Juon cable in network eo ejjab test ej melelen bwe kwojjab jelā elañe emaron in jilkinlok HD video signal ko, elañe emaron jerbal iumin PoE power mode, ak elañe ewor break ko ak interference source ko ilo lukwon. Ilo security cabling engineering, network testing ejjab juon 'extra step' — ej line in defense eo eliktata ñan delivery quality.
