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.

ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTION 2.5 RF Signal Level Adjustments The HU is equipped with several attenuators for adjusting the signal levels of the forward and reverse path RF signals. The attenuators provide an attenuation adjustment range of 0 to 31 dB and can be set in 1 dB increments. The attenuators are software controlled and are adjusted through the EMS software GUI, NOC/NEM interface, or SNMP interface.

ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTION 2.10 Powering The HU is powered by ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The power is fed to the HU through a screw-down 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 PowerWorx GMT Series 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.

ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTION 5.5 Digivance EMS User Interfaces The Digivance EMS provides three user interfaces: the EMS Graphical User Interface (GUI), the Network Operation Center–Network Element Manager (NOC/NEM) interface, and the SNMP GUI interface. The EMS GUI, the NOC interface, and the SNMP GUI provide the same basic functions. However, the NOC interface and the SNMP GUI cannot be used to download new system software to the Digivance system.

ADCP-75-187 • Issue 1 • September 2005 • Section 2: DESCRIPTION Figure 2-7. NOC/NEM Interface Typical Commands The SNMP interface is a GUI that is used for remote control and monitoring operations (except software download and site number assignment). The SNMP interface uses a Management Information Base (MIB) to define a list of identifiers that are supported by the SNMP agent. The SNMP manager communicates with the SNMP agent over a LAN.
