ADCP-75-179 • Preliminary Issue A • September 2004 • 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 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.
PAGE 20
ADCP-75-179 • Preliminary Issue A • September 2004 • Section 1: Overview In some applications, it may be desirable or necessary to combine the forward and reverse path optical signals from multiple HU’s and RU’s onto a single optical fiber. This can be accomplished by using an active Coarse Wavelength Division Multiplexer (CWDM) system. Up to four Digivance systems may be configured to operate over a single optical fiber. A CWDM module is mounted with each HU and RU.
PAGE 21
ADCP-75-179 • Preliminary Issue A • September 2004 • 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 and SNMP Proxy Agent software are stored on CD-ROM’s which are shipped in a separate package along with the software user manuals.

ADCP-75-179 • Preliminary Issue A • September 2004 • 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-75-179 • Preliminary Issue A • September 2004 • Section 2: Description 2.11 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.
