Tlhaloso e Khutšoanyane:
Tlhaloso ena ea sehlahisoa e akaretsa mefuta ea DOCSIS® le EuroDOCSIS® 3.0 ea letoto la lihlahisoa tsa Embedded Cable Modem Module. Ka har'a tokomane ena, e tla bitsoa SA120IE. SA120IE e thatafalitsoe mochesong bakeng sa ho kopanngoa lihlahisoa tse ling tse hlokahalang ho sebetsa tikolohong ea kantle kapa mocheso o feteletseng. Ho latela ts'ebetso ea Full Band Capture (FBC), SA120IE ha se Cable Modem feela, empa hape e ka sebelisoa e le Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). Heatsink ke ea tlamo ebile e ikhethile ka ts'ebeliso. Ho fanoa ka masoba a mararo a PCB ho potoloha CPU, e le hore bracket ea heatsinking kapa sesebelisoa se tšoanang se ka khomareloa ho PCB, ho fetisetsa mocheso o hlahisoang hole le CPU le ho ea ntlong le tikolohong.
