ANN-BD (Announcement circuit pack)
Note:
Note: The information contained in ANN-BD refers only to the TN750-series of circuit
packs. Expressions such as "announcement circuit pack" and "announcement
board" are to be interpreted to mean the TN750-series only.
The TN750 Announcement circuit pack is a service circuit which provides 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 memory card. If
there are any errors associated with port 17, refer to DAT-LINE (Data Line Port)
on page 870. If
there are any errors associated with any other port, refer to ANN-PT (announcement port)
on
page 465.
Note:
Note: TN750C is required if your system has multiple TN750x announcement boards
(up to ten are allowed). Only one TN750A/B may be present in the system with
up to nine additional TN750C boards. All ten boards may be TN750C. 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).
