Home Certification test (optional purchase required) is a user configured combination of tests. The tests can be any combination of testing on video channels and DOCSIS tests such as ranging, registration, throughput or packet loss. The configuration of the tests for the certification option are established in the JDSU Test Productivity Pack (TPP) client along with the appropriate limit plans. The closeout test option also provides an automated sequence of steps that guides the technician through the entire process.
