7.4.1.1 Tx Setup > Hierarchy > Through Mode
Tapping the Hierarchy box opens the Tx Hierarchy Setup screen.
1) Normal Mode: Unit working as normal SONET mode.
2) Transparent Through mode
All the traffic goes through the unit untouched and the unit can monitor it. It is comparable to Monitor mode with a 10/90 splitter.
In transparent mode, the unit regenerates the signal in amplitude. The clock is recovered from the received signal.
3) Payload Through mode:
Overhead overwrite Editing Thru mode (OH and Payload overwrite)
Regardless of the payload selection, all data in the payload space goes through, the Section overhead bytes can be manipulated.
Errors and alarms can be inserted into the overhead. Used to test network behavior under certain conditions, such as alarms and
APS. To select payload through, the payload has to be the same for the relevant ports.
7.4.2 Tx Setup > Interface
Tapping the Tx Interface box opens the Tx Interface Setup screen. In this screen both electrical and optical options can be
selected.
