No.
Function
Output H3
The tributary idle indication signal output #1
(IDLE[1]) marks tributaries on the outgoing STM-
4 or STM-1 #1 stream that are in idle state.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), IDLE[1] is set high
when idle code is inserted in the associated
tributary of the STM-1 #1 stream on the OD[7:0]
and is set low when the idle code is not inserted.
IDLE[1] is updated on the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), IDLE[1] is set high when
idle code is inserted in the associated tributary
of the STM-4 stream on the OD[7:0] and is set
low when the idle code is not inserted. IDLE[1] is
updated on the rising edge of HSCLK.
IDLE[2]
Output K22
The tributary idle indication signal output #2
(IDLE[2]) marks tributaries on the outgoing STM-
1 #2 stream that are in idle state.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), IDLE[2] is set high
when idle code is inserted in the associated
tributary on the OD[15:8] and is set low when
the idle code is not inserted. IDLE[2] is updated
on the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), IDLE[2] is invalid.
