The outgoing tributary V5 byte #1 (OTV5[1])
signal marks the tributary V5 bytes of the STM-4
or STM-1 #1 stream.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), OTV5[1] is set high to
mark each tributary V5 byte of the STM-1 #1
stream on the OD[7:0] bus. When the outgoing
tributary is a TU3, OTV5[1] marks the J1 byte of
the TU3. OTV5[1] is updated on the rising edge
of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), OTV5[1] is set high to
mark each tributary V5 byte of the STM-4
stream on the OD[7:0] bus. When the outgoing
tributary is a TU3, OTV5[1] marks the J1 byte of
the TU3. OTV5[1] is updated on the rising edge
of HSCLK.
OTV5[2]
Output K20
The outgoing tributary V5 byte #2 (OTV5[2])
signal marks the tributary V5 bytes of the STM-1
#2 stream.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), OTV5[2] is set high to
mark each tributary V5 byte on the OD[15:8]
bus. When the outgoing tributary is a TU3,
OTV5[2] marks the J1 byte of the TU3. OTV5[2]
is updated on the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
