CIRCUIT DB - TRANSMIT SIGNAL ELEMENT TIMING (DCE SOURCE)

 CONNECTOR NOTATION:TXCLK (DCE)

 DIRECTION: From DCE

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

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

information for its received data.

CIRCUIT DD - RECEIVER SIGNAL ELEMENT TIMING (DCE SOURCE)

 CONNECTOR NOTATION: RXCLK (DCE)

 DIRECTION: From DCE

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

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

information for its received data.

CIRCUIT LL - LOCAL LOOPBACK

 CONNECTOR NOTATION: LLBK

 DIRECTION: To DCE

This signal provides a means whereby a DTE may check the functioning of the

DTE/DCE interface and the transmit and receive sections of the local DCE.

CIRCUIT RL - REMOTE LOOPBACK

 CONNECTOR NOTATION: RLBK

 DIRECTION: To DCE

This signal provides a means whereby a DTE or a facility test center may check

the transmission path up to and through the remote DCE to the DTE interface

and the similar return transmission path.

CIRCUIT TM - TEST MODE

 CONNECTOR NOTATION: TEST MODE

 DIRECTION: From DCE

This signal indicates to the DTE that the DCE is in a test condition. The DCE

generates this signal when it has received a local loopback or remote loopback

signal from the DTE.
