, ▁Do D ▁functions . ▁ ▁SV ▁products ▁focus ▁on ▁specific ▁physical ▁systems ▁with ▁specific ▁physical ▁( ge ographical ) ▁locations . ▁The ▁relationship ▁between ▁architecture ▁data ▁elements ▁across ▁the ▁SV ▁to ▁the ▁O V ▁can ▁be ▁exempl ified ▁as ▁systems ▁are ▁proc ured ▁and ▁field ed ▁to ▁support ▁organizations ▁and ▁their ▁operations . ▁ ▁The ▁Do D AF ▁V 1 . 5 ▁SV ▁products ▁are : ▁ ▁SV - 1 ▁Systems / Services ▁Interface ▁Description ▁ ▁Dep ict s ▁systems ▁nodes ▁and ▁the ▁systems ▁resident ▁at ▁these ▁nodes ▁to ▁support ▁organizations / human ▁roles ▁represented ▁by ▁oper ational ▁nodes ▁of ▁the ▁O V - 2 . ▁SV - 1 ▁also ▁ident ifies ▁the ▁interfaces ▁between ▁systems ▁and ▁systems ▁nodes . ▁ ▁SV - 2 ▁Systems / Services ▁Communic ations ▁Description ▁ ▁Dep ict s ▁pert inent ▁information ▁about ▁communic ations ▁systems , ▁communic ations ▁links , ▁and ▁communic ations ▁networks . ▁ ▁SV - 2 ▁documents ▁the ▁kinds ▁of ▁communic ations ▁media ▁that ▁support ▁the ▁systems ▁and ▁implements ▁their ▁interfaces ▁as ▁described ▁in ▁SV - 1 . ▁Thus , ▁SV - 2 ▁shows ▁the ▁communic ations ▁details ▁of ▁SV - 1 ▁interfaces ▁that ▁autom ate ▁aspects ▁of ▁the ▁need lines ▁represented ▁in ▁O V - 2 . ▁ ▁SV - 3 ▁Systems - System s , ▁Services - System s , ▁Services - Services ▁Mat rices ▁ ▁provides ▁detail ▁on ▁the ▁interface ▁characteristics ▁described ▁in ▁SV - 1 ▁for ▁the ▁architecture , ▁arranged ▁in ▁matrix ▁form . ▁ ▁SV - 4 a
