A91750.102​ ​RF​ ​Channel​ ​Monitor Description The​ ​A91750.102​ ​RF​ ​Channel​ ​Monitor​ ​is​ ​designed​ ​for​ ​automatic monitoring​ ​of​ ​RF​ ​line-ups​ ​in​ ​headends​ ​and​ ​hubs​ ​in​ ​a​ ​CATV-network. The​ ​A91750.102​ ​RF​ ​Channel​ ​Monitor​ ​scans​ ​and​ ​supervise​ ​up​ ​to​ ​200 channels​ ​in​ ​the​ ​frequency​ ​range​ ​46-860​ ​MHz​ ​at​ ​very​ ​high​ ​speed. (<100​ ​ms/channel). The​ ​RF​ ​signals​ ​can​ ​be​ ​either​ ​analog​ ​TV,​ ​FM​ ​Radio​ ​or​ ​Digital Channels​ ​(QAM,​ ​QPSK,​ ​COFDM)​ ​or​ ​any​ ​of​ ​32​ ​different​ ​modulation types. The​ ​A91750.102​ ​can​ ​be​ ​managed​ ​via​ ​a​ ​standard​ ​SNMP​ ​protocol​ ​by Cisco​ ​ROSA​ ​TM​ ​NMS​ ​Network​ ​Management​ ​System, Innocom-arcodan​ ​NMS​ ​or​ ​any​ ​standard​ ​MIB-browser. It​ ​is​ ​completely​ ​user​ ​configurable​ ​and​ ​can​ ​be​ ​programmed​ ​to​ ​report two​ ​levels​ ​of​ ​alarms​ ​per​ ​measured​ ​carrier​ ​indicating​ ​loss of​ ​performance​ ​or​ ​breakdown​ ​of​ ​the​ ​network​ ​or​ ​hub. It​ ​can​ ​be​ ​accessed​ ​remotely​ ​via​ ​internet​ ​or​ ​via​ ​local​ ​server.

Features

● ● ● ● ● ● ●

Monitors​ ​analog​ ​RF​ ​(vision),​ ​QAM,​ ​QPSK,​ ​COFDM​ ​and​ ​FM​ ​carriers​ ​with superior​ ​level​ ​accuracy. Supports​ ​multi-standard,​ ​multi-system​ ​(BG/I/DK/MN). Generates​ ​necessary​ ​triggers​ ​for​ ​automatic​ ​redundancy​ ​switching​ ​of modulators. Instant​ ​alarm​ ​notification​ ​results​ ​in​ ​significant​ ​reduction​ ​of​ ​outage​ ​time. Proactive​ ​alarm​ ​reporting​ ​improves​ ​the​ ​up-time​ ​of​ ​the​ ​network​ ​for​ ​better customer​ ​satisfaction. Signal​ ​quality​ ​measurements​ ​report​ ​the​ ​health​ ​status​ ​and​ ​network performance​ ​continuously. Intelligent​ ​alarm​ ​reporting:​ ​Groups​ ​different​ ​alarms​ ​into​ ​one​ ​or​ ​more accurate​ ​messages​ ​giving​ ​more​ ​precise​ ​information​ ​to​ ​the​ ​operator​ ​for more​ ​efficient​ ​response​ ​to​ ​the​ ​technical​ ​staff.
