1. Check if Vectoring is enabled

IOS router shows the training mode as G993.2 even though the line is trained with full vectoring and this documented with the below cosmetic Bug:

Bug Link: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuw72999

Recommended way to check if Vectoring is enabled on a line is using the command below:

CPE# conf t
CPE(config)# service internal
CPE(config)#exit
CPE#test vdsl 0 modem exec adsl info --vectoring
The output of the command is :
adsl: ADSL driver and PHY status
Status: Showtime
Last Retrain Reason: 0
Last initialization procedure status: 0
Max: Upstream rate = 11864 Kbps, Downstream rate = 44782 Kbps
Bearer: 0, Upstream rate = 10456 Kbps, Downstream rate = 41800 Kbps
Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps
Vectoring state: 1
Total error samples Ethernet pkts sent: 0
Total error samples Ethernet pkts discarded: 0
Total error samples statuses sent: 0
Total error samples statuses discarded: 0

Vectoring state: 1 >>>> Vectoring enabled

2. Regarding FDPS (Frequency Dependent Pilot Sequence) differentiates ITU standard G.993.5 733 Modulation of Pilot Sequence:
