DIS/DTC
Identification Signal Format
A fixed pattern is transmitted to the receiving side at a speed
(2400 to 9600 bps) designated by DCS, and the receiving side
optimizes the automatic equalizer, etc., according to this signal.
Sends 0 continuously for 1.5 seconds at the same speed as the
training signal.
Notifies the sending side that TCF has been properly received.
X0100001
If TCF is not properly received, FTT (Failure To Train)
X0100010 is relayed to the sender. The sender then reduces
the transmission speed by one stage and initiates training once
again.
Used for reconfirming the receiving side like training 1.
