RIU or the LIU. Additional information concerning the DHU to BTS interface is provided in the Digivance ICS Remote Interface Unit User Manual (ADCP-75-113) and in the Digivance ICS Local Interface Unit User Manual (ADCP-75-114).
ADCP-75-110 • Issue 2B • July 2001 1.3 Digital Remote Unit Description The DRU, shown in Figure 4, serves as the cellular user servicing unit for the Digivance ICS. The DRU provides the following basic functions: • RF interface to the cellular users via an external antenna •...
Page 16
The RF signal interface between the DRU and the cellular users is provided through an external antenna connected to a female SMA connector. The antenna must be ordered separately. Several types of antennas with various RF propagations are available. Non-ADC antennas may also be used with the DRU to meet various application requirements.
1.4 Digital Expansion Unit Description The DEU, shown in Figure 6, serves as a service expansion unit and line extender for the Digivance ICS. The DEU provides the following basic functions: • Optical interface to the DHU and up to six DRUs or DEUs •...
An alarm signal transported over the fiber optic link. Unit Alarm A fault within a unit that usually affects all connected ports. 1.6 Specifications Refer to Table 5 for the Digivance ICS system specifications. All specifications apply after five minute warm-up period. Table 5. System Specifications PARAMETER...
This section provides installation planning information and basic system design recommendations for RF engineers that will be designing and installing an in-building coverage solution using the Digivance ICS. System design and planning services are available from ADC if required. Refer to Section 6 of this manual for additional information.

The ceiling mount hallway antenna is designed to mount in the center of long corridors. Antennas other than those offered by ADC may also be used if required. Note: To comply with Maximum Permissible Exposure (MPE) requirements, antennas must be installed to provide at least 20 centimeters (8 inches) of separation from all persons per FCC 47 CFR part 2.1091.
Follow a systematic process when designing an in-building coverage solution. The following sub sections outline the four phases of the in-building coverage solution design process. System design and planning services are available from ADC if required. Refer to Section 6 of this manual for additional information.
1. Install the DHU as described in Section 3 of this manual and adjust the RF interface levels based on the system design specifications. Additional information concerning the DHU to BTS interface is provided in the Digivance ICS Remote Interface Unit User Manual (ADCP-75-113) and in the Digivance ICS Local Interface Unit User Manual (ADCP-75-114).
