Tests ADSL TR-067


The Technical report TR-067 has been written by Broadband Forum experts. It provides a set of test methods to verify the transceiver functional requirements and the physical layer performances of an ADSL modem implemented in accordance with ITU-T G.992.1. Higher layer functionality test cases are also defined in this document.
An ADSL system consists of DSLAMs, filters and splitters located at both ends of the local loop, and CPE modems.
These systems are tested for dynamic interoperability on a set of loops and noise conditions which allows a large covering of loop conditions representative of network operator’s deployments.
