VDSL2 profile (Frequency Plan)
Eight VDSL2 frequency profiles (8a, 8b, 8c, 8d, 12a, 12b, 17a, and 30a) are defined in G.993.2. Each profile covers certain settings and parameters, such as maximum aggregate transmit power. The higher-frequency profiles (17a and 30a) are mostly used to deliver high speed at shorter distances.
