Integrirana širokopasovna kabelska telekomunikacijska omrežja (CABLE) - Vgrajeni usmerjevalnik
Obstoječi dokument določa temeljni sklop značilnosti, ki napravam z več naročniki omogočajo dostop do storitev hitrega prenosa podatkov, ki jih nudi upravljavec, s pomočjo DOCSIS. Ta temeljni sklop značilnosti omogoča povezljivost z internetom za naprave, ki podpirajo tako IPv4 kot IPv6.
eRouter (elektronski usmerjevalnik) je opredeljen kot naprava z vdelanimi storitvami/aplikacijsko funkcionalna enota (eSAFE), ki se uporablja skupaj z napravo s kabelskim modemom DOCSIS.
Temeljni sklop značilnosti v obstoječem dokumentu vključuje zmožnost oskrbovanja več naprav CPE, opisuje, kako pošiljati podatke v naprave CPE in iz njih, ter zmožnost IP pošiljanja več prejemnikom v naprave CPE in med napravami CPE.
