ADCP-75-169 Issue 1 June 2004 1 INTRODUCTION The rear access Host Unit serves as the EBTS servicing unit for the Digivance LRCS system. A typical LRCS system consists of a Host Unit (HU) and a Remote Unit (RU). The HU consists of an electronic chassis assembly that mounts in a standard equipment rack. The RU consists of multiple electronic and optical modules that mount in either an outdoor cabinet or an indoor mounting shelf. The HU and the RU together comprise an LRCS system. Various acces

ADCP-75-169 Issue 1 June 2004 2.2 RF Signal Connections The RF signal connections between the HU and the EBTS are supported through either two (non-diversity unit) or three (diversity unit) N-type female connectors. On non-diversity units, one connector is used for the forward path RF signal. The other connector is used for the reverse path RF signal. On diversity units, a third connector is used for the diversity path RF signal. In installations where multiple EBTS’s will be connected to a

ADCP-75-169 Issue 1 June 2004 When routed to the RU outdoor cabinet, the OSP fiber optic cable should be spliced to a connectorized outdoor-rated cable (consisting of individual jacketed pigtails) which is then routed into the outdoor cabinet. The individual pigtails can then be connected directly to the STM optical ports. A connector is provided on the bottom of the RU outdoor cabinet to seal the cable entry point and provide strain relief. The procedure for routing the fiber cable into an
