ANN-BD (Announcement Circuit
Pack)
The TN750 Announcement circuit pac k is a service circuit whic h 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 (for examp le,
announcements on hunt group c alls). There are 16 Announcement Ports on the
Announcement circuit p ack. Each port c an play any integrated an nouncement,
independently of the other ports. In addition to the 16 Announcement Ports, the
Announcement circuit p ack also has one Data Line Circuit Port (p ort 17). The
Data Line Circuit Port is used for upload ing/downloadi ng the announcement
memory to/from the memory card. If there are any errors associated with port 17,
refer to ‘‘DAT-LINE (Data Line)’’ Maintenance documentation. If there are any
errors associated with any other p ort, refer to ‘‘ANN-PT (Announcement Port)’’
Maintenance documentatio n.
NOTE:
TN750C is required if your system has multip le announcement boards ( up
to ten are allowed). Only one TN750A/B may be present in the s ystem when
a TN750C is used. The announcements from a TN750A/B can be sav ed
and restored to a TN750C — but once th e announcements are recorded
onto a TN750C, they are not backward comp atible with the TN750A/B.
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 c ontrol
channel on the TDM Bus. The second p rocessor, or Speech Processor (SP),
controls the speech memory and announcements. Digita l speech is converted
from its TDM Bus form to an internal storage form (for rec ording) and vic e versa
(for playbacks) b y the 140AY device on the circuit pac k, which has 16 channels
(one for each 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.
