ADCP-75-159 • Issue 1 • August 2003 • Section 1: Overview 2.2 Enhanced Base Transceiver Station to Host Unit Interface The HU may be interfaced with one or more EBTS’s. Each EBTS provides the RF channel inputs and outputs for a designated sector. Interfacing the HU with multiple EBTS’s will generally require installation of the SMR Interface Panels which are accessory products for the Digivance system. Two types of Interface Panels are available: the Primary Interface Panel and the Expansion Panel.

ADCP-75-159 • Issue 1 • August 2003 • Section 1: Overview At the NOC, control and monitoring of the networked Digivance systems are effected through a Network Element Manager (NEM) interface which requires only a VT100 terminal/emulator for operation. The NEM interface language consists of simple ASCII text strings. All communications are input as either SET or GET commands which result in ASCII text string responses from the specified system or systems.
ADCP-75-159 • Issue 1 • August 2003 • Section 1: Overview signal is digital, the input and output RF signal levels at the HU or the RU are not dependent on the level of the optical signal or the length of the optical fiber. A diagram of the fiber optic transport system for a typical Digivance system is shown in Figure 1-6. The Digivance 20 Watt system does not support reverse path diversity at this time.

Host Unit 2.3 Fault Detection and Alarm Reporting The HU detects and reports various faults including host unit fault, optical fault, power fault, temperature fault, and RF fault. Various front panel Light Emitting Diode (LED) indicators turn from green to red or yellow if a fault is detected.
ADCP-75-159 • Issue 1 • August 2003 • Section 2: Description The host forward path attenuator adjusts the level of the input RF signal to the HU. Using the forward path attenuator, an input signal with a nominal composite signal level of –20 dBm to –40 dBm can be adjusted to produce maximum power output. Additional external attenuation is required if the input signal level is greater than –20 dBm.
ADCP-75-159 • Issue 1 • August 2003 • Section 2: Description 2.11 Cooling Continuous airflow for cooling is provided by dual fans mounted on the right side of the HU housing. A minimum of 3 inches (76 mm) of clearance space must be provided on both the left and right sides of the HU for air intake and exhaust. An alarm is provided if a high temperature condition (>50º C/122º F) occurs. The fans may be field-replaced if either fan fails. 2.
