| Description | Regional settings for a 2BASE-TL PME, as specified in the
relevant Regional Annex of [G.991.2].
Regional settings specify the Power Spectral Density (PSD)
mask and the Power Back-Off (PBO) values, and place
limitations on the max allowed data rate, power, and
constellation.
Possible values for this object are:
region1 - Annexes A and F (e.g., North America)
region2 - Annexes B and G (e.g., Europe)
Annex A/B specify regional settings for data rates 192-2304
Kbps using 16-TCPAM encoding.
Annex F/G specify regional settings for rates 2320-3840 Kbps
using 16-TCPAM encoding and 768-5696 Kbps using 32-TCPAM
encoding.
If a Clause 45 MDIO Interface to the PME is present, then this
object partially maps to the Region bits in the 2B general
parameter register. |
