Port Test Menu Items for 0.1 Nx56/ 64

0.1Nx56/64 is the base Nx interface. It offers the following test functions:

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 PRT/LCL
	loopback upon detection of the V.54 code.
OFF	The loop is deactivated.

The ESU 120e 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 Looped -Up. If unsuccessful, the display shows Failed.

511 PATT

Activates the generation of the 511 test pattern.

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.

D IS 511 RESLT

Displays the results of the 511 test indicated in the 511 option. The results are in the form of the number of errored seconds. The error count can be cleared by pressing the Clear key (shift+9).
