ANT-20SE
Through Mode
The received signal is looped through the ANT-20SE and re-transmitted by the generator.
One tributary signal can be output (dropped).
The ANT-20SE can also operate in Through Mode as a signal monitor without affecting the
signal content.

In conjunction with the options "PDH MUX/DEMUX" and "M13 MUX/DEMUX", BN 3035/90.30
to BN 3035/90.32, the ANT-20SE provides access to the tributary channels within the MUX/
DEMUX chain. This also applies if the PDH signal is transmitted in a container.
The looped-through signal can also be jittered using the Jitter Generator options (Jitter
Generator up to 155 or 622 Mbit/s, BN 3035/90.60 to 61). This function is available for all bit
rates fitted to the instrument.
