InterOperability is becoming increasingly important in today?s communication industry. In a time when the consumer has more choice and flexibility in their home networking and Internet services than ever before, single vendor solutions are nearly impossible and most definitely impractical. For this reason manufacturers are taking every precaution to make sure their products work properly with all other manufacturers? products. In this spirit standards bodies are formed with the claim that modems will work collectively if they adhere to the approved standard. However, as with all documents the standards are open to interpretation. This test suite will ensure complete activation phase compliance of a High Bit Rate Digital Subscriber Line- Second Generation modem. The tests are designed to scrutinize the modems adherence to American Nation Standards Industry?s Ti.418-2000 High bit rate Digital Subscriber Line- 2nd Generation (HDSL2) approved standard. All anticipated results are based on this document and the validity of the anticipated results can be proved using this document. The methods of testing are as low level as possible and do not rely on a specific vendor?s product so the most accurate and unbiased results may be obtained.
