Client Signal
Multiplexing 1
Multiplexing 2
See a description of the setting options in the Mapping Dialog section below.
FEC Control
Use the drop-down menu to select whether or not to transmit FEC (Forward
Error Correction) data.
No FEC: OTUk data is transmitted without FEC encoding.
RS(255,239): OTUk data is transmitted with FEC encoding. RS(255,239)
code is defined in ITU-T Rec. G.709.
TTI Encoding
Use the drop-down menu to select TTI encoding method.
ITU-T: Corresponding to ITU-T Rec. G.709.
ANSI: All TTI 64 bytes can be edited as the operator specification.
OH
Touch an OH button to launch the corresponding Overhead dialog box.
Depending on whether you have selected multiplexing or not in the frame
mapping, there will be one or more overheads to configure.
The dialog box is described in detail in the Overhead Dialog section below.
Dummy CH
Only displayed when the frame mapping is set to multiplexing. Select the
payload of the dummy channel from the drop-down menu.
Copy: Transmit the copy of the main Tributary Port (TP) data to the
dummy Tributary Port (TP).
Unused: Dummy ODUj data which are generated separately from the
Main ODUj data are embedded into the remained TPs.
TP
Only displayed when the frame mapping is set to multiplexing. Touch the TP
button and use the launched dialog box to set the number of TP or TS. The
selected TP number is showed on the button.
The dialog box is described in the TP/TS section.
GFP-F
Only displayed when the client signal is Ethernet. Touch the GFP-F button to
launch a dialog box where you can to select parameters.
The dialog box is described in the GFP-F section.
GFP-T
Only displayed when the client signal is GbE. Touch the GFP-T button to
launch a dialog box where you can to select CSF Replacement.
The dialog box is described in the GFP-T section.
Configure
Only displayed when the client signal is PRBS. Touch the Configure button
to launch a dialog box where you can select pattern type.
PRBS9 to PRBS31: Pseudo-random bit sequence. The number indicates
the bit length of sequence.
For example, bit length of PRBS9 is 2
9
-1=511.
PRBS Pattern Inversion is enabled.
User [32] bit, User [2048] bit: 32 bits or 2048 bits length pattern.
The field which shows bit length is enabled. Touch the field to launch the
dialog box to define the bit pattern. Refer to The User Pattern Editor.
