Avaya 03-300430 User Manual

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:

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.
