CIRCUIT DB - TRANSMIT ELEMENT TIMING (TxClk - DCE Source)
CONNECTOR NOTATION: +RTCLK,-RTCLK
DIRECTION: From DCE
This signal, generated by the DCE, provides the DTE with element
timing information pertaining to the data transmitted to the DCE.
CIRCUIT DD - RECEIVER ELEMENT TIMING (RxClk - DCE Source)
CONNECTOR NOTATION: +RRCLK,-RRCLK
DIRECTION: From DCE
This signal, generated by the DCE, provides the DTE with element
timing information pertaining to the data transmitted by the DCE.
CIRCUIT CA - REQUEST TO SEND (RTS)
CONNECTOR NOTATION: +RTS,-RTS
DIRECTION: To DCE
This signal controls the data channel transmit function of the local
DCE and, on a half-duplex channel, the direction of the data
transmission of the local DCE.
CIRCUIT CB - CLEAR TO SEND (CTS)
CONNECTOR NOTATION: +CTS,-CTS
DIRECTION: From DCE
This signal indicates to the DTE whether the DCE is conditioned to
transmit data on the communication channel.
CIRCUIT CF - CARRIER DETECT (CD)
CONNECTOR NOTATION: +CD,-CD
DIRECTION: From DCE
This signal indicates to the DTE whether the DCE is conditioned to
receive data from the communication channel, but does not
indicate the relative quality of the data signals being received.
