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)" Maintenance documentation.
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
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 the
reset board PCSS
command 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.
