System Overview Functional Block Diagram 1.1.3 Interface With Cellular Phones The DRUs interface with the cellular phones. In the reverse path, the DRU receives RF signals from each cellular phone. The DRU digitizes the RF signals and then converts them to digital optical signals for transport to the DHU.
ADCP-75-110 • Issue 2B • July 2001 1.1.4 Digital Fiber Optic Transport The DHU is connected to each DRU unit over a pair of multi-mode fiber optic links. One link is used to transport the forward path optical signal. The other link is used to transport the reverse path optical signal. Because the optical signal is digital, no adjustments to the optical signal level are required at the DRU or the DHU regardless of the length of the optical link. Either 50 or 62.
ADCP-75-110 • Issue 2B • July 2001 • Distribution of the digitized forward path RF signals into six digitized optical signals • Conversion of up to six reverse path digitized optical signals to six digitized RF signals • Combining of the six digitized RF signals into a single composite digitized RF signal • Conversion of the combined digitized RF signal to a composite RF signal • DC power for powering the DRUs • Relay contact closures to provide alarm information to an external alarm system 17.
ADCP-75-110 • Issue 2B • July 2001 1.2.3 Fault Detection and Alarm Reporting The DHU is designed to detect internal circuitry faults and optical port faults. Various front panel Light Emitting Diode (LED) indicators turn from green to red or yellow if a fault is detected or an optical input is lost. A set of alarm contacts (normally open and normally closed) are also provided for reporting an alarm to an external alarm system when a fault is detected.

ADCP-75-110 • Issue 2B • July 2001 1.3.3 Fault Detection The DRU is designed to detect internal circuitry faults or loss of system inputs. A front panel LED indicator turns from green to red when a fault condition is detected or when the optical input is lost. The DRU sends the fault information to the DHU or DEU over the fiber optic link. A corresponding port LED at the DHU or DEU turns from green to red when the DRU reports a fault. 1.3.

ADCP-75-110 • Issue 2B • July 2001 2 INSTALLATION PLANNING AND SYSTEM DESIGN 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. 2.
ADCP-75-110 • Issue 2B • July 2001 The LIU is rack or wall mountable and is powered by 120–240 Vac (50–60 Hz) power. Refer to the Digivance Local Interface Unit User Manual (ADCP-75-113) for a complete description of the LIU. 2.1.2 Remote BTS (Cell Site Base Station) Interface A remote interface between the DHU and the BTS (cell site base station) via a donor antenna requires specific RF input and output signal levels at the DHU and antenna.
ADCP-75-110 • Issue 2B • July 2001 2.2 Location and Mounting Requirements 2.2.1 DHU and DEU Location and Mounting Requirements The DHU and the DEU may be either rack mounted or wall mounted. Fasteners (both metric and US standard) are included with each unit for rack mount applications. A pair of reversible mounting brackets is provided that allows the unit to be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack.
ADCP-75-110 • Issue 2B • July 2001 2.3 Powering Requirements 2.3.1 DHU and DEU Powering The DHU and DEU are powered by 120–240 Vac (50–60 Hz) which is supplied through a standard three-conductor AC power cord. The 120 Vac power cord is provided with the unit and is 98 inches (2.5 m) long. Both the DHU and the DEU have a current rating of 2.0 Amps at 120 Vac input. Locate each unit so that an AC outlet is within the reach of the power cord.
ADCP-75-110 • Issue 2B • July 2001 2.4 Optical Options and Requirements Each DHU and its associated DEUs and DRUs are connected over a pair of fiber optic links. One link transports the forward path optical signal and the other link transports the reverse path optical signal. Either 50 or 62.5 micron core multi-mode fiber optic cable may be used for the optical link. If 50 micron cable is used, the optical link may be up to 750 meters (2461 ft) in length. If 62.
ADCP-75-110 • Issue 2B • July 2001 Whenever possible, use conduit or a guideway such as the FiberGuide system to route the optical links between the DHU, the DEUs, and the DRUs. Avoid routing optical fibers through ladder type cable racks or troughs that do not provide sufficient support to limit bending or prevent accidental damage. Tie-wrapping is not recommended as a means of securing fiber optic cables. Provide sufficient slack at each unit for connecting each fiber to the required port.

ADCP-75-110 • Issue 2B • July 2001 2.10 Maintenance Requirements The Digivance ICS requires no regular maintenance to insure continuous and satisfactory operation. Maintenance, as it applies to the Digivance ICS, primarily involves diagnosing and correcting service problems as they occur. Faults and failures arising from within the Digivannce ICS will generate an external alarm response which includes lighting an LED indicator(s) and closing or opening a set of alarm contacts.
ADCP-75-110 • Issue 2B • July 2001 building personnel for an initial approval/confirmation. This gives a good estimate of the extent of the system work needed. Occasionally, some of the system design work can be accomplished at this point. 2.11.
ADCP-75-110 • Issue 2B • July 2001 2. Install a DRU as described in the Digital Remote Unit Installation Instructions (ADCP 75-112). If a donor antenna is used, install the DHU and RIU close to the donor antenna. 3. Conduct an initial performance evaluation and complete the following: a) Confirm proper isolation, signal quality, and power levels. b) Make test calls from DRU service area and evaluate call quality (confirm with service provider if desired). c) Address performance issues as needed. 4.
