Re: Frequency Dependent Pilot Sequence support

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:
