Reference: Remote Commands ~ Command Description

:SOURce:DATA:OVERhead:PASSthru:ALL

This command controls the source of transmitted overhead data in Through Mode. The parameter is a numeric value in which each bit enables retransmission of received data for one specific overhead field. The bit values are shown under :SOURCE:DATA:OVERHEAD:PASSTHROUGH. The query form returns the current setting.

Syntax :SOURce<slot>:DATA:OVERhead:PASSthru:ALL? :SOURce<slot>:DATA:OVERhead:PASSthru:ALL <NR1>

:SOURce:DATA:PARIty:LOOP

This command enables the local calculation of B1 and B2 parity bits when the transmitter is in Through Mode. When this function is enabled, the B1 and B2 bits are calculated from the payload value; when it is disabled, the B1 and B2 bits have the values of the received B1 and B2 bits. This setting has no effect when the payload is internally generated. The query form returns the current setting.

Syntax :SOURce<slot>:DATA:PARIty:LOOP? :SOURce<slot>:DATA:PARIty:LOOP <Boolean>

Parameters	Description
THRU	B1 and B2 bit values are taken from the received signal
REGEN	B1 and B2 bit values are regenerated from the transmitted data
FORCE_THRU	B1 and B2 bit values are taken from the received signal, independent of the
	setting of this parameter
FORCE_REGEN	B1 and B2 bit values are regenerated from the transmitted data, independent of
	the setting of this parameter

:SOURce:DATA:PATH:OVERhead:PASSthru

This command controls the source of transmitted path overhead data in Through Mode. The first parameter specifies a path overhead data field; the second selects whether that field's data comes from the received signal (ON) or is generated by the OTS transmitter (OFF). The query form returns the current setting for the specified field.

Syntax :SOURce<slot>:DATA:PATH:OVERhead:PASSthru? <Enum> :SOURce<slot>:DATA:PATH:OVERhead:PASSthru <Enum> ,<Boolean>

Parameters	Description
C2A	C2 (path label) POH byte (bit value 131,072 in…:ALL command)
F2A	F2 POH byte (bit value 524,288)
F3A	F3 (Z3) POH byte (bit value 2,097,152)
G1A	G1 POH byte (bit value 262,144)
H4A	H4 POH byte (bit value 1,048,576)
J1A	J1 (path trace) POH byte (bit value 65,536)
K3A	K3 (Z4) POH byte (bit value 4,194,304)
N1A	N1 POH byte (bit value 8,388,608)
PAYload	Payload data (bit value 16,777,216)
