							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 perform Save, Verify, and Restore operations during system off-hours.
These operations can affect, and be affected by, normal System 25 operation.
Keep the following considerations in mind when performing tape save/restore operations:
n     Be sure connector “3” is assigned to the “Save/Restore Tape” capability (see
“Administering RS-232 Parameters” to reassign the connector).
n     Be sure the tape deck is plugged into connector “3” of the cable.
n     To save (Action = 1), you must press the PLAY and RECORD buttons.
n     To verify (Action = 2) and restore (Action = 3), you must press the PLAY button.
Caution: Action = 3 will interrupt phone service for about ten minutes.
Save/Restore
It is most unlikely that your System 25 will encounter a major catastrophe in which all your
translations are 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 ten minutes. It
takes only a few minutes to make a backup tape. It is important that you keep at least three
tapes of past translations, updating the two oldest tapes during system save procedures. If
something goes wrong during a save procedure and both tapes of the current system
translations are damaged, you will 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.
Administering Tape Save/Restore Operations 13-1 
						

							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, or
restore operation so you know that you are at the
beginning of the tape.
You do not have to be concerned about the clear “leader”
material at the beginning and end of the tape. The system
will start the tape at the correct point.
5     Press the STOP/EJECT button to disengage the REWIND
button.
Save Your Translations
To Save translations:1     Insert cassette and rewind the tape.
2     Press the RECORD and PLAY buttons simultaneously.
(The tape unit does not begin to operate yet.)
3     From the Main Menu prompt, enter 9 to select
Save/Restore.
4     At Action =, enter 1. You see:
Save/Restore: Action = 1 Data =
5     Type d and at Data = enter 1. You see this warning
message:

(Continued)
13-2 Administering Tape Save/Restore Operations 
						

							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 COMPLETED SUCCESSFULLY
7     Press the STOP/EJECT button on the tape unit.
8     Rewind the tape.
9     Follow the Verify procedure below.
If the Save is not successful, the SAT displays:
SAVE FAILED
1     Rewind the tape and repeat the Save procedure.
2     If this Save is successful, follow the previous steps (5-7).
3     If this Save is not successful, contact your AT&T service
representative.
Verify the Saved Translations
To begin: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.)

The tape unit stops when the verification is complete. If
the verification is successful, the SAT displays:
VERIFY COMPLETED SUCCESSFULLY
5     Rewind the tape.
6     Label the tape with the date and time. Store the tape in a
safe place.
If the verification is unsuccessful, the SAT displays:
VERIFY FAILED
To troubleshoot:1     Rewind the tape and repeat the verification procedure.
2     If this verification is successful, follow steps 5 and 6 above.
3     If the verification fails a second time, Save a new tape
following the above procedures, and contact your AT&T
service representative.

							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.

C for continue, any other key to abort
4     Type C.
The line now reads:
Save/Restore: Action = 3 Data = 1
At this point, the tape unit automatically starts the Restore
procedure and stops when the restoration is complete.
If the restoration is successful, the SAT displays:
INITIATED WARM START
Following this procedure, the system automatically “warm
starts” to initialize the system’s ports with the options read
into the system.
5     Rewind the tape.
6     Store the tape in a safe place.
If the restoration is not successful, the SAT displays:
RESTORE FAILED
Administering Tape Save/Restore Operations 13-5 
						

							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 representative.
3     If this restoration is not successful, do not use your backup
system translation tape. (Your digital tape unit may be
malfunctioning. If that is the case, it could destroy the
backup tape as well.) Contact your AT&T service
representative.

							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, DDC, or Display ID. For example, if you wanted
to search for the Coverage Senders for a particular group, your search session might run like
this:
Example:1     From the Main Menu prompt, enter 8.
2     When the search is defined, type C to search.
3     At 
Action =, enter 1.
4     At 
Data =, enter 1 for Coverage Sender search
To identify a search group:
1     At 
Action =, enter 2.
2     At 
Data =, enter 5.
3     Enter C to begin the search.
NOTE: Whenever you select 
SEARCH from the Main Menu,
you will see the message:
When search is defined type C to search.
You continue to enter C until you see Data = 0 which
indicates you have found all the searched-for items.
To search for an item:After entering 8 at the Main Menu, locate the kind of
information you want to search for from the following list and
complete the procedure.
