Port Test Menu Items Nx/DBU (0.1)

Nx/DBU (0.1) is the base Nx interface. It offers the following

test functions:

DTE LOOPBACK

This initiates a loopback. The following options are available:

PORT/LOCAL

The Nx port activates both a Local loopback (back toward the

DTE) and a Port loopback when either is invoked.

REMOTE

The remote loopback causes a channelized V.54 code to be

sent to the far end. The Nx at the far end activates a PORT/

LOCAL loopback upon detection of the V.54 code.

OFF

The loop is deactivated.

REM V.54 Cont.

The remote loopback causes a continuous V.54 code to be sent

to the far end. The Nx at the far end activates a PORT/

LOCAL loopback upon detection of the V.54 code.

The execution of Port Tests will disrupt normal data flow in the

port tested.

The TDU 120e checks the remote loopback activation by detecting

a proper response from the remote end. While waiting for the re-

sponse, the display shows

OOPING

. If successful, the display

changes to

OOPED

-U

. If unsuccessful, the display shows

AILED
