ANN-BD (Announcement Circuit
Pack)
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)’’
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 has multiple announcement boards (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).
General Notes
Here are a few
very important
general notes that apply to any problem on the
Announcement circuit pack. The user should read this before attempting to work
on the TN750 Announcement circuit pack or Announcement Ports,
especially if
the circuit pack needs to be replaced.
