Signal Name and Description
Transmit Signal Element Timing—DCE (B). Control signal that clocks
input data.
Clear to Send (B). Input to DTE from DCE to indicate that message
transmission can begin.
Transmit Data (B). Data to be transmitted; output from DTE to DCE.
Transmit Signal Element Timing—DCE (A). Control signal that clocks
input data.
Receive Data (B). Data which is demodulated from the receive line; input
from DCE to DTE.
Receive Signal Element Timing—DCE (A). Control signal that clocks input
data.
Request to Send (B). Output from DTE to DCE when required to transmit a
message.
Local Loopback (A). Reroutes signal within local DCE. In DTE
configuration, always tied inactive and driven false. In DCE configuration,
ignored
Data Terminal Ready (A). Output from DTE to DCE indicating that the
DTE is ready to send or receive data.
Remote Loopback (A). Reroutes signal within remote DCE. In DTE
configuration, always tied inactive and driven false. In DCE configuration,
ignored.
Data Set Ready (B). Input to DTE from DCE to indicate that the DCE is
ready to send or receive data. In DCE configuration, always true.
Data Terminal Ready (B). Output from DTE to DCE indicating that the DTE
is ready to send or receive data.
Transmit Signal Element Timing—DTE (A). Control signal that clocks
output data.
Test Mode (A). Indicates whether the local DCE is under test. In DTE
configuration, ignored. In DCE configuration, always tied inactive and driven
false.
