CTI
CTI turns up in 2 fields: electrotechnology, telecom & it. Here is what it means to the people in each one.
CTI in electrotechnology
Comparative tracking index: voltage an insulating material withstands before tracking under a wet contamination test.
CTI, comparative tracking index, is found by dripping ammonium chloride solution between two electrodes on a sample and recording the highest voltage at which it survives 50 drops without forming a conductive track. Materials fall into groups: I (600 V and above), II (400 to below 600 V), IIIa (175 to below 400 V) and IIIb (100 to below 175 V). A better group permits shorter creepage distances, so CTI drives the choice of plastics and laminates.
"Standard FR-4 lands in group IIIa, if you want group I creepage figures, buy a high-CTI laminate."
CTI in telecom & it
Computer telephony integration links phone systems with software applications.
Computer telephony integration connects a PBX or telecom switch to computer systems. It allows software to control call routing, trigger screen pops with caller information, and manage automatic dialers. Call centers rely on this technology to bridge their voice infrastructure with customer relationship databases, making agents more efficient.
"The new CRM rollout is failing because the CTI link keeps dropping the agent screen pops."
