Yellow alarm transcoding to NET should be enabled any time the EQP
and network framing are not the same and transcoding is desired.

This option has a default of

These two options control whether the equipment (EQP) side is encoding
the signal toward the EQP and decoding the signal received from the EQP
for B8ZS.

If AMI (Alternate Mark Inversion) line coding is required, select

is the default setting.

This option determines whether the CRC is regenerated toward the
equipment (EQP) from the NET.

Refer to the CAUTION under the
