LC1J1V1
Output 141
The locked mode composite frame pulse
(LC1J1V1) marks the transport, synchronous
payload envelope and tributary multiframe frame
boundaries on the outgoing stream. LC1J1V1 is
only active in locked mode (OJ1EN register bit
set low). LC1J1V1 is held low in floating mode
(OJ1EN set high).
In outgoing byte interface mode (OBMODE set
high), and locked mode is enabled (OJ1EN set
low), LC1J1V1 pulses high to mark the first C1
byte of the transport envelope frame on the
OD[7:0] bus. It also pulses high to mark the J1
byte(s) which is (are) register selectable to be
implicitly fixed to immediately follow the C1 bytes
or the H3 bytes. Optionally, LC1J1V1 also
marks the third byte after J1 of the first tributary
in each STS-1 (TUG3) stream when the LV1EN
register bit is set high. LC1J1V1 is updated on
the rising edge of SCLK.
In outgoing nibble interface mode (OBMODE set
low), and locked mode is enabled (OJ1EN set
low), LC1J1V1 pulses high to mark the more
significant nibble of the first C1 byte of the
transport envelope frame on the OD[3:0] bus. It
also pulses high to mark the more significant
nibble of the J1 byte(s) which is (are) register
selectable to be implicitly fixed to immediately
follow the C1 bytes or the H3 bytes. Optionally,
LC1J1V1 also marks the more significant nibble
of the third byte after J1 of the first tributary in
each STS-1 (TUG3) stream when the LV1EN
register bit is set high. LC1J1V1 is updated on
the rising edge of NSCLK.
