Out-Of-Service

Signaling (for FCD-IPM with a

sublink)MARK

Determines the value of the A, B signaling bits sent to Link 1 when the sublink is in the Out-Of-Service state. The C and D signaling bits are not affected.

Both A and B signaling bits are forced to '1' during out-of-service period

	SPACE	Both A and B signaling bits are forced to '0' during out-of-service
		period
	MARK-SPACE	The A and B signaling bits are forced to '1' for 2.5 seconds, then
		shift to the '0' state until the out-of-service period ends
	SPACE-MARK	The A and B signaling bits are forced to '0' for 2.5 seconds, then
		shift to the '1' state until the out-of-service period ends.
Sublink Status	Enable or Disable
