    SINGLE BAND SYSTEM OVERVIEW The Digivance single band SMR 800 MHz LRCS is an RF signal transport system that provides long-range RF coverage in areas where it is impractical to place a Base Transceiver Station (BTS) at the antenna site.

    RU. In the reverse path, the HU receives digital optical signals from the RU. The HU converts the digital optical signals back to RF signals for transmission to the BTS. Page 1-2 © 2002, ADC Telecommunications, Inc.

  • Page 14: Handset Interface

    The primary component of the remote NOC interface is a PC-type desktop computer loaded with the Digivance Element Management System (EMS) software. In addition to the local management functions described in the previous section, the EMS also provides the various control and monitoring functions required for remote management of multiple LRSC systems through a NOC.

    This section describes various system level functions and features of the Digivance LRCS. 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.

    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.
