66 The receive section DCC (RSD) signal contains
the section data communications channel (D1,
D2, D3) extracted from the incoming stream.
RSD is updated on the falling edge of
RSDCLK.
70 The receive order wire clock (ROWCLK) is a 64
kHz clock used to update the RSOW, RSUC,
and RLOW outputs. ROWCLK is generated by
gapping a 72 kHz clock.
68 The receive section order wire (RSOW) signal
contains the section order wire channel (E1)
extracted from the incoming stream. RSOW is
updated on the falling edge of ROWCLK.
69 The receive section user channel (RSUC)
signal contains the section user channel (F1)
extracted from the incoming stream. RSUC is
updated on the falling edge of ROWCLK.
81 The receive line order wire (RLOW) signal
contains the line order wire channel (E2)
extracted from the incoming stream. RLOW is
updated on the falling edge of ROWCLK.
80 The receive line DCC clock (RLDCLK) is a 576
kHz clock used to update the RLD output.
RLDCLK is generated by gapping a 2.16 MHz
clock.
79 The receive line DCC (RLD) signal contains the
line data communications channel (D4 - D12)
extracted from the incoming stream. RLD is
updated on the falling edge of RLDCLK.
83 The receive automatic protection switch
channel clock (RAPSCLK) is a 128 kHz clock
used to update the RAPS output. RAPSCLK is
generated by gapping a 144 kHz clock.
