Using the Diagnostic Control Panel (DCP)

The DCP’s liquid crystal display (LCD) consists of two 16-character lines which display modem status, control
functions, and configuration options as well as indicating your location in the Top-Level menu tree.

To change a factory template from the Sync Leased preset configuration using the DCP, perform the following
steps:

1. Press the function key below Configure to select the Configure branch.

The LCD now displays Ld EditArea frm.

2. Press the  

  key until Factory comes into view, then press the F1 key to display the factory preset

configurations.

Factory preset configurations are Sync Leased, Async Leased, TMp (Trellis Multipoint), Async Dial,
Sync Dial, and UNIX Dial. If Sync Leased or Async Leased is selected, you must choose either Answer
or Originate mode. If TMp is selected, you must choose either Control or Trib (Tributary) mode.

3. Press the  

  key until the appropriate factory preset appears on the LCD, and press the corresponding

function key to select your choice. (For certain factory presets you will also need to choose the
appropriate mode.)

4. Choose Function appears and displays the Edit and Save functions.

5. Press the F3 key (Save) to save the new factory preset configuration to one of three configuration areas,

Active (Saved), Customer 1, or Customer 2.

(These three configuration areas are nonvolatile memory locations. Active (Saved) contains the most
recently saved changes to any configuration options. In the event of power loss, the modem retrieves these
configuration options. Customer 1 and Customer 2 are user-defined configuration areas.)

The LCD now displays Sav EditArea to.

6. Press the  

  key until the appropriate configuration area appears on the LCD, then press the

corresponding function key to select your choice. (Saving configuration options to the Active (Saved)
configuration area automatically saves them to the Active (Operating) configuration area.) The LCD
displays Command Complete.

7. The modem is now configured with the selected factory template. Press the  

  key to return to the

Top-Level menu.

Refer to Chapter 5, Configure Branch, in Document No. 3920-A2-GH30for more information regarding default
factory configuration options.
