Paragon-neo: What line coding does Paragon-neo use for T1 and E1 frequency measurements ?

Paragon-neo E1 and T1 frequency measurements are made using the RJ48 or BNC clock measurement ports:

Open

E1 signals using either AMI or HDB3 line coding can be measured.

T1 signals using either AMI or B8ZS line coding can be measured.

Paragon-neo is agnostic to the line coding, it extracts a clock frequency from the incoming T1 / E1 signal that is measured. There is no configuration necessary in the GUI.
