The tests can be any combination of video channel tests and DOCSIS tests such as ranging, registration, throughput or packet loss. The configuration of the tests for the Home Certification test are established in the JDSU Test Productivity Pack (TPP) client along with the appropriate limit plans. The Home Certification test is also capable of performing an Ingress Scan test when configured through the JDSU Test Productivity Pack (TPP).
