Digital Data Input from Terminal Equipment
The exact role that this input pin plays, depends upon whether
the XRT4500 is operating in the DTE or DCE Mode.
DTE Mode:
SCTE (Transmit Clock Echo) Input
The Serial Communications Controller (at the DTE Terminal) is
expected to derive the SCTE (Transmit Clock Echo) clock signal,
from the TXC signal, and input it (into the XRT4500) via this
input pin. The XRT4500 will convert this binary data stream into
either the V.35, V.11 or V.28 format and will output this data via
the TX2A and TX2B output pins.
DCE Mode:
RXC (Receive Clock) Input
The Serial Communications Controller (at the DCE Terminal) is
expected to apply the RXC clock signal to this input pin. The
XRT4500 will convert this binary data stream into either the V.35,
V.11 or V.28 format and will output this data via the TX2A and
TX2B output pins.
Note:
If the XRT4500 has been configured to operate in both the
DTE and the “Echoed Clock” Mode, then the XRT4500 will
ignore this input pin and will instead use the clock signal which is
output via the “D_TXC” output pin (e.g., RX3D or pin 73).

Transmitter 3 – Digital Data Input from Terminal Equipment
The exact role that this pin plays depends upon whether the
XRT4500 is operating in the DCE or DTE Modes.
DTE Mode:
This input pin is not used
DCE Mode: TXC – Transmit Clock Signal
This input pin functions as the “TXC” (Transmit Clock) input signal
from the DCE Terminal. The XRT4500 will convert this “digital”
clock data into either the V.35, V.11 or V.28 format and will output
this data via the TR3A and TR3B output pins.
