MUX/DEMUX Function (Option)
When the MUX/DEMUX option is added, the multiplexing
structure including the frame alignment signal can be
generated, and multiplexer/demultiplexer measurement can be
performed.

Through Modes
One of the three through modes can be selected: (1)
Transparent,
(2) Overhead/Overwrite, and (3) Payload/Overwrite.
The external DS1/DS3/PDH signal can be added/dropped
● Transparent
For in-service monitoring

Non Frame Pattern/CID Pattern
Frames can be set on/off at all bit rates. CID pattern can
generate or analysis at SDH/SONET measurement.
