Port Test Menu Items for 0.1 Nx56/64
0.1Nx56/64 is the base Nx interface. It offers the following test functions:
DTE LOOPBK
This initiates a loopback. The following options are available:
PRT/LCL 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 V.54 code to be sent to the far end. The Nx at the far end activates a PORT/LCL loopback upon detection of the V.54 code.
OFF | The loop is deactivated. |
The TSU 120 checks the remote loopback activation by detecting a proper response from the remote end. While waiting for the re- sponse, the display shows Looping. If successful, the display changes to
511 PATTERN
This activates the generation of the 511 test pattern. The follow- ing options are available:
ON | The pattern check circuitry is enabled and a |
| test started. The test is ended by selecting |
| OFF. |
OFF | The pattern generation and check is |
| disabled. |
511 RESULTS |
|
This displays the results of the 511 test indicated in the 511 option. The results are in the form of the number of errored sec- onds. The error count can be cleared by pressing Clear (Shift+9).
