3.2 Control and Monitoring Software
The Digivance CXD EMS or customer supplied NMS using the Digivance CXD/NXD SNMP
Agent is used to provision and configure the system for operation. This includes initializing the
system, setting up the Hub and RAN element identification schemes, tenant processing, setting
alarm thresholds, and setting forward and reverse path RF gain adjustments. The EMS or NMS
software is also used to get alarm messages (individual or summary), data measurements, or to
upgrade the Hub/RAN system software. All control and monitor functions can be effected
using either the EMS or through a NMS.
3.3 Fault Detection and Alarm Reporting
LED indicators are provided on each of the respective modules populating the Hub Digital
Chassis, RF Chassis and RAN Chassis to indicate if the system is normal or if a fault is
detected. In addition, a dry contact alarm interface can be provided as an accessory item that is
managed by the EMS software with normally open and normally closed alarm contacts for
connection to a customer-provided external alarm system. All Hub and RAN alarms can be
accessed through the SNMP manager or the EMS software GUI.
3.4 Powering
The Hub Digital and RF Chassis are powered by -48 Vdc and must be hard-wired to a local
office battery power source through a fuse panel. The power consumption of the system will
depend on the configuration of the system and how the Digital Chassis and RF Chassis are
populated.
Table 1-1 lists the typical power consumption of the respective modules for the Digital
Chassis.
Table 1-1. Digital Chassis Power Consumption
MODULE POWER
Digital Chassis 76.0 Watts
CPU 20.5 Watts
STF2 3.5 Watts
SIF 15.5 Watts
RSC 9.0 Watts
For a standard configuration of 4:1 simulcasting, Table 1-2 lists the estimated power
consumption for the Digital Chassis
