Function
192 kHz clock 50 % duty cycle. When line DCC is selected,
RSLDCLK1-4 is a nominal 576 kHz clock with 50 % duty
cycle.
RSLD1-4 is updated on the falling edge of RSLDCLK1-4 and
ROHFP1-4 is used to identify the MSB of the D1 or the D4
byte on RSLD1-4.
The RRMP register contains the RSLD_SEL register bit used
to select the section or line DCC and the RSLD_TS register bit
that can be used to tri-state RSLDCLK1-4 and RSLD1-4
outputs.

The
receive section or line data communication channel
(RSLD1-4) signal contains the received section DCC (D1-D3)
or line DCC (D4-D12).
In STS-192/STM-64 mode, only RSLD1 is active. RSLD2-4 is
undefined.
RSLD1-4 is updated on the falling edge of RSLDCLK1-4 and
should be sampled externally on the rising edge of
RSLDCLK1-4. ROHFP1-4 is used to identify the MSB of the
D1 or the D4 byte on RSLD1-4.
The RRMP register contains the RSLD_SEL register bit used
to select the section or line DCC and the RSLD_TS register bit
that can be used to tri-state RSLDCLK1-4 and RSLD1-4
outputs.
