USOC Wiring - DSP 4x00 CableAnalyzer

USOC Universal Service Order Code 

Although custom setups can be created in the DSP Series, USOC may trigger a split pair warning. Therefore you may not be able to test USOC wired systems. USOC is not recognized in any of the generic cabling standards such as ANSI/TIA/EIA 568-B, ISO/IEC 11801 and EN50173.
