Babban raison IS215VCMIH2C shine don ba da dama da sarrafa hadadden tsarin sadarwa na tsarin TMR. Gine-ginensa an tsara shi bisa ƙa'idar sakewa da wariya.

2.1 Tsarin gine-ginen IONet guda uku
Mafi ma'anar fasalin IS215VCMIH2C shine tashoshin jiragen ruwa na 10Base2 IONet masu zaman kansu guda uku. A cikin tsarin TMR, masu sarrafawa daban-daban guda uku (wanda aka zaɓa R, S, da T) suna aiki a layi daya. IS215VCMIH2C tana ba kowane mai sarrafawa da nasa tashar IONet mai sadaukarwa.

• Hannun Hannun Bayanai Mai Rarraba: IONet-R, IONet-S, da IONet-T cibiyoyin sadarwa ne daban-daban. Wannan rarrabuwa yana tabbatar da cewa kuskure, kamar gajere ko buɗaɗɗen da'ira, akan hanyar sadarwa ɗaya baya tasiri hanyar sadarwar sauran tashoshi biyu masu sarrafawa.

• Daidaita Bayanan Samun da Sarrafa: Kowane mai sarrafawa a cikin saitin TMR yana karanta bayanan shigarwa da kansa daga IONet ɗin da aka keɓe kuma yana rubuta umarnin fitarwa zuwa cibiyar sadarwa iri ɗaya. IS215VCMIH2C a cikin kowane I/O rack yana sauraron duk hanyoyin sadarwa guda uku a lokaci guda, yana ba da damar I/O na rak ɗin yin hidimar duk tashoshi uku masu sarrafawa da kansu.

2.2 Ƙwararriyar Bus ɗin VME a cikin Muhalli Mai Raɗaɗi
Yayin da IONets ke ware, ana raba jirgin baya na VME. IS215VCMIH2C tana aiki a matsayin mai kula da bas, amma rawar da take takawa ba ta da kyau a cikin saitin TMR wanda ya ƙunshi taragu da yawa.
