Digi 90031300 Configuration modification, User selects short-haul for the span-type by entering

Configuration modification

For each parameter, the currently active value will be shown in square brackets.

Each modifiable parameter has a “selector” number associated with it and displayed on the left margin. For example, the parameter “Span Type” has the selector value 5. From this T1 configuration display, the user can modify any of the displayed parameters by typing in its associated number at the prompt. The user will then be prompted to input a new value for the parameter.

If the parameter is one for which there is a specific enumerated set of values, each possible value will be shown along with a selector number unique to it. The user then selects the value by typing in the selector number and pressing the <Enter> key. Continuing on with the “Span type” parameter as an example, there will be two possible values: long-haul or short-haul. The selector number for long-haul is 1 and the selector number for short-haul is 2.

On the other hand, if the parameter is one with a broad range of possible values, such as line length, then the user is simply asked to enter the new value and finish the selection by pressing the <Enter> key.

When a user modifies a parameter, the change doesn’t take effect until the user enters the command letter “S” to store the new configuration. When any parameter has a value that has been changed from the currently active value, the new but not yet active value will be shown in angle brackets < >. After the new configuration has been stored and made active, this new value will be displayed surrounded by square brackets [ ] and the old and no longer active value will not have any brackets displayed around it.

The user can cancel a change to a parameter by simply pressing the <Enter> key without making a selection and the parameter’s value will remain unchanged.

Here is an example which shows how to change the above configuration from long-haul to short haul:

( user chooses to change the span-type by entering “5” )

: 5

The current value for Span Type is Long The possible values are:

1)Long

2)Short

Hit return to keep the selection unchanged, or select a number to choose the new value

( user selects short-haul for the span-type by entering “2” )

: 2

The current value for Span Type has been changed to Short As a consequence of this change, The Line Build-out and Receiver Gain Limit parameters have become disabled.

The Line Length Parameter has become enabled. You need to verify its value.
