7.2 HDB3/B3ZS/AMI Non-LIU Line Interface Mode

The Non-LIU Line Interface Mode disables the LIU and a digital representation of AMI is output/input on the

TPOSn/TNEGn signals and the RPOSn/RNEGn signals. Selection between AMI and HDB3/B3ZS is made via the

LINE.TCR Register. HDB3 and B3ZS selection is controlled by the configuration selected by the FM bits. The DS3

modes select the B3ZS line code while the E3 modes select the HDB3 line code.
