Chosinthira cha Fiber Node, SA120IE
Kufotokozera Kwachidule:
Mafotokozedwe a malonda awa akuphatikizapo mitundu ya DOCSIS® ndi EuroDOCSIS® 3.0 ya mndandanda wa zinthu za Embedded Cable Modem Module. Pogwiritsa ntchito chikalatachi, chidzatchedwa SA120IE. SA120IE ndi yolimba kutentha kuti iphatikizidwe muzinthu zina zomwe zimafunika kugwira ntchito panja kapena kutentha kwambiri. Kutengera ntchito ya Full Band Capture (FBC), SA120IE si Cable Modem yokha, komanso ingagwiritsidwe ntchito ngati Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). Heatsink ndi yofunikira komanso yofunikira kugwiritsa ntchito. Mabowo atatu a PCB amaperekedwa mozungulira CPU, kotero kuti bracket yotenthetsera kapena chipangizo chofanana nacho chikhoza kumangiriridwa ku PCB, kuti kutentha komwe kwapangidwa kuchokera ku CPU kusunthire kupita ku nyumba ndi chilengedwe.

Kusintha kwa dalaivala wa UART/I2C/SPI/GPIO kuti azitha kuyang'anira zipangizo zosiyanasiyana. Monga Fiber node, Power Supply, RF Amplifier
▶Docsis MIBs / Thandizo lina lililonse la MIB lopangidwa mwamakonda
▶Open system API ndi kapangidwe ka deta ya 3rdmwayi wopeza pulogalamu ya chipani
▶Kuzindikira chizindikiro cha mphamvu yochepa. Chizindikiro chochepera -40dBmV chidzawonetsedwa ndi Spectrum Analyzer yomangidwa mkati
Mafayilo a ▶CM MIB atsegulidwa kwa makasitomala
▶CM management Web GUI ikupezeka pa WAN kapena LAN
▶MSO ikhoza kuyambitsanso CM patali kudzera pa Telnet kapena SNMP
▶Ingasinthidwe pakati pa Bridge ndi Router mode
▶Imathandizira kukweza MIB ya chipangizo cha DOCSIS

Woyang'anira Wakunja
Woyang'anira wakunja amagwiritsidwa ntchito kuonetsetsa kuti makinawo akugwira ntchito moyenera. Woyang'anira akukankhidwa ndi
Firmware nthawi ndi nthawi, kuti CM isakhazikitsenso. Ngati pali vuto ndi CM
Firmware, kenako pakatha nthawi inayake (nthawi yoyang'anira), CM idzayambiranso yokha.
