149.4.2.4.5 PHY Capability Bits

 

The format of PHY capability bits is Oct10<0> = OAMen, Oct10<2:1> = InterleaverDepth, Oct10<4:3> = PrecodeSel, Oct10<5> = SlowWakeRequest, Oct10<6> = EEEen and Oct10<7> = VendorSpecificMessage. EEEen and OAMen indicate EEE and MultiGBASE-T1 OAM capability enable, respectively. The PHY shall indicate the sup-port of these two optional capabilities by setting the corresponding capability bits. When the VendorSpecificMessage bit is set to 1 then the remaining 23 bits of the MSG24 field is vendor specific data. Otherwise when VendorSpecificMessage=0, the remaining bits shall be reserved and set to 0.

 

Table 149–12a—PHY Capability Bits when VendorSpecificMessage=0

 

octet 8								octet 9								octet 10
0	1	2	3	4	5	6	7	0	1	2	3	4	5	6	7	0	1	2	3	4	5	6	7
Reserved																OAMen	InterleaveDepth		PrecodeSel		SlowWakeRequest	EEEen	VendorSpecificMessage = 0

 

Table 149–12b—PHY Capability Bits when VendorSpecificMessage=1

 

octet 8								octet 9								octet 10
0	1	2	3	4	5	6	7	0	1	2	3	4	5	6	7	0	1	2	3	4	5	6	7
