This table supports definitions of administrative and operating Profiles for 2BASE-TL PMEs. First 14 entries in this table SHALL always be defined as follows (see 802.3ah Annex 63A): Profile Rate Power Region Constellation index (Kbps) (dBm) (G.991.2) 1 512 13.5 1 16-TCPAM (default) 2 704 13.5 1 16-TCPAM 3 1024 13.5 1 16-TCPAM 4 2048 13.5 1 16-TCPAM 5 3072 13.5 1 32-TCPAM 6 5696 13.5 1 32-TCPAM 7 512 13.5 2 16-TCPAM 8 704 13.5 2 16-TCPAM 9 1024 13.5 2 16-TCPAM 10 2048 14.5 2 16-TCPAM 11 3072 14.5 2 32-TCPAM 12 5696 14.5 2 32-TCPAM 13 0 0 1 0 (best effort) 14 0 0 2 0 (best effort) These default entries SHALL be created during agent initialization and MUST not be deleted. Entries following the first 14, can be dynamically created and deleted, to provide custom administrative (configuration) profiles and automatic operating profiles. This table MUST be maintained in a persistent manner.
