Administering Tape Save/Restore Operations
NOTE: 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 R3 Installation and Maintenance 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 these tapes each time you save translations.
Caution: You should...

Using the Digital Tape Unit
To insert the cassette and
rewind the tape:1     Press the STOP/EJECT button on the tape unit. (The
plastic cover over the cassette well pops up.)
2     Insert the cassette into the cassette well (Side A up) so that
the exposed tape faces the tape unit’s buttons. Press the
cassette down until it snaps into place.
3     Close the plastic cover.
4     Press the REWIND button, and wait for the tape unit to
completely rewind tape.
NOTE: Do this before beginning any save, verify,...

To troubleshoot:6     Type C. The line now reads:
Save/Restore: Action = 1 Data = 1
The tape unit automatically starts the Save procedure.
Caution: System 25 does not know whether your tape unit
is actually running at this point. For example, if you
forgot to press the RECORD button along with the PLAY
button, the system cannot tell you that. You might only
discover this problem by using the Verify function.
When the Save is complete, the tape unit stops.
If the Save is successful, the SAT displays:
SAVE...

To Verify:1     From the Main Menu prompt, enter 9 to select
Save/Restore.
2     At Action =, enter 2. You see:
Save/Restore: Action = 2 Data =
3     Type d and at Data =, enter 1.
You see this warning message:
W25: YOU ARE ABOUT TO START A TAPE VERIFY
C for continue, any other key to abort
4     Type C. The entire line now reads:
Save/Restore: Action = 2 Data = 1
The tape unit automatically starts the Verify procedure.
The tape unit stops when the verification is complete. If
the verification is...

Restore the System Translations from a Backup Tape
NOTE: This procedure will interrupt your phone service for about ten minutes. Any calls in
progress will be dropped!
To begin:
To Restore:1     Insert cassette and rewind the tape (as required).
2     Press the PLAY button on the tape unit. (The tape unit
does not begin to operate yet.)
1     From the Main Menu prompt, enter 9 to select
Save/Restore.
2     At Action =, enter 3. You see:
Save/Restore: Action = 3 Data =
3     Type d and at Data =, enter 1....

To troubleshoot:1     Rewind the tape and perform the restoration procedure
again. If the restoration fails a second time, get a blank
tape. Using this tape, perform the Save and Verify
procedures on the system’s current translations. Then,
perform the Restore procedure using this test tape.
2     If the restoration is successful using the test tape, your
current system translation tape could be damaged.
Perform the Restore procedure using a previous backup
tape, or contact your AT&T service...

System Searches
System Searches describes how to search for various system information. Most searches
require a minimum of two levels of search specification. The first level identifies what we
might call the kind of search you want to begin (e.g., Search for Coverage Senders for a
particular group). The second level generally identifies the specific search object (e.g., the
Coverage Group). If there is a third level, it further defines the range of the search.
NOTE: Stations are identified by their PDC,...
