Term or Abbreviation Definition

RGD Remote Global Positioning System (GPS) Distribution

SCCP Small CDMA Channel Processor. The type of CCP shelf used in the SC4812ET

Lite BTS.

test equipment set The CDMA LMF computer, communications test set, directional couplers,

attenuators, termination loads, associated test cables, and adapters needed for the

complete calibration and acceptance testing of a BTS. The test equipment set is

calibrated and maintained as a unit. When one component of a set is replaced, the

complete set must be recallibrated to ensure measurement errors are not

introduced during BTS optimization and ATP.

TCP Temperature Compensation Panel. A function of the SC4812ET Lite MAP which

provides the capability to adjust DC voltage output of the rectifiers to compensate

for variations resulting from temperature changes.

TRDC Transmit & Receive Dual Directional Coupler (Non–duplexed, Receive Filter).

TRDCs contains separate transmit and receive paths and bandpass filters which

are not connected electrically. Transmit and receive antenna signals are not

duplexed and must be handled by separate antennas. Each RF path contains a dual

directional coupler on the antenna port which allows sampling of antenna signals

in the forward (transmit) and reflected (receive) directions for use by an RFDS.
