ANN-BD (Announcement Circuit
Pack)
The TN750 Announcement circuit pack is a service circuit which provides a
DEFINITY Generic 3 customer with an integrated means for recording
announcements that can be played back on demand by call processing as part of
a calling feature (for example, 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. In addition to the 16
Announcement Ports, the Announcement circuit pack also has one Data Line
Circuit Port (port 17). The Data Line Circuit Port is used for
uploading/downloading the announcement memory to/from the system tape
[G3iV1.1-286] or memory card [G3sV2, G3iV2-386, G3vsV2]. 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 port, refer to
“ANN-PT (Announcement Port)” Maintenance documentation.
NOTE:
To use multiple announcement boards, you must have G3V4 software or
later, and at least one TN750C (up to ten are allowed) or TN2501AP (VAL).
Only one TN750A/B may be present in the system when a TN750C is used.
The announcements from a TN750A/B can be saved and restored to a
TN750C — but once the announcements are recorded onto a TN750C, they
are not backward compatible with the TN750A/B.
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 Speech Processor (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).
