ADCP-75-187 • Issue 3 • September 2006 • Section 1: OVERVIEW 2.2 Enhanced Base Transceiver Station Interface The HU is interfaced with an EBTS over coaxial cables as shown in Figure 1-2. The EBTS provides the RF channel inputs and outputs for a designated sector. In the forward path, the HU receives two RF inputs from the EBTS. The HU digitizes the RF spectrum and then converts it to digital optical signals for transport to the RU. In the reverse path, the HU receives digital optical signals from the RU.

To support the SNMP interface, a PC-type computer loaded with both the Digivance Element Management System (EMS) software and the SNMP Proxy Agent software is required.
ADCP-75-187 • Issue 3 • September 2006 • Section 1: OVERVIEW 3 SYSTEM FUNCTIONS AND FEATURES This section describes various system level functions and features of the Digivance system. 3.1 Fiber Optic Transport In a typical Digivance LRCS system, the HU is connected to the RU over two single-mode optical fibers. One fiber is used to transport the forward path optical signal. The other fiber is used to transport the reverse path optical signal.
ADCP-75-187 • Issue 3 • September 2006 • Section 1: OVERVIEW 3.2 Control and Monitoring Software The EMS software and the SNMP Proxy Agent software provide control and monitoring functions for the Digivance system through the local, NOC, and SNMP interfaces. The EMS software package supports the local and NOC interfaces but does not include the SNMP Proxy Agent software which must be ordered separately. Both the EMS and the SNMP Proxy Agent software are required to support the SNMP interface.
ADCP-75-187 • Issue 3 • September 2006 • Section 1: OVERVIEW 4 DUAL-BAND REMOTE UNIT SCS SYSTEMS Sections 1 through 3 described the functions and features of a typical SCS system equipped with one HU and the single-band RU. Each single-band RU is equipped with the electronics to support one frequency band. If it is necessary to support two frequency bands (such as 800/900 MHz SMR and 1900 MHz) at the same remote location, a dual-band RU can be deployed.
