Primary
RGPS Expansion Frame at a Cell Site.
RHSO Remote High–Stability Oscillator
Subsystem that generates and distributes Synchronization Signals from a single HSO to
up to four RF Modem Frames.
SCCP Small CDMA Channel Processor
The type of SCCP Cage used in the SC4812ET Lite BTS.
TRF Transmit and Receive Filter
TRFs contains separate Transmit and Receive Paths and Bandpass Filters that are not
connected electrically.
Transmit and Receive Antenna Signals are not duplexed and must be handled by separate
antennas.
Each RF Path may contain a Dual Directional Coupler on each Antenna Port that allows
sampling of Antenna Signals in the Forward (Transmit) and Reflected (Receive)
Directions for use by an RFDS.
