12

TxC_B

Transmit Signal Element Timing—DCE (B).

Control signal that clocks

 

 

input data.

 

 

 

 

13

CTS_B

Clear to Send (B). Input to DTE from DCE to indicate that message

 

 

transmission can begin.

 

 

 

 

14

TxD_B

Transmit Data (B). Data to be transmitted; output from DTE to DCE.

 

 

 

 

15

TxC_A

Transmit Signal Element Timing—DCE (A).

Control signal that clocks

 

 

input data.

 

 

 

 

16

RxD_B

Receive Data (B). Data which is demodulated from the receive line; input

 

 

from DCE to DTE.

 

 

 

 

 

17

RxC_A

Receive Signal Element Timing—DCE (A).

Control signal that clocks input

 

 

data.

 

 

 

 

18

RTS_B

Request to Send (B). Output from DTE to DCE when required to transmit a

 

 

message.

 

 

 

 

19

LL_A

Local Loopback (A). Reroutes signal within local DCE. In DTE

 

 

configuration, always tied inactive and driven false. In DCE configuration,

 

 

ignored

 

 

 

 

20

DTR_A

Data Terminal Ready (A). Output from DTE to DCE indicating that the

 

 

DTE is ready to send or receive data.

 

 

 

 

21

RL_A

Remote Loopback (A). Reroutes signal within remote DCE. In DTE

 

 

configuration, always tied inactive and driven false. In DCE configuration,

 

 

ignored.

 

 

 

 

22

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.

 

 

 

23

DTR_B

Data Terminal Ready (B). Output from DTE to DCE indicating that the DTE

 

 

is ready to send or receive data.

 

 

 

 

 

24

TxCO_A

Transmit Signal Element Timing—DTE (A).

Control signal that clocks

 

 

output data.

 

 

 

 

25

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.
