Alarm Reporting
ThecircuitboardprovidesalarmreportingfortheUninterruptiblePowerSupply(UPS).The
followingalarmsaresupported:
•LowBattery
•BatteryMissing
•ReplaceBattery
•OnBattery
SBU ONT Interfaces
TheSBUONTsupportsthefollowinginterfaces:
•Eight(8)POTS
•Four(4)DS1
•Two(2)10/100/1000Base‐TEthernetConnections
•Power
Ethernet Interface
TheSBUONTsupportsdataservicesthroughtwo10/100/1000Base‐TEthernetinterfacesvia
RJ‐45connectors.TheEthernetinterfacemeetsIEEE802.3specificationsandistransformer
coupledfor1500Visolation.Bothfullandhalfduplexmodesaresupported.
TheSBUONTalsosupportsvideoserviceviatheEthernetthroughthe
ETH 2interface.
POTS Interface
TheSBUONTsupportsbasictelephoneservicethrougheightPOTSinterfaces.Eachinterface
issupportedbyanRJ‐11jackfortesting.ThePOTSInterfacefeaturesetislistedbelow:
