Output T22
The tributary idle indication signal output #3
(IDLE[3]) marks tributaries on the outgoing STM-
1 #3 stream that are in idle state.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), IDLE[3] is set high
when idle code is inserted in the associated
tributary on the OD[23:16] and is set low when
the idle code is not inserted. IDLE[3] is updated
on the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), IDLE[3] is invalid.
