ANN-PT (announcement port)

ANN-PT (announcement port)
The TN750 Announcement circuit pack is a service circuit pack that provides an integrated
means for recording announcements that can be played back on demand by call processing as
part of a calling feature (that is, announcements on hunt group calls). There are 16
Announcement Ports on the Announcement circuit pack. Each port can play any integrated
announcement, independently of the other ports. If there are any errors associated with the
circuit pack, refer to ANN-BD (Announcement circuit pack)
on page 447.
The Announcement circuit pack has two processors on it. The first processor, or Angel, controls
the circuit pack, and communicates with the switch via the control channel on the TDM Bus. The
second processor, or SP, controls the speech memory and announcements. Digital speech is
converted from its TDM Bus form to an internal storage form (for recording) and vice versa (for
playbacks) by the 140AY device on the circuit pack, which has 16 channels (one for each
Announcement Port).
General notes
Here are a few very important general notes that apply to any problem on the TN750
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/B 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 better to try to reset the circuit pack via reset board PCSS first and, if
that does not work, then try to reseat it. 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 system tape 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 pack is in proper working order (see Note).
Note:
Note: Unlike translations, announcements are NEVER automatically saved to the
memory card.
