Function: Sets the DTE loopback mode over normal full-duplex operation. DTE loopback
is a diagnostic test that causes the DTE to transmit a signal to the DCE. The
DTE then waits for the DCE to return the signal. The DCE provides the transmit
and receive clock signals.
Instructions: Click on Values and select one of the following DTE loopback settings:
• No_Loopback -- Prevents the DTE from sending loopback signals to the DCE.
• Local_Digital (Loop A) -- Allows the DTE to check the DTE/DCE interface. In a Loop
A test, the DTE transmission is returned to the DTE on the received local DCE data
circuit. The CA LED (DCE Ready) must be on.
• Local_Line (Loop B) -- Allows the DTE to check the DTE/DCE interface and the
transmit and receive sections of the local DCE. In a Loop B test, the output of the
transmit section of the DCE is returned to the receive section of the DCE. The CA
LED (DCE Ready) must be on.
• Remote_Line (Loop C) -- Allows the DTE to check the functions of the transmission
path to the remote DCE interface.
