CIRCUIT CC - DCE READY (DATA SET READY)

 CONNECTOR NOTATION: DSR

 DIRECTION: From DCE

This signal indicates the status of the local DCE by reporting to the DTE device

that a communication channel has been established.

CIRCUIT CD - DTE READY (DATA TERMINAL READY)

 CONNECTOR NOTATION: DTR

 DIRECTION: To DCE

This signal controls the switching of the DCE to the communication channel. The

DTE will generate this signal to prepare the DCE to be connected to or removed

from the communication channel.

CIRCUIT CE - RING INDICATOR

 CONNECTOR NOTATION: RING

 DIRECTION: From DCE

This signal indicates that a ringing signal is being received on the

communication channel.

CIRCUIT CF - RECEIVED LINE SIGNAL DETECT (CARRIER DETECT)

 CONNECTOR NOTATION: 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.

CIRCUIT DA - TRANSMIT SIGNAL ELEMENT TIMING (DTE SOURCE)

 CONNECTOR NOTATION: TXCLK (DTE)

 DIRECTION: To DCE

This signal, generated by the DTE, provides the DCE with element timing

information pertaining to the data transmitted by the DTE. The DCE can use this

information for its received data.
