General notes
Here are a few important general notes that apply to any problem on the Announcement circuit
pack. The user should read this before attempting to work on the TN750 Announcement circuit
pack or Announcement Ports, especially if the circuit pack needs to be replaced.
1. The TN750 Announcement circuit pack retains all integrated announcements as long as the
circuit pack has power. For this reason, whenever there is a problem with either the
Announcement circuit pack or an Announcement Port that may require the circuit pack to be
reset, it is always best to try to reset the circuit pack via reset board PCSS first. If that
does not work, replace the circuit pack. Announcements are preserved through a software
reset, but they are lost when the circuit pack is reseated.
2. If a customer has announcements on the Announcement circuit pack, then announcements
must be saved on the memory card to ensure that they are not lost. This should be done as
soon as the announcements are recorded on the circuit pack (or whenever they are
changed), assuming that the circuit pack is in proper working order (see Note).
Note:
Note: Unlike translations, announcements are NEVER automatically saved to the
memory card.
3. Save announcements replaces the TN750x announcement file on the memory card.
Care must be taken not to mistakenly enter this command and, as a result, destroy a valid
file on the memory card.
4. Restore announcements replaces the TN750x Announcement circuit pack speech
memory with the announcement file on the memory card. Care must be taken not to
mistakenly enter this command, destroying valid speech memory, especially if the memory
card does not have a valid announcement file on it.
5. Whenever the TN750x Announcement circuit pack is replaced, announcements must
always be rerecorded or downloaded to the new circuit pack. Otherwise, call processing is
not able to use the pack.
6. If announcement speech memory is corrupted, announcements should not be saved [that
is, if the Announcement Checksum Test (#209) fails, or if the speech sounds corrupted on
playback]. This can ruin a good announcement file on the memory card and potentially
cause errors/alarms on any circuit pack to which the new file is downloaded. However, if the
customer does not have a valid announcement file on the memory card, announcements
can be saved in an effort to try to retain some of them (all of the announcements recorded
may not be corrupted).
7. Due to a hardware fault in the TN750 announcement board, the following sequence of
events may cause the announcement file to become corrupted and unusable:
a. Fill the board with recorded announcements.
b. Delete the last few announcements recorded.
c. Re-record the announcements deleted.
