ADCP-75-126 • Issue B • April 2002 • Section 1: Overview 2.3 Handset Interface The RU interfaces with the handsets through an antenna. In the reverse path, the RU receives RF signals from each handset. The RU digitizes the RF signals and then converts them to digital optical signals for transport to the HU. In the forward path, the RU receives digital optical signals from the HU. The RU converts the optical signals to RF signals for transmission to the handsets.

ADCP-75-126 • Issue B • April 2002 • Section 1: Overview 3 SYSTEM FUNCTIONS AND FEATURES This section describes various system level functions and features of the Digivance LRCS. 3.1 Fiber Optic Transport On an optional basis, the Digivance LRCS is available either with or without reverse path diversity. On non-diversity systems that do not use a WDM module, the HU is connected to the RU over a pair of single-mode optical fibers. One fiber is used to transport the forward path optical signal.

ADCP-75-126 • Issue B • April 2002 • Section 1: Overview Because separate forward and reverse path optical inputs and outputs are provided at the HU and RU, a Free Space Optics (FSO) system (that meets the Digivance LRCS data rate performance and BER requirements) may be used in applications where it is desirable to bridge an open span and where it is impractical to lay a fiber optic cable.

ADCP-75-126 • Issue B • April 2002 • Section 1: Overview 3.4 Powering The HU is powered by ±24 or ±48 Vdc and must be hard-wired to a local office battery power source through a fuse panel. The RU is powered by 120 or 240 Vac (50 or 60 Hz) and must be hard-wired to the AC power source through a 20 Amp breaker box. The RU is pre-wired for 120 Vac operation but can be converted to 240 Vac operation if required.

ADCP-75-126 • Issue B • April 2002 • Section 2: Description 2.10 Powering The HU is powered by ± 24 or ± 48 Vdc power. The power is fed to the HU through a screwdown type terminal strip located on the rear side of the unit. Power to the HU must be supplied through a fuse panel such as the 20 position PowerWorx fuse panel (available separately). The power circuit for each HU must be protected with a 3 Amp GMT fuse. An On/Off switch is provided on the HU front panel. 2.

In a typical installation, the connectorized end of a mulit-fiber outside plant cable is routed into the enclosure through the cord connector and the individual fibers are broken out into pigtails. The pigtails are connected to the optical ports on the STM and the excess pigtail slack is stored on the fiber storage spool.
