American Telecom AM64/128A Injecting 0s, Injecting 1s, Injection Mode, Transparent Mode, Time

Test Menu	AM64/128A User Manual

2/ Pattern display

The pattern display usually shows	Injecting 0s

Pressing SELECT will cause binary 1s to be injected (e.g. for loop verification):

Injecting 1s

This pattern will continue to be injected until the SELECT key is pressed again, (or the mode is exited).

3/ Transparency display

The Transparency option is usually disabled, when the display reads:

Injection Mode

Pressing SELECT on this option changes the display to:

Transparent Mode

Binary 0 injection is then disabled and the data path is direct to the DTE or data tester. Selecting Transparent mode changes the pattern display to show:

No Injection

The facility to inject binary 1's remains however. The SELECT key now toggles between no pattern injected and injecting binary 1's.

4/ Time display

The time display simply shows the time since the test has started in seconds.

For example

Time 000010

If the count is stopped the display is	T Stop 000010

Using the transparent mode of the Data Test to test the local interface cable (alternatively a local loop can be used with the local DTE)
