a) Straight-through uses the same standard; crossover uses different standards
በቀጥተኛ ኬብል (straight-through cable) ውስጥ፣ በኬብሉ በሁለቱም ጫፎች ላይ ያሉት ሽቦዎች በተመሳሳይ ቅደም ተከተል የተገናኙ ናቸው (ለምሳሌ፣ ሁለቱም ጫፎች T568A ወይም T568B ደረጃን ይጠቀማሉ)። ይህ ማለት የፒን አቀማመጥ በሁለቱም ጫፎች ላይ ተመሳሳይ ነው።
በክሮስኦቨር ኬብል (crossover cable) ውስጥ ግን፣ በኬብሉ በሁለቱም ጫፎች ላይ ያሉት ሽቦዎች በተለያየ ቅደም ተከተል የተገናኙ ናቸው። በተለምዶ አንድ ጫፍ T568A ደረጃን ሲጠቀም ሌላኛው ጫፍ ደግሞ T568B ደረጃን ይጠቀማል፣ ይህም የተወሰኑ የመላኪያ (transmit) እና የመቀበያ (receive) ሽቦዎችን ያቋርጣል።
ይህ ልዩነት ኬብሎቹ የተለያዩ አይነት መሳሪያዎችን (ለምሳሌ ኮምፒውተርን ከስዊች ጋር) ወይም ተመሳሳይ አይነት መሳሪያዎችን (ለምሳሌ ኮምፒውተርን ከኮምፒውተር ጋር) ለማገናኘት ያስችላቸዋል።
