12 DEFINITION OF INTERFACE SIGNALS
CIRCUIT AB - SIGNAL GROUND
CONNECTOR NOTATION: DGND
DIRECTION: Not applicable
This conductor directly connects the DTE circuit ground to the DCE circuit ground.
CIRCUIT CC - DATA SET READY (DSR)
CONNECTOR NOTATION: +DSR,-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 BA - TRANSMITTED DATA (TxD)
CONNECTOR NOTATION: +TXD,-TXD
DIRECTION: To DCE
This signal transfers the data generated by the DTE through the communication channel to one or more remote DCE data stations.
CIRCUIT BB - RECEIVED DATA (RxD)
CONNECTOR NOTATION: +RXD,-RXD
DIRECTION: From DCE
This signal transfers the data generated by the DCE through the communications channel to one or more remote DTE data stations.
CIRCUIT DA - TRANSMIT ELEMENT TIMING (TxcLK- DTE Source)
CONNECTOR NOTATION: +TTCLK,-TTCLK
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.
