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
software package supports the local and NOC interfaces but does not include the SNMP Proxy
Agent software which must be ordered separately. Both the EMS and the SNMP Proxy Agent
software are required to support the SNMP interface. All software files are provided on CD-
ROM’s. Software installation consists of copying the software files from the CD-ROM’s to a
designated directory on the hard-drive of the EMS computer.
The EMS software provides the capability to provision and configure the Digivance system for
operation. This includes selecting a site name, setting alarm thresholds, and setting forward and
reverse path RF gain adjustments. The EMS software also provides the capability to get alarm
messages (individual or summary), obtain data measurements, and to upgrade the HU/RU
system software. All control and monitor functions (except software upgrade which is not
supported by the NOC/NEM and SNMP interfaces and HU/RU pair site number assignment
which is not supported by the SNMP interface) may be implemented using the NOC/NEM
interface, the SNMP interface, or the EMS software GUI.
3.3 Fault Detection and Alarm Reporting
LED indicators are provided on the front panel of the HU and on the underside of the RU to
indicate if the system is normal or if a fault is detected. In addition, normally open and normally
closed alarm contacts (for both major and minor alarms) are provided at the HU for connection
to a customer-provided external alarm system. All alarms can also be accessed through the
NOC/NEM interface, SNMP manager, or the EMS software GUI.
3.4 Powering
The HU is powered by ±24 or ±48 VDC and must be hard-wired to a local DC power source
through a fuse panel. A screw-down terminal strip is provided on the rear side of the HU for the
power connections.
The RU is powered by 90 to 265 VAC (nominal 120 or 240 VAC), 47 to 63 Hz power. On an
optional basis, the RU may be powered by 60 to 89 VAC, 47 to 63 Hz power. A connector is
provided on the underside of the RU for the AC power connections. A 3-wire AC power cable
rated for outdoor use is included with the RU. The stub end of the cable must be hard-wired to
the AC power source.
3.5 Equipment Mounting and Location
The HU consists of a rack-mountable chassis assembly that is designed for mounting in a non-
condensing indoor environment such as inside a wiring closet or within an environmentally-
controlled cabinet. The HU is usually installed within 20 feet of the EBTS and may be mounted
in either a 19- or 23-inch, WECO or EIA, equipment rack.
The RU consists of a sealed aluminum enclosure designed for mounting in either an indoor or
outdoor environment. The RU may be mounted from a pole or the exterior side of a building
with the standard mounting bracket or from a strand with an accessory bracket.
