In this chapter, we will focus on ADSL modem interoperability and DSLAM reliability testing. The interoperability test is used to perform the reliability test. In this test, we use a single modem against different ports of DSLAM to check the performance of each port. This provides information on how reliable DSLAM ports are in the broadband network. We will also focus on wireless-related tests and the emerging WiMax technology.
