Administering Tape Save/Restore Operations

If you do not have a digital tape unit, you should skip this chapter.

The procedures described below assume that your digital tape unit is correctly connected and turned on. See the System 25 Installation and Test Manual for further information. It is also assumed that you will use a high quality audio cassette tape. It is important that you make two backup tapes and that you verify each of those tapes every time you save translations.

Keep the following considerations in mind when performing tape save/restore operations:

Be sure connector “3” is assigned to the “Save Restore Tape” capability (see Administering RS232 Parameters to reassign the connector).

Be sure the tape deck is plugged into connector “3” of the cable.

To save (Action=1), you must press the PLAY and RECORD buttons.

To verify (Action=2) and restore (Action=3), you must press the PLAY button,

Caution Action=3 will interrupt phone service for about five minutes.

Save/Restore

It is most unlikely that your System 25 would encounter a major catastrophe in which all your translations were lost. However, if such an event were to occur, a backup tape would allow you to restore system translations (the most current you have saved) in about five minutes. It takes only a few minutes to make a backup tape. It’s important that you keep at least three tapes of past translations, updating the two oldest tapes during system save procedures. This way, if something goes wrong during a save procedure and both tapes of the current system translations are damaged, you’ll still have a previous version on tape to use as a backup.

Verify

You should always verify a completed tape save operation. Successful completion of the Verify command assures you that what you have saved on tape matches exactly the translations in your system.

Using the Digital Tape Unit
