Function
The outgoing tributary synchronous payload
envelope (OTSPE) signal marks the bytes
carrying the tributary synchronous payload
envelope(s). OTSPE is set high to mark each
such byte on the DOUT[7:0] bus. OTSPE,
contains valid data only for bytes in the AU3 or
AU4 virtual container(s), or the STS-1
synchronous payload envelopes. Its contents
should be ignored for bytes in the transport
overhead. OTSPE is updated on the rising edge
of SCLK.
The outgoing tributary V5 byte (OTV5) signal
marks the various tributary V5 bytes. OTV5 is set
high to mark each tributary V5 byte on the
DOUT[7:0] bus. When the output tributary is a
TU3, OTV5 marks the J1 byte of the TU3. OTV5
contains valid data only for bytes in the AU3 or
AU4 virtual container(s), or the STS-1
synchronous payload envelopes. Its contents
should be ignored for bytes in the transport
overhead. OTV5 is updated on the rising edge of
SCLK.
The active low Motorola bus enable (MBEB)
signal configures the TUPP for Motorola bus
mode where the RDB/E signal functions as E,
and the WRB/RWB signal functions as RWB.
When MBEB is high, the TUPP is configured for
Intel bus mode where the RDB/E signal functions
as RDB. The MBEB input has an integral pull up
resistor.
The active low chip select (CSB) signal is low
during TUPP register accesses.
