Wannan ƙayyadaddun samfurin ya ƙunshi nau'ikan DOCSIS® da EuroDOCSIS® 3.0 na jerin samfuran Modem ɗin Modem ɗin da aka haɗa. Ana iya kiransa da SA120IE. SA120IE an taurare shi da zafin jiki don haɗawa da wasu samfuran da ake buƙata don aiki a cikin yanayin zafi na waje ko yanayin zafi mai tsanani. Dangane da aikin Full Band Capture (FBC), SA120IE ba wai kawai Modem ɗin Cable ba ne, har ma ana iya amfani da shi azaman Spectrum Analyzer (SSA-Splendidtel Spectrum Analyzer). Heatsink wajibi ne kuma takamaiman aikace-aikace ne. An samar da ramukan PCB guda uku a kusa da CPU, don a iya haɗa maƙallin dumama ko na'ura makamancin haka zuwa PCB, don canja wurin zafi da aka samar daga CPU zuwa ga gidaje da muhalli.
