OTS9100 User Manual 3-57
:SOURce:DATA:SPE:STUFfing
This command controls the SPE fixed byte stuffing. When enabled, columns 30 and 59 of the active
STS-1 channel contain the fixed byte value zero and are not used for payload. When disabled, columns
30 and 59 are part of the payload. This command is applicable when the active channel structure is set
to STS-1. The query form returns the current setting.
Syntax :SOURce<slot>:DATA:SPE:STUFfing?
:SOURce<slot>:DATA:SPE:STUFfing <Boolean>
:SOURce:DATA:STRUcture
This command sets the structure of the signal generated by the OTS-9000 transmitter. The query form
returns the current setting.

:SOURce<slot>:DATA:STRUcture <Enum>
Parameter Description
G10C Bulk data at 10Gb/s
G2P5C Bulk data at 2.5 Gb/s
M622C Bulk data at 622 Mb/s
M155C Bulk data at 155 Mb/s
M51A Bulk data at 51 Mb/s (SONET only)
:SOURce:DATA:TOH:STS1A:ALL
This command sets the values of all bytes in the generated STS-1 #1 Transport Overhead data. The
query form returns the current setting. There are 27 bytes in the data block. These correspond to the
overhead bytes A1, A2, J0, B1, E1*, F1*, D1*, D2*, D3*, H1..H3, B2, K1*, K2*, D4*..D12*, S1*, Z2*, E2*.
Only those bytes marked with * are settable; the values of the other bytes are automatically set by the
transmitter.

:SOURce:DATA:TOH:STS1A:BYTE
This command sets the value of a specific byte in the generated STS-1 #1 Transport Overhead data. The
byte selection is specified by three numeric parameters, for STS-1 number, row, and column; because
only STS-1 #1 may be selected, the first parameter must be set to 1. The query form returns the current
byte value.
