Function
The transmit section order wire (TSOW) signal
contains the section order wire channel (E1)
inserted into the outgoing stream. The
TTOHEN input takes precedence over TSOW.
TSOW is sampled on the rising edge of
TOWCLK.
The transmit section user channel (TSUC)
signal contains the section user channel (F1)
inserted into the outgoing stream. The
TTOHEN input takes precedence over TSUC.
TSUC is sampled on the rising edge of
TOWCLK.
The transmit line order wire (TLOW) signal
contains the line order wire channel (E2)
inserted into the outgoing stream. The
TTOHEN input takes precedence over TLOW.
TLOW is updated on the rising edge of
TOWCLK.
The transmit line DCC clock (TLDCLK) is a 576
KHz clock used to sample the TLD input.
TLDCLK is generated by gapping a 2.16 MHz
clock.
The transmit line DCC (TLD) signal contains the
line data communications channel (D4 - D12)
inserted into the outgoing stream. The
TTOHEN input takes precedence over TLD.
TLD is sampled on the rising edge of TLDCLK.
