ANN-PT (Announcement Port)
The TN750 Announcement circuit pac k is a service circuit p ack that provides an
integrated means for record ing announcements that c an be played b ack on
demand by c all processing as p art of a calling feature (that is, announc ements
on hunt group calls). There are 16 Announceme nt Ports on the Announcement
circuit pack. Each p ort can play any integ rated announcement, ind ependently of
the other ports. If there are any errors associated with the circuit pac k, refer to
"ANN-BD (Announcement Circuit Pack)" Maintenance doc umentation.
The Announcement circuit pac k has two processors on it. The first p rocessor, or
Angel, controls the circ uit pack, and c ommunicates with the switch via the control
channel on the TDM Bus. The second p rocessor, or SP, controls the speech
memory and announcements. Dig ital speech is conver ted from its TDM Bus form
to an internal storage form (for record ing) and vice vers a (for playbacks) b y the
140AY device on the circuit pac k, which has 16 channels (one for eac h
Announcement Port).

General Notes

Here are a few very important general notes that apply to any p roblem on the
Announcement circuit p ack. The user should read this before attemp ting to work
on the TN750 Announcement circuit p ack or Announcement Ports, especially if
the circuit pack needs to be replaced.
1. The TN750/B Announcement circuit pac k retains all integrated
announcements

as long as the circuit p ack has power

. For this reason,
whenever there is a problem with either the Announc ement circuit pac k or
an Announcement Port that may require the circ uit pack to be reset, it is
always better to try to reset the circ uit pack via the reset board PCSS
command first and, if that d oes not work, then try to reseat it.
Announcements are preserved through a software reset, but they are
lost when the circuit pack is reseated.
