The outgoing tributary payload active #1
(OTPL[1]) signal marks the bytes carrying the
tributary payload for the STM-4 or STM-1 #1
stream.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), OTPL[1] is set high to
mark each tributary payload byte of the STM-1
#1 stream on the OD[7:0] bus. OTPL[1] is
updated on the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), OTPL[1] is set high to
mark each tributary payload byte of the STM-4
stream on the OD[7:0] bus. OTPL[1] is updated
on the rising edge of HSCLK.
OTPL[2]
Output J23
The outgoing tributary payload active #2
(OTPL[2]) signal marks the bytes carrying the
tributary payload for the STM-1 #2 stream.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), OTPL[2] is set high to
mark each tributary payload byte on the
OD[15:8] bus. OTPL[2] is updated on the rising
