8.2.2.1: fixed line handsets with speech output normally held to the ear must provide magnetic coupling meeting ETSI ES 200 381-1 and carry the T symbol of ETSI ETS 300 381 (TIA-1083-A deemed compliant). 8.2.2.2: wireless devices held to the ear must provide magnetic coupling to hearing technologies meeting ETSI ES 200 381-2 (ANSI/IEEE C63.19 deemed compliant).
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
