Tellabs Insight Analytics Services' Customer Experience Management (CEM) allows "operators to collect, correlate and deliver actionable information on subscriber behavior and network performance. This capability is enabled by Deep Packet Inspection (DPI). DPI provides effective access to the subscriber data flow at the higher levels of the OSI stack. Simply having access to data is not enough. The analytics engine that consumes all this information is what turns the data into actionable information. CEM is about having access to the right data which is processed efficiently at the right time. With this capability, operators can measure the quality of experience of each subscriber within the context of network performance".
