According to USR/Rockwell: As far as T1 lines are concerned, both Rockwell and USR claim to have been able to avoid signal loss in T1 lines by detecting what they call "digital-padding" in T1 switch. This digital pad can cause the modem signal to drop as much as 6db. Once they detect this digital pad during the first stage of negotiation, they boost their transmit level by 6db. They also have algorithm to compensate for robbed-bit signaling.
