OTN Multiplexing
As OTN moving forward from a point to point technology to a
network technology additional features getting implemented.
In special OTN-Multiplexing is to mention as such a feature. The
ONT-503/-506/-512 will support ODU2/1 multiplexing in ODU3.
Software option 43G OTN Mulitplexing BN 3061/93.14

User Background Structured ODU1/ODU2
With user defined PM-TTI and a NULL client payload
Generation enable/disable
Background The remaining time slots are filled ODU1/ODU2
With a user defined PM-TTI, identical all channels
and a NULL client payload
User background and background
can be overwritten by ODU-OCI, ODU-AIS, and ODU-LCK
Only one multiplex type is supported at a time ODU1 or ODU2. TX
and RX not coupled.
Time slot allocation Foreground and user background can be
Free allocated, background channels
Are automatically allocated.
Client offset stuffing
Following modes a supported Negative, positive,
Double positive
Foreground Default 0 ppm to client bit rate
Offset range ± 65 ppm
User Background Enabled, default 0 ppm to client bit rate
Offset range ± 65 ppm
Background No stuffing support
Other generator capabilities are identical to OTU3 for the Fore-
ground with following restrictions:
No SM support, because only on OTU available.
No FEC support, because only on OTU available.

seconds
Other analyzer capabilities are identical to OTU3 for the foreground
with following restrictions:
No SM support, because only at OTU layer available
No FEC support, because only at OTU layer available
No GCC capture
