Signal
Mnemonic
TxD_B Transmit Data (B). Data to be transmitted; output from
DTE to DCE.
TxC_A Transmit Signal Element Timing—DCE (A). Control
signal that clocks input data.
RxD_B Receive Data (B). Data which is demodulated from the
receive line; input from DCE to DTE.
RxC_A Receive Signal Element Timing—DCE (A). Control
signal that clocks input data.
RTS_B Request to Send (B). Output from DTE to DCE when
required to transmit a message.
LL_A Local Loopback (A). Reroutes signal within local DCE.
In DTE configuration, always tied inactive and driven
false. In DCE configuration, ignored
DTR_A Data Terminal Ready (A). Output from DTE to DCE
indicating that the DTE is ready to send or receive data.
RL_A Remote Loopback (A). Reroutes signal within remote
DCE. In DTE configuration, always tied inactive and
driven false. In DCE configuration, ignored.
DSR_B 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.
DTR_B Data Terminal Ready (B). Output from DTE to DCE
indicating that the DTE is ready to send or receive data.
TxCO_A Transmit Signal Element Timing—DTE (A). Control
signal that clocks output data.
TM_A Test Mode (A). Indicates whether the local DCE is
under test. In DTE configuration, ignored. In DCE
configuration, always tied inactive and driven false.
