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:
TN750C is required if your system will have multiple announcement boards.
To use multiple announcement boards, you must have G3V4 software, and
at least one TN750C (up to ten are allowed). 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).
1. Where P is the port network number (1 for PPN and 2 or 3 for EPN); C is the carrier
designation (for example, A, B, C, D, or E); and SS is the address of the slot in the carrier
where the circuit pack is located (for example, 01, 02, ..., etc.).
